CN105439630A - Dammar resin sand based water permeable brick with quick water permeable speed and producing method thereof - Google Patents

Abstract

The invention discloses a Dammar resin sand based water permeable brick with a quick water permeable speed. According to the invention, cotton stalks after being carbonized is ground at room temperature, and pore surfaces adsorb nano yttrium oxide, so that the adsorbability of products is improved; by taking modified sugar filtered mud as a pore-forming agent, desert sand is washed with water and dried, and then compatible with coarse aggregates such as Taihu Lake silt, lithium feldspar, expanded perlite, and the like, so that under the condition of not affecting the water permeability of brick bodies, the strength and shock resistance of products are significantly improved; and cement is replaced with Dammar resin as a binding material, and the Dammar resin and other effective additives are interacted. The sand based water permeable brick prepared according to the invention has the excellent properties such as high strength and rapid water permeable speed and the like, and achieves the dual purpose of reutilizing Taihu Lake silt and improving the urban ecological environment.

Description

Technical field

The present invention relates to building material technical field, particularly relate to a kind of permeable fireballing dammar gum sand base water-permeable brick and preparation method thereof.

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, provides a kind of permeable fireballing dammar gum sand base water-permeable brick and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of permeable fireballing dammar gum sand base water-permeable brick, is made up of the raw material of following weight part: Desert Sand 35-37, Taihu Lake mud 20-22, lithium feldspar 11-13, pearlstone 15-16, sugared filter mud 15-17, oyster shells powder 8-9, nano yttrium oxide 0.4-0.6, W-Gum 6-8, peanut oil 5-7, dammar gum 11-13, zinc sulfate 0.6-0.8, cotton stalk 6-7, suitable quantity of water.

The making method of described a kind of permeable fireballing dammar gum sand base water-permeable brick, comprises the following steps:

(1) cotton 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 yttrium oxide, W-Gum, peanut oil grinding 40-50 minute, dry;

(2) dry after the washing of sugared filter mud at 50-60 DEG C of temperature, send in high-speed mixer and add dammar gum, zinc sulfate 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 Taihu Lake mud after Desert Sand washing being dried, lithium feldspar, pearlstone be crushed to 120-140 order after 675-720 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 cotton stalk charing processes by the present invention, pore surface absorption nano yttrium oxide, improve the adsorptivity of product, with modified sugared filter mud for pore former, compatibility Taihu Lake mud is again dried in Desert Sand washing, lithium feldspar, the coarse aggregates such as pearlstone significantly improve intensity and the fracture resistance of product when not affecting brick body water-permeable, substituting cement as binding material using dammar gum coordinates other effective auxiliary agents to interact, it is high that the sand base water-permeable brick utilizing the present invention to obtain has intensity, permeable speed waits excellent properties soon, realize the dual purpose that Taihu Lake mud recycles and improves urban ecological environment.
