Embodiment 1

[0013] A preparation method of epoxy resin flame retardant board, comprising the steps of:

[0014] Step 1, get the epoxy resin of 53 weight parts, make the epoxy resin particle that diameter is less than 5mm by crusher;

[0015] Step 2, after mixing the epoxy resin particles and 44 parts by weight of organoclay MMT evenly, add 3 parts by weight of aluminum hydroxide;

[0016] Step 3, heating the mixture until it is partially melted, cooling it to 60°C to 80°C, and pressing it into a plate-shaped material;

[0017] Step 4: Put the plate-shaped material in the middle of the steel wire mesh on both sides, and continue to press, so that the steel wire mesh is embedded on the surface of the plate-shaped material, and the epoxy resin flame-retardant board is obtained.

Abstract

The invention relates to a preparation method of an epoxy resin flame-retardant sheet. The preparation method comprises the following steps of 1, taking 53 parts by weight of epoxy resin, and crushing the epoxy resin into epoxy resin particles having the diameter less than 5mm by a crusher, 2, uniformly mixing the epoxy resin particles and 44 parts by weight of organic clay MMT, and adding 3 parts by weight of aluminum hydroxide into the mixture, 3, heating the mixture obtained by the step 2 until partial fusion, cooling to a temperature of 60 to 80 DEG C, and pressing the mixture into a sheet material, and 4, putting the sheet material between two steel wire meshes, and carrying out compression so that the steel wire meshes are embedded into the surface of the sheet material and the epoxy resin flame-retardant sheet is obtained. Through utilization of the organic clay MMT in the epoxy resin, epoxy resin flame retardation is effectively improved. Through utilization of aluminum hydroxide, composite material flame retardation is not influenced and can be improved. Through utilization of the steel wire meshes, material strength is improved. Therefore, the epoxy resin flame-retardant sheet can be widely used in places having a large fire hazard.

Description

technical field [0001] The invention relates to a method for preparing a flame-retardant material, in particular to a method for preparing an epoxy resin flame-retardant board. Background technique [0002] In modern offices and homes, many materials are flammable. Due to the uncertainty of fire, when a fire occurs, many materials will burn. On the one hand, a lot of heat will be generated, and more importantly, many materials will emit toxic gases and smoke, which will increase the danger of fire. [0003] In order to reduce the hazards of fire, many flame retardant materials have been tested or used. However, many flame retardant materials currently face problems such as high cost, poor flame retardant effect, and low mechanical strength, which limit the application of flame retardant materials. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing an epoxy resin flame-retardant board with good flame-retardant effec...
