example 1

[0011] First get 900 kg of water: 20 kg of polyvinyl alcohol: 80 kg of water-soluble polymer copolymer emulsion, namely vinyl acetate-ethylene copolymer emulsion, 1 kg of sodium nitrite, 0.5 kg of sodium benzoate, and 0.4 kg of tributyl phosphate. The preparation method is as follows: : first add the above-mentioned 900 kg of water and 20 kg of polyvinyl alcohol into the reactor in sequence, heat to 95°C to dissolve all the polyvinyl alcohol, then cool down to about 40°C, and then add 80 kg of water-soluble polymer copolymerization The emulsion is vinyl acetate-ethylene copolymer emulsion, 1 kg of sodium nitrite as antirust agent, 0.5 kg of sodium benzoate as preservative, and 0.4 kg of tributyl phosphate as antifoaming agent. That is the finished product.

[0014] First take 900 kg of water: 16 kg of polyvinyl alcohol: 90 kg of water-soluble polymer copolymer emulsion, namely vinyl acetate-ethylene copolymer emulsion, 1.5 kg of borax, 0.5 kg of potassium sorbate, and 0.7 kg of octanol. The preparation method is: first The above 900 kg of water and 16 kg of polyvinyl alcohol were added to the reaction kettle in sequence, heated to 95°C to dissolve all the polyvinyl alcohol, then cooled to about 40°C, and then 90 kg of water-soluble polymer copolymer emulsion, namely acetic acid, was added in sequence. Ethylene-ethylene copolymer emulsion, 1.5 kg of borax as an antirust agent, 0.5 kg of potassium sorbate as a preservative, and 0.7 kg of octanol as a defoamer are stirred evenly, and the finished product is obtained after filtering and discharging.

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 [0001] The invention relates to the technical field of adhesives, in particular to a railway bulk granular cargo loading reinforcement adhesive used to solve environmental pollution during the transportation of solid granular materials. Background technique [0002] With the continuous development and progress of human society, people pay more and more attention to the earth environment on which human beings depend. In all production industries, the requirements for environmental protection occupy a very important position. At present, in the process of transporting goods, especially granular goods such as coal or sand, there are particle splashes and dust problems during vehicle operation, which not only poses safety hazards but also causes environmental pollution. The existing solution is to cover the vehicle with a tarpaulin or sprinkle water, but neither can effectively solve the problem. Covering the tarpaulin reduces the operating efficiency and makes r...
