Papermaking auxiliary agent based on non-wood fibers and preparation method of papermaking auxiliary agent

Abstract

The invention discloses a papermaking auxiliary agent based on non-wood fibers. A formula of the papermaking auxiliary agent based on the non-wood fibers comprises the components in parts by mass: 100-200 parts of a filler, 15-35 parts of a retention filter aid, 10-20 parts of oxalic acid, 8-15 parts of alkyl sulfonic acid, 5-8 parts of alkylphenol polyoxyethylene ether sodium sulfonate, 1-3 partsof isooctyl polyoxyethylene ether, 10-20 parts of acrylamide, 15-25 parts of an emulsifier, 8-25 parts of a thickener and 10-30 parts of metal peroxide. According to the invention, one or a mixture of more of carboxymethyl cellulose, nano silicon dioxide and borax is used as a filler composition, the formula is scientific, the preparation method is simple, the obtained product can make the uniformity of pulp better, the fiber structure of paper pulp can be improved, the paper is prevented from falling and fluffing in the use process, and the quality of the paper is improved; the dissociationof fibers is facilitated, so that the pulping is facilitated, the efficiency ratio is improved, the environmental influence of dissolved substances on process water is reduced, and thus the yield is improved.

Description

technical field [0001] The invention belongs to the technical field of papermaking auxiliaries, in particular to a non-wood fiber-based papermaking auxiliaries; in particular, it also relates to a preparation method of the non-wood fiber-based papermaking auxiliaries. Background technique [0002] Papermaking auxiliaries are auxiliary chemicals added in the pulp and papermaking process to impart certain properties to the process and products. [0003] The existing commonly used papermaking cooking methods include caustic soda method, sulfate method, alkaline, neutral, sodium sulfite method, etc. Among them, sulfate method cooking is widely used because of its high pulp strength, but sulfate method Pulping has the disadvantages of serious equipment corrosion, heavy environmental pollution, difficult pulp bleaching, and high pulping cost. During the cooking process of pulp, in order to accelerate the de-lignification rate and protect cellulose and hemicellulose from Degradati...
