Ultra-high boiling point electronic fluorinated solvent is a substance with extremely high chemical activity. Due to its high activity, large molecular weight, and large number of hydrophilic groups and polar genes, it is very easy to form complexes with various metal ions and react; at the same time, the compound has certain hygroscopicity and corrosive properties.

　　Electronic fluorides with ultra-low boiling points can quickly decompose into gases or vapors at high temperatures, so their applications are limited: on the one hand, their volatile nature limits their wide application in the industry; on the other hand, they are solubility at normal temperature and pressure is small, so the scope of use is limited to a certain extent. With the development of technology and the increasing requirements for environmental protection, higher requirements are put forward for the properties and uses of such substances. For this reason, some new high-temperature structural fluorides—thermally stable fluorides and their modified products have been developed.

　　1. High-strength high-temperature-resistant electronic fluorinated solvent

　　Most of the electronic fluorinated solvents and fluoropolymers currently on the market are of medium and low strength, such as F4, CF3, C2H5ClO4, and so on. The heat-resistant temperature of this type of electronic fluorinated solvent is generally around 200-250°C, and they are generally only suitable for low-temperature conditions. When the temperature in the environment is higher than 150°C, a slow oxidative degradation process will begin, thus Affecting the quality and service life of the product.

　　There are three main methods of preparing high-intensity electron fluorinated solvent:

　　1. Using silicone resin as a raw material;

　　2. Use melamine as a raw material;

　　3. It is synthesized and processed with tetrahydrofuran as raw material. The heat resistance of these materials has reached above 400-500 ° C, and they all have good hydrolysis resistance.

　　2. High-efficiency flame retardant additives

　　To meet the needs of market development, many chemical companies have produced various new functional additives, among which flame retardant additives are one of the important varieties.

　　The role of flame retardants is mainly to inhibit the generation of free radicals generated during the combustion process and prevent the spread of flames to other parts and cause fire accidents. It can be said to be used as a fire extinguishing agent products; in addition, it can also reduce flammable The concentration of flammable gas adsorbed on the surface of the object greatly reduces or even eliminates the explosion risk of flammable gas, to achieve the purpose of fire and explosion protection.
