Description
Technical field
The present invention relates to a kind of coating of chemical field, particularly be applied to the protective cover on industrial wood furniture surface.
Background technology
The woodwork coating of China's use at present is mostly solvent-borne type, and these woodwork coatings all contain a large amount of volatile organic compounds (VOC), and serious harm producers and workmen's is healthy.Along with the enhancing of people's environmental consciousness, conventional solvent type coating faces a severe challenge, the advantage such as that water-borne coatings has is nontoxic, nonflammable, nonpollution environment.Water-borne coatings combines the high performance of solvent based coating with the low VOC content of water-borne coatings, environmental effect is good, construction is relatively convenient.But China's water-borne coatings now is in the technology starting stage, and film performance does not often reach human consumer's requirement, has defects such as easily subsiding, fill not, fullness ratio is inadequate, hardness is not strong.
Summary of the invention
For above-mentioned technological deficiency, the technical problem to be solved in the present invention is to improve the aqueous, environmental protective pyroxylin(e)finish.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of aqueous, environmental protective pyroxylin(e)finish, percentage composition is by weight: water-base resin 8～10%, softening agent 2～3%, dispersion agent 0.5～1 %, ethyl ester 4～5%, butyl ester 6～8%, low second nitro-cotton 20～25%, butanols 6～10%, emulsion 2～3%, construction base-material 1～2%, surplus are water.
Further: in above-mentioned aqueous, environmental protective pyroxylin(e)finish, described water-base resin is one or both in Hydroxylated acrylic resin, oleic acid modified alkyd resin.Described softening agent is DEDB, and its molecular formula is that the C18H18O5 molecular weight is 314, and its effect is the snappiness that increases paint film.Described dispersion agent is aqueous dispersant.Namely the BYK192 that German Bi Ke chemical company provides.Described emulsion is ACRYLIC EMULSION.Its effect is the consistency that increases between film forming sticking power and increase resin and water and alcoholic solvent.Use in this programme is WA-2005 and the WA-2006 of U.S. Hua Jinsi company.Described construction base-material is that 1-Methoxy-2-propyl acetate (PMA) is a kind of senior solvent, and existing ehter bond in its molecule, have again carbonyl, and carbonyl has formed again the structure of ester, contains again alkyl simultaneously.Existing nonpolar part, have again polar portion in same a part, and this two-part functional group is restriction repulsion mutually both, plays separately again its intrinsic effect.Therefore, apolar substance and polar material there is certain dissolving power.The solvent that is a kind of relative slow curing is used for adjusting dried speed.One or both in propylene glycol.The effect of propylene glycol is that frostproofer protective paint construction amplitude in the winter time is good.When making aqueous, environmental protective pyroxylin(e)finish of the present invention, drop in order resin, cotton pulp, softening agent, solvent, add mute powder and remaining material under stirring, with the clean cylinder of solvent cleaning limit powder, then 1500 turned high speed dispersion 30 minutes.
The present invention also provides the constructional method of above-mentioned aqueous, environmental protective pyroxylin(e)finish, it also comprises that the weight percent of described thinner consists of ethanol 5～10%, isopropylcarbinol 5～15%, vinyl acetic monomer 15～20%, N-BUTYL ACETATE 37.5～50%, 1-Methoxy-2-propyl acetate 10～15%, dibasic ester DBE 1～2%, deodovization agent 0.05～0.1% with the step of aqueous, environmental protective pyroxylin(e)finish with the thinner dilution.Dibasic ester is the material that those skilled in the art commonly use.The weight ratio of described aqueous, environmental protective pyroxylin(e)finish and thinner is 100:(18-22).Thinner is mainly the effect of playing dilution in construction process, reduce the working viscosity of coating, each component selection principle in formula is under the prerequisite of the performance such as the surface drying speed, sag resistance, levelling when guaranteeing paint application, select the kind that solvency power is strong, boiling point is low, volatilization is fast, murder by poisoning is little, need assess the smell of solvent itself simultaneously, reach quick-drying, low smell, residual few purpose.The preparation method of thinner, feed intake in order, and stirring at low speed mixes rear censorship, beats chromatogram check composition.
Compared with prior art, the useful technique effect of above-mentioned aqueous, environmental protective pyroxylin(e)finish is:
1. because aqueous, environmental protective pin base paint is to adopt advanced polyurethane system, ultralow VOC content (lower than the compulsory standard of national 200mg/L), be real nonpoisonous and tasteless high-tech environmentfriendly products.
2. aqueous, environmental protective pin base paint has adopted water to replace organic solvent, its product to have the non-flammable characteristics of safety.Hazard Factor and the trouble of production, intermediate links have been reduced widely.
3. aqueous, environmental protective pin base paint has adopted water to replace organic solvent, and its product in brushing, can not produce any pungent odour.
4. to have a brushing pass few for aqueous, environmental protective pin base paint, and quick-drying, easily be coated with, and do not join the time limitation after paint, is painted with namely and can moves in.
