Abstract

The invention discloses an attapulgite mildew-resistant plasterboard. The attapulgite mildew-resistant plasterboard comprises the following raw materials in parts by weight: 30-60 parts of acidified paste-shaped attapulgite clay, 5-15 parts of methylisothiazolinone, 5-15 parts of dodecyl dimethyl benzyl ammonium chloride, 0.5-5 parts of methylparaben, 0.5-5 parts of propylparaben, 40-60 parts of pearl sand, 250-350 parts of natural dihydrate gypsum, 20-40 parts of epoxy resin casting glue, and 60-80 parts of deionized water. The attapulgite mildew-resistant plasterboard has the advantages of hard quality, acid and alkali resistance, aging resistance and mildew resistance and antibiosis, the raw material cost is low, the preparation method is simple, and the attapulgite mildew-resistant plasterboard has high practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an attapulgite mildew-resistant gypsum board and a preparation method thereof. Background technique [0002] With the development of the construction industry and the requirements of various interior decoration, the application of gypsum board is more and more extensive. Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. [0003] The lightweight partition wall composed of gypsum sheets or hollow gypsum strips can be used to separate indoor spaces, and has the characteristics of simple structure, easy processing and installation. At the end of the 19th century, various countries began to use gypsum boards as interior...
