The self cross link acrylic acid elastic emulsion is used for decoration coating layers of internal walls and external walls of buildings. The self cross link acrylic acid elastic emulsion is prepared from 6 to 16 portions of acrylonitrile, 0 to 20 portions of vinyl tert-carbonate, 20 to 45 portions of various kinds of unsaturated carboxylate ester, 0.1 to 10 portions of polymerization organosilicon monomers, 0.5 to 3 portions of surfactant, 0.1 to 0.5 portion of free radical initiators and 42 to 54 portions of deionized water by weight. The aggregate is composed of self cross link acrylic acid emulsion, cement, calcium powder, talcum powder, auxiliary agents, etc. The lacquer putty is prepared from self cross link acrylic acid elastic emulsion and matched aggregate which is prepared from self cross link acrylic acid emulsion, cement, calcium powder, talcum powder, auxiliary agents, etc., has the advantages of high adhesive force, water resistance, alkali resistance, no formaldehyde, no poison, odourlessness, etc., and belongs to environmental protection products.
Description
The present invention relates to a kind of emulsion that is used to build inner, external wall finishing coating and by the putty of its preparation.
Current domestic, the putty that interior wall uses is that 107 glue (polyvinyl formal) or the improvement product (reducing the content of free formaldehyde) released in the recent period are equipped with aggregate and form, this series products is not water-fast, more not alkaline-resisting, so this class back cover putty layer, because what body of wall oozed out contains buck vapour, and destroyed, peel off.Aspect in addition, the exterior wall application, usually adopt primary coat (with the emulsion of diluting) and in be coated with, in be coated with material therefor and then be equipped with aggregate (being mainly filler and less pigment) with benzene emulsion or pure-acrylic emulsion, coating layer lacks flexibility in this class, and alkali resistance is poor, often because its coating be full of cracks, be difficult to prevent that body of wall from containing the infiltration of buck vapour, the destruction that is coated with in causing equally and influence the life-span of decorating finish paint.
The objective of the invention is at the putty of existing use or in the shortcoming of coating, developed a kind of formaldehyde, nontoxic, odorless and coating of not containing and done solid back rubber-like from the interlinkage ACRYLIC EMULSION, be equipped with aggregate, make putty, be used to build inner, external wall finishing blade coating.
The realization of the object of the invention is to introduce tertiary ethylene carbonate and polymerizable organosilane monomer in emulsion formulations, and the former has good hydrophobicity, good UV resistant and alkali resistance, thereby improves the weathering resistance of emulsion, and it gives the flexibility of coating; Introduce the polymerizable organosilane monomer, then can improve adhesive force of coatings, scrub resistance and outdoor weatherability greatly.
Preparation from the interlinkage acrylic elastic emulsion is by 6-16 part (wt, down together) vinyl cyanide; 0-20 part tertiary ethylene carbonate; The multiple esters of unsaturated carboxylic acids of 20-45 part, its molecular formula is:
