Embodiment 1

[0024] The preparation process is as follows:

[0025] (1) The quartz sand dust is collected by the filter dust collector and collected in the dust collector; wherein, the inner wall of the dust collector is coated with 300g / L aminocellulose, 360g / L paraffin powder, 120g / L macroporous Silica gel, 220g / L bentonite is composed of a composite layer with a thickness of 0.8 to 1 cm. When preparing the coating solution for the composite layer, dissolve or disperse each component in an acetone solution with a volume fraction of 85%. At the same time, the dust collector A heating device is installed;

[0026] (2) When the volume of quartz sand dust collected in the dust collector reaches 1 / 2 of the volume of the dust collector, turn on the heating device of the dust collector and set the temperature at 70°C; the composite layer in step (1) It is heated and dissolved, and mixed with the quartz sand dust collected in the dust collector to form a cloudy liquid;

[0027] (3) Turn off th...

Embodiment 2

[0030] The preparation process is as follows:

[0031] The time of opening the dust collector heating device in the embodiment 1 step (2) is delayed to be when the quartz sand dust volume reaches 3 / 5 of the dust collector volume, and all the other preparation methods are also the same as embodiment 1.

Abstract

The invention discloses a method for preparing polymer cement waterproof mortar from quartz sand dust. The method includes: pretreating a quartz sand dust collector by composite coating liquid composed of amino cellulose, paraffin powder, macroporous silica gel and bentonite to form a composite layer of the dust collector; heating to melt the composite layer, mixing with quartz sand dust in the dust collector to form turbid liquid, and adopting the turbid liquid for successfully preparing the polymer cement waterproof mortar. The method for preparing the polymer cement waterproof mortar from the quartz sand dust is simple in operation and environmentally friendly and makes full use of the waste quartz sand dust, and high-attached-value chemical products are obtained while secondary dust pollution is avoided.

Description

technical field [0001] The invention relates to the field of quartz sand dust recovery, in particular to a method for preparing polymer cement waterproof mortar by using quartz sand dust. Background technique [0002] my country has extremely rich vein quartz mineral resources. Quartz sand and related products can be obtained through its mining, preliminary processing, purification and refining. The manufacturing and processing of quartz sand is also an important part of the non-metallic mineral product processing industry. Quartz sand has excellent chemical and physical properties such as high hardness, high temperature resistance, small thermal expansion coefficient, high insulation, pressure resistance, and corrosion resistance. It is widely used in traditional industries (such as glass industry, building materials industry, chemical industry, etc.) and high-tech industries. (Such as aerospace, optical cable communication, solar energy conversion, etc.). [0003] With th...
