Abstract

A method for preparing an anticorrosion antioxidation material is disclosed. The method includes firstly adding bamboo powder into a NaOH solution containing cytosine; soaking and reacting the bamboopowder; then reacting the alkali-treated bamboo powder in an ethanol solution containing vinyltrimethoxysilane to obtain silane-modified bamboo powder; modifying and reacting alkali-treated bamboo powder in distilled water containing stearic acid and ammonium 3-bromocamphor-8-sulfonate to obtain bamboo powder modified with stearic acid; finally fully mixing the silane-modified bamboo powder, the bamboo powder modified with stearic acid, polypropylene powder and an antioxidant; and subjecting the mixture to melting and granulation to obtain the anticorrosion antioxidation material. Beneficial effects are that the method can effectively improve roughness of the surface and inside of bamboo powder, polarity of the bamboo powder is increased, the degree of crystallization of cellulose molecules is increased, mechanical meshing between the bamboo powder and a resin matrix is further improved, the density and uniformity of the composite material are improved, and mechanical strength and an antioxidation function of the material are improved.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a method for preparing a corrosion-resistant and anti-oxidation material. technical background [0002] Materials are those substances that humans use to make articles, devices, components, machines or other products. Materials are substances, but not all substances can be called materials. Such as fuels and chemical raw materials, industrial chemicals, food and pharmaceuticals are generally not considered materials. But this definition is not so strict. For example, explosives and solid rocket propellants are generally called "energetic materials" because they are part of artillery or rockets. Due to the variety, there is no unified standard for classification methods. From the perspective of physical and chemical properties, it can be divided into metal materials, inorganic non-metallic materials, organic polymer materials and composite materials composed of different typ...
