Floor paint manufacturers share knowledge of floor paint
Floor paint, I believe we are no strangers. For example, factories, schools, hotels, hospitals, office buildings, residential quarters, shopping malls and buildings and other ground and underground parking floors are often seen. How much do you know about it? Floor paint manufacturers now come to share relevant knowledge for you.
ã€Basic overview of floor paint】
Floor paint is made up of many different materials, such as mixing, dissolving, dispersing and many other production processes. According to the different effects of various components of floor paint, it can generally be divided into main film materials, secondary film-forming materials and auxiliary film-forming materials. The self-leveling properties mentioned in floor paints mainly refer to topcoats, and primers and intermediate coats are of the same type as other floorings. The quality of self-leveling paint is the key to the apparent effect and use effect of epoxy self-leveling floor. Construction epoxy self-leveling paint, mainly in the form of a trowel scraping, gently driving the self-leveling paint through the toothed side of the trowel, to create a little power, and then let the self-leveling paint self leveling. In construction, temperature, construction methods, and construction techniques directly affect the effect of epoxy self-leveling flooring.
What is the composition of floor paint?
1, the main base material
(1) Polyurethane resin: It is a thermoplastic polymer containing hydroxyl groups of isocyanate and polyester, polyether, epoxy resin, castor oil or its processed product (oxidation polyhydrazine glycerol alcoholysis) ( Such as B-hydroxyethyl containing polyacrylate resin, hydroxyl-containing chloroacetic copolymer resin) cellulose acetate butyrate and other formulations, made of many types of polyurethane coatings. If TDI or MDI is used with polyether, it is the main base material of elastic floor coating; HDI is used together with B-hydroxyethyl-containing polyacrylic acid resin, and it is the base material for high-grade flooring coatings.
(2) Epoxy resin: When the epoxy resin is used for floor coating, the epoxy resin is applied on the floor with seamless floor coating material, and the water-emulsion type exterior wall coating is the main binder.
2. Secondary film forming substances
The secondary film-forming substance is also an important constituent of the coating film, but it cannot leave the main film-forming substance alone as a coating film. This ingredient is the pigment used in the paint. The addition of pigments to the coating not only improves the coating performance, but also increases the variety of coatings.
3, auxiliary film forming material
1. Auxiliary film-forming substances cannot form a coating film or a main part of the coating film, but have a great influence on the film-forming process (construction process) of the coating, or play a role in the performance of the coating film.
(2) Auxiliary materials: Film-forming substances, pigments, and solvents constitute coatings. However, in order to improve the performance, some auxiliary materials are often used. The auxiliary materials used in the coatings are many and each has special features, but the amount is small. It is usually several to several thousandths or less. Although the amount is small, but the effect is significant. According to the function of auxiliary materials, it can be divided into driers, plasticizers, wetting agents, UV absorbers and so on. With driers, there are more plasticizers used. The following is a description of the composition, characteristics or use of floor paints.
ã€Introduction to floor paint types】
1. Epoxy floor paint: It is usually composed of epoxy resin, solvent and curing agent, and pigments and auxiliaries. This kind of coating contains many types of floor paint, such as solvent-free self-leveling floor paint, anti-corrosion floor paint. , Wear-resistant floor paint, anti-static floor paint and water-based floor paint, etc., Its main features are strong adhesion to the cement base layer, the ability to resist water and other corrosive media and has a very good coating physical mechanics Performance and so on. Adapt to various factories, repair fields, stadiums, parking lots, warehouses, shopping malls and other ground locations. Two-component epoxy sealing varnish made of epoxy resin, modified curing agent, solvent, etc. The concrete base surface has high permeability and greatly increases the strength of the concrete base surface. Excellent alkali resistance, good adaptability of concrete base. The high bond strength with the concrete base surface can effectively resist the back pressure caused by water vapor. Suitable for closed primer for putty, masonry and concrete structures. It can also be used for the sealing of hot spray zinc, aluminum spraying and inorganic zinc-rich coating.
2, polyurethane floor paint: polyether resin, polyether resin, acrylic resin or epoxy resin as a component, due to coating film hardness and adhesion to the grass-roots layer as epoxy paint, its varieties less. Mainly used for flexible floor paint and non-slip floor paint places.
3, anti-corrosion floor paint: In addition to a variety of strength properties with load-bearing floor paint, but also able to withstand the corrosive effects of a variety of corrosive media. Adapted to all kinds of chemical plants, kerosene plant, sanitary materials factory floor coating.
4, flexible floor paint: made of flexible polyurethane, coating film because of its flexibility and walking comfort. Adapted to a variety of sports venues, public places and some factory floor ground coating.
5, anti-static floor paint: can discharge electrostatic charge, prevent accidents due to static electricity accumulation, as well as shielding electromagnetic interference and prevent the adsorption of dust, etc., can be used for a variety of antistatic ground coating. Adapted to the power plant, electronics factory workshop, pyrotechnic product factory, computer room, etc. 6, non-slip floor paint: coating has a high coefficient of friction, non-slip properties, for a variety of non-slip requirements of the ground coating, is a The class is in a good application phase of rapid application and development. Used for all kinds of floors with anti-slip requirements.
6, can load floor paint: This type of floor paint and concrete base bond strength, tensile strength and hardness are high, and has a good impact resistance, bearing capacity and wear resistance. Suitable for flooring applications such as factory floors and warehouses where trucks and forklifts are required.
The above about floor paint is introduced here today. For more information, please continue to pay attention to us.
