The floor coating was first invented in Germany in 1934 and is mainly made of oil, tree, color, solvent and so on. Modern industry has put more and more strict requirements on the floor. For example, food, medicine and other industries require that the floor be ash-free, no harmful volatiles, clean and dust-free; the machinery industry requires strong mechanical shock resistance, wear resistance, and energy. Long-term exposure to vehicles such as forklifts, even partial damage is easy to repair; machine tools, instrumentation and other industrial workshops are often exposed to various oil erosion, difficult to completely remove, requiring good oil resistance of the floor, the chemical industry requires Ping can withstand the corrosion of various chemical media. In addition, modern civilized workshops and family floors should be flat, bright and colorful, creating a good working and living environment for people. Therefore, with the rapid development of coating technology, the existence of floor coatings has its necessity and inevitability, and different application requirements have led to the diversity of floor coatings.
Waterborne floor coating classification
According to the main film-forming materials of the floor coating, the floor coating products mainly include the following: epoxy floor coating, polyurethane resin floor coating, unsaturated polyester resin floor coating, acrylic floor coating, crystal. Floor coatings, polyurea elastomer floor coatings, concrete seal curing agents, etc.
Functionally classified, specialized floor coatings are derived from a variety of functional categories, such as decorative floor coatings with crystal flooring, colored sand epoxy, etc.; elastic flooring with Tebon rubber flooring, rubber cushion composite flooring Wait.
Variety and introduction
The main function of the paint is to decorate and protect the indoor floor, making the floor clean and beautiful, creating an elegant indoor environment for people. The floor coating should have the following characteristics: good alkali resistance, because the ground paint is mainly applied on the base layer of cement mortar with alkaline; it has good adhesion with cement mortar; it has good water resistance and scrub resistance; Good wear resistance; good impact resistance; convenient brushing construction; reasonable price. The varieties of floor paints are as follows:
Perchloroethylene floor coating
Good aging resistance and waterproof performance, fast drying of paint film (2 hours), certain hardness, adhesion and wear resistance, impact resistance, rich colors, no irritating odor after drying, no harm to human health. The coating is suitable for the decoration of concrete floors such as residential buildings and physical laboratories.
H80-epoxy floor coating
It has good corrosion resistance, hard coating, wear resistance and certain toughness. The coating has strong adhesion to cement base layer, oil resistance, water resistance, heat resistance and dust resistance. It can be painted into various patterns. Applicable to the ground decoration of abrasion, dust, acid, alkali, organic solvent and water resistance in airports and industrial and civil buildings.
Polyurethane floor coating
The coating is a high solid thick coating, which has excellent corrosion resistance and insulation properties, especially a comprehensive acid and alkali resistant property, high strength and elasticity, and a base surface for metallic and non-metallic concrete. Has a good adhesion. The painted floor is smooth and non-slip, with good elasticity, wear resistance, pressure resistance, water resistance, beautiful appearance, comfortable walking, no dust, easy cleaning, good self-extinguishing, no discoloration during use, no waxing required. Used instead of carpet, but the price is more expensive. It is suitable for flexible decorative floor in occasions such as conference rooms, auditing halls, libraries, etc.; wear-resistant, oil-resistant and corrosion-resistant floors of industrial workshops, workshops and precision machine rooms, and waterproof decorative floors for basements and bathrooms.
Chlorine-biased copolymer emulsion floor coating
A water-milk emulsion prepared by adding a filler such as a vinyl chloride copolymer emulsion to a filler or a pigment. It has the characteristics of odorless, quick drying, non-combustible and easy to construct. The coating is firm and smooth, has good moisture resistance, mildew resistance, acid resistance, alkali resistance and chemical stability. It is widely used for floor coatings in institutions, shops, hotels, warehouses, factories, enterprises and public places. It can be used to imitate wood floors, flower patterns, marble, ceramic tiles and other colored floors.
Polyvinyl formal cement floor coating
Also known as 777 water-based floor coating, it is characterized by non-toxic, non-combustible, coating and cement base layer combined fastening, drying fast, wear-resistant, water-resistant, no sand, no cracks, can be painted on several layers of wet cement, The construction is convenient, the color is bright, the appearance is smooth, the price is cheap, the durability is good, and the decorative effect is good. Suitable for construction, residential and general laboratories, offices, new and old concrete floor decoration. It can be imitated as squares, fake wood grain and various geometric patterns on the ground.
Polyvinyl acetate cement floor coating
Also known as HC-floor coating, it is composed of polyvinyl acetate as the base material plus inorganic pigments, various additives, quartz powder and ordinary Portland cement. It is an aqueous polymer cement coating. Its characteristics are non-toxic, non-combustible, fast drying, strong bonding, wear resistance, impact resistance, elastic feeling, good decorative effect, simple production process, convenient construction and low price. It can be used for civil and other building floors, and can replace some terrazzo and plastic floors, especially suitable for the renovation of old cement floors.
