Epoxy floor paint performance characteristics and application scope
In the middle and late of the last century, many clean workshop floors began to appear in Europe and the United States. It uses a monolithic polymer surface layer called epoxy floor paint. The main components are epoxy resin and curing agent.
Epoxy floor paints can be divided into two types: solvent-based and solvent-free. Solvent-based epoxy floor coatings emit a certain amount of volatile organic compounds (VOC) during production, construction, and curing, but the cost is relatively low. Solvent-free epoxy floor coatings meet the concept of environmental protection.
Performance characteristics and application scope
Epoxy floor paint has strong acid-alkali resistance, abrasion resistance, pressure resistance, impact resistance, mold resistance, waterproof, dustproof, anti-slip, anti-static, electromagnetic wave and other characteristics, bright and diverse colors, easy to clean. Widely used in electronics factories, machinery factories, hardware factories, pharmaceutical factories, automobile plants, hospitals, aviation, aerospace bases, laboratories, offices, supermarkets, paper mills, chemical plants, plastic processing plants, textile mills, tobacco plants, Confectionery factories, wineries, beverage factories, meat processing plants, parking lots and other surface coatings.
First, choose
Epoxy floor in the end to choose what? Experts said that their strengths can not be neglected. Solvent-based epoxy floor paint is an ordinary epoxy floor paint, suitable for places requiring wear resistance, corrosion resistance, oil resistance, heavy pressure, smooth surface, easy to clean, such as parking lots, automobile manufacturing, machinery manufacturing, High standard ground for workshops in the papermaking, cigarette, chemical, textile and furniture industries.
The solvent-free epoxy floor coating is a floor cleaning material with a high degree of cleanliness. The surface is smooth and clean, can meet the high cleanliness requirements, and is mostly used in self-leveling construction. It is widely used in medicine, food, electronics and precision instruments. , automobile manufacturing and other industries that have extremely high demands on the ground
Second, the advantages
Experts said that solvent-based epoxy floor paint has the following advantages: overall seamless, easy to clean, do not collect dust, bacteria; smooth surface, rich colors, can beautify the working environment; the ground is non-toxic, in line with health requirements; with anti-skid The ground of the parking lot must have a certain degree of roughness. Generally, the cement floor is difficult to meet the requirements.
The solvent-free epoxy floor coating has the following advantages: high bonding strength with the base layer, very low shrinkage when hardened, not easy to crack; overall seamless, easy to clean, do not collect dust, bacteria; high solid content, a film thickness Solvent-free, low toxicity, environmental protection; high strength, wear resistance, durability, can withstand rolling for a long time forklifts, carts and other vehicles; anti-infiltration, chemical corrosion resistance, oil The class also has a good tolerance; room temperature curing film, easy maintenance; smooth surface, rich colors, can beautify the working environment, the ground is non-toxic, in line with health requirements.
Third, the type
Epoxy floor paint can be roughly divided into: thin coating type epoxy floor, epoxy mortar floor, epoxy self-leveling floor, epoxy antistatic floor, garage ramp dedicated floor, epoxy glass fiber floor , anti-corrosion floor and other personalized products: epoxy sand floor, epoxy marble floor, high temperature fire floor, sports floor and so on.
Fourth, characteristics
Epoxy Floor Paint Since the main film-forming base material is epoxy resin, epoxy resin itself has thermoplasticity, it needs to react with curing agent or fatty acid, cross-linked into macromolecular network structure, from its own thermoplastic into Thermosetting, thus showing a variety of excellent performance. Epoxy floor coatings are many and their properties are different.
1. Excellent adhesion: Epoxy floor coating has many hydroxyl and ether bonds, so it can be adsorbed with the bottom material. Moreover, when the epoxy resin is cured, the volume shrinkage is low (only about 2%), so the paint film has excellent adhesion to metal (steel, aluminum), ceramics, glass, concrete, wood and other polar substrates.
2. Excellent chemical resistance: Epoxy resin has only hydrocarbon group and ether bond, no ester bond, so the alkali resistance is particularly prominent, and general oily or alkyd anti-rust primer. In the case of corrosion, the cathode site is alkaline and will be destroyed by saponification. Epoxy floor coatings are alkali-resistant and have good adhesion, so they can be used in large quantities as anti-corrosion primers. Because epoxy paint is cured, it has a three-dimensional network structure after being cured, and can be impregnated with oil. It can also be widely used for anticorrosion of oil tanks, oil tanks, and aircraft's overall tank inner wall linings.
3. Good toughness: Compared with thermosetting phenolic resin coatings, epoxy floor coatings contain aromatic rings and are hard, with ether bonds to facilitate the rotation of the molecular chains, have a certain toughness, unlike phenolic resin is very brittle (because of its cross-linking The spacing is shorter than epoxy. Epoxy resin has a long cross-linking distance and facilitates internal rotation. The greater the molecular weight of the epoxy resin, the greater the cross-linking distance.
4: Epoxy resin has a certain wetting force on the wet surface, especially when polyamide resin is used as a curing agent, it can be made into underwater construction coating and can be applied to the surface of the object to be coated and can be used in underwater structures. Repair and corrosion protection of underwater structures.
5: The molecular weight of epoxy resin itself is not high, can be combined with various curing agents to produce solvent-free, high solids powder coatings and water-based coatings, in line with environmental requirements, and can obtain thick film coating.
6: Epoxy resin contains two reactive groups: epoxy group and hydroxyl group. It can be combined with polyamines, polyamide resins, phenolic resins, amino resins, polyisocyanates, etc. to make a variety of coatings, which can be dried at room temperature and high temperature Baking to meet different construction requirements.
7: Epoxy resin has excellent electrical insulation properties and can be used to seal and dip paint. Epoxy resins have many advantages, but there are also disadvantages, and their photoaging properties are poor. Epoxy resin contains aromatic ether bonds, and the film is easily degraded after exposure to sunlight (ultraviolet rays), so outdoor weatherability is poor. Therefore, the common bisphenol A epoxy resin is not resistant to outdoor sun exposure, and the paint film is easily discolored and discolored, and then it is powdered and should not be used as an outdoor finish.
Five, classification
Solvent-based epoxy floor paint is suitable for places that require abrasion resistance, corrosion resistance, oil resistance, heavy pressure resistance, smooth surface, and easy cleaning, such as parking lots, automobile manufacturing, machinery manufacturing, papermaking, cigarettes, chemicals, textiles, furniture And other industries produce high standards on the ground. Solvent-based epoxy floor has the following advantages: overall seamless, easy to clean, do not collect dust, bacteria; smooth surface, rich colors, can beautify the working environment; the ground is non-toxic, in line with health requirements; with anti-skid, parking The ground must have a certain degree of roughness. Generally, the cement floor is difficult to meet the requirements.
Solvent-free epoxy floor paint is used as ground decoration material with high cleanliness. The surface is smooth and clean, it can meet high cleanliness requirements. It is mostly used in self-leveling construction and widely used in medicine, food, electronics and precision.
