Embodiment 1

[0014] Take 50 kg of styrene-acrylic emulsion with a solid content of 48%, 16 kg of aluminum tripolyphosphate, 16 kg of iron oxide, 10 kg of calcium carbonate, 4 kg of film-forming aid, 3.5 kg of dispersant, 1.1 kg of corrosion inhibitor, and anti-settling agent. 0.8 kg is prepared. First, the pigments, fillers, dispersants, film-forming aids, anti-settling agents and water are mixed and stirred evenly, and then ground to a fineness of <60μm in a conical grinder to obtain color paste, and then add styrene-acrylic emulsion. , film-forming aids and corrosion inhibitors, the products are obtained by dispersing them evenly. The non-toxic anti-rust paint for hydraulic components is a water-based anti-rust latex paint with styrene-acrylic emulsion as the main base material and non-toxic anti-rust pigments. , Aging resistance, chemical corrosion resistance, high adhesion and other advantages.

Embodiment 2

[0016] Take 53 kg of styrene-acrylic emulsion with a solid content of 49%, 8.8 kg of aluminum tripolyphosphate, 12 kg of iron oxide, 13 kg of calcium carbonate, 3.7 kg of film-forming aid, 3.4 kg of dispersant, 1.2 kg of corrosion inhibitor, and anti-settling agent. 0.6 kg is prepared. First, the pigments, fillers, dispersants, film-forming aids, anti-settling agents and water are mixed and stirred evenly, and then ground in a conical grinder to a fineness of <60 μm to obtain color paste, and then add styrene-acrylic emulsion , film-forming aids and corrosion inhibitors, the products are obtained by dispersing them evenly. The non-toxic anti-rust paint for hydraulic components is a water-based anti-rust latex paint with styrene-acrylic emulsion as the main base material and non-toxic anti-rust pigments. , Aging resistance, chemical corrosion resistance, high adhesion and other advantages.

Embodiment 3

[0018] Take 55 kg of styrene-acrylic emulsion with a solid content of 50%, 7 kg of aluminum tripolyphosphate, 10 kg of iron oxide, 14 kg of calcium carbonate, 3.3 kg of film-forming aid, 3 kg of dispersant, 1.3 kg of corrosion inhibitor, and anti-settling agent. 0.4 kg is prepared. First, the pigments, fillers, dispersants, film-forming aids, anti-settling agents and water are mixed and stirred evenly, and then ground in a conical grinder to a fineness of <60μm to obtain color paste, and then add styrene-acrylic emulsion , film-forming aids and corrosion inhibitors, the products are obtained by dispersing them evenly. The non-toxic anti-rust paint for hydraulic components is a water-based anti-rust latex paint with styrene-acrylic emulsion as the main base material and non-toxic anti-rust pigments. , Aging resistance, chemical corrosion resistance, high adhesion and other advantages.

Abstract

The invention discloses a nontoxic rustproof coating for a hydraulic element. The nontoxic rustproof coating is composed of, by weight, 50-55 parts of styrene-acrylic emulsion, 7-16 parts of aluminumtripolyphosphate, 10-16 parts of iron oxide, 10-14 parts of calcium carbonate, 3.3-4 parts of film forming aid, 3-3.5 parts of dispersant, 1.1-1.3 parts of corrosion inhibitor and 0.4-0.8 part of anti-settling agent. The nontoxic rustproof coating is a waterborne rustproof latex coating formed by combining the styrene-acrylic emulsion serving as a main base material with nontoxic rustproof pigmentand has the advantages of being nontoxic, resistant to aging and chemical corrosion and high in adhesiveness.

Description

technical field [0001] The invention relates to the technical field of anti-rust of hydraulic components, in particular to a non-toxic anti-rust paint for hydraulic components. Background technique [0002] Hydraulic components are essential parts of various mechanical equipment. In order to ensure the service life of hydraulic components, anti-rust coatings are generally sprayed on the surface of hydraulic components. Most of the anti-rust coatings currently used in the industry are solvent-based. In addition to a large amount of organic solvents, this type of anti-rust paint also contains many toxic pigments, which cause pollution to the human body and the environment, and are not safe. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a non-toxic anti-rust paint for hydraulic components, so as to solve the problem that the solvent-based anti-rust paint in the prior art contains a large amount of organic solvents and toxic pigments, wh...
