Problems solved by technology

In the above-mentioned patents, the structure of the two layers of degradable plastics or paper sheets is poor, which has a small blocking effect on the gas released by the volatilization of the anti-mold mixture, resulting in a fast volatilization and release of the anti-mold mixture, which makes the use of the anti-mold sheet short.

Abstract

The invention relates to a slow-release mould-proof bag and a preparation method thereof. The slow-release mould-proof bag comprises mould-proof particles as well as an upper-layer permeable membraneand a lower-layer permeable membrane, wherein the upper-layer permeable membrane and the lower-layer permeable membrane are positioned on the outer side of the mould-proof particles; heat seal on edges of the upper-layer permeable membrane and the lower-layer permeable membrane is carried out together; a cavity body for accommodating the mould-proof particles is formed in the middle of the mould-proof bag; a structure of the upper-layer permeable membrane is identical to that of the lower-layer permeable membrane; both of the upper-layer permeable membrane and the lower-layer permeable membrane comprise PET (Polyethylene Terephthalate) membranes; permeable holes are formed in the PET membrane; PE (Polyethylene) membranes are arranged on the inner sides of the PET membranes; and non-woven fabrics are adhered to the outer sides of the PET membranes through glue layers. The slow-release mould-proof bag and the preparation method thereof disclosed by the invention has the advantages that apertures of the permeable holes formed in the four permeable layers through which gas volatilized by the mould-proof particles penetrates are gradually narrowed, a barrier to the gas is formed, a gaspassing path is extended during gas release, the gas permeability is reduced, and the release time can reach from one year to about one and a half year, so that the release time is greatly prolonged.

Description

technical field [0001] The invention relates to a slow-release anti-mildew package and a preparation method thereof. Background technique [0002] Anti-mildew sheet is a common agent for eliminating mildew in leather, furniture, clothing, etc. Its active ingredients are volatile materials such as chlorine dioxide and aromatic essential oils. In order to make it effectively play the role of anti-mildew, its effective parts must have good volatile properties. However, the common anti-mildew tablets currently on the market are made by embedding active ingredients in plastics, fillers and binders, and pressing them into tablets. For example, the application number is 201010262133.8, and the invention patent titled "an environmentally friendly, slow-release anti-mold tablet and its preparation method" discloses an environmentally-friendly, slow-release anti-mold tablet and its preparation method, which contains the following weight percentages: Raw materials: chlorine dioxide 2...
