Problems solved by technology

However, in the process of mixing indium tin oxide into plexiglass, due to the small particle size of indium tin oxide, the chain segment of the polymer is longer, and the particles of indium tin oxide are easily agglomerated, which leads to the formation of indium tin oxide in polymer polymerization. Inhomogeneous distribution in the material leads to the poor ability of the prepared radiation-proof and heat-insulating polymer glass to block the infrared and ultraviolet regions

Abstract

The invention relates to radiation-proof thermal-insulation polymerized glass and a preparation method thereof, which belong to the technical field of the radiation-proof glass, and solves the disperse problem of indium tin oxide particles in polycarbonate synthetic glass. The radiation-proof thermal-insulation polymerized glass comprises the following raw materials in parts by weight: 100-120 parts of bisphenol A, 87-93 parts of diphenyl carbonate, 26-30 parts of indium tin oxide, 10-14 parts of potassium hydroxide, 50-60 parts of a solvent, 9-13 parts of acryloxy methyltrimethoxysilane, 11-21 parts of trimethoxyoctylsilane, and 3-9 parts of a dispersant. The transparency of the radiation-proof thermal-insulation polymerized glass is high, capability for blocking an infrared light zone and an ultraviolet light zone in solar spectrum is enhanced, and functions of heat insulation and radiation resistance can be achieved.

Description

technical field [0001] The invention relates to the technical field of radiation-proof glass, more specifically, it relates to a radiation-proof heat-insulating polymer glass and a preparation method thereof. Background technique [0002] Glass curtain wall is one of the outer enclosure structures that are widely used in modern buildings. It not only realizes the integration of walls, doors and windows in the outer enclosure structure of the building, but also ingeniously integrates the use function and device function of the building envelope. The integration makes the building more modern and decorative. At present, although ordinary inorganic glass is still commonly used in traditional buildings, due to the heavy quality of ordinary inorganic glass curtain walls, and the damage rate is almost 100% after being impacted by the outside world, the damaged glass fragments are very easy to cause harm to consumers, so inorganic glass Glass is not suitable for glass curtain wall...
