Problems solved by technology

At present, phosphorus-based products such as BDP, RDP, and TPP are mostly used as flame retardants in halogen-free flame-retardant PC / ABS alloys. Products made with these flame retardants can certainly meet customer requirements in terms of flame retardancy and environmental protection, but Their addition also seriously affects other mechanical properties of PC / ABS alloys, such as impact strength, flexural strength, flexural modulus, heat distortion temperature, etc., especially when the product is used at a higher temperature for a long time, ordinary Halogen-free flame-retardant PC / ABS alloy cannot meet product requirements

The invention also provides a method for preparing the alloy.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant PC / ABS alloy and also relates to a method for preparing the alloy. Background technique [0002] In recent years, with the development of electronic products and people's attention to the ecological environment, PC / ABS alloy, which is used as the shell material of electronic products, has encountered more and more challenges. The general requirement of PC / ABS alloy is to have halogen-free flame retardant performance, which not only reduces the fire hazard of the product during use, but also reduces the impact of the product on the environment. At present, phosphorus-based products such as BDP, RDP, and TPP are mostly used as flame retardants in halogen-free flame-retardant PC / ABS alloys. Products made with these flame retardants can certainly meet customer requirements in terms of flame retardancy and environmental protection, but Their addition also seriously affects other mechanical properties ...
