Abstract

The invention belongs to the technical field of adhesive preparation, and discloses a water-based adhesive suitable for surface bonding of paper packaging and a preparation method of the water-based adhesive. The water-based adhesive for the paper packaging is prepared from the following components in parts by weight: 9-18 parts of polyvinyl acetate, 20-26 parts of butyl acrylate, 3.0-5.5 parts of octadecyl methacrylate, 1-3 parts of ammonium persulfate, 3-6 parts of soya fatty acid, 0.8-1.5 parts of sodium dihydrogen phosphate, 1.5-3.0 parts of dicumyl peroxide, 1.5-1.8 parts of polyamide, 3-5 parts of carboxymethylcellulose, 0.2-0.5 part of a silicon ether defoamer and the balance of water, wherein the sum of parts by weight of all the components is 100 parts. The water-based adhesive for the paper packaging has the advantages of being excellent in performance in the aspect of bonding of carton boxes and similar products, low in cost, non-combustible, water-based, environmentally-friendly, and the like, and is high in bonding strength and rapid in curing speed, thus meeting the demands of an automatic bonding process.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to a water-based adhesive suitable for the automatic bonding process of paper product packaging boxes and a preparation method thereof. Background technique [0002] Automatic carton gluing is an automatic processing technology that has developed rapidly in recent years. It has the advantages of fast speed, good bonding effect and high efficiency. Due to the fast operation speed, it is required that the adhesive used should be able to achieve the effect of fast drying and sticking. However, the current adhesives either cannot cure faster, or use volatile solvents to increase the drying speed. The current pure water-based solvent-free adhesives cannot meet the requirements of use well. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies of the prior art, the primary purpose of the present invention is to provide a wat...
