Embodiment 1

[0024] A preparation method of a novel compression-resistant building material, comprising the following preparation steps:

[0025] 1. Mix and stir fly ash, polymer, coagulation-accelerating material and water to obtain mixture 1;

[0026] 2. When the straw is dried at 80°C until the water content is below 5%, it is introduced into a grinder and ground to pass through a 200-mesh sieve to obtain straw powder;

[0027] 3. Mix calcium magnesium carbonate, blast furnace slag, clay, dolomite powder, feldspar powder and calcium borate in a ball mill for ball milling. The ball-to-material ratio in the ball mill is 12:1, and the ball milling time is 50 minutes to obtain mixture 2;

[0028] 4. Add straw powder and mixture 2 to mixture 1 in sequence, then add hydroxypropyl methylcellulose and butyl rubber, stir while heating, the temperature is 380°C, stir for 45 minutes, and obtain the base material;

[0029] 5. The base material is introduced into the mold and pressurized to form th...

Abstract

The invention discloses a method for preparing a novel pressure-resistant building material. The method comprises the following steps: I, mixing and uniformly stirring coal ash, a polymer, a coagulating material and water so as to obtain a mixture I; II, drying straw at 80-100 DEG C till the moisture is less than 5%, grinding in a grinding machine, and screening till the particle size is 200-300 meshes so as to obtain straw powder; III, performing ball-milling on magnesium calcium carbonate, blast furnace slag, clay, dolomite dust, feldspar powder and calcium borate in a ball-milling machine so as to obtain a mixture II, wherein the ratio of a milling media to materials is (12:1)-(20:1) in the ball-milling machine; and the ball-milling time is 50-60 minutes; IV, sequentially putting the straw powder and the mixture II into the mixture I, further adding hydroxypropyl methyl cellulose and butyl rubber, and heating and stirring at 300-380 DEG C for 40-45 minutes so as to obtain a base material; and V, introducing the base material into a mold, and performing pressurizing molding, thereby obtaining a finished product. The building material prepared by using the method has the characteristics of being high in breaking strength and high in pressure resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a novel compression-resistant building material. Background technique [0002] New building materials mainly include five parts: new wall materials, new building coatings, new building plastics, new building decoration materials, and new waterproof and sealing materials. New wall building materials refer to new material resources, low energy consumption, large use of local resources and waste resources; friendly to the environment, people, harmless and conducive to ecological environment protection, maintaining the balance of the ecological environment; at the same time, they can be recycled. New building materials currently have the characteristics of light weight and high strength: light weight mainly means that the material is porous and has a small volume density. High strength mainly refers to the high strength of the material....
