The plastics industry has experienced nearly 30 years of history from mixing the filler to the present use of plastic filled masterbatch. The use of mineral filler in plastics also experienced from less to more, from the development process.
The development of rubber industry in China, plastic industry started in the plastics industry, engaged in technical staff from the early chemical industry, first introduced to the use of a large number of plastic processing industry packing is widely used in rubber industry, familiar with technical personnel. Industrial production has been formed in China, by limestone chemical processing and manufacturing of light calcium carbonate, which precipitated calcium carbonate, and the usage is the largest PVC artificial leather, PVC pipe, etc. the second is the sole. With the advent of polyolefin plastics in China, plastic products with polyethylene and polypropylene as raw materials are increasing. Light calcium carbonate is one of the raw materials that must be used in calcium plastic tiles. The mass fraction of light calcium carbonate is 45%. According to the requirements of plastic products, the light calcium carbonate is used as one of the main raw materials, and the first stage of China's plastics industry is using mineral filler.
The second stage is from the end of the 70s and the beginning of 80s. Heavy calcium carbonate as the main raw materials of APP filling masterbatch research success and CALP from Japan to TSP and talcum powder as filler modified polypropylene production technology was introduced into the rise of Chinese as the representative of the plastic material in Chinese, marking the Chinese plastics industry to deepen the cognition about the use of direct mineral fillers and the awakening.
The third stage is characterized Chinese technical personnel not only began to reduce the cost of plastic raw materials and a large number of used mineral filler, modified or given plastic materials and its products with new functions of some properties of various characteristics but also focus on the use of mineral fillers for plastics, with filling, enhancement and blending means of plastics technology developed since 80s to become the China plastics industry rapid development, one of the most active fields.
The earliest purpose or the most direct purpose of mineral filler is to reduce the cost of raw materials for plastic products, and the price of plastic products is the main component of all the prices of plastic products. It is currently occupied in China
60%~70%, the proportion of certain kinds of plastic products, such as polytetrafluoroethylene, is higher. The two words of "filling" have the meaning of adulteration, but this adulteration should be based on not damaging the use of plastic flip goods, and it can also do this.
With non metallic minerals and plastic processing of both scientific and technological personnel efforts, to fill the role understanding gradually deepened, people realize that the use of filler can not only achieve the purpose of reducing the cost, and also can improve the performance of certain aspects of plastic products, if you can consciously choose the types, specifications and mineral filler to the proper use of that can make the performance of plastic materials and products in accordance with the people expected to improve; sometimes in order to make the plastic materials and products to meet the requirements of the use of certain special occasions, would rather reduce the cost in the secondary position, and sometimes, the use of functional fillers or will be a feature of developed filler in order to give plastic products, turn new function is to modification methods which can not be achieved with other plastics.
According to international statistical experience, the total amount of all kinds of fillers should be about 10% of the plastic output. The total output of plastic products in China is about 6 million 500 thousand T, and the amount of mineral filler should be 650 thousand T per year. The use of plastic products are mainly polyethylene plastic packing box, corrugated polyethylene plastic ceiling, polyethylene foam sheet, sole, polypropylene woven bags, cloth, polypropylene packing belt, PVC leather, PVC sole, PVC pipe, plate, anisotropic material, wallpaper, floor leather, floor block. The main filler used is heavy calcium carbonate, light calcium carbonate, talcum powder, kaolin, wollastonite and so on. Other functional fillers, such as magnesium, aluminum hydroxide, mica, and magnetic powder, have also been used.
