CN110387752A 一种高倍率PVC涂层发泡材料浆料的制备方法 无效 - 驳回

一种高倍率PVC涂层发泡材料浆料的制备方法
摘要：
本发明公开了一种高倍率PVC涂层发泡材料浆料的制备方法，其中浆料包括以下重量份的原料组成：发泡糊树脂粉100-300份；增塑剂10-70份；大豆油1-5份；钡锌稳定剂0.5-4份；钾锌稳定剂1-5份；AC发泡剂5-25份；填充剂10-50份；阻燃剂2-15份，根据本发明配方、工艺条件配制出来涂层PVC发泡浆料糊剂的发泡倍率可以达到6-8倍，以及配制出来的涂层PVC发泡浆料的透气性更均匀，另外浆料配方中添加钾锌稳定剂可以有效降低发泡温度，有利于发泡过程的控制，而且生产配制的PVC发泡浆料糊剂发泡效果均匀、细腻、表面平整、保温隔热和防噪音效果良好。
摘要（英）：

The invention discloses a preparation method of high-rate PVC coating foam material slurry. The slurry is prepared from raw materials in parts by weight as follows: 100-300 parts of foam paste resin powder, 10-70 parts of a plasticizer, 1-5 parts of soybean oil, 0.5-4 parts of a barium-zinc stabilizer, 1-5 parts of a potassium-zinc stabilizer, 5-25 parts of an AC foaming agent, 10-50 parts of filler and 2-15 parts of a flame retardant. The foam rate of PVC coating foam slurry paste prepared according to the formula under process conditions can reach 6-8 times, the prepared PVC coating foam slurry has more uniform air permeability, besides, the potassium-zinc stabilizer is added to the slurry formula, the foaming temperature can be effectively reduced, control of the foaming process is facilitated, the produced and prepared PVC foam slurry paste has uniform and fine foam effects, flat surface, thermal insulation and good noise prevention effect.
