Problems solved by technology

[0003] Traditional asbestos tiles not only contain carcinogenic ingredients, but are also prohibited from being used due to their short service life, perishable pollution, and unsightly appearance. However, the emerging color steel tiles have high cost, short lifespan, no sound insulation and heat insulation, and are easy to rust. Difficult to solve
[0004] In addition, traditional reinforced concrete building materials use some non-renewable ore raw materials, which will cause resource depletion in the long run, and the production process will be accompanied by huge energy consumption and a large amount of greenhouse gas emissions; secondly, traditional reinforced concrete is heavy and difficult to carry , poor fire resistance, and poor seismic performance; there is still discharge pollution in the re-production process, and industrial waste water and waste residues will be generated during the production process, accompanied by harmful substances such as dust, radioactive gases, and formaldehyde, which will affect long-term living. Residents' health, causing serious social harm

Abstract

The invention discloses a straw building material formula and a preparation method thereof, and relates to the technical field of building material preparation methods. The straw building material formula comprises the following components by weight: 45-50% of straw, 10-16% of magnesium oxide, 15-20% of magnesium chloride, 5-12% of light sodium carbonate, 10-15% of volcanic ash, and 3-5% of a modifier. The building material prepared from the ecological straw has the advantages of low cost, no pollution, no radioactivity, no formaldehyde, fire resistance, water resistance, excellent environmental protection property and wide applicability.

Description

technical field [0001] The invention relates to the technical field of building material preparation methods, and more specifically relates to the technical field of straw building material formula and its preparation method. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. Straw is an efficient and long-term raw material for light industry, textiles and building materials. It can not only partially replace bricks, wood and other materials, but also effectively protect cultivated land and forest resources. [0003] Traditional asbestos tiles not only contain carcinogenic ingredients, but are also prohibited from being used due to their short service life, perishable pollution, and unsightly appearance. However, the emerging color steel tiles have high cos...
