Building board and manufacturing method thereof

Abstract

The invention discloses a building board. The component of the building board comprises 70-90 parts of magnesian binding materials, 6-10 parts of crop straw powder, 6-10 parts of coal ash hollow particles and 2-4 parts of glass fibers. Specifically, the component comprises 80 weight parts of magnesian binding materials, 8 weight parts of crop straw powder, 8 weight parts of coal ash hollow particles and 2 weight parts of glass fibers. The invention also discloses a manufacturing method for the building board, which comprises the following steps: preparing a magnesian binding material solution; adding the coal ash hollow particles and the crop straw powder into the magnesian binding materials; uniformly stirring and then pouring into a mould, thereby obtaining a primary end-product; and planting the glass fibers into the primary end-product, curing and molding, thereby obtaining an end product. In the formulation of the building board, due to the particularity of the structure composition of the coal ash hollow particles, the prepared board has various tiny holes after the coal ash hollow particles are mixed with various raw materials, thus, the building board has a heat-insulating function.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a building board and a manufacturing method thereof. Background technique [0002] At present, in the field of construction, red bricks, porous bricks, hollow bricks, etc. are usually used as the main materials for building walls; It is made of bricks; after the bricks are planned and stacked, and then cement is added to fix the shape, the wall of the building is formed; however, this traditional material itself does not have thermal insulation effect, resulting in poor thermal insulation of the wall. To achieve the thermal insulation of the house wall, it is necessary to add a separate layer of thermal insulation layer on the surface of the wall to make the wall have the effect of thermal insulation. However, adding a separate thermal insulation layer not only increases the complexity of building construction, but also increases the intensity of labor construction. Large, but ...

[0002] At present, in the field of construction, red bricks, porous bricks, hollow bricks, etc. are usually used as the main materials for building walls; It is made of bricks; after the bricks are planned and stacked, and then cement is added to fix the shape, the wall of the building is formed; however, this traditional material itself does not have thermal insulation effect, resulting in poor thermal insulation of the wall. To achieve the thermal insulation of the house wall, it is necessary to add a separate layer of thermal insulation layer on the surface of the wall to make the wall have the effect of thermal insulation. However, adding a separate thermal insulation layer not only increases the complexity of building construction, but also increases the intensity of labor construction. Large, but also a waste of raw materials
