High-temperature-resistant flame-retardant resin

Abstract

The invention discloses a high-temperature-resistant flame-retardant resin and belongs to the technical field of flame retardance. The high-temperature-resistant flame-retardant resin comprises the following components in parts by weight: 40 to 60 parts of unsaturated polyester resin, 5 to 25 parts of clay fiber, 5 to 25 parts of glass wool, 4 to 8 parts of copper naphthenate, 2 to 6 parts of cobalt iso-octoate, 15 to 35 parts of calcium carbonate, 2 to 6 parts of talcum powder, 2 to 6 parts of polyvinyl fluoride and 6 to 12 parts of silicon dioxide. The high-temperature-resistant flame-retardant resin provided by the invention has the good permeability to various fiber products due to low viscosity and good permeability, and has a long available using period due to adjustable viscosity. Thus, the high-temperature-resistant flame-retardant resin can be widely applied to the processes of mechanical winding, casting, hand pasting, mould pressing and the like. The high-temperature-resistant flame-retardant resin has wide market value and huge market potential.

Description

technical field [0001] The invention relates to the field of flame retardant technology, in particular to a high temperature resistant flame retardant resin. Background technique [0002] With the continuous development of corrosion and protection and the continuous improvement of industrialization, the application fields of composite materials are becoming wider and wider, the working conditions and media are becoming more and more complex, and the operating temperature is getting higher and higher. Also getting higher and higher.

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.
