Abstract

The invention discloses a papermaking auxiliary agent mixture. The papermaking auxiliary agent mixture is prepared from the following raw materials in parts by mass: 12-20 parts of carboxymethyl cellulose, 14-20 parts of mica powder, 20-30 parts of pot clay, 2-5 parts of polyethylene glycol, 1-4 parts of polyethylene wax, 1-3 parts of propanediol butyl ether, 2-4 parts of polyoxyethylene nonyl phenyl ether, 2-5 parts of polyoxyethylene polyoxypropylene pentaerythritol ether, 1-2 parts of nipagin ester, 2-5 parts of white wax, 1.2-2 parts of azodicarbonamide, 1-4 parts of sodium triphosphate and 2-4 parts of lactitol. With the adoption of the product disclosed by the invention, a fiber structure of paper pulp can be improved and the use amount of the raw materials of the paper pulp is reduced; and the mechanical strength of paper is improved, the cost is reduced and the pollution to the environment is not caused.

Description

technical field [0001] The invention relates to the field of papermaking auxiliary agents, in particular to a papermaking auxiliary agent mixture and a preparation method. Background technique [0002] With the improvement of people's living standards, the requirements for paper are getting higher and higher. Paper is a flaky fiber product used for writing, printing, painting or packaging. Paper is used for exchanging ideas, spreading culture, developing science and technology and production. It is a powerful tool and material. However, paper has its shortcomings, such as low strength, easy to mold, etc., and it is difficult to store for a long time. Although the existing papermaking technology is relatively mature, due to the complicated preparation process, the lack of coniferous wood resources and the requirements for environmental protection, these complex factors put forward new requirements for papermaking additives. [0003] The Chinese patent document of applicatio...
