Problems solved by technology
This method needs to treat the plant fiber with dilute sulfuric acid first, then wash it to neutrality, and then adjust the pH to 12-14. The intermediate process requires a high pH value, resulting in high production costs.

Abstract
The invention discloses mixed slurry for constructional engineering and a preparation method of the mixed slurry. The mixed slurry comprises 1-15 parts of heat-insulation fireproof viscose slurry, 1-5parts of gelatin, 1-2 parts of a fiber surface modifying agent, 50-200 parts of cement, 20-100 parts of water, 2-3 parts of a water repellent and 1-2 parts of a coupling agent, wherein the heat-insulation fireproof viscose slurry is prepared by mixed reaction of a water glass solution of remaining alkali liquor of reaction and plant straws. The heat-insulation fireproof viscose slurry modifies the structure of the plant straws by the remaining alkali liquor in a water glass preparation process, the utilization rate of the alkali liquor is increased, the production cost is reduced, meanwhile,the mixed slurry is fully mixed with the plant straws with a heat-insulation effect and water glass with a fireproof effect, and thus, the final mixed slurry for constructional engineering has good heat-insulation and fireproof effect.
Description
technical field [0001] The invention belongs to the field of building materials, in particular to the field of building thermal insulation materials, and more specifically to a green building material with thermal insulation effect. Background technique [0002] Building energy consumption occupies a considerable proportion in both industrially developed countries and developing countries, so building energy conservation is a common issue faced by human society. It is predicted that by about 2030, my country's building energy consumption will account for 30%-40% of the total energy consumption, becoming the world's largest energy consumer. In this form, the country's requirements for building energy conservation are becoming increasingly urgent. Strengthening research and development and popularizing the application of new energy-saving and environmentally friendly materials in the construction field is an important reality for improving my country's resource utilization rat...
