The nature and use of ABS plastics in the field of raw materials for chemical production

Abstract

This paper introduces in detail the nature and use of ABS plastics in the field of raw materials for chemical production. Through the elaboration of the composition, properties, production process and application fields of ABS plastics, the important position and role of ABS plastics in the production of chemical products were demonstrated.

1. Introduction

With the continuous development of science and technology, plastics have become an indispensable material in people's daily life and industrial production. Among them, ABS plastic has become an important member in the field of chemical production raw materials because of its excellent performance and wide application. This article will delve into the properties and uses of ABS plastics.

2. ABS plastic properties

ABS plastic is a terpolymer of acrylonitrile, butadiene and styrene, with the following properties:

1. Thermal stability: ABS plastic has high thermal stability, Can maintain its mechanical properties and dimensional stability within a certain temperature range.
2. Impact resistance: ABS plastic has good impact resistance, even at low temperatures is not easy to embrittlement, so it is widely used in the manufacture of large force parts.
3. processability: ABS plastic has good processability and can be processed into products of various shapes and sizes by injection molding, extrusion, blow molding and other methods.

3. ABS plastic production process

ABS plastic production process mainly includes emulsion grafting method, continuous bulk method and suspension method. Among them, the emulsion grafting method is currently the most commonly used production process, the main steps include:

1. preparation of polystyrene emulsion;
2. adding acrylonitrile and butadiene monomer in polystyrene emulsion, graft copolymerization reaction;
3. adding initiator and emulsifier, control the reaction speed and particle size;
4. post-treatment and drying, ABS resin.

4. the use of ABS plastic

ABS plastic because of its excellent properties, in the field of chemical production of raw materials has a wide range of applications, mainly including the following aspects:

1. household appliances: ABS plastic is widely used in the manufacture of household appliances products shell and parts, such as televisions, refrigerators, washing machines and so on. Due to its excellent impact resistance and processability, it makes home appliances more beautiful and durable.
2. Automotive industry: ABS plastics can be used to manufacture automotive interior parts, exterior parts and structural parts, such as dashboards, door panels, seats, etc. It can not only reduce the weight of the car body, but also improve the safety and comfort of the car.
3. Building materials: ABS plastic can be used to manufacture accessories and decorative parts of building materials, such as pipes, plates, profiles, etc. It has excellent weather resistance and processability, which can improve the service life and aesthetics of the building.
4. 3D printing material: ABS plastic is one of the commonly used materials for 3D printing. It has the characteristics of high strength, high temperature resistance, and easy processing. It is suitable for manufacturing various complex models and structures.

5. conclusion

ABS plastics in the chemical production of raw materials in the field of nature and use is very wide, for the promotion of industrial production and development plays an important role. In the future, with the continuous progress of science and technology and the expansion of application fields, the application prospects of ABS plastics will be broader.
