Process for producing electrically heating mosquito-repellent incense raw paper sheet

Abstract

The production process of electrically heating mosquito repellent incense raw paper sheet features the silk screen printing process to print composite layer to the surface of the raw paper sheet. The composite layer comprising silver powder, aluminium powder, gold power or copper-gold powder may be produced into letters or figures. The present invention has high air permeability, is favorable to air convection and chemical evaporation. In addition, it has the advantages of homogeneous coating, homogeneous chemical liquid evaporation, high mosquito repellent effect, saving in material and low dust working condition.

Description

(1) Technical field: [0001] The invention relates to a processing method of an electric heating mosquito coil base paper sheet. It belongs to the technical field of daily necessities. (two) background technology: [0002] Electric heating mosquito-repellent incense raw paper, as a carrier of mosquito repellent, has been widely used. However, since the main raw material of the original paper sheet is plant fiber, the heat conduction effect is poor, and it is not attractive in appearance. The heat transfer of the electric heating mosquito-repellent incense sheet made therefrom is slow, which is not conducive to the volatilization of the medicament, and the mosquito repellent effect is not ideal. For this reason, two kinds of improved electric heating mosquito-repellent incense raw paper sheets have appeared on the market: one is to add an aluminum foil composite layer on the raw paper sheet surface, and the other is to spray a silver powder composite layer on the raw paper sh...

AI Technical Summary

Problems solved by technology

[0003] The electric heating mosquito-repellent incense base paper sheet with aluminum foil on the surface, because it is compounded or coated with aluminum foil on the PET film first, and then pasted on the base paper sheet, has no air permeability and cannot form air convection, which is not conducive to the volatilization of the medicine and repells mosquitoes. The effect is less ideal;

[0004] The electric heating mosquito-repellent incense base paper sheet sprayed with silver powder on the surface, because some silver powder and other substances diffuse in the air during the processing process, it is not conducive to the health of the operator, pollutes the environment, and wastes raw materials. At the same time, the thickness of the coating is uneven and the surface conducts heat. There are differences in the properties, the volatilization speed of the liquid medicine is inconsistent, the product quality is unstable, and the mosquito repellent effect is poor.
