Abstract: The glass fiber as reinforced skeleton, unsaturated polyester resin as matrix materials, then the dust suppression and wind proofing plate was prepared. The effects of the ratio of unsaturated polyester resin and glass fiber, the species of glass fiber, the contents of curing agent and accelerating agent on the mechanical properties on dust suppression and wind proofing plate were studied. The results are as follows: the tensile strength and impulse strength were up to maximum when the mass ratio of unsaturated polyester and glass fiber felt was 3∶1. The tensile strength of dust suppression and wind proofing plates which were enhanced by [KG*4]high [KG*4]alkali、the [KG*4]alkali [KG*4]and [KG*4]the [KG*4]non-alkali [KG*4]glass fiber felt respectively achieved [KG*4]to 55.198，75.249，89.446 MPa. The impulse strength respectively achieved to 30.699,35.367,41.343 kJ/m². Then the tensile strength of non-alkali glass fiber felt increased 62% than high alkali glass fiber felt, and it increased 18.8% than alkali glass fiber felt. The impulse strength of non-alkali glass fiber felt increased 34.7% when compared with high alkali glass fiber felt and it increased 16.9% than alkali glass fiber felt. When the content of accelerating agent and [KG*4]curing [KG*4]agent [KG*4]was [KG*4]respectively 0.5% and 1%, the maximum tensile strength of dust suppression and wind proofing plate is 89.446 MPa, the maximum impulse strength is 41.343 kJ/m².

摘要： 以玻璃纤维毡为增强骨架，不饱和聚酯树脂为基体材料，制备挡风抑尘板，并对不饱和聚酯树脂与玻璃纤维的配比、玻璃纤维的种类和固化剂、促进剂含量对挡风抑尘板力学性能的影响进行了研究。结果表明，当不饱和聚酯与玻璃纤维毡的质量比达到3∶1时，其拉伸强度和冲击强度都达到最大。高碱、中碱和无碱的玻璃纤维毡增强的挡风抑尘板拉伸强度分别达到55.198，75.249，89.446 MPa，冲击强度分别达到30.699，35.367，41.343 kJ/m²。而无碱玻璃纤维毡其拉伸强度比高碱提高了62%，比中碱提高了18.8%。冲击强度比高碱提高了34.7%，比中碱提高了16.9%。当促进剂质量分数为0.5%、固化剂质量分数为1%时，挡风抑尘板的拉伸强度最大为89.446 MPa，冲击强度最大为41.343 kJ/m²。
