Embodiment 1

[0075] The present embodiment provides a kind of curtain, and this curtain is to make through the following steps:

[0076] The polyimide film was fixed on a flat glass substrate, and then washed repeatedly with alcohol and deionized water; according to the formula shown in Table 1, each component was ground by a sand mill to obtain a coating; the coating was sprayed on the polyimide The surface of the imide film is dried at room temperature, and after the coating is cured to form a film, the polyimide film is removed from the glass substrate to obtain a curtain.

[0077] The light transmittance of the curtain and the polyimide film was tested with a grating spectrophotometer and a Fourier transform infrared spectrometer. Among them, the transmittance of the curtain to visible light was 65.6%, and the rejection rate to infrared was 99.4%. %, the blocking rate of ultraviolet rays is 63.1%; the transmittance of polyimide film to visible light is 86.0%, the blocking rate of infra...

Embodiment 2

[0083] This embodiment provides a curtain. The preparation process of the curtain is basically the same as that of Embodiment 1. The polyimide film used is the same as that of Embodiment 1. The only difference is that the formulation of the paint is different. Specifically, the paint used in this embodiment See Table 2 for the formula.

Abstract

The invention provides a curtain and a preparation method thereof and a window curtain. The curtain comprises a base film and a reflecting layer, wherein the reflecting layer is a film layer formed bycoating the surface of the base film with a coating material comprising the following components in parts by weight: 1.5-2.5 parts of tin antimony oxide, 50-75 parts of fluorocarbon resin emulsion, 0.3-0.8 part of waterborne polyurethane resin, 0.03-0.08 part of sodium polyacrylate, 0.1-0.4 part of polyvinyl alcohol, and 32-40 parts of water and/or alcohol compounds. According to the curtain provided by the invention, infrared radiation and ultraviolet radiation can be effectively blocked, and visible light can smoothly pass through the curtain, so that the energy consumption of a glass window and the energy consumption of a building can be effectively reduced under the condition that indoor lighting is not influenced.

Description

technical field [0001] The invention relates to a curtain, a preparation method thereof and a curtain, in particular to a transparent curtain and a curtain capable of effectively blocking infrared rays and ultraviolet rays. Background technique [0002] Due to the needs of lighting and architectural aesthetics, a large number of buildings are designed with glass windows. However, because the transmission range of general glass overlaps with the solar radiation spectral region in a large range, so while passing through visible light and blocking ultraviolet rays, a large amount of infrared rays in sunlight pass through the glass window, resulting in an increase in indoor temperature and increasing the cooling capacity of indoor air conditioners. load, and will also affect building interior heat gain. Studies have shown that in hot summer, the energy consumption of glass windows can even reach about 50% of the energy consumption of the entire building. [0003] In order to r...
