Single-component deketoxime type silicone sealant containing sulfydryl-amino and preparation method of single-component deketoxime type silicone sealant

The invention provides a single-component deketoxime type silicone sealant containing sulfydryl-amino and a preparation method of the single-component deketoxime type silicone sealant, and relates to the field of organic sealant materials. The preparation method comprises the following steps: reacting aminopropyltrimethoxysilane with diaminothiourea to synthesize a sulfydryl-aminopropyltrimethoxysilane-containing coupling agent, adding the sulfydryl-aminopropyltrimethoxysilane-containing coupling agent into alpha, omega-dihydroxy polydimethylsiloxane, a reinforcing filler, a plasticizer and a cross-linking agent, and uniformly stirring to obtain a mixture; the modified coupling agent containing sulfydryl, primary amino and secondary amino is added into components of a common organic silicon sealing material, and the adhesive property can be met by adding a small amount of the modified coupling agent, so that the requirement of a single-component sealant material on the adhesive property of a base material is
