Flame retardant resin

Abstract

The invention discloses a flame retardant resin. The resin is prepared from, by mass, saturated polyester resin 30-50%, tetrachlorophthalic anhydride 10-20%, carclazyte fiber 5-10%, copper naphthenate5-8 %, cobalt iso-octoate 2-5%, calcium carbonate 10-20%, chlorinated styrene 5-10% and silica 5-10%. The flame retardant resin has no toxicity, long service life of a workpiece, excellent high temperature flame retardant performance and high bonding strength.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a flame-retardant resin. Background technique [0002] At present, the high-performance resin composite materials used in the domestic and foreign fields are relatively single, mainly unsaturated polyester, vinyl ester resin, and tough epoxy resin materials, but these materials have deficiencies to varying degrees; Ester, high brittleness, low use temperature, and low bonding strength; although vinyl ester resin has the advantages of good toughness, good bonding strength, and low toxicity after curing, it has disadvantages such as low use temperature; epoxy resin, although it has toughness Good, high bonding strength, etc., but there are poor weather resistance, easy pulverization, high viscosity, poor wettability, and poor ability to withstand strong corrosive media such as strong acids, alkalis and solvents at higher temperatures. Curing system High toxicit...

[0002] At present, the high-performance resin composite materials used in the domestic and foreign fields are relatively single, mainly unsaturated polyester, vinyl ester resin, and tough epoxy resin materials, but these materials have deficiencies to varying degrees; Ester, high brittleness, low use temperature, and low bonding strength; although vinyl ester resin has the advantages of good toughness, good bonding strength, and low toxicity after curing, it has disadvantages such as low use temperature; epoxy resin, although it has toughness Good, high bonding strength, etc., but there are poor weather resistance, easy pulverization, high viscosity, poor wettability, and poor ability to withstand strong corrosive media such as strong acids, alkalis and solvents at higher temperatures. Curing system Disadvantages such as high toxicity, long curing cycle, and high post-processing costs

Therefore, traditional composite materials are far from meeting the market's increasingly high performance requirements.
