Abstract
The present invention relates to technical field of building construction, specifically disclose a kind of cement foamed agent prescription of combined wall, it is made from the following raw materials in parts by weight: 8-15 parts of lauryl sodium sulfate, 2-3 parts of normal butane, 1-2 parts of dimethyl pentane, 2-3 parts of surfactant, 1-2 parts of foam stabilizer, 10-15 parts of organic solvent, 0.2-1 parts of chelating agent, 1-2 parts of thickener, the present invention overcomes the deficiencies in the prior art, utilize lauryl sodium sulfate, normal butane, dimethyl pentane, surfactant, foam stabilizer, organic solvent, chelating agent, thickener is made, this foaming agent belongs to physical blowing agent, by adding dibenzoyl peroxide diphenylphosphine, surface-active with higher, surface tension of liquid can be effectively reduced, and it arranges in liquid film surface electric double layer and surrounds air, form bubble, Foam is formed by single isolated bubbles again, uses silicone amide as foam stabilizer, significantly improves air hole structure, string hole is reduced, improves intensity early period of cement, wettability is strong, dosage is few, and overall cost is low.
Description
Technical field
The present invention relates to technical field of building construction, particularly belong to a kind of cement foamed agent prescription of combined wall.
Background technique
Reform currently, country largely advocates building energy conservations and wall energy conservation, in recent years foamed cement or foam concrete because
Its environmental protection, energy conservation, the advantages that thermal and insulating performance is good and by high praise, traditional cement blowing agent includes rosin and protein
Class two major classes.The chemical structure of rosin foaming agent is more complicated, belongs to anionic surfactant, can be with the calcium ion in cement
Reaction generates insoluble salt, needs to heat melting when in use, and its coefficient of foaming is low and foam stability is poor.Moreover, loose
The production of fragrant pyrolytic polymer is using virose phenol as raw material, and performance is about the same compared with rosin soap, but its production cost and
Price is all higher, and there are security risks and environmental problem.Protein-based foaming agent is divided into animal protein foaming and plant egg
White hair steeps two classes, and animal protein foaming agent is at high cost and has penetrating odor, what plant proteins foaming agent used when preparing
Various natural polymer raw material quality stability not can guarantee, and cause the foaming performance stable of vegetable protein foaming agent product
It is poor, cannot achieve large scale application, and protein-based foaming agent vulnerable to external environment influences such as temperature and acidity and
Denaturation, there is very big limitation in production application.Existing cement foamed raw material is more traditional, and foaming effect is bad,
The present invention is to solve the problems, such as that traditional cement blowing agent performance is poor and unstable.
Summary of the invention
The object of the present invention is to provide a kind of cement foamed agent prescriptions of combined wall, to solve traditional cement blowing agent
Performance difference and unstable problem.
To solve the above problems, the technical solution used in the present invention is as follows:
A kind of cement foamed agent prescription of combined wall, is made from the following raw materials in parts by weight: 8-15 parts of lauryl sodium sulfate, just
2-3 parts of butane, 1-2 parts of dimethyl pentane, 2-3 parts of surfactant, 1-2 parts of foam stabilizer, 10-15 parts of organic solvent, chelating agent
0.2-1 parts, 1-2 parts of thickener.
Further, it is made from the following raw materials in parts by weight: 9 parts of lauryl sodium sulfate, 2.2 parts of normal butane, dimethyl-penten
1.3 parts of alkane, 2.2 parts of surfactant, 1.2 parts of foam stabilizer, 12 parts of organic solvent, 0.3 part of chelating agent, 1.2 parts of thickener,
Further, the surfactant is dibenzoyl peroxide and diphenylphosphine mixture, and matching is 3:1.
Further, the chelating agent is sodium citrate, and the foam stabilizer is silicone amide, and the organic solvent is second two
Alcohol butyl ether, the thickener are polyacrylamide.
Compared with prior art, implementation result of the invention is as follows by the present invention:
The cement foamed agent prescription of a kind of combined wall of the present invention, utilizes lauryl sodium sulfate, normal butane, dimethyl-penten
Alkane, surfactant, foam stabilizer, organic solvent, chelating agent, thickener are made, this foaming agent belongs to physical blowing agent, by adding
Add dibenzoyl peroxide diphenylphosphine, surface tension of liquid can be effectively reduced in surface-active with higher, and in liquid film table
Face electric double layer arranges and surrounds air, forms bubble, then form foam by single isolated bubbles, foam has good elasticity, makes
It uses silicone amide as foam stabilizer, significantly improves air hole structure, reduce string hole, improve intensity early period of cement, pollution-free, use
Convenient (not having to impregnate), wettability is strong, dosage is few, and overall cost is low, and the present invention improves the intensity of cement, density and antiseepage
Property, social benefit is obviously suitble to promote.
