Embodiment 1

[0026] First, heat 60 parts of deionized water to 60°C, then add 80 parts of bisaminophenol epoxy resin and 2 parts of hydroxymethylcellulose into the deionized water in turn, stir evenly to form a solution, and then heat the solution to 100°C , add 5 parts of catalyst, 10 parts of sodium carbonate and 5 parts of bentonite successively therein, after stirring evenly, cool down to room temperature to obtain carton adhesive.

Embodiment 2

[0028] First, heat 80 parts of deionized water to 50°C, then add 100 parts of butadiene diepoxy resin and 1 part of hydroxymethyl cellulose into the deionized water in sequence, stir evenly to form a solution, and then heat the solution to 80 ℃, 3 parts of catalyst, 5 parts of sodium carbonate and 10 parts of bentonite were sequentially added thereto, stirred evenly, and cooled to room temperature to obtain a carton adhesive.

Embodiment 3

[0031] The particle diameters of each component in the above-mentioned Examples 1-3 all pass through a 250 mesh sieve.

[0032] And after the carton adhesives prepared in the above-mentioned Examples 1-3 are tested, their viscosities are respectively 360mPa·s, 320mPa·s and 336mPa·s, and the storage stability is > 6 months, and the holding force is > 24h, 180°peel strength: >4.8N / cm.

Abstract

The invention discloses a paper box binding agent which is characterized by comprising the following components in parts by weight: 80-100 parts of an adhesive, 3-5 parts of a catalyst, 1-3 parts of carboxy methylated cellulose (CMC), 5-10 parts of sodium carbonate, 5-10 parts of bentonite and 60-80 parts of deionized water; the invention further discloses the preparation method of the paper box binding agent. According to the paper box binding agent and the preparation method thereof, provided by the invention, the formula of the paper box binding agent is optimized, a reasonable content range is determined, therefore the finally prepared paper box binding agent is endowed with the advantages of high stability, high cohesive strength, high peel strength and adhesive power endurance, and besides, the preparation method is simple and easy to operate, improves the production efficiency and expands the application range of products.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a carton adhesive and a preparation method thereof, and belongs to the technical field of papermaking auxiliary agents. Background technique [0002] At present, cartons are widely used in the field of packaging due to their advantages of light weight, easy folding, and environmental protection. In the process of using cartons for packaging, adhesives are needed for bonding and fixing. , adhesion, peel strength and other aspects are not satisfactory. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a carton adhesive with high adhesive strength and peel strength and a preparation method thereof. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A carton adhesive is characterized in that it comprises the fol...
