 Dec 22, 2022|View:461

With the development of society, automobiles are becoming more and more common. The current flame-retardant polymer materials used in automotive parts are mainly ABS Plastic Boards which are environmentally friendly, highly efficient, and have excellent mechanical processing properties and mechanical properties.

ABS Plastic Board

1. The combustion mechanism and flame retardant mechanism of ABS Plastic Board.

(1). Combustion mechanism.

Temperature, combustible material, and oxygen are the three elements of fire.

After the temperature rises to a certain value, ABS Plastic Board decomposes into high molecular compounds through heat and then continues to decompose into low molecular compounds. These low-molecular-weight compounds are volatile combustible substances that accumulate to a certain concentration in the air and then burn. The release of combustion heat further promotes the decomposition of the ABS Plastic Board. The combustion of ABS Plastic Board is divided into two processes: the decomposition of thermal oxygen and combustion.

(2) Flame retardant mechanism.

The ABS Plastic Board combustion mechanism shows that flame retardation can be achieved by mitigating or preventing one or more factors. The flame retardant mechanism of polymer materials is generally divided into three categories: gas phase flame retardant, condensed phase flame retardant, and heat exchange interrupted flame retardant.

2. ABS Plastic Board is used in automotive parts.

ABS Plastic Board is the most used polymer material for home appliances worldwide. About 80% of ABS Plastic Board consumption in China is used to produce home appliances. ABS Plastic Board is a typical material suitable for automotive painting because of its strong durability of plastic surface coating and corrosion resistance. It is also used in the production of automotive parts. ABS resin contains only c, h, o three elements and has flame retardancy, so it has poor stability. The ignition process also generates odorous gases and black smoke particles, and there are safety hazards in using it directly for vehicle parts. Therefore, before use must be modified for flame retardancy and heat resistance treatment.

Halogen flame retardant's efficiency is high, of which the bromine flame retardant effect is better than the chlorine system environmental pressure. Still, bromine flame retardants rely on the two main advantages of exceptionally special flame retardant effect and cheap cost. Relative to some of the strict flame retardant standards in the field and flame retardant materials, bromine flame retardants are most prominent in about 70% of electronic products for bromine flame retardants, of which decabromodiphenyl ethane is mainly used for flame retardant ABS. However, with the popularity of environmentally friendly halogen-free, halogen-free, phosphoric acid nitrogen class flame retardants for ABS Plastic Board is also attracting attention.

Melt mixing ABS and polycarbonate ( PC ) to get PC/ABS composite material has the advantages of both ABS and PC, high heat deflection temperature and stability, and improved processing performance. PC/ABS alloy, currently the most produced and fastest-growing resin alloy, can be used in automotive instrument panels, battery packs, car bodies, and other parts. PC resin is a flame retardant self-extinguishing material that UL94 is V2 level. Still, the flame retardancy decreases when mixed with ABS, so it needs to be modified for flame retardancy before being used in automotive parts. Currently, PC / ABS alloy flame retardant modifications commonly used in flame retardants are halogen flame retardants, phosphorus flame retardants, nano flame retardants, and so on.

3. The research focus is the future development of flame-retardant ABS Plastic boards for automotive parts.

(1) Theoretical research on flame retardant ABS Plastic Board for automotive parts.

Researchers should apply the methods, mechanisms, and standards of ABS Plastic Board flame retardant research to study the flame retardant properties of automotive polymer materials according to the characteristics of automotive parts applications and explore how to improve the flame retardant properties of ABS Plastic Board for automotive parts.

(2) Development of flame retardants for high-performance ABS Plastic Boards.

The focus of research on high-performance flame retardants will shift to developing compounding efficiency flame retardant technology, halogen-free flame retardant, intumescent flame retardant, ultra-fine, nano-technology, efficient surface chemical modification technology, and multi-functional technology.

(3) Modification and optimization of ABS Plastic Board for auto parts.

At present, the world of modified plastics still has a high technical threshold not only the strength, hardness, toughness, and other basic requirements continue to improve, in the electrical properties, health and safety performance, as well as environmentally friendly performance and other aspects also continue to put forward new requirements, automotive parts with ABS Plastic Board also in the performance of high-end, functional, high-performance flame retardants alone is not enough, to improve the overall performance of automotive parts with flame retardant polymers, the need to Improve each special performance.
