Problems solved by technology

[0009] The performance of damping coatings generally includes sound insulation and shock absorption, heat insulation and sealing. It can be directly sprayed on the surface of the substrate, which has certain advantages. The disadvantage is that it does not have sufficient mechanical properties and the compression resistance is not ideal.

Abstract

The invention discloses an electronic damping paint and a preparation method thereof, and belongs to the technical field of paints. The paint comprises the following components in parts by weight: 25 to 40 parts of epoxy resin, 15 to 25 parts of polyurethane, 3 to 7 parts of white carbon black, 5 to 10 parts of glass fiber, 3 to 10 parts of nano calcium carbonate, 4 to 9 parts of polyalkyl acrylate, 5 to 10 parts of polyamide, 5 to 12 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, and 15 to 32 parts of water. The preparation method comprises the following steps: (1) weighing; (2) grinding; (3) mixing in a static mixer; (4) indoor standing for 24 to 48 hours to obtain the electronic damping paint. Dual resins are adopted as the damping resin, nano calcium carbonate is taken as the nano filling material to enhance the damping effect of coating, at the same time the coating film-forming effect is good, the electronic elements can be well enclosed by the paint, thus the electronic elements can be better protected, and moreover, the paint has a damping and noise-reducing effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an electronic damping coating and a preparation method thereof. Background technique [0002] Electronic coatings are coating compositions for electronic components or equipment. With the advancement of technology, the types and quantities of electronic components and equipment are increasing, and the volume is getting smaller and smaller, and the design is getting more sophisticated. This refined development trend, on the one hand, greatly meets people's use needs, and on the other hand, drives the refined development trend in many fields. [0003] Electronic coatings are a refined field developed to meet the needs of the electronics industry. Different from general coatings, coatings in the electronic field have stricter performance requirements for coating compositions. [0004] First of all, electronic coatings are generally sprayed, so the preparation process needs to be ...
