Embodiment Construction

[0024] In parts by weight, weigh 3 to 5 parts of metasequoia bark, 7 to 9 parts of reed bamboo poles, 6 to 8 parts of umbrella grass leaves and 3 to 5 parts of red maple bark and put them into a planetary ball mill. Mix and grind for 2-3 hours under the condition of ~100r / min to obtain the mixed product; put the mixed product in a steam explosion tank, and send water vapor at a temperature of 260-300°C to the steam explosion tank until the pressure in the steam explosion tank rises As high as 3-4MPa, seal the mouth of the tank, let it stand at constant temperature and pressure for 30-40 minutes, open the mouth of the tank after standing to obtain the steam explosion product; mix the above steam explosion product with the sulfuric acid solution with a mass fraction of 40-50% in a mass ratio of 1 : 10 drops into the beaker, mixes and stirs 30~40min with the rotating speed of 500~600r / min with agitator and makes mixed slurry, drops into the acetic acid solution that the mass fract...

Abstract

The invention relates to a preparation method for a waterproof and heat-insulating self-leveling material, belonging to the technical field of building materials. According to the invention, Metasequoia glyptostroboides barks, nalgrass poles, Cyperus alternifolius leaves and red maple barks are mixed and ground; water molecules are pressed into tissue fibers at a high temperature and a high pressure; sodium ferrate oxidized lignin is added to generate carboxyl groups with hydroxyl groups on cellulose; meanwhile, ester groups have good heat-insulating performance and facilitate reinforcing hydrophobicity of a self-leveling material; modified and decomposed plant fibers are mixed with glucose for a reaction, and the glucose has rich hydroxyl groups which can react with the plant fibers withsurface grafted with a large number of carboxyl groups to form stable covalent bond adsorption; through a granular structure, the self-leveling material forms a plurality of micropores in a microstructure after construction curing, and gas is filled in pores to facilitate reinforcing the heat-insulating performance of the self-leveling material; thus, the self-leveling material has broad application prospects.

Description

technical field [0001] The invention relates to a preparation method of a waterproof and heat-insulating self-leveling material, which belongs to the technical field of building materials. Background technique [0002] Self-leveling is a solvent-free, self-leveling, high-build epoxy floor coating with dense particles. Self-leveling solves the six major problems in floor installation. It is a ground construction technology. It is a liquid substance mixed with multiple materials and water. After being poured into the ground, this substance can flow along the ground according to the unevenness of the ground to automatically level the ground. The self-leveling floor engineering surface coating is beautiful, high cleanliness, high wear resistance and load-bearing, the most important thing is the beautiful decorative effect, because the first reaction of people's vision is the color and effect of the surface. The quality disadvantages of self-leveling floor engineering surface c...
