Problems solved by technology

This method needs to refit the production line equipment. The manually controlled spray device is not fine enough, which will increase the labor load of the workers and distract the workers from their own work. The automatic spray device linked with the production pipe system has a complicated structure. large investment

Embodiment 1

[0017] The preparation method of the adhesive with explosion-proof line function for the production of corrugated cardboard of this embodiment comprises the following steps:

[0018] Step 1: Add 200 kg of water into the cooked pulp tank, stir and slowly add 20 kg of cornstarch and 5 kg of sodium hydroxide in sequence, and stir for 12 minutes until the slurry is beige and transparent, and the cooked pulp is obtained;

[0019] Step 2: Add 800kg of water into the raw slurry tank, stir and slowly add 270kg of cornstarch, 2kg of borax in turn, stir for 5 minutes, then add 7kg of stabilizer, 2kg of enhancer, 1kg of sodium chloride in turn, and stir for 3 minutes;

[0020] Step 3: slowly pour the cooked pulp prepared in step 1 into the raw pulp tank in step 2, and stir for 20 minutes to obtain the adhesive with the function of explosion-proof wire.

Embodiment 2

[0022] The preparation method of the adhesive with explosion-proof line function for the production of corrugated cardboard of this embodiment comprises the following steps:

[0023] Step 1: Add 200 kg of water into the cooked pulp tank, stir and slowly add 25 kg of cornstarch and 7.5 kg of sodium hydroxide in sequence, and stir for 15 minutes until the slurry is beige and transparent, and the cooked pulp is obtained;

[0024] Step 2: Add 800kg of water into the raw slurry tank, stir and slowly add 350kg of cornstarch, 3kg of borax in turn, stir for 5 minutes, then add 9kg of stabilizer, 3kg of enhancer, 2kg of sodium chloride in turn, and stir for 3 minutes;

[0025] Step 3: slowly pour the cooked pulp prepared in step 1 into the raw pulp tank in step 2, and stir for 20 minutes to obtain the adhesive with the function of explosion-proof wire.

Embodiment 3

[0027] The preparation method of the adhesive with explosion-proof line function for the production of corrugated cardboard of this embodiment comprises the following steps:

[0028] Step 1: Add 200 kg of water into the cooked pulp tank, stir and slowly add 30 kg of cornstarch and 10 kg of sodium hydroxide in sequence, and stir for 18 minutes until the slurry is beige and transparent, and the cooked pulp is obtained;

[0029] Step 2: Add 800kg of water into the raw slurry tank, stir and slowly add 380kg of cornstarch, 4kg of borax in turn, stir for 5 minutes, then add 8kg of stabilizer, 2.5kg of enhancer, 3kg of sodium chloride in turn, and stir for 3 minutes;

[0030] Step 3: slowly pour the cooked pulp prepared in step 1 into the raw pulp tank in step 2, and stir for 20 minutes to obtain the adhesive with the function of explosion-proof wire.

Abstract

The invention discloses an adhesive with an anti-line-explosion function for corrugated paperboard production and a preparation method of the adhesive. The adhesive comprises the following components in parts by weight: 1,000 parts of water, 300-400 parts of corn starch, 5-10 parts of sodium hydroxide, 2-4 parts of borax, 7-9 parts of a stabilizer, 2-3 parts of a reinforcing agent and 1-3 parts of sodium chloride. The preparation method adopts a two-step method. Due to the use of the adhesive, the problem of line explosion and breakage of paperboards in a dry climate is effectively solved without adding a spraying system, the production cost of the paperboards is scarcely increased, and the paperboard uniformity is improved.

Description

technical field [0001] The invention belongs to the technical field of corrugated cardboard production, and in particular relates to an adhesive with explosion-proof thread function for corrugated cardboard production and a preparation method thereof. Background technique [0002] The moisture content of corrugated cardboard is one of the important indicators of corrugated cardboard, which directly determines the performance of corrugated cardboard and cartons. Corrugated cardboard is made of highly water-absorbent fiber base paper, which is greatly affected by environmental humidity. Therefore, the biggest technical problem in corrugated cardboard packaging is that it is difficult to resist water and keep moisture. During transportation and storage, the environment with high humidity will absorb moisture and reduce the strength; while in a dry environment, the moisture in corrugated cardboard will evaporate, and when the moisture drops to a certain level, it will become bri...
