preparation example Construction

[0028] The present invention also provides a kind of preparation method of described adhesive composition, comprising:

[0029] The polyurethane binder and the polyvinyl acetate binder are mixed according to the ratio, and stirred evenly to obtain a binder composition.

[0030] According to the present invention, since the polyurethane adhesive is preferably Henkel 369 # glue. For polyurethanes, the polyvinyl acetate binder is preferably polyvinyl acetate emulsion type III glue, both of which are water-based binders, so they can be blended. But since the Henkel 369 # The viscosity of the glue is greater than the polyvinyl acetate emulsion type III glue, so special methods need to be used when stirring. According to the present invention, the stirring is specifically:

[0031] The mixture of the polyurethane binder and the polyvinyl acetate binder is placed in the first stirrer and stirred for 10 to 20 minutes to obtain the first mixed solution;

[0032] Put the first mixed...

Embodiment 1

[0036] Will Henkel 369 # 15 kilograms of glue and 15 kilograms of polyvinyl acetate emulsion type III glue produced by Haiyan Latex Factory are placed in a large glue barrel of 50 kilograms, and stirred with electric stirring for 10 minutes to obtain the first mixed solution; then pour the first mixed solution Put it into another glue bucket so that the upper and lower layers of glue can be fully blended, and then stir for 10 minutes before use.

Embodiment 2

[0038] Will Henkel 369 # 18 kilograms of glue and 20 kilograms of polyvinyl acetate emulsion type III glue produced by Haiyan Latex Factory are placed in a 50-kg large rubber bucket, and stirred with electric stirring for 10 minutes to obtain the first mixed solution; then pour the first mixed solution Put it into another glue bucket so that the upper and lower layers of glue can be fully blended, and then stir for 10 minutes before use.

Abstract

The invention provides an adhesive composite which comprises the following components in parts by volume: 15-25 parts of polyurethane adhesives and 15-30 parts of polyvinyl acetate adhesives. The invention also provides a preparation method of the adhesive composite. The preparation method comprises the following steps of: mixing the polyurethane adhesives and the polyvinyl acetate adhesives in proportion; uniformly stirring to obtain the adhesive composite. The adhesive composite provided by the invention is convenient to brush and fast dried completely, can not be adhered back after being separated and is favorable to post-procedure operation. The preparation method of the adhesive composite, which is provided by the invention, can be used for preparing the adhesive composite which has good property and is suitable for a multipage adhering publication by using least procedures, can not cause the difficulty for subsequent production in the preparation process of a small calendar and a note pad especially, reduces the production cost and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive composition and a preparation method thereof. Background technique [0002] The adhesive used for the detachable small calendar or memo is generally made of adhesive with better viscosity. At present, the most widely used is polyurethane adhesive, especially Henkel 369 # Glue is most commonly used. It is characterized by good viscosity, not easy to dry out, elastic, and stretchable, etc., but after drying, the parts will stick back when stacked together, resulting in the need to re-partition, and in the process of re-partition, it is easy to cause damage to the product There is a page-off phenomenon, which does not meet the quality requirements, and increases the loss rate and rework rate, which is not conducive to operation and also affects production progress. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an...
