PVC-PP (polyvinyl chloride-polypropylene) foamed composite floor material

Abstract

The invention discloses a PVC-PP (polyvinyl chloride-polypropylene) foamed composite floor material, belonging to the field of floor. The PVC-PP foamed composite floor material is prepared from the following components in parts by weight: 100 parts of PVC, 40-50 parts of PP, 80-90 parts of bamboo powder, 7-11 parts of paraffin, 0.1-0.6 part of stearic acid, 15-28 parts of superfine calcium carbonate, 5-9 parts of epoxy soybean oil, 1-3 parts of polyacrylate, 0.2-1 part of barium stearate, 2-4 parts of calcium zinc composite stabilizer and 0.5-1.5 parts of foaming agent. The foamed composite floor material is prepared by using the PVC and PP as the plastic raw materials and adding the plant fiber bamboo powder, and has the characteristics of accessible raw materials and low price, so the prepared composite floor has the advantages of the PVC and PP plastics and the plant fiber bamboo powder. The composite material has higher shock strength and higher buckling strength.

Description

technical field [0001] The invention belongs to the field of floor production, in particular to a PVC-PP foam composite floor material. Background technique [0002] Composite flooring materials are composite materials made of wood or cellulose and plastics. Composite flooring has the properties of different materials. Because waste can be reused, it can effectively reduce environmental pollution and protect forest resources. Due to the compression of plant fibers during processing, the density of the product is greater than that of ordinary wood. The addition of fibers reduces the toughness of plastics, and the low bonding force between hydrophilic fibers and hydrophobic plastics leads to the impact strength and resistance of composite materials. Mechanical properties such as bending strength are inferior to pure plastics. The foamed composite material is formed by mixing raw materials in proportion and introducing very small cells into the composite material through the a...

AI Technical Summary

Problems solved by technology

The good internal cell structure can passivate the crack tip, prevent the crack from expanding, and overcome the shortcomings of half of the composite material, such as high brittleness, weak impact strength and low growth rate

PVC, PP and bamboo powder are used to synthesize composite flooring materials to overcome the compatibility problems of plant fibers and plastics and the research on mechanical properties is rare
