Ear belt type multi-layer composite mask and production method thereof

Abstract

The invention relates to an ear belt type multi-layer composite mask and a production method thereof, the ear belt type multi-layer composite mask comprises a left mask body and a right mask body which are symmetrical to each other, and the left mask body and the right mask body respectively comprise an ear hanging part and a ventilation part which are integrally formed by blanking a composite material; the composite material is formed by compounding an antibacterial coating, a polyester cotton base layer and an outer cover, the antibacterial coating is formed by spraying an antibacterial agent on the surface of one side, far away from the outer cover, of the polyester cotton base layer, and the antibacterial agent is octadecyl dimethyl (3-methoxysilylpropyl) ammonium chloride; the outer cover is a polyester film punched with air holes; arc-shaped spines located on the center line of the mask are formed on the edges of the ventilation parts of the left mask body and the right mask bodythrough ultrasonic welding, protection sections without ultrasonic welding are arranged between the upper ends and the lower ends of the spines and the edge of the mask, and the hardness of the protection sections is smaller than that of the spines to form a buffering protection structure for preventing the end faces of the spines from scratching human skin. The polyester film punched with the air holes forms the outer cover, so that the windproof performance of the mask is improved, the air permeability of the mask is reduced, and the filtering performance is enhanced.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a dust-proof and haze-proof ear-loop type multi-layer composite mask. Background technique [0002] As the society pays attention to hot spots such as air pollution and virus droplet transmission, masks have become a must-have item for families. Among them, ordinary sponge masks have the characteristics of beautiful appearance and have a certain protective effect on large particles. Some manufacturers have made sponge masks On the basis of increasing the complex filtering structure, the protective effect of the sponge mask is improved, such as the anti-smog sponge mask disclosed in the Chinese utility model patent with the application number CN201720999086.2. Filter inhalable particulate matter and improve the filtering effect of the sponge mask, but setting a support frame and a breathing valve on the mask greatly increases the weight of the sponge mask. When the spong...

[0002] As the society pays attention to hot spots such as air pollution and virus droplet transmission, masks have become a must-have item for families. Among them, ordinary sponge masks have the characteristics of beautiful appearance and have a certain protective effect on large particles. Some manufacturers have made sponge masks On the basis of increasing the complex filtering structure, the protective effect of the sponge mask is improved, such as the anti-smog sponge mask disclosed in the Chinese utility model patent with the application number CN201720999086.2. Filter inhalable particulate matter and improve the filtering effect of the sponge mask, but setting a support frame and a breathing valve on the mask greatly increases the weight of the sponge mask. When the sponge mask is worn on both ears, it greatly increases the burden on the ears. After wearing it for a long time, it will make the ear and the mask contact position red and even painful; therefore, it is necessary to design a mask that further improves the filtering and protective effect of traditional sponge masks without excessively increasing the weight of the sponge mask
