Problems solved by technology

Although there are components that can be cured at room temperature in existing coatings containing organic binders, the film strength after coating and curing is weak, so it is not practical; on the other hand, if inorganic binders such as silicates If the compound is used, the film strength after hardening is practical, but since it will not harden at room temperature, it needs to be heated to harden, resulting in poor productivity and high cost; Shrinkage is large and will cause cracks

Abstract

The invention provides a novel high-performance solar shading paint and related adhesives, solar shading film and base material, wherein the novel high-performance solar shading paint includes an adhesive, a near-infrared ray shielding agent and an ultraviolet absorber, and its characteristics In that, the binder includes a compound represented by formula (I), and X of the compound of formula (I) is an alkoxy group. The coating can not only be cured to form a film at normal temperature, but also the obtained hardened film has high sunlight shielding ability and high surface hardness. The coating is ingenious in design, easy to prepare and low in cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The present invention relates to the technical field of solar shading materials, in particular to the technical field of solar shading coatings, specifically a novel high-performance solar shading coating, related adhesives, solar shading films and substrates. Background technique [0002] Sunlight can be roughly divided into three types: near-infrared rays, visible rays, and ultraviolet rays. Among them, near-infrared rays (hot rays) in the long-wavelength region are mainly perceived by the human body in the form of heat energy, which is the cause of temperature rise in indoors and cars. In addition, ultraviolet rays in the short-wavelength region can cause sunburn, chloasma, freckles, carcinogenesis, and visual impairment to the human body. It can also cause deterioration of the mechanical strength of articles, deterioration of appearance such as fading, and reduction of the color tone of printed matter. In order to shield these unnecessary heat rays...
