Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of speed for ornament materials bonding
Solidifying type ornamental stone early strong rubber stick, rapid-hardening ornamental stone early strong rubber stick is for bonding applique surface material
Bonding with by viscous matrix, bonding applique surface material have lithotome, natural boards, artificial stone,
The decorative material material such as artificial board, environment stone material, ceramic product, tapestry brick, mosaic, are subject to
Viscous matrix has building concrete body of wall, mattess, mortar wall surface, mortar ground, various
Natural crystal material, lithotome, artificial decoration materials etc..
Background technology
Adhesive is the one for ornament materials with cement products basal plane, ornament materials and stone material
Alite paste, is mainly made up of cement and fine sand.On the one hand, the existing cement-based adhesive of China is general
Flow-through, there are the defects such as tensile bond strength (24h) in early days is low, construction is slow, weather resisteant difference；On the other hand,
When having the adhesive of preferably in early days tensile bond strength (24h), have that setting time is short, operable time
The deficiencies such as short, weatherability is poor.Therefore, along with the continuous lifting of architectural aesthetic sense, substantial amounts of decoration materials face
Generation, it is common that maximization, the heavy ornament materials of resistance to impact, will make this decoration materials etc. be able to large area and make
With, it is necessary to have one have operable time length, Early-age behavior good, can rapid construction, high temperature resistant,
Freeze thawing resistance, the special adhesive of resistance to immersion.In a word, domestic existing cement-based adhesive exists
The problems such as performance is slow, can not paste heavy large-scale decoration materials, weatherability is poor.

Inventive principle:
Above-mentioned rapid-hardening ornamental stone early strong rubber stick is to be formed by the two big uniform mixs of component: component one, nothing
The cement original washing powder material of machine mineral/chemical compound homogenizing；Component two, has the thin collection of particle diameter linear distribution feature
Material.Present invention utilizes following technology:
1. micro-nano SiO2Powder interface is filled and modification technology.First, active nano SiO2Subparticle
Particle size interval is 5nm～10 μm, can be filled into the hydrated mineral vestibule after cement powder aquation, free water is waved
In the spaces such as the capillary left over after Faing, reduce and reduce the micropore in adhesive hardened paste, improve mortar
Packing；Second, active nano SiO2The Ca (OH) generated with cement early hydration2Slurry penetrates into base together
In the interface cavity of body and microcosmic vestibule, reaction generates calcium silicate crystals, it is achieved that the infiltration between interface is bonding
With promotion aquation；3rd, active nano SiO2Meet after water with latex powder and be interweaved, thus realize rubber powder with
The interfacial reaction type interactivity of cement is bonding, modified hydrated calcium silicate and the high intensity at bonding matrix interface
Bonding and improve weatherability.
2. sustained release agent-hydrophober-cellulose ether hydridization delay technique.By slow release and the hydrophobic of sustained release agent
The hydrophobicity of agent, when, after adhesive mix aquation, the dust diluent in sustained release agent acts on jointly with hydrophober
Free water, forms the vapor-permeable type thin barrier film of free water, is collectively forming the water retention mingled with cellulose ether,
Reduce the volatilization loss of free water.By the method closed by free water, increase the hydration time of complex cement,
And then realize the prolongation of rapid-hardening cement material operable time.
The most non-same series cement is compounding designs fast hard technology.On the one hand, utilize hydridization delay technique delays sulphur
The hydration rate of aluminate cement so that it is reach unanimity with the presetting period of portland cement；On the other hand,
Participate in absorbing the calcium hydroxide that silicate cement hydration produces by flyash and silica flour, accelerate silicate water
The curing rate of mud, it is achieved adhesive strength in early days.
Invention advantage:
Owing to technique scheme is used, the present invention compared with prior art has the advantage that

Write the adhesive property improving cement base stone adhesive, make the fast rigid ornamental stone glue of rapid-hardening
Stick achieves rapid construction, the effect of the strongest bonding；
2) slow setting after there is mix, start the feature that solidifies rapidly when condensing, can preferably use
In engineer applied, it is simple to operation, when proportioning devises the operation of stone adhesive specially
Between rather than rely on traditional cement initial set, final set self-characteristic；
3) this cement base stone adhesive can normal construction application in the winter time；
4) this cement base stone adhesive has excellent immersion tensile bond strength and freeze thawing follows
Ring after-drawing adhesion strength, hangs 10min after-drawing adhesion strength and does not loses.
