Description
Technical field
The invention belongs to the field of building materials, more particularly, to a kind of one-component paste gap filler and preparation method thereof.
Background technique
Along with the continuous development of glue for tile industry, more and more ceramic tiles have extended to metope from original ground paving
Paving, and ceramic tile can not close paving, need the influence in ceramic tile and ceramic tile there are certain gap to meet deformation to material,
It as buffering and must be decorated some specialized materials of full-filling between ceramic tile and ceramic tile simultaneously, tile grout then comes into being.
Gap filler on sale is broadly divided into following two categories on the market at present: the first kind is then to sell most commonly used water at present
Mud base gap filler, with cheap, easy for construction feature, but cement base gap filler needs scene that water or lotion is added
It is stirred, subsequent material construction can be carried out.Another kind of is then epoxies gap filler, and epoxies gap filler is expensive,
Long construction period, it is more demanding to construction personnel, while the curing method of epoxies gap filler is reacted jointly with curing agent, when
The two mix will appear when uneven do not solidify, the problems such as curing rate is too fast.
In the prior art, cement base gap filler and epoxies gap filler are mainly used.Cement base gap filler is in mix process
In to be easy to appear dispersion uneven, when powder is reunited with being constructed in rubber cement, the problems such as will appear cracking after dry, and
Its curing mechanism is mainly hydrated cementitious, and along with the progress of cement hydration process, material starts retrogradation, can not finally be constructed.
Epoxies pointing is expensive, although its construction effect is excellent, is not suitable for the outdoor joint filling for carrying out large area, epoxy exists
The problems such as ultraviolet light will appear xanthochromia, aging in the case where irradiating.Epoxy is solidified by two component reactions simultaneously, not right in ratio
When will appear that curing rate is slow, does not solidify or occur the phenomenon that implode.
Summary of the invention
The short construction period that can be encountered during actual construction it is an object of the invention to solve current gap filler, needs before construction
The problem of uniform mix, provides a kind of novel paste gap filler.
