Anti-static silicone material

The formula of antistatic silica gel, the main ingredients are as follows: silicone rubber, vinyl silicone rubber, stearic acid, fluorosilicone rubber, vulcanizing agent, reinforcing fillers, weak reinforcing fillers, additives, colorants. The reinforcing fillers used are acetylene carbon black, conductive furnace black, and conductive groove black materials, which have good electrical conductivity and good antistatic properties. The weakly reinforcing fillers used are diatomite, titanium dioxide, and quartz powder. The mixture is used as an antistatic filler. The raw materials are all derived from minerals, and the price is low, the application range is wide, and the production cost is low. The vinyl silicone rubber is used as the main raw material to improve the tensile strength and tear strength of the prepared silicone rubber. The additive is a mixed liquid of polyvinyl alcohol coating liquid and hardening liquid, which can significantly improve the abrasion resistance of the product, improve the service life of the product, and is suitable for a wide range of applications.
The preparation method of antistatic silica gel sheet belongs to the field of antistatic composite materials, which involves the treatment of a silicone gel with a conductive agent, compounding it with a modified thermally conductive powder filler, and thermal curing under certain conditions to prepare an antistatic type for use in electronic circuits. Sheet, thermal power element, flexible sheet with thermal interface gap. The antistatic silica gel material consists of a silicone gel matrix treated with a conductive agent, and a variety of different types of different particle sizes and thermally conductive inorganic filler powders treated with a coupling agent. The flexible material can be passed through a multi-roll calender. The rolling thermal curing is mass-produced. The surface resistance of the material that can be prepared by this method can be adjusted within the range of 5 to 9 ohms of 10, and the stripping electrostatic voltage is <1KV.


Antistatic heat-resistant silica gel strip and manufacturing process thereof. The antistatic heat-resistant silica gel includes a base material layer and an antistatic heat-resistant silica gel layer coated on the upper surface of the base material layer; the base material layer is a PI film and an antistatic heat-resistant silica gel layer. Including the following parts by weight of raw materials: silica gel, color gel, vulcanizing agent. This anti-static heat-resistant silicone skin conducts heat faster and more uniformly, and the material is anti-static, so there will be no defects of static electricity and electrostatic breakdown; the number of laminations is 60 # 80 times, which reduces the loading and unloading and increases the capacity; no The precipitation of silicone oil will not affect the edge sealing of UV glue.
