Abstract

The invention discloses a papermaking cooking reagent, which is mainly prepared from the following raw materials by weight: 20-28 parts of methacrylic acid, 5-9 parts of dioctadecyl dimethyl ammonium chloride, 2-5 parts of an emulsifier, 1-3 parts of sodium hexametaphosphate, 1-2 parts of carboxymethyl cellulose, 0.5-3 parts of a defoaming agent, 3-6 parts of citric acid, 5-8 parts of sodium citrate, and 0.1-0.5 part of a light stabilizer. The papermaking cooking reagent provided by the invention can speed up the soaking and permeation of a cooking liquor to raw materials, and can reduce the alkali use dosage, as well as improve and protect the fiber strength. The cooked slurry is soft and loose, and has good elasticity. And the papermaking cooking reagent can prevent wrinkling of the finally prepared paper.

Description

[0001] technical field [0002] The invention relates to a cooking agent for papermaking. Background technique [0003] 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 can be added in alkaline method and acid method, especially in alkaline method pulping. It can accelerate 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 amount is preferably 0.02% to 0.05%. [0004] Although effective, these current cooking agents contain substances that are polluting to the environment and wrinkle the final paper. Contents of the invention [0005] Purpose of the invention: in order to overcome the...
