What is silicone MQ resin?
Silicone MQ resin is a kind of silicone resin with a unique structure. It is a three-dimensional spherical silicone grease formed by the co-hydrolysis polycondensation of silicone compounds containing four functional siloxane links (SiO4 /2，Q) and silicone compounds containing single functional siloxane links (R3SiO1/2，M). The molar mass of silicone MQ resin is generally 1000 ~ 8000g / mol, the glass transition temperature (Tg) ranges widely, and the state distribution ranges from viscous fluid to solid powder.
It is generally believed that silicone MQ resin is a compact spherical body with a double-layer structure, in which the spherical core is cage SiO2 with Si-O chain connection, high density and polymerization degree of 15 ~ 50, and the spherical shell is R3SiO1/2 layer with low density.
Different Types of silicone MQ resin
Due to the different organic groups r on the spherical shell, silicone MQ resin has many different types:
When R is all methyl, it is called methyl silicone MQ resin or silicone MQ resin for short; When part R is H, it is called methyl hydrogen-containing silicone MQ resin; There are also methyl phenyl silicone MQ resin, vinyl silicone MQ resin, phenyl MQ silicone resin, fluorine-containing MQ silicone resin, MDQ, MTQ silicone resin, etc.
The properties and application range of silicone MQ resin mainly depend on its synthesis process conditions and the type and number of organic groups in the molecule, that is, the number ratio of m-links to Q-Links; Among them, the organic group R mainly increases the compatibility with other components and plays a role in increasing viscosity, and the SiO4/2 chain-link mainly improves the strength of the composite and plays a reinforcing role.
