Problems solved by technology

[0003] At present, the development trend of building materials is green environmental protection, energy saving and emission reduction, but at the same time, it is necessary to take into account the properties of fire retardant, waterproof and immersion resistance, flexural and compressive resistance, etc., and the price is very expensive. Layer grid cloth strengthens the physical properties of the board, but the cost is high, and the wet board after paving is not perfect, and there are often apparent lack of material and blisters

Description

technical field [0001] The invention relates to a building material, in particular to a chopped strand reinforced board and a preparation method thereof. Background technique [0002] Building materials play a pivotal role in construction. Building materials are gradually developed with the improvement of human social productivity and science and technology. After the 20th century, the disadvantages of the performance and quality of building materials improved, and the varieties continued to increase. Chemical building materials mainly composed of organic materials emerged suddenly. Materials, anti-explosion and anti-radiation materials have emerged at the historic moment, and these materials provide a strong material guarantee for housing construction. In the current construction, the quality of the project is usually directly related to the quality of the materials used, the performance and the rationality of the use. Under the premise of meeting the same technical indic...
