example 1

[0024] In terms of parts by weight, 30 parts of mica, 20 parts of bentonite, 20 parts of calcium silicate, 5 parts of titanium dioxide and 8 parts of talcum powder were respectively selected, mixed and added to a ball milling tank for ball milling for 2 hours. After ball milling, 300-mesh sieve was collected. To obtain the mixed powder, add the mixed powder into water according to the mass ratio of 1:5, stir and mix for 10 minutes, then add 5% cetyltrimethylammonium bromide of the mixed powder mass, ultrasonically disperse for 10 minutes under the condition of 10KHz, and obtain a suspension after dispersion Liquid, add suspension quality 3% castor oil and suspension quality 5% dimethylmethanol to the suspension, after stirring for 5min, let it stand for 2h, put it into the centrifuge after standing, and centrifuge at 2000r / min speed, Collect the precipitate and put it in an oven, dry it at 60°C for 4 hours, collect the dry powder, which is the damping filler, and select 5 parts...

Abstract

The invention discloses water-based flame-retardant damping paint, and belongs to the technical field of paint. A preparation method of the water-based flame-retardant damping paint comprises the steps of preparing mixed powder by taking mica, bentonite and the like as raw materials, performing mixed dispersion with water and cetyl trimethyl ammonium bromide to obtain a suspension, performing centrifugal separation with castor oil and dimethyl carbinol, collecting a precipitate, performing drying to obtain a damping filler, adding the damping filler to epoxy resin, grafting an acrylic acid monomer, performing rotary evaporation to obtain a damping filler modified resin emulsion, preparing modified guar gum by taking guar gum as a raw material, mixing the water, ethylene glycol monophenyl ether, a defoaming agent and the like, adding ground calcium carbonate, expanded graphite and the like, performing grinding to obtain slurry, mixing the slurry with the damping filler modified resin emulsion, the modified guar gum and the like, and performing discharge to obtain the water-based flame-retardant damping paint. The prepared damping paint has the advantages of good low-temperature damping performance, wide damping temperature range and good flame retardance, is moderate in drying time and better in workability, and has a wide application prospect.

Description

technical field [0001] The invention discloses a water-based flame-retardant damping coating, which belongs to the technical field of coatings. Background technique [0002] Vibration and noise are common problems in various industries and need to be solved urgently, mainly including traffic noise, industrial noise and living noise. At present, developed countries have already legislated against noise hazards, and vibration and noise reduction technologies and materials are widely used in electromechanical products. Among them, damping material, as a material that can effectively reduce the vibration and radiation noise of equipment and wall structures, is widely used in many fields such as aircraft, rail trains, automobiles and ships. [0003] Damping coating is a special coating with vibration reduction, sound insulation and certain sealing performance, and it is an environmentally friendly vibration and noise reduction material. Damping paint is prepared by adding appro...
