Problems solved by technology

During the preparation process of ATO nano thermal insulation slurry, it is easy to form aggregates due to the surface force of ATO particles and the existence of bridge bonds. During the storage process of ATO nano thermal insulation slurry, a high sedimentation rate will occur, thus causing the current The storage time of ATO nano thermal insulation slurry in the market is short, which leads to the limited use of this product in the process of use and promotion

Abstract

The invention discloses alcoholic nano transparent infrared thermal insulation anti-sedimentation slurry and a preparation method thereof. The alcoholic nano transparent infrared thermal insulation anti-sedimentation slurry comprises the following components in parts by mass: 8-12 parts of ATO nano stibium-doped tin dioxide, 3-6 pats of an alcohol solvent, 5-10 parts of a D type dispersant, 6-12 parts of P type dispersant and a pH adjustor; the D type dispersant is macromolecular multivalent carboxylate, the P type dispersant is methyl silicate, and the dosage of the pH adjustor is based on adjustment of the pH value of the slurry to 8-10. According to the slurry and the preparation method, the sedimentation rate of the ATO nano thermal insulation slurry in an alcohol solvent is effectively reduced, the dispersing effect and stability of the slurry are enhanced, and the storage time of the slurry is prolonged.

Description

technical field [0001] The invention relates to the field of building energy-saving glass heat-insulating slurry, in particular to an alcohol-based nano-transparent infrared heat-insulating and anti-settling slurry and a preparation method thereof. Background technique [0002] In the building envelope, the thermal performance of glass has always been the biggest factor affecting building energy consumption and human comfort. Ordinary single-layer glass usually produces a large energy loss in the building envelope, especially when the indoor and outdoor temperature difference is large, the air-conditioning load will be lost by 20-30% through the glass, resulting in energy consumption. In order to improve the heat insulation performance of glass and reduce building energy consumption, various forms of energy-saving glass such as filmed glass and coated glass have appeared on the market in recent years, which have achieved the purpose of building energy conservation to a large...
