Abstract

A silicone rubber sealant comprises the following components, by weight: 40-60 parts of modified polydimethylsiloxane, 20-40 parts of calcium carbonate, 5-10 parts of white carbon black, 1-10 parts of vinyltris (methylethylketoxime) silane, 1-3 parts of ethyl methyl ketone oxime and 2-10 parts of barium sulfate. The invention also provides a preparation method for the silicone rubber sealant. The silicone rubber sealant of the invention has relatively good instant sealing performance.

Description

technical field [0001] The invention relates to the field of sealing materials, in particular to a silicone rubber sealant for engines and a manufacturing method thereof. Background technique [0002] Sealant is an adhesive used to fill the configuration gap to play a sealing role. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. Sealants are widely used in the field of automobile manufacturing, which can simplify the production process, save materials, and enhance the strength of components, especially in shockproof heat insulation, anti-corrosion, anti-rust, leak-proof, anti-loosening, noise reduction, self-weight reduction, comfort and safety, etc. It has a special role and has become an indispensable material in automobile production. Sealant can be applied to different parts of the car, especially the most common one is applied to the engine of the car to solve the problems of water leakage, oil leakage and air lea...
