Problems solved by technology

However, due to the lack of slow-release technology, the anti-mold disk is not effective for a long time, and mildew spots may still appear after a period of time, and the anti-mold disk can only prevent itself from becoming moldy, and cannot prevent other non-mold-proof disks from becoming moldy
In addition, some medicines such as hygienic balls are placed in disks and tape boxes for anti-mold preservation, and the camphor drugs released by medicines such as hygienic balls have a certain corrosion effect on disks and tapes. Dangerous and harmful, prone to loss of information

Abstract

The invention provides a medicament for preventing mildew of information recording materials, which is used for preventing mildew of various magnetic disks and magnetic tapes. This long-acting anti-mildew drug is made of the following raw materials in weight ratio: p-nitrobenzaldehyde: 10-70%, α-bromocinnamaldehyde: 10-70%, salicylic acid: 5-40% %, stearic acid: 0.5-20%. The drug of the invention can release anti-mold drugs dozens of times the minimum antibacterial dose, has high-efficiency killing or inhibiting ability to common molds in the air, and can ensure that various information recording materials such as disks, tapes, and CDs do not grow mold.

Description

technical field [0001] The invention relates to an anti-mildew agent and a technology for preventing mildew of information recording materials such as disks, magnetic tapes, and optical discs. Background technique [0002] As a high-tech product, information recording materials have developed rapidly. At present, they have been widely used in scientific research, document management, information exchange, and file preservation. With the further development of high-tech, information recording materials will become increasingly important. How to properly preserve information recording materials has become a hot spot and focus of current research. Mold is one of the biggest weaknesses of information records. The toxins produced by mold can corrode information recording materials, destroy record content, and damage files in a short period of time. It can be seen that mold is the "bottleneck" factor that restricts the proper preservation of information recording materials. At ...
