A kind of heat reflective coating cloth

Abstract

The invention discloses a heat-reflective coated cloth, which comprises: a base cloth layer, a reflective heat-insulating primer layer and a reflective heat-insulated top coat layer, wherein the reflective heat-insulated primer layer is formed by the first coating The slurry is solidified, the first coating slurry contains anionic emulsion, aqueous solvent, titanium dioxide, anti-settling agent, foaming agent, dispersant and leveling agent, and the reflective heat insulation surface coating is formed by the second coating slurry The second coating slurry contains anionic emulsion, aqueous solution, titanium dioxide, near-infrared reflective pigment, anti-settling agent, defoaming agent, dispersant and leveling agent. The heat reflective coating cloth of the invention has double reflective effect on solar heat radiation and can effectively block heat transfer.

Description

technical field [0001] The invention relates to the field of applied chemistry, in particular to a heat reflective coating cloth. Background technique [0002] Most of the earth's energy comes from the sun. The sun provides protection for human production and life, but at the same time strong solar radiation also brings a lot of inconvenience. According to statistics, the energy consumed by cooling and cooling accounts for about 20% of the total energy consumption in the world every year. Therefore, reducing the energy of solar radiation is the main method to reduce the energy consumption caused by the heat of the sun. [0003] Textiles are closely related to people's production and life, and have a wide range of uses. They can be used in households, offices, construction, high-speed rail, automobiles, ships, refrigeration, agricultural greenhouses, and other fields. They can be made into curtains, car covers, tents, parasols, clothing, etc. Products are often used to block...

AI Technical Summary

Problems solved by technology

However, most of the solar heat radiation reflective and heat-insulating textiles on the market are in the research and development stage. Similar textile products with reflective heat-insulation function have poor flexibility, easy to fall off reflective layer, poor decoration, poor water resistance, low reflectivity, and single color. (only white) and other shortcomings, unable to meet the requirements of various fields

[0004] CN103469576A discloses a coated non-woven fabric, which has improved air permeability, decoration and wear resistance, but has no significant improvement in the reflection effect of sunlight and the heat insulation effect

But this method exists that the reflection effect to sunlight is not obvious, especially the reflection effect to the near-infrared band (400-2500 nanometers) of sunlight is relatively poor, and the heat energy carried by the near-infrared band in solar thermal radiation accounts for 100% of the sun's energy. More than 53% of the total thermal radiation, obviously, effectively reducing the thermal radiation in the near-infrared band has an important impact on the final cooling result. In addition, the color is single (only white), so it is necessary to have a heat-insulating effect that is good for solar thermal radiation. Coated cloth with high reflectivity (including reflection of visible light and near-infrared bands) and good decoration
