Problems solved by technology

[0003] At present, most of the guardrails mainly use solvent-based industrial coatings, which release volatile organic compounds (Volatile Organic Compounds, VOC) during production and use, resulting in pollution. At present, they have become the main source of pollution in cities after cars, endangering the human body healthy
Water-based coatings are environmentally friendly coatings, but traditional water-based coatings have disadvantages such as insufficient film hardness, easy scratches, poor chemical resistance, low solid content, and thin film thickness.

Abstract

The invention relates to a stain-free water-based industrial guardrail paint, an acrylic polyurethane emulsion is selected and matched with water-based epoxidized soybean oil modified alkyd resin anda propylene glycol ethyl ether film-forming agent, the obtained paint has excellent wear resistance and hardness, a polyurea curing agent is used, and the paint has the ultra-fast drying characteristic and has excellent water resistance and solvent resistance; and self-cleaning performance is good. In order to further improve the self-cleaning performance of the paint, polyethylene glycol is further added, although the proportion of polyethylene glycol in a paint film is not high, polyethylene glycol is matched with a polyurea curing agent, the water contact angle of the paint film can be remarkably increased, and therefore the better hydrophobic effect is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial paints, in particular to a non-staining water-based industrial guardrail paint. Background technique [0002] Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. Industrial guardrails are mainly made of steel, which has a lot of contact with personnel, and is easily scratched by tooling and shipping equipment, and the guardrails are seriously stained. Therefore, the effective coating protection of the guardrail is particularly important. [0003] At present, most of the guardrails mainly use solvent-based industrial coatings, which release volatile organic compounds (Volatile Organic Compounds, VOC) during production and use, resulting in pollution. At present, they have become the main source of pollution in cities after cars, endangering the human body healt...
