Preparation method of biomass water reducer

Abstract

The invention relates to a preparation method of a biomass water reducer and belongs to the technical field of preparation of cement additives. The preparation method comprises steps as follows: firstly, iron-rich animal giblets such as chicken liver and chicken blood are taken as raw materials, impure protein is removed by enzymolysis and heating, and biomass extract rich in heme iron is obtained; heme iron is reduced into ferrous ions by hydrochloric acid, and a protein reaction liquid rich in the ferrous ions is obtained; an etherifying agent is subjected to an etherification reaction withhydroxyl in the reaction liquid, a propyl sulfonic acid group is introduced into the reaction liquid, the etherified reaction liquid and septic matter of oil and fat are subjected to a reaction underthe action of potassium thiocyanate, and the biomass water reducer is prepared finally. The prepared biomass water reducer is low in mixing amount and good in water reducing effect and has broad application prospect.

Description

technical field [0001] The invention relates to a preparation method of a biomass water reducer, belonging to the technical field of cement additive preparation. Background technique [0002] Water reducing agent is a concrete admixture that can reduce the amount of mixing water under the condition that the slump of the concrete mixture is basically the same. As the most widely researched and used concrete admixture at present, water reducing agent can greatly improve the fluidity and slump of concrete, and at the same time, it can effectively reduce the mixing water consumption and significantly improve the working performance of concrete. Therefore, water reducing agents are widely used in the preparation of concrete required in the construction of houses, roads and bridges, airports, and dams. The concrete water reducers commonly used in my country are mainly lignosulfonate water reducers, naphthalene-based high-efficiency water-reducers and polycarboxylate-based high-pe...
