Abstract

The invention provides a sealant used for hollow glass, containing the following components in parts by weight: 50-60 parts of organic hydroxyl silicone, 10-14 parts of organic methyl silicone, 6-12 parts of methyl silane, 25-35 parts of inorganic filler, 10-16 parts of high-temperature resistant accessory, 1-3 parts of nano zirconium oxide, 1-3 parts of amino silicon, 1-2 parts of dibutyltin dilaurate, 12-16 parts of rubber, 1-2 parts of a bonding assistant, 8-10 parts of a plasticizer, 1-3 parts of an antibacterial agent, and 0.2-0.6 part of an ultraviolet absorbent; the high-temperature resistant accessory is prepared by mainly taking nanometer magnesia-alumina hydrotalcite as a matrix and graphene oxide as an assistant, and performing hot pressing and sintering at the temperature of 250-350 DEG C. The sealant has good flame retardance and high temperature resistant performances, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of sealing materials, and in particular relates to a sealant for insulating glass. 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. 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 main materials are glass, warm edge spacer, angle bo...
