Abstract
The invention relates to the technical field of adhesives, and provides an oil-resistant organic silicon sealant and a preparation method thereof. The oil-resistant organic silicon sealant is preparedfrom the following components in parts by weight: 100-150 parts of alpha, omega-dihydroxypolysiloxane (107 silicone rubber), 10-20 parts of a ketoxime cross-linking agent, 1-3 parts of an amino silane coupling agent, 50-200 parts of a filler, 0.1-0.3 part of a tin catalyst, 10-50 parts of an oil-resistant additive and 2-10 parts of white carbon black. The problems that an existing oil-resistant organic silicon sealant is high in manufacturing cost, poor in high-temperature resistance and the like are solved.
Description
technical field [0001] The invention relates to the technical field of adhesives, in particular to an oil-resistant silicone sealant and a preparation method thereof. Background technique [0002] Silicone rubber sealants are widely used in automobile, construction, petrochemical, machine manufacturing and other industries. In the automobile manufacturing industry, silicone sealants are widely used for forming sealing gaskets in place, and are often used for sealing of engines, rocker shafts, timing chain covers, oil filter covers, bearing caps, valve covers, coolant systems, etc. The requirements for sealing rings used in automobile engines are very strict, requiring high temperature resistance, oil resistance and low compression set. [0003] Silicone sealants use hydroxyl-terminated polysiloxane as the base polymer, and add other additives at the same time. Silicone sealant not only has weather resistance, heat resistance, cold resistance and adhesiveness, but also has ...
