Problems solved by technology

[0004] However, in actual production and in the prior art, it is difficult to take into account the low amount of biological enzymes and the rapid penetration of pulping.
Although the importance of fast penetrating agents is also recognized in the prior art, due to the complex interaction relationship between the components in the compound composition, or because the compounding process is different, the strength of this interaction will also be caused , and even the mode of action will change, so this problem has not been solved well

Abstract

The invention discloses a rapid penetrant for bioenzyme pulping, which is prepared from the following components in parts by weight: 1.0 to 20.0 parts of dimethylformamide; 12.0 to 25.0 parts of penetrant BS; 0.5 to 10.0 parts of fatty alcohol polyoxyethylene ether; 1.0 to 10.0 parts of sodium dodecyl sulfonate; 15 to 18 parts of sodium diethylhexyl sulfosuccinate (rapid penetrant T); 1.0 to 3.0 parts of sodium diisobutylnaphthalene sulphonate (penetrant BX); 3 to 5 parts of dimethyl sulfoxide; 1.0 to 10.0 parts of N,N-dimethylacetamide; 1.0 to 5.0 parts of sulfamic acid; and 25.0 to 50.0 parts of water. Moreover, the invention discloses a preparation method for the penetrant. According to the rapid penetrant prepared by the method, the dosage of bioenzyme among pulping materials is less in the process of penetration, and rapid penetration for pulping is well-balanced.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a biological enzyme pulping rapid penetration agent and a preparation method thereof. Background technique [0002] Rapid penetrating agent is an important pulping and papermaking additive. Its molecule usually has two kinds of hydrophilic and lipophilic groups, which can form an adsorption layer at the interface of water and oil to connect the two, thus playing the role of emulsification and penetration. Adding an appropriate amount of bio-enzyme pulping fast penetrating agent in the production process of bio-pulping can fully emulsify the ingredients, mix evenly, prevent the segregation of bio-aids, increase the whiteness of the product material, improve the strength of the product, and improve the difficulty of pulping To a certain extent, it can soften and refine the effect, improve the product quality, and reduce the cost of the product at the same time.
