The background technology resin latex dope is present main interior wall coating, is take synthetic resin emulsion as binding material, adds pigment, filler and various auxiliary agent, the slim interior wall coating that forms through grinding.Because synthetic resin emulsion used is different, performance, the class of the coating of concrete kind are also just variant.Synthetic resin emulsion commonly used has: acrylic ester emulsion, vinylbenzene one acrylate copolymer emulsion, vinyl acetate between to for plastic one third ethene acid esters emulsion ", vinylchlorid one vinylidene chloride emulsion etc.The kind of resin latex dope commonly used and applicable building class: interim or common building: ethene-vinyl acetate emulsion copolymer paint.Middle-grade building: vinyl acetate between to for plastic-acrylic latex coating, styrene-acrylic latex paint, vinyl acetate between to for plastic-tertiary ethylene carbonate emulsion copolymer paint.Top-grade building: pure acrylic acid emulsion paint, silicon the third emulsion paint, aqueous polyurethane coating, aqueous fluorocarbon coating.Can be divided into inferior light, half inferior light, high light and mercerising etc. by the coating film gloss degree.Can be divided into elasticity and non-resilient by being coated with film type.Compare with the emulsion paint of general significance, elastic coating can cover the fine cracks of metope.
Summary of the invention the present invention can prepare the environmental protection coating material of objectionable impuritiess such as not containing free formaldehyde, benzene, toluene, ethylbenzene, dimethylbenzene by mixing a certain proportion of synthetic resin emulsion, has flexible coating, smooth exquisiteness, seepage force, strong adhesion, and inexpensive, be convenient to the advantage for preparing and construct.This synthetic resin emulsion consists of: multiple vinylbenzene, acrylate monomer be through emulsion, vinylformic acid, methacrylic acid, methyl methacrylate, and the multiple units such as methyl esters, esters of acrylic acid and functional aid are poly-, the emulsion that forms by the Optimization Technology copolymerization.
Technical scheme provided by the invention is: a kind of synthetic resins toxicological harmless Environmental Protective Water-paint, it consists of: 40-70 part synthetic resin emulsion, 0.1-2 part carboxymethyl cellulose, 40-55 part pure water, 40-60 part calcium carbonate, 3-12 part titanium dioxide, 1-6 part kaolin, 8-28 part talcum powder, 8-18 part wollastonite powder, 10-30 part zinc sulfide white, 2-22 part kidney mica, 1-10 part bentonite thickener, 1-10 part lauryl alcohol ester, 3-10 part propylene glycol, 2-10 part additive and auxiliary agent etc.(by weight)
The technological specification of the specific embodiment of the invention and each flow process is as follows: water and raw material prepare and stir with auxiliary agent in proportion, again temperature is raised to about 60-110 degree, add synthetic resin emulsion and film forming to stir, temperature keeps the 60-100 degree, then adds thickening material to filter to form.
The outstanding feature of the coating of the present invention's preparation is:
1, the major part of the main raw material of this coating source is abundant, and cheap
2, this coating preparation technique is simpler, and processing parameter is more easy to control
3, this coating environmental protection, toxicological harmless, do not produce or the harmful free formaldehyde that volatilizees, stupid be the toxic substances such as thing
4, this coating can be in indoor curing, easy construction, be convenient to the construction of the methods such as indoor brushing, roller coating, spray.
