High-strength fiber reinforced foamed cement insulation board and preparation method thereof
The invention relates to a high-strength fiber reinforced foamed cement insulation board and a preparation method thereof. The foamed cement insulation board is mainly prepared from water and the following raw materials by weight: 95-96 parts of ordinary Portland cement, 4.0-5.0 parts of silica fume, 0.50-0.60 part of a water reducing agent, 6.0-7.0 parts of a foaming agent hydrogen peroxide, 1.6-2.0 parts of calcium stearate, 0.5-0.6 part of a coagulant, 5.5-6.5 parts of microcrystalline foam glass slag, 7.0-8.0 parts of a styrene-acrylic emulsion and 0.45-0.60 part of polypropylene fiber; wherein the water-binder ratio is 0.55-0.57. According to the invention, the microcrystalline foam glass slag and the styrene-acrylic emulsion are used as inorganic-organic reinforcing materials, the obtained high-strength fiber reinforced foamed cement insulation board is good in appearance quality, low in heat conductivity coefficient, good in heat preservation and insulation performance, fireproof and flame-retardant performance, high in strength, low in volume water absorption, good in freeze-thaw cycle resistance, good in durability and long in service life.
本发明涉及一种高强纤维增强发泡水泥保温板及其制备方法，该发泡水泥保温板主要由水和以下重量份的原料制成：普通硅酸盐水泥95‑96份、硅灰4.0‑5.0份、减水剂0.50‑0.60份、发泡剂双氧水6.0‑7.0份、硬脂酸钙1.6‑2.0份、促凝剂0.5‑0.6份、微晶泡沫玻璃渣5.5‑6.5份、苯丙乳液7.0‑8.0份、聚丙烯纤维0.45‑0.60份；水胶比为0.55‑0.57。本发明采用微晶泡沫玻璃渣和苯丙乳液作为无机‑有机增强材料，所得高强纤维增强发泡水泥保温板外观质量好，导热系数低，具有良好的保温隔热、防火阻燃性能及较高的强度、较低的体积吸水率、良好的抗冻融循环性能，耐久度好，使用寿命长。
