High-temperature-resistant flame-retardant resin

Abstract

The invention discloses a high-temperature-resistant flame-retardant resin which comprises the following components in percentage by weight: 40-50% of unsaturated resin, 5-11% of asbestos fiber, 2.5-4.5% of alumina fiber cotton, 4-8% of 8% copper naphthenate, 1.5-4.5% of 12% cobalt isooctoate, 15-21% of calcium carbonate, 5-9% of talcum powder, 2-4% of accelerator and 5-7% of silicon dioxide. Due to low viscosity and favorable infiltration property, the high-temperature-resistant flame-retardant resin provided by the invention has the advantages of favorable permeation property for various fiber products, adjustable viscosity and long use cycle, can be widely used in mechanical winding, casting, manual pasting, die pressing and other techniques, and has wide market value and great market potential.

Description

technical field [0001] The invention relates to the technical field of polymer materials, more specifically, it is a high-temperature-resistant and flame-retardant resin. Background technique [0002] With the continuous development of corrosion and protection and the 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. The market requirements for its performance are also increasing. Higher and higher. [0003] At present, the materials of high-performance resin composite materials used in 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. Such as unsaturated polyester, high brittleness, low use temperature, and low bonding strength; although vinyl ester...

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 polyester, vinyl 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.
