Baking-free plant straw building wall material and production method thereof

Abstract

The invention discloses a baking-free plant straw building wall material and a production method thereof. The wall material is mainly obtained by the following steps: mixing the following components in parts by weight: 5-20 parts of light calcium carbonate, 10-30 parts of bentonite, 5-15 parts of silicon ash, 2-5 parts of triethanolamine, 1-3 parts of organic silicon and 15-25 parts of cotton straw powder; adding 40-55 parts of modified sodium carbonate for abundantly and evenly stirring; and placing the mixture in an extrusion forming machine for extrusion formation under the pressure of 10-15 Mpa so as to obtain the building wall material. Compared with the prior art, the wall material disclosed by the invention is naturally solidified at room temperature after raw material smashing, stirring and extrusion forming, thus production process is extremely simple, and the produced product has the characteristics of light weight, low energy consumption, no pollution, corrosion resistance, dampproof property, mothproof property and the like and can be widely applied to walls, wallboards and sound insulation plates in the field of buildings.

Description

technical field [0001] The invention relates to a building wall material produced by using plant straws as raw materials and a production method thereof, in particular to a non-burning type building wall material produced by using cotton straw raw materials and a production method thereof. Background technique [0002] At present, a large number of orange stalks produced by agricultural production, especially a large number of cotton stalks produced in cotton production areas in my country, are crushed and returned to the fields as fertilizers. However, the long-term use of this treatment method will increase the possibility of crop diseases. The value of utilization is also low; second, as a fuel, the value of its utilization is greatly reduced, and some are treated as waste, such as incineration, which not only causes waste of resources, but also pollutes the environment. [0003] At present, the industrial utilization of cotton straw mainly includes the following types. ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is used to make compressed fiberboard, and due to technological reasons, such as a large amount of adhesive must be added, especially if it contains a certain amount of formaldehyde, and it will be harmful to the human body when used as a civil building material. Due to the process, its strength is generally low, and its use is limited.

[0005] 2. As a raw material for papermaking, but at present, many agricultural production areas, especially the northern arid areas, use a large number of plastic film planting models, and a large amount of old plastic film is also mixed in when recycling orange stalks, which is a fatal problem for papermaking. Separate them Very difficult, almost impossible according to current processing methods, thus making it unusable for papermaking

[0006] CN101417459A discloses a method and material for making wood-plastic composite materials by using plant straws and waste plastics, in which a method for utilizing cotton straws is proposed, and the recovered cotton straws are crushed and mixed with waste and old plastics, and composite additives are added to the Molding under high temperature and high pressure, this method needs to add plastics and compounding additives, the manufacturing process is complicated and the energy consumption is high, especially the use of a large amount of plastics, which weakens the environmental protection effect
