2. Core technology

Chen Chun, chairman of Liaoning Fuqing Auxiliary Co., Ltd., has been engaged in the research and development and fine production of organic peroxides since 1996. Through years of unremitting efforts and efforts, he has experienced many failed trial production. Through independent research and development of production equipment and process flow, the purity of cumene hydroperoxide has been increased from 80-85% of the regular to more than 95%. Its core technology is: the production device of high-purity cumene hydroperoxide is completely completed by the research and development team led by Chen Chun after years of practice and trial production. This set of device and process has now applied for one invention patent and four utility model patents (application number: 2017102607417); Two utility model patents to be approved (application number: 2017209778915\2017209712903); the two technologies have obtained utility model patent certificates on November 28, 2017 (patent number: ZL 201720417731.5\ZL201720418084X). The set of production equipment and process has a number of innovative points, the production cycle is short, the new equipment production cycle than the original equipment production cycle shortened by 2/3. The product output rate is high, and the one-time pass rate reaches 100%. With the advantages of safety and environmental protection, the entire production process to achieve zero emissions without pollution. The original process stipulates that one-time oxidation shall not exceed 25%. Now, the process equipment independently developed by the enterprise can increase the one-time oxidation to about 35%, and the qualified product of cumene hydroperoxide, which can reach 80% content only after three times of distillation in the original process, can be changed into a product with a high content of 95% after one time of distillation. After the mass production of Fushun Qingyuan Auxiliary Factory in the past three years, the production technology and performance indicators of the products are at the international level, and the production process and customers are very stable. Therefore, the production of high-purity cumene hydroperoxide will be increased in Fushun Qingyuan Auxiliary to meet the market demand. BIPB is one of the important products in the crosslinking agent, which is the substitute of DCP. DCP has been widely used in various industries since the 1960 s, but the decomposition of DCP products after vulcanization will produce some toxic substances, leaving a pungent odor to downstream products, and causing harm to human body and environment. In order to find a more environmentally friendly and health-friendly alternative to DCP, practitioners in various countries have made a lot of attempts and developed an ideal alternative product-BIPB. Compared with DCP, BIPB has the advantages of non-toxic and tasteless, so it is called "tasteless" DCP. Especially suitable for indoor rubber and plastic products. And widely used in medical equipment, food packaging, children's toys and other fields. Under the same crosslinking conditions, the addition amount of BIPB is only 2/3 of DCP, which further reduces energy consumption and pollution emissions." Most of the BIPB produced at home and abroad are para-and meta-mixtures, and their crosslinking effect is far less good than that of pure products. Because the two boiling point difference is small. Distillation separation method, energy consumption, and it is difficult to achieve high purity. Our company uses low-temperature separation technology (patented technology) to separate it. The advantage is that the product has high purity, simple operation and low energy consumption. Take the separation of a ton of product as an example. Distillation requires 1.615 million kilocalories of heat and 227 kilograms of coal. 590.2kg of carbon dioxide emissions; 1.9kg of sulfur dioxide; 1.7kg of nitrogen oxides. The low-temperature separation technology requires 30 degrees of electricity, equivalent to 3.7 kilograms of coal. No pollutant emission. This project adopts the condensation reaction synthesis method, directly uses two-one (2-hydroxyisopropyl) benzene as raw material and acid as catalyst. This production route has the characteristics of low consumption of raw materials and high reaction yield, mature and reliable process, no direct atmospheric emissions, adopts equipment to improve safe production conditions, and has strict safety production system and procedures to ensure production safety. For the double 2,5 product, the two-step reaction synthesis route of dimethyl hexanediol, hydrogen peroxide and tert-butyl alcohol is used, which has the characteristics of less side reactions, low control requirements and high reaction yield.

 

3. Product Application

The peroxide products produced in this project are di (tert-butyl isopropyl peroxide) benzene, 2,5-dimethyl-2,5-di (tert-butyl peroxy) hexane, cumene hydroperoxide, dicumyl hydroperoxide, dicumyl peroxide and tert-butyl cumene hydroperoxide, which are widely used in various fields of production and life as polymerization initiators, crosslinking agents, vulcanizing agents, curing agents, catalysts and so on.

The free radicals produced by the thermal decomposition of di (tert-butyl-isopropyl peroxide) benzene (BIPB) peroxide have high stability and can be used as polyethylene, EPDM rubber, ethylene-vinyl acetate copolymer, silicone rubber, nitrile rubber and other rubbers and plastics crosslinking agent. BIPB peroxide has high crosslinking efficiency, and the products have good heat resistance, low temperature flexibility and pressure deformation.

2,5-dimethyl-2,5-di (tert-butylperoxy) hexane can be used as a vulcanizing agent for polyurethane rubber. Compared with other rubbers, polyurethane rubber has excellent comprehensive properties such as high mechanical properties, excellent wear resistance, good oil resistance and aging resistance. It is mainly used in some products with high performance requirements, such as wear-resistant products, high-strength oil-resistant products and high-modulus products. Peroxide curing process is a relatively new process, which is beneficial to improve the compression deformation and aging resistance of materials. Compared with sulfur vulcanization, the peroxide product di (tert-butyl peroxide isopropyl) benzene and 2,5-dimethyl-2,5-di (tert-butyl peroxy) hexane vulcanized and mixed polyurethane rubber produced by this project has the characteristics of short vulcanization time, fast vulcanization speed, high torque, high oil resistance and high low temperature resistance, and does not use sulfur, which is more environmentally friendly. With the enhancement of people's awareness of environmental protection and the improvement of their quality of life, users will have more and more demand for several products of this project.

 

4, Product Market Analysis

At present, the average selling price of several products in this project is 29000 yuan/ton.
