Problems solved by technology

However, the surfactant technology characterized by room temperature foaming usually produces closed pores, which cannot meet the requirements of porous through-holes for water storage materials; while materials characterized by high-temperature sintered foaming usually have low porosity (generally low less than 50%), and poor porosity uniformity

Embodiment 1

[0022] Prepare a kind of high-performance water storage material, raw material and mass percent composition are: 50% river course silt (in terms of solid content, wherein silicate and aluminate total content accounts for 74%), 45.75% rice straw (burning loss Amount 50%), 3% potassium feldspar (average particle size 0.5mm), 1% calcium carbonate, 0.25% cellulose ether. The preparation process is as follows: Grind the river silt to a particle size of 40-60 μm, crush the rice straw to a length of <2 cm, and then mix all the materials according to the proportion, and place them in a ball forming machine to form a round or oval shape with a particle size of 2 cm. The particles were then dried at 100°C and sintered at 850°C for 20min to obtain a water storage material.

[0023] After testing, the solid waste consumption of the water storage material prepared in this embodiment reaches 95.25%, and the density is 80Kg / m 3 , the water storage rate is 105%, the cylinder compressive stre...

Embodiment 2

[0025] Prepare a kind of high-performance water storage material, raw material and mass percentage are made up of: 80% river course silt (in terms of solid content, wherein silicate and aluminate total content accounts for 50%), 15.75% corn stalks (burning loss 75%), 3% potassium feldspar (average particle size 0.1mm), 1% calcium carbonate, 0.25% cellulose ether. The preparation process is as follows: grind the river sludge until the particle size is 50-80 μm, crush the corn stalks until the length is less than 2 cm, then mix all the materials according to the proportion, put them in a ball forming machine and shape them into a round or oval shape with a particle size of 5 cm The particles were then dried at 100°C and sintered at 850°C for 30min to obtain a water storage material.

[0026] After testing, the solid waste consumption of the water storage material prepared in this embodiment reaches 95.25%, and the density is 200Kg / m 3 , the water storage rate is 80%, the cylind...

Embodiment 3

[0028] Prepare a kind of high-performance water storage material, raw material and mass percentage are composed of: 60% shale (in terms of solid content, wherein the total content of silicate and aluminate accounts for 80%), 38% peanut straw (burning loss 90%), 1% potassium feldspar (average particle size 0.2mm), 1% calcium carbonate. The preparation process is as follows: grind the shale until the particle size is 40-100 μm, crush the peanut stalks until the length is less than 2cm, then fully mix all the materials according to the proportion, put them in a ball forming machine and shape them into a circle or ellipse with a particle size of 4cm shaped particles, followed by drying at 50°C and sintering at 900°C for 15 minutes to obtain a water storage material.

[0029] After testing, the density of the water storage material prepared in this embodiment is 150Kg / m 3 , the water storage rate is 95%, the cylinder compressive strength is 1.1MPa, and the softening coefficient is...

Abstract

The invention relates to a high-performance water storage material and a preparation method thereof. The water storage material is prepared from, by weight, 46.75-80% of a clay raw material (by solid), 15.75-50% of a biomass raw material, 0.5-3% of a high temperature liquid phase promoter, 0-1% of a high temperature foaming agent and 0-0.25% of a plasticizer. The preparation method comprises the following steps: weighing the clay raw material containing silicate and aluminate, the biomass raw material, the high temperature liquid phase promoter, the high temperature foaming agent and the plasticizer according to the above mass proportions, fully and uniformly stirring the weighed raw materials, placing the obtained mixture in a granulator, molding circular or elliptical granules with the particle sizes being 2-5 cm, and drying and sintering the granules to obtain the water storage material. The high-performance water storage material obtained through optimizing and combining in variousfoaming modes has a good water storage performance, and has a water storage rate reaching 80-105%.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-performance water storage material and a preparation method thereof. Background technique [0002] Using measures such as infiltration, stagnation, storage, purification, utilization, and drainage to absorb and utilize 70% of the rainfall locally is the main method for developing sponge cities at present. Sponge city is a new generation of urban rain and flood management concept, which means that when it rains, the city absorbs, stores, infiltrates and purifies water, and "releases" the stored water and uses it when needed. [0003] In the process of sponge city construction, building materials with water absorption, water storage, water seepage and water purification functions are the key to the realization of sponge city construction. At present, the materials for sponge city construction are mainly permeable materials. The main requirements are water perme...
