AI Technical Summary

Problems solved by technology

However, like other inorganic nanoparticles, tin antimony oxide nanoparticles are also prone to agglomeration, and if they cannot be well dispersed in the polymer matrix, their excellent functions will be reduced or even lost.
[0004] When preparing ATO nanoparticles, various techniques are used to reduce their agglomeration, but because agglomeration is a spontaneous phenomenon, only relying on improving the preparation technology cannot fundamentally solve the problem of agglomeration

Abstract

The invention discloses a functional film for shielding infrared rays, andbelongs to the technical field of optical films. The functional film is prepared from a composite emulsion containing modifiedtin antimony oxide nanoparticles, wherein the modified tin antimony oxide nanoparticles are modified through theaflavin-3-gallate, the particle size is small, the dispersity is good, and the particlesize distribution range is within the range of 20-120 nm. Due to the fact that the modified antimony tin oxide nanoparticles are adopted for preparing the functional film, the light transmittance ofvisible light reaches 80% or above, the light transmittance of infrared rays reaches 10% or below, and the corrosion resistance effect is improved by 20%; the functional film is prepared from trimethyl 1, 3, 5-benzotrihydroxy acid ester and vanillin isobutyrate, the adhesive force of the prepared functional film is improved, and the optimal effect reaches the zero level.

Description

technical field [0001] The invention belongs to the technical field of optical films, and in particular relates to a preparation method of a functional film shielding infrared rays. Background technique [0002] In hot summer, the radiant heat of sunlight directly entering the room through windows is the main cause of indoor overheating. About 29% of the energy of high-rise buildings comes from the radiant energy of sunlight. In hot climate areas, this figure can be close to 40%. The high-performance selective shielding material can make the glass have a selective transmission function for the spectrum. On the premise that it can pass through most of the visible light without affecting lighting, it can also block infrared heat radiation, thereby reducing the damage of air-conditioning or heating devices. Energy consumption, to achieve the purpose of energy saving. [0003] Tin oxide ladder nanoparticles have high visible light transmittance, infrared shielding (including ne...
