Biomass composite material wall modules and processing technology thereof

Abstract

The invention provides a composite material of environmental protection wall module, which mainly consists of a plant fiber, a self-made biomass adhesive, a moisture proofing agent, a biomass perfume etc., wherein the plant fiber comprises various crop straws and smashed sawdust which is cut into a length of 1 to 8 cm; the self-made biomass adhesive comprises a modified corn starch adhesive, a tapioca starch adhesive, a soybean crude protein adhesive and a trash for sugar beet processing; the moisture proofing agent is a calcium oxide; the perfume includes lavender, camphor tree particulate and argy wormwood. The wall consists of an internal wall surface and an external wall surface wherein the internal wall surface is abrasive, which is easy to ensure surface to be finished when in interior decoration; furthermore, the perfume such as the lavender, the camphor tree particulates and the argy wormwood etc. are added, so that a fragrance generated from the perfume gives out slowly when the wall is in use, and the goal of beautifying the indoor air environment and anti mosquitoes are achieved. The external wall surface is fine sand coated to form a smooth and rigid housing which can improve the strength of the surface and be good for ventilation of outer atmosphere. The production flow comprises straw pre-treatment, cutting off, batching, adhesive spraying, burden distribution, repressing, hot pressing and modular processing. The production process meets the integral idea of sustainable development, which is characterizes in the outstanding energy saving effect, the simple technology and the low cost. The material prepared has light weight, excellent environmental protection performance and outstanding water and fire proof performance. The production material has wide source, which is characterized by the high strength, good tenacity and excellent seismic behavior.

Description

technical field [0001] The invention belongs to the technical field of building wall materials, and in particular relates to a biomass composite material wall module and a processing technology thereof. Background technique [0002] Before the 1990s, 95% of building wall materials in my country were solid clay bricks. After the State Council promulgated Guofa [1992] No. 66 document on wall material innovation and building energy conservation in 1992, the research and production of new wall materials for energy-saving, land-saving, and waste-saving thermal insulation gradually developed. At this time, the wall material is mainly made of cement, fly ash, clay, magnesite and other inorganic materials through sintering or extrusion. For example, the patent application number CN93105763.9 is a representative early wall material. Production method: It is made by mixing cinder, fly ash, calcium chloride and water for curing. It can improve building functions, improve housing qual...

Problems solved by technology

However, in its production process, plant fibers need to be crushed to 100 meshes, and it takes more energy to obtain powder particles with such a small particle size, which undoubtedly increases energy consumption.

In addition, in the implementation example, the total amount of corn starch adhesive and corn starch is 50% to 80%. This amount accounts for a relatively large proportion in the entire material, which will inevitably increase the cost of the prepared material.
