Abstract

The invention belongs to the technical field of wood-like plastics and relates to a frosted polyvinyl chloride wood-like master batch. The frosted polyvinyl chloride wood-like master batch comprises afrosted filler, polyvinyl chloride resin, a plasticizer, a first dispersing agent, a coupling agent and a first wood-like color pigment; the frosted filler comprises biomass powder, thermosetting resin, a second dispersing agent and a second wood-like color pigment. With the frosted polyvinyl chloride wood-like master batch of the invention adopted, the problem of single texture of wood-like plastic products in the prior art is solved. The polyvinyl chloride resin is added into the frosted filler in the polyvinyl chloride wood-like master batch; the decomposition temperature of the thermosetting resin is far higher than the molding temperature of the polyvinyl chloride resin, the surface energy of the cured thermosetting resin is lower, and the dispersity of the cured thermosetting resinis higher than that of a common inorganic filler, so that the thermosetting resin can be uniformly dispersed in the master batch and cannot be decomposed, and the frosted feeling of the master batch is improved.

Description

technical field [0001] The invention relates to the technical field of imitation wood plastics, in particular to a polyvinyl chloride imitation wood masterbatch with frosted texture and a preparation method thereof. Background technique [0002] With the popularity of plastic products in various industries and fields, the invention and research of functional plastic masterbatches have become more and more important. In specific applications, metal, wood, stone and other natural materials can be used to have their appearance Substituting high-quality plastic products can not only reduce costs, but also have the advantages of strong plasticity, corrosion resistance, and high strength. [0003] Polyvinyl chloride (PVC) is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copoly...
