Abstract

The invention relates to organic silicon sealing adhesive with toughness, which belongs to the technical field of organic silicon sealing adhesive. The organic silicon sealing adhesive is prepared from dihydroxy polydimethylsiloxane, dimethicone, dimethyl dibutanoneoximido silane, methyltris(dimethylketoxime) silane, polyethylene glycol, fused white carbon black, nanoscale calcium carbonate, methyltriacetoxysilane, Di-t-butoxydiacetoxysilane, bis(lauroyloxy)dioctyltin and polyethylene terephthalate. After the organic silicon sealing adhesive is cured, the product has certain shape stability and deformation-resisting toughness.

Description

technical field [0001] The invention relates to a sealant, more specifically, the invention relates to a tough silicone sealant, which belongs to the technical field of silicone sealants. Background technique [0002] In the packaging of some electronic products or other products, it is often required that the silicone sealing material not only has a certain degree of flexibility, but also has a certain degree of toughness, so as to meet the normal use of such electronic products under some special environmental conditions. This requires the sealing material to have mechanical properties of a certain modulus and high elongation after curing. At the same time, the cured product is required to have certain shape stability and deformation resistance. Therefore, this new type of silicone sealing material has become a research hotspot. [0003] The State Intellectual Property Office published an invention with the publication number CN101768420A on 2010.07.07, titled "A dealcoh...
