Problems solved by technology

And its solvent-based paint is the paint we are familiar with. Not only is it harmful to the air environment and on-site painting operators, but there are still organic compound residues (formaldehyde, benzene, xylene, etc.) within 3 months of paint spraying. During the solvent volatilization process, there will also be potential hazards to factory employees who will operate large machinery and equipment in the future

Abstract

The invention discloses environment-friendly water-based acrylic acid modified alkyd protective paint used for spraying mechanical equipment, and a preparation method of the protective paint. The environment-friendly water-based acrylic acid modified alkyd protective paint used for spraying the mechanical equipment comprises the following components in parts by weight: 10-12 parts of water-based alkyd resin, 40-47 parts of acrylic emulsion,20-25 parts of water, 1.8-2.4 parts of a pH (potential of hydrogen) regulator, 0.3-0.6 parts of a dispersant, 0.1-0.15 parts of a defoaming agent, 4.0-5.0 parts of rutile titanium dioxide, 0.4-0.5 parts of carbon black, 5-8 parts of compound zinc phosphate, triphosphoric acid, barium sulfate, talcum powder, iron-titanium compound powder, an anti-settling agent, a film forming assistant, a flash-rust preventive, a base material wetting agent and a thickening agent. The protective paint has excellent chemical properties such as corrosion resistance and water resistance, and is high in drying rate, excellent in low-temperature film forming effect, high in plumpness and good in weather resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly water-based acrylic modified alkyd protective paint for spraying mechanical equipment and equipment and a preparation method thereof. Background technique [0002] As we all know, there are many kinds of large-scale mechanical equipment, and mechanical equipment is composed of driving device, speed change device, transmission device, working device, braking device, protective device, lubrication system, cooling system and other parts. It is basically popularized in all aspects of large-scale industrial equipment and plays a major role in the modernization of the national economy. Especially with lathes, CNC machine tools, and engine casings as the main direction, the paint film has high requirements, requiring extremely high adhesion, hardness, and aging resistance, and even some parts have high temperature resistance and moisture resistance to the co...
