High-solid dark-yellow fastness decoration finish paint special for engineering machinery and preparation method thereof

Abstract

A high-solid dark-yellow fastness decoration finish paint special for engineering machinery is prepared from the raw materials by weight: 30-32% of dark chrome yellow, 0.8-1% of nanometer barium sulfate, 57-61.6% of 70% acrylic resin, 0.1-0.2% of ultraviolet absorber, 0.5-0.8% of hindered amine antioxidant, 1-1.5% of barium cadmium zinc compound stabilizer, 1-1.5% of triphenyl phosphite, 4-5% of diluent, 0.5% of dispersing agent and 0.5% of film formation auxiliary agent. The raw materials are stirred, dispersed and the like, and then filtered and packaged when viscosity achieves a standard. The high-solid dark-yellow fastness decoration finish paint has the following advantages that the technique of drying thermoplastic acrylic resin by volatilization to form a film is adopted, the ultraviolet absorber and the hindered amine antioxidant are used, the barium cadmium zinc compound stabilizer and the triphenyl phosphite antioxidant are matched for the first time in the paint industry, and simultaneously, a certain amount of nanometer barium sulfate is added, so that the problems that bright colors such as dark yellow are apt to change, aging performance exists and the like when the decoration finish paint is used outdoors are solved, and simultaneously the cost is substantially lowered.

Description

technical field [0001] The invention relates to a high-solid-content deep yellow anti-discoloration engineering machinery special decorative finish paint and a preparation method thereof, belonging to the field of polymer material chemical industry. Background technique [0002] At present, construction machinery tower cranes all use dark yellow acrylic topcoat. The advantages of this coating are bright and bright. The disadvantages are: it is not resistant to aging, it will change color in half a month, it will lose its luster in three months, and it will start to pulverize in ten months, so it is very difficult to maintain large tower cranes. Different regions have different effects, especially in high-temperature and high-humidity regions, where the air quality is poor and contains SO2, CO2, etc. During the rainy season, the discoloration and light loss are faster, which is caused by acid rain; different seasons are also different, especially It's summer, with high tempe...
