Abstract
A dust inhibitor contains starch (1-7 wt.%), acrylic acid (5-20), persulfate (0.05-0.3), cross-linking agent (0.001-0.005), chelating agent (0.1-0.2) and water (rest). The advantages are low cost, high and durable dust-inhibiting effect, and no secondary pollution.
Description
The utility model relates to a kind of dust-inhibitor, particularly a kind of water-soluble polymer dust-inhibitor.
China is in Economic development period, and the capital construction project is many, and scale is big, because of construction site, exposed ground, material stockyard etc. cause that dust pollution question is serious day by day, prevent that the method for dust pollution is more, for example: traditional watering method, this method is simple, but because water evaporates is too fast, especially in the summer and autumn of sweltering heat, watering does not almost have dustproof effect, moreover, watering also can increase water rate and labor service expenditure continually, waste water resource, and the road surface is damaged; Also have to adopt and lay macadam pavement or emulsified bitumen road surface with better upper layer, spread hygroscopic salt or spill method such as industrial effluent, though the dustproof effect of these methods increases, but more or less exist cost too high, or doughnut and component had corrosive nature, perhaps cause disadvantages such as secondary pollution.
The purpose of this invention is to provide a kind of chemical dust-inhibitor, this dust-inhibitor can keep good anti-dust effect in a long time, and manufacture craft is easy, and cost is lower.
For achieving the above object, the utility model is taked following design: it is made up of this dust-inhibitor following composition, its weight percent is: starch 1-7%, vinylformic acid 5-20%, persulphate 0.05-0.3%, linking agent 0.0001-0.005%, ammonia carboxylic acids chelating agent 0.1-0.2%, all the other are water.
The present invention system utilizes Acrylic Acid Monomer and starch to carry out graft polymerization, forms high molecular weight water soluble polymer.In the prescription, persulphate is an initiator, sequestrant is ammonia carboxylic class acid position agent, disodium ethylene diamine tetraacetate for example, linking agent is an amides, adds tensio-active agent and can improve stability of solution and avidity, good penetrability, available sodium lauryl sulphate. alkyl trimethyl ammonium chloride, OP-10, tween-80.
Embodiment 1
With common starch 3kg gelatinization (according to a conventional method; in about 50-90 ℃ temperature range) be dissolved in the 86kg water, cooling adds other compositions subsequently; Acrylic Acid Monomer 10kg; anionic 0.5kg, persulphate 0.075kg, sequestrant disodium ethylene diamine tetraacetate 0.2kg, linking agent N-N methylene-bisacrylamide 0.002kg; sodium hydroxide is regulated pH value to 6-7; under nitrogen protection, 70 ℃ of isothermal reactions 3 hours, agent is inhibited.
Embodiment 2
Operation steps is with embodiment 1, and the each component consumption is starch 2kg, vinylformic acid 15kg, persulphate 0.05kg, linking agent N-N methylene-bisacrylamide 0.001kg, sequestrant disodium ethylene diamine tetraacetate 0.1kg.Regulate pH value 6-7,3 hours reaction times with sodium hydroxide.
Advantage simple process of the present invention, cost is lower, and referring to relatively can with other dust suppressants of equal anti-dust effect With long period maintenance anti-dust effect, make air quality reach 2 grades (dust concentrations), do not cause the secondary dirt Dye, do not affect crop growth.
Claims (5)
1, a kind of dust-inhibitor is characterized in that: it is formed its weight percent by following composition and is: starch 1-7%, and vinylformic acid 5-20%, persulphate 0.05-0.3%, linking agent 0.0001-0.005%, ammonia carboxylic acids chelating agent 0.1-0.2%, all the other are water.
