A kind of modified biomass building wall material

Abstract

The invention discloses a modified biomass building wall material, which comprises the following components by mass percentage: 28-70% of biomass material, 10-40% of cement, 10-30% of gypsum powder, and 10-30% of fine sand , lightweight aggregate 5‑20%, waterproof rubber powder 0.01‑0.04%, water reducing agent 0.01‑0.03%, waterproofing agent 0.02‑0.05%, methyl cellulose 0.005‑0.01%, plant phospholipase 0.03‑0.06%, wood 0.03‑0.06% of fiber, 0.01‑0.03% of polyvinylamide, and 0.02‑0.04% of biomass antifungal agent. In the present invention, all raw materials are put into the assembly line after being allocated in a reasonable proportion. The production process is completed in one go, and the production efficiency is high. In the production process The biomass material is modified first to avoid the problems of demoulding adhesion and rebound after demoulding, adding biological antifungal agent and water repellent, which will not affect the durability of the finished material due to the high specific gravity of the biomass material. Realized the same life as the building.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a modified biomass building wall material. Background technique [0002] Every year during summer harvest and autumn and winter, a large amount of wheat, corn and other stalks are always burned in the fields, producing a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit that affects the urban environment. According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, which has become "waste" that is "not very useful" but must be disposed of. In this case, it is completely handled by farmers, and a large number of them will be burned and buried in farmland, which will not achieve the value of recycling. [0003] At present, my country's "urbanization" process is rapid, and the consumption of building materials is ...

Problems solved by technology

[0003] At present, my country's "urbanization" process is rapid, and the consumption of building materials is also increasing day by day. At present, straw is used as raw material in building materials. However, due to the good toughness and expansion of biomass materials, after compaction, the internal There are still gaps and even the situation that the plate is difficult to condense and cannot be separated from the mold immediately. This can only reduce the proportion of biomass materials and occupy a large number of molds for a long time. It can only be based on laboratory data, and it is difficult to achieve large-scale production. Practical to the market
