Practice has proved that the new product COPO resin developed by Xi'an University of Science and Technology has excellent market prospects and good social and environmental benefits.
COPO resin (coal-based polymer interpenetrating network alloy technology) refers to a multi-component polymer consisting of coal-polymer-other components, and a novel polymer material with good comprehensive performance obtained through alloying technology. Different grades of products or products with special functions can be obtained by controlling the preparation process. COPO resin series products can be widely used in the application fields of general plastics, engineering plastics and organic polymer matrix composites, such as chemicals, agriculture, household products, automobile industry materials, etc., and are new varieties of new general-purpose and new engineering plastic raw materials. .
For agricultural use
At present, foreign countries have developed a large number of colored plastic film, colored plastic film accounts for 1/3 of the total amount of agricultural film. In the colored plastic film, black plastic film accounts for about 90%. Therefore, it is speculated that the post-black mulch has great potential for development in China. Due to the photobiodegradability of the COPO resin (degradation products are used as high-efficiency compound fertilizers to assist the growth of crops), the preliminary estimate is that only the COPO resin for the coloring film needs The amount of 10-20 million tons / year or more. The rapid development of black agricultural mulch is due to its many advantages. For example, it can increase the temperature and heat preservation, prevent the hardening of the land, compaction, etc. Its greatest feature is to prevent agricultural debris caused by soil pollution caused by debris formed after the aging of the plastic film. The dissolution of humic acid in the membrane by the water-vapor cycle is beneficial to the growth of crops as a nutrient component and is beneficial to the elimination of white pollution. In 2002, the Xinjiang Production and Construction Corps Academy of Agricultural Sciences and the 134th Agricultural Eighth Division conducted a trial of 80 acres of cotton and received good results.
For engineering plastics
Currently PVC construction, irrigation pipes, EDPE oil and gas pipes, gas pipes, mining pipes, irrigation pipes, drinking water pipes, etc. are developing very rapidly, and the development prospects of black plastic pipes for irrigation are very bright. COPO resin-based pipes, because they can not only be recycled (secondary processing, or fuel utilization, etc.), but also can control the photolysis and have good coordination with the environment. Therefore, for the forecast of pipe for agricultural irrigation only, the annual COPO resin demand is in the range of 5-10 million tons.
