Problems solved by technology

However, since phosphorus-based (phosphate ester, etc.) flame-retardant PC resins and flame-retardant PC / ABS alloys have a large amount (several % to more than 10% by weight) of phosphorus-based flame retardants added, there are some problems : Gas evolution may occur during mold injection molding, and when recycled or placed under accelerated degradation conditions (for high temperature and humidity), the physical properties of the resin decrease significantly; these problems can be attributed to phosphorus-based resistive Combustion agent hydrolyzes PC components, especially under high temperature and high humidity conditions
[0005] However, the flame retardant resin disclosed in the above technical scheme can only reach the B2 level, and the performance parameters of the product after gluing help static bending strength, internal bonding strength and elastic modulus are difficult to achieve the desired effect

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a flame-retardant resin and a preparation method thereof. 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. However, since phosphorus-based (phosphate ester, etc.) flame-retardant PC resins and flame-retardant PC / ABS alloys have a large amount (several % to more than 10% by weight) of phosphorus-based flame retardants added, there are some problems : Gas evolution may occur during mold injection molding, and when recycled or placed under accelerated degradation conditions (for high temperature a...
