Abstract

The invention provides a preparation method and preparation system of an adhesive. The preparation method comprises the following steps of: adding polyvinyl alcohol and water into a reaction kettle to form a polyvinyl alcohol solution, cooling to 50-70 DEG C, adding polyvinyl alcohol, a monomer, a VAE emulsion, an emulsifier, an initiator and a plasticizer, and carrying out condensation polymerization; adding a certain amount of sodium acetate and sodium bicarbonate, and cooling to room temperature; conveying a cooled adhesive to an adhesive storage box through a conveying pipe, and conveying the cooled adhesive to an adhesive filling head through the adhesive storage box for adhesive filling, and after completing adhesive filling, making a rotary disc of an adhesive filling machine drive an adhesive pipe to walk by one station; and driving a bending assembly by a power air cylinder to bend the pipe opening of an adhesive pipe, and flattening the bent pipe opening in the vertical direction through a flattening mechanism. The preparation method and preparation system have the advantages of reasonable structure, high efficiency, and good using effect.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive preparation method and a preparation system thereof. Background technique [0002] Adhesive is one of the most important auxiliary materials. It is widely used in all walks of life. Adhesive is a viscous substance that connects two separated materials with its viscous ability. There are many types of adhesives. . After the traditional adhesive is poured into the rubber tube, the rubber tube is flattened by two-way clamps, which is slow and inefficient. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a preparation method and a preparation system of an adhesive with reasonable structure, high efficiency and good application effect. [0004] In order to achieve the above object, the technical solution provided by the present invention is: a preparation method of an adhesive and a p...
