2020 is an unusual year. Due to the novel coronavirus pneumonia, the market demand of isopropanol as the main raw material of disinfectants has been increasing. The situation of supply shortage has already been formed, which has led to the shortage of capacity of the major raw material suppliers and the depletion of stock. The price has increased to 15000 yuan / ton from the 7000 yuan / ton of the year.
At present, most of the terpolymer block silicone oil on the market is prepared by the reaction of epoxy silicone oil at the end of age route with polyether amines of ED series, adding 30% - 40% isopropanol. The mass ratio of isopropanol is about 40% - 50% (relative to the mass of block silicone oil). In this way, the cost per ton of block silicone oil is increased by at least 3000-4000 yuan / ton, which makes the textile printing and dyeing enterprises seriously affected by the epidemic even worse.
In order to reduce the amount of isopropanol in the process of synthesizing block silicone oil, improve the safety and cost performance of the products, and get a chance to survive in the current severe situation, the relevant enterprises in the upstream and downstream of printing and dyeing auxiliaries are stepping up their investment in technology research and development.
Hangzhou qiongtian New Material Technology Co., Ltd. focuses on the research and development of special raw materials for organosilicon finishing textile auxiliaries. Now it is launched a new generation of solventless epoxy polyether silicone oil (4000-20000 molecular weight). This product is highly reactive and does not need to add isopropanol to participate in the reaction, or can choose a small number of butyl ether solvents with low market price to synthesize with organic amine raw materials The preparation of block silicone oil, hand feel style and physical and chemical properties can basically replace the ordinary block silicone oil, which can reduce the negative impact of the cost surge of auxiliary enterprises.
