However, it also causes the disadvantages of moisture absorption and water seepage. On the one hand, the plant fibers will be depolymerized by microorganisms in a water-soaked environment, which will reduce the tensile strength of the fibers; A large number of monosaccharides, oligosaccharides, lignin, etc. are proposed to cause serious retardation of cement. Therefore, it is necessary to modify the existing plant fibers to waterproof and improve the structure of the board wall so that the bone is continuous when the finished product is finished. The discontinuous structure of most of the pores ensures the solidity, waterproof and air permeability of the wall

Abstract
The invention discloses an antibacterial anti-compression thermal insulation wallboard. On the one hand, corn straw fibers are subjected to high temperature steam pretreatment, then part of pectin is removed, acetic acid is added, acetylation treatment is carried out, free hydroxide radicals in cellulose are enclosed, the hydrophobic performance and the thermal stability of the material are raised, then a waterproof agent immersion method is employed for processing, the material water absorption is lowered, the alkali corrosion resistance of the material in a cement-based material is raised and the capability of resisting microorganisms from depolymerization is raised. On the other hand, vermiculite powder, building brick garbage and the like are modified, utilized, and blended with chitosan and polyacrylamide, granulation is carried out, the intensity and the toughness of the product are raised, the product is not easy to fracture, the thermal insulation wallboard prepared according to the method is low in cost, the added modified corn straw fibers can absorb released energy when a cement-based material cracks, therefore extension of the crack in the cement-based material is stopped, namely, the toughness of the material is raised, the compression toughness index is raised, and the provided thermal insulation wallboard has characteristics of anti-bacteria, anti-compression, good endurance, water resistance, good thermal insulation performance and the like.
Description
technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to an antibacterial and pressure-resistant thermal insulation wallboard and a manufacturing method thereof. Background technique [0002] At present, external wall insulation is mainly used for external wall insulation in my country. Compared with internal insulation, it effectively reduces the "thermal bridge" of the building structure, increases the effective space of the building, eliminates condensation, and improves the comfort of living. Moreover, the external thermal insulation technology is not only applicable to new structural projects, but also to renovation projects of old buildings, with a wider scope of application and higher technical content. Currently used external wall insulation materials such as EPS, etc., whose raw materials come from petroleum. Under the environment of a sharp increase in the price of petroleum products, EPS / XPS wil...
