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 signifi...

Abstract

The invention discloses a flame retardant resin and a preparation method thereof, and relates to the technical field of polymer composite materials. The flame retardant resin comprises following raw materials: styrene dichloride, maleic anhydride, tetrachlorophthalic anhydride, neopentylene glycol, methyl methacrylate, polyester fibers, copper naphthenate, cobalt iso-octoate, calcium carbonate, silica, urotropine, perlite powder, aluminosilicate, graphite, diammonium phosphate, magnesium hydroxide, and aluminum hydroxide. The flame retardant performance of prepared flame retardant resin can reach the B1 level; the static bending intensity of a coated product can reach 20 MPa or more, the inner binding strength can reach 0.6 MPa or more, the elastic modulus can reach 2300 MPa or more and isgreater than the national standard, the performance is excellent, and the market prospect is good.

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...
