Abstract
The invention relates to a premixed flame-retardant antibacterial radiation-proof multifunctional water-based coating which comprises the raw material components: water-based premixed resin, a levelling agent, a wetting agent, a defoaming agent, a thickening agent, a multifunctional additive, nano color paste, a filler and deionized water, wherein the water-based premixed resin comprises melaminederivative modified water-based polyester flame-retardant resin, self-flame-retardant antibacterial water-based polyester resin, rare earth modified water-based polyester resin and a special coalescing agent. According to the prepared premixed flame-retardant antibacterial radiation-proof multifunctional water-based paint, a flame retardant, an antibacterial agent and a radiation-proof agent do not need to be additionally added; the coating has the advantages of good flexibility, good fullness, good flame retardancy, good antibacterial property, high radiation resistance, high crosslinking density, good temperature resistance, good chemical resistance and no pollution, and can be used for decorating and protecting various surfaces of cement concrete, metals, plastics, wood and the like.
Description
technical field [0001] The invention relates to the preparation of a water-based premixed resin, and a premixed flame-retardant, antibacterial, anti-radiation and multifunctional water-based paint for various surfaces such as cement concrete, metal, plastic, wood, etc., which belongs to the synthetic water-based resin and water-based function The field of coating technology. Background technique [0002] With the development and progress of society, the improvement of people's living conditions and the pursuit of the concept of environmental protection and healthy life, water-based coatings are more and more popular with consumers due to their advantages of energy saving, environmental protection, health and safety, non-flammable and non-explosive, and very few volatile organic compounds. From architectural coatings to industrial anti-corrosion coatings to special coatings, the materials range from wood materials, plastic products, and the surface of steel structures. The ap...
