Preparation method and application of plastic net for capturing dust by utilizing static electricity

Abstract

The invention belongs to the technical field of new material processing, and particularly relates to a preparation method and application of a plastic net for capturing dust by utilizing static electricity. The preparation method comprises the following steps that after a plastic raw material is dried, and is mixed with electrostatic additive master batch to be fed into a screw extruder for five-zone heating melting; then a mixture enters a cold water tank for being cooled and formed in a spinning die head, is drawn by hot water of a group of drawing devices, bundles are collected and wound ona pan head, pan head is placed, frame wires are uniformly arranged for being weaved in a warp knitting machine, and is weaved into plastic net cloth; and corona discharge electret is carried out on the net cloth by direct-current high-voltage electricity to obtain the plastic net cloth for capturing the dust by utilizing the static electricity. The plastic net for capturing the dust by utilizingthe static electricity can be applied to adsorption window gauze, an air purifier, an intelligent air conditioner, air purification integrated equipment, an automobile air conditioner or a protectivemask. The net is uniform and stable in electrostatic charge distribution, high in electrostatic field intensity and high in capacity of adsorbing dust in air, and various properties of the electrostatic net are improved.

technical field

[0001] The invention belongs to the technical field of new material processing, and in particular relates to a preparation method and application of a plastic net that uses static electricity to capture dust. Background technique

[0002] In modern society, the blind pursuit of rapid economic development has resulted in serious environmental pollution, leading to a decline in air quality and an increase in the content of PM2.5 in the air. These harmful particles, dust and other tiny particles can affect the respiratory organs of the human body and cause harm to the human body. Therefore, indoor air purification has attracted more and more attention from people. Therefore, the development momentum of purification equipment such as adsorption window screens, air purifiers and intelligent air conditioners is strong, and the rigid demand in the market is large, which gives a huge application market space for electrostatic adsorption nets.
