Three-layer co-extrusion preparation technology for plastic floor

Abstract

The invention discloses a three-layer co-extrusion preparation technology for a plastic floor. The plastic floor comprises an upper surface layer, a middle layer and a lower surface layer. The middle layer comprises, by weight, 50-60 parts of polyvinyl chloride, 30-40 parts of calcium carbonate, 0.5 part of a foaming agent, 3-5 parts of a stabilizer, 2-3 parts of a lubricant, 3-6 parts of polyphenyl granules, 4-8 parts of crushed crude pearlite, 10-13 parts of polyurethane, 2-5 parts of ammonium dihydrogen phosphate and 2-3 parts of accessories. The upper surface layer and the lower surface layer comprise, by weight, 30-40 parts of heat-resisting polyethylene, 30-35 parts of calcium carbonate, 5 parts of a stabilizer, 3 parts of a lubricant, 10-13 parts of rock wool powder, 4-6 parts of nano-zinc oxide powder, a silver ion antibacterial agent, 2-3 parts of mica powder and 3-5 parts of accessories. The preparation technology includes the steps of burdening, mixing, heating extrusion, cooling, shaping and floor discharging as well as processing of the plastic floor surface. According to the three-layer co-extrusion preparation technology for the plastic floor, design is reasonable, the production steps are simple, and the plastic floor produced through the technology is tight in connection, long in service life and good in elastic comfortable sensation.

Description

technical field [0001] The invention relates to the production technology of the base plate, in particular to a three-layer co-extrusion preparation process of the plastic plate. Background technique [0002] The flame retardancy of wooden floors is poor. At the same time, blisters during the production period are prone to breed bacteria and the practical life will be shortened. Ceramic tiles are relatively heavy. At the same time, heavy and hard objects falling from a high place will easily cause the bottom plate to break. Plastic floors are light, waterproof and Convenience of construction has become people's first choice of decoration materials. Most of the existing technologies are produced by pressing technology, but the connection between layers of the pressed bottom plate is not tight, and the glue will overflow during pressing, which needs to be removed. High-quality glue makes the production process more cumbersome, and the quality of the floor produced is not high....

Plastic floors are light, waterproof and Convenience of construction has become people's first choice of decoration materials. Most of the existing technologies are produced by pressing technology, but the connection between layers of the pressed bottom plate is not tight, and the glue will overflow during pressing, which needs to be removed. Glue, so that the production process is more cumbersome, the quality of the floor produced is not high
