First, the practice of epoxy floor paint
1. To say what is the method of epoxy floor paint, we must first use epoxy resin. Epoxy resin is the main component of epoxy floor paint, and it is also the hardness and wear resistance of epoxy floor paint. It is also the source of mankind.
2. A curing agent is actually used as a curing agent. Curing agents commonly used in floor paint engineering include 593 curing agent, T3 1 curing agent, 65 1 curing agent, 8 10 curing agent, ketoimine curing agent and NX-2040 curing agent.
3. Next, discuss solvents: there are two kinds of solvents for floor paint: solvent-based and solvent-free, and solvent-based floors need solvents.
4. Pigments and fillers are also needed, among which pigments and fillers are pigments and fillers. Pigments of epoxy floor coatings include titanium dioxide, iron oxide red, iron oxide green, iron oxide black, iron oxide yellow and so on. Fillers used for floor coatings include barium sulfate, mica powder, talcum powder and quartz powder.
5. Distributed system is one of them. Dispersant molecules are hydrophilic and lipophilic and can separate insoluble substances from liquids.
6. Defoamer is an essential product. It is an assistant for removing bubbles from epoxy floor, which makes the film wall of bubbles thinner and brittle and can solve the foaming problem of epoxy floor.
Second, the characteristics of epoxy resin floor paint
1. Excellent adhesion: Epoxy floor paint has many hydroxyl and ether bonds and can be adsorbed by alkaline substances. In addition, the volume shrinkage of epoxy resin after curing is low, so the paint film has good adhesion to polar substrates (such as metal, ceramics, glass, concrete, wood, etc.).
2. The epoxy floor has a constant wetting force on the wet surface, especially it can be made into submerged structure coating, especially when polyamide resin is used as curing agent. Structural repair and corrosion protection of underwater structures.
3. Epoxy floor itself has no high molecular weight, and can be used with various curing agents to produce solvent-free high-solid powder coatings and water-based coatings, which can not only meet the requirements of environmental protection, but also obtain thick film coatings.
4. The bottom of epoxy resin contains two active groups, epoxy group and hydroxyl group. Through the combination of polyamine, polyamide resin, phenolic resin, amino resin and polyisocyanate, it can be dried at room temperature to make various coatings, and baked at high temperature to meet various architectural requirements.
5. Special concrete sealing curing agent for polishing concrete floor can be provided. The diamond ground consists of Lu Na special cement mortar, Lu Na special reinforced concrete seal curing agent and Lu Na special steel wire concrete. Composed of three materials, it can make the site seamless, low-carbon, energy-saving, environmentally friendly, wear-resistant, waterproof and non-slip.
The above is a detailed introduction to the practice and characteristics of epoxy floor paint in this paper. In this small series, it is especially recommended that when choosing, choose the one with less formaldehyde and benzene, and the pungent taste is wrong, because life safety is everyone's first priority. If.
