Problems solved by technology

[0002] In the past, the treatment of straw in rural areas was generally incineration, which not only polluted the environment but also caused a waste of resources.
In recent years, there have been examples of comprehensive utilization of straw, such as the application of straw boards to decorative boards, etc., but most of the decorative boards are made of a mixture of organic materials (MDI) and straw powder, and their fire resistance is poor.
The Chinese Utility Model Patent No. 94240266.9 provides a composite plasticized board with straw powder added, but its fireproof performance, heat insulation performance and strength are still not ideal, and the components are easy to dissolve when exposed to water

Abstract

The invention discloses a non-combustible straw decorating plate and a manufacturing method thereof. The non-combustible straw decorating plate consists of a glass fiber cloth layer and a slurry layer which is coated outside the glass fiber cloth layer, wherein the slurry layer consists of aluminum oxide, magnesium oxide, straw, expanded perlite and magnesium chloride. The manufacturing method comprises the following steps of: A, uniformly mixing raw materials according to proportion at normal temperature and normal pressure, and then pouring the mixture into a sealed vacuum kettle; B, preparing 2 to 10mol / L solution of magnesium chloride, regulating the pH value to 6.5 to 9.5, adding the prepared solution of magnesium chloride into the sealed vacuum kettle for stirring, and extracting air from the sealed vacuum kettle with stirring until the pressure in the sealed vacuum kettle reaches 0.1 to 0.5atm; and C, coating the stirred slurry on the glass fiber cloth, and rolling the glass fiber cloth which is coated with the slurry to form a plate. The decorating plate has the advantages of high strength, compactness and fireproof and heat insulation performance, high-temperature resistance, environmental friendliness, no hazardous substance, difficult dissolution when meeting water components, and full utilization of crop straw.
