Abstract

The invention belongs to the field of packaging, and discloses mildewproof and antibacterial composite glue and a paper board. The mildewproof and antibacterial composite glue is prepared from ingredients of sticky rice glue and a mildewproof and antibacterial agent, wherein the mildewproof and antibacterial agent is coffee slag powder, green tea extracts or free mixtures of the coffee slag powderand the green tea extracts. Through being metered by dry weight, the mass ratio of the sticky rice glue to the mildewproof and antibacterial agent is (3 to 10) to 10. The mildewproof and antibacterial composite glue can be used for preparing packaging materials or wrappage, such as a mildewproof and antibacterial composite paper board, the good mildewproof and antibacterial effect is achieved. The mildewproof and antibacterial composite glue and the environment-friendly composite paper board have the advantages that the materials are selected from natural waste materials; the natural adsorption and antibacterial characteristics are realized; the advantages of safety and environment protection are also realized.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to an anti-mold and antibacterial compound glue, an anti-mold and anti-bacterial environment-friendly composite cardboard and a preparation method thereof. Background technique [0002] With the improvement of living standards, people have higher requirements for the placement and storage of daily necessities such as clothing, footwear and luggage products. During the storage period of clothing, shoes, bags, etc., the moisture and humidity in the air are suitable for the growth of mold and breed mold. It makes consumers have to spend a lot of manpower and material resources to clean and clean these clothes and shoes. If they are not handled carefully, they may even cause allergies and other symptoms. [0003] With the abundance of food supply, the storage and preservation requirements of fruits and vegetables are also increasing. How to avoid food mildew to protect people's phy...
