Abstract
The present invention relates to a granule binder which is used to prevent the transported solid granular materials from splashing and flying to pollute environment. The technical point is that a certain amount of polyvinyl alcohol and vinyl acetate-ethylene copolymer emulsion are uniformly dissolved into water to prepare the granule binder. After a layer of granule binder is sprayed on the surface of granular freight, a bound and cured layer with the thickness between 5mm and 20mm, which is characterized by high strength, good toughness and showering resistance, is formed on the surface of the granular freight, like a layer of liquid tarpaulin covering the granular freight. The amount of the sprayed granule binder is only 1kg/per square meter to 2kg/per square meter, but if the dosage isincreased, the effect is better, and the cost is low, so the granule binder is suitably promoted. In particular, the granule binder resolves the problems of a great deal of wasted energy and environment pollution, which are caused due to flying dust and sprinkled granules in the process of coal transportation. Since the domestic annual quantities of transported coal and minerals are large, the granule binder has a wide application range in terms of transportation and piling of coal and minerals, dust and sand prevention, etc.
Description
Technical field
The present invention relates to a kind of adhesive technology field, specifically a kind of railway bulk granular goods loading and reinforcing binding agent that is used for solving the environmental pollution of solid particle material transportation.
Background technology
Along with the continuous development and progress of human society, people more and more pay attention to the global environment that the mankind depend on for existence, in all production industries, requirement on environmental protection are all occupied considerable position.At present, in transportation goods process, particularly, in vehicle operating, exist particle to splash and the airborne dust problem, both existed potential safety hazard also to cause environmental pollution as particle goods such as coal or sandstone.Existing terms of settlement is to cover paulin or watering on vehicle, but all can not effectively deal with problems, and covers paulin and reduces operating efficiency, reclaims difficulty; Watering can only be prevented dust the short period of time, does not have dustproof and anti-splash effect for long distance, long-time transportation of cargo.
Summary of the invention
The purpose of this invention is to provide a kind of be used for solving at solid particle material transportation particle splash and airborne dust and cause the railway bulk granular goods loading and reinforcing binding agent of environmental pollution.
The object of the present invention is achieved like this: it is characterized in that: chemical ingredients that the present invention contains and ratio of weight and number are: 0.5～10 part of polyvinyl alcohol, and acetic acid second is rare-1～20 part of ethylene copolymerization emulsions, 70～98.5 parts in water.
As required, in aforesaid granule agglomerant, add the rust-preventive agent of 0.05～2.0 parts by weight, with solve the present invention when depositing with the ironware container corrosion and in use to the corrosion problem of metal construction.Rust-preventive agent can be selected for use: Sodium Nitrite or borax.
As required, in aforesaid granule agglomerant, add the sanitas of 0.01～1.0 parts by weight, with the preservation that solves finished product of the present invention and work-ing life problem.If long-term storage, the water in the aqueous solution can be corrupt.Sanitas can be selected for use: Whitfield's ointment, Sodium Benzoate or potassium sorbate
For the foam that suppresses finished product of the present invention produces, and reduce use viscosity of the present invention, then add the defoamer of trace, as: octanol or tributyl phosphate.
The invention has the advantages that: by at particle goods surface sprinkling one deck granule agglomerant; form the adhesive solidification layer of 5-20mm on particle goods surface; the cured layer intensity height, good toughness, the water-fast pouring that form are equivalent to cover one deck liquid paulin on the particle goods.This granule agglomerant sprinkling amount is 1-2kg/ square metre and gets final product, and is with low cost as increasing the consumption better effects if, is fit to promote.The airborne dust and the particle that have particularly solved Coal Transport are shed a large amount of wastes and the problem of environmental pollution that causes the energy, coal, the ore traffic capacity in China every year are very big, the use of granule agglomerant is in coal, ore transportation, and aspects such as coal, the dustproof sand prevention of ore stacking are with a wide range of applications.
To be described in further detail the present invention by example below, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
Embodiment
Example 1:
900 kilograms of water intakings earlier: 20 kilograms of polyvinyl alcohol: the water-soluble polymer copolymer emulsion be acetic acid second rare-80 kilograms of ethylene copolymerization emulsions, 1 kilogram of Sodium Nitrite, 0.5 kilogram of Sodium Benzoate, 0.4 kilogram of tributyl phosphate, its preparation method is: earlier with 900 above-mentioned kg water, 20 kilograms of polyvinyl alcohol add in the reactor successively, be heated to 95 ℃, after polyvinyl alcohol is all dissolved, be cooled to about 40 ℃, the water-soluble polymer copolymer emulsion that adds 80 kilograms more successively be acetic acid second rare-ethylene copolymerization emulsions, as 1 kilogram of the Sodium Nitrite of rust-preventive agent, as 0.5 kilogram of the Sodium Benzoate of sanitas and as 0.4 kilogram of the tributyl phosphate of defoamer, after stir, filtering discharging, be finished product.
Use is in the transportation of railway electricity coal, after the entrucking of colliery, adopt automatic spraying device, evenly spray every square metre of granule agglomerant that sprays about 1.5kg of coal upper surface, wind speed 23 meter per seconds in the train operation, move 28 hours, 800 kilometers of strokes, the back coal surface adhesion cured layer that arrives at a station is intact, 5-20mm behind the cured layer, do not ftracture in the surface, dust suppression splashproof effect is remarkable in the transportation.
Example 2:
900 kilograms of water intakings earlier: 16 kilograms of polyvinyl alcohol: the water-soluble polymer copolymer emulsion be acetic acid second rare-90 kilograms of ethylene copolymerization emulsions, 1.5 kilograms of boraxs, 0.5 kilogram of potassium sorbate, 0.7 kilogram of octanol, its preparation method is: earlier with 900 above-mentioned kg water, 16 kilograms of polyvinyl alcohol add in the reactor successively, be heated to 95 ℃, after polyvinyl alcohol is all dissolved, be cooled to about 40 ℃, the water-soluble polymer copolymer emulsion that adds 90 kilograms more successively be acetic acid second rare-ethylene copolymerization emulsions, as 1.5 kilograms of the boraxs of rust-preventive agent, as 0.5 kilogram of the potassium sorbate of sanitas and as 0.7 kilogram of the octanol of defoamer, after stir, filtering discharging, be finished product.
Use in the highway Coal Transport, after the entrucking at every square metre of granule agglomerant that sprays about 2kg of the upper surface of coal, 5 grades of wind-force, with per hour 80 kilometers speed operation, 1300 kilometers of strokes, arrive the point of destination after coal surface cure layer intact.
