First, the concept and development of modified plastics
Concept: Plastic polymers can be made into plastics that meet certain requirements by adding functional additives, additives, fillers, etc., or by blending different polymers, by physical means, chemical methods or by combining different methods. Things.
Modification technology: mainly adopts blending, filling, toughening, strengthening, compatibility, flame retardant, alloying and other technologies to improve the flame retardancy, aging resistance, mechanical properties and electrical, magnetic, optical and thermal properties of the resin. Characteristics.
On the basis of general plastics engineering and high-performance engineering plastics, the production process of modified plastics also introduces cutting-edge sciences such as nanotechnology, condensed matter physics, energy conservation and environmental protection, which further increases the breadth and depth of application of plastic products and saves oil. The advantages of resources, reducing production costs and increasing economic benefits include the traditional industries such as office equipment, household appliances, electrical and electronic, and high-tech fields such as rail transit, precision instruments, aerospace and new energy.
From the comparison of traditional industry and high-tech demand, the demand of traditional application areas pays more attention to the cost of products and the consistency between different batches, while the high-tech field pays attention to whether the performance of products meets the design needs. At present, there are hundreds of companies engaged in modified plastics, and there are tens of thousands of employees. The development of markets such as automobiles, household appliances, and lighting has led to an increase in the consumption of modified plastics, with an average annual growth rate of over 15%.
Second, the main output industry of modified plastics
1. Environmentally friendly passenger transport leading modified plastics for vehicles
In a car, there are multiple parts that require modified plastics, such as bumpers, fuel tanks, steering wheels, interiors, and more. The weight of modified plastic used in each car is about 7% to 10% of the car's own weight, between 40 kg and 90 kg. In the United States, Germany, Japan and other developed countries, the proportion of automotive modified plastics is between 10% and 15%, and some even as high as 20%.
Suffice to see, modified plastics have a huge market in the automotive industry.
In the lightweight technology, the carbon fiber reinforced thermoplastic composite (CFRTP) prepared by combining carbon fiber as a reinforcement and engineering plastics with corrosion resistance, low specific gravity, impact resistance, easy molding, and secondary use has been excellent in performance. Widely used in the automotive field, it can replace traditional metal materials and glass fiber reinforced materials, such as automotive front-end modules, engine peripherals, body, seat frame, battery bracket, power battery package and so on.
In addition to lightweight materials, environmentally friendly materials such as spray-free and low odor have also become popular in the automotive field. The coating contains a large amount of VOC (Volatile Organic Compound). The spray-free material is an environmentally friendly material that can replace the traditional coating. It is a popular automotive material and can be applied to automotive control panels and grids. Parts such as grids, fenders, bumpers, and mirror housings can also be metallic.
2. Demand for modified plastics by rail transit
The development of China's rail transit is just like the speed of China's high-speed rail. The localization rate of high-speed rail and motor train is getting higher and higher, and the ride comfort is improved, which undoubtedly puts higher performance requirements on domestic materials.
In the field of modified plastics, polyamide composites have the characteristics of high elasticity, self-lubricity, wear resistance, impact resistance, corrosion resistance, etc., which can meet the performance requirements of bearings, and play a role in railway transportation safety, high speed and heavy load. Key role.
3. The proportion of domestic aviation materials is gradually increasing
Our aviation sector has been subject to people and relies heavily on imported materials. For a long time, domestic material suppliers have been able to produce materials that meet aviation performance requirements.
However, with the maturity of R&D technology of domestic aircraft such as C919, Yun 20 and 殲20, a series of new materials research and development have been launched simultaneously in China, more and more technical barriers have been broken, and more and more domestic high-performance materials have begun. Applied to the aviation sector.
