Abstract

The invention provides a high-efficiency composite guanidine-based paper-making fungicide, which belongs to the technical field of paper-making fungicide production. In parts by weight, the fungicide comprises the following components: 10-30 parts of guanidine-based polymer, N-octyl 5-15 parts of isothiazolinone, 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, o-phenyl Potassium hydrogen diformate 0‑100 parts. The guanidine-based polymer is polyhexamethylene biguanide hydrochloride. Polyhexamethylene biguanide hydrochloride is broad-spectrum antibacterial, has killing ability to Gram-positive bacteria, Gram-negative bacteria, fungi and yeast, and can be used to produce antibacterial paper for health and hygiene products to replace silver-containing libraries At the same time, the polyhexamethylene biguanide hydrochloride solution also improves the physical properties of the paper, water absorption, strength after being wetted with water, and air permeability, so it is a papermaking fungicide with excellent performance. The synergistic effect is a compound TS-302 papermaking fungicide with high efficiency and broad spectrum.

Description

technical field [0001] The invention relates to the technical field of papermaking fungicide production, in particular to a 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 suitab...
