Problems solved by technology

The method of mixing short fibers into gypsum ingredients to achieve reinforcement, due to the limitation of the existing mixing process, it is difficult for short fibers to be evenly mixed into gypsum ingredients, resulting in an obvious phenomenon of uneven strength distribution
Bonding the short fiber mat to the surface of the gypsum board core can properly improve the strength of the gypsum board, but this bonding structure cannot make the short fiber mat play a real strengthening function, so the improvement of the strength of the gypsum board is very limited
Fiber mesh reinforcement, due to the limitation of fiber mesh production technology, it is difficult to achieve the ideal degree of fiber density and reinforcement uniformity

Abstract

The invention relates to an environmentally friendly graphite gypsum board and a preparation method of the environmentally friendly graphite gypsum board, and solves the technical problems in the prior art that the thermal insulation property of the gypsum board is poor and the compressive strength and the bending strength are both relatively poor. The invention provides the environmentally friendly graphite gypsum board. The environmentally friendly graphite gypsum board is prepared from the following material components by weight: 30-60 parts of gypsum powder, 60-120 parts of calcium carbonate powder, 12-30 parts of titanium dioxide, 4-6 parts of pulverized fuel ash, 20-30 parts of expanded graphite, 4-16 parts of fiberglass, 4-16 parts of short carbon fiber, 14-16 parts of polyvinyl alcohol, 11-15 parts of sodium carboxymethylcellulose, and 90-180 parts of water; meanwhile, the invention further provides the preparation method of the environmentally friendly graphite gypsum board. The environmentally friendly graphite gypsum board is widely applied in the fields of building materials.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environmentally friendly graphite gypsum board and a preparation method thereof. Background technique [0002] Gypsum board is widely used in interior partition walls, wall cladding panels (instead of plastering layers), ceilings, sound-absorbing panels and various decorative panels in various buildings such as residences, office buildings, shops, hotels and industrial plants. Building materials; Compared with lime and cement, it has the advantages of light weight and easy processing. However, although the quality of gypsum board is lighter than that of lime and cement, it is still a material with high weight, which increases the difficulty of transportation and installation of gypsum board, and the consumption of raw materials is high, the cost is high, and the thermal insulation of gypsum board is not good. . [0003] Moreover, the disadvantages of existing gypsum boards,...
