Mosaic provided by the invention becomes connection tackiness agent and manufacture craft thereof to have following characteristics:
(1) tackiness agent of the present invention can use separately, makes mosaic Cheng Lian, does not need the base materials such as papery, silk screen.
(2) tackiness agent of the present invention has splendid water tolerance, water tolerance be front two generation mosaic become 60 to 120 times of coupling white glue with vinyl, can keep good cohesive force in 10 hours in the boiling water.This tackiness agent has good weathering resistance, solvent resistance, resistance to acids and bases simultaneously.To the mosaic storage condition require far below front two generation mosaic become the coupling white glue with vinyl, and guarantee that the mosaic particle does not come off.
By the bonding mosaic back side very small area and very little facade area, the assurance mosaic back side has 92% adhesive-free area when (3) becoming the connection mosaic owing to this tackiness agent of use.Therefore the front need not paper substrates, can not occur not removing front base material operation when paper substrates makes moist the phenomenon of shrinking and construction, has improved operating efficiency and quality, the shortcoming that also can not exist the mosaic particle to extract.Guarantee the mosaic particle back side 92% glue-free area when this tackiness agent is bonding simultaneously, therefore also do not exist s-generation net subsides mosaic fibrous reticulum and white glue with vinyl area to surpass 60%.Have a strong impact on the wetting contact of mosaic particle and cement or glue for tile, thus the bonding strength when impact is constructed.The phenomenon that causes mosaic to come off from metope or buildings easily.
(4) shape that this tackiness agent can the arbitrary combination mosaic, and the mixed bonding Cheng Lian that takes of unlike material mosaic.Simultaneously bonding strength be higher than front two generation the mosaic tackiness agent
(5) the mosaic particle gap of this tackiness agent Cheng Lianhou can not change, and guarantees the aesthetics of mosaic.This be since tackiness agent of the present invention have fabulous water-fast, weather-proof, high strength, high tenacity, outstanding mosaic constancy.
(6) use of this tackiness agent can improve mosaic manufacturer efficient, and efficient doubles.Because this tackiness agent can be put gum forming or screen printing moulding by point gum machine, therefore improved the technique that domestic paper pasted and netted the manual pasting that pastes, production efficiency doubles.
Embodiment
The below will describe the present invention in detail by specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Mosaic provided by the invention becomes the connection adhesive components as follows:

2, pvc resin paste grade: K value scope at 60~90 homopolymerization pvc resin paste grade, K value scope at 60~90 copolymerization pvc resin paste grade, one or both in the blending pvc resin paste grade.Optimum is one or both in homopolymerization pvc resin paste grade (K value scope is at 65-70), the copolymerization pvc resin paste grade (K value scope is at 65-80), content range 18%-33%, optimized scope 22%-30%.The adhesive solidification film forming was not fine and close when content was lower than 18%, caused water tolerance to descend, and this moment, the intensity of glue was also lower, was not suitable for mosaic Cheng Lian.When content greater than 33% the time, can cause the adhesive solidification film forming after toughness descend, also be not suitable for and mosaic Cheng Lian.
3, solidifying agent: a kind of in the TDI-TMP affixture that the reaction of tolylene diisocyanate and TriMethylolPropane(TMP) makes, hexamethylene diisocyanate (HDI) biuret, hexamethylene diisocyanate (HDI) tripolymer, toluene diisocyanate trimer, isophorone diisocyanate trimer, castor oil polyhydric alcohol diisocyanate prepolymer, Abietyl modified Viscotrol C glyceryl alcohol type (TDI) prepolymer, the Versamid.Content range 0.5%-2%, optimum content range 1.2%-1.8%, content is lower than 0.5% and causes the curing of blocked polyurethane performed polymer component incomplete, be unfavorable for that mosaic becomes connection bonding, when the content that surpasses 2%, it is too fast to cause blocked polyurethane performed polymer component to be solidified, and is unfavorable for the toughness of tackiness agent, causes toughness to descend.
