Problems solved by technology

In recent years, block silicone oils of various concepts have emerged one after another, such as five-membered and six-membered multi-component copolymerization, polyurethane polyether block silicone oil, hyperbranched silicone oil with T-shaped structure, etc., but its essential structure has not changed. Polyether, amino, organic The ternary components of the silicon core have basically not changed, so if these silicone oils are used to treat textiles, the bulkiness, smoothness and softness of the textiles will not be able to achieve a qualitative improvement

Abstract

The invention discloses high-elasticity resin modified silicone oil. The invention relates to the field of fine chemical synthesis, in particular to a high-molecular polymer, which has the main structural general formula shown as the specification, wherein A is CH2CH2O, B is a group represented as the specification, R1 is CH2CH2CH2, R is m, n, p, z, x is an integer, 3 < = x < = 5, 2 < = m < = 4, 5< = n < = 7, 105 < = p < = 145, and 2 < = z < = 4. According to the invention, a polyurethane material has a soft and hard chain segment block structure, so that the high-elasticity resin modified silicone oil is developed on the basis of the principle that the silicone oil has high elasticity and can endow a material with high elasticity, high-activity polyurea elastic resin with a soft and hardblock structure is connected on the basis of an organic silicon soft chain segment; the high-elasticity resin modified silicone oil structurally has a soft-hard chain segment, so that the high-elasticity resin modified silicone oil has a better treatment effect on fabric treatment compared with other silicone oil.

Description

technical field [0001] The invention relates to the field of fine chemical synthesis, in particular to a highly elastic resin-modified silicone oil and a preparation method thereof. Background technique [0002] In the past 10 years, the development of polyetheramine-based silicone oil has reached a highly mature stage. When it comes to the price hand-to-hand combat stage in the stock market, it is difficult to carry out alternative incremental growth through performance improvement, and it can only squeeze out the market share of competitors through price wars. ; Due to the high transparency and homogeneity of the synthesis process, core raw materials, and cost-effectiveness of block silicone oil, companies are forced to innovate the structure of silicone oil to improve performance and effect, so as to effectively replace block silicone oil and amino silicone oil for market competition. readjust. In recent years, block silicone oils of various concepts have emerged one aft...
