Abstract

The invention relates to a thin film prepared from inorganic mineral powder. The thin film is characterized by being prepared from the following components in percentage by weight: 53%-60% of inorganic mineral powder, 20%-25% of polyurethane, 5%-10% of a polyurethane elastomer, 10%-15% of polyurethane fibers, 3-5% of a dispersing agent and 1%-2% of a processing aid; and the thickness of the thin film is 30-50 microns. According to the technical scheme, the thin film is creatively prepared from the inorganic mineral powder, polyurethane, the dispersing agent, the aid and the fiber by virtue of a film blowing machine and is taken as a base material of an adhesive tape for replacing a traditional base material, so that the raw material cost of the adhesive tape is greatly lowered, and the thin film is degradable.

Description

technical field [0001] The invention relates to the technical field of polymer material modification and processing, in particular to a film made of inorganic mineral powder. Background technique [0002] In the prior art, the adhesive tape is usually based on BOPP biaxially oriented polypropylene film, and the pressure-sensitive adhesive emulsion is uniformly applied after heating to form an adhesive layer. Adhesive tape is an indispensable product in light industry enterprises, companies, and personal life; the main component of the above-mentioned pressure-sensitive adhesive emulsion is butyl ester. [0003] The Chinese patent with the authorized announcement number CN1105636C, the patent name is the manufacturing method of environmental protection paper, which discloses a kind of environmental protection paper and the method of producing the environmental protection paper, which mainly uses limestone mineral resources as the main raw material and high molecular polymer a...
