Description
Technical field
The invention belongs to cement technology fields, and in particular to the super flexible self-leveling cement of bicomponent cement base.
Background technique
Self-leveling cement is a kind of high-new environment-friendly products high in technological content, sport technique segment is more complicated.It is by a variety of
The dry-mixed type pulverulent material of active constituent composition, scene are mixed water and be can be used.Slightly it is unfolded through scraper, can be obtained high smooth base
Face.Self-leveling cement setting rate is fast, and people's walking can be gone up after 4-5 hours, and surface construction can be carried out after 24 hours (such as paving wood
Plate, adamantine plate etc.), quick construction, simplicity are traditional artificial levelling incomparable.Its is safe and pollution-free, beautiful, fast
The characteristics of speed construction is with coming into operation, being self-leveling cement.But the generally existing cement-based self-leveling cement master of existing market
It to be mixed with ordinary portland cement, aluminate cement, gypsum, washing baked sand etc. for primary raw material.Self-leveling cement
Itself have many advantages, such as that speed of application is fast, simple process, short construction period, but at present self-leveling cement have be easy to crack,
The risk of hollowing.The cracking and hollowing of self-leveling cement are related with the volume stability that each producer is formulated, but existing with building site
Ground base, whether there are also with temperature extraneous when construction, humidity, ventilation, whether direct sunlight has very big pass
System.And cement inherently has shrinkage.
Summary of the invention
In order to solve the above technical problems, the present invention will dry a part washing inside common self-leveling cement raw material
Sand is replaced with rubber grain, and common self-leveling cement construction site directly adds water and stirs, and the present invention is to stir common plus water
Mix be changed to solid content be 25 percent acrylic acid and self-leveling cement be added together stirring.Because of normal silicate water
Mud itself has shrinkage, and aluminate cement and gypsum have dilatancy, so the convergent-divergent of self-leveling cement itself is no
It is too stable, and rubber grain itself has certain elasticity, can effectively alleviates the convergent-divergent of self-leveling cement, third
Olefin(e) acid lotion also has certain elasticity after parching, and has both certain adhesive force, so the present invention can be to greatest extent
Reduce self-leveling cement hollowing cracking risk.
To achieve the above object, the technical solution adopted by the present invention is that: the super flexible self-leveling cement of bicomponent cement base,
It include rubber grain in the self-leveling cement.
Preferably, self-leveling cement specifically includes following raw material by weight percentage:
Preferably, the washing baked sand is 70~110 mesh.
Preferably, the rubber grain is 40~70 mesh.
Preferably, it is solid that 6.5L is added when using in every 25 kilograms of super flexible self-leveling cements of bicomponent cement base
The acrylic emulsion that content is 25% is as stirring liquid.
The beneficial effects of the present invention are: a part inside common self-leveling cement raw material is washed baked sand by the present invention
It is replaced with rubber grain, common self-leveling cement construction site directly adds water and stirs, and the present invention is to add water and stir common
It is changed to the acrylic acid that solid content is 25 percent and is added together stirring with self-leveling cement.With it is existing currently on the market
Self-leveling cement is compared, and present invention flexibility with super strength and adhesive force can effectively control the sky of self-leveling cement
Drum cracking, and floating is not grey on surface of the present invention, and floor glue and self-leveling cement binding force can be allowed to increase, and prevents because floating
The bulge phenomenon of PVC floor caused by ash processing is not clean.
