Abstract

The invention discloses a preparation method and application of a building material. The method includes the steps of stirring diatomite, dolomite powder and calcium hypophosphite to obtain a primarymixture, then making the primary mixture subjected to grinding and screening and adding polyacrylate emulsion, polyhexamethylene biguanidine hydrochloride and sodium polystyrenesulfonate; raising thetemperature for stirring to obtain a secondary mixture, then adding dimethylformamide with the weight 15 times that of the secondary mixture, and adding a maleic anhydride grafting compatilizer afterstirring; introducing inert gas, stirring the mixture at the constant temperature of 50 DEG C, conveying the mixture into a drying box for complete drying, and discharging the material for cooling toobtain a modified mixture; transferring the modified mixture into a high-pressure reaction kettle for a hydrothermal reaction, introducing the product of the hydrothermal reaction into a double-screwextruder, conducting extrusion and pelleting and then obtaining a finished product of the building material. The prepared building material is high in strength and light in weight and has a great application prospect in architectural engineering.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method and application of building materials. Background technique [0002] The materials used in buildings are collectively referred to as building materials, which is a general term for materials used in civil engineering and construction engineering. Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include: wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, composite materials, etc.; decorative materials include: various coatings, paints, coatings, veneers, tiles of various colors, special Effect glass, etc.; special materials refer to: used for waterproof, moisture-proof, anti-corrosion, fire prevention, flame retardant, sound insulation, heat insulation, heat preservation, sealing, etc. [0003] Concrete is the most widely use...
