[0040] (1) Preparation of damping layer

[0041] The damping layer is a water-based damping coating, and its main composition is shown in Table 1.

[0042] Table 1

[0043] component name weight (parts) lotion 30-50 wood fiber 2-5 Mica powder 20-40 Aluminum hydroxide 20-30 Waterborne Flame Retardant 10-20

[0044] Coalescent 10-20 Wetting and dispersing agent 0.5-1.5 thickener 0.5-2.0 water 10-20

[0045] The emulsion is at least one of water-based acrylic resin emulsion and polyurethane emulsion, with a solid content between 50% and 60%; water-based acrylic resin emulsion includes but not limited to pure acrylic emulsion, styrene-acrylic emulsion, vinegar-acrylic emulsion or silicon-acrylic emulsion , the preferred grade in the embodiment is the elastic styrene-acrylic emulsion (BASF) of Acronal7026 and the pure acrylic emulsion (Dow Chemical Company) of UCAR H-371; the preferred grade of polyure...

Embodiment 1

[0073] The damping material is a water-based damping paint, and the water-based damping paint in this embodiment includes: 30 parts of elastic styrene-acrylic emulsion (Acronal7026); 1.5 parts of wetting and dispersing agent sodium tripolyphosphate; 10 parts of coalescent propylene glycol butyl ether; 25 parts of 200-mesh mica powder; 5 parts of wood fiber; 20 parts of water-based flame retardant ammonium polyphosphate; 30 parts of 325-mesh aluminum hydroxide; 0.5 part of thickener diatomaceous earth; 20 parts of water.

[0074] When preparing, first add 1 / 2 of water and wetting and dispersing agent into the emulsion, stir well, then add wood fiber, water-based flame retardant, mica powder and aluminum hydroxide in turn, and finally add film-forming aids and thickeners and the remaining water, and stir evenly to obtain a water-based damping coating.

Abstract

The invention discloses a damping material comprising a damping layer, wherein the damping layer comprises the following components in parts by weight: 30-50 parts of emulsion, 2-5 parts of lignocellulose, 20-40 parts of mica powder, 20-30 parts of aluminum hydroxide, 10-20 parts of waterborne fire retardant, 10-20 parts of film forming additive, 0.5-1.5 parts of wetting dispersant, 0.5-2.0 parts of thickening agent and 10-20 parts of water. The invention also discloses a preparation method of the damping material; the prepared damping material contains no organic solvents, is safe, environment-friendly, free from environment pollution and excellent in damping performance and has the recombination loss factor of over 0.3.

Description

technical field [0001] The invention relates to the field of damping materials, in particular to a damping material and a preparation method thereof. Background technique [0002] Damping materials are mainly used to reduce structural vibration and noise of locomotives, automobiles, ships, aircraft, large equipment, etc. At present, most damping materials at home and abroad are solvent-based products, which emit a large amount of VOC (volatile organic compounds) during production and use, which seriously pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide a damping material and a preparation method thereof, so as to solve the problem of serious environmental pollution caused by existing damping materials. [0004] The technical solution is as follows: [0005] A damping material, comprising a damping layer, the damping layer comprises the following components according to the weight ratio: 30-50 parts of emulsion...
