Sound absorption cotton with easily torn double-sided adhesive tape and processing method and equipment of sound absorption cotton

Abstract

The invention discloses sound absorption cotton with an easily torn double-sided adhesive tape and a processing method and equipment of the sound absorption cotton and in particular relates to the technical field of sound absorption cotton. The sound absorption cotton comprises an inner sound absorption cotton protection layer, a sound absorption layer and an outer sound absorption cotton protection layer, wherein the sound absorption layer is arranged between the outer sound absorption cotton protection layer and the outer sound absorption cotton protection layer; the inner sound absorption cotton protection layer is arranged on the innermost side of the sound absorption cotton as a whole; a mosquito expelling bag is mounted between the sound absorption layer and the inner sound absorption cotton protection layer; a double-sided adhesive tape is arranged on the outer surface of the inner sound absorption cotton protection layer; release paper is connected with the outer side of the double-sided adhesive tape; and an easy tearing strip is arranged on the edge of one end part of the release paper. When being used, the sound absorption cotton is capable of both expelling mosquitoes and promoting human health, the problem that conventional sound absorption cotton is single in function and other effects cannot be taken into play can be solved, the easily tearing strip can be conveniently torn off to bond the sound absorption cotton into a vehicle in the use process, and in addition, the situation that the viscosity of an adhesive is affected as the double-sided adhesive tape isbent as one end of the easily tearing strip protrudes out can be avoided.
