环氧地坪漆的使用寿命一般在5-15年，但是有很多的环氧地坪漆才使用2-3年，甚至更短的时间就出现涂层大面积脱落的情况，这是什么原因呢?环氧地坪漆涂层大面积脱落分两种情况：a、环氧地坪漆涂层与混凝土基层结合界面破坏，表现为环氧涂层大面积出现脱落，而混凝土基层正常无损，直接原因是界面附着力不足。b、环氧地坪漆涂层与混凝土基层表面砂浆结合紧密，破坏面出现在混凝土基层内部，破坏面位于混凝土基层的砂浆平面。这种破坏形式一般大面积出现，直接原因是混凝土的抗拉强度不足。

The service life of epoxy floor paint is generally 5-15 years, but a lot of epoxy floor paint only use 2-3 years, or even shorter time, the large area of coating fall off. What's the reason? The large area of epoxy floor paint coating fall off into two situations: a. The interface between epoxy floor paint and concrete base is destroyed, which shows that the large area of epoxy coating falls off. But the concrete base course is normal and non-destructive, the direct reason is that the interface adhesion is insufficient. B. The epoxy floor paint coating is closely combined with the mortar on the surface of concrete base. The damage surface appears in the interior of concrete base, and the damage surface is located in the mortar plane of concrete base. This kind of failure generally occurs in a large area, the direct reason is that the tensile strength of concrete is insufficient.

环氧地坪漆涂层脱落的原因：

Reasons for coating peeling off of epoxy floor paint:

1、基础地面处理不到位，地面上的油污、水溶解物、锈迹等清理不干净，导致环氧底漆与基础地面没有粘结牢固。

1. Undertreatment of the base floor and unclean cleaning of oil, water-soluble substances and rust on the ground lead to no strong bond between epoxy primer and the base floor.

2、基础地面处理后与环氧地坪漆施工时的间隔时间过长，导致灰尘杂质出现在地表面。

2. The interval between the treatment of foundation ground and the construction of epoxy floor paint is too long, which results in the appearance of dust impurities on the surface.

3、基础地面的含水率偏高，没做防水层，就会有环氧地坪漆层脱落的风险存在。

3. The water content of the base floor is too high. If the waterproof layer is not made, there will be the risk that the epoxy floor paint will fall off.

4、基础地面表面太过光滑，没有进行打磨拉毛处理，就会导致环氧地坪漆与基层附着力不够，出现环氧地坪漆涂层脱落的现象。

4. The surface of the base floor is too smooth. Without polishing and brushing treatment, the adhesion between the epoxy floor paint and the base layer is not enough, and the coating of the epoxy floor paint falls off.

5、水泥地面强度不够，粉化严重，没有对水泥地面进行固化处理。

5. The strength of cement ground is not enough, and it is powdered seriously. There is no solidification treatment for cement ground.

防止环氧环氧地坪漆涂层大面积脱落的方法：

Method of preventing large area peeling off of epoxy floor paint coating:

1、基础地面上的油污杂物等一定要清理干净。

1. Oil and sundries on the ground must be cleaned up.

2、地下室等场所一定要做防水层，新做水泥地面要养护28天以上，确保含水率不高于8%才能进行环氧地坪漆施工。

2. Waterproof layer must be made in basement and other places. New cement floor should be maintained for more than 28 days to ensure that moisture content is not higher than 8% before epoxy floor paint can be constructed.

3、基础地面一定要用打磨机打磨拉毛，增强环氧地坪漆涂层与地面的附着力。

3. The base floor must be polished and brushed with a grinder to enhance the adhesion between the epoxy floor paint coating and the ground.

4、地面处理后要及时进行环氧地坪漆施工，如果间隔时间过长，需重新清理干净。

4. After surface treatment, epoxy floor paint should be constructed in time. If the interval is too long, it should be cleaned up again.

5、水泥地面强度需在C25以上，如果起砂起灰现象严重，一定要加固处理后方可进行环氧地坪漆施工。
