一种高增韧团状模塑料
摘要：
本发明公开了一种高增韧团状模塑料，该团状模塑料由如下重量份的原料经聚合反应得到，其中：不饱和树脂60-80，低收缩剂10-40、固化剂1-2、脱模剂2-5、增韧剂4-20、晶须30-80、偶联剂2-5、填料100-250、玻璃纤维50-150。本发明采用端活性基团液态橡胶和晶须来增韧BMC材料。通过端乙烯基液态丁腈橡胶提高BMC材料的韧性，通过经活性端苯乙烯偶联剂处理的碳酸钙晶须提高BMC材料的强度，抵消液态橡胶加入使材料强度下降的趋势。从而得到强度不下降的高增韧BMC材料。
摘要（英）：

The invention discloses a highly-toughened bulk molding composition which is obtained by polymerization of the following raw materials by weight: 60-80 parts of unsaturated resin, 10-40 parts of low shrinkage agents, 1-2 parts of curing agents, 2-5 parts of mold release agents, 4-20 parts of toughening agents, 30-80 parts of whiskers, 2-5 parts of coupling agents, 100-250 parts of filling materials, 50-150 parts of glass fibers. The invention adopts end active group liquid rubber and whiskers to toughen the BMC material. The toughness of the BMC material is increased by end vinyl liquid butadiene-acrylonitrile rubber; the strength of the BMC material is increased by calcium carbonate whiskers treated by the active end styrene coupling agent; and the trend of the decrease of the strength of the material due to the addition of the liquid rubber is counteracted. Therefore, the highly-toughened BMC material is obtained without the decrease of the strength.
