摘要：【中文】本发明提供了一种改性不饱和聚酯人造石板材，由以下重量百分比的原料制成：改性不饱和聚酯树脂23‑30%，色糊0‑5%，固化剂0.2‑10%，促进剂0.02‑1%，偶联剂0.1‑5%，助剂A 0‑1%，其余为填料，各原料的重量百分比之和为100%。所述改性不饱和聚酯树脂为环氧树脂改性不饱和聚酯树脂，其由以下重量百分比的组分制成：二甘醇20‑35%，其他醇类5‑20%，有机酸45‑65%，环氧当量为50‑600g/eq的环氧树脂0.5‑6%，其余为助剂B，各组分的重量百分比之和为100%。本发明提供的改性不饱和聚酯人造石板材同时具有较好的强度和韧性。 【EN】The invention provides a modified unsaturated polyester artificial stone plate which is prepared from the following raw materials in percentage by weight: 23-30% of modified unsaturated polyester resin, 0-5% of color paste, 0.2-10% of curing agent, 0.02-1% of accelerator, 0.1-5% of coupling agent, 0-1% of auxiliary agent A and the balance of filler, wherein the sum of the weight percentages of the raw materials is 100%. The modified unsaturated polyester resin is epoxy resin modified unsaturated polyester resin and is prepared from the following components in percentage by weight: 20-35% of diethylene glycol, 5-20% of other alcohols, 45-65% of organic acid, 0.5-6% of epoxy resin with the epoxy equivalent of 50-600g/eq, and the balance of auxiliary agent B, wherein the sum of the weight percentages of the components is 100%. The modified unsaturated polyester artificial stone plate provided by the invention has better strength and toughness.
