Abstract

The invention provides a PA6 flame retardant plastic, and relates to a plastic. The PA6 flame retardant plastic is prepared from aluminum hydroxide and a diethyl aluminum phosphinate composite environmental-protection flame retardant agent, and comprises, by weight, 100 parts of a PA6 resin, and 40-75 parts of a composite environmental-protection flame retardant agent for PA6, or a halogen-free flame retardant PA6 comprises, by weight, 80-100 parts of PA6, 30-60 parts of aluminum hydroxide, 5-20 parts of diethyl aluminum phosphinate composite, 30-60 parts of glass fiber, and 0.5-3% of a silane coupling agent. The PA6 flame retardant plastic of the present invention has characteristics of low cost, no halogen, environmental protection, stable color, high mechanical property, and good flame-retardant effect.

Description

technical field [0001] The invention relates to a plastic, in particular to a PA6 flame-retardant plastic. Background technique [0002] Fire is a symbol of human civilization. Its application in human life has promoted the progress of history, but at the same time, it can swallow a large amount of social wealth in an instant and endanger people's lives. According to statistics, there are more than 5 million fires every year in the world, nearly 100,000 people die in the sea of ​​fire, hundreds of millions of properties are destroyed, and countless people lose their relatives. [0003] The vast majority of plastics are flammable substances, and plastic building materials, transportation materials, household appliances materials, etc. require plastic products to be non-combustible and have good flame retardant performance, and the smoke generation of plastics in fires is required to be small . For this reason, it is very important to choose to add flame retardants in plasti...
