Description

Complex enzyme mildew-removal cleaning tablet and preparation method and application thereof Technical Field The application relates to the technical field of detergents, in particular to a composite enzyme mildew-removal cleaning sheet, and a preparation method and application thereof. Background In a humid environment, mould is easy to grow on the surface of specific hard organic materials such as plastics, rubber and the like, formed bacterial plaques and biological films not only seriously affect the appearance and generate peculiar smell, the released spores are more likely to cause allergy and harm health, and the aging and degradation of the materials are accelerated. The mildew removing products in the current market are mainly divided into two types, namely a liquid agent and a solid tablet, but have obvious defects aiming at the long-acting mildew preventing requirements of special surfaces such as plastics, rubber and the like. Although the liquid mildew remover has strong instant oxidation sterilization capability, the liquid mildew remover has heavy pungent smell and strong fluidity, is difficult to effectively stay on vertical or curved surfaces, and has short acting time and incomplete treatment, and more importantly, the strong corrosive components therein easily damage plastic and rubber substrates, and lead the surfaces of the plastic and rubber substrates to be hard, brittle or fade. The common solid cleaning tablet mainly depends on the combination of oxidizing agents such as sodium peroxycarbonate and the like and effervescent agents, and focuses on broad-spectrum decontamination and basic sterilization. However, the products generally lack specific decomposition capability for the cell walls of the mould and the biomembrane matrix thereof, and the mycelium structures which are deeply penetrated into micropores of the materials cannot be thoroughly removed, so that the mould removal is not thorough, and the mould recurrence rate is high. Therefore, there is a need to develop a composite enzyme mildew-proof cleaning sheet and a preparation method thereof, so as to solve the problems of incomplete cleaning and lack of long-acting mildew-proof function in the prior art. Disclosure of Invention Aiming at the defects in the prior art, the application aims to provide a composite enzyme mildew-removing cleaning sheet, and a preparation method and application thereof.
