Abstract

The invention discloses an anti-mildew paperboard and a preparation method thereof. The preparation method comprises the steps that 1, styrene-acrylic emulsion, nanometer titania, iron sesquioxide, carboxymethylcellulose, polyvinyl alcohol, talcum powder and water are mixed and molten, and a mixture M1 is prepared; 2, a paperboard is coated with the mixture M1 prepared in the step 1, and the anti-mildew paperboard is prepared, wherein the mixture M1 is prepared from 100 parts by weight of styrene-acrylic emulsion, 0.5-3 parts by weight of nanometer titania, 3-8 parts by weight of iron sesquioxide, 3-10 parts by weight of carboxymethylcellulose, 1-5 parts by weight of polyvinyl alcohol, 5-20 parts by weight of talcum powder and 10-30 parts by weight of water. By means of the design, the effects that mildewing can be effectively prevented, the use cost of the prepared paperboard is greatly reduced, and the preservation cost is reduced are achieved.

Description

technical field [0001] The invention relates to the field of production and preparation of cardboard, in particular to mildew-resistant cardboard and a preparation method thereof. Background technique [0002] As the production material of cartons, the properties of cardboard greatly affect the properties of the produced cartons. During the use of cartons, their wide application range often makes them placed in a wide range of environments. However, conventional cartons are often affected by the surrounding environment during storage and placement, especially in humid and cold environments. If the cartons are placed for a long time, they are prone to mildew and other problems, which makes the cartons unusable and causes serious damage. Big cost waste. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a mildew-resistant cardboard that can effectively prevent mildew, greatly reduce the use cost of the manufactured carton, and reduce ...
