Abstract

The invention discloses a silicone sealant and a preparation method thereof. The silicone sealant is characterized by comprising the following components: silicon sulfide rubber, methyl MQ silicon resin, petroleum resin, hydroxyl sealed polydimethylsiloxane, alkyl sealed polydimethylsiloxane, white carbon black, a catalyst, a plasticizer, a cross-linking agent and a coupling agent. The preparation method comprises the following steps: by adopting a quantitative feeding device, adding silicon sulfide rubber, methyl MQ silicon resin, petroleum resin, hydroxyl sealed polydimethylsiloxane, alkyl sealed polydimethylsiloxane and white carbon black into a negative / positive device, uniformly stirring and mixing, vacuuming, adding the catalyst, the plasticizer, the cross-linking agent and the coupling agent, mixing in vacuum, reacting for 1-10 hours, filtering by using a filtering device, filling by using an automatic filling device, and storing, thereby obtaining the silicone sealant. The invention aims at providing the silicon sealant which is reasonable in component and proportioning and good in adhesion property, and the preparation method of silicone sealant.

Description

technical field [0001] The invention relates to a silicone sealant, and also relates to a method for preparing the silicone sealant. Background technique [0002] Adhesive refers to a kind of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through the adhesion and cohesion of the interface, collectively referred to as glue. Adhesives, also known as adhesives, are customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding; traditional adhesives have poor adhesion due to unreasonable formula ratios and cannot meet the needs of use. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a silicone sealant with reasonable components and ratio and good bonding performance. [0004] Another object of the present invention is to provide a method for preparing the silicone sealant....
