Fiber-reinforced foam cement insulation board surface waterproof modification method
The invention relates to a surface waterproof modification method for a fiber-reinforced foamed cement insulation board. The method comprises the steps: coating the surface of the fiber-reinforced foamed cement insulation board with a composite waterproof coating to form a composite waterproof layer, wherein the composite waterproof coating is mainly prepared from polyisocyanates and the followingraw materials in parts by weight: 100 parts of polyether polyol, 0.5-0.6 part of a dispersing agent, 15-20 parts of a plasticizer, 39-41 parts of superfine cement, 4-6 parts of silica fume, 10-12 parts of talcum powder, 0.5-0.6 part of hydrogenated castor oil, 0.1-0.2 part of a defoaming agent, 0.3-0.4 part of a catalyst, 1.0-1.5 parts of a latent curing agent and 10-12 parts of solvent oil. According to the waterproof modification method, a composite waterproof layer with the thickness of 0.5-5.0 mm is formed on the surface of the fiber-reinforced foamed cement insulation board, the volume water absorption rate of the board is greatly reduced, the reduction rate reaches 80% or above, the freeze-thaw cycle resistance and durability of the board are improved, and the service life of the board is prolonged.
本发明涉及一种纤维增强发泡水泥保温板表面防水改性方法，包括在纤维增强发泡水泥保温板的表面涂覆复合防水涂料形成复合防水层；复合防水涂料主要由多异氰酸酯和以下重量份的原料制成：聚醚多元醇100份、分散剂0.5‑0.6份、增塑剂15‑20份、超细水泥39‑41份、硅灰4‑6份、滑石粉10‑12份、氢化蓖麻油0.5‑0.6份、消泡剂0.1‑0.2份、催化剂0.3‑0.4份、潜固化剂1.0‑1.5份、溶剂油10‑12份。该防水改性方法在纤维增强发泡水泥保温板表面形成厚度为0.5‑5.0mm的复合防水层，大幅降低了板材的体积吸水率，下降率达到80％以上，提高了其抗冻融循环性能和耐久度，延长其使用寿命。
