Problems solved by technology

[0002] Cement partition board is a new type of building material, which is mainly used for indoor partitions, replacing traditional brick walls, which are complex in construction and not suitable for modern buildings
Therefore, in the selection of partition boards, it is necessary to choose cement boards with high strength and light weight. In the prior art, light cement boards are generally made of foam materials, but their strength is poor, and glass fibers are generally used to make them. Reinforcement, but glass fiber and cement are two systems after all. In the destructive test, it can be found that the strength of cement and glass fiber is different. The ideal state is that both of them break at the same time. Fibers have a limited range of reinforcement

Abstract

The invention relates to a cement partition plate, which is prepared from the following components in parts by weight: 40-60 parts of cement, 40-50 parts of perlite, 0.5-1.5 parts of 20-30 mm glass fiber, 0.5-2 parts of a foaming agent, 0.5-2 parts of a water repellent, 1-2 parts of alpha-hydrogen-omega-hydroxyl-polydimethylsiloxane, 4-8 parts of polysilane, 1-4 parts of polyethyl silicate and 0.5-1 part of a catalyst. The invention provides a light low-density high-strength glass fiber reinforced cement partition plate.

Description

technical field [0001] The invention relates to a building material, more specifically to a cement partition board. Background technique [0002] Cement partition board is a new type of building material, which is mainly used for indoor partitions, replacing traditional brick walls.

Therefore, in the selection of partition boards, it is necessary to choose cement boards with high strength and light weight. In the prior art, light cement boards are generally made of foam materials, but their strength is poor, and glass fibers are generally used to make them. Reinforcement, but glass fiber and cement are two systems after all. In the destructive test, it can be found that the strength of cement and glass fiber is different. The ideal state is that both of them break at the same time. Fibers have a limited range of reinforcement. Contents of the invention [0003] Aiming at the deficiencie...
