Embodiment 1

[0007] The fatty acid ammonium solution is prepared according to the fatty acid:water:ammonium water weight ratio of 1:25:0.5. 1 kg of fatty acid ammonium solution with a fineness of more than 80 meshes is fully stirred until it becomes a paste, then the stirring is stopped, and the waterproof powder is obtained by drying.

Embodiment 2

[0009] Mix 15 kg of furnace ash with a fineness of more than 100 mesh and 20 kg of calcium hydroxide evenly, then add 35 kg of fatty acid ammonium solution prepared according to the ratio provided in Example 1 and stir fully, stop stirring after it becomes paste, and dry , to produce waterproof powder.

Embodiment 3

[0011] Mix 200 kilograms of pulverized coal with 200 kilograms of calcium hydroxide with a fineness of more than 100 mesh, then add 400 kilograms of fatty acid ammonium solution prepared according to the ratio provided in Example 1 and stir fully, stop stirring after it becomes paste, and dry , to produce waterproof powder.

Abstract

The present invention relates to waterproof powder producing process. The waterproof powder consists of basic grains with sintered industrial slag as core and calcium stearate as coating. The production process includes mixing sintered industrial slag with calcium hydroxide homogeneously; adding ammonium stearate solution via stirring to form paste; and stoving to obtain the waterproof powder. The present invention has the advantages of firm structure, less influence of outer humidity and temperature, stable performance, powerful waterproof performance, light weight, and low cost.

Description

technical field [0001] The invention belongs to a production method of powdery waterproof material for construction. Background technique [0002] At present, there are various types of waterproof materials used in construction projects, such as waterproof ointment, coiled material, and sheet material. Its disadvantage is that the preparation is complicated, and the performance and price are not ideal. In recent years, with the advent of powdery waterproof materials, the cost of raw materials is high and consumes more energy. At the same time, certain equipment and large-area sites are required to increase the cost. Contents of the invention [0003] The invention provides a production method of waterproof powder, which solves the problems of high cost and energy consumption in the prior art. Technical solution: The basic particles of waterproofing are based on the fine particles of industrial sintering waste slag. Since the surface of the fine particles of industrial si...
