Embodiment
[0024] Embodiment: the manufacture method of magnesium-based floor base material, its step:
[0025] S1. Prepare fiber powder; wherein, the fiber powder is formed by crushing fiber materials such as wood fiber, bamboo fiber, and crop straw.
[0026] S2. Mix fiber powder, magnesium-based cementitious material and water to form a semi-dry material, so that the semi-dry material is kneaded into a ball by hand and loosened by hand. The magnesium-based cementitious material is made of magnesium oxysulfate cement or oxychloride cement. Magnesium cement is the main material;
[0027] S3, evenly spreading the semi-dry material on the pallet;
[0028] S4, pressing the semi-dry material;
[0029] S5. Maintaining pressure and curing at high temperature.
[0030] Inorganic cementitious materials include Portland cement, gypsum, etc. The pH value of Portland cement is about 12, which belongs to high alkali cement. The combination of fiber powder and high alkali will decompose xylitol ...

The invention relates to a production method of a magnesium-based floor base material. The problems that in the prior art, a lot of green energy is consumed by wood flours, the wood flours have residual formaldehyde which affects health, and the like are solved. According to the technical scheme, the method comprises the steps that 1, fiber powder is prepared; 2, the fiber powder, a magnesium-based cementitious material and water are mixed to form a half-dry material, and the half-dry material is made to be in a state where the half-dry material is agglomerate when pinched by hands, and is loose when not gripped by the hands; 3, the half-dry material is evenly laid on a layer board; 4, the half-dry material is pressed; 5, the pressure is maintained, and high-temperature maintenance and curing are conducted. The production method of the magnesium-based floor base material has the effects that after the raw materials are mixed, the half-dry material is formed, thus a finished product hasmore fiber components and less cementitious material, by attaching grainy paper or patch to the surface of the base material, a grainy effect of the magnesium-based floor base material can be achieved, the magnesium-based floor base material can be conveniently applied to the field of floors, and grooves can be conveniently formed in the magnesium-based floor base material.
Description
technical field [0001] The invention relates to a manufacturing method of a magnesium-based floor substrate. Background technique [0002] Existing floor base material has two kinds, and a kind of is the solid wood floor base material with a long history; Another kind is the artificial floor base material that wood fiber adds organic glue bonding. [0003] Among them, the solid wood floor base material is natural and environmentally friendly, which is the product of choice for users. However, there are problems such as wasting forestry resources, combustible wood, and lack of fire prevention. [0004] The advantage of artificial floor substrates (artificial fiberboard, particleboard) is to save logs, which can be made by crushing branches and shrubs and bonding them with organic glue. The disadvantage is that organic adhesives (glue) contain formaldehyde, which affects health. Moreover, glue and wood powder are combustible and cannot meet the fire protection requirements....
