Problems solved by technology

[0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. At present, most domestic manufacturers use starch as the raw material for surface sizing in order to produce high-quality high-strength corrugated paper. High-quality starch can effectively enhance the strength of corrugated paper, but because starch is widely used, resources are in short supply and expensive, a large amount of starch used in the production of corrugated paper is easy to not only cause resource shortages, but also increase the production cost of high-strength corrugated paper

Embodiment 1

[0015] A kind of starch enhancer for corrugated paper manufacturing, its raw material component weight ratio is: 35 parts of sodium chlorite, 25 parts of trichlorobenzoyl chloride, 30 parts of thionyl chloride, 5 parts of ethanol, dicyclohexyl carbon 3 parts of diimine, 1.2 parts of 4-dimethylaminopyridine, and 0.8 parts of ammonium persulfate.

[0016] Add the raw materials in proportion to the mixer, heat up to 40-60°C, stir for 20-40 minutes, and cool down naturally to obtain the finished product.

[0017] The resulting finished product is added when gelatinizing the surface with glued starch, stirred evenly, heated up to 90-100°C, heat-preserved and gelatinized for 15-20 minutes, and can be used after passing in cold air to cool down.

[0018] The flute type is E-flute corrugated paper, and the addition amount of starch enhancer is 2%.

Embodiment 2

[0020] A starch enhancer for corrugated paper production, the weight ratio of its raw material components is: 45 parts of sodium chlorite, 15 parts of trichlorobenzoyl chloride, 30 parts of thionyl chloride, 6 parts of ethanol, dicyclohexyl carbon 2.4 parts of diimine, 1 part of 4-dimethylaminopyridine, and 0.6 parts of sodium persulfate.

[0021] Add the raw materials in proportion to the mixer, heat up to 40-60°C, stir for 20-40 minutes, and cool down naturally to obtain the finished product.

[0022] The resulting finished product is added when gelatinizing the surface with glued starch, stirred evenly, heated up to 90-100°C, heat-preserved and gelatinized for 15-20 minutes, and can be used after passing in cold air to cool down.

[0023] The flute type is C flute corrugated paper, and the addition amount of starch enhancer is 6%.

Embodiment 3

[0025] A starch enhancer for corrugated paper production, the weight ratio of raw material components is: 55 parts of sodium chlorite, 15 parts of trichlorobenzoyl chloride, 20 parts of thionyl chloride, 6 parts of methanol, dicyclohexyl carbon 2.8 parts of diimine, 0.8 parts of 4-dimethylaminopyridine, and 0.4 parts of initiator.

[0026] Add the raw materials in proportion to the mixer, heat up to 40-60°C, stir for 20-40 minutes, and cool down naturally to obtain the finished product.

[0027] The resulting finished product is added when gelatinizing the surface with glued starch, stirred evenly, heated up to 90-100°C, heat-preserved and gelatinized for 15-20 minutes, and can be used after passing in cold air to cool down.

[0028] The flute type is B flute corrugated paper, and the addition amount of starch enhancer is 4%.

Abstract

The present invention discloses a starch reinforcing agent for production of a corrugated board. The reinforcing agent comprises the following raw materials: sodium chlorite, trichlorobenzene chloride, sulphone chloride, ethanol, dicyclohexylcarbon-diimide, 4-dimethylaminopyridine and an initiator. Compared to the prior art, the starch reinforcing agent disclosed by the present invention has the following advantages that the starch reinforcing agent is combined with an aldehyde group and a hydroxy group in starch to form a ligand, so that the cohesion, the stability and the waterproof capability of the starch are enhanced, and the reaction condition is simple, the time is short, the yield is high, and the dosage of the starch can be effectively reduced, the production cost is saved, and the water resistance is improved.
