Abstract

The invention discloses a UV light curing hardware coating which comprises raw materials in parts by weight as follows: 45-50 parts of polyester acrylate, 20-25 parts of metacrylic acid ester, 10-14 parts of ethyl acetate, 3-4 parts of thiol polyorganosiloxane, 10-12 parts of dipentaerythritol hexaacrylate, 1-2 parts of a silane coupling agent KH560, 12-14 parts of tricresyl phosphate, 1-2 parts of methyl methacrylate, 3-5 parts of ethylene glycol monoethyl ether acetate, 1-2 parts of isoamyl butyrate, 4-6 parts of a photoinitiator 2959, 1-2 parts of manganese acetate and 4-5 parts of a dispersing auxiliary. According to the UV curing hardware coating, polyester acrylate and metacrylic acid ester are adopted as main materials, and plasticization and reinforcement substances such as tricresyl phosphate, manganese acetate and the like are added, so that the obtained coating has good cohesiveness, strong abrasive resistance, acid-base resistance, corrosion resistance and insulation; the UV coating is suitable for being used as the priming paint of hardware, zinc alloy, aluminum alloy and stainless steel and used as vacuum plating UV coating, the coating has durable performance, is superior to coatings for decorations of an automobile, a motorbike, a mobile phone and an electronic component in the market, and is strong in universality and high in curing speed; and the UV curing hardware coating has high production efficiency, saves cost and is simple in production process.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a UV photocuring hardware coating and a preparation method thereof. Background technique [0002] With the development of the market economy, great changes have taken place in the field of coatings. Among them, UV coatings have the advantages of fast curing speed, energy saving, room temperature curing, superior performance, and environmental protection. The surface is strong and heat-resistant, and the refraction effect is good, so that the substrate has a strong sense of subject. It has been widely used in chemical industry, machinery, electronic light industry, communication and other fields. Due to its environmental protection advantages, UV curing has received strong support from relevant environmental regulations and close attention from the industry. While the market demand for UV radiation curing materials is growing rapidly, UV radiation curing systems are being combi...
