Embodiment 1

[0012] Embodiment 1: For muddy roads and fields.

[0013] Take 1.0 kg of carboxymethyl starch, 0.5 kg of sodium silicate, and 0.5 kg of glycerol, add them into 98 kg of water, and stir thoroughly at room temperature for 15-20 minutes to prepare 100 kg of dust suppressant. In the dust suppressant, the content of carboxymethyl starch is 1%, sodium silicate is 0.5%, glycerol is 0.5%, and water is 98%. As with most solubles, appropriate warming will speed up dissolution. At the same time, pre-soaking will help shorten the stirring time required for dissolution without affecting its performance. In order to reduce the stirring time, it can also be stirred into a high-concentration solution first, and then diluted with water to the required ratio. After the dust suppressant is completely dissolved, the preparation of the dust suppressant is completed. At this point, the prepared dust suppressant can be filled into sprinkler trucks or other spraying equipment for spraying.

Embodiment 2

[0014] Embodiment 2: for streets and cement roads.

[0015] Take 0.2 kg of carboxymethyl starch, 0.5 kg of sodium silicate, and 0.1 kg of glycerin, add them into 99.2 kg of water, and stir thoroughly at room temperature for 15-20 minutes to prepare 100 kg of dust suppressant. In the dust suppressant, the content of carboxymethyl starch is 0.2%, sodium silicate is 0.5%, glycerol is 0.1%, and water is 99.2%. Others are the same as embodiment 1.

Embodiment 3

[0016] Embodiment 3: For indoor cement floor and cladding.

[0017] Take 0.1 kg of carboxymethyl starch, 0.2 kg of sodium bicarbonate, and 0.1 kg of glycerin, add them into 99.6 kg of water, and fully stir at room temperature for 15-20 minutes to prepare 100 kg of dust suppressant. In the dust suppressant, the content of carboxymethyl starch is 0.1%, sodium bicarbonate is 0.2%, glycerol is 0.1%, and water is 99.6%. Others are the same as embodiment 1.

Abstract

The ecological road dust inhibitor is solution comprising carboxymethyl starch 0.10-3.00 %, sodium silicate 0.01-2.50 % and propanetriol 0.01-2.00 %. Before being used, the three components are dissolved in water through stirring. The present invention has the combined effects of coagulation, moisture absorption and water maintenance to produce dust inhibiting. It has no toxic side effect and corrosion and can be degraded naturally after its dust inhibiting period, can improve water and soil environment and produce no pollution. It is suitable for inhibiting dust in mine road as well as city road, square, building site, etc.

Description

Technical field: [0001] The invention relates to a dust suppressant mainly used for road dust control, which can be used for dust control on mine road surfaces, production sites, urban road squares and the like. Background technique: [0002] At present, in addition to sprinkling dust (including sprinkling, spraying, ultrasonic and electrostatic water), common dust suppression techniques at home and abroad also include spraying wetting agents, solid / liquid hygroscopic agents, sticky dust agents, high-power water-absorbing resins, and composite dust suppression Several kinds of dust agents. China, the United States, Japan, Germany, Russia, Australia and other countries have all carried out research on dust suppressants. In recent years, with the development of polymer fine chemical technology, progress has been made in superabsorbents. However, there are also disadvantages such as single function or high price or toxicological properties, corrosion, refractory degradation a...
