| 硅质聚苯板又称为硅质改性聚苯板或硅质热固性聚苯板，是在传统的聚苯板基础上进行改良，达到B1阻燃效果的新型保温隔热材料。它不仅延续了传统聚苯板导热系数小、保温隔热效果好等优点，而且弥补了传统泡沫板阻燃效果差的缺点，在市场上，是一种较为理想的保温隔热材料。 Silicon polystyrene board, also known as silicon modified polystyrene board or silicon thermosetting polystyrene board, is a new type of thermal insulation material which is improved on the basis of traditional polystyrene board to achieve B1 flame retardant effect. It not only extends the advantages of traditional polystyrene board, such as small thermal conductivity and good thermal insulation effect, but also makes up for the poor flame retardant effect of traditional foam board, and is an ideal thermal insulation material in the market. 硅质聚苯板实际上是将有机聚苯板经硅化处理而成，相当于以普通聚苯板，在聚苯颗粒大分子表面涂覆一层防火材料，硅化后的聚苯板容重有所增加，但是它保持了原有聚苯板良好的保温性，又在火攻时瓷化，从而提高了一定的防火性能，即使这样，硅质聚苯板的防火等级只能达到B1级。而且它的抗拉强度和压缩强度偏低（抗拉强度≥7.5KPa、压缩强度≥40 KPa），所以其韧性不足。同时相对普通B1级聚苯板价格偏高，这就导致产品在市场上的竞争力有所下降。 Siliceous polystyrene board is actually made of organic polyphenylene board by silicification, which is equivalent to coating a layer of fireproof material on the surface of polystyrene particles and macromolecules with ordinary polystyrene board. The volume weight of silicified polystyrene board increases, but it maintains the good thermal insulation property of the original polystyrene board, and it is porcelain-plated in the fire attack, thus improving the fire-proof performance Fire rating can only reach B1. Moreover, its tensile strength and compressive strength are low (tensile strength ≥ 7.5kpa, compressive strength ≥ 40kpa), so its toughness is insufficient. At the same time, the price of grade B1 polystyrene board is relatively high, which leads to the decline of the competitiveness of products in the market. |
