Problems solved by technology

However, these two kinds of coating processes are complicated, and the construction period is long, which may easily lead to poor compatibility of the entire coating system.
The existing water-based bottom-surface all-in-one paint mainly has the following deficiencies: neutral salt spray resistance, water resistance, artificial aging resistance, etc. are not up to the standard, the surface is not smooth and smooth, and its comprehensive performance needs to be further improved. Therefore, the invention People are committed to solving the above problems through long-term research and long-term practice

Abstract

The invention discloses water-based single-component primer-topcoat integrated paint which comprises the following raw material components by weight: 50-60 parts of water-based carbon-titanium hyperbranched silicone acrylic resin; 0.6 part of a cosolvent, 12-20 parts of distilled water, 0.2 part of a pH regulator, 0.1 part of an antifoaming agent, 1 part of a dispersant, 1-2 parts of a coalescingagent, 0.4-0.8 part of an anti-flash-rust additive, 0.4-0.8 part of an antirust pigment, 13-18 parts of a pigment, 5 parts of a filler and 1 part of a thickener are mixed and stirred to prepare the paint. The water-based single-component primer-topcoat integrated paint has the characteristics of high drying speed, high corrosion resistance, low VOC (volatile organic compound), simple constructionoperation, high one-time film-forming property and the like.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a water-based one-component bottom-surface-in-one paint and a preparation method thereof. Background technique [0002] Today, there are mainly two types of traditional anti-corrosion coating systems in China, which are primer + primer + top coat composite anti-corrosion coating system or primer + top coat composite anti-corrosion coating system. Among them, the primer mainly protects the surface of the substrate, and at the same time provides good adhesion and anti-corrosion performance; the primer mainly plays the role of repairing and filling, making the surface of the substrate smooth, which is beneficial to paint coating, and the topcoat mainly plays a decorative role. Function, with high hardness, high wear resistance, high chemical properties and so on. However, these two kinds of coating processes are complicated, and the construction period is long, which easily l...
