Description
Technical field
The present invention relates to gap filler field, further relate to a kind of double-component aqueous epoxy color sand gap filler and its application method and
Preparation method.
Background technique
In modern building ceramic tile have become main construction material be widely used for building interior and exterior wall and
The decorations on ground, for avoid ceramic tile and between due to expanding with heat and contract with cold generate hollowing, reserved one is needed between ceramic tile and ceramic tile
Fixed gap, the gap need tile grout to fill.Tile grout should have the coefficient of expansion and one close with ceramic tile
Fixed flexibility, can be with ceramic tile dilation together, to avoid crack is generated.The Main Components of tile grout are gelling material
Material, filler and additive, cementitious material assign gap filler bonding force, additive assign the good application property of gap filler, flexibility and
Other function, and filler has a great impact to the volume stability of gap filler and final dilation coefficient.Using same
The material of sample dilation coefficient can be further reduced a possibility that tile grout generates crack as filler.
Metope pointing currently on the market is mainly following two: (1) one is the ceramic tiles constructed mainly by trowelling
Color dinging agent: the construction of inorganic material, mainly trowelling, construction technology are more complicated.(2) another kind is the polymerization of squeezing and coating construction
Object colour joint trimming agent: it is made of high-tech new polymers and high-grade pigment, construction technology is simple, but expensive, seldom energy
It buys.Wherein, the adhesion strength of ceramic tile color dinging agent is high, not easily to fall off, mould proof, color is various, due to being inorganic material structure
At so material cost performance is high.Form of construction work is mainly trowelling, is cleaned out configured gap filler behind ceramic tile gap along porcelain
The diagonal of brick is uniformly expressed in reserving gaps, carefully scrapes off extra slurry, is used after slurry primary solidification
Jointing agent extra on ceramic tile is further pressed joint filling by micro- wet sponge, so that joint filling is closely knit, surface is smooth.After jointing agent is dry again
Thorough cleaning is carried out with micro- wet sponge.
Currently, resin base gap filler is using epoxy resin as base-material, addition silica flour, titanium dioxide, acrylate functional compound,
Acrylate radical siloxane, hollow glass micropearl, glass fibre and stearic acid, have that elasticity is good, quick solidifying, cohesive force are strong, strong
The features such as spending high, good water-proof effect and being free of hazardous solvent.But the resin base gap filler is mainly for the gap of indoor ceramic tile
Design, it is poor to the adhesion strength of old concrete, and after long-time use, the intensely dark pool that color can become, to lose
Decorative effect.

(2) solid is placed in 10 parts of hydrochloric acid, pH 4, after stirring 0.5 hour, takes out solid, drying can be prepared and change
Fumed silica after property.
It is found by the applicant that the intensity of the gap filler after heretofore described double-component aqueous epoxy color sand underfill cures increases
By force, secondly color is more bright-coloured and non-reflective, it may be possible to, can be with since fumed silica has the function of reflection light
As ultraviolet absorber, but just because of its reflection function with light, so that after the underfill cures after pigment are added
Color and color before curing it is inconsistent, cause that trace significantly sews and mend.In addition, applicant has been surprisingly found that, using multi-arm type
Curing agent preparation underfill cures after the intensity of gap filler be further enhanced；It may be multi-arm type that applicant, which speculates,
Curing agent its curing rate be equivalent to for curing agent, curing rate can be slightly fast, but consolidating of being weaker than of its intensity
Agent.In the present invention, the modification fumed silica of addition, is core-shell structure, not only be can solve because of silica
Reflection light reason causes the variation of color, while due also to the hydroxyl and polar group and epoxy on surface play bonding action,
So as to reinforce the intensity of the gap filler after solidifying.
In some embodiments, the pigment be selected from bronze, porcelain is white, ivory is golden, moonlight is silver-colored, champagne, light gold, gold-plating
One of golden, diamond gold, glittering gold, silver grey, coffee color, Peal blackberry or a variety of combinations.
