Abstract

The invention relates to a water-soluble conducting polyaniline static-free damping paint and a preparation method thereof, belonging to a static-free damping paint. The water-soluble conducting polyaniline static-free damping paint contains the following raw materials in portions by weight: 20-40 portions of basic materials commixed by styrene-acrylic emulsion and water-based elastic acrylic emulsion dedicated for the water-based damping paint; 20-50 portions of fillers being several ones of lamellar mica powder, precipitated calcium carbonate, zinc phosphate, talc powder, titanium pigment, precipitated barium sulfate and silica sand; 25-50 portions of static-free fillers being water-soluble conducting polyaniline solution; 1-5 portions of fire retardants; and 2-6 portions of film forming assistants. The invention has the advantages that water-soluble emulsions are used as basic materials to ensure that the paint has such features as no position, no smell, incombustibility, no environmental pollution and easy construction; excellent damping effect and vibration-absorption effect are guaranteed; besides, as water-soluble conducting polyaniline solution is used as the static-free filler, the water-soluble conducting polyaniline static-free damping paint has the static-free function not available in the damping paint.

Description

technical field [0001] The invention belongs to an antistatic damping paint. Background technique [0002] As one of the main products of conductive polymer materials, polyaniline has developed rapidly in the process of industrialization, and its application range is very wide. At present, it has been widely used in the fields of electronics, chemical industry, metal anticorrosion, electromagnetic shielding, and luminescent materials. Anti-static damping materials have a huge market in my country, especially with the rapid development of my country's electronics industry, the demand for damping materials for anti-static boxes and shells of electronic products continues to increase. It is particularly worth noting that the market has increasingly high requirements on the quality of anti-static damping materials to meet the needs of high-precision electronic product outer boxes and casings. At present, the antistatic damping materials produced on the market in our country al...
