紫外线光固化竹粉/丙烯酸酯复合材料的性能
Physical mechanical properties of bamboo powder/acrylate composite prepared by ultraviolet curing technology
摘要
Abstract
To improve the making efficiency of wood-plastics composite (WPC) and promote energy conservation, bamboo powder (BP)/acrylate composites were preparing through ultraviolet (UV) curing technology which can further enrich and perfect the processing technology of WPC.The influences of BP content on the dynamic mechanical properties, flexural properties and water absorption of BP/acrylate composite were studied using a material testing machines and dynamical thermal mechanical analyzer (DMA).The results showed that BP and acrylate can form crosslinking networks, improving physical properties of composite.Flexural property of composite increased with BP content increase, and got to the maximum at of 20% of BP, and then it reduced.DMA results showed that storage modulus of composite increased as BP content increased and decreased when over 20% of BP.The glass transition temperature of composite increased from 84 ℃ to 105 ℃ owing to the addition of BP.BP/acrylate composite had excellent water resistance since the water absorption of composites changed a little although composites were soaked in boiling water for 1.5 h.BP/acrylate composites with 20% of BP had better physical properties: flexural strength was 39.4 MPa;flexural modulus was 2 800 MPa;water absorption was 5.95%.关键词
