Description

technical field [0001] The invention relates to the technical field of antifungal agents, in particular to a compound antifungal agent for special papermaking. Background technique [0002] Papermaking is an important invention of the working people in ancient China. There are two forms of mechanism and manual. The mechanism is carried out continuously on the paper machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and is initially dehydrated in the wire part of the paper machine to form a wet paper sheet, which is then dehydrated by pressing, and then dried into paper. [0003] Special paper, also known as special processed paper, is made of different fibers into paper with special functions by paper machine, such as synthetic fiber, synthetic pulp or mixed wood pulp and other raw materials, which are modified or processed with different materials to give Different functions and uses of paper, such as used in daily life, buildin...

Problems solved by technology

With the vigorous development of my country's national economy and the continuous improvement of people's requirements for paper quality, the sterilization and mildew prevention of paper is becoming more and more important. The existing antifungal agents for papermaking have a single function and can only sterilize a single strain. When different pulps are sterilized, it is easy to cause the antifungal agent to lose its effect and cannot play a bactericidal effect
