Epoxy floor paint factory direct sales

Epoxy floor paint is a modern industrial floor made from epoxy resin paint. It was discovered and put into production and use in Germany in the early 1900s. After years of development, it was introduced to China in the late 20th century. After years of development in China, it was Century popularized in China.
Characteristics of epoxy floor paint
The most demanding epoxy floor coatings used in the coating industry are water-based coatings, powder coatings and high-solid coatings, which are usually used in fields such as automobiles, ships, brains, and handicrafts.
Chemical resistance
Select a polyamine adduct curing agent with a molar mass of active hydrogen of Resin, Epoxy Equivalent, Epoxy Functional Square Novolac Epoxy Resin, Epoxy Equivalent, Epoxy Functional Square Novolac Epoxy Resin, Epoxy Equivalent, Epoxy Functional Square Novolac Epoxy Resin, Epoxy Equivalent, epoxy functional formula is composed of bisphenol type epoxy resin, para-aminophenol epoxy resin (mass ratio), epoxy equivalent, epoxy functional formula. Due to the high epoxy functionality, cross-linking of the cured coating film It has high density and outstanding chemical resistance. However, because the amino nitrogen atoms in the coating are easily attacked by acids, the acid resistance is poor. It is worth noting that only phenolic epoxy resin coatings have slightly better acid resistance and methanol resistance. .
Media permeability prevention
Common gas and liquid corrosive permeability media (referred to as media) have strong penetration capabilities into the coating film. Epoxy resin coatings have excellent media penetration resistance capabilities and are fast and Accurately predicting the resistance to medium permeability of epoxy coatings has attracted people's attention. The relationship between the solubility parameter of the solvent (referred to as the solubility parameter) and the damage to the epoxy coating. The permeability of water vapor and salt water to the epoxy coating and the coating film Research on water resistance, etc. have been reported. Epoxy varnish formula, penetration amount and related parameters. Pour the epoxy varnish liquid prepared from the formula onto the glass plate pre-coated with dilute glue, fully level it, and solidify in The cured sample plate is immersed in ℃ water, and after washing, the free epoxy coating film in ～ is peeled off. Dip-coat the epoxy varnish liquid with the formula ～ on the board, and the first time is cured at ℃, and the second time is cured at ℃, and the result is ~ Fixed epoxy coating film. Use the base material of the formula to adjust the amount of curing agent to prepare epoxy coating films with different effective cross-linking densities. After infrared analysis of the free film and fixed film, it was found that the epoxy groups and active Hydrogen is fully cross-linked and cured. The effective cross-link density epoxy resin and the curing agent are cross-linked and solidified into a network structure coating film. The molar mass between the cross-linking points in the coating film can characterize the chain segment length (or Calculation formula of molar mass between relative molecular mass cross-linking points. The quantitative reflection of the epoxy coating film cross-linking and curing degree, and the qualitative reflection of the pore size of the cross-linking and curing network of the coating film. It is known from calculations and experiments that the value is larger (the value is smaller) The epoxy coating film with a large value has a strong resistance to the penetrating medium penetrating the coating film. The epoxy coating film with the penetrating medium (larger value) has a weak resistance to the penetrating medium penetrating the coating film. The penetrating medium has a weak resistance to the epoxy coating film. The permeability of the membrane is large. When several epoxy coatings of different values are immersed in 2. Relative solubility parameters. When the interaction between the epoxy coating and the permeable medium reaches the maximum value, the permeable medium will be completely destroyed. For epoxy coatings, the penetration amount of the liquid penetrating medium into the epoxy coating film increases with the increase. At that time, the penetration amount of the liquid penetrating medium into the epoxy coating film decreases with the increase.
Physical properties
The main content of the physical and mechanical properties of epoxy coatings is the relationship between the coating structure and tensile strength, hardness, glass transition temperature, peel strength, etc.
Performance of comprehensive factors
Formed by different curing systems Epoxy coatings have different properties. Epoxy coatings have excellent adhesion, chemical resistance, anti-corrosion and water resistance, and some properties are beyond the reach of other coating varieties. Epoxy coating is an indispensable material in many fields. Whether the characteristics of epoxy coatings can be fully displayed depends on factors such as the nature of the structural curing agent of the epoxy resin and the efficacy of various additives in the curing conditions. This is a problem that should be solved when designing the epoxy coating formula
Construction Process folding
Layer treatment polishes off the loose layer delamination and cement residue to make it hard and flat, and increase the adhesion between the floor coating and the ground.
After the epoxy sealing primer is prepared, apply it with a roller, scraper or brush to fully wet the concrete and penetrate into the inner layer of the concrete.
Coating construction: Mix the mid-coating material and an appropriate amount of quartz sand thoroughly, stir evenly, and use a trowel to apply a flat and dense layer of a certain thickness.
The surface coating material is batch-coated with quartz fine powder to fill the gaps between the larger particles of the mid-coat. After it is completely solidified, use a dust-free grinder to polish the ground, and use a vacuum cleaner to absorb the dust and smooth it.
Coating Construction After mixing the epoxy paint and curing agent evenly, you can apply it with a trowel, brush, roller or spray to level it and obtain a smooth and uniform surface coating.
