High-performance halogen-free flame-retardant PC/ABS alloy material and preparation process thereof

Abstract

The invention discloses a high-performance halogen-free flame-retardant PC / ABS alloy material and a preparation process thereof. Raw materials for the material comprise main materials and accessory materials, wherein the main materials comprise, by weight, 70 parts of polycarbonate and 30 parts of acrylonitrile-butadiene-styrene, and the accessory materials comprise, on the basis of 100 parts of the main materials, 5 to 20 parts of a fire retardant, 0 to 5 parts of a compatilizer, 0 to 0.5 part of polytetrafluoroethylene and 0 to 0.15 part of an anti-oxidant. The alloy material prepared in the invention has a unique self-extinguishing character, good processability, compatibility and thermal stability; the addition amount of the fire retardant in the whole alloy material is obviously decreased compared with the addition amount of a fire retardant in the prior art, good flame resistance is obtained while other performances of the alloy material are not influenced, and obviously decreased addition amount of the fire retardant is beneficial for environmental protection.

Description

technical field [0001] The invention relates to the technical field of processing a halogen-free flame-retardant alloy material, in particular to a high-performance halogen-free flame-retardant PC / ABS alloy material and a preparation process thereof. Background technique [0002] PC / ABS alloy material has been popular all over the world since it was developed by Borg Warner Company of the United States in 1963. It has become one of the world's largest selling polymer alloys and is widely used in the automotive industry, household appliances, communication equipment and office equipment, etc. field. The above-mentioned application fields all have strict fire safety standards, which require materials with excellent flame retardant properties. However, due to environmental protection requirements, materials and products of halogen-containing flame-retardant systems are strictly restricted, especially in the electrical industry, because halogen-containing flame-retardant Corros...

AI Technical Summary

Problems solved by technology

The above-mentioned application fields all have strict fire safety standards, which require materials with excellent flame retardant properties. However, due to environmental protection requirements, materials and products with halogen-containing flame-retardant systems are strictly restricted, especially in the electrical industry, because halogen-containing flame-retardant Corrosive gases will be produced during pyrolysis of combustion system materials. Even if the concentration is very low, it may damage key components in electrical equipment and cause the entire set of electrical equipment to fail.

[0003] The current alloy materials mainly change the flame retardant effect by changing the raw material formula, but in the existing halogen-free flame retardant PC / ABS alloy formula, in order to make the flame retardant efficiency low, more flame retardants are added, but It will greatly reduce the mechanical properties of the halogen-free flame-retardant PC / ABS alloy, which cannot meet the production needs
