Abstract
The present invention relates to antistatic emulsion coating for internal walls, which is indoor architectural coating and is prepared by adding a liquid two-element antistatic agent in the processing of the emulsion coating containing high polymer emulsion, stuffing, coloring material and auxiliary agents. The coating is used as internal wall coating in the industries of electronics, chemical engineering, production of textiles and precision instruments, etc., and the coating can avoid fire hazards, explosion and other accidents caused by static electricity.
Description
The present invention relates to a kind of interior architecture finishing material, belong to the invention of building coating aspect.
Along with industrial expansion, the static hazard in industries such as chemical industry, electronics, weaving and precision instrument manufacturing becomes increasingly conspicuous, in producing assembling or storage process, because electrostatic accumulation and discharge fire hazardous and explosion hazard.At present, it is few to be used for the Antistatic Paint kind of building trade.The described Antistatic Paint technology of Japanese Patent JP63000368 is the coating that is used for floor, top ceiling, wall, and its film forming matter is the polyformate resin, and conductive additive is a Zinc oxide powder.Macromolecular material all is electrically insulating material basically, adopt some means can make them become the macromolecular material of conduction, two kinds of conducting polymer composite separation structure type and mixed types, the former does not develop into the practical stage as yet, and the conductive additive that the latter uses in the prior art (as the JP63000368 patented technology) adopt pressed powder, comprise metal powder, metal oxide powder, carbon black powder etc., adopt the metal-powder of non-valuable class to have the problem of burning.Carbon black powder is only applicable to dark coating, and list is more difficult to get low-resistance coating with the metal oxide powder.
The purpose of this invention is to provide a kind of interior wall coating that conductive additive can conduct and leak static electric charge that adds.
The present invention seeks to realize like this, it comprises polymer emulsion, filler, colorant and film coalescence aid, dispersion agent, defoamer and thickening material, in the coating component, add the double base static inhibitor, their total content accounts for 1-20% of coating gross weight, and every kind of static inhibitor can account for 1-15% of coating weight in selected two kinds of static inhibitor.
Filmogen that the present invention contains is a kind of polymer emulsion, can adopt benzene emulsion (being the multipolymer of vinylbenzene-propionic acid alkene-acrylate or the multipolymer of vinylbenzene-vinylformic acid-methacrylic ester) or with vinyl acetate emulsion (multipolymer of vinyl acetate between to for plastic-acrylate).Auxiliary agent in the coating comprises film coalescence aid, dispersion agent, defoamer, thickening material etc.
The conductive additive (static inhibitor) that this coating adopts has following several:
1, maleic anhydride macrogol ester.
2, sim alkylphenol Soxylat A 25-7, its its name of product are static inhibitor 0 π-10.
3, polyvinyl 1# finish.
4, trihydroxyethyl methyl quaternary ammonium Methylsulfate, its name of product is an antistatic agent TM
In four kinds of above-mentioned coating any two kinds all capable of being combined.
The present invention adds two kinds in the above-mentioned static inhibitor on the basis of copolymer emulsion coating.The moisture content that the ion that static inhibitor ionization forms, film coated surface absorb and film inner polar molecule and polar group play conduction and leak charge jointly, thereby the static inhibitor that has prevented the combination of electrostatic accumulation adding double base can make two kinds of static inhibitor performance complements, increases anti-static ability.
The interior wall that this coating can be used for the requirement anti-electrostatic is cement, concrete and the surfaces such as timber of having considered problem with grounding.
This coating can be used for weaving, the inner wall surface of the industries such as production of chemical industry, oil, electronics, precision instrument.Adopt this coating to help avoid accidents such as fire that indoor static causes and blast.
