废胶粉和锯末对废纸浆性能的影响

试验研究废胶粉和锯末对废纸浆性能的影响。结果表明：废胶粉/废纸浆、锯末/废纸浆和废胶粉/锯末/废纸浆复合材料的物理性能提高，且废胶粉/废纸浆复合材料的物理性能优于废胶粉/锯末/废纸浆复合材料，因此以废胶粉改性废纸浆效果较好。废胶粉/废纸浆复合材料的最佳配方为：废纸浆 100（干基计），废胶粉 8，防老剂D 0.2，硫黄 0.2，促进剂M 0.2；最佳固化条件为150 ℃/10 MPa×30 min。此时材料表面比较光滑，结构紧密，排列比较均匀，废胶粉与废纸浆的相容性较好。;The influence of waste rubber powder and sawdust on the physical properties of waste paper pulp was investigated.The results showed that，the physical properties of waste rubber powder/waste paper pulp，sawdust/waste paper pulp and waste rubber powder/sawdust/waste paper pulp composite were enhanced，and the physical properties of waste rubber powder/waste paper pulp composite were superior to those of waste rubber powder/sawdust/waste paper pulp composite.So the effect of waste rubber powder on the modification of waste paper pulp was better.The optimum formulation of waste rubber powder/waste paper pulp composite was as follows：waste paper pulp 100（calculated on dry material），waste rubber powder 8，antioxidant D 0.2，sulphur 0.2，accelerator M 0.2.The optimum cure condition was 150 ℃/10 MPa×30 min.Under this condition，the surface of waste rubber powder/waste paper pulp composite was smooth，the structure was compact and uniform，and the arrangement was even，and the compatibility between waste rubber powder and waste paper pulp was good
