MQ silicone resin is a special polysiloxane, which is a relatively special polyorganosiloxane product composed of monofunctional chain links and four-functional chain links. Since there are only two basic units that make up MQ silicone resin, its molecular size is achieved by adjusting the molar ratio of M/Q. As M/Q increases, the form of the silicone resin will change from solid powder to oily liquid. . In addition, the physical properties of MQ silicone resin, including density, viscosity, transparency, softening point, hydrophilicity and lipophilicity, will all change accordingly.
Currently common MQ silicone resins can be divided into: methyl MQ silicone resin, methyl phenyl MQ silicone resin, methyl vinyl MQ silicone resin, methyl hydrogen-containing MQ silicone resin, etc. The introduction of phenyl groups will not only improve the heat resistance and refractive index of silicone resin, long-chain alkyl groups will increase the hydrophobicity of silicone resin, and the introduction of vinyl and hydrogen can prepare addition-type silicone resin. Since MQ silicone resin and ordinary silicone resin have different molecular structures, its use is different from ordinary silicone resin. Its main application is as an important component, forming a multi-phase system together with other substrates to improve the properties of the matrix. performance.
At present, the main applications of MQ silicone resin include the preparation of adhesives such as silicone pressure-sensitive adhesives for tackification and reinforcement, as well as reinforcing fillers for liquid silicone rubber. In addition, they also include heat-resistant fillers, hydrophobic agents, and surfactants. , release agent, anti-adhesive agent and used in skin care products, etc. Among them, the most widely used ones are the reinforcing filler of liquid silicone rubber and an important component of silicone pressure-sensitive adhesive.

According to the different synthetic raw materials, the production method of MQ silicone resin can be divided into sodium silicate method and orthosilicate method. Sodium silicate is a water-soluble silicate, and its aqueous solution is commonly known as water glass. It is one of the main raw materials for preparing MQ silicone resin. Using sodium silicate method as raw material to prepare MQ silicone resin has the characteristics of wide source of raw materials, low cost and simple process. The orthosilicate method has high product yield and high catalytic efficiency. The molecular weight can be easily controlled by controlling the reaction process and reaction materials. There is no contamination of the corrosive environment of the equipment by hydrochloric acid. The catalyst is also easy to separate and the waste treatment is simple. However, The resulting resin has a higher hydroxyl content.
According to the “2022-2027 MQ Silicone Resin Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center, At present, there are many domestic MQ silicone resin manufacturers, including Jiancheng Group, Wanhua Chemical, and Shenghonghui New Energy. Among them, Wanhua Chemical is expected to build a 15,000 tons/year silicone MQ resin device; Shenghonghui New Energy’s fluorosilicone high-end refinement project phase one Upon completion, there will be an MQ silicone resin production capacity of 5,000 tons/year.
Industrial analysts said that MQ silicone resin, as a mid-to-high-end silicone resin material, is mainly used together with other copolymers to optimize The role of matrix properties. With the high-end and refined development of the terminal industry, my country’s materials, especially silicone materials, are constantly optimized, and the demand for MQ silicone resin applications continues to rise. The MQ silicone resin market has huge development potential, attracting many companies to deploy. In 2022, my country’s actual production capacity of MQ silicone resin will reach more than 10,000 tons.
