Abstract

The invention provides a novel efficient composite guanidyl papermaking bactericide, and belongs to the technical field of papermaking bactericide production. The bactericide comprises following components in parts by weight: 10-30 parts of a guanidyl polymer, 5-15 parts of 2-octyl-2H-isothiazol-3-one, 150-450 parts of diethylene glycol, 0.5-1.5 parts of dodecyl dimethyl benzyl ammonium chloride,0.3-1.8 parts of hydroxymethyl cellulose and 0-100 parts of potassium hydrogen phthalate, wherein the guanidyl polymer is polyhexamethylene biguanidine hydrochloride. Polyhexamethylene biguanidine hydrochloride is a broad-spectrum antibacterial product, has killing capacity on Gram-positive bacteria, Gram-negative bacteria, fungi and saccharomycetes and can be used for producing and manufacturingantibacterial paper for health products to replace silver-containing Kuerxin paper, and meanwhile, a polyhexamethylene biguanidine hydrochloride solution also improves physical properties and hygroscopic property of the paper and strength and breathability of the paper stained with water, so that the solution is a papermaking bactericide with excellent performance; the bactericide is one efficientand broad-spectrum composite type TS-302 papermaking bactericide under the synergistic effect of the components.

Description

technical field [0001] The invention relates to the technical field of papermaking fungicide production, in particular to a novel high-efficiency composite guanidine-based papermaking fungicide. Background technique [0002] Papermaking is one of the four great inventions of ancient science in my country, and it is also an outstanding contribution made by the Chinese people to the development of world science and culture. With the continuous improvement of modern civilization and printing, papermaking technology has experienced numerous innovations and innovations in the field of application. Change, to achieve a step-wise leap. In recent years, with the application of the white water closed system, the increase of the speed of the paper machine, the "zero" discharge of the white water of the paper machine and the emphasis on the chemicals in the wet end of the paper machine, the pulp fluid is rich in carbon sources, nitrogen sources and minerals. Substances, coupled with a ...
