Abstract
The invention discloses a dust suppressing agent used for powder material, which comprises 0.1-0.7 percent of water soluble polyacrylic ester expressed by the general formula, 0.2-0.5 percent of polyacrylamide, 0.15-1.5 percent of polyacrylate sodium, 0.5-1.5 percent of surface active agent and 77-99 percent of water, wherein R1, R2, and R3 in the water soluble polyacrylic ester are OH, NH2, ONa, NHC(CH3)2CH2SO3H, or alkoxyl containing 2-12 carbon, the molecular weight is 1-40 millions, and the free radical polyreaction is performed for acrylic acid (AA), acrylamide (AM), 2-acrylamide-2-methypropanesulfonic acid (AMPS), sodium acrylate (SA) and alkyl acrylate (RA) so as to obtain the R1, the R2, and the R3. The frostbite-preventing dust-suppressing agent can form a net-like structure with better water keeping property and stronger adhering property when being sprayed on the powder material under the condition of less consumption, thereby meeting the requirement of suppressing the dust and controlling the left spraying of the prior various powder materials when in transportation and storage to a wide range.
Description
Technical field
The present invention relates to a kind of powder material dust suppression agent and preparation method, particularly relate to a kind of dust-inhibitor and production method and using method of in powder body material transportation and stacking process, using.
Background technology
In industrial production; various powders are a kind of material forms that are most widely used; comprise coal, mineral dust, sandstone etc.; but in its transportation and original place when stacking; because the mobilization of air or the effect of jolting of transportation means, and cause dust from flying and Yan Lu to drop through regular meeting, this has not only caused serious environmental pollution; also can cause the serious waste of resource, even also can cause some production safety accidents.If therefore can develop a kind of dust-inhibitor, it is sprayed at powder body material surface, make powder body material form a kind of metastable surface texture, will address this problem to a great extent.
There are some dust-inhibitors to be developed now, but all can not satisfy actual needs, as the aqueous solution that has plenty of volatile-resistant substances such as spent glycol, propylene glycol constitutes, this system can suppress slight airborne dust to a certain extent, can be applied in the environmental sanitation field, but its solid dirt effect is quite faint; Have plenty of with utilizing the styrenic material, obtain latex shape material by letex polymerization, and play the effect of dust suppression, when this system is used for the dust suppression field, addition is bigger, also needs relatively large tensio-active agent, and if this class material can not complete reaction, its environmental toxicity is also bigger, so purposes is limited; It is main body that another system is to use water miscible polyvinyl alcohol, cooperate some tensio-active agents to constitute, this material toxicity is less, but when it uses, can become the polymeric membrane of hard within a short period of time, this is comparatively suitable for the less powder body material of particle, and for the bigger material of particle, its effect that prevents airborne dust is very limited.
Therefore, the invention provides a kind of system based on a kind of water miscible polyacrylate polymer material, it is under the situation of very little usage quantity, in the time of on being sprayed onto powder body material, can form a kind of reticulated structure, thereby can go up very on a large scale when satisfying existing powder body material transportation and stacking suppressing the needs that airborne dust and control are spilt with fine water retention property and very strong viscosifying power.
Summary of the invention
The purpose of this invention is to provide a kind of powder material dust suppression agent, this dust-inhibitor can form the quasi-network structure with certain cohesive strength after being sprayed at the powder body material top layer, and this protective layer does not influence the functions of use of powder body material, but has bonding, dust suppression effect.
