Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of mortar joint and preparation method thereof
Background technology
Mortar is a kind of commonly conventional construction material, is essential auxiliary products in construction.Board wall with by
Contact site is of different sizes because the reason such as artificial and natural is commonly present between concrete, other different components of cement mortar composition
Gap, not only affect the performance of building, and influence specious, and conventional inorganic seam material on the market at present
There is easy to crack, the shortcomings of being bonded insecure in material, and organic joint filler has the shortcomings of pollution environment, easy aging.Therefore, need
Study new mortar joint, make it have have good workability, not easy to crack, adhesive strength it is high, the characteristic such as nontoxic.
The content of the invention
The purpose of the present invention is to be to provide a kind of mortar joint and preparation method thereof, mortar joint adhesion strength height,
Not easy to crack, texture is soft and smooth.
First, the present invention provides a kind of mortar joint, and its raw material components and each component account for the mass percent of raw material total amount
Respectively：
Preferably, the binder materials is the mixture of cement, gypsum or cement and admixture；Cement is PO42.5R water
Mud or the 52.5R cement of P II, gypsum are α~gypsum or dihydrate gypsum, and admixture is flyash or levigate stone flour.
Preferably, fine aggregate is dries river sand after washing, and its particle size range is 0.38~2.36mm.
Preferably, cellulose ether is hydroxypropyl methyl cellulose ether or ethoxyl methyl cellulose ether.
Preferably, redispersable latex powder is vinylacetate and ethylene copolymer latex powder or ethene and vinyl chloride and the moon
Laurate fat ternary polymerization latex powder.
Preferably, the accelerator is calcium formate or sodium metasilicate.
Preferably, 0~50 μm of the diameter of the PP fibers, 0~10mm of length.
Secondly, present invention also offers the preparation method of above-mentioned mortar joint, comprise the following steps：
The mass percent of raw material total amount is accounted for by feed components, binder materials, fine aggregate, cellulose are accurately weighed respectively
Ether, redispersable latex powder, accelerator and PP fibers, are poured into after mortar mixer stirs, and the allotment that adds water is to suitable consistency
The mortar joint can be obtained.
Matched using the mortar joint of the present invention, after each component is mixed evenly in mortar mixer in proportion,
Packaging, adds water to suitable consistency and can be used when using.Mortar joint of the present invention has adhesion strength high, not easy to crack, texture
Soft and smooth the features such as.
