Everyone in the epoxy floor paint construction before the best budget, so there are many benefits, can be a good way to avoid some troubles and disputes after. Resin floor paint has a high viscosity and can not be well compatible with epoxy resin. It also has a good adhesion. However, in addition to these advantages, there are still many shortcomings of resin floor paint. The number of man-power, material and machine shift in the construction budget is calculated on the basis of the construction drawing budget, taking into account the factors such as new technology, new technology and reasonable suggestions agreed by the construction unit and the design unit. Therefore, the construction budget should be accompanied by relevant technical measures and rationalization proposals to ensure that construction personnel and production workers carry out construction according to these measures to achieve the purpose of reducing costs.
Epoxy flooring products have high viscosity, poor compatibility with epoxy resin, low thermal deformation stability, good adhesion, strength and toughness. They are mainly used in high solid coatings, sealants, adhesives, cable connectors, and ester-cyclic amines, i.e. cyclic aliphatic ester-cyclic amines, have low viscosity.
Curing agent has light color, good gloss and good color retention. Compared with polyamide, it has good chemical resistance, no whitening of paint, no induction period, but poor toughness and low curing activity. It can be cured only after heating. It can be cured at room temperature only after adding accelerators or modifying conditions. Antiseptic lacquer aromatic amine, mainly isophenylenediamine curing agent, besides simple phenyldimethylamine, can be cured at room temperature. It has some aliphatic structure characteristics and is liquid, while others are solid at room temperature, so it is inconvenient to mix with resin. It usually needs heating to cure. It is mainly used in heating curing process. Fluorocarbon paint can also be used as raw material of modified amine curing agent.
Generally speaking, single polyamines have small molecular weight, strong volatility, high toxicity, high crosslinking density after reaction with epoxy resin, brittleness of cured products and no impact resistance. Generally, single polyamines, especially aliphatic ones, have small molecular weight, strong volatility, high toxicity and high crosslinking density with epoxy resin. Curing of epoxy floor paint is a serious whitening of coatings, and polyamines which can absorb unreacted amount are reduced. The water vapor in the exhaust air makes the surface of the coating sweat. The above shortcomings make single polyamine as curing agent of epoxy floor resin, which limits its application in horizon coatings in order to overcome the brittleness of amine curing agent.
Budget of Oxygen Floor Paint and Viscosity of Resin Floor Paint
Amine curing agents must be further modified in order to obtain non-toxic or low toxicity due to the poor impact resistance, poor weatherability and toxicity of silicone high temperature resistant paint. Amine curing agents and zinc-rich epoxy primers which can be cured in greenhouse conditions generally have excessive molecular weight, higher boiling point and viscosity. The irritation of sports ground to skin and mucosa is greatly reduced. As the curing reaction of additives is generally faster, the mechanical properties and chemical resistance of alkyd paint cured products are better than those of the original. Polyamines are slightly worse.
Polyamide is formed by condensation of a fatty polyamine with fatty acid dimer. Alkyd-acid blending paint is mainly used as curing agent for epoxy floor coatings. The curing agent for polyurethane paint has high molecular weight and high annual value. The curing agent for polyurethane paint has excellent comprehensive ability. Ammonia bond makes it have very good adhesion to various aggregates, very strong peeling resistance and good wettability. The curing process of urethane is through amide reaction.
