Environment-friendly polypropylene floor and process thereof
The invention relates to an environment-friendly polypropylene floor which is prepared from the following formula in parts by weight: 20-80 parts of polypropylene, 0.5-5 parts of an antioxidant, 0.05-5 parts of a flame retardant, 20-80 parts of calcium carbonate, 0.5-3 parts of a silane coupling agent, 0.1-0.5 part of a light stabilizer, 0.1-5 parts of toner, 5-10 parts of fly ash, 0.3-1.5 parts of nano zinc oxide particles and 3-5 parts of ASP starch. The environment-friendly polypropylene floor is prepared by the steps: mixing the raw materials according to the weight ratio; carrying out hot mixing on the mixed material by adopting a high-speed mixer, wherein the hot mixing temperature is 80-120 DEG C; carrying out cold mixing on the mixture after hot mixing, wherein the cold mixing temperature is 40-60 DEG C; carrying out heating extrusion on the cold-mixed mixture through an extruder, and carrying out extrusion molding in a sheet die head; extruding and shaping a formed sheet through a calender; carrying out surface UV tempering treatment on the sheet, firstly putting the sheet into hot water with the temperature of 50-80 DEG C and then putting into cold water with the temperature of 10-25 DEG C; and slitting, grooving and packaging. The material is environmentally friendly and has high impact strength, wear resistance and scratch resistance, and the shrinkage rate is reduced.
本发明涉及一种环保型聚丙烯地板，包括以下配方制成：聚丙烯20‑80份，抗氧剂0.5‑5份，阻燃剂0.05‑5份，碳酸钙20‑80份，硅烷偶联剂0.5‑3份，0.1‑0.5份的光稳定剂，0.1‑5份的色粉，5‑10份的粉煤灰，纳米氧化锌颗粒0.3‑1.5份，ASP淀粉3‑5份。将原材料按照重量配比进行混料；采用高速混合机对混料进行热混，热混温度为80‑120℃；将热混后的混料进行冷混，冷混温度为40‑60℃；将冷混后的混料通过挤出机进行加热挤出，进入片材模头挤出成型；将成型后的片材通过压延机进行挤压定型；将片材进行表面UV回火处理，先放入温度为50‑80℃的热水，随后放入10‑25℃的冷水；分切开槽包装。本发明不仅环保，而且有较高的冲击强度，耐磨性和耐刮性，并且降低了收缩率。
