Method for manufacturing hot melt adhesive

Abstract

The invention relates to a method for manufacturing a hot melt adhesive. The method comprises the following steps: dissolving raw materials, scheduling the adhesive, carrying out extrusion molding and anti-adhesion processing, cooling, drying and packaging; wherein when the anti-adhesion processing is carried out, an extrusion hot melt adhesive is imported into an anti-adhesion solution which comprises water and a mold release which forms an anti-adhesion surface layer on the surface of the extrusion hot melt adhesive. According to the invention, water and the mold release are mixed with stirring according to a proper proportion, the mold release can form the anti-adhesion surface layer on the surface of the hot melt adhesive in technical use, and the mold release is adopted, so the anti-adhesion of the molded hot melt adhesive is improved, and the production efficiency of downstream users is improved; simultaneously the anti-adhesion processing is designed in a manner that the anti-adhesion processing and the cooling process in an original technology are synchronously carried out, so no extra technical steps appear, the technical time is not increased, and the output of the hot melt adhesive is not influenced; and in addition, properties of the hot melt adhesive can reach requirements of the downstream users through cooperating the improvement of the formula of the hot melt adhesive, and products have good economic benefit.

Description

technical field [0001] The present invention relates to a method for manufacturing hot-melt adhesives to prevent mutual sticking (Anti Blocking) when hot-melt adhesives are packaged, in particular to a method of adding an adaptive formula in the process and cooperating with the production process to make the surface of the hot-melt adhesives form a An anti-sticking surface layer, a method for manufacturing a hot-melt adhesive that improves the stickiness of the hot-melt adhesive after packaging. Background technique [0002] Granular hot melt adhesive has small contact area, beautiful appearance, easy feeding, fast melting, and high efficiency for the production and use of downstream products. Therefore, most hot melt adhesive manufacturers generally produce granular hot melt adhesive. [0003] However, because most of the hot melt adhesive formulas have the characteristics of easy sticking, the finished products are often due to the easy sticking properties of the formula, ...
