Anti-cracking real stone paint and construction process thereof
The invention relates to the technical field of real stone paint preparation and construction technology, and provides an anti-cracking real stone paint and a construction technology thereof.In the process of preparing a modified acrylic resin solution, a vinyl-terminated waterborne polyurethane prepolymer is synthesized firstly and then polymerized to form a modified acrylate emulsion, and then the modified acrylate emulsion is added into the anti-cracking real stone paint to prepare the anti-cracking real stone paint. The silane coupling agent is added in the process of forming the modified acrylate emulsion, and the silane coupling agent can be introduced into polymeric molecules, so that modification is completed, and the flame retardance, corrosion resistance and water resistance of the modified acrylate emulsion are improved. In the preparation process of the anti-cracking real stone paint, the viscosity of the anti-cracking real stone paint is maintained at 300-350 Pa * s, the anti-cracking real stone paint can be kept in a bonding state, the flexibility of the anti-cracking real stone paint is improved, the anti-cracking effect is achieved, finally, the construction technology of the anti-cracking real stone paint can overcome the defect that an outer wall coating is prone to peeling and falling after being used for a long time, and the anti-cracking real stone paint can be applied to the exterior wall. And the cracking probability of a paint film of the paint layer can also be reduced.
本发明涉及真石漆制备及施工工艺技术领域，提供一种防开裂真石漆及其施工工艺，本发明在制备改性丙烯酸树脂溶液的过程中，先合成端乙烯基水性聚氨酯预聚体，再聚合形成改性丙烯酸酯乳液，在形成改性丙烯酸酯乳液的过程中加入硅烷偶联剂，能够将硅烷偶联剂引入到聚合分子中，从而完成改性提高改性丙烯酸酯乳液的阻燃性、耐腐蚀性和耐水性。而且在制备防开裂真石漆的过程中，使防开裂真石漆的粘度维持在300‑350Pa*s能够保持黏结状态，提高防开裂真石漆的柔韧性，从而起到防开裂的作用，最后，本发明中防开裂真石漆的施工工艺，能够解决外墙涂料时间长易起皮掉落的缺点，还能够降低漆层涂膜开裂的几率。
