| description | The invention provides a deacetonized two-component silicone rubber sealant. The deacetonized two-component silicone rubber sealant is prepared from a component A and a component B in the weight ratio of 2: 1 to 20: 1, wherein the component A comprises the following materials in parts by weight: 100 parts of alpha, omega-dihydroxyl polydimethylsiloxane and 10-500 parts of solid filler; the component B comprises 100 parts of alpha, omega-dihydroxyl polydimethylsiloxane, 2-40 parts of a deacetonized silane crosslinking agent, 2-20 parts of an adhesion promoter, 10-200 parts of solid filler, 0.01-5 parts of catalyst and 0-50 parts of pigments. The deacetonized two-component silicone rubber sealant is excellent in adhesive property and ageing resistance (resistance to ageing conditions such as low temperature, weather, ultraviolet and moist heat), and is better in high temperature resistance and higher in curing speed than the dealcoholized two-component silicone rubber. |
