Description

A kind of interior wall that is used for is eliminated the coating that brush mark increases sophistication

Technical field

The present invention relates to the coating of rubber-emulsion paint, after adding polyvinyl alcohol solution, produce the brushing effects that is coated with of difference, the touch and the sensory effects that especially produce are the aftertreatment of engineering and remedy its defective, have found preferred plan.

Background technology

Rubber-emulsion paint is the principal item of trade sales coating, in construction process, occurs through regular meeting that whiteness is not good, brush mark is apparent in view or feel is not good enough, even causes paint film defect etc., under the prerequisite of getting rid of human factor, also should consider the chemistry, physical behavior of product etc.

Very various of the emulsion paint coating content that literature search discloses, particularly after the reform and opening-up, the rise of building industry and the paces of Product Renewal are irresistible, and the method that adopts polyvinyl alcohol water solution that the coating of rubber-emulsion paint is implemented modification is actually rare; The present invention's design is through production practice and Product Validation, and its technique effect is splendid, and it also is undoubted producing the booming market prospect for sales.

Summary of the invention

The objective of the invention is to: the present invention adds the polyvinyl alcohol water solution (concentration is 4%) of 2-5% in latex coating, method produced excellent sense organ effect, both be applicable to common interior wall coating, also use exterior coating.

The present invention seeks to realize like this: a kind of interior wall that is used for is eliminated the coating that brush mark increases the feel sophistication; Raw material is prepared with parts by weight, is made up of for 0.30 part deionized water 30-33 part, Mierocrystalline cellulose ER-30M 0.10-0.18 part, 250 sanitas 0.10-2.0 parts, AMP-95 amine neutralizing agent 0.5-1.0 part, NP-10 wetting agent 0.10-0.15 part, Ucar 35 0.5-0.8 part, 5040 dispersion agent 0.4-0.8 parts, 123 skimmer 0.10-0.15 parts, white titanium pigment 6.0-15.0 part, 800 order coarse whiting 25.0-35.0 parts, fine particle calcium carbonate 5.0-8.0 part, 1250 order kaolin 5.0-12.0 parts, OE300 film coalescence aid 0.2-0.5 part, ECO 502 emulsion 10.0-12.0 parts, 2% whitening agent 0.10-0.20 part, 0.2 part of 1130H thickening material, 0.40 part of 635 thickening material, 0.40 part of 632 thickening material, 621N thickening material; Wherein 1130H thickening material, 635 thickening materials, 632 thickening materials use after the dilution with the 1:1 amount respectively; The 621N thickening material evenly uses the back with the mixed with propylene glycol of 1:1 amount; Through preparing: raw material is dropped into reaction kettle successively; Under normal temperature, normal pressure, stirred 30-40 minute, adding concentration again is 4% Z 150PH 2-5 part, continues to stir 15-20 minute; Use can be sprayed, brush evenly, the effect of eliminating brush mark and increasing the feel sophistication can be produced.

Described coating selects for use the Mierocrystalline cellulose ER-30M in the raw material to originate from Tao Shi; AMP-95 amine neutralizing agent, 621N thickening material originate from Japanese Luo Puke; Film coalescence aid OE300 originate from U.S.'s hamming this; Emulsion ECO 502 originates from BASF; 123 skimmers, thickening material 1130H, 632,635 originate from Shenzhen Hai Chuan respectively; White titanium pigment (sharp) originates from and is Shanghai face titanium; The NP-10 wetting agent originates from Beijing Xing Meiya.

Design of the present invention and know-why: gather ethanol character: Z 150PH is that vinyl acetate between to for plastic generates Vinyl Acetate Copolymer through polyreaction, and Vinyl Acetate Copolymer is under different alkali number effects then, and saponification gets the different Z 150PH of alcoholysis degree.The cold cut pva powder is to be milled and process through deep cooling by partial alcoholysis type Z 150PH, is a kind of water-soluble environment protective type white powder.That external form is divided is cotton-shaped, three kinds of particulate state, powdery; Nonpoisonous and tasteless, pollution-free, can in 80--90 ℃ of water, dissolve, have good film forming properties and cohesive force, epithelium snappiness, smoothness, solvent resistance, rub resistance and tensile strength, have chemical property such as long-chain polyhydric alcohol esterification, etherificate, acetalation.

The present invention makes it become a homogeneous phase through the selected of 20 kinds of raw materials and preparation, adds 4% the aqueous ethanolic solution that gathers; Solved caking; Defectives such as feel is poor, brush mark is heavy, whiteness is not good, though handle to doing over again to remedy effect like this too, technical application; Cheap, show technical progress.
