High-hardness polyethylene floor and preparation method thereof

[0014] Example 1

[0015] The high-hardness polyethylene floor is composed of the following materials by weight: 25 parts of polyvinyl chloride resin SG7 type; 55 parts of polyvinyl chloride resin SG8 type; 12 parts of wood powder; 30 parts of heavy calcium; 40 parts of floor recycling materials ; 2.4 parts of calcium stearate; 5 parts of foaming regulator YF-530; 0.4 part of ADC foaming agent; 0.9 part of DC foaming agent; 0.25 part of stearic acid; 0.4 part of oxidized polyethylene wax, internal lubricant HLD- 0.5 part of 60; 0.5 part of external lubricant G31; 3 parts of toughening agent EVA, of which wood flour and heavy calcium need to be activated before use.

[0016] The preparation method of the high-hardness polyethylene floor, the specific steps are as follows:

[0017] Add the polyvinyl chloride resin, wood flour, heavy calcium and floor recycling materials to the hot mixing pot and heat it to 40-55 °C, then add other raw materials to the hot mixing pot, mix evenly an