4, blocked polyurethane performed polymer: 3, a kind of in hexamethylene diisocyanate (HDI) the tripolymer performed polymer of hexamethylene diisocyanate (HDI) the tripolymer performed polymer of hexamethylene diisocyanate (HDI) performed polymer of 5-dimethyl pyrazole end-blocking, 3,5-dimethylpyrazole end-blocking, hexamethylene diisocyanate (HDI) performed polymer of methyl ethyl ketoxime end-blocking, methyl ethyl ketoxime end-blocking, the tolylene diisocyanate performed polymer of methyl ethyl ketoxime end-blocking.Content range 1.0%-12%, optimized scope 5%-9%.This component plays bonding effect, and when content was lower than 1.0%, bonding force was not good, and when content was higher than 12%, the manufacturing cost of tackiness agent was too high.
5, nano-calcium carbonate: content range 6%-13%, optimized scope 10%-12%.
6, water-ground limestone: content range 3%-16%, optimized scope 5%-8%.
7, calcite in powder: content range 3%-23%, optimized scope 11%-18%.
5,6,7 three components play modifying function, and consumption too much affects intensity and the toughness of tackiness agent, the very few rising that also can cause manufacturing cost of consumption simultaneously.
8, coupling agent: γ-aminopropyl triethoxysilane, γ-(2, the 3-glycidoxy) a kind of in propyl trimethoxy silicane, γ-mercaptopropyl trimethoxysilane, two-(γ-triethoxyl silane propyl group) tetrasulfide, γ-diethylenetriamine base propyl-triethoxysilicane, anilinomethyl trimethoxy silane, β-(3,4-epoxycyclohexyl) ethyl trimethoxy silane.Content range 0.1%-1%, optimized scope 0.3%-0.6%.Water tolerance when content is lower than 0.1% behind the adhesive solidification is bad, can affect the compactness of glued membrane when being higher than 1% during baking-curing, and is same influential to the water tolerance of glue.
9, thermo-stabilizer: one or both in zinc oxide, stearate acid calcium, Zinic stearas, dibutyl tin laurate, dibutyl tin laurate mixture, Bis(lauroyloxy)dioctyltin, maleic acid ester butyl tin, maleic acid ester tin octylate, mercaptan butyl mixture, mercapto machine 2-ethyl hexyl ethanoate one/dibutyl tin, dibutyltin oxide (Dibutyltin oxide), the monobutyltin oxide.Content comprises 0.3%-4.5%, optimized scope 0.6%-3.2%.Content toasts heat-resisting capacity of decomposition and descends when being lower than 0.3% glue film forming, excessive little to the heat decomposition resistance lifting when being higher than 4.5% content, causes the waste of thermo-stabilizer.
10, water-removal agent: in monocycle oxazolidine, bicyclo oxazolidine, calcium oxide, the p-methylphenyl sulfonyl isocyanate one or both.Content range 0.2%-6%, optimized scope 1.6%-4%.Water removal effect was bad when water-removal agent was lower than 0.2%, also had moisture entrapment, affected curing and the storage of glue.Greater than 6% the time, when storing, cause again the very easily moisture in the absorbing air of glue, affect equally curing and the storage of glue.
11, thixotropic agent: a kind of in wilkinite, organobentonite, white rouge aerogel, the aerosil.Content range 0.4%-1.8%, optimized scope 0.8%-1.4%.The thixotroping ability of glue was bad when thixotropic agent was lower than 0.4%, trickled easily during baking, and glue is from the trickling of particle gap to positive when causing mosaic to become connection, and it is attractive in appearance to affect the Marseille.Addition tackiness agent viscosity greater than 1.8% time is too high, is unfavorable for a glue or brush application.
12, thinner: a kind of in diethylene glycol dimethyl ether, methyl aceto acetate, solvent kerosene, the glycol dimethyl ether.Content range 0%-2%.
In the said components:
1,2 components mainly play filming function, can make this tackiness agent reach the effect of independent connection mosaic.
