    底涂,是环氧地坪漆施工工艺中最重要的一步,只有这一步做好了,才能够继续在基面上面进行下一步涂装。所以,一般对用于环氧地坪涂装的底漆的要求为:应与基材有良好的附着力;本身具有良好的机械强度;对底材具有良好的保护性能和不起不利的副作用;能为以后的涂层创造良好的基础,不能含有渗入上层涂膜引起弊病的组分;更要具有良好的施工性和干燥性。涂布底漆时一般应注意要在表面处理以后严格按照规定的时间及时涂布底漆。还要根据底漆品种规定的条件在底漆干燥后规定的时间范围内涂下一道漆。过早涂布可能引起咬底及底漆中溶剂挥发困难导致漆膜干燥时间延长‘固化不良、鼓泡等情况;涂布达迟可能引起层间附着不良,且过迟涂布易由于粉尘积累或其他污染影响表观质量。为增加下一道涂层与底漆间的附着力,可在涂布前将底漆打磨。

    Primer is the most important step in the construction process of epoxy floor paint. Only when this step is completed, can the next step be continued on the base surface. Therefore, the general requirements for primers used for floor coating are: good adhesion with the base material; good mechanical strength; good protective performance and no adverse side effects on the base material; good foundation for future coatings, can not contain the components that cause defects by infiltrating into the upper coating film; and better workability and dryness. When applying primer, attention should be paid to the timely application of primer after surface treatment in strict accordance with the stipulated time. It is also necessary to apply a paint within the specified time range after the primer is dried according to the conditions prescribed by the primer varieties. Early coating may lead to underbiting and difficulty in solvent evaporation in primer, which may lead to prolonged drying time of paint film, such as poor curing, bubbling, etc. Late coating may lead to poor adhesion between layers, and late coating may easily affect the apparent quality due to dust accumulation or other pollution. In order to increase the adhesion between the next coating and the primer, the primer can be polished before coating.

    涂布底漆的方法一般可采用辊涂、刷涂和喷涂。刷涂施工效率较低,一般在边角处施工采用。最常用的是辊涂,效率高。

    Roller coating, brushing and spraying are commonly used for primer coating. Brushing construction efficiency is low, generally in the corner construction. The most commonly used is roll coating, high efficiency. 封闭底漆施工:

    Closed primer construction:

    用刷涂、辊涂或喷涂的方法施工封闭环氧地坪漆底漆一道至两道,两道之间的间隔时间在8h以上,但不能大于48h。对于旧地面,应增加一道底漆。底漆施工时应注意涂布均匀,涂膜无明显的厚度差异,防止漏涂。用辊涂法施工应注意余料堆积情况。底漆封闭不完全(漏涂)时,会发生附着不牢、涂膜起泡等现象。

    Brush, roll or spray method is used to construct one or two primers for closed floor paint. The interval between the two primers is more than 8 hours, but not more than 48 hours. For the old ground, a primer should be added. During primer construction, attention should be paid to uniform coating, no obvious thickness difference of coating film, to prevent leakage of coating. Pay attention to the accumulation of surplus materials in roller coating construction. When the primer is incompletely sealed (missing coating), there will be some phenomena such as weak adhesion and blistering of the coating film.

    1.底漆漆膜厚度根据底漆品种确定,应注意控制。表面无浮尘及松散砂粒。

    1. The thickness of primer film is determined according to the type of primer. Attention should be paid to its control. There is no floating dust and loose sand on the surface.

    2.含颜填料的底漆在使用前和使用过程应注意搅拌均匀

    2. The primer containing pigments and fillers should be stirred evenly before use and during use.

    3.注意遵守干燥的规范。在底涂上如涂含有强溶剂的涂料时,底漆必须干透,以免出现咬底等漆病。

    3. Pay attention to the standard of drying. When the primer is coated with paint containing strong solvents, the primer must be thoroughly dried to avoid primer biting and other paint diseases.

    4.增加下一道涂层与底漆间的附力,可在涂布前将底漆打磨。

    4. To increase the adhesion between the next coating and the primer, the primer can be polished before coating.

    5.要在漆前表面处理以后严格按照规定的时间及时涂布底漆。还要根据底漆品种规定的条件在底漆干燥后规定时间范围内涂下一道漆。过早涂布可能引起咬底及底漆中溶剂挥发困难导致漆膜干燥时间延长、固化不良的情况;涂布过迟可能引起层间附着不良,且过迟涂布易由于粉尘积累或其他污染影响表观。

    5. Primer should be coated in time after surface treatment. Also, according to the conditions specified by the primer varieties, a coat should be applied within the prescribed time range after the primer is dried. Early coating may lead to underbiting and difficulty in volatilization of solvents in primers, which may lead to prolonged drying time and poor curing of the film; late coating may lead to poor adhesion between layers, and late coating may easily affect the appearance due to dust accumulation or other pollution.

    底漆稀释按照说明书和环氧树脂地坪漆施工需要进行,控制好比例,严禁过量稀释。

    Primer dilution shall be in accordance with the instructions and the construction requirements of epoxy floor paint, and the proportion shall be well controlled, and excessive dilution shall be strictly prohibited.

    须在基面充分干燥、无异物的情况下进行,对地面必须进行清扫处理,对不符合要求的地面应及时向项目经理反映。

    It should be carried out under the condition that the foundation is fully dry and free of foreign matter, and the ground must be cleaned up. The ground that does not meet the requirements should be reported to the project manager in time.

