The invention discloses a non-combustible fireproof insulation board which comprises the following components in percentage by weight: 90-95% of an inorganic flame retardant, 0.5-1.5% of a binder and 3-10% of polystyrene powder. The preparation method comprises the following steps: S1, dissolving a binder in water to form a binder solution for later use, wherein the concentration of the binder solution is 1-10%; S2, uniformly spraying the obtained binder solution on the surface of an inorganic flame retardant, then adding polystyrene powder, conducting stirring, and conducting drying after uniform stirring, so as to obtain coated polystyrene particles for later use; and S3, foaming the wrapped polystyrene particles obtained in the previous step in high-pressure water vapor for 1-6 hours, conducting standing and aging at normal temperature for 24-144 hours, and finally performing compression molding to obtain the non-combustible fireproof insulation board. The prepared insulation board is good in thermal insulation and energy-saving effect, low in water absorption rate and long in service life.
本发明公开了一种不燃防火保温板，按照重量比包括以下组分：无机阻燃剂90‑95％、粘结剂0.5‑1.5％、聚苯乙烯粉末3‑10％。其制备方法包括：S1：将粘结剂溶解于水中形成粘结剂溶液待用，其中粘结剂水溶液的浓度为1‑10％；S2：将上述得到的粘结剂溶液均匀喷洒在无机阻燃剂表面，然后再加入聚苯乙烯粉末进行搅拌，搅拌均匀后进行干燥，即可得到包裹聚苯乙烯颗粒待用；S3：将上述步骤得到的包裹聚苯乙烯颗粒在高压水蒸气下发泡1‑6h，再进行常温静置老化24‑144h，最后压制成型，得到不燃防火保温板。本发明制备的保温板保温隔热节能效果好，吸水率低，使用寿命长。
