Abstract

The invention discloses a kind of cement foamed agent prescription, it is related to building material field, it is raw material that the cement foamed agent prescription uses telomerization perfluoro octyl ethanol, normal butane, dimethyl pentane, dibenzoyl peroxide, diphenylphosphine, belong to physical blowing agent, especially creatively with the addition of dibenzoyl peroxide and diphenylphosphine, with surface-active higher, the surface tension of liquid can effectively be reduced, and arranged in liquid film surface electric double layer and surround air, bubble is formed, then foam is constituted by single isolated bubbles.The cement blowing agent has strong peptizaiton to cement granules, expands the contact area of cement and water, promotes hydration reaction, reduces water consumption, improves intensity, density and the impermeability of cement.

Description

Cement foamed agent prescription
Technical field
The present invention relates to building material field, a kind of cement foamed agent prescription is related in particular to.
Background technology
Foam cement is that foaming agent is mechanically fully foamed by the foamed system of foaming machine, and by foam and water Mud slurry uniform mixes, and then carries out cast-in-place construction or mould molding by the pumping system of foaming machine, is formed through natural curing A kind of novel light insulation material containing a large amount of sealed porositys.The raw material that existing cement blowing agent is used is more traditional, Cause foaming effect not good, causing the warmth retention property of foam cement can not further improve.
The content of the invention
Problem to be solved by this invention is to provide a kind of cement foamed agent prescription, with good foaming effect, improves The performance of foam cement sheet material.
To achieve these goals, the technical scheme taken of the present invention is：A kind of cement foamed agent prescription, its feature exists In the cement foamed agent prescription includes the component of following mass fraction：32~45 parts of telomerization perfluoro octyl ethanols, 26~33 parts just Butane, 12~19 parts of dimethyl pentanes, 14~22 parts of dibenzoyl peroxides, 5~8 parts of diphenylphosphines.
Beneficial effect：The cement foamed agent prescription uses telomerization perfluoro octyl ethanol, normal butane, dimethyl pentane, peroxide Change dibenzoyl, diphenylphosphine be raw material, belong to physical blowing agent, especially creatively with the addition of dibenzoyl peroxide and Diphenylphosphine, with surface-active higher, can effectively reduce the surface tension of liquid, and in the arrangement of liquid film surface electric double layer And air is surrounded, bubble is formed, then foam is constituted by single isolated bubbles.The cement blowing agent has strong dispersion to make to cement granules With, expand the contact area of cement and water, promote hydration reaction, water consumption is reduced, improve the intensity of cement, density and anti- Oozing property.
Specific embodiment
Embodiment 1：
The cement foamed agent prescription includes the component of following mass fraction：32 parts of telomerization perfluoro octyl ethanols, 33 parts of positive fourths Alkane, 12 parts of dimethyl pentanes, 14 parts of dibenzoyl peroxides, 8 parts of diphenylphosphines.
Embodiment 2：
The cement foamed agent prescription includes the component of following mass fraction：39 parts of telomerization perfluoro octyl ethanols, 28 parts of positive fourths Alkane, 15 parts of dimethyl pentanes, 17 parts of dibenzoyl peroxides, 6 parts of diphenylphosphines.
Embodiment 3：
The cement foamed agent prescription includes the component of following mass fraction：45 parts of telomerization perfluoro octyl ethanols, 26 parts of positive fourths Alkane, 19 parts of dimethyl pentanes, 22 parts of dibenzoyl peroxides, 5 parts of diphenylphosphines.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks Domain, is included within the scope of the present invention.
