Problems solved by technology

[0003] Commonly used flame retardant and fireproof coatings are mostly self-drying paints, but there are some common problems. Generally, flame retardant and fireproof coatings need to be coated with 2 to 3 layers, and the interval between each layer is 6 to 8 hours. It takes a few days to completely dry. There will also be a large amount of volatile organic compounds (VOC) emissions, but UV curable coatings are fast curing and have good performance, and there is no or very little volatile organic compounds (VOC) emissions during the curing process.
At present, the flame-retardant and fire-resistant coatings on the market can only meet the requirements of flame-retardant and fire-proof by adding a large amount of flame-retardant and fire-proof powder. However, the addition of a large amount of powder will inevitably affect the transparency of the coating film and make its material The color of some patterns becomes blurred, which greatly affects its appearance
Adding inorganic powder makes its viscosity larger. To meet the construction requirements, it is necessary to increase the amount of monomers, thereby increasing the proportion of monomers. There is a certain amount of organic volatiles (VOC) in the monomers, thereby increasing organic volatiles. (VOC) emissions
At the same time, adding inorganic powder will greatly reduce the transparency, and the penetration of ultraviolet light will be greatly affected during the UV curing process, so that the bottom curing speed of the coating will be greatly reduced.

Abstract

The invention discloses a UV cured transparent and flame-retardant coating. The UV cured transparent and flame-retardant coating comprises components in part ratios by weight as follows: 40-70 parts of phosphorus modified epoxy acrylate resin, 25-55 parts of a reactive diluent, 1-5 parts of a photoinitiator, 0.1-1 part of a leveling agent, 0.1-1 part of an antifoaming agent and 0.01-0.1 parts of a polymerization inhibitor, wherein the phosphorus modified epoxy acrylate resin is one of phosphorus modified bisphenol A epoxy acrylate resin and phosphorus modified phenolic epoxy acrylate resin or combination of the phosphorus modified bisphenol A epoxy acrylate resin and the phosphorus modified phenolic epoxy acrylate resin in any ratio. The UV cured transparent and flame-retardant coating can realize the flame retardant effect effectively, adopts UV curing and has the advantages of high transparency, rapid curing, environmental protection, avoidance of toxicity, good adhesion, scratch resistance and the like.

Description

technical field [0001] The invention relates to a flame-retardant fireproof coating. Background technique [0002] Fire not only brings light and warmth to human beings, but also an important symbol of human society from primitive to civilized, but fire is also one of the major dangers of human beings. Fire causes huge personal and property losses to human beings. In order to prevent fire accidents, prevent Combustible and fire-resistant coatings are an effective flame-retardant and fire-resistant measure in buildings and combustible materials. They not only have decorative effects, but more importantly, they have the function of flame-retardant and fire-proof. [0003] Commonly used flame retardant and fireproof coatings are mostly self-drying paints, but there are some common problems. Generally, flame retardant and fireproof coatings need to be coated with 2 to 3 layers, and the interval between each layer is 6 to 8 hours. It takes a few days to completely dry. There wil...
