It is also higher and higher to its water-acid resistance requirement during.
Research to the damping paint with excellent water-acid resistance at present is simultaneously few, and more is for all trades and professions
Demand behaviors coating with their own characteristics.A kind of waterproof acid and alkali-resistance coating of Chinese patent（201310719401.8）Disclose one
Kind is with acrylic emulsion, polyurethane, rosin modified phenolic resin, filler, hydroquinone, methyl iso-butyl ketone (MIBK), butyl acetate etc.
It, can be at saturation Ca (OH) for the waterproof acid and alkali-resistance coating that raw material is prepared2It impregnates 20 days and does not change in aqueous solution.
But the hydroquinone, methyl iso-butyl ketone (MIBK) in the formulation for coating material all have toxicity so that coating is during use to ring
Border and human body damage.A kind of development of the antiacid extra-weather-proof simulated tile coating of alkali resistant of Chinese patent（201410779039.8）It is open
A kind of storage stability is good, workability is excellent thick matter sandstone coating has excellent water-fast weatherability, however in raw material
Pure-acrylic emulsion, import auxiliary agent etc. cost it is higher, be unsuitable for the benefit metaplasia production of enterprise.Chinese patent is a kind of heat-resisting water-fast
Acid and alkali-resistance coating（201510531359.6）A kind of water-tolerant is disclosed, heat resistance, acid-alkali-corrosive-resisting are excellent and with one
Determine the coating of anti-flammability.But invention formula is complicated, raw material is more, cost is big, is unfavorable for industrialized production.
The content of the invention
Present invention aims at a kind of water-acid resistance damping paint is provided, with excellent water resistance and acid and alkali-resistance
Performance can effectively improve the service life of damping paint, while cost of material is low, environment-protecting and non-poisonous, preparation process is simple.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of preparation method of water-acid resistance damping paint of the present invention, it is characterised in that have following preparation process and
