Solvent-free anti-static self-leveling floor coating advantages

Solvent-free antistatic epoxy self-leveling floor coating is a high-performance anti-static functional coating that is formed into a concrete floor by self-leveling construction method with epoxy resin as a film-forming material, meeting modern technology and production development. The requirements for the floor are widely used in electronics, computers, aviation, telecommunications, petroleum, medicine and other fields.

     The advantages of solvent-free anti-static self-leveling floor coatings are:
     First, it is highly clean. The floor is required to be corrosion-resistant, clean and wear-resistant, and the indoor air dust content is as low as possible. This performance not only improves the demand for working conditions, but also guarantees the quality of the product;
     Second, eliminate static buildup. Because the floor is often subject to friction, it is easy to accumulate a large amount of static charge, which hinders production operations, interferes with the operation of precision instruments and affects the precision of product processing, and even causes accidents such as fires and explosions. Unlike solvent-based antistatic epoxy floor coatings and waterborne antistatic epoxy floor coatings, solvent-free antistatic epoxy self-leveling floor coatings are characterized by: no voc emissions, environmentally friendly; excellent antistatic effect and long lasting The surface resistance and volume resistance reach 106～108ω; the self-leveling property is good, the construction is simple; the coating film is tough, wear-resistant, chemical-resistant, non-toxic, and non-combustible; the surface of the coating film is smooth and clean, and has good decorative properties. Meets Class 100 cleanliness requirements.

Epoxy resin has the characteristics of good mechanical properties, high bonding performance, low curing shrinkage and good comprehensive performance. It is the most widely used synthetic resin for floor coatings.

Epoxy curing agent is one of the main factors affecting the surface condition of self-leveling floor coating. For this purpose, a modified alicyclic amine curing agent with low viscosity, extremely light color and suitable curing speed is synthesized. The film has the advantages of high surface gloss, good water resistance, good chemical resistance and high mechanical properties.
    At the same time, depending on the regional climate and seasonal differences, different types of curing agents or curing systems are selected to adjust the product to an optimum point to ensure construction quality and product performance.
Conductive materials commonly used in conductive coatings include metal-based fillers, carbon-based fillers, metal oxide-based fillers, and composite conductive fillers, etc., and have excellent antistatic effects.
    In addition, in order to obtain suitable viscosity and improve leveling, 2% to 3% of environmentally-friendly non-reactive epoxy resin toughening thinner is added to the formulation system, which is slowly released during the curing process of the coating film, and has an improved epoxy. The role of resin toughness.
    Epoxy resin, pigment, filler, active and non-reactive diluents, additives, etc. are mixed and stirred uniformly, ground to a certain fineness on a three-roll mill, conductive powder is added, and uniformly dispersed to obtain a main agent; The agent and the equivalent curing agent are uniformly mixed, that is, the self-leveling construction can be carried out by means of smearing.
