High heat conduction silicon grease production process

Abstract

The invention discloses a high heat conduction silicon grease production process which comprises the following steps: A1, preparing raw materials, namely preparing four stainless steel round buckets of 1000L, nano modified heat conduction packing (including 15% of an oxide, 10% of nitride, 30% of nano heat conduction powder, 5% of copper powder, 15% of zinc powder, 15% of magnesium powder and 10%of silicon carbide, boron nitride, aluminum oxide, silicon oil (including 45% of dimeticone and 55% of benzyl modified silicon oil), and aids (including 20% of sodium hexametaphosphate, 60% of sodiumphosphate and 20% of sodium tripolyphosphate), and respectively sealing and preserving the nano modified heat conduction packing, the boron nitride, the aluminum oxide, the silicon oil and the aids inthe four stainless steel round buckets at a normal temperature. By adopting the process, the dispersion effect of raw materials is effectively improved, the conversion rate of the raw materials is effectively increased, particularly as the raw materials are subjected to preheating treatment, the activity of raw material molecules is greatly improved, the conversion rate is increased, in addition,the dispersion times of the raw materials in different environments are respectively prolonged, the dispersion effects of the raw materials are further improved, and the conversion rate of the raw materials is further increased.

Description

technical field [0001] The invention relates to the technical field of high thermal conductivity silicone grease, in particular to a production process flow of high thermal conductivity silicone grease. Background technique [0002] Thermally conductive silicone grease is a kind of high thermal conductivity insulating silicone material, which almost never solidifies, and can maintain the grease state during use for a long time at a temperature of -50°C-+230°C. Widely used in the contact surface between heating elements (power tubes, silicon controlled rectifiers, electric heating stacks, etc.) Ensure the stability of the electrical performance of electronic instruments, meters, etc.! For example, power amplifiers, transistors, tubes, CPUs and other electronic components. [0003] Ordinary thermal conductive silicone grease is made of metal oxides such as aluminum oxide as thermal conductive filler, and its thermal conductivity is only 0.3-0.8 W / (m K). The performance is s...
