s4: then the base fabric is spliced on the lower surface of the white glue through a vulcanizing machine to form three-cloth two-glue, and then the upper surface of the surface cloth is coated with uniform surface glue so as to press the upper surface of the surface cloth with surface glue to form three-cloth three-glue;
s5: then the surface rubber on the upper surface of the face fabric is vulcanized, and then the surface of the surface rubber is polished by a polisher.
6. A process of stripping a glazing cloth as claimed in claim 5, wherein: the vulcanizing machine is a machine for vulcanizing various rubber and plastic products, the vulcanizing machine vulcanizes the black rubber coated on the surface of the middle cloth, and a space three-dimensional structure is formed in the vulcanized black rubber, so that the vulcanized black rubber has high elasticity, heat resistance and tensile strength.
7. A process of releasing a glazing cloth as claimed in claim 5, wherein: according to the foaming technology, a honeycomb or porous structure is formed by the black adhesive layer through the addition and reaction of a chemical foaming agent, and the foaming adhesive enters the cloth seam depth in the foaming process, so that the shell fabric can be easily peeled.
8. A process of releasing a glazing cloth as claimed in claim 5, wherein: the process of vulcanizing the surface glue is to add sulfur powder into the surface glue to convert linear macromolecules of the surface glue into a three-dimensional reticular structure.
9. A process of stripping a glazing cloth as claimed in claim 5, wherein: the temperature of the surface rubber during vulcanization processing is 130-170 ℃, the time of vulcanization processing is 1-0.4h, and the pressure during vulcanization processing is 16-8Mpa.
