Aqueous anticorrosive damping coating material for automobile chassis, preparation method and equipment thereof

Abstract

The invention discloses an aqueous anticorrosive damping coating material for an automobile chassis, a preparation method and equipment thereof, wherein the coating material is prepared from the following components in parts by weight: 55-75 parts of an aqueous polymer elastic resin emulsion, 30-40 parts of a damping pigment filler, 20-40 parts of aluminum fiber, 10-20 parts of a preservative, 8-16 parts of a flame retardant, 6-10 parts of a film forming aid, 20-30 parts of deionized water, 1-3 parts of a thickening agent, 0.7-0.9 part of a defoaming agent, 2-4 parts of a compatilizer and 0.6-0.8 part of a coupling agent. The invention relates to the technical field of aqueous damping coating materials. According to the invention, by improving the matching of the components, the preparation method and the equipment of the material, the problems of low comprehensive performance, complex preparation process, many devices and high comprehensive manufacturing cost of the material are solved, the comprehensive performance of the material is improved, the preparation process is simplified, the number of the equipment is reduced, and all steps can be completed in one equipment so as to reduce the comprehensive manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of water-based damping coatings, in particular to a water-based anti-corrosion damping coating for automobile chassis, a preparation method and equipment. Background technique [0002] Water-based damping coating is an environmentally friendly coating that can reduce vibration and noise. At present, there are many types of damping coatings at home and abroad, but from the solvent of the coating, there are mainly two types: solvent-based and water-based. The former mostly contains organic solvents and asphalt. , high toxicity, high volatility, polluting the environment and poor workability, it is now less used. The latter damping coating uses water as a solvent, which has low toxicity, low odor, low cost, easy construction and environmental protection. It is a good choice for railways, automobiles, aviation It is the first choice product for damping coatings used in construction and construction industries. S...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the above-mentioned deficiencies of the prior art, the present invention provides a water-based anti-corrosion damping paint for automobile chassis, a preparation method and equipment, and focuses on improving the compatibility of the components used in the material with the preparation method and equipment to solve the problem of existing water-based damping coatings. The coating has insufficient damping performance, does not have anti-corrosion and flame-retardant effects, has low safety in use, cannot meet the needs of use, and has problems such as low comprehensive performance of materials, complicated preparation process, many equipments, and high comprehensive manufacturing costs.
