Binder for artificial stone and preparation method thereof
The invention belongs to the technical field of waste plastic recycling, and particularly relates to a binder for artificial stone and a preparation method of the binder. The adhesive is prepared by depolymerizing waste PET (Polyethylene Terephthalate) in a catalytic alcoholysis manner of a catalyst, carrying out polycondensation on an alcoholyzed miscellaneous material-containing mother solution containing oligomers, monomers, solvents and the like generated by depolymerizing PET, and diluting with a diluent, and the performance of the adhesive can be regulated and controlled by controlling the process conditions of depolymerization and polycondensation. The binder for the artificial stone comprises the following components in percentage by mass: 70-90% of unsaturated polyester resin; 5-30% of residual organic solution; 0.5 to 5% of an organic insoluble substance; and the balance of inorganic insoluble substances. The prepared binder is excellent in performance, the preparation method is simple, the production cost is low, and the binder can be used for industrial large-scale production, so that recovery and high-valued reutilization of waste plastics are realized.
本发明属于废弃塑料回收再利用技术领域，具体涉及一种人造石用粘结剂及其制备方法。该粘结剂由废弃PET经催化剂催化醇解的方式解聚、醇解后的内含PET解聚生成的低聚物和单体、溶剂等的含杂料母液重新缩聚、再经稀释剂稀释而成，可通过控制解聚、缩聚的工艺条件来调控粘结剂性能。按质量百分比，人造石用粘结剂组成如下：不饱和聚酯树脂70～90％；残留的有机溶液5～30％；有机类不溶物0.5～5％；无机类不溶物为余量。本发明制得的粘结剂性能优异，其制备方法简单，生产成本低，可用于工业化大规模生产，从而实现废塑料的回收与高值化再利用。
