Background technology
Damping paint, compared with traditional damping material such as rubber and foam plastics etc., has easy construction safety, environmental protection, adhesive strength advantages of higher；And damping material proportion is less, the requirement of material lightweight can be met.Automobile damping material, when for positions such as outside vehicle such as base plate, mud guard, wheel covers, can effectively absorb rubble suffered in vehicle traveling process and the energy of sand dashed sand generation, prevent damage and the corrosion of automobile；When for vehicle interior, it is possible to decrease vibrations that vehicle motor produces also reduce noise, are to apply at present a quite varied class material.And along with the change of environment, during damping paint is applied, its water-acid resistance is required more and more higher.
The at present research the most seldom to the damping paint with excellent water-acid resistance, the coating that more has been the demand behaviors for all trades and professions differs from one another.A kind of waterproof acid and alkali-resistance coating (201310719401.8) of Chinese patent discloses a kind of waterproof acid and alkali-resistance coating prepared with acrylic emulsion, polyurethane, rosin modified phenolic resin, filler, hydroquinone, methyl iso-butyl ketone (MIBK), butyl acetate etc. as raw material, it is possible at saturated Ca (OH)2Aqueous solution soaks and within 20 days, does not changes.But the hydroquinone in this formulation for coating material, methyl iso-butyl ketone (MIBK) all have toxicity so that environment and human body are damaged during using by coating.The development (201410779039.8) of the Chinese patent extra-weather-proof simulated tile coating of a kind of antiacid alkali resistant discloses the thick matter sandstone coating that a kind of storage stability is good, workability is excellent, there is the water-fast weatherability of excellence, but pure-acrylic emulsion in raw material, import auxiliary agent etc. is relatively costly, the benefit metaplasia being unsuitable for enterprise is produced.A kind of heat-resisting water-acid resistance coating (201510531359.6) of Chinese patent discloses a kind of water-tolerant, and thermostability, acid-alkali-corrosive-resisting are excellent and have the coating of certain anti-flammability.But this invention formula is complicated, raw material is many, cost is big, is unfavorable for industrialized production.
Summary of the invention
Present invention aim at providing a kind of water-acid resistance damping paint, its water resistance with excellence and acid-proof alkaline, can effectively improve the service life of damping paint, cost of material is low simultaneously, environment-protecting asepsis, preparation technology are simple.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
The preparation method of the present invention a kind of water-acid resistance damping paint, it is characterized in that having following preparation process and step: the compositing formula of a. coating and dispensing, its raw material includes following components by weight: waterborne styrene-acrylic emulsion 40-50 part, filler 15-25 part, fire retardant 10-15 part, dispersant 0.2-0.5 part, defoamer 0.2-0.5 part, multifunctional assistant 2.5-3 part, coalescents 1-2 part, thickening agent 1-1.5 part, chopped fiber 0.5-1.5 part, Pulvis Talci 12-20 part；
Described filler is the one in white mica powder, sericite in powder, and granularity is between 40 mesh to 200 mesh；
Described fire retardant is the one in aluminium hydroxide, magnesium hydroxide or Firebrake ZB；
Described dispersant is universal 731A dispersant, formaldehydeless；
Described defoamer is universal aqueous defoamer；
Described chopped fiber is long 5mm, the glass fibre of a diameter of 1mm；
Described multifunctional assistant is AMP-95 multifunctional assistant；
Described coalescents is alcohol ester-12；
Described thickening agent is any one in VA-2 system acrylic thickener, VA-3 system acrylic thickener or polyurethane thickener, is both needed under alkaline environment under allotment use.
B. the preparation process of coating: a certain amount of waterborne styrene-acrylic emulsion being added in container and stir under dispersion machine, dispersion mixing speed is 500r/min；And add above-mentioned a certain proportion of chopped fiber, dispersant, defoamer, and stirring 20 ~ 30min, dispersion mixing speed is 1000r/min；Adding in aqueous mixed emulsion after above-mentioned a certain proportion of filler, fire retardant, Pulvis Talci mixing again, after stirring 30 ~ 50min with mixing speed for 1500r/min with dispersion machine, addition coalescents, multifunctional assistant are stirred for 30 ~ 50min；Finally, add thickening agent regulation denseness, stir 20-30min with the dispersion mixing speed of 1000r/min, finally give water-acid resistance damping paint.
The present invention uses waterborne styrene-acrylic emulsion as main film forming substance, strengthen the mechanical performance of damping paint by the mixing that adds of filler, auxiliary agent, and the addition of dispersant, defoamer makes coating can preferably mix during preparation and obtain closely knit product.The addition of thickening agent simultaneously can play good thickening effect, can be obviously enhanced the adhesion strength of coating, water-acid resistance, and Pulvis Talci makes coating be more easy to construction, substantially reduce surface drying and the time of doing solid work with the addition of coalescents.
The present invention has following significantly advantage: raw material of the present invention is simple and easy to get, and preparation is simple, and preparation cost is low.First, this damping paint has the water-acid resistance performance of excellence, can be effectively improved the service life of coating；Secondly as the emulsion used is water-based emulsion, raw material environmental protection, pollution-free, therefore obtained product is without poisonous and harmful substance, environmental protection；3rd, this damping paint caking property is good, surface drying with do solid work that speed is fast, preparation technology simple, be suitable for industrialized production.
