Abstract

The invention relates to special resin for a solar film and a preparation method thereof, wherein the special resin comprises the following raw materials in parts by weight: 3-5 parts of polyvinyl alcohol, 1.5-2.5 parts of butyraldehyde, 0.15-0.25 part of ethanol, 0.015-0.025 part of ultraviolet obstructing agent, 0.015-0.025 part of infrared obstructing agent, 0.1-0.3 part of dispersant, 0.06-0.08 part of pigment, 0.03-0.05 part of antioxidant, 0.3-0.5 part of reagent-grade hydrochloric acid, 0.3-0.5 part of alkaline auxiliary agent and 30-50 parts of pure water. The invention realizes the action of blocking ultraviolet rays and infrared rays, can achieve 99 percent of obstruction rate and has the advantages of high anti-impact strength and stability and good film-forming performance; and the reaction is carried out at normal temperature, therefore, the production cost is lowered. The solar film made of the special resin can be widely applied to the glass for automobile windows, building windows, and the like; and compared with like products, the heat insulating effect of the solar film made of the special resin is markedly improved under the condition of identical light transmittance index.

Description

technical field [0001] The invention relates to a resin for solar film, in particular to a resin for making solar film for automobile window glass and building glass. Background technique [0002] At present, there are many solar film products in the international market, and the requirements for solar film materials generally have the characteristics of light blocking, heat insulation, and certain decorative effects. The existing solar film products are mainly products from the United States, South Korea, and Taiwan. For example, the most used big brand products include: Long film, Weigu solar film, Federation Suntech solar film and Johnson & Johnson solar film. The solar film of these big brands Although the film products can achieve 99% ultraviolet and infrared blocking rate, the production process of solar film is complicated, and the price is high, the cost is high, and the heat insulation effect is not very ideal. There are hundreds of solar film brands in the domesti...
