Abstract

The invention relates to a plant fiber light wall and a manufacturing method thereof. The plant straw renewable waste content in the raw material may reach over 50 percent; active silicon dioxide is adopted in the formula, so the absorbability and fire resistance are improved, the fire-proof, water-proof, anti-frost-cracking, anti-aging-cracking or related performances of the wall plate are realized, the product is suitable to be used both indoor and outdoor, and the application range of the product is expanded; the production process is simple and environment-friendly, large hot-pressing equipment is not needed, waste gas, waste residue and greenhouse carbon dioxide gas are not generated in a production process, and real low-carbon and environment-protection purposes are fulfilled; and the formula of the raw material is mainly plant straws, and the produced product is green building material which is nontoxic, odorless, pollution-free, and radiation-free. The method has the characteristics of environment friendliness, energy conservation, high waste utilization rate, simple process, low cost and the like.

Description

technical field [0001] The invention relates to a lightweight wall and a manufacturing method thereof, in particular to a plant fiber lightweight wallboard and a manufacturing method thereof. Background technique [0002] In our country, as the country prohibits the production and use of clay solid bricks, many companies have begun to develop hollow wall panels for walls. Most of them are produced using chemical raw materials, which is a burden on the environment and energy. Many enterprises use agricultural waste plant straw as raw material to produce wallboard, and add adhesives, flame retardants, reinforcing agents, etc., although the use of straw waste meets the requirements of green environmental protection, but some of its additives are high energy consumption cement , and some are toxic or difficult to decompose chemical components, which do not really achieve environmental protection, especially in the process of processing, which basically needs to be processed by h...
