Block polyether, air entrained type polycarboxylate water reducing agent prepared by block polyether and preparation method thereof
The present invention provides a block polyether, an air entrained type polycarboxylate water reducing agent prepared by the block polyether and a preparation method thereof, the air entrained type polycarboxylate water reducing agent not only has excellent work performance, also has the function of improving the air content in concrete, can not only avoid the a series of compatibility problems caused by compounding with an initiator, also can replace a calcium lignosulphonate water reducer and can ensure the concrete strength and anti cracking performance. In addition, due to the polyether special block structure, the air entrained type polycarboxylate water reducing agent has surface activity different from that of unsaturated polyglycol ether, and can be soluble in an aqueous solution so as to avoid the occurrence of delamination and other situations.
