Embodiment Construction
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, preferred embodiments are given below to further describe the present invention in detail. It is to be understood, however, that many of the details set forth in the specification are merely provided to provide the reader with a thorough understanding of one or more aspects of the invention, and that aspects of the invention may be practiced without these specific details.
[0028] (1) Prepare a glucose aqueous solution (coagulation retarder solution) according to the mass ratio of glucose and water to 1:1000.
[0029] (2) Weigh gypsum powder, biomass carbon fiber, biomass fiber (bagasse), water in proportion, the mass ratio is 1:0.05:0.05:0.5, the retarder solution in the above step (1) (the solution mass concentration is 1:0.05:0.05:0.5) 0.1%) the added mass accounts for 0.05% of the mass of the gypsum powder, and the foaming agent accounts for 0.10% of the mass of th...

Abstract
The invention discloses a preparation method of biomass carbon fiber reinforced gypsum board, which belongs to the technical field of biomass carbon fiber material. The patent of the invention uses bagasse as raw material to prepare biomass carbon fiber, which is used to strengthen gypsum board and improves the elasticity of gypsum board Modulus and maximum load; lower cost compared to other fiber reinforced gypsum boards. 1. Configure glucose aqueous solution (retarder solution). 2. First add the retarder solution into the water and mix it evenly in the mixer; then add the gypsum powder and mix it into a uniform slurry; then add the biomass carbon fiber and biomass fiber and continue stirring to mix it evenly. 3. Put the biomass carbon fiber / biomass fiber / gypsum mixed slurry into the wooden frame to form a flat slab, put it into the press machine, control the thickness with a thickness gauge, pressurize and place it at room temperature to make the gypsum Fully hydrated. Then the board is sent to the drying box to dry, and then the board is maintained at room temperature. The biomass carbon fiber / biomass fiber reinforced gypsum board prepared by the invention has relatively large elastic modulus and maximum load, and has broad application prospects in the energy-saving and environment-friendly construction industry.
Description
technical field [0001] The invention relates to the technical field of biomass carbon fiber materials, in particular to a preparation method of biomass carbon fiber reinforced gypsum board. Background technique [0002] Gypsum board has excellent properties such as light weight, high strength, convenient processing, sound insulation, heat insulation and fire prevention, and is widely used in interior partition boards of various buildings (office areas, residential areas, industrial plant areas, shops, hotels, etc.). Ground base board, ceiling, sound-absorbing board and various decorative boards, etc. At present, the commonly used gypsum board reinforcing fibers are synthetic fibers, such as glass fibers, carbon fibers, polypropylene fibers, etc., but these synthetic fibers have problems of high cost and environmental pollution. [0003] According to the literature, when glass fiber reinforced gypsum board is used, the interface between gypsum and glass fiber is improved aft...
