Abstract
The invention relates to a sealing material, in particular to a flame-retardant siliconesealant for hollow glass. The flame-retardant siliconesealant is prepared from polymethylhydrosiloxane, (6-methoxy-4-quinolyl)(5-vinyl-1-diazabicyclo[2.2.2]octane-2-yl)methanol, 3beta-hydroxypregn-5,16-diene-20-ketone, 1,1,3,3-tetramethoxypropane, 2-acrylic acid 2-(4-benzoyl-3-hydroxyphenoxy)ethyl acrylate and the like. The flame-retardant siliconesealant for the hollow glass is good in sealing effect, high in flame-retardant rating, excellent in various mechanical properties, simple in preparation method, high in construction efficiency, long in preservation time and suitable for being applied and popularized in the field of silicon sealants for the hollow glass.
Description
technical field [0001] The invention relates to a sealing material, in particular to a flame-retardant silicone sealant for insulating glass. Background technique [0002] Insulating glass was invented by Americans in 1865. It is a new type of building material with good heat insulation, sound insulation, aesthetics and applicability, and can reduce the self-weight of buildings. It uses two (or three) pieces of glass and uses high strength and high strength. The airtight composite adhesive is used to bond the glass sheet to the aluminum alloy frame containing the desiccant to form a high-performance sound-insulating and heat-insulating glass. 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...
