Embodiment Construction

[0014] The waterproof fiber gypsum board is composed of the following raw materials in parts by weight: 32-36 parts of wood fiber, 50-55 parts of dihydrate gypsum, 4-6 parts of glass fiber silk, 5-8 parts of acrylic acid emulsion, 3-5 parts of inorganic aluminum salt Waterproofing agent, 50-60 parts of industrial waste water, the specific preparation method of fiber gypsum board is as follows:

[0015] 1), the preparation of wood fiber, be that 1:2-3 coconut bark, pine bark are pulverized into the bark chipping that particle diameter is 0.5-1.5mm with pulverizer with weight ratio, then above bark chipping is put Soak in a soaking pool with a weak acid solution for 2-4 hours, reciprocate 2-4 times, combine the soaking liquid after suction filtration and distill it together to get final product;

[0016] 2), mix the wood fiber obtained in step 1) with dihydrate gypsum and glass fiber silk, and add industrial wastewater with 40-60% of the weight of gypsum at the same time, stir f...

Abstract

The invention discloses a waterproof fiber plasterboard. The waterproof fiber plasterboard comprises, by weight, 32-36 parts of wood fibers, 50-55 parts of dihydrate gypsum, 4-6 parts of glass fibers, 5-8 parts of an acrylic acid emulsion, 3-5 parts of an inorganic aluminum salt waterfroof agent and 50-60 parts of industrial waste water. A preparation method of the waterproof fiber plasterboard comprises the followings steps. The waterproof fiber plasterboard utilizes the wear-resistant components, guarantees plasterboard strength and hardness and has good wear resistance.

Description

[0001] technical field [0002] The invention relates to the field of building materials used for interior decoration, in particular to waterproof fiber gypsum boards. [0003] Background technique [0004] Gypsum board is widely used in building decoration materials because of its light weight, high strength, sound insulation, heat insulation, fire prevention, and easy processing. The wear resistance of gypsum board is average, and it is a direction of research in building materials, but its application range still needs to be developed. [0005] Contents of the invention [0006] The object of the present invention is to provide a waterproof fiber gypsum board, in which a wear-resistant formula is added to ensure the strength and hardness of the gypsum board while having good wear resistance. [0007] Technical scheme of the present invention is as follows: [0008] The waterproof fiber gypsum board is composed of the following raw materials in parts by weight: 32-36...
