Abstract

The invention relates to a preparation method of a high-strength stamping-resistant and fireproof building material, and belongs to the technical field of building materials. The preparation method comprises the following steps: firstly pulverizing and mixing straws and log wood blocks, feeding the mixture and water into a reaction kettle, dropwise adding citric acid to obtain an acidic solution,then adding ferric chloride, stirring at a high temperature, then performing high temperature and high pressure reaction to obtain heat treatment reaction liquid, dropwise adding an alkali solution into the heat treatment reaction solution, then adding silicon dioxide for reaction to obtain reaction slurry, adding copper powder into the reaction slurry, shaking for a reaction, then adding sulfuricacid and stirring after the reaction, filtering the mixture to obtain a self-made fiber product, and finally, mixing the self-made fiber product with clay, perlite and other raw materials, then mixing the mixture with resin, feeding into an extruder for extrusion, and performing hot pressing and discharging to obtain the high-strength stamping-resistant and fireproof building material. The fiberis modified, so that the high-temperature-resistance, the flame retardant property and the mechanical strength of the fiber are improved, and the mechanical properties and the flame retardant strengthof the building material are enhanced; the preparation method has a good application prospect.

Description

technical field [0001] The invention relates to a preparation method of a high-strength stamping-resistant fireproof building material, which belongs to the technical field of building materials. Background technique [0002] In recent decades, with the rapid growth of urban population and the limitation of geographical scale, civil buildings have developed rapidly, and a large number of high-rise and multi-storey buildings have sprung up. Because of the continuous development of civil engineering, the use of building materials is increasing, resulting in a serious environmental burden. [0003] From a macro point of view, China's development of ecological building materials should focus on introducing resources and environmental awareness at this stage, adopting high-tech to carry out environmental coordination transformation of the dominant traditional building materials, and improving the waste of resources and energy in the building materials industry as soon as possible...
