Abstract

The invention discloses a papermaking auxiliary agent composition. The papermaking auxiliary agent composition is prepared from the following raw materials in parts by weight: 12-20 parts of hemicellulose, 20-30 parts of nano titanium dioxide, 10-14 parts of zeolite, 3-8 parts of polyethylene glycol, 1-5 parts of magnesium stearate, 2-6 parts of chlorinated paraffin, 1-3 parts of polyoxyethylene nonyl phenyl ether, 2-3 parts of higher alcohol fatty acid ester complex, 1-2 parts of hydroquinone, 2-5 parts of microcrystalline wax, 1-2 parts of carbonyl diamide, 1-4 parts of sodium dihydrogen phosphate and 1-5 parts of mannitol. The papermaking auxiliary agent composition disclosed by the invention also has the good effects that the prepared papermaking auxiliary agent composition has a good retention effect and the tensile strength of paper sheets can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a papermaking auxiliary composition. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading newspapers, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. Paper is a flaky fiber product used for writing, printing, painting or packaging. Paper is a powerful tool and material in the exchange of ideas, dissemination of culture, development of science and technology and production. [0003] Papermaking is generally made of water suspensions of plant fibers that have been pulped, staggered on the net, dehydrated initially, and then compressed and dried. Although the existing papermaking technology is relatively mature, its process is still very complicated, requiring multiple processes and adding various additives in...
