Preparation method and use method of repair paste for repairing wall cracks
The invention discloses a preparation method and a use method of repair paste for repairing wall cracks. The repair paste is prepared from 65-80 parts of quartz sand, 1-2 parts of titanium dioxide, 10-20 parts of polymer emulsion, 1-2 parts of a coalescing agent, 0.2-0.4 part of a preservative, 0.3-0.8 part of a thickening agent, 10-15 parts of deionized water and 0.3-0.5 part of an auxiliary component. The repair paste for repairing wall cracks developed by the invention is mainly used for repairing and preventing cracks, has the characteristics of strong adhesive force, good elasticity, water resistance, alkali resistance, environmental protection and the like of conventional elastic putty, takes the high-purity quartz sand as a main filler, is matched with the styrene-acrylate polymer mixed emulsion, combines the strength of an inorganic material with the flexibility of an organic material, and effectively reduces the shrinkage and collapse of the material by being matched with the action of an alkali swelling type thickening agent in the system. According to the invention, large cracks with the width of 20 mm can be directly repaired, auxiliary materials such as gridding cloth belts and kraft paper are not needed, the wall repairing agent of the same series is matched for use, and the effect is better.
本申请公开了一种墙面裂缝修补的修复膏制备及其使用方法，包括65‑80份石英砂、1‑2份钛白粉、10‑20份聚合物乳液、1‑2份成膜助剂、0.2‑0.4份防腐剂、0.3‑0.8份增稠剂、10‑15份去离子水和0.3‑0.5份辅助组分。本申请开发的墙面裂缝修复膏主要用于裂缝的修补与预防，除具备常规弹性腻子附着力强、弹性好、耐水、耐碱、环保等特点外，以高纯石英砂为主要填料，搭配苯乙烯‑丙烯酸酯聚合物混合乳液，将无机材料的强度与有机材料柔韧性结合，搭配体系中的碱溶胀型增稠剂的作用，有效的减少材料的收缩与塌陷；本发明可直接修补宽度达20mm的较大裂缝，无需借助网格布带、牛皮纸等辅助材料，搭配同系列的墙面修复剂使用，效果更佳。
