Abstract

The invention relates to the field of air purification materials, and discloses a light-transmitting fiber-glass screen netting for air purification and a preparing method. The preparing method includes the following steps that (1) molybdenum salt, thiourea and hydrotalcite are added into deionized water and stirred, the pH value is adjusted to 2 to 3, molybdenum disulfide generated through a hydrothermal reaction is composited with the hydrotalcite, cooling, washing and drying are carried out, and then a molybdenum disulfide-hydrotalcite complex is obtained; (2) glass is melted, then the melted glass and the molybdenum disulfide-hydrotalcite complex are mixed and subjected to spinning and net laying, and a composite net film is prepared; (3) bismuth sulfide generated through the compositenet film and molybdenum disulfide form a heterostructure nanometer sheet, and meanwhile the molybdenum disulfide and the bismuth sulfide are fixed in a glass-fiber microcrack defect to prepare the light-transmitting fiber-glass screen netting. The fiber-glass screen netting prepared with the method is compared with a traditional screen netting, the dispersibility of a molybdenum disulfide catalyst is good, the contact surface between the molybdenum disulfide catalyst and air is large, the visible-light catalytic activity is high, and the light-transmitting fiber-glass screen netting has the remarkable effects on air pollutant purification, deodorization, volatile organic compound degradation, sterilization, disinfection and the like; the preparing process is simple, the cost is relativelylow, and the light-transmitting fiber-glass screen netting has the good economic advantages and broad application prospects.

Description

technical field [0001] The invention relates to the field of air purification materials, and provides a light-transmitting glass fiber window screen for air purification and a preparation method thereof. Background technique [0002] Today's human society is facing two major problems of energy and environment. Energy shortage and environmental pollution seriously restrict the development of human society. On the one hand, the rapid development of society has increased human demand for energy; on the other hand, the burning of fossil fuels has caused serious environmental pollution and harm to the environment, posing a serious threat to human survival. It can be seen that environmentally friendly and clean new energy sources and efficient environmental pollution control technologies have become important issues facing the development of today's society. Therefore, the photocatalytic technology that can effectively utilize solar energy to produce hydrogen and can be used for ...
