    环氧地坪漆为什么会起皮与处理方法?

    2018-10-19 20:27:13 无锡盛发地坪科技有限公司 阅读

    环氧地坪漆涂装前表面处理不佳,被涂物表面上有油污、蜡,水汽、灰尘和化学药品等。或表面预处理后至涂漆旅工的间隔时间过长涂装前被涂物表面应处理清洁,并应立即涂装施工。底漆选择不当。如底漆的硬度过大。涂膜表面太平滑.都会使面漆和底漆间失去应有的黏附力应选用附着力和润湿性好的底漆。

    The surface of epoxy floor paint is poorly treated before painting. There are oil, wax, water vapor, dust and chemicals on the surface of the coating. Or the surface pretreatment to the paint traveler's interval is too long before the painting surface should be treated clean, and immediately painting construction. The primer is not properly selected. For example, the hardness of primer is too large. The surface of the film is too smooth. Primers with good adhesion and wettability should be chosen to make the surface and primer lose their due adhesion. 

    被涂物表面太光滑

    The surface of the coating is too smooth.

    被涂物表面应打磨或经化学处理。旧漆面应重新打磨处理。

    The surface of the coating should be ground or chemically treated. Old paint should be re ground. 

    环氧地坪漆配套不适当

    Improper matching of epoxy floor paint 

    通过试验选择配套性良好的涂料品种及改用“湿碰湿”工艺.或增加中间涂层。

    Through the test, we can choose the good matching coatings and adopt the wet-wet process or add the intermediate coatings. 

    在底漆未干透之前就罩面漆或清漆.漆膜易发生开裂或脱落,一般应在底漆完全干透后再罩面漆。

    Overcoat or varnish before the primer has dried thoroughly. The film is liable to crack or fall off, and should be covered after the primer has dried thoroughly. 

    在潮湿或霉染的物面上涂装.使漆与底材附着不良

    Painting on wet or mildew colored surfaces. Poor adhesion between lacquer and substrate.

    砖石、水泥等物面应充分干燥和除去霉染物后再涂装施工

    Brick, cement and other surfaces should be fully dried and removed after mold coating.

    涂膜太厚,由于表层已干透.而底层干得慢或未干透.

    The film is too thick because the surface is dry, and the bottom layer is slow or dry.

    在干燥过程中由于面漆收缩过甚而引起开裂脱落 施工中应注意每道漆的漆膜不宜太厚

    It should be noted that the film of each paint should not be too thick during the construction of cracking and shedding caused by excessive shrinkage of topcoat during drying process. 

    一、施工人员的过失或者是施工人员的经验不足。

    1. The fault of the construction personnel or the experience of the construction personnel is insufficient. 

    1、涂装前地表的处理不是很好,被涂物表面上有油污、蜡、水汽、灰尘和化学药品等,或表面预处理后至涂漆施工的间隔时间过长。

    1. The surface treatment before painting is not very good. Oil, wax, water vapor, dust and chemicals are on the surface of the coating, or the interval between surface pretreatment and painting is too long.

    2、被涂物表面的光滑过度,而没有进行针对性处理或没有选择针对性底涂材料。

    2. Excessive smoothness of the coated surface without targeted treatment or selection of targeted primer materials.

    3、在底漆未干透之前就罩面漆或清漆,涂膜易发生开裂或脱落;

    3. Cover the finish or varnish before the primer is dry. The coating will easily crack or fall off.

    4、涂膜太厚,由于表层已干透,而底层干得慢或未干透,在干燥过程中由于面漆收缩过甚而引起开裂脱落;

    4. Coating film is too thick, because the surface has dried through, and the bottom dried slowly or not thoroughly, in the drying process due to excessive shrinkage of the top paint caused cracking and shedding;

    5、施工环境温度高,涂装距离(喷涂)大,稀释剂挥发快,致使环氧地坪漆漆膜未流平,就使漆膜出现起皱橘皮现象。为了加快涂膜干燥,催干剂加入量太大,也会造成环氧地坪漆涂膜起皱。在高温下避免施工,或加强通风,降低施工环境温度,调整喷漆距离,适当加入慢干溶剂,减少催干剂用量,是避免和克服环氧地坪漆涂膜起皱的方法。

    5. The construction environment temperature is high, the painting distance (spraying) is big, the diluent volatilizes quickly, causes the floor paint film not to flow flat, causes the paint film to appear the wrinkled orange peel phenomenon. In order to accelerate the drying of film, too much addition of drier will cause wrinkling of epoxy floor paint film. Avoid construction at high temperature, or strengthen ventilation, reduce the construction environment temperature, adjust the spray distance, properly add slow-drying solvent, reduce the amount of drier, is to avoid and overcome the floor paint film wrinkling.

