Abstract

The invention discloses a fluorescent silicone sealant for glass decoration. The transparency of the sealant is up to 70-85%. The fluorescent silicone sealant is characterized by comprising the following raw materials in parts by weight: 85-110 parts of hydroxyl-terminated dimethylsiloxane, 10-25 parts of a plasticizer, 10-25 parts of silica, 0.1-2 parts of fluorescent powder, 6-9 parts of a cross-linking agent and 0.01-0.3 part of a catalyst. When adopted for adhesion, the silicone sealant has a transparent fluorescent glare effect under light irradiation after used, has the characteristics of high adhesive property, high / low-temperature resistance and excellent water resistance, and is particularly applicable to adhesion and seal of fishbowls, glass daylighting roofs, hanging glass and other materials needing decorative effects.

Description

technical field [0001] The invention relates to the field of sealant materials, in particular to a fluorescent silicone sealant for glass decoration and a preparation method thereof. Background technique [0002] Silicone sealant is a kind of ointment-like material that solidifies into a tough rubber-like solid material when exposed to moisture. It has strong adhesion and high tensile strength. It also has weather resistance, vibration resistance, moisture resistance, and odor resistance. The characteristics of air and adaptability to large changes in cold and heat, coupled with its wide applicability, can realize the bonding between most building materials. At present, the colors of organic silicone sealants on the market mainly include transparent, black, porcelain white, silver gray, etc., and transparent fluorescent colors without decorative effects. Now people are more and more demanding for perfection in the pursuit of beauty, especially in the bonding and sealing of ...
