Heat-resistant polymer refers to polymer materials with good high-temperature stability, widely used in aerospace, energy, electronics, building materials and other fields. In the field of modern industry and science and technology, polymer material is an indispensable material. With the development of science and technology, people have higher and higher requirements for polymer materials, and high temperature stability is one of the important properties that polymer materials must have.
Heat-resistant polymer materials have good performance in high temperature environment, such as high temperature strength, high heat resistance, high oxidation stability, low creep and better processing performance. Therefore, heat-resistant polymer materials are the mainstream materials to meet the needs of future high-temperature applications.
1, polysilazane
Polysilazane polymer is a class of molecules containing repeats in the main chain to Si-N inorganic polymer materials, due to the special nature of its chemical structure, can be transformed into silica ceramics under high temperature conditions. Therefore, polysilazane has important application value in high temperature resistance.
Polysilazane resin silicon nitrogen bond angle is small, the molecular bond tension, so the molecular chain is not easy to ring, in the molecular polymerization reaction process is not easy to bite back, rearrangement and other side reactions, good thermal stability, by changing the substituents of silicon or nitrogen atoms can be designed to have a specific performance of the poly-silazane resins, high-temperature resistance (1800 ° C) is excellent, film hardness is high, ultra-thin varnish, low-viscosity; the majority of the type of Excellent adhesion to most types of substrates.
