Embodiment 1

[0026] A waterproofing agent for the surface of briquette, the components and the content of each component are: a variety of vitriol in equal mass ratio, including: potassium dichromate, potassium aluminum sulfate, copper sulfate, potassium chromium sulfate, 1 part each, 300 parts of water glass, 50 parts of water.

[0027] The preparation method of the waterproofing agent: heat 50 parts of water to 95-100℃, then add various kinds of alum simultaneously, stir to dissolve it completely, let it stand and cool to 40-55℃; finally add 300 parts of water glass, stir The water repellent is prepared until the color of the mixed solution is consistent, and the stirring time is 20-40 min.

[0028] The performance test of the briquette prepared by using the waterproofing agent in Example 1 is as follows: the briquette produced by using the waterproofing agent of this embodiment according to Process 1, the mass fraction of the absorbed waterproofing agent is 2.9%, and the thickness of th...

Embodiment 2

[0030] A waterproofing agent for the surface of briquette, the components and the content of each component are: a variety of vitriol in equal mass ratio, including: potassium dichromate, potassium aluminum sulfate, copper sulfate, potassium chromium sulfate, 2 parts each, 400 parts of water glass, 60 parts of water.

[0031] Preparation method of waterproofing agent: heat 60 parts of water to 95-100℃, then add various kinds of alum at the same time, stir to dissolve it completely, let it stand for natural cooling to 40-55℃; finally add 400 parts of water glass, stir The water repellent is prepared until the color of the mixed solution is consistent, and the stirring time is 20-40 min.

[0032] The performance test data of the briquette prepared by using the water repellent in Example 2 are shown in Table 1.

Embodiment 3

[0034] A waterproofing agent for the surface of briquette, the components and the content of each component are: a variety of vitriol in equal mass ratio, including: potassium dichromate, potassium aluminum sulfate, copper sulfate, potassium chromium sulfate, 3 parts each, 500 parts of water glass, 70 parts of water.

[0035] The preparation method of the waterproofing agent: heat 70 parts of water to 95-100℃, then add various kinds of alum simultaneously, stir to dissolve it completely, let it stand for natural cooling to 40-55℃; finally add 500 parts of water glass, stir The water repellent is prepared until the color of the mixed solution is consistent, and the stirring time is 20-40 min.

[0036] Table 1 shows the performance test data of the briquette prepared by using the water repellent in Example 3.

Abstract

The invention relates to a waterproof agent used on briquette surface and a preparation method thereof, and a waterproof briquette and a manufacturing method thereof. The waterproof agent comprises, by weight, 1-3 parts of potassium dichromate, 1-3 parts of potassium aluminum sulfate, 1-3 parts of copper sulfate, and 1-3 parts of potassium chromium sulfate with equal mass proportions, and 300-500 parts of water glass and 50-70 parts of water. According to the invention, the 50-70 parts by weight of water is heated to 95-100 DEG C; various alums are added, and are completely dissolved by stirring; the material is subjected to standing, and is naturally cooled to 40-55 DEG C; 300-500 parts by weight of the water glass is added; and the mixture is stirred for 20-40min, such that the waterproofing agent is obtained. Briquette is soaked in the waterproofing agent for a certain period of time, and is air-dried, such that waterproof briquette is obtained. The waterproof briquette provided by the invention has the advantages of small additive dose, good waterproof performance, easy transportation, and easy storage.

Description

technical field [0001] The invention relates to the field of waterproofing, in particular to a waterproofing agent for briquette surface, a briquette waterproofing process and a waterproof briquette. Background technique [0002] In order to make full use of coal resources, pulverized coal is advocated to replace lump coal with briquette. However, the briquette will be crushed when wet and water, and the water resistance is poor, which is inconvenient for transportation and storage. At present, the common solution is to add a binder to pulverized coal, with water glass as the main body, and then mix with auxiliary materials and water to make a binder, and use the binder to blend with pulverized coal to make briquette. The preparation process is complicated, and the amount of binder added in the prepared briquette is large due to blending with pulverized coal. This process cannot achieve the waterproof function of the formed coal briquette. SUMMARY OF THE INVENTION [00...
