Flame-retardant resin

Abstract

The invention discloses flame-retardant resin, belonging to the technical field of high polymer materials. The technical scheme of the invention is as follows: the flame-retardant resin is composed of the following components in parts by weight: 25-60 parts of unsaturated polyester resin, 5-25 parts of glass wool, 2-10 parts of copper naphthenate, 1-5 parts of cobalt iso-octoate, 15-35 parts of calcium carbonate, 1-5 parts of talcum powder, 1-5 parts of polyvinyl fluoride, 6-14 parts of silicon dioxide, 2-12 parts of clay fiber, 2-12 parts of asbestos fiber, 2-10 parts of alumina cellucotton, and 2-6 parts of accelerant. Compared with the prior art, because the flame-retardant resin provided by the invention is low in viscosity and good in infiltrating property, the flame-retardant resin has a good penetration property to various fiber products; moreover, the flame-retardant resin is adjustable in viscosity and long in service life, therefore, the flame-retardant resin can be widely applied to processes of mechanical warping, casting, manual lay-up, mould pressing and the like, and has broad market values and huge market potential.

Problems solved by technology

[0003] At present, the materials of high-performance resin composite materials used in domestic and foreign fields are relatively single, mainly unsaturated polyvinyl ester resin and tough epoxy resin materials, but these materials have deficiencies to varying degrees.

Such as unsaturated polyester, 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 the advantages of good toughness and high bonding strength, it has poor weather resistance, easy pulverization, high viscosity, and poor wettability. Poor, the curing system is highly toxic, the curing cycle is long, and the post-processing cost is high.

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