Environment-friendly mortar water reducing agent
The invention discloses an environment-friendly mortar water reducing agent which is mainly prepared from the following raw materials in parts by weight: 30-45 parts of a monomer component A, 40-60 parts of polyoxyethylene allyl ester, 15-20 parts of sodium lignin sulfate, 0.5-2 parts of a retarding component, 2-5 parts of a chain transfer agent, 0.5-1.2 parts of an initiator, 5-7 parts of solublealkali, 10-15 parts of a sulfonating agent and 30-40 parts of a solvent, wherein the monomer component A comprises maleic anhydride and styrene in a mass ratio of 1: 0.5-1: 1.2. The water reducing agent prepared from the raw materials improves the working performance of the water reducing agent in the application of high-strength concrete, the adopted raw materials are environmentally friendly and non-toxic, lignin sodium sulfate belongs to renewable energy sources, and the effects of being environmentally friendly and saving resources are achieved.
本发明公开了一种绿色环保的砂浆减水剂，主要由以下重量份的原料制成：单体A组分：30～45份；聚氧乙烯基烯丙酯：40～60份；木质素硫酸钠：15～20份；缓凝组分：0.5～2份；链转移剂：2～5份；引发剂：0.5～1.2份；可溶性碱：5～7份；磺化剂：10～15份；溶剂：30～40份；其中，所述单体A组分包括物质的量比例为1:0.5～1:1.2的马来酸酐和苯乙烯。该原料制备而得的减水剂改善了减水剂在高强度混凝土应用时的工作性能，且采用的原料环保、无毒，其中木质素硫酸钠属于可再生能源，具备了绿色环保，节约资源的效果。
