Description

Technical Field

[0001] The present invention relates to the technical field of glue materials, and more particularly to a water-based environmentally friendly polymerization enhancer, a water-based environmentally friendly oxidized glue containing the same, and a preparation method and application thereof. Background Art

[0002] At present, the paper packaging products used for household appliances, precision electronic and mechanical products, food and medicine are mostly white cardboard boxes, corrugated paper, kraft paper boxes, etc., and are bonded by glue.

[0003] The glue currently available on the market has the following problems:

[0004] (1) The carton quick-drying bonding speed is slow;

[0005] (2) It is not suitable for long-distance transportation in a humid environment, which can easily cause the cartons to mold;

[0006] (3) A large amount of glue is required for bonding, which consumes a lot of production costs;

[0007] (4) The initial adhesion and penetration of the carton are poor, and the edges of the carton are easy to split before and after mounting;

[0008] (5) The raw material components contained in existing glues, such as active diluents, curing agents, etc., have varying degrees of toxicity and irritation.

[0009] Therefore, it is an urgent problem for technicians in this field to provide a low-cost, green and environmentally friendly polymerization enhancer that can enhance the adhesion and quick-drying properties of white cardboard boxes, corrugated paper, and kraft paperboard boxes, as well as glue and preparation methods containing the same. Summary of the invention

[0010] In view of this, in order to solve the problem in the prior art that white card boxes, corrugated paper, and kraft paper boxes are difficult to bond with glue, the present invention provides a water-based environmentally friendly polymerization enhancer, comprising a water-based environmentally friendly oxidized glue, which can increase the hardness, adhesion and penetration of color boxes, paper, and paper boxes.

[0011] In order to achieve the above object, the present invention adopts the following technical solution:

[0018] Preferably, the water-based environmentally friendly polymerization enhancer comprises the following components in parts by weight:

[0019] 8 parts of urea-formaldehyde resin powder, 28 parts of white dextrin powder, 8 parts of phenolic resin, 5 parts of Huanghu fine powder, 19 parts of talc, 5 parts of kaolin, 1 part of defoamer, 1 part of preservative, 1 part of desiccant, 3 parts of catalyst, 1 part of stabilizer, 3 parts of bentonite, 10 parts of oxidant, 5 parts of gypsum powder, and 2 parts of sodium diacetate.

[0020] A method for preparing a water-based environmentally friendly polymerization enhancer comprises the following steps:

[0021] Weigh each component according to the above weight parts;

[0022] Urea-formaldehyde resin powder, white dextrin powder, Huanghu fine powder, phenolic resin, talcum powder and kaolin are stirred in a mixing mixer. After stirring for 15 minutes, the remaining components are added and stirred for another 15 minutes to obtain a water-based environmentally friendly polymerization enhancer.

[0023] A water-based environmentally friendly oxidation adhesive comprises the water-based environmentally friendly polymerization enhancer.

[0024] Preferably, the water-based environmentally friendly oxidized glue comprises the following components in parts by weight:

[0025] 3-4 parts of water-based environmentally friendly polymerization enhancer, 210-230 parts of water, 45-50 parts of starch, 10-12 parts of flake caustic soda, and 5-7 parts of borax aqueous solution.

[0026] Preferably, the water-based environmentally friendly oxidized glue comprises the following components in parts by weight:

[0027] 3.8 parts of water-based environmentally friendly polymerization enhancer, 230 parts of water, 50 parts of starch, 12 parts of flake caustic soda, and 7 parts of borax aqueous solution.

[0028] A method for preparing a water-based environmentally friendly oxidized glue specifically comprises the following steps:

[0029] (1) mixing water, starch and the polymerization catalyst enhancer in accordance with the above weight proportions and stirring uniformly to obtain a mixed solution 1;

[0030] (2) adding caustic soda solution to the mixed solution 1 and stirring for 2 minutes to form a paste, and then allowing it to stand for auto-oxidation to obtain a mixed solution 2;

[0031] (3) Adding borax aqueous solution to the mixed solution 2 and stirring for 10 minutes to obtain the aqueous environmentally friendly oxidized glue.

[0032] The beneficial technical effect achieved by the above technical solution is: 3.8 weight parts of polymerization catalyst enhancer are added to each package of starch (50 weight parts) in the above-mentioned oxidized starch glue, and the prepared glue can increase the carton to dry quickly, have a strong bond, good flatness, and no mold, and can also enhance the penetration of the glue. Finally, the viscosity of the final prepared glue is measured with a 4-cup coating. If the glue is too thin, borax water can be added, and if the glue is too thick, water can be added. The viscosity range can be adjusted according to the needs of various manufacturers.

[0033] Preferably, the stirring time in step (1) is 5 minutes.

[0034] Preferably, the standing time in step (2) is: if it is summer, the standing time is 2 hours;

[0035] If it is winter, the standing time is 8 hours.

[0036] Preferably, the preparation process of the caustic soda flake solution in step (2) is specifically as follows: caustic soda flakes and water are mixed and stirred evenly to obtain the caustic soda flake solution, the mass fraction of which is 50%.

[0037] Preferably, the preparation process of the borax aqueous solution in step (3) is: mixing water and borax to obtain the borax aqueous solution, the mass fraction of which is 28.6%.

[0038] The beneficial technical effect achieved by the above technical solution is: because borax can cause cross-linking between starch molecules, the original linear structure is changed into a network structure, thus increasing the viscosity and improving the bonding performance. The role of borax in making carton glue: cross-linking can increase the linear chain length of starch and increase the viscosity of the glue.

[0039] Preferably, the viscosity of the glue is measured by using a 4-cup coating, which is 20 seconds for a high-speed machine at 12,000 rpm and 30 seconds for a low-speed machine at 5,000 rpm.

[0040] Preferably, the viscosity of the glue in step (3) is measured in 20-35 seconds after coating 4 cups.

[0041] The above water-based environmentally friendly oxidized adhesive is used in color box corrugated paper, paper mounting, roll gray board paper lamination, white cardboard mounting and bonding.

[0042] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a water-based environmentally friendly polymerization enhancer, a glue containing the same, and a preparation method and application thereof, which have the following technical effects:

[0043] 1. The water-based environmentally friendly oxidized glue powder glue prepared by the present invention can ensure good bonding strength and penetration under the premise of small dosage; and the front and back edges of the carton are not opened, and the hardness and flatness are good;

[0044] 2. The glue is odorless, non-toxic, moisture-proof, and more suitable for long-distance transportation in humid environments. The bonding position will not become moldy. It has good safety and environmental protection, and is a high-tech environmentally friendly glue.
