Problems solved by technology

[0003] The present invention aims to solve the technical problem that the surface of the adhesive tape often has air bubbles, pinholes, and spongy phenomena due to the consistent vulcanization point of each layer of adhesive tape in the production process of the current multi-layer adhesive tape, which causes the surface of the adhesive tape to be loose, rough, and has extremely poor protective performance. Production method of laminated adhesive tape

Abstract

The invention relates to a production process of an adhesive fabric, particularly relates to a production method of a multi-layer composite adhesive fabric, and solves the technical problem that the adhesive fabric is loose and coarse in surface and extremely poor in protection property due to the fact that bubble, pinhole and sponge phenomena often exist on the surface of the adhesive fabric as a result of identical curing points of each adhesive layer in the multi-layer adhesive fabric production process in the prior art. The production method of a multi-layer composite adhesive fabric comprises the following steps: 1, component preparation: preparing components of two adhesives; 2, compounding: respectively compounding the two adhesives; 3, adhesive cement preparation: preparing adhesive cements of the two adhesives; 4, adhesive coating: coating the adhesive cement of a second adhesive on two faces of a nylon fabric, and then coating the adhesive cement of a first adhesive on one face of the nylon fabric; and 5, curing to obtain the multi-layer composite adhesive fabric. According to the formula of the process provided by the invention, the quality of the product is greatly improved; and the product is smooth and beautiful in surface, and has very good protection property against various corrosive substances.

Description

technical field [0001] The invention relates to a production process of an adhesive plaster, in particular to a production method of a multi-layer composite adhesive plaster. Background technique [0002] Traditionally, when producing multi-layer composite tapes, during vulcanization, due to the increase in heat energy and volume expansion of the low molecular volatiles and organic solvents in the inner rubber layer during the vulcanization process, when the internal pressure reaches a certain level, the outer layer of rubber will be broken. layer, resulting in serious air bubbles, pinholes, and spongy phenomena on the surface of the adhesive tape (such as figure 2 , 3 As shown), the resulting composite film is loose and rough, with extremely poor protective performance and no practical use value. Therefore need a kind of smooth surface without air bubbles, pinholes, composite adhesive tape with good protective performance. Contents of the invention [0003] The prese...
