Preparation method of heat-resistant high-strength stone plastic floor
The invention belongs to the technical field of building materials and particularly relates to a preparation method of a heat-resistant high-strength stone plastic floor. Crosslinking modified polyvinyl chloride resin and stone powder are used for preparing an intermediate layer plate; a polyvinyl chloride resin crosslinking agent contains specific functional groups; and the introduced ionic groups, polar groups or formed hydrogen bonds can improve the strength of a polyvinyl chloride polymer material, and the crosslinking agent with a specific structure is adopted, so that a specific crosslinking structure is introduced to a polyvinyl chloride macromolecular chain to change the polyvinyl chloride macromolecular chain from a linear structure into a local net structure, the heat resistanceof the polyvinyl chloride can be obviously improved, the heat shrinkage rate is reduced, the comprehensive use performance of the polyvinyl chloride is improved, polyvinyl chloride molecular chains can generate proper partial crosslinking through crosslinking modification, finally the heat shrinkage ratio difference of the polyvinyl chloride and marble powder is reduced, and the heat resistance isimproved. The stone plastic floor prepared by the invention has high mechanical strength, high heat resistance and wide application prospect.
本发明属于建筑材料技术领域，具体涉及一种耐热高强度石塑地板的制备方法。本发明利用交联改性聚氯乙烯树脂与石粉制备成中间层板，所用的聚氯乙烯树脂交联剂含有特定的官能团，引入的离子基团、极性基团或形成的氢键可使聚氯乙烯聚合物材料的强度得道提高，通过采用具有特定结构的交联剂，从而在聚氯乙烯大分子链上引入特定的交联结构，使其由线型结构变成局部网状结构，可以显著地提高聚氯乙烯的耐热性、降低热收缩率、改善其综合使用性能，通过交联改性可以使聚氯乙烯分子链产生适当的部分交联，最终使聚氯乙烯与大理石粉的热收缩比差值减少，耐热性提高；本发明制备的石塑地板，机械强度较高，耐热性较强，有广阔的应用前景。
