Problems solved by technology

[0004] The frequency of electric tools in the early stage was generally low, generally 4400-4700Hz. The current frequency has increased to above 5200Hz, and the working time is longer than before. In the past, it was generally 30 seconds on / 30 seconds off or 40 seconds on / 20 seconds off. The current requirement is 4 separation / 1 minute stop, therefore, the existing electric tool grease can no longer meet the high-frequency use requirements
[0005] The applicant's prior applications CN101597539A and CN102604726A, the disclosed grease can only be used in low frequency and short working time occasions, and it cannot be applied to high frequency (above 5200Hz) occasions

Embodiment 1

[0037] With 837.8g high phenyl silicone oil (phenyl content 30%) (V 25℃ , 289mm 2 / s), 27.4g diphenylsilanediol is added to the reaction kettle, after heating until it is completely melted, the specific surface area is 380m 2 / g fumed silica 82.2g, keep for 20min, cool down to 80-100℃, add T53130g, Afton diesel engine oil compounding agent HiTEC8799B50g, mix and stir for 20min, set the gap to 5μm colloid grinding once, and then use the gap setting It is determined that the front 10μ / back 2μ three-roll mill grinds 1 time.

Embodiment 2

[0039] With 796.3g high phenyl silicone oil (phenyl content 40%) (V 25℃ , 321mm 2 / s), 27.4g diphenylsilanediol is added to the reaction kettle, and after heating to be completely melted, the specific surface area is 308m 2 / g fumed silica 96.5g, hold for 30min, cool down to 80-100℃, add T53142g, Afton diesel engine oil complex agent HiTEC8799B65.2g, mix and stir for 30min, set the gap to 5μm colloid grinding once, and then use The gap is set at the front 10μ / back 2μ with a three-roll grinder for one pass.

Embodiment 3

[0041] With 410g high phenyl silicone oil (phenyl content 30%) (V 25℃ , 289mm 2 / s), 96.5g lithium bentonite, and 30g ethanol aqueous solution (95%) of polar dispersant, heat and stir to volatilize the dispersant, continue heating to 135°C, and keep the temperature for 30 minutes, add the remaining 410g high phenyl Silicone oil is used to adjust the consistency of grease, the temperature is lowered to 80-100°C, additives T35143g and HiTEC8799B40.5g are added, and stirred for 20 minutes. Grind once with a colloid mill with a gap of 5 μ, then grind with a three-roll machine with a gap of 5 μ before / 2 μ behind, degas and pack to obtain the finished product.

Abstract

The invention provides an electric tool cylinder lubricating grease and a preparation method thereof. The lubricating grease comprises the following components: (a) a base oil which is phenyl silicone oil with a phenyl content of 30-40%, (b) a thickening agent which is fumed silica or organic bentonite, wherein the specific surface area of the fumed silica is 200-400m<2>g, and the organic bentonite is lithium-type bentonite, (c) an additive which is a composite agent of organic molybdenum salt and heavy-duty diesel engine oil. The above base oil, thickening agent and additive are prepared into the lubricating grease according to a certain ratio and a specified process. The lubricating grease can be used in lubricating and protection of various electric tools under harsh working conditions, especially tools such as electric hammer cylinders with harsh working conditions.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, and relates to a lubricant for an electric tool cylinder and a preparation method thereof, in particular to a high-phenyl silicone oil and an organic molybdenum salt for an electric tool cylinder with high temperature resistance, long service life and an impact frequency above 5200 Hz Grease and heavy-duty diesel engine oil compounding agent and preparation method thereof. Background technique [0002] An electric tool is a hand-held or movable mechanized tool that is powered by an electric motor or an electromagnet and drives the working head through a transmission mechanism. With the rapid development of industrial economy, China has become a big producer and consumer of electric tools. According to incomplete statistics, the annual consumption of lubricating grease in China's electric tool market is about 2,000 tons. However, the technology of electric tool grease products varies ...
