Flame-retardant smokeless environmentally-friendly glass reinforced plastic coating material and preparation method thereof

Abstract

The invention discloses a flame-retardant smokeless environmentally-friendly glass reinforced plastic coating material. The flame-retardant smokeless environmentally-friendly glass reinforced plastic coating material is characterized by being prepared from the following raw materials in parts by weight: 29-34 parts of E-12 epoxy resin, 14-18 parts of amino resin, 5-8 parts of dioctyl phthalate, 8-11 parts of nanometer aluminum nitride powder, 1-2 parts of cellulose nitrate, 2-3 parts of bismuthyl chloride, 5-7 parts of magnesium hydroxide, 5-7 parts of ethyl methacrylate, 6-8 parts of 4-methoxyphenol, 3-6 parts of diepoxypropane ethyl ether, 20-23 parts of chopped glass fiber, 2-3 parts of nanometer calcium carbonate, 1-2 parts of zinc stearate, 7-10 parts of 2-ethyl-4 methylimidazole and 1-2 parts of additives. The flame-retardant smokeless environmentally-friendly glass reinforced plastic coating material has good physical performance and mechanical performance by adding the additives and plays a role of reinforcement; the flame-retardant smokeless environmentally-friendly glass reinforced plastic coating material has a good flame-retardant effect by adding the magnesium hydroxide and a smoke suppression effect and is non-toxic and environmentally-friendly, so that a glass reinforced plastic material has a relatively good flame-retardant effect.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a flame-retardant, smoke-free and environment-friendly FRP coating material and a preparation method thereof. Background technique [0002] FRP material is a material in which glass fiber reinforced materials are embedded in cured thermosetting resin or wrapped by it to form a composite structure. At present, most of the FRP materials used in the market are formed by resin-impregnated glass cloth materials. The method has a good wetting effect and the prepared glass fiber has a high content. However, due to the limitation of the volume and shape of the glass cloth, it is especially not suitable for products such as pipe joints, tee fittings, and elbow fittings, which are not easy to be uniformly compressed. In addition, the impact resistance of the FRP material prepared by this method is poor, and the laminated surface is prone to delamination. In order ...

AI Technical Summary

Problems solved by technology

Although the FRP material provided by this method overcomes the defects caused by the glass cloth itself, the unique physical properties of the fiber itself are greatly weakened because the glass fiber is cut into powder

[0003] At present, the flame retardant used in FRP composite materials is usually antimony trioxide, which has poor flame retardant effect.

And antimony trioxide products usually contain arsenic oxide, but arsenic oxide is poisonous, so it will pollute the environment during the use of FRP and is not environmentally friendly.
