Problems solved by technology

In the formula composition of the building board, due to the particularity of the structure and composition of the fly ash hollow microspheres, after mixing with various raw materials, the board itself can have a variety of tiny pores. Therefore, the building board It has the function of heat preservation; but due to its relatively simple composition, the performance of the prepared building board is poor, which cannot meet the actual production and application; and the prepared building board is relatively heavy and difficult to move

Abstract

The invention relates to a high-strength lightweight composite building sheet material. The high-strength lightweight composite building sheet material comprises the following components in parts by weight: 80-100 parts of a magnesium cement material, 8-12 parts of crops straw powder, 6-10 parts of fly ash hollow microspheres, 8-12 parts of polybutyrolactam fibers, 5-7 parts of polycarbosilane fibers, 8-12 parts of urea-formaldehyde resin, 4-8 parts of butyl rubber, and 3-5 parts of polypropylene adipate; wherein the particle size of the magnesium cement material is 60-80 micrometers; and the magnesium cement material comprises magnesium chloride and magnesium oxide with weight proportion between 1 and 2. The high-strength lightweight composite building sheet material has the characteristics of high intensity, light weight and thermal insulation performance.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a high-strength and lightweight composite building board. 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,...
