Problems solved by technology

[0004] Epoxy resin coatings have good anti-corrosion and aging resistance effects, but there are the following problems: 1. Epoxy resin coatings are toxic and do not meet environmental protection requirements; 2. The surface treatment effect is not good and cannot be sprayed; 3. The curing time is long
It has the following problems: 1. Acetone is used as a solvent for epoxy resin coatings, which is toxic and does not meet environmental protection requirements; 2. The operation process is complicated, energy consumption is large, and the cost is high; 3. The application range is narrow, and molds are required for laying glass filaments. High-temperature heating furnace is required, and cannot be operated outdoors or on site.

Abstract

The invention discloses a nano light-cured anticorrosion spray-coating liquid relating to the field of treatment on surfaces of metal, concrete and wooden products. The nano light-cured anticorrosion spray-coating liquid consists of the following components in weight ratio: 50-60% of epoxy acrylate resin; 15-20% of trimethylolpropane acid resin; 3-5% of tripropylene glycol triacrylate triacrylic ester; 2-5% of N-methyl pyrrolidone; 2-4% of benzil dimethyl ketal; 0.5-2% of titanium nitride nano powder and 16-20% of titanium dioxide powder. The spray-coating liquid can be cured by sunshine or an ultraviolet lamp and is available for outdoor operation, wide in application range, non-toxic and odor-free, environment-friendly, simple in operation procedures, energy-saving and low in cost; and the formed layer has excellent resistance to corrosion, chemical and fading as well as remarkable adhesive property and has fireproofing property, good mechanical strength, dropping resistance, cracking resistance and pulverization.

Description

technical field [0001] The invention relates to the field of surface anticorrosion treatment of metal, cement and wood products, in particular to a nanometer light-cured anticorrosion spraying liquid. Background technique [0002] Due to the influence of the natural environment and the defects of material properties, most materials, especially metals, will be corroded, which will greatly affect their appearance and use effect, and even cause a lot of waste of resources and energy. Therefore, it is necessary to carry out anti-corrosion treatment on the surface of the material. [0003] The traditional method is to spray paint on the surface of the material, which has defects such as non-environmental protection, toxicity, poor anti-corrosion effect and aging resistance. Anti-corrosion coatings are widely used because they are easy to construct, not restricted by the area and shape of equipment, economical and applicable, and have certain decorative effects.
