Polyphenyl insulation board and preparation method thereof
The invention discloses a polyphenyl insulation board and a preparation method thereof. The insulation board comprises EPS particles, a flame-retardant adhesive and a grouting material, the grouting material is prepared from Portland cement, a water reducing agent, cellulose ether and water; the flame-retardant adhesive is prepared from the following raw materials: a compound fireproof raw material, styrene-acrylic emulsion, polyvinyl alcohol, silica powder and water, the compound fireproof raw material is prepared from magnesium hydroxide, calcium carbonate and aluminum hypophosphite. The preparation method comprises the following steps: heating the EPS particles with high-temperature steam for pre-foaming, then putting the EPS particles into the flame-retardant adhesive, uniformly stirring and mixing, drying, and then putting into a mold for heating and forming to prepare the insulation board with a gap structure; and filling holes of the insulation board with the grouting material to obtain the polyphenyl insulation board. According to the method, the preparation process is simple, the cost is low, the used raw materials are easy to obtain, and the obtained polyphenyl insulation board not only has an excellent flame retardant effect, but also has the advantages of small heat conductivity coefficient, low volume weight, excellent mechanical properties and the like, and can better meet the requirements of the current building external wall insulation material market.
一种聚苯保温板及其制备方法，该保温板包括EPS颗粒、阻燃型胶黏剂和灌浆料；灌浆料由硅酸盐水泥、减水剂、纤维素醚、水制备而成；阻燃性胶黏剂包括以下原料：复配防火原料、苯丙乳液、聚乙烯醇、硅微粉、水；复配防火原料由氢氧化镁、碳酸钙和次磷酸铝组成。制备方法：将EPS颗粒用高温蒸汽加热进行预发泡后置于阻燃型胶粘剂中，搅拌混合均匀并烘干，然后放入模具中加热成型制成具有空隙结构的保温板；将灌浆料填充至保温板孔隙之中即制得聚苯保温板。该方法制备工艺简单、成本低，使用原料易获取，所得到的聚苯保温板不仅具有优异的阻燃效果，还具有导热系数小、低容重、力学性能优异等优点，可更加适应目前建筑外墙保温材料市场的需求。
