Embodiment 1

[0011] A cooking agent for papermaking, mainly made of the following raw materials in parts by weight: 20 parts of methacrylic acid, 5 parts of dioctadecyldimethyl ammonium chloride, 2 parts of emulsifier, 1 part of sodium hexametaphosphate, 1 part of hydroxymethyl cellulose, 0.5 part of defoamer, 3 parts of citric acid, 5 parts of sodium citrate, 0.1 part of light stabilizer.

[0012] In the present invention, the emulsifier is sodium dodecylbenzenesulfonate.

Embodiment 2

[0013] Embodiment 2: a kind of cooking agent for papermaking, mainly made of the raw material of following parts by weight: 28 parts of methacrylic acid, 9 parts of dioctadecyl dimethyl ammonium chloride, 5 parts of emulsifier, hexametaphosphoric acid 3 parts of sodium, 2 parts of hydroxymethyl cellulose, 3 parts of defoamer, 6 parts of citric acid, 8 parts of sodium citrate, 0.5 part of light stabilizer, and 0.5 part of penetrant.

[0014] In the present invention, the emulsifier is op-7.

Embodiment 3

[0016] A cooking agent for papermaking, mainly made of the following raw materials in parts by weight: 20-28 parts of methacrylic acid, 5-9 parts of dioctadecyldimethyl ammonium chloride, 2-5 parts of emulsifier, six 1-3 parts of sodium metaphosphate, 1-2 parts of hydroxymethyl cellulose, 0.5-3 parts of defoamer, 3-6 parts of citric acid, 5-8 parts of sodium citrate, 0.1-0.5 parts of light stabilizer, penetration Dose 0.2-0.5 part.

Abstract

The invention discloses a cooking agent for papermaking, which is mainly made of the following raw materials in parts by weight: 20-28 parts of methacrylic acid, 5-9 parts of dioctadecyldimethylammonium chloride, 2-2 parts of emulsifier 5 parts, 1-3 parts of sodium hexametaphosphate, 1-2 parts of hydroxymethyl cellulose, 0.5-3 parts of defoamer, 3-6 parts of citric acid, 5-8 parts of sodium citrate, 0.1-0 parts of light stabilizer 0.5 servings. The advantages of the present invention are: the present invention can speed up the soaking and permeation of the raw materials by the cooking liquid, and can reduce the use of alkali, improve and protect the fiber strength, and the decocted pulp is soft and loose, and the pulp has good elasticity and can Prevents wrinkling of the final paper.

Description

technical field [0001] The invention relates to a cooking agent for papermaking. Background technique [0002] Papermaking cooking agent is a chemical that can assist cooking agent to improve cooking efficiency in the process of pulp making. There are mainly anthraquinone, dihydrodihydroxyanthracene disodium salt, quinone, etc. Adding anthraquinone and dihydrodihydroxyanthracene disodium salt in alkali method and acid method can be especially effective in alkali method pulping. It can speed up the delignification speed, shorten the cooking time, fast pulping speed, low energy consumption, small amount of alkali and bleaching chemicals, high fiber yield, and reduce waste liquid load. Its addition dosage is preferably 0.02%~0.05%, although the effect is very good, but these present cooking agents contain substances that pollute the environment, and make the final paper crumpled. Contents of the invention [0003] Purpose of the invention: in order to overcome the deficien...
