Abstract

The invention discloses a pressure-resistant and stretch-proof composite plastic terrace coating material and a preparation method thereof. The material comprises 20-28 parts of polyvinyl chloride, 15-25 parts of polyurethane, 7-15 parts of poly(9-amino nonanoic acid), 4-7 parts of ethoxy modified trisiloxane, 6-12 parts of simethicone, 5-10 parts of hydroxypropyl methyl cellulose, 3-7 parts of calcium metasilicate, 4-10 parts of aluminum nitride, 3-6 parts of tri-isobutyl phosphate, 2-5 parts of antioxidant 1076 and 3-6 parts of silane coupling agent KH-602. The preparation method includes the following steps of firstly, ball-milling the calcium metasilicate and the aluminum nitride through a ball mill; secondly, mixing the components in a high-speed mixer; thirdly, fusing and extruding the evenly-mixed plastic terrace coating material on a double-screw extruder; fourthly, granulating the material to prepare the pressure-resistant and stretch-proof composite plastic terrace coating material.

Description

technical field [0001] The invention belongs to the field of plastic materials, and relates to a plastic material and a preparation method thereof, in particular to a pressure-resistant and tensile-resistant composite plastic floor material and a preparation method thereof. Background technique [0002] The floor is the part where the ground floor rooms of the building are in contact with the lower soil layer. It bears the ground load of the low floor rooms and must have good wear resistance, moisture resistance, water resistance, and thermal insulation properties. Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances.
