[0033] 1. Example 1 Synthesis of LH-302 resin

[0034] Main raw materials

[0035] 1.1 Material composition

[0036] Epoxy resin E-42, fatty acid, high molecular weight regulator, silicone intermediate, methyl methacrylate (MMA), butyl acrylate (BA), methoxy polyvinyl alcohol methacrylate (MAA) acrylic hydroxy Ethyl acetate (HEA), surfactants, initiators, and mixed non-toxic solvents are all industrial products.

[0037] 1.2 The weight of each component used in resin preparation (kg)

[0038]

[0039] Wherein, the mixed solvent is a mixture of xylene, ethylene glycol ethyl ether acetate, and sec-butyl ester in a volume ratio of 3:1:1;

[0040] 1.3 Synthesis process

[0041] (1) Put the weighed fatty acid into the reactor, add epoxy resin, molecular weight regulator and part of the solvent, and carry out the esterification reaction at 150-160℃. When the acid value drops to 40mgKOH / g, it is regarded as esterification. At the end, the reaction system is cooled to room temperature;

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 nitrogen zinc 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,...
