Modified hydrolyzed vegetable protein water reducing agent as well as preparation method and application thereof
The invention belongs to the field of gypsum building material water reducing agents, and discloses a modified plant hydrolyzed protein water reducing agent and a preparation method and application thereof.The water reducing agent comprises substances with the structure shown in the formula I. A = 20-25; b is equal to 15 to 20; x is equal to 30-40; y is equal to 40 to 45; z is equal to 5-10. The modified hydrolyzed vegetable protein water reducing agent is small in doping amount in a gypsum-based material, high in water reducing rate, small in gypsum strength loss, high in adaptability to the gypsum-based material and capable of reducing application of other retarding materials and reducing the cost of a gypsum-based additive, and has a certain retarding effect.
本发明属于石膏建筑材料减水剂领域，公开了一种改性植物水解蛋白减水剂及制备方法和应用，该减水剂包括具有式I所示结构的物质，其中，a＝20～25；b＝15～20；x＝30～40；y＝40～45；z＝5～10。本发明的改性植物水解蛋白减水剂在石膏基材料中掺量少、减水率高、对石膏强度损失小，并且具备一定的缓凝效果，对石膏基材料适应性强，可减少其它缓凝材料的应用，降低石膏基外加剂的成本。
