Abstract

The invention provides a master batch material, a preparation method of foamed master batch and a preparation method of a foamed material, belonging to the technical field of processing of high polymer materials. The master batch material comprises, by weight, 10-60 parts of carrier resin, 30-80 parts of a foaming agent, 1-5 parts of an auxiliary A and 1-5 parts of an auxiliary B, wherein the foaming agent is composed of an expandable microsphere and a chemical foaming agent, the expandable microsphere is characterized in that a volatile expanding agent serving as a core agent is wrapped in a shell formed by a polymer, the shell is formed by polymerizing a monomer mixture of polymerizable monomers, and the polymerizable monomers are at least one selected from acrylonitrile, acrylate monomers, acrylamide monomers and acrylic acid monomers; the auxiliary A is used for changing the foaming temperature of the foaming agent and promoting foaming of the foaming agent; and the auxiliary B is used for improving the material performance and further reducing a molding shrinkage rate. Through the above treatment scheme, foaming is uniform, and a weight reduction effect is good.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a masterbatch material, a method for preparing a foamed masterbatch and a method for preparing a foamed material. Background technique [0002] The foaming agent can reduce the weight of the material and reduce the production cost. At the same time, the foamed material has the advantages of good toughness, cushioning, heat insulation, weather resistance, resilience, and sound absorption. However, the existing foaming materials have problems such as dust flying, cell series connection, and cell size unevenness, and the prepared plastic masterbatch has the characteristics of easy dispersion and high content. The foaming function masterbatch is imperative. [0003] In patent CN110734597A, citric acid derivatives are used as a foaming agent to prepare foam masterbatches for polypropylene molding. The resulting product has uniform cells, but the cost is high and t...
