Reclaimed ABS (acrylonitrile butadiene styrene) environment-friendly modified material and preparation method thereof

Abstract

The invention relates to the technical field of recycling of ABS reclaimed materials, in particular to a reclaimed ABS (acrylonitrile butadiene styrene) environment-friendly modified material and a preparation method thereof. The material comprises ABS reclaimed materials, flame retardant, flame-retardant synergist, compound antiager, antioxygen, flexibilizer and coupling agent. Environment-friendly modified graphene is adopted as the flame retardant, so that flame retardation of the material is improved, and the material is environmentally friendly; waste nitrile rubber is adopted as the flexibilizer, so that mechanical property of the material is improved, waste turns into wealth, and the requirement on environmental protection is met; being added with the compound antiager, the material is high in ageing resistance. The reclaimed ABS material is equivalent to a new flame-retardant material in flame retardance and mechanical properties, the reclaimed ABS material prepared by the method is excellent in performance, the preparation technique is simple and easy to operate, production cost is low, economic benefit is high, and industrialization is easy to realize.

Description

technical field [0001] The invention relates to the technical field of recycling ABS recycled materials, in particular to a recycled ABS environmentally friendly modified material and a preparation method thereof. Background technique [0002] Today, China has entered the peak period of discarding household appliances, and more than 30 million discarded household appliances will be produced every year. Such a huge waste of household appliances will inevitably produce a large amount of waste plastics. There are three ways to recycle waste plastics: sanitary landfill, incineration for heat, and resource recycling. Among them, landfill and incineration are likely to cause waste of resources and secondary pollution, which is contrary to the theme of the era of green environmental protection. [0003] Nowadays, the recycling of waste plastics mainly adopts the method of recycling, mainly including direct regeneration, modified regeneration, gasification and oil treatment. Howeve...

Problems solved by technology

However, for recycled ABS materials, its mechanical properties are much lower than those of fresh ABS raw materials. If you want to continue to use ABS recycled materials in electronics, electrical appliances, automobiles and other industries after modification, you must improve their flame retardancy, toughness, etc. Effective modification of impact resistance and impact resistance to meet material performance requirements for different uses

[0005] However, most of the flame retardants currently used are bromine and red phosphorus flame retardants. Although they have a more obvious effect on the regeneration and modification of ABS, they have certain damage to the environment. People are looking for a more environmentally friendly ABS modification. method
