| titleOfInvention | A kind of coal dust depressor and preparation method thereof |
| abstract | The invention discloses a kind of coal dust depressor, it is made up of the raw material of following weight portion: modified sunflower straw 1 part, degree of neutralization be 50%～70% acrylic acid solution 14～32 parts, ethylene glycol dimethacrylate 0.0048～0.0176 part, purified silicious earth 0.2～0.8 part, initiator 0.02～0.04 part；It addition, the invention also discloses the preparation method of a kind of coal dust depressor.The present invention uses the purified silicious earth containing abundant internal microcellular structure as nucleator, water soluble molecules acrylic acid is as polymerization monomer, traditional method is replaced to prepare the starch used in dust suppressant with the modified sunflower straw that content of cellulose is high, decomposition of initiator is promoted by microwave radiation, the core surface making acrylic acid and cellulose be formed at diatomite particle carries out situ-formed graft copolymerization, form the copolymer of shell core package structure, prepare and there is excellent water suction, water retention property and the coal dust depressor of good filming performance. |
