Problems solved by technology

[0004]Through the above-mentioned related technologies, although the moisture in the starch adhesive can effectively wet the corrugated paper, soften the paper fibers, and open the channel for the subsequent bonding process, but due to the penetration of the corrugated paper There is more moisture in the pores on the surface of the fiber, which easily leads to a higher water content in the corrugated paper and a slower drying speed of the adhesive

preparation example 1

[0048] Preparation example 1: a kind of modified tapioca starch, included concrete component and weight are as shown in table 2, comprise following preparation steps:

[0049] A1: Mix and stir tapioca starch and water, the stirring speed is 200r / min, after stirring evenly, add the nonionic surfactant fatty alcohol polyoxyethylene ether, mix and stir, the stirring speed is 200r / min, after stirring uniformly, obtain primary cassava starch;

[0050] A2: At a temperature of 75°C, mix and stir primary tapioca starch and acrylic resin at a stirring speed of 300r / min. After stirring evenly, add initiator and silane coupling agent, mix and stir evenly, and dry after 3 hours. After pulverizing, the modified tapioca starch is obtained.

preparation example 2

[0051] Preparation example 2: a kind of modified tapioca starch, and the difference of preparation example 1 is that included concrete component and weight are as shown in table 2, comprise following preparation steps:

[0052]A1: Mix and stir tapioca starch and water, the stirring speed is 200r / min, after stirring evenly, add the nonionic surfactant fatty alcohol polyoxyethylene ether, mix and stir, the stirring speed is 200r / min, after stirring uniformly, obtain primary cassava starch;

[0053] A2: At a temperature of 85°C, mix and stir the primary tapioca starch and polyacrylamide at a stirring speed of 300r / min. After stirring evenly, add the initiator and silane coupling agent. After mixing and stirring evenly, wait for 1 hour before drying After drying and crushing, the modified tapioca starch is obtained.

preparation example 3-4

[0054] Preparation example 3-4: a kind of modified tapioca starch, and the difference of preparation example 2 is that the weight of each component is different, and the concrete component that comprises and weight are as shown in table 2.

Abstract

The invention relates to the technical field of adhesives, and particularly discloses a corrugated paper compounding adhesive and a preparation method thereof. The corrugated paper compounding adhesive comprises the following raw materials in parts by weight: 250-350 parts of corn starch, 40-60 parts of modified cassava starch, 9-12 parts of sodium hydroxide, 1-3 parts of borax, 2-6 parts of bentonite, 6-10 parts of filler, 4-6 parts of a drier and 1000-1300 parts of water; and the drier is composed of sorbitol, sodium polyacrylate and polyvinyl alcohol, and the weight ratio of the sorbitol to the sodium polyacrylate to the polyvinyl alcohol is 1:(0.5-1):(1-2). The preparation method comprises the steps: heating 500-600 parts by weight of water to 35-50 DEG C, adding the corn starch and the modified cassava starch, mixing uniformly, adding the sodium hydroxide, and continuously mixing uniformly; adding the balance of water and borax after 60-80 minutes, and uniformly mixing to obtain a first mixture; and then adding the filler, the drier and the bentonite, and uniformly mixing to obtain the corrugated paper compounding adhesive. The corrugated paper compounding adhesive disclosed by the invention has the advantage of high drying speed.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive for compounding corrugated paper and a preparation method thereof. Background technique [0002] Glue for corrugated cardboard is an important adhesive in the production process of corrugated cardboard, mainly based on starch, which has the advantages of low price and wide sources. [0003] The publication number is CN101134881A, and the Chinese patent application published on March 05, 2008 discloses a starch adhesive for producing high-strength water-resistant corrugated cardboard, which is composed of the following raw materials in weight ratio: 50-90 parts of water; 20-40 parts of starch 0.5-3.5 parts of caustic soda; 0.1-0.2 parts of suspending agent; 0.25-0.3 parts of borax; 0.6-2.0 parts of bridging agent; the temperature of the water is 35-36°C. [0004] Through the above-mentioned related technologies, although the moisture in the starch adhesive can effec...
