Abstract
The invention provides a water-based antiseptic paint for an automotive chassis. The automotive paint is prepared by mixing the following components in parts by weight: 48-52 parts of LH-302 resin, 2.0-2.5 parts of carbon black, 7-9 parts of iron black, 12-13 parts of modified aluminum tripolyphosphate, 1-3 parts of organic nitrogenzinc salt, 9-11 parts of modified filler, 0.3-0.5 parts of wetting dispersant, 0.8-1.0 part of corrosion inhibitor, 0.3-0.5 parts of substrate wetting agent, 0.1-2.0 parts of assistant and 10-12 parts of deionized water. The water-based antiseptic paint for the automotive chassis provided by the invention can be naturally dried at normal temperature and can be dried at a low temperature (dried for 0.5 hour at 80-90 DEG C), the paint film property is remarkably enhanced, and the adhesive force, the hardness and the salt fog resistance are ideal. The paint is mainly used for automobile axles, automotive chassis, auto parts and the like.
Description
Technical field: [0001] The invention relates to the field of paint, in particular to a water-based automobile chassis anticorrosive paint and a preparation method thereof. Background technique: [0002] With the increasing awareness of people's environmental protection and the corresponding promulgation of environmental protection laws and regulations in various countries, solvent coatings have become more and more restricted due to their high content of volatile organic compounds (VOC) and serious pollution of the ecological environment. Water-based black car chassis anticorrosive paint is a new technology in the field of environmental protection. It adopts IPN interpenetrating network technology, which not only achieves zero VOC emissions, improves the environment, reduces labor intensity, and the film performance can be comparable to solvent-based coatings. , The construction equipment and construction conditions are also similar to the construction of solvent-based coatings,...
