Waterborne environment-friendly waterproof emulsion and preparation method thereof

Abstract

The invention discloses a waterborne environment-friendly waterproof emulsion and a preparation method thereof. The waterborne environment-friendly waterproof emulsion is prepared from the following components by weight: 260-500 parts of an ethylene-vinyl acetate copolymer emulsion, 80-100 parts of lightweight inorganic sound-absorbing fibers, 20- 60 parts of a mildew inhibitor, 2-10 parts of a bactericide, 2-5 parts of an antifoaming agent, 1-3 parts of an emulsifier, 2-5 parts of a dispersing agent, 15-20 parts of a film forming aid and 150-250 parts of deionized water. According to the invention, since the lightweight inorganic sound-absorbing fiber, the mildew inhibitor and the bactericide are used, the characteristics of sound absorption, noise reduction, sound insulation, fire prevention, insect prevention and mildew resistance are obtained after film formation of the emulsion; the proportion of the inorganic fibers can be adjusted according to market demands in actual productionso as to produce products meeting different market demands; since the emulsion provided by the invention is free of volatilization of organic solvents in use, so the emulsion is safe to construct andgood in environmental protection performance; and a film formed by the emulsion has high tensile strength, strong resistance to aging and chemical corrosion and good mechanical properties.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based environment-friendly waterproof emulsion and a preparation method thereof. Background technique [0002] Coating is a building material with a long history. With the development of society, there are more and more types of coatings. According to reports, indoor coatings are mainly divided into two types: water-based coatings and solvent-based coatings. The main source of pollution is solvent-based paint, and the use of environmentally friendly water-based paint can completely eliminate the worry about paint pollution. Experts from the China Paint Industry Association believe that any solvent-based paint will contain 50% or more of organic solvents. Since most solvent-based paints and organic solvents contain benzene and its compounds, long-term exposure will cause serious harm to the human body. Therefore, more and more people like to choose environmentally friendly and no...

Problems solved by technology

[0004] At present, there are many kinds of waterproof emulsions used on building surfaces in the market, with single functions and uneven quality. Some of them contain harmful substances such as formaldehyde and benzene. Toxic substances, but there are disadvantages such as poor water resistance, weak adhesion, easy foaming and falling off, etc., and the waterproof effect cannot be achieved. Although some building surfaces are waterproofed, they have to be additionally treated for sound absorption and noise reduction according to customer needs. , bringing no small economic and material losses to the owners or enterprises, but also bringing a lot of trouble to customers
