Algae inhibition type solid water reducing agent and preparation method thereof
The invention relates to an algae-inhibiting solid water reducing agent and a preparation method thereof, and the algae-inhibiting solid water reducing agent is prepared from the following raw materials in parts by weight: 5-12 parts of small monomers with algae-killing and corrosion-preventing functions; 260 to 320 parts of a polyether macromonomer; 10 to 16 parts of an unsaturated ester small monomer; 32-40 parts of an unsaturated acid small monomer; 0.8 to 1.6 parts of a chain transfer agent; 2.4 to 3.0 parts of an initiator; and xylene. The prepared algal inhibition type solid water reducing agent has good algal inhibition performance, certain slump retaining performance and good water reducing performance, no preservative needs to be added, the polycarboxylic acid water reducing agent can be kept not to deteriorate for a long time, and the algal inhibition type solid water reducing agent can be independently used and can also be compounded with other water reducing agents for use.
本发明涉及一种抑藻型固体减水剂及其制备方法，一种抑藻型固体减水剂，以重量份数计，所述抑藻型固体减水剂的制备原料包括：灭藻防腐功能小单体5‑12份；聚醚大单体260‑320份；不饱和酯类小单体10‑16份；不饱和酸类小单体32‑40份；链转移剂0.8‑1.6份；引发剂2.4‑3.0份；及二甲苯。本发明制备的抑藻型固体减水剂具有良好的抑藻性能，且具有一定的保坍性能和良好的减水性能，无需另加防腐剂，可以保持聚羧酸减水剂长时间不变质，可以单独使用，也可以与其他减水剂复配使用。
