The dried crack-resistant woodenware paint can form a continuous coating, and the coating has good elongation percentage, breaking strength, acid resistance, base resistance, excellent weatherability, excellent crack resistance and no environmental pollution.

Description

A kind of cracking resistance woodenware paint

Technical field

The present invention relates to decorative paint field, specifically belong to a kind of cracking resistance woodenware paint.

Background technology

Paint is that one firmly can cover body surface, plays protection, decoration, mark and the chemical mixture coating of other special purposes.Paint is thickness oil colour, inflammable in not dry situation, water insoluble, is slightly soluble in fat, dissolves in alcohol, aldehyde, ether, benzene, alkane, be soluble in gasoline, kerosene, diesel oil.

Kind is painted much in present market, but various paint is all made up of filmogen (various resin), solvent, pigment, siccative, additive.Common paint makes solvent with gasoline usually, and epoxy iron red shop primer is containing a small amount of dimethylbenzene, and dipping lacquer mainly containing toluene, also has a small amount of benzene, very large on human body impact.

Summary of the invention

The object of this invention is to provide a kind of cracking resistance woodenware paint, the prices of raw and semifnished materials are low, Harmful chemicals consumption is few, successional coating can be formed after paint drying, paint coating has good unit elongation and breaking tenacity, acidproof, alkali resistance good, have excellent weather resistance, the excellent property of cracking resistance, non-environmental-pollution.

The technical solution used in the present invention is as follows:

A cracking resistance woodenware paint, by weight, is made up of following raw material:

E-20 epoxy resin 30-40, short oil alkyd 3.5-5.5, dioctyl phthalate (DOP) 1.5-2.0, ethylene glycol 5-8, superfine talcum powder 10-12, ethylene glycol ethyl ether 0.3-1.2, Sodium hexametaphosphate 99 0.2-0.5, polymeric amide 0.3-3.0, silicon-dioxide fine sand 4-6, amide modifications hydrogenated castor oil 0.4-1.5, carbon black 5-7, silica flour 4-6, ACRYLIC EMULSION 12-15, water 46-50;

Its concrete preparation method is as follows:

By above-mentioned weight part, ACRYLIC EMULSION and Sodium hexametaphosphate 99, water are carried out suction header tank after pre-emulsification, another header tank of suction after E-20 epoxy resin, short oil alkyd, ethylene glycol water dissolution, two header tanks enter steel basin in the mode dripped simultaneously, and in steel basin, temperature controls at 70-80 degree, control rate of addition, reaction mass is dripped off at 2-3.5h, is then incubated 1-1.5h, then cool, cool rear and the abundant mix and blend of all the other raw materials, to obtain final product.

The present invention with E-20 epoxy resin for film coalescence aid, dimethylbenzene zero adds, the prices of raw and semifnished materials are low, Harmful chemicals consumption is few, successional coating can be formed after paint drying, paint coating has good unit elongation and breaking tenacity, acidproof, alkali resistance good, has excellent weather resistance, the excellent property of cracking resistance, non-environmental-pollution.
