摘要
紫胶是一种重要的林特产品,我国的年产量仅次于印度、泰国居世界第三位。本研究首次采用紫胶的改性产品(RL_2树脂)改性酚醛模塑料通用类产品(PF_2A_2131、PF_2A_2141)获得成功。产品质量达到或超过GB1404—86规定的各项技术指标,成本比不用紫胶树脂改性的同类产品约降低10％。填补了国内紫胶树脂用于生产紫胶改性酚醛模塑料的空白。
Lac is an important forest products. Its output, Which is only next to India and Thailand, ranks China third in the world. In our experiments modified lac resin (RL_2) has been first and successfully used to make generalpurpose products of modified lac phenolic mouldiong material (RL_2-PF_2A_2131 and RL_2-PF_2A_2141), and these p products have satiisfied all the quality indexes stipulated in GB1404-86 with production cost decreased by 10% compared with those nonmodified lac resin products. Also our experiments have filled in the gap of using lac resin to produce modified lac phenolic moulding materials in China.
