Problems solved by technology

After many years of on-the-spot follow-up research by the inventor, it was found that after the galvanized pipe was painted with this kind of paint, serious paint film peeling would occur within 1-2 years, and then it needed to be repainted, and the construction surface needed to be re-polished during the refurbishment process. , resulting in a huge waste of
At present, there are water-based paints for metals on the market, but this type of water-based paint still has the problem of poor adhesion to galvanized pipes

Embodiment 1

[0041] A water-based anti-rust white paint, comprising the following components, the weight percentage of each component is: water-based acrylic resin: 29%, acrylic modified water-based epoxy ester resin: 8%, composite aluminum tripolyphosphate: 12% ; Calcium carbonate: 5%; Mica powder: 5%; Adhesion promoter: 0.8%; Coating agent: 4%; Anti-flash rust agent: 1.2%; Wetting agent: 0.3%; defoamer: 0.5%; fungicide: 0.3%; PH regulator: 0.2%; thickener: 1.5%, water: 10.6%; water-based titanium white paste: 21%

[0042] Follow the steps below to prepare:

[0043] Put the above-mentioned dispersant, wetting agent, water and 50% defoamer into a high-speed mixing container, stir evenly at a slow speed, and then add composite aluminum tripolyphosphate, calcium carbonate, and mica powder at a constant speed while stirring at a high speed. Disperse until the scraper fineness is below 30 microns;

[0044] 2) Mix the above silicone-modified water-based acrylic resin, acrylic-modified water-b...

Abstract

The invention relates to water-based paint applied to galvanized pipes and a preparation method of the water-based paint. The water-based paint comprises water-based acrylic resin, acrylic acid modified water-based epoxy ester resin, water, a dispersing agent, a wetting agent, a leveling agent, an antifoaming agent, aluminum triphosphate, calcium carbonate, mica powder, a bactericide, a thickener, a coalescing agent, an adhesion promoter, an anti-flash-rust agent and a pH regulator. Compared with the prior art, the water-based paint has the beneficial effects of strong adhesive force and high weather resistance of a paint film when being used for coating a galvanized pipe.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, in particular to a water-based paint applied to galvanized pipes and a preparation method thereof. Background technique [0002] Galvanized pipe is a common alloy pipe, which has the characteristics of corrosion resistance and not easy to rust. It was widely used as a water delivery pipe for tap water pipe network in the early days, and now it is mostly used for gas pipe network, heating pipe, fire sprinkler pipe, or not as a pipe Function, directly as the material of the protective railing. The specific application scenarios of galvanized pipes In order to meet the requirements of relevant administrative regulations, the specific pipe network must be color-coded. For example, the gas pipe network must be yellow, the fire sprinkler pipe network must be red, and most of the coloring of galvanized pipes is through painting. Paint achieved. Although the surface of the galvanized pipe has a ...
