Embodiment 1

[0030] A kind of method that cloth sticks adhesive back, it comprises the steps:

[0031] A. Preparation of hot melt adhesive diaphragm 4: Coat the first layer of adhesive liquid on the mold, then evenly sprinkle reinforcing filler 2 on the first layer of adhesive liquid, and raise the temperature to 60°C to solidify the first layer of adhesive liquid to form a matrix The film layer 1, then coat the second layer of adhesive liquid on the surface of the base film layer 1 and the reinforcing filler 2 and heat up to 60°C to solidify to form the reinforcing layer 3, and finally release the mold to obtain the hot-melt adhesive diaphragm 4;

[0032] B. Attach the reinforcing layer 3 of the hot melt adhesive diaphragm 4 prepared in step A to the cloth 5, then pressurize to 90MPa, pressurize for 0.75h, and raise the temperature to 180°C to melt the hot melt adhesive diaphragm 4, and finally Cooling and shaping, the temperature of cooling and shaping is 55°C, cooling for 1.1h, and a se...

Abstract

The invention relates to the technical field of cloth processing, in particular to a method for coating a backing adhesive on cloth. The method for coating the backing adhesive on the cloth comprisesthe following steps of A, preparing a hot melt adhesive film plate: coating a first layer of adhesive liquid on a mould, then uniformly scattering a reinforcing filler on the first layer of adhesive liquid, heating to cure the first layer of adhesive liquid so as to form a base film layer, then coating a second layer of adhesive liquid on the surfaces of the base film layer and the reinforcing filler, heating to cure so as to form a reinforcing layer, and finally demoulding to obtain the hot melt adhesive film plate; B, laminating the reinforcing layer of the hot melt adhesive film plate obtained in the step A and the cloth, then pressurizing and heating for melting the hot melt adhesive film plate, and finally cooling and sizing to obtain a semi-finished product; and C, laminating a polyester aluminized film and the semi-finished hot melt adhesive film plate obtained in the step B, then heating for melting the hot melt adhesive film plate, pressurizing, and cooling and sizing to obtain a finished product. The method for coating the backing adhesive on the cloth is simple to operate, high in production efficiency, environmental-friendly and safe; and the cloth laminated with the backing adhesive has high rigidity and high rebound resilience.

Description

technical field [0001] The invention relates to the technical field of cloth processing, in particular to a method for pasting cloth with adhesive. Background technique [0002] A layer of back glue is usually pasted on the fabric of boxes, bags, and bags to enhance the strength of the fabric and the degree of binding yarn. The existing method of sticking back adhesive includes three processes: 1. Cover the rolled cloth with a layer of adhesive to increase the viscosity; 3. Paste a layer of polyester coating on the semi-finished product pasted with PVC material. This method of sticking the back glue requires three processing procedures, and the production efficiency is low. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies existing in the prior art, the object of the present invention is to provide a method for pasting adhesive on cloth, which is simple in operation, high in production efficiency, environmentally friendly and safe,...
