Abstract

The invention specifically relates to an animal protein foaming agent with a high foam expansion ratio and a preparation method thereof, belonging to the field of foaming agents. The animal protein foaming agent is at least prepared from the following raw materials by weight: 2.5 to 25 parts of animal protein hydrolysate, 0.1 to 5 parts of a stabilizing agent, 0.1 to 5 parts of a dispersant, 1 to10 parts of a water reducer and 55 to 96.3 parts of water, wherein the stabilizing agent is any one or a mixture of more selected from a group consisting of cellulose derivatives and modified cellulose; the dispersant is an anionic surfactant; and the water reducer is any one or a mixture of more selected from a group consisting of polycarboxylate water reducers and naphthalene water reducers.

Description

technical field [0001] The invention relates to the field of foaming agents, in particular to an animal protein foaming agent. Background technique [0002] Foamed concrete is more and more widely used in the construction industry because of its excellent thermal insulation, sound insulation, fire resistance and frost resistance. At the same time, people have put forward higher and higher requirements for the performance of foamed concrete. The quality of foaming agent is an important factor affecting the performance of foam concrete. Compared with the first generation of rosin foaming agents and the second generation of synthetic foaming agents, protein foaming agents have attracted people's attention due to their wide range of sources, easy degradation, and no pollution to the environment, especially animal protein foaming agents. foaming agent. It has particularly good foam stabilizing properties and can be used to prepare low-density foam concrete. However, the animal...
