Putty with crack repairing function and preparation method thereof
The invention relates to putty with a crack repairing function, which comprises a liquid material and a powder material, the liquid material is prepared from the following raw materials: pure deionized water, a dispersing agent, a wetting agent, emulsified asphalt and VAE emulsion, and the powder material is prepared from the following raw materials: grey cement, quartz sand, heavy calcium powder, hydroxypropyl methyl cellulose ether, a polycarboxylic acid water reducing agent, wood fibers, hydroxypropyl starch ether and fumed silica. The provided putty not only has a flexible property of conventional putty in the primary stage, but also has a crack self-repairing function and can automatically repair fine micro-cracks, caused by cracking of a base layer, of a putty layer, the overall flexibility of a decorative layer is improved, and later-stage falling and repairing risks are reduced; the exterior wall putty product with the crack repairing function can greatly reduce the overall maintenance cost of building decoration engineering and prolong the service life of a building exterior wall decoration layer; and therefore, the development and research work of the putty with the crack repairing function is carried out.
本发明涉及一种具有裂纹修复功能的腻子,包括液料和粉料,所述液料由以下原料组成:纯净去离子水、分散剂、润湿剂、乳化沥青、VAE乳液、所述粉料由以下原料组成:灰水泥、石英砂、重钙粉、羟丙基甲基纤维素醚、聚羧酸减水剂、木质纤维、羟丙基淀粉醚、气相二氧化硅,本发明突破传统腻子只具有初期柔韧性功能,使其具有裂纹自修复功能,可自行修复因基层开裂导致的腻子层出现的细小微裂纹,提升装饰层整体柔性,降低后期脱落及返修风险;具有裂纹修复功能的外墙腻子产品可大大减少建筑装饰工程整体维修费用,提升建筑外墙装饰层寿命;因此进行了具有裂纹修复腻子的开发研究工作。
