preparation example Construction

[0036] The preparation method of the inorganic cementitious material product comprises the following steps: stirring and mixing the inorganic cementitious material, plastic powder and water to obtain a mixture; solidifying the mixture according to a predetermined shape to form a pre-product, and under the predetermined shape, the thickness of the pre-product is less than or equal to 20mm; heat the preform at a specified temperature, and the specified temperature is used to make the plastic powder in the preform in a molten state; cool the heated preform to obtain an inorganic cementitious material product with a thickness of less than or equal to 20mm .

[0037] In the embodiment of the present application, by stirring and mixing the inorganic cementitious material, plastic powder and water, the plastic powder is dispersed in the inorganic cementitious material, so that when the mixed and dispersed mixture is cured to form a pre-product, the plastic powder will be in the inorga...

Embodiment 1

[0075] This embodiment provides an inorganic cementitious material product, which, in parts by weight, includes: 95 parts of inorganic cementitious material and 5 parts of plastic powder. The inorganic cementitious material is gypsum powder, and the plastic powder is PE.

[0076] This embodiment also provides a preparation method of an inorganic cementitious material product. The preparation method is prepared according to the following steps: placing gypsum powder, PE and water in a stirring tank, stirring evenly with a stirring rod, and obtaining a slurry mixture; pour the mixture into a plate-shaped mold, solidify and form at normal temperature and pressure, and obtain a flat-plate preform after demoulding; put the flat-plate preform into a constant temperature furnace, and heat it for 0.3h under the condition of air atmosphere and 150°C; The heated preform was cooled to obtain an inorganic cementitious material product, and the thickness of the inorganic cementitious mater...

Embodiment 2

[0078] The difference between this embodiment and the first embodiment is only that the weight parts of the inorganic cementitious material and the plastic powder are different. In this embodiment, the inorganic cementitious material products, in terms of weight parts, include: 90 parts of inorganic cementitious materials , 10 parts of plastic powder. The inorganic cementitious material is gypsum powder, and the plastic powder is PE.

Abstract

The invention relates to the technical field of inorganic cementing material products, in particular to an inorganic cementing material product and a preparation method thereof. The inorganic cementing material product comprises the following components in parts by weight: 65-90 parts of an inorganic cementing material and 10-35 parts of plastic powder, the preparation method of the inorganic cementing material product comprises the following steps: stirring and mixing an inorganic cementing material, plastic powder and water to obtain a mixture; the mixture is cured and formed according to a preset shape to form a prefabricated product, and the thickness of the prefabricated product is smaller than or equal to 20 mm under the preset shape; heating the prefabricated product at a specified temperature, wherein the specified temperature is used for enabling the plastic powder in the prefabricated product to be in a molten state; and cooling the heated prefabricated product to obtain the inorganic cementing material product with the thickness of less than or equal to 20mm. According to the inorganic cementing material product and the preparation method thereof, the low cost can be ensured, the preparation conditions are not harsh, and the thinner inorganic cementing material product with good toughness can be prepared.

Description

technical field [0001] The present invention relates to the technical field of inorganic cementitious material products, in particular to an inorganic cementitious material product and a preparation method thereof. Background technique [0002] Common inorganic cementitious material products include cement products, gypsum products, etc. These products are widely used in various fields such as construction and life. However, cement products and gypsum products are limited by material properties, and only products with thicker thickness can be prepared to ensure the strength and toughness of the products, otherwise they will easily become brittle and brittle. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an inorganic cementitious material product and a preparation method thereof, which can ensure that the cost is low, the preparation conditions are not harsh, and the inorganic cementitious material product with thinness and good toughn...