    环氧树脂地坪漆材料开桶后,应充分搅拌均匀再进行使用。

    After opening the barrel, the epoxy floor paint material should be fully stirred and evenly used.

    先刷边角及不易棍涂的部位,再由上往下进行大面积施工,不易吸料的地坪用毛刷点刷环氧树脂地坪漆底涂。

    First brush the corners and the parts which are not easy to stick, then carry out large-scale construction from top to bottom, and brush the epoxy floor paint primer with a brush on the floor which is not easy to absorb materials.

    涂刷时,桶内必须设置滚板,棍筒和毛刷蘸料后必须在滚板上舔料后方可进行施工。

    When painting, the barrel must be equipped with rollers, and the barrel and brush dipping materials must be licked on the rollers before construction can be carried out.

    若有毛刷毛或棍筒毛沾在墙上,应及时处理。

    If there is brush or stick hair on the wall, it should be dealt with in time.

    由于溶剂挥发较快,若施工过程中底涂变稠影响施工,可适量添加溶剂,不过一般情况下,不建议采取这种办法。

    Due to the rapid volatilization of solvents, if the bottom coating becomes thicker in the construction process, the solvents can be added appropriately, but in general, this method is not recommended.

    检查地面是否有漏涂现象并加以修补。

    Check the ground for leakage and repair it.

    重涂时间一般大于6-8小时。

    Repainting time is usually more than 6-8 hours.

    环氧地坪漆施工效果涂布率满足要求;不允许有漏涂现象和流坠、明显的接搓,做到棍涂均匀。若实际涂布率与该涂布率相差较大,应报请项目经理。

    The coating rate of epoxy floor paint meets the requirement of construction effect, and no leakage, drop and obvious rubbing are allowed to make the stick coating uniform. If there is a big difference between the actual coating rate and the coating rate, the project manager should be informed.

    环氧树脂地坪漆施工的步骤中,底涂是至关重要的一点,只有将基面封闭好了,才能够进行下一步涂装,如果底涂没有做好,就算后面的工艺做得再好,都将功亏一篑。

    In the process of epoxy floor paint construction, the primer is the most important point. Only when the base is sealed, can the next painting be carried out. If the primer is not done well, even if the later process is done well, it will lose a lot.

    其他方面要注意的:

    Other aspects should be noted:

    腻子修补:

    Putty Repair:

    对水泥基层存在的凹坑,用商品环氧腻子或用底漆和细石英砂配置的环氧砂浆填平,在固化成膜后打磨平整。

    The pits in cement base are filled with commercial epoxy putty or epoxy mortar with primer and fine quartz sand, and polished flat after solidification.

    中层涂料施工:

    Medium coating construction:

    对于厚膜型涂料,中层涂料施工时可采用镘刀镘涂。由于涂料中使用的石英砂较多,一般情况下刮涂后涂膜不会出现明显刮刀痕迹,但如果石英砂加入量过大,刮痕明显时应辊压一次。涂装间隔如果大于48h,应进行打磨后再进行下道涂料的施工,以保证层间黏结力。

    For thick film coatings, the medium coatings can be applied with trowel. Due to the use of more quartz sand in coatings, there will be no obvious scraper marks on the coatings after scratching, but if the amount of quartz sand is too large, the scratch should be rolled once. If the coating interval is more than 48 hours, the next coatings should be polished to ensure the interlayer cohesion.

    面涂料施工:

    Surface coating construction:

    根据环氧耐磨地坪涂料的种类,面涂料可以采用刷涂或刮涂施工。对于厚膜型涂料,按配比要求将两组份涂料混合均匀,待熟化后使用1mm刮板刮涂涂料。刮涂时应尽量保持厚膜均匀,无漏涂现象,无明显余料。刮涂时,刮刀的移动速度应均匀,刮刀与地面平面夹角为30°左右,以保证涂膜厚度。刮涂道数根据厚度要求而定。普通环氧涂料则可以采取刷涂方法施工。面涂料施工时两道之间的间隔时间应在18h以上,但不能大于48h。配置好的涂料应尽快用完,以防止涂料的黏度升高,涂料中的气泡难于排出。

    According to the types of epoxy wear-resistant floor coatings, surface coatings can be applied by brushing or scraping. For thick film coatings, mix the two components evenly according to the proportion requirement, and then use 1 mm scraper to scrape the coatings after ripening. When scraping, we should try our best to keep the thick film uniform, no leakage and no obvious surplus. When scraping, the moving speed of the scraper should be uniform, and the angle between the scraper and the ground plane should be about 30 degrees, so as to ensure the film thickness. The number of scraping paths depends on the thickness requirement. Ordinary epoxy coatings can be applied by brushing method. The interval between the two coatings should be more than 18 hours, but not more than 48 hours. The coatings should be used up as soon as possible to prevent the increase of the viscosity of the coatings and the difficulty of discharging the bubbles in the coatings.

    环氧地坪养护:

    Epoxy Floor Maintenance:

    面涂料施工完,并完全固化后,一般应在面涂料施工24h以上方可上人,72小时后方可重压。(25℃为准,低温开放时间需适度延长。)

    After the surface coating is finished and solidified completely, it should be applied for more than 24 hours before it can be applied, and then it can be re-pressed after 72 hours. (The opening time at low temperature should be prolonged moderately, whichever temperature is 25 C.)
