Water-based environment-friendly radiator paint and preparing method thereof

Abstract

The invention discloses water-based environment-friendly radiator paint and a preparing method thereof. The water-based environment-friendly radiator paint comprises, by weight, 20 parts to 25 parts of water-based self-crosslinking acrylate emulsion, 10 parts to 15 parts of polyurethane emulsion, 6 parts to 8 parts of passivation liquid, 5 parts to 7 parts of acrylic-silicone emulsion, 4 parts to 6 parts of chitosan, 5 parts to 7 parts of adhesion pigment, 0.6 part to 0.8 part of defoaming agents, 0.03 part to 0.05 part of flatting agents, 12 parts to 15 parts of plant water-based color paste, 0.4 part to 0.6 part of cellulose acetate, 0.5 g / L to 0.7 g / L of penetrating agents JFC, 0.2 part to 0.5 part of pentachlorodiphenyl and 100 parts of deionized water. By means of the water-based environment-friendly radiator paint and the preparing method, the water paint spraying film forming speed is increased, and a passive film is good in corrosion resistance, low in porosity, rich in plant ingredient, nontoxic, environmentally friendly and low in smell, and has the certain antibacterial effect and the certain fireproof performance; the surface adhesive force of the radiator paint is improved, the luster is bright, the crack resistance is improved, the workpiece bonding performance of the environment-friendly radiator paint can be improved, the effect that repeated adhesion of the surface of the radiator paint can be avoided after the radiator paint is dried is achieved, and the excellent water resistance is achieved.

Description

technical field [0001] The invention belongs to the technical field of water paints, and in particular relates to water-based environmental protection radiator paints and a preparation method thereof. Background technique [0002] Cast iron radiators have gradually withdrawn from the market stage. New radiators such as steel radiators and copper-aluminum composite radiators are superior to cast iron radiators in terms of material and manufacturing process, and have become the most mainstream radiators in the market. The outer surface of the radiator should adopt electrostatic spraying process after good pretreatment. The surface of the paint film should be smooth, flat and uniform, without air bubbles, accumulation, flow and spray leakage; the thickness of the primer should not be less than 15μm, and the thickness of the paint film should not be less than 60μm; the adhesion of the paint film should meet the requirements of grade 1-3 stipulated in GB / T1720; the impact resista...

Problems solved by technology

[0004] The solvents used in the paint are all volatile organic compounds that are harmful to the human body, causing the paint to smell unpleasant and pungent, and long-term inhalation will cause damage to the human respiratory system and nervous system, causing irreversible health damage to users

When some radiators are painted after being used for a period of time, the residue on the surface will hinder the uniformity of paint coating, so the passivation of the workpiece surface will seriously affect the coating effect
