Plastic additives, also known as plastic additives, are compounds that must be added to improve the processing properties of polymers (synthetic resins) during molding or to improve the performance of the resin itself. For example, in order to reduce the molding temperature of the polyvinyl chloride resin, the plasticizer is added to make the product soft; and the foaming agent is added to prepare a foam having a light weight, vibration resistance, heat insulation and sound insulation; thermal decomposition of some plastics The temperature is very close to the molding temperature and cannot be formed without the addition of a heat stabilizer. Therefore, plastic additives occupy a particularly important position in plastic molding processing. There are many ways to classify plastic additives. The more common methods are to classify them according to their functions and functions. In functionally equivalent categories, it is often further subdivided according to the mechanism of action or the type of chemical structure.
With the expansion and popularization of plastics applications, the production of plastic products in China has now exceeded 20 million tons. With the increase in the processing volume of plastics and the improvement of the performance requirements of plastic products, the consumption of plastic processing aids will become more and more At the same time, the grade requirements of the products are getting higher and higher. Magnesium oxide is also used more and more widely. As one of the fillers for plastic additives, the demand is increasing year by year.
Since 2010, the amount of plastics and additives in China has reached more than 2 million tons. According to the development requirements of high efficiency, low toxicity or non-toxicity and environmental friendliness of plastic additives, the future development of plastic additives in China is as follows:
1 plasticizer, stable supply, while increasing the proportion of non-toxic, cold-resistant, heat-resistant, flame-retardant and permanent plasticizers, the development of products such as phosphoric acid, fatty acid esters and epoxy esters.
2 Antioxidants will be developed in terms of high efficiency, non-toxicity, dust-free, high molecular weight, complex multi-functionalization and specialization.
3 The heat stabilizer should conform to the mainstream of low toxicity and non-toxicity, and develop a composite type and special type rare earth heat stabilizer, which is suitable for the calcium/zinc composite heat stabilizer of PVC.
4 light stabilizers to increase production capacity, its development direction is high efficiency, high molecular weight, composite, multi-functional, non-toxic, HALS is still the mainstream of development.
5 Flame retardant should reduce the proportion of halogen products, and vigorously develop inorganic flame retardants, such as hydrogen, the second petroleum and chemical industry development (KUC) International Forum report alumina, magnesium hydroxide.
6 Emphasis on the development of multi-functional antistatic masterbatch, low toxicity and non-toxic solid (liquid) state antistatic agent.
7 Develop high-grade impact modifiers such as ACR and MBS.
The plastics processing industry has maintained rapid growth as China's economy continues to prosper and has great potential for development. The plastics industry is driven by positive factors such as the promotion of energy-saving emission reduction and circular economy development policies, economic and technological innovation, the acceleration of the development of socialist new rural construction, the continuous advancement of urbanization, and the promotion of domestic consumption. The great development has been further promoted.
