Abstract

The invention discloses a sealant for antibacterial flame-retardant hollow glass, belonging to the technical field of sealants. The sealant contains the following raw materials in parts by weight: 55-60 parts of organic hydroxyl silicone, 14-16 parts of organic methyl silicone, 7-13 parts of methyl silane, 12-14 parts of fumed silica, 8-10 parts of zinc borate, 2-4 parts of zirconium dioxide, 6-8 parts of calcium carbonate, 1-5 parts of titanium dioxide, 6-8 parts of decabromodiphenyl ethane, 1-2 parts of dibutyltin dilaurate, 3-5 parts of amino silane, 15-17 parts of ethylene-propylene- diene-terpolymer rubber, 1-2 parts of acetic acid, 1-3 parts of olive oil, a proper amount of water, 1-3 parts of antibacterial agent, 9-11 parts of plasticizer, and 1-2 parts of bonding agent. The invention further discloses a preparation method of the sealant for antibacterial flame-retardant hollow glass. The sealant is flame-retardant and high-temperature-resistant, antibacterial and long in service, excellent in bonding capacity, and excellent in mechanical strength.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to a sealant for antibacterial and flame-retardant hollow glass and a preparation method thereof. Background technique [0002] Insulating glass is a new type of building material with good heat insulation, sound insulation, aesthetics and applicability, and can reduce the weight of buildings. [0003] It is a high-efficiency sound-insulating and heat-insulating glass made of two or three pieces of glass, using a high-strength and high-air-tight composite adhesive to bond the glass pieces to the aluminum alloy frame containing the desiccant. The performance of insulating glass is superior to that of ordinary double-layer glass, so it has been recognized by all countries in the world. Insulating glass is to separate two or more pieces of glass evenly with effective support and bond and seal the periphery, so that a dry gas is formed between the glass layers. Space glassware. Its m...
