Abstract

The invention discloses a novel aqueous damping coating material for automotive interiors, a preparation method and equipment thereof, wherein the novel aqueous damping coating material is prepared from the following components in parts by weight: 10-20 parts of a graphene slurry, 1-3 parts of a defoaming agent, 0.5-1.5 parts of a thickening agent, 50-60 parts of modified glass powder, 3-5 parts of a curing agent, 30-40 parts of an environment-friendly flame retardant, 60-80 parts of a filler and 2-6 parts of a film forming aid. 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 ofthe material are solved, the comprehensive performance of the material is improved, the preparation process is simplified, the number of the equipment is reduced, and the comprehensive manufacturing cost is reduced; after the graphene and the modified glass powder in the material are mixed, a stable damping structure is formed in the coating; and the bubbles generated in the mixing process of thegraphene and the modified glass powder are removed through the defoaming agent, so that the damping layer is mixed tightly, the gaps are filled, the strength of the damping layer is improved, the preparation process is simplified, and the number of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of damping coatings, in particular to a novel water-based damping coating for automotive interior decoration, a preparation method and equipment. Background technique [0002] The damping coating is prepared by adding a proper amount of fillers and auxiliary materials to a polymer resin. It is a special coating that can be coated on the surface of various metal plate structures. It has vibration reduction, heat insulation and certain sealing properties. It can be widely used. It is used for the vibration reduction of aircraft, ships, vehicles and various machinery. Since the coating can be directly sprayed on the surface of the structure, the construction is convenient, especially for the surface with complex structure such as ships and aircraft, etc., it shows its superiority. Damping coating Generally, it is directly applied on the surface of the metal plate, and it can also be used in conjunction with epo...
