As a polymer with Si-N repeating unit as the main chain, polysilazane is widely used in the fields of mechanical hardware, MEMS, automobile and aviation, energy and electric power, oil and gas chemical industry, transportation, medicine, kitchen and sanitary, construction and photoelectricity, marine ship and porous ceramics, high temperature resistant coatings, ceramic fibers, ceramic matrix composites and so on:
A high-temperature corrosion-resistant wear-resistant thermal barrier coating ---- polysilazane can be used for 300 ℃ - 1000 ℃ high-temperature corrosion-resistant surface protection coating for automotive, aviation exhaust pipe, nozzle, etc., long-term use of the working conditions resistant to flame scouring thermal shock does not crack. It can withstand high temperature above 1800℃.
Second, insulation voltage resistant three anti paint protective coating ----- polysilicon nitrogen can be used in electronic packaging and new energy battery compartments, energy storage cabinets, transformers, inverters, charging piles, etc. protective coating, dielectric strength ≥ 105V/mm, to provide insulation, voltage, weather, radiation, oxidation, and moisture, mildew, salt spray automotive, etc., "three anti-painting "coating protection.
Third, hydrophobic graffiti resistant weather resistant ring barrier coating ---- polysilazane long-term water contact angle of 90 ℃ or more, properly modified water contact angle of up to 120-130 ℃ or more, can be used for photovoltaic panels, architectural curtain walls, docks and bridges, kitchen and bathroom appliances, public facilities and other graffiti resistant, self-cleaning, abrasion-resistant, ageing-resistant and other coating protection.
Fourth, polysilazane binder ---- polysilazane Si- and substrate containing polar -OH reaction to generate Si-O bond, polysilazane NH- can react with the substrate's polar groups, at the same time, Si-NH-Si bond and the substrate surface -OH easy to react, the product is cured to form a three-dimensional crosslinked structure, giving the material good mechanical properties, which brings and substrate a good combination of strength, is used in Structural adhesives, potting adhesives and high temperature adhesives.
V. Modifying additives ---- with Si-H, Si-C=C, N-H and other active groups, in addition to modification of phenolic, epoxy, polyurethane and other resins, but also can be used for reactive, additive additives, as well as carbon fibers, glass fibers, basalt fibers, such as bonding sizing agent.
Six, polysilazane precursor ---- polysilazane as a precursor, its solid polysilazane ceramic yield is higher than 80%, continuous Si3N4 fiber use temperature up to 1600 ℃. Silicon nitride Si3N4 as a covalent compound with high bond energy, can form oxide protective film in air, not oxidized below 1200 ℃, 1200-1600 ℃ to generate a protective film can prevent further oxidation. Therefore, silicon nitride is often used to manufacture bearings, gas turbine blades, mechanical sealing rings, permanent molds and other mechanical components.
