Abstract

The invention discloses an environmentally-friendly gypsum board, which comprises the following raw materials: 1-3 parts of outer layer paper, 50-60 parts of hemihydrate gypsum, 20-50 parts of activediatomaceous earth, 6-10 parts of a lime mixture, 8-12 parts of white carbon black, 4-8 parts of montmorillonite, 80-90 parts of water, 5-20 parts of talc powder, 0.01-0.3 part of citric acid, 0.1-0.5part of cellulose, 0.1-0.3 part of amino acid, 1-3 parts of a polycarboxylic acid water reducer, 10-20 parts of honeysuckle, 5-10 parts of typha angustifolia, 20-40 parts of maifanite, 10-15 parts ofzeolite, and 15-30 parts of tourmaline. According to the present invention, the auxiliary raw materials for producing the gypsum board contain honeysuckle, typha angustifolia, maifanite, zeolite andtourmaline, such that the preparation scheme is reasonable, pollution caused by formaldehyde and bacteria can be well eliminated, pollution caused by formaldehyde and bacteria in the paper surface gypsum board can be substantially reduced, and the obtained gypsum board is basically harmless to human body, has the substantially improved performance parameters such as compressive strength, thermal conductivity, water absorption expansion rate and the like, is completely superior to the similar products in the market, and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of gypsum boards, in particular to an environment-friendly gypsum board. Background technique [0002] 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. As one of the new lightweight panels, gypsum boards have been widely used in interior partition walls, wall cladding panels (instead of plastering layers), ceilings, Sound-absorbing panels, ground-based panels and various decorative panels, etc. The gypsum boards produced in my country mainly include: paper gypsum boards, decorative gypsum boards, gypsum hollow strips, fiber gypsum boards, gypsum sound-absorbing panels and anchor point gypsum boards. [0003] At present, the methods of controlling formaldehyde pollution on the market are mainly physical adsorption and chemical remo...
