Papermaking auxiliary agent mixture

Abstract

The invention discloses a papermaking auxiliary agent mixture. The papermaking auxiliary agent mixture is composed of following raw materials, by mass, 100 to 200 parts of terphenyl quinone, 100 to 200 parts of isopentene naphthoquinone, 100 to 200 parts of anthranol, 100 to 200 parts of anthracene cyclic ketone, 20 to 50 parts of octaphenyl polyoxyethyiene, 20 to 50 parts of bisphenol A polyethenoxy ether, 20 to 50 parts of polyoxyethylene lauryl ether, 20 to 50 parts of alkylphenol polyoxyethylene, 50 to 80 parts of calcium dodecyl benzene sulfonate, 50 to 80 parts of sodium tripolyphosphate, 50 to 80 parts of sodium laurate, 10 to 20 parts of organosilicon waterproofing agent, and 10 to 20 parts of a stabilizing agent. The papermaking auxiliary agent mixture is convenient to prepare, is high in stability, is nontoxic, possesses no corrosivity, is easy to store, is convenient to be mixed with alkali liquor uniformly, and is low in foamability. The papermaking auxiliary agent mixture can be uniformly mixed with alkali liquor; boiling time is shorter than that of conventional auxiliary agents; yield is higher; slurry uniformity is higher; foam generated in production processes is less; and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an auxiliary agent used in the cooking and pulping process. Background technique [0002] Usually commercially available cooking aids used in the paper industry are compounds of anthraquinone and surfactants. Its principle of action is to use anthraquinone to remove lignin and protect fibers; Anthraquinone and lye penetrate into the interior of the raw material. The defect of this product is: anthraquinone is difficult to dissolve in water and lye, and surfactant is easy to generate a lot of foam. The product is difficult to mix evenly in the lye during use, and it is easy to produce precipitation in the lye, resulting in unstable process, poor slurry uniformity, and relatively large foam. A large amount of foam is accumulated in the working environment, which is difficult to operate. With the development of the paper industry, there is an urgent need for a cooking aid prod...

Problems solved by technology

The disadvantages of this product are: anthraquinone is insoluble in water and lye, and surfactants tend to generate a lot of foam

As a result, it is difficult to mix the product evenly in the lye during use, and it is easy to precipitate in the lye, resulting in unstable process, poor slurry uniformity, and relatively large foam. A large amount of foam accumulates in the working environment, making it difficult to operate
