    什么原因导致环氧地坪漆施工后一直发黏?怎么解决

    环氧地坪漆是双组份地坪材料,使用时需按比例混合搅拌均均,一般施工完工后24小时就会表干,但是一些新手在做环氧地坪漆时,经常会遇到环氧地坪漆施工后经过一段时间表面仍然发黏的现象。发黏是在环氧地坪漆施工干燥后,经过一段时间仍有一些黏指的现象或者是已干燥的涂膜又出现黏性的现象。那么是什么原因导致环氧地坪漆施工后发黏呢?

    Epoxy flooring paint is a two-component flooring material, which needs to be mixed and stirred proportionally. Generally, the surface will dry 24 hours after the completion of construction. However, some novices often encounter the phenomenon that the surface of epoxy flooring paint is still sticky after a period of construction. Adhesion is the phenomenon that after the drying of epoxy floor paint, there are still some sticky fingers or the drying film appears again. So what causes epoxy floor paint to stick after construction?

    环氧地坪漆发黏的原因主要有以下几个方面:

    The main reasons for the stickiness of epoxy floor paint are as follows:

    1、基础地面处理不到位

    1. Undertreatment of Foundation Ground

    环氧地坪漆施工前没有将基础地面上存在的油渍、酸碱物、蜡质等清理干净,温度上升时,这些污染物质会从固态变成液态开始流动并渗出,导致环氧地坪漆发黏、起壳。

    Before the construction of epoxy floor paint, the oil stains, acid and alkali, wax on the foundation floor were not cleaned up. When the temperature rises, these pollutants will flow from solid to liquid and seep out, resulting in the stickiness and shelling of epoxy floor paint.

    2、施工问题

    2. Construction problems

    环氧地坪漆施工工艺包括底漆施工、中涂砂浆层施工、中涂腻子层施工和面漆施工,如果在上一道工序还没干透就进行下一道工序的施工就可能会导致施工后环氧环氧地坪漆发黏。

    The construction technology of epoxy floor paint includes primer construction, middle mortar layer construction, middle putty layer construction and top paint construction. If the previous process is not completely dry, the construction of the next process may cause the epoxy floor paint to stick after construction.

    3、环境问题

    3. Environmental issues

    环氧环氧地坪漆施工环境要控制在温度10-25摄氏度,相对湿度75%以下,混凝土含水率8%以下。在湿度大于75%的情况下,会引起涂装表面结露,凝结的水会对固化剂造成破坏引起涂膜发白、失光、发黏、回黏等现象,大大降低表面装饰效果。

    The construction environment of epoxy floor paint should be controlled at 10-25 degrees Celsius, 75% relative humidity and 8% moisture content of concrete. When the humidity is more than 75%, condensation will occur on the surface of the coating. Condensed water will damage the curing agent and cause the phenomenon of whitening, losing light, sticking and sticking back of the coating, which greatly reduces the decorative effect of the surface.

    4、皂化现象

    4. Saponification Phenomenon

    混凝土地面如果含有碱性物质,环氧地坪漆施工上去会出现皂化,从而出现涂膜发软,黏度上升的现象。

    If the concrete floor contains alkaline substances, the epoxy floor paint will be saponified during construction, which will cause the film to become soft and the viscosity to rise.

    防止环氧地坪漆施工后发黏的方法:

    Method of preventing adhesion of epoxy floor paint after construction:

    1、环氧地坪漆施工前一定要将基础地面上的油污、酸碱物、蜡质等清理干净。

    1. Before the construction of epoxy floor paint, it is necessary to clean up the oil, acid, alkali and wax on the foundation floor.

    2、施工时一定要在第一道漆充分干透之后再涂二道漆。

    2. The first paint must be thoroughly dried before applying the second paint.

    3、在高温高湿场合下施工,应适当延长每道漆施工的间隔时间,所以在阴雨天尽量不施工面漆。

    3. In the case of high temperature and high humidity, the construction interval of each paint should be prolonged appropriately, so the top coat should not be applied as far as possible in cloudy and rainy days.

    4、在含碱性物质的底材涂装前应洗净或在其上涂上抗碱封闭底漆。刚砂、石英砂,所有裸露水泥的地面,整体上色和骨科硬化的混凝土地面都在用混凝土密封固化剂来做
