Modified plastics is a plastics industry that involves a wide range of areas, high technological content, and can create huge economic benefits. The plastic modification technology - filling, blending and reinforcement modification is deeply penetrated into the raw materials and molding processes of almost all plastic products. From the production of raw resin to the modified plastic masterbatch of various specifications and varieties, in order to reduce the cost of plastic products and improve their functionality, plastic modification technology is inseparable. Ordinary plastics often have their own characteristics and defects, and modified plastics are to change the properties of plastics. The technologies include the following
1). Reinforcement: Blend glass fiber, etc. with plastic to increase the mechanical strength of plastic.
2). Filler: Blending fillers such as minerals and plastics to change the shrinkage, hardness, strength and other properties of plastics.
3). Toughening: By adding a toughening agent to ordinary plastics to improve the toughness of plastics, the product after toughening and modification: rail gaskets.
4). Flame retardant: adding a flame retardant to ordinary plastic resin can make the plastic have flame retardant properties. The flame retardant can be a composite system of one or several flame retardants, such as bromine + antimony series, phosphorus series , nitrogen, silicon, and other inorganic flame retardant systems.
5). Cold resistance: Increase the strength and toughness of plastics at low temperatures. Generally, the inherent low temperature brittleness of plastics at low temperatures limits the application in low temperature environments. It is necessary to add some low temperature toughening agents to change the brittleness of plastics at low temperatures, such as Plastic parts such as car bumpers generally require cold resistance. Modified plastics refer to plastic products that are processed and modified on the basis of general plastics and engineering plastics by filling, blending, reinforcing and other methods to improve the properties of flame retardancy, strength, impact resistance, toughness, etc.
Modified plastics have been used in more and more downstream fields with their superior cost performance. It can be said that modified plastics have become a consumption trend, and the following four factors are implied behind this trend:
1. High performance: Modified plastics not only have the advantages of traditional plastics, such as low density and corrosion resistance, but also have good physical and mechanical properties, such as high strength, high toughness, high impact resistance, wear resistance and shock resistance. In addition, the improvement of the comprehensive properties of plastics provides a basis for its wide application in downstream fields.
2. Low cost: Compared with other materials, plastics benefit from the advantages of high production efficiency and low density, and have lower costs. The cost of plastic per unit volume is only about one-tenth of that of metal.
3. Consumption upgrade: With the improvement of living standards, people have begun to pursue more excellent product performance, requiring home appliances and other products to be more beautiful, safe and durable, thus putting forward higher requirements for the upstream plastics industry, requiring them to have better performance. Processability, mechanical properties, durability and safety.
4. Technical factors: More than 1,000 polymers have been discovered in the world, but only dozens of them have real application value. The development of new polymers is not only a huge investment, but also has unclear application prospects. On the contrary, modification technology can not only improve the current It has the properties of polymers to meet the needs of the industry, and at the same time can reduce the cost of some high-priced engineering plastics, becoming an effective way to develop the plastics industry.
