Abstract
The invention discloses a quartz stone anti-fouling agent and a preparation method and application thereof. The quartz stone anti-fouling agent comprises the following raw materials in percentage by mass: 6-16% of methyl hydrosilicone oil, 2-8% of hydroxyl-terminated polydimethylsiloxane, 0-5% of methyl silicone oil, 1-2% of cosolvent, 0.5-5% of silane coupling agent and 70-85% of solvent. The quartz stone anti-fouling agent is specially developed for coarse and porous quartz stone which is vulnerable to fouling; and by simply smearing the anti-fouling agent on the surface of the quartz stone, the quartz stone can be effectively protected from oil pens, ink, coffee, tea and other pollutants. The quartz stone anti-fouling agent disclosed by the invention is simple in preparation process, good in anti-fouling property and favorable in scrub resistance and durability, can not influence the surface gloss of the quartz stone, and is non-toxic and non-corrosive, thus not only being applicable to the quartz stone, but also being applicable to agglomerated stone, marble, matt tiles and the like.
Description
Technical field
The invention belongs to quartz anti-soil technology field, it is related to a kind of quartz anti-fouling agent and its preparation method and application.
Background technology
Quartz be by more than 90% natural quartz (particle or micro mist etc.) and 10% about unsaturated-resin, colorant
With other additives composition.Be through negative-pressure vacuum, dither shaping, (temperature height is according to curing agent for heating cure
Depending on species) the sheet material that processes of production method.Its quality hard (Mohs' hardness 5-7), compact structure (density 2.5g/
cm3), there is the incomparable characteristic such as wear-resisting, pressure, high temperature resistant, anticorrosive, impermeable of other ornament materials.
But because there are some problems in manufacturing process, the resistance to soiling of quartz unlike a lot of producers declared so excellent
Different, such as test and be just easily penetrated into quartz using marking pen and ink and be difficult to clean up, so quartz is using
During easily occur oozing the problems such as dirt, variable color.For solving this problem, market occurs in that a variety of quartz anti-fouling agent products,
But their major parts are simply simply brought the anti-fouling agent of ceramic tile, marble etc. on quartz, so generally existing
Antifouling power is good and persistently or the problems such as can affect quartz surface gloss after using, and annoyings quartz industry always.
Content of the invention
Present invention aim to overcome that the antifouling power of existing quartz anti-fouling agent is good and not persistently or can affect after using
The technological deficiencies such as quartz surface gloss, provide quartz anti-fouling agent of a kind of excellent performance and its preparation method and application.
The preparation method of quartz anti-fouling agent of the present invention is: under stirring by 6～16% (quality) methyl
High containing hydrogen silicone oil, 2～8% (quality) hydroxyl-terminated injecting two methyl siloxane, 0～5% (quality) methyl-silicone oil add 70～85%
In (quality) solvent, then add 1～2% (quality) cosolvent, finally add 0.5～5% (quality) silane while stirring
Coupling agent, continues stirring 2 minutes, you can obtain quartz anti-fouling agent of the present invention.
Described methyl high containing hydrogen silicone oil hydrogen content is preferably 1.5%～1.6%.
The hydroxy radical content of described hydroxyl-terminated injecting two methyl siloxane is preferably 0.5%～10%.
Described methyl-silicone oil is preferably 100～1000mm in 25 DEG C of viscosity2·s-1.
Described cosolvent is preferably one or more of ethanol, ethylene glycol, glycerine or ethylene glycol ethyl ether.
Described solvent is preferably one of d40 solvent naphtha, gasoline, kerosene, diesel oil, petroleum ether, n-hexane, normal heptane
Or it is multiple.
Described silane coupler is preferably gamma-aminopropyl-triethoxy-silane (kh-550), γ-glycidyl ether oxygen third
Base trimethoxy silane (kh-560), γ-(methacryloxypropyl) propyl trimethoxy silicane (kh-570), n- β-(ammonia second
Base)-γ-aminopropyltriethoxy dimethoxysilane (dl602), n- (β mono- aminoethyl)-γ-aminopropyl front three (second) TMOS
One or more of (kh792).
Quartz anti-fouling agent of the present invention, under the driving of solvent, can be rapidly soaked into the minute aperture within quartz
In, solvent quickly volatilizees, and the active si-h key of the high containing hydrogen silicone oil of methyl, can be in the crosslinking of the active group of silane coupler
There is rapidly condensation reaction in the lower si-oh with hydroxyl-terminated injecting two methyl siloxane of effect；The reactive group of three passes through most preferably to join
Ratio synergy finally crystallisation solidification；Crystal closing blocking minute aperture, and formation has hydrophobic oleophobic on quartz surface
The transparent crystalline state protective layer of characteristic, crystal and protective layer are firmly anchored to quartz table by the grafting because of silane coupler
Layer, so scrubbing resistance and chemical stability is good, enables lasting anti-fouling effect.
Compared with prior art, the present invention has following outstanding advantages:
1. the quartz anti-fouling agent prepared by the present invention can protect multiple spots, by oil-dirts such as oil pen, machine oil
Be coated on the quartz surface processing through quartz anti-fouling agent of the present invention, more than 60 minutes after still can be wiped with napkin,
Leave no trace；Tea, ink, coffee etc. are coated on the quartz surface processing through quartz anti-fouling agent of the present invention,
Still can be washed away with clear water after more than 30 minutes, leave no trace.
2. the quartz anti-fouling agent prepared by the present invention has persistent feature, repeats to scrub more than 10 times still to multiple
Spot has protection effect.
3. the quartz anti-fouling agent prepared by the present invention is applied to quartz surface, only needs very small amount just permissible in remained on surface
Reach preferably antifouling power, without affecting the glossiness of quartz itself, on the contrary because of anti-fouling agent film layer crystallisation solidification, table can be made
Face glossiness increases 5-10 degree.
4. the quartz anti-fouling agent of the present invention is not only applicable to quartz, is also applied for marble, sub- light brick, hilllock stone etc..
5. the quartz anti-fouling agent of the present invention adopts environmentally friendly solvent, nontoxic non-corrosiveness.
The simple using method of anti-fouling agent is:
1. take the quartz sample block 120mm*80mm not doing antifouling process a piece of it is ensured that surface do clean；
2. take 2ml quartz anti-fouling agent, be stained with using paper handkerchief and be uniformly coated on sample block；
After 3.5-8 second, by sample block with new paper handkerchief wiped clean, imperceptible cover；
4. the sample block back side has identified time, sample batch and experimenter's name etc.；
5. after at least 12 hours, confirm sample block anti-fouling effect.
The simple test method of the quartz sample block that antifouling process is crossed is:
1. scribbled on the sample block doing antifouling process using black oily pen；
2., after half a minute, treat that person's handwriting parches；
3. gently wipe and oil pen's vestige can be wiped using dry paper handkerchief；
4. repeat above 1,2,3 steps 4 time, do not have any remaining trace to can be considered antifouling test passes, be for more than 8 times
Can be considered outstanding.
