Abstract

The invention provides a dealcoholization type silicone sealant which comprises the following components by mass percent: 48-51% of dimethyl siloxane hybrid ring or octamethyl cyclotetrasiloxane, 3-5% of 201 methyl silicone oil, 38-40% of nano active calcium carbonate, 5-5.5% of pigment, 3.5-4.5% of cross-linking agent, 1-1.2% of thickening agent, 1.3-2% of titanium catalyst and 0.1-0.15% of tin catalyst. The invention also provides the production method of the dealcoholization type silicone sealant. The dealcoholization type silicone sealant and the production method thereof are suitable for continuous production; the produced adhesive cement is excellent in performance, good in storage stability and superior in combination property; furthermore, the product quality is improved, the loss is reduced, the energy is saved and the work environment of workers is improved.

Description

technical field [0001] The invention relates to the field of polymer sealing materials, in particular to a dealcoholized silicone sealant and a production method thereof. Background technique [0002] Silicone polymer materials have a series of unique properties, such as: excellent weather aging resistance, excellent high and low temperature resistance, good hydrophobicity, excellent biocompatibility, etc., and are widely used in construction, transportation, automobiles, etc. , electronics, aviation, aerospace, textile, machinery, chemical industry, medicine, personal care products (cosmetics) and more than dozens of industrial sectors and daily life have played an irreplaceable role for other synthetic materials. Silicone materials are widely used in construction, mainly sealants with different properties, which are characterized by excellent weather resistance, and the performance changes little within 30 years under general climate conditions, which is difficult for othe...
