Interior wall paint is latex paint for general decoration. Latex paint is emulsion paint, which can be divided into polyvinyl acetate emulsion and acrylic emulsion according to different substrates. Emulsion paint, with water as diluent, is a kind of paint with convenient construction, water washing resistance and good air permeability. It can be mixed with different colors according to different color schemes. Category: water-based interior wall paint, oil-based interior wall paint, dry powder interior wall paint, which is a water-based paint, mainly composed of five ingredients: water, emulsion, pigment, filler and additive.
Interior wall paint is also called interior wall paint, which includes liquid paint and powder paint. Common latex paint and wall paint belong to liquid paint.
The composition of interior wall paint is basically composed of water, pigments, emulsions, fillers and various additives. These raw materials do not contain any toxicity. As for latex paint, ethylene glycol in film forming agent and organic mercury in mildew inhibitor may be toxic.
One is low-grade water-soluble coating, which is made by dissolving polyvinyl alcohol in water and adding additives such as pigments. In order to improve its performance and reduce the cost, various ways have been taken, with many brands, and the more common ones are 106 and 803 coatings. This kind of coating has the advantages of low price, non-toxic, odorless and convenient construction. Because its film-forming material is water-soluble, it always leaves some traces after scrubbing with a wet cloth. Its durability is also poor, and it is prone to yellowing and discoloration. However, its price is cheap, and its construction is also very convenient. At present, its consumption is still higher, and most of them are used for decoration of middle and low grade rooms or temporary rooms.
The second type is emulsion paint, which is made by taking water as the medium, taking the aqueous solution of acrylate, styrene acrylate copolymer, vinyl acetate polymer as the film-forming material, adding a variety of auxiliary ingredients. The film-forming material is insoluble in water, and the water resistance and weather resistance ratio of the film are greatly improved. There is no trace after wet scrubbing, and the film is smooth Highlight and other different decoration types. Due to its less color, similar decoration and insufficient publicity, and much higher price than 106 coatings, it has not been widely recognized. In fact, these two types of coatings are not of the same grade at all. Latex paint is widely used abroad and is a promising interior wall decorative coating.
Third, new powder coatings, including diatom mud, seaweed mud, activated carbon wall materials, are currently more environmentally friendly coatings. Powder coating, directly mixed with water, with special mold construction, is deeply loved by consumers and designers.
The fourth type is water-based porcelain imitation paint, which is exquisite, smooth and elegant in decoration, low in price, complicated in construction technology, and poor in wet rub resistance. Waterborne porcelain like coating (environment-friendly self owned process): it includes calcite powder, zinc white powder, light calcium carbonate, calcium lime powder, which is characterized by that it uses the mixed colloidal solution of water-soluble methyl cellulose and ethyl cellulose as the solvent for mixed powder; The main proportion of components in the porcelain imitation material is: 20-25 parts of calcite powder, 5-15 parts of zinc white powder, 15-25 parts of light calcium carbonate, 15-25 parts of calcium lime powder, 70 parts of distilled water, 0.6 parts of methyl cellulose, 0.4 parts of ethyl cellulose. The water-based porcelain like coating can be mixed with appropriate amount of titanium dioxide in its own process. The water-based porcelain like coating is free of irritating smell and other harmful substances during preparation and construction.
