Description
Technical field
The invention discloses a kind of crack resistence cement base tile grouts, belong to building material technical field.
Background technology
Ceramic tile is widely used in building field because it has many advantages, such as beautiful and generous, hard solid.Tile grout conduct
The mating pointing of tile paste increases along with ceramic tile usable floor area and is increased.As people's living standard and understanding improve,
Tile grout also develops to the polymer-modified cement-based gap filler of current mainstream from initial white cement.
Gap filler is more a kind of chemicals in building trade, and gap filler is mainly used for facing tile facing body
System, quality directly affect outer wall decorative effect.Usually it is strong with adhesion, contraction is small, color pull-out capacity is strong, has anticracking
The flexibility of line, decoration texture is good, and compressive resistance is wear-resistant, antimycotic feature.
Currently, the gap filler used in tile decorative surface is wrapped through mixing using ordinary cement, building fine sand, inorganic pigment mostly
Dress, temper the packing material stitched as ceramic tile when using, using the time that do not grown after the completion of the construction of this tile grout
It through wind, solarization, drenches with rain, under the influence of the factor of natural environment of freeze thawing etc., the ceramic tile metope whiting that large area will occur is returned
Alkali, contraction fissure, go mouldy, even ceramic tile falls off and other issues and security risk.This field once occurred using epoxy resin,
Curing agent and the technical solution of filler mixing filling attempt thoroughly to solve problem above.But epoxy resin used in such scheme and
Curing agent is all no-solvent type, is easy to pollution ceramic tile surface in use, and cleaning is extremely difficult, is easy to leave a trace,
Meanwhile construction appliance also extremely difficult cleaning, cause construction inconvenient.There is also cracking resistances for tile grout traditional at present not
Good problem, therefore also need to study it.
