Elastic thermal insulation slurry and preparation method thereof
The invention relates to elastic thermal insulation slurry and a preparation method thereof. The elastic thermal insulation slurry is prepared from the following raw materials in percentage by weight:8-12% of polymer emulsion, 10-12% of silica powder, 12-18% of coarse whiting powder, 25-30% of glass micro-beads, 6-8% of calcined kaolin, 4-5% of barium sulfate, 1-1.5% of a flame retardant, 0.2-0.5% of a wetting agent and the balance of water. According to the invention, the silica powder is used as a light skeleton, the polymer emulsion and the calcined kaolin are added at the same time, so that the binding power of slurry is improved, the slurry can be quickly coagulated, strong binding strength with a base material is generated and is up to 0.11 MPa, the cured propylbenzene emulsion is high in strength, good toughness of the product can be guaranteed, and after being mounted on a wall, the elastic thermal insulation slurry is not easy to crack and fall off; and the slurry is good inheat preservation performance, the vitrified micro bubbles are added, so that the heat conductivity coefficient of the obtained slurry is smaller than 0.053 W/(m.K), and the slurry has good flame retardance.
一种弹性保温浆体及其制备方法，由以下重量百分比的原料组成：聚合物乳液8‑12％、硅微粉10‑12％、重钙粉12‑18％、玻化微珠25‑30％、煅烧高岭土6‑8％、硫酸钡4‑5％、阻燃剂1‑1.5％、润湿剂0.2‑0.5％、余量为水；本发明采用硅微粉为轻骨架，同时加入聚合物乳液和煅烧高岭土提高了浆体的粘结力，可以快速凝结，与基材产生较强的粘结强度，高达0.11MPa，而且采用巴斯夫的丙苯乳液，使得固化后强度较高，而且可以保证产品具有较好的韧性，上墙后不易碎裂和脱落；而且浆体的保温性能好，添加了玻化微珠，使得到的浆体的导热系数小于0.053W/(m·K)，而且具备较好的阻燃性。
