Abstract

The invention discloses a pea protein concrete foaming agent and a preparation method thereof. The preparation method is characterized by comprising the steps of: mixing 10 weight parts of pea protein, 0.1 to 1 weight part of papain and 200 weight parts of water, carrying out hydrolysis reaction for 0.5 to 24 hours under the temperature of 10 DEG C to 100 DEG C, deactivating enzyme, and filtering, wherein filtering liquid is a prepared mother solution of the pea protein concrete foaming agent; and uniformly mixing 30 to 200 weight parts of the mother solution of the pea protein concrete foaming agent, 1 to 10 weight parts of stabilizing agent, 1 to 10 weight parts of dispersing agent, 0.1 to 5 weight parts of preservative according to weight proportion to prepare the pea protein concrete foaming agent. The preparation method disclosed by the invention has advantages of readily available raw materials, low production cost, and favorable environmental friendliness, and is easy for realizing large-scale industrial production. A foaming process is simple, and the pea protein concrete foaming agent can efficiently enhance the foaming capacity, foaming stability and concrete consistencyand also efficiently enhance various performances of foaming concrete.

Description

technical field [0001] The invention belongs to a concrete foaming agent and a preparation method thereof, and relates to a pea protein concrete foaming agent and a preparation method thereof. It is suitable as a foaming agent for foamed concrete. Background technique [0002] Over the past 30 years of China's reform and opening up, efforts to create an "environmentally friendly and resource-saving" country have continued to increase, and energy-saving materials have become very popular. At present, the amount of wall materials in construction accounts for more than 70% of all building materials, and it is an important product that consumes raw materials and energy. With the implementation of my country's wall material reform and building energy-saving policies, the development and application of energy-saving building materials has received extensive attention, and new materials such as energy-saving, waste recycling, thermal insulation, light weight, and thermal insulatio...
