| titleOfInvention | A kind of preparation method of modified naphthalene series water-reducing agent suitable for mud-containing aggregates |
| abstract | The invention discloses a kind of preparation methods of the modified naphthalene series water-reducing agent suitable for mud-containing aggregates, belong to concrete admixture field, preparation method includes the following steps：Step 1: using unsaturated dicarboxylic acid (acid anhydrides), acrylamide, N vinyl pyrrolidones and silane coupling agent, multiple copolymer is made under the effect of persulfate sodium hydrogensulfite composite initiator；Step 2: using the homologue of naphthalene, multiple copolymer, the concentrated sulfuric acid and formaldehyde etc., modified naphthalene series water-reducing agent is made in sulfonated, hydrolysis, condensation and neutralization four-stage.The present invention introduces hydroxyl, amide groups, siloxanes etc. in the molecular structure of water-reducing agent, absorption of the clay layer structure to naphthalene water reducer can be reduced, avoid harmful effect of the aggregate clay content to naphthalene water reducer in concrete, solved under the premise of not improving naphthalene water reducer volume concrete diminishing not enough, low strength the problems such as. |
