Problems solved by technology

When phosphorus, boron, aluminum, and nitrogen flame retardants are used, the flame retardant effect can only be achieved when the amount is relatively large. Due to the large amount of flame retardants, the mechanical properties of the polymer are seriously affected; while the halogen-containing flame retardant Although the amount of flame retardant is small, it has little effect on the physical and mechanical properties of polymers, but halogen-containing flame retardants will produce a lot of smoke at high temperatures, and even produce toxic smoke. There are great limitations

Abstract

The invention discloses an MXene-based flame-retardant unsaturated resin material, and belongs to the technical field of flame-retardant materials. The MXene-based flame-retardant unsaturated resin material is prepared from the following components, by mass: 75.2 to 94 parts of unsaturated polyester resin, 0 to 20 parts of ammonium polyphosphate and 0 to 0.4 part of an MXene material, and the MXene material can be subjected to modification treatment by using 1-butyl-3-methylimidazolium hexafluorophosphate and a silane coupling agent. The MXene-based flame-retardant unsaturated resin material provided by the invention is further subjected to a cross-linking curing reaction with a curing agent and an accelerant to generate the MXene-based flame-retardant unsaturated resin molding material, and the generated MXene-based flame-retardant unsaturated resin molding material has good flame retardance.

Description

technical field [0001] The invention belongs to the technical field of flame retardant materials, and in particular relates to a Mxene-based flame retardant unsaturated resin material and a preparation method thereof. Background technique [0002] Unsaturated polyester resin is formed by polycondensation of dihydric alcohol and saturated dibasic acid at high temperature, and its main chain contains polymerizable double bonds, which are copolymerized with various vinyl monomers under the action of an initiator to obtain thermal Solid plastic. Unsaturated polyester resin has excellent technological properties such as high strength, light weight, radiation resistance, shock resistance, heat insulation, electrical insulation and microwave transmission, and can be molded under normal temperature and pressure, so it is widely used as paint, putty, adhesive Agents, artificial marble, buttons, corrugated boards, building materials and car casings, etc. However, unsaturated polyest...
