This kind of coating is characterized by convenient brushing, spraying and construction. Good leveling, fast drying, tasteless, no fire danger, good color retention and scrub resistance. It can also be constructed on the slightly wet foundation wall, which is beneficial to improve the construction progress. Therefore, it is suitable for interior wall decoration of senior residence.
2. Polyvinyl Sodium Silicate Interior Wall Coating This coating is nontoxic and tasteless, with fast drying and smooth surface, which can form a flat coating similar to matte paint and has certain decorative effect; And can be constructed on a slightly wet wall surface, and has the advantage of certain adhesion with the wall surface. However, it has poor water resistance and is easy to peel off, so it belongs to low-grade interior wall coating.
3. Hygienic insect-proof coating
This coating is based on synthetic polymer compounds, mixed with a variety of high-efficiency and low-toxicity pesticides, and then added with a variety of additives according to a specific synthetic process. It has the advantages of bright color, strong hiding power and good wet rubbing resistance. At the same time, it has good contact killing effect on mosquitoes, flies, white mosquitoes, cockroaches and other pests, but it is harmless to human body. Besides being used as interior wall decoration, it is especially suitable for decorating kitchens and food storage rooms.
This kind of coating has been produced by many domestic manufacturers, and the "insecticidal latex paint" made of imported patented technology can be used for 3 ~ 5 years, which is harmless to people and animals. For another example, the "mosquito-killing and fly-killing paint" produced by Datang Building Materials Factory in Hengnan County, Bohai Sea has a good contact killing effect on pests. It is effective in simulating natural experiments in the laboratory for 6 years, but it is harmless to human body.
4. Aromatic interior wall coating This coating is based on polyvinyl alcohol, which is made through a series of chemical reactions, and is processed by adding special synthetic spices, pigments and other additives. It has the characteristics of bright color, fragrant smell, lasting fragrance, rich and non-toxic, fresh air, insect repellent and sterilization. There are jasmine, roses, pine needles and so on.
5. Sound insulation and fire retardant coatings This kind of coating is a water-soluble coating composed of synthetic resin, inorganic binder, high-efficiency, sound insulation and flame retardant materials and chemical additives. It has the characteristics of sound insulation, fire prevention, aging resistance, corrosion resistance, wear resistance, waterproof and good decorative effect.
6. Wood structure fire retardant coating It is an ideal method to treat wood structure materials and wire surfaces with fire hazards in indoor decoration. There are many kinds of commonly used fire retardant coatings. Here are some examples:
(1) Organic-inorganic composite foaming fire retardant coating. This coating is based on the combination of inorganic polymer materials and organic polymer materials.
It has the characteristics of light weight, fire prevention, heat insulation, toughness and brittleness, good decoration and convenient construction.
(2) Organic polymer intumescent fire retardant coating This kind of coating is a one-component water-borne intumescent fire retardant coating with organic polymer as film-forming base material and flame retardant additives and chemical additives added under certain technological conditions.
It has the characteristics of non-toxicity, good flame retardancy, moisture resistance, aging resistance, good color retention and high bonding strength. Especially the expansion and foaming multiple is high. Has good fire prevention effect. The "SJC4 intumescent fire retardant coating" produced by Beijing Tongzhou fire retardant coating factory belongs to this kind of coating.
(3) Acrylic latex intumescent fire retardant coating This coating is made of acrylic latex as adhesive, various fire retardant additives, water as medium, pigments and additives.
Non-flammable, non-explosive, non-toxic, fast construction, fast drying, outstanding fire and flame retardancy, diverse colors, hood, water resistance, oil resistance and aging resistance.
(4) Inorganic polymer fire retardant coating This kind of coating is a water-based coating based on modified inorganic polymer binder and added with flame retardant and chemical additives. It has the characteristics of fire prevention, non-toxicity, convenient construction, good film forming, strong adhesion, high film hardness and good decorative performance. "SJC3 foamed fire retardant coating" produced by Fushun Huaxian building fire retardant material factory belongs to this category.
7. Mildew-proof coating This kind of coating is made of polymer emulsion or potassium sodium silicate as the main film-forming substance, and raw materials such as pigments and fillers, low-toxicity and high-efficiency mildew inhibitors are added.
Non-toxic, odorless, nonflammable, water-resistant, acid and alkali-resistant, dense coating, scrub-resistant, good decorative effect, convenient construction, especially for ten kinds of molds such as Aspergillus flavus. Therefore, it is very suitable for interior wall decoration in humid and moldy environment.
8. Porcelain glaze coating This coating is a bright coating based on a variety of polymer compounds, with various additives and pigments and fillers. It has the characteristics of wear resistance, boiling water resistance, aging resistance and high hardness. After the paint film is bright, smooth and stained, it can be wiped off with soap, washing powder, decontamination powder and other tools such as a brush. Because it has the characteristics of porcelain glaze, it can be painted on the inner walls of bathrooms and kitchens instead of tiles. It can also be coated on sanitary ware made of cement (such as cement bathtub) to make its surface smooth as enamel.
