Problems solved by technology

The traditional PVC coil is mainly inorganic filler reinforced PVC, which has high PVC content, high density and high cost
[0003] A large amount of waste PVC cable materials and plant fibers are produced in our country every year. Waste plastics are not easy to decompose and produce toxic substances when decomposed; burning waste plant fibers will cause air pollution

Abstract

The invention discloses a PVC micro-foaming wood-plastic coiled material, including the following materials by weight portion:100 portions of PVC, 70-80 portions of waste vegetable fibers, 10-30 portions of CaCO3, 1-4 portions of coupling agent, 2-8 portions of heat stabilizer, 3-9 portions of lubricant, 7-12 portions of toughening agent, 3-7 portions of plasticizer, 0.6-1.2 portions of composite foaming agent and 2-3 portions of titanium pigment powder. Compared with the prior art, the composite material prepared by the method has high toughness, the disadvantages of high resin content, little filler and high cost of common PVC coiled materials are avoided. The coiled materials can be used as the coating materials of indoor floor, peripheries and walls with sophisticated shapes.

Description

technical field [0001] The invention belongs to a micro-foamed wood-plastic coil and a production method thereof, in particular to a PVC micro-foamed wood-plastic coil and a production method thereof. Background technique [0002] PVC micro-foamed wood-plastic coil has the advantages of good elasticity, high elongation, small shrinkage, convenient construction, beautiful appearance, good waterproof effect, and long service life. The traditional PVC coil is mainly inorganic filler reinforced PVC, which has high PVC content, high density and high cost. [0003] my country produces a large amount of waste PVC cable materials and plant fibers every year. Waste plastics are not easy to decompose and produce toxic substances when decomposed; waste plant fibers will cause air pollution when burned. Contents of the invention [0004] The first technical problem to be solved by the present invention is to provide a PVC micro-foamed wood-plastic coiled material that uses plant fibe...
