Abstract

The invention relates to the technical field of coatings, and provides a graphene-based modified inorganic zinc silicate shop primer and a preparation method thereof. When the coating has a low metal zinc content, its protection period can exceed that of inorganic silicic acid with high zinc content. Zinc workshop primer saves the consumption of metal zinc resources, reduces the generation of harmful zinc fog during cutting and welding, and has good storage stability, construction performance and high-speed cutting and welding performance. Divided into two components, the first component is composed of the following raw materials in parts by weight: 0.1-2 parts of auxiliary film-forming resin, 20-30 parts of solvent, 0.1-1 part of dispersant, 20-50 parts of filler, 20-20 parts of zinc powder 30 parts, 1-2 parts of anti-sedimentation agent, 0.1-1 part of graphene; the second component is composed of the following raw materials in parts by weight: 30-50 parts of ethyl silicate, 0.01-0.1 parts of catalyst, deionized water 3 to 5 parts, 45 to 65 parts of solvent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a graphene-modified inorganic zinc silicate shop primer and a preparation method thereof. Background technique [0002] Inorganic zinc silicate shop primer is a steel pretreatment primer with fast drying speed and excellent corrosion resistance, which can meet the rapid cutting and welding process of the assembly line, so it is widely used in the temporary protection of steel in manufacturing industries such as ships and steel structures And maintenance, inorganic zinc silicate shop primer is currently the largest variety of shop primer. According to the requirements of the environment where the steel or component is located, and the content of metal zinc in the inorganic zinc silicate shop primer, the protection period of the 15-20 micron coating is generally 3-12 months. When the coating metal zinc content is high, The coating protection period is prolonged, but the toxic zin...
