Abstract:
1. An addition-type organosilicon composition comprising: A) 100 parts (by weight) of vinyl silicone oil; B) 10-500 parts (by weight) of silicon dioxide treated by silane or 20-1500 parts (by weight) of aluminium oxide treated by silane; C) a compound in which every molecule of the compound contains a H—Si functional group, wherein a mass content of H in the H—Si functional group is 0.1-1.2%; D) 0.1-5 parts (by weight) of a first product by a reaction between Vinyl trimethoxy(triethoxy) silane and γ-2,3-epoxy propoxy) propyl trimethoxy(triethoxy) silane, or 0.1-5 parts (by weight) of a second product by a reaction between the first product and γ-aminopropyl trimethoxy(triethoxy) silane; E) 2-200 ppm of Chloroplatinic acid or 1,3-divinyl-1,1,3,3-tetramethyl disiloxane platinum complex; and F) 0.01-50 parts of any one or combination of carbon black, iron black, titanium dioxide, cerium oxide, benzotriazole, zinc carbonate, and magnesium carbonate; wherein a molecular ratio of the H—Si functional group and vinyl from the vinyl silicone oil in the composition is 0.6-3, and a grain size of the silicon dioxide treated by silane or the aluminium oxide treated by silane is 1-50 μm.
