Abstract

A high-performance acidic transparent silicone sealant belongs to the technical field of the adhesive. The sealant comprises the following components in parts by weight: 90-130 parts of hydroxyl-terminated polydimethylsiloxane, 10-60 parts of alkyl-terminated polydimethylsiloxane, 5-15 parts of crosslinking agent, 20-90 parts of silicon dioxide, 0.01-0.9 part of anti-yellowing agent and 0.005-0.15 part of catalyst, wherein crosslinking agent is the mixture of methyltriacetoxysilane and ethyltriacetoxysilane; anti-yellowing agent is one or more of ultraviolet absorbent and light stabilizer; and catalyst is dibutyltin diacetate or dibutyltin dilaurate. The invention does not depend on the foreign product and provides the high-performance acidic sealant so as to fills the gap that neutral transparent silicone sealant can not be used in the glass fishbowl; and the sealant has good bonding property to the substrate, and can not have blushing and yellowing and can have no pollution to the environment. The sealant can satisfy the demands of the specific curtain wall, glass roof and glass fishbowl.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a high-performance acidic transparent silicone structural sealant with high adhesion, anti-yellowing, high and low temperature resistance, and water-ultraviolet light resistance. Background technique [0002] Glass aquarium, glass lighting roof, point curtain wall, hanging glass curtain wall, hidden frame glass curtain wall and insulating glass have become an important part of modern architecture because of their light, thin and transparent characteristics. These are mostly made of transparent white glass and silver aluminum alloy profiles, bonded and sealed through structural assembly. At present, the sealant used is basically a colored sealant, which will turn yellow after drying, which will affect the overall effect of the curtain wall and the visual appearance of people, and the sealant used is not good because of poor adhesion, high and low temperature resistan...
