Abstract

The invention discloses a sand-base water permeable brick inlayed with nano-silica powder. According to the sand-base water permeable brick, wheat straws are ground at the room temperature after being carbonized, and pore surfaces are adsorbed with nano-silica powder and PVA fibers, so that the adsorbability and the acid-base corrosion resistance of the product are improved; modified sugar filter mud is taken as a pore-forming agent, and desert sand is washed, dried and compounded with coarse aggregates such as barite and sulfur residue, so that the strength and the bending resistance of the product are obviously improved without influencing the water permeability of a brick body; the prepared sand-base water permeable brick has the advantages that the process is simple, the production cost is low, the porosity is high, the effects of thermal insulation, water permeation and air permeation are good, and the mechanical strength is high; the sand-base water permeable brick is a novel environment-friendly low-carbon material.

Background technology

Sand base water-permeable brick became the focus of attention in the last few years, this sand base water-permeable brick, for raw material with the sand in desert, water permeability is good, anti-skidding, also unlike water-permeable brick is easy is like that blocked by dust, but cost is too high, promoting sand base water-permeable brick is the effective way realizing Desert Sand resource utilization, on the one hand when ore resource is day by day in short supply, can using the construction timber of Desert Sand as a kind of cheapness, on the other hand for the large-area desertification control of China, to turn waste into wealth in desert be useful.But less about the research of sand base water-permeable brick at present, the industry standard that the production technique of traditional sand base water-permeable brick is backward, cost is high, function singleness, ultimate compression strength and water permeability can not reach water-permeable brick simultaneously.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, sand base water-permeable brick providing a kind of embedding nano silicon powder and preparation method thereof.

The present invention is achieved by the following technical solutions:

A sand base water-permeable brick for embedding nano silicon powder, is made up of the raw material of following weight part: Desert Sand 33-35, barite 20-21, sulfur residue 16-18, rosin rock dust 11-12, sugared filter mud 16-18, cement 5-7, PVA fiber 4-6, calcium chloride 0.5-0.7, nickel oxide 0.7-0.9, nano silicon micronization 0.2-0.4, Paraffin liquid heavy 6-8, wheat stalk 5-6, suitable quantity of water.

The making method of the sand base water-permeable brick of described a kind of embedding nano silicon powder, comprises the following steps:

(1) wheat stalk oven dry is put into charring furnace at the temperature of 450-500 DEG C, isolated air charing 20-30 minute, be cooled to room temperature and add nano silicon micronization, PVA fiber grinding 40-50 minute;

(2) dry after calcium silicate slag, the washing of sugared filter mud at 50-60 DEG C of temperature, send in high-speed mixer and add calcium chloride, nickel oxide, Paraffin liquid heavy and appropriate water, turn/speed high-speed stirring the 15-20 minute of min with 1400-1500, dry, ultrasonic grinding becomes powder to dry;

(3) add barite after Desert Sand washing being dried, sulfur residue is crushed to 120-140 order after 715-825 DEG C of high-temperature calcination process, add the mixing of step (1), (2) material and other remaining components, drop into ball milling 2-3 hour in ball mill, water spray granulation, ageing were pressed into raw adobe after 2 days;

(4) adobe natural drying will be given birth to air-dry, in 1060-1100 DEG C of sintering 1-2 hour in chamber type electric resistance furnace, naturally cool to room temperature discharging.

Advantage of the present invention is: through grinding at room temperature after wheat stalk charing processes by the present invention, pore surface absorption nano silicon micronization, PVA fiber, improve adsorptivity and the acid-alkali-corrosive-resisting of product, with modified sugared filter mud for pore former, compatibility barite is again dried in Desert Sand washing, the coarse aggregates such as sulfur residue significantly improve intensity and the fracture resistance of product when not affecting brick body water-permeable, not only technique is simple for the sand base water-permeable brick utilizing the present invention to obtain, production cost is low, and it is high to have porosity, thermal insulation permeable air permeable effect is good, the advantage that physical strength is high, it is a kind of novel environment friendly low carbon materials.
