| titleOfInvention | A kind of preparation method of polymer for drilling fluid shale control agent |
| abstract | The invention discloses a kind of preparation methods of polymer for drilling fluid shale control agent, with acrylamide, acrylic acid, potassium hydroxide, dimethyl diallyl ammonium chloride is raw material, polymer shale control agent is prepared by inverse emulsion polymerization method, it synthesizes optimum condition are as follows: acrylamide, acrylic acid, three kinds of monomer weight parts of dimethyl diallyl ammonium chloride are respectively 70 ~ 80 parts, 70 ~ 80 parts, 15 ~ 75 parts, three kinds of monomers are configured to the water phase that pH value is 10, 10 parts by weight Emulsifier Sp-80 are added, T-60, make its emulsion dispersion in the white oil of 100 parts by weight, stabilizer N is added, N ’ Bimonthly 1 ~ 3 part of osmanthus Ethylene Diamine diethyl sodium sulfonate, reaction temperature is 30 ~ 40 DEG C, reaction time 8h, oxidation/reduction ratio of initiator n Potassium peroxydisulfate : n Sodium hydrogensulfite =1:1, initiator are 0.4 parts by weight.The product can be adsorbed on surface of clay and form a kind of semi-permeable membrane, and have stronger encapsulation action, can effectively wrap up landwaste and weaken it by aquation dispersion effect, while compression double electric layer avoids hydration and expansion of clay, inhibitory effect is prominent. |
