Objects sustained sunlight can accumulate a lot of heat, leading to the rise of the surface and the inside temperature, especially in the hot summer and the high-temperature region, bring a lot of inconvenience and harm to the people's production and life. With the intensification of the global warming trend around the world frequently reported record high temperature; destruction of the ozone layer, leading to global dermatology patients increased, especially in the southern hemisphere and the Guangdong region of China. Outdoor production of these environmental issues to the people living inconvenience. At the same time, with the improvement of people's living standards, and the implementation of the trend of returning to nature, people increasingly prefer to participate in outdoor activities. Requirements related products on the market to solve this problem or weaken the harm caused by this phenomenon. First, to meet the people's basic production and living needs; Furthermore, we need to adapt to the outdoor environment, it has UV protection, waterproof, ventilation breathable, flame retardant of antifouling and blackout reflection special features. To solve this problem, it designed a variety of protective heat radiating method, wherein a commonly used is infrared heat reflective coating, the so-called infrared heat reflective coating is coated on the surface of objects, the radiation in the infrared band having a high reflectance, thereby suppressing the temperature of the coating surface increased and at the same time to reduce the internal temperature of the covering layer. Currently, the domestic insulation for cooling insulation coatings development, production mainly for the construction industry, industrial equipment, and aviation and other fields, the study, tents and other outdoor textiles cooling insulation coatings barely, rarely relevant for the textile industry coatings reported. The purpose of this project is to develop a beach umbrella, tents and other outdoor textiles cooling insulation coatings to reduce under the umbrella of the temperature inside the tent, and to provide a more comfortable working and living environment for the user. Coatings for insulation previous studies the most heat-reflective coatings, in fact, based on the different ways of the insulation mechanism and insulation, thermal insulation coatings can be divided into three types: barrier, reflective and radiation type insulation coatings. In this project will try to use two or three insulation mechanism, developing multi-mechanism, the a cooling insulation effect is more pronounced insulation paint. This topic than the apparent effect of the coating fabric, anti-UV effect to the coating the cooling insulation combined effect, cooling insulation coating solar heat absorption, tear strength, tensile strength and resistance to hydrostatic do this paint The performance indicators, screening of a film-forming component, functional fillers and additives, and to determine the composition and amount of each component. Eventually, the coating developed by the subject through the the appropriate coating process finishing fabrics, cooling insulation effect up to 23 ° C, the solar heat endothermic ratio as low as 21.90%, UV resistant, water repellent, tensile strength and tear strength the performance indicators are more than the standard value. View of the cooling insulation textiles little studied, is not the appropriate test instruments and standards in the industry, the subject according to the characteristics of textiles homemade combined effect of cooling insulation tester and creative leads solar heat absorption ratio formula, quantitative description of the present The subjects developed coating insulation cooling effect, good or bad.
