Problems solved by technology

[0002] Paper-faced gypsum board is the material of choice for today's house partitions. It has breathability and can absorb moisture. At the same time, it contains a variety of organic components; in places with high humidity, especially in southern regions, paper-faced gypsum boards are prone to mildew during use. Phenomenon, these molds directly affect people's life and health; the preparation method of anti-mold gypsum boards currently on the market is mainly to directly mix anti-mold liquid into gypsum core boards, which cannot effectively prevent the growth of mold

Embodiment 1

[0019] The mildew-proof paper-faced gypsum board of the present invention includes a gypsum core board and face-protecting paper, the surface of the gypsum core board and the face-protecting paper are bonded together through an adhesive layer. Including: 500g of desulfurized gypsum, 325g of water, 3g of starch, 0.3g of foaming agent, 0.1g of sodium tetraborate (commonly known as borax), and two sheets of face-protecting paper with a size of 300mm*300mm.

[0020] The preparation method of mildew-proof paper-faced gypsum board of the present invention is as follows:

[0021] A. Dry mix the desulfurized gypsum and starch of the above quality evenly, wet mix the foaming agent and water evenly, pour the above dry material into the wet material, and mix it into a slurry. Before the initial setting of the slurry, pour the slurry In the mold pressed with protective paper, a layer of protective paper is attached to the surface of the slurry, and a heavy object is pressed until the slur...

Abstract

The invention provides a method for preparing a mildew-proof paper surface gypsum plaster board. According to the method, during the drying stage of the paper surface gypsum plaster board, an atomized mildew preventive solution is sprayed onto the surface of the paper surface gypsum plaster board under a vacuum condition. By means of the preparation method, growth of molds on a bonding layer between covering paper and a gypsum core board can be effectively prevented.