    6、底漆表干未完全干硬,或固化剂含量不足,地坪漆漆膜交联不充分就涂装面漆或多涂,即发生起皱咬底现象。使用聚合物含量高的硝基漆或水性漆作底漆,由于PVC含量低,也造成复涂面漆咬底。如面漆使用大量慢干的酮类等强溶剂,也容易使环氧地坪漆产生咬底现象。

    6. Primer surface is not completely dry, or curing agent content is insufficient, floor paint film cross-linking insufficient topcoat or multi-coating, that is, wrinkle underbite. The use of nitrolacquers or waterborne lacquers with high polymer content as primers, due to the low content of PVC, also causes the re-coated topcoat undercut. If the topcoat uses a lot of slow drying ketones and other strong solvents, it will make the epoxy floor paint easy to bite.

    7、要防止咬底,基料与固化剂的混合比例要严格控制,保证环氧地坪漆涂膜充分交联。复漆时间也要严格控制,要使底漆交联干固后,才复涂面漆。要适当提高底漆中的颜料体积比,并选用片状填料加强底漆的密实性,防止面漆溶剂过度渗透使地坪漆涂膜溶胀而产生咬底。

    7. To prevent underbite, the mixing ratio of binder and curing agent should be strictly controlled to ensure that the epoxy floor paint film is fully crosslinked. It is also necessary to strictly control the time of lacquer painting. The volume ratio of pigments in the primer should be appropriately increased, and sheet fillers should be selected to enhance the density of the primer, so as to prevent the overpenetration of the solvent in the top coat from causing the swelling of the coating film of the floor coat and causing the underbite. 

    二、 产品质量因素

    Two, product quality factors

    底漆附着力不足。

    Insufficient primer adhesion. 

    三、底漆选择不当

    Three. Improper primer selection

    在潮湿或霉染的物面上涂装,没有针对性的产品和措施。用单一品种底涂使用在所有类型的地面。

    On wet or mildew stained surfaces, there are no targeted products and measures. Use single primer for all types of ground.

    综上所述,环氧地坪起皮的问题只要针对性的采取措施不难解决,而且也被国内众多工程案例所证实。据我们了解目前市场上环氧地坪施工失败导致很快起皮最可能的原因是:

    To sum up, the problem of epoxy floor peeling is not difficult to solve as long as targeted measures are taken, but also confirmed by many domestic engineering cases. We understand that the failure of epoxy floor construction on the market is the most likely reason for skin peeling.

    1、底漆附着力不够;

    1. The adhesion of primer is not enough.

    2、地面含水率超过8%,而没有针对性措施。

    2, the surface water content exceeds 8%, and there are no specific measures.

    3、各区域含水率不均匀。导致部分潮湿区域起皮。

    3, uneven moisture content in each area. Cause skin in some damp areas.

    4、底漆没有防潮功能。

    4. Primer has no moistureproof function. 

    我们根据每个区域的特点进行有针对性的调整固化剂的配比率或选择不同的固化剂,以更好的适用于各种地面。在施工前,我们将排专业人员现场测试地面湿度,以确定是否适用。

    We adjust the proportion of curing agent according to the characteristics of each area or choose different curing agent to better apply to various ground. Before construction, we will arrange professionals to test the ground humidity on the spot to determine if they are applicable.

    成熟的工艺流程可以将环氧地坪做成0.3mm以上任意厚度,不会因为地坪漆的厚度过厚而造成环氧地坪的起皮现象。

    Mature process can be made of epoxy floor to any thickness of more than 0.3 mm, because the thickness of the floor paint will not cause the skin phenomenon of epoxy floor. 

    总结环氧地坪漆起皮的原因:

    The reason why epoxy floor paint is skinned is summarized.

    1、环氧树脂材料品质差,将导致地面不耐用、脱皮、脱层、变色、破裂等;

    1, the poor quality of epoxy resin will cause the ground to be undurable, peeling, delamination, discoloration and cracking.

    2、未能严格按标准施工,偷工减料,将导致地面不耐用、脱皮、脱层、破裂等;

    2. Failure to strictly comply with the standards of construction, jerry-building will lead to ground durability, peeling, delamination, rupture, etc.

    3、地面未做防潮层,将导致环氧地坪鼓泡、脱层等;

    3, the ground is not done moistureproof layer, will lead to epoxy floor bubble, delamination and so on.

    4、地面未清理干净,将导致环氧地坪脱层、脱皮等;

    4, the ground is not cleaned up, will lead to epoxy floor delamination, peeling and so on.

    5、环氧材料用量太少,将导致地面露底;

    5. Too little epoxy material will cause ground bottom.

    6、地面收缩缝未补好,将导致地面裂缝;

    6, the ground contraction joint is not filled, will cause ground cracks;

    7、环氧地坪在太阳的照射下,将导致退色;

    7, the epoxy floor will irradiate under the sun, resulting in fading.

    8、恶劣的天气或环境下施工,也将导致质量问题。

    8, construction in bad weather or environment will also lead to quality problems.
