Cement foaming agent

Abstract

The invention discloses a cement foaming agent which comprises the following raw materials in parts by weight: 1-1.9 parts of rosin, 0.5-1 part of bone glue, 0.2-0.5 part of sodium hydroxide, 0.2-0.5 part of lauryl sodium sulfate, 3-5 parts of glutinous rice starch and 90-95 parts of water. The rosin is first level rosin, the bone glue is high quality bone glue, and the cement foaming agent also comprises 0.5-1 part of a silicone resin polyether emulsion as a foam stabilizer. The cement foaming agent is high in foaming rate, good in cement compatibility and stable in foam, is light in weight, high in strength, small in dosage and low in cost, is good in fireproof and waterproof properties, free of radioactivity and wide in application, and has energy-saving and environmental-friendly effects; the raw materials are easily available, and the preparation process is simple and easy to implement.

Description

technical field

[0001] The invention belongs to the technical field of foaming agents, in particular to cement foaming agents. Background technique

[0002] At present, when fly ash and cement are used as the main raw materials to produce frame structure non-load-bearing lightweight partition wall panels and blocks, foaming agents must be used for foaming. There are many types of foaming agents, currently mainly include: rosin soap foaming agent, metal aluminum powder foaming agent, vegetable protein foaming agent, animal protein foaming agent, resin soap foaming agent, hydrolyzed blood glue foaming agent, Aluminum sulfonate foaming agent, etc. All kinds of foaming agents have their own advantages and disadvantages. Rosin soap foaming agent is a kind of foaming agent used earlier. It is a kind of surfactant prepared by saponification reaction with rosin and sodium hydroxide as the main raw materials. Its main component is sodium salt of rosin resin. Appearance is light ye...
