Abstract
The invention discloses a preparation method of an organic-inorganic composite waterproof agent for exterior-wall gypsum building materials. Main raw materials of the organic-inorganic composite waterproof agent comprise methyl methacrylate, silica nanoparticles, polyvinyl alcohol, dibutyl phthalate, ammonium persulfate and an emulsifier. The organic material and inorganic polymer compounded waterproof emulsion obtained by the formula and the preparation method has integrated characteristics of organic materials' good caking property, strong corrosion resistance and compact and waterproof coating and inorganic materials' ageing resistance, pollution resistance, high hardness of coating and the like. The product is especially applied in preparing of exterior-wall gypsum, can remarkably enhance waterproofness of gypsum products and even more can show excellent physical and mechanical properties.
Description
Technical field
The present invention relates to building materials of gypsum technical field, especially a kind of preparation method of the Organic-inorganic composite water-resisting agent for exterior wall building materials of gypsum.
Background technology
Gypsum belongs to air-setting material, is applicable to doing materials for wall, have raw material sources extensively, material produce energy consumption is low, the advantages such as processing performance is good.But plastering water resistance is very low, cause its in wet condition intensity sharply decline and creep properties increase, be limited on exterior wall and apply.In light gypsum building materials, 90% is all abscess, because capillary effect causes foamed gypsum water-intake rate more than 120%, there is the situations such as flexural deformation after making moist in plastering moisture absorption, causes soft, rotten of construction wall, causes the very serious even recurring structure of strength degradation to cave in; And after abscess is filled by free-water, thermal conductivity sharply rises, it is made to lose heat-insulating property.So although building materials of gypsum has plurality of advantages, the poor problem of its water tolerance seriously constrains its development, and therefore the water resistance research of gypsum building material has become important research direction in the industry.
At present, WATER REPELLENT is carried out mainly through following three kinds of modes: one is at gypsum surface coating or brushing water-proof material; But the method is after defect appears in coated surface or local, exposed gypsum by water-soluble erosion, reduces water resistance when running into water.Be in gypsum, add ground slag or pozzolanic materials on the other hand, improve the melded system of building block; But pozzolanic materials causes the whiteness of plastering to reduce, affect that it is ornamental, and easily cause deuterogenesis to ftracture.The third aspect is admixture water-latex type water-resisting agent in gypsum mainly, improves the water resistance of gypsum; Although the method can keep the decorative effect of gypsum block, can reach again the object of waterproof, in prior paraffin emulsion, acrylic emulsion use procedure, addition content is large, can have a negative impact to the intensity of gypsum.Although the intensity effect of organosilicon waterproof agent for building to gypsum is little, but the Methyl-CpG binding proteins in silicon-type water-resisting agent is water-soluble in a large number, not strong with base material binding ability, very easily run off along with the large quantity of moisture in plastering production process, and then cause the decline of gypsum water resistance.
Summary of the invention
The present invention is to solve for the deficiencies in the prior art, provide a kind of preparation method of the Organic-inorganic composite water-resisting agent for exterior wall building materials of gypsum, its weight composition and preparation method as follows:
Described emulsifying agent is the one in tween-80, Arlacel-80 or OP-10 emulsifying agent.
Nano SiO 2 particle is immersed in methyl methacrylate monomer, silica dioxide granule is fully infiltrated, stand-by.To in the polyvinyl alcohol dissolved, add the silica dioxide granule and polymethylmethacrylate that fully infiltrate, add ammonium persulphate after stirring, tween-80, be warming up to 70 DEG C, continue to stir and the 2h that refluxes, add ammonium persulphate and be warming up to 85 DEG C, stopping heating after half an hour, in time cooling to 50 DEG C, add dibutyl phthalate to stir, cool.
This law is bright by organic materials and the composite water-proof emulsion prepared of inorganic polymer, combines that organic materials cohesiveness is good, erosion resistance is strong, the fine and close waterproof of film and inorganic materials is ageing-resistant, anti-pollution, hardness of film high.Significantly can not only strengthen the water resistance of plastering, more can demonstrate excellent physical and mechanical property.
