| titleOfInvention | A kind of preparation method of dust suppressant |
| abstract | The invention belongs to miberal powder dust suppressant technical field, it is therefore an objective to provide that a kind of concentration is low, price is relatively relatively inexpensive, will not cause the preparation method of the miberal powder dust suppressant of secondary pollution, this method comprises the following steps：Take the stalk of 100 parts of parts by weight, stalk is crushed, then add a certain proportion of bleaching agent and carry out bleaching, the rosin of 5 10 parts of parts by weight is added in stalk after bleaching, it is to be mixed uniformly after, appropriate sodium hydroxide solution is added again, it is heated to 80-100 DEG C, and pH value is adjusted between 59, a kind of progress etherification process added afterwards in monoxone or the hydroxypropyl-trimethyl ammonium chloride of 3 chlorine of cationic etherifying agent 2, the dosage of monoxone or the hydroxypropyl-trimethyl ammonium chloride of 3 chlorine of cationic etherifying agent 2 is 40%-the 60% of stalk and rosin gross weight, after reaction 80 minutes, it is vacuum dried again, produce dust suppressant.The present invention not only solves the environmental issue of stalk, and also solves the dust pollution question in mineral windrow and transportation. |
