Abstract

The invention discloses a preparation method of a thermoplastic tough foaming adhesive tape. The thermoplastic tough foaming adhesive tape is prepared from a certain amount of thermoplastic elastomer, polyvinyl chloride resin, a filler, a plasticizer, a heat stabilizer, a foaming agent, a foaming promoter and a foam hole regulator through mixing, high-speed stirring, internal mixing and gelatinization, calendering, foaming and embossing treatment. The physical property of the finished thermoplastic tough foaming adhesive tape prepared by the invention meets the standard of artificial leather, and meanwhile, the finished thermoplastic tough foaming adhesive tape has the high elasticity characteristic of an elastomer, so that the quality of the finished thermoplastic tough foaming adhesive tape is remarkably improved, the application range of the finished thermoplastic tough foaming adhesive tape is expanded, the service life is prolonged, better economic benefits are brought to enterprises, and further development of the foaming adhesive tape industry is promoted.

Description

technical field [0001] The invention relates to the field of foamed adhesive tape, in particular to a preparation method of thermoplastic tough foamed adhesive cloth. Background technique [0002] Foam tape has two-layer and three-layer structures. The two-layer structure is divided into adhesive layer (upper layer) and foam layer (lower layer). The three-layer structure is divided into adhesive layer (upper layer), foam layer (middle layer), and adhesive layer (lower layer). . Styrofoam tape has the characteristics of light weight and large volume. At present, in the existing technology, the preparation process of the foamed tape cannot guarantee that the finished tape can maintain excellent elasticity while having good physical properties, resulting in limited application of the foamed tape and restricting the further development of the foamed tape industry . Therefore, the development of a high-elastic thermoplastic foamed adhesive sheet with good physical properties, ...
