Problems solved by technology

[0002] As one of the commonly used adhesives for corrugated paper, starch glue is not only low in cost but also easy to degrade and easy to process. However, with the increasing development of logistics today, the application of packaging boxes and boxes made of corrugated paper is also increasing. Widely used, it has gradually expanded from the early electrical package to today's fresh fruit, vegetable and fish packaging, while the traditional corrugated paper glue is usually prone to corrosion and degumming due to moisture, and it is easy to be glued after being exposed to sunlight outdoors. The problem of volatilization of glue additives to the inside of the box or box

Embodiment 1

[0023] A preparation method of corrugated paper glue, it may further comprise the steps:

[0024] (1) Add 75 parts of cornstarch to the mixer for stirring at 35°C. During the stirring process, gradually add 75 parts of pure water to make the starch paste, and then add 2 parts of sodium hydroxide, And continue stirring for 5 minutes to form material A, wherein the starch is pretreated by ultraviolet light irradiation for 20 minutes;

[0025] (2) Mix 7 parts of acrylic acid amide and 7 parts of polyvinyl alcohol uniformly to form material B;

[0026] (3) Add material B to material A, keep stirring during the adding process, then increase the temperature of the stirring environment to 45°C, and then add 2 parts of sodium benzoate, 0.5 parts of sodium carboxymethyl cellulose, and 0.5 parts of poly Siloxane, 0.2 parts of dibutyltin di(isooctyl mercaptoacetate), 2 parts of styrene-butadiene and 15 parts of purified water were continuously stirred for 15 minutes to form material C; ...

Embodiment 2

[0030] A preparation method of corrugated paper glue, it may further comprise the steps:

[0031] (1) Add 80 parts of cornstarch to the mixer at 40°C for stirring. During the stirring process, gradually add 80 parts of pure water to make the starch paste, and then add 3 parts of sodium hydroxide, And continue stirring for 7 minutes to form material A, wherein the starch is pretreated by ultraviolet light irradiation for 25 minutes;

[0032] (2) Mix 5 parts of acrylic acid amide and 5 parts of polyvinyl alcohol uniformly to form material B;

[0033] (3) Add material B to material A, keep stirring during the adding process, then increase the temperature of the stirring environment to 50°C, and then add 2.5 parts of sodium benzoate, 0.7 parts of sodium carboxymethyl cellulose, and 0.6 parts of poly Siloxane, 0.4 parts of dibutyltin di(isooctyl mercaptoacetate), 1 part of styrene-butadiene and 20 parts of purified water were stirred continuously for 18 minutes to form material C;...

Embodiment 3

[0037] A preparation method of corrugated paper glue, it may further comprise the steps:

[0038] (1) Add 85 parts of glutinous rice starch to the mixer for stirring at 45°C. During the stirring process, gradually add 85 parts of pure water to make the starch paste, and then add 5 parts of sodium hydroxide, And continue stirring for 10 minutes to form material A, wherein the starch is also pretreated by ultraviolet light irradiation for 30 minutes;

[0039] (2) Mix 10 parts of acrylic acid amide and 10 parts of polyvinyl alcohol evenly to form material B;

[0040] (3) Add material B to material A, keep stirring during the adding process, then increase the temperature of the stirring environment to 55°C, then add 3 parts of sodium benzoate, 1 part of sodium carboxymethyl cellulose, and 0.8 parts of polystyrene Siloxane, 0.7 parts of dibutyltin bis(isooctylmercaptoacetate), 3 parts of styrene-butadiene and 40 parts of purified water are continuously stirred for 15 to 20 minutes...

Abstract

The invention discloses corrugated paper glue water as well as a preparation method and application thereof. Starch and sodium hydroxide are mixed to form starch gel; then, polyacrylamide and polyvinyl alcohol are mixed to form the other gel; next, the other gel is mixed with the starch gel; sodium benzoate is added to be used as preservatives; sodium carboxymethylcellulose is used as dispersing agents; the system leveling effect is improved; polysiloxane is used as an antifoaming agent; di(iso-octyl mercaptoacetic acid) dibutyl tin is used as a stabilizing agent for mixing reaction; then, chitosan is added to be used as antibacterial agents; borax is added for promoting the system to be further formed into a gel system. By using the scheme, the bonding intensity of the corrugated paper glue water is great; the second sticking performance is good; when the bonded corrugated paper is used as package for transporting food or other fresh food and fruit and vegetables, a layer of thin filmUV glue layer is exerted between the inner paper layer and the core layer, so that good air environment can be maintained inside the prepared corrugated case; the freshness degree of contained articles is improved; the pollution is avoided.
