The invention belongs to the technical field of building materials, and particularly relates to an environment-friendly composite polyester plate and a preparation method thereof. The composite polyester board is prepared from the following raw materials in percentage by weight: 36-45% of calcium powder, 36-45% of quartz sand, 2-5% of unsaturated polyester, 1-3% of polystyrene, 0.5-2.5% of a toughness regulator, 1-3% of styrene, 0.1-1% of a curing agent, 1-3% of a release agent and 5-10% of glass fibers. According to the invention, polystyrene is added to reduce the shrinkage rate of unsaturated polyester, the use amount of unsaturated polyester is reduced, the cost is reduced, the toughness modifier is added to increase the adhesive property, and all the raw materials are combined, so that the obtained composite polyester plate is not easy to curl and warp, high in strength, good in toughness and more economical and environment-friendly.
本发明属于建筑材料技术领域，具体涉及一种环保型复合聚酯板材及其制备方法，所述复合聚酯板材由如下重量百分比的原料制成：钙粉36‑45％、石英砂36‑45％、不饱和聚酯2‑5％、聚苯乙烯1‑3％、韧性调节剂0.5‑2.5％、苯乙烯1‑3％、固化剂0.1‑1％、脱模剂1‑3％和玻璃纤维5‑10％。本发明通过加入聚苯乙烯来降低不饱和聚酯的收缩率，而且降低不饱和聚酯的用量，降低成本，加入韧性调节剂增加粘结性能，各原料合用，所得复合聚酯板材不易卷曲翘边，强度高，韧性好，更加经济环保。
