Background technology
High-performance clean-cloth should be able to effectively remove dust, greasy dirt and watermark without damaging by the surface of cleaning piece.Dust
It is the primary goal of cleaning, and instrument and meter, machine lathe surface, family kitchen etc. be unavoidably with the presence of greasy dirt, because
This needs the clean-cloth to have good degreasing result.Common clean-cloth has good fluid absorbent, and related
Scholar's research obtains the water imbibition of Superfine Fibre Fabric far above oil absorption, it is possible that hydrone is occupied greatly during treatment greasy dirt
Segment space, and a small amount of fluid is remained in by the phenomenon on cleaning piece surface.If clean-cloth can adsorb oil, then treatment
Remaining raffinate will become more succinct.
At present, carry out oil spilling treatment using oil absorption material and be presently the most conventional method.Oil absorption material can effectively be located
Reason marine oil spill, the features such as easily recovery with efficient, economy, oil product.Conventional oil suction material is largely divided into three major types, i.e., inorganic
Oil suction material, organic synthesis oil suction material and organic natural oil suction material.Common used material;Organic natural oil suction material includes wheat
Bar, corn ear, wood fibre, cotton are fine, mestha, bark and peat bog etc., and the oil absorbency of wherein most is all than organic synthesis tree
The oil absorbency of fat is high.
Non-woven material has larger hole is left between special three-dimensional structure, fiber, therefore such Wiping material
Structure is more loose, and the scope of thickness is big, adapts to different purposes.The non-weaving cloth reinforced by chemical adhesion, surface cure
Adhesive may make to be wiped article surface and damage, problem of environmental pollution can be also brought in process.Cotton Wiping material is more
It is hydrophilic oleophobic property, the clearance to greasy dirt is poor, receives that oily power is low, dirt-removing power is weak, greasy dirt is cleaned not thorough.
The content of the invention
The technical problems to be solved by the invention:It is generally hydrophilic oleophobic property for Wiping material, the clearance to greasy dirt is poor,
Receive that oily power is low, dirt-removing power is weak, halfway drawback is cleaned to greasy dirt, there is provided a kind of preparation side for receiving greasy dirt Wiping material high
Method, the present invention, for raw material prepares transparent liquid, pure cotton is weaved cotton cloth first with citric acid, triethylene glycol monobutyl ester and p-methyl benzenesulfonic acid
It is immersed in transparent liquid, the structure that can be weaved cotton cloth to pure cotton is modified, makes the oil suction of cotton fiber and receive oily ability to strengthen, then profit
With the colloidal sol obtained after teos hydrolysis, pure cotton further oleophylic of weaving cotton cloth is modified, makes pure cotton fiber that there is very strong parent
Oiliness energy, the height for preparing of the present invention receives greasy dirt Wiping material, and with low cost, process is simple, oil sucting force is strong, and oil mass of receiving is high,
Oil product can be quickly absorbed, can be wiped in machine machine oil, the field such as water-oil separating is with a wide range of applications.
In order to solve the above technical problems, the present invention is using technical scheme as described below:
(1)To being separately added into 15~20g citric acids, 70~75g triethylene glycol monobutyls ester, 0.4~0.6g in four-hole boiling flask to toluene
Sulfonic acid and 50~70mL toluene, are put into oil bath pan, and 130~140 DEG C, insulated and stirred are warming up to 4~6 DEG C/min heating rates
3~4h of reaction, reaction is cooled to room temperature after terminating, and to the dropwise addition sodium hydroxide solution of mass fraction 5% in four-hole boiling flask, until
Regulation pH is 9.0~10.0, and 1~2h is stood after regulation, organic phase is collected after layering, the vacuum distillation at a temperature of 95~105 DEG C
20~30min, obtains transparent liquid liquid after distillation, standby;
(2)Weigh during 40~60g tetraethyl orthosilicates add there-necked flask, and to adding 100~120mL mass point in there-necked flask
Several 95% mass fraction ethanol solutions, are put into water-bath and are heated to 60~70 DEG C, and insulated and stirred mixes and add after 1~2h 0.5~
1.0g γ-methacryloxypropyl trimethoxy silane, continue 2~4h of stirring reaction, in the stage of reaction, every 30~
40min is cooled to room temperature, obtains colloidal sol to the ammoniacal liquor of 3~5mL mass fractions 10%, reaction are added dropwise in there-necked flask after terminating;
(3)The pure cotton for cutting 3~5 pieces of 20cm × 20cm is weaved cotton cloth, and pure cotton is weaved cotton cloth and is put into 40~60 DEG C of warm water, is dried in the air after washing
Dry, the pure cotton that will be washed after drying weaves cotton cloth in mass ratio 1:100 are immersed in above-mentioned colloidal sol, and pressure rolling is taken out after 10~15min of immersion,
Make pick-up rate for 70~80%, then place into and soak in colloidal sol, taken out after 5~10min of immersion, pressure rolling make pick-up rate for 50~
60%, the pure cotton after padding is weaved cotton cloth and is put into baking oven, and 5~10min is first heat-treated at a temperature of 90~100 DEG C, is then raised temperature to
130~150 DEG C of 2~4min of heat treatment, pure cotton after treatment are weaved cotton cloth and are put into 10~20min of cooling in clear water, are taken out after cooling and put
Enter in baking oven, 10~12h is dried at a temperature of 70~80 DEG C, obtain the modified pure cotton in surface and weave cotton cloth;
(4)Above-mentioned modified pure cotton is weaved cotton cloth in mass ratio 1:100 are immersed in step(1)It is standby in standby transparent liquid, and
To 0.1~0.3g ethylene imides are added in transparent liquid, 8~10h is placed at a temperature of being put into 0~5 DEG C, pure cotton is taken out after placement and is weaved cotton cloth,
Natural air drying, you can obtain height and receive greasy dirt Wiping material.
Obtained height of the invention receives greasy dirt Wiping material density for 100~150g/m2, oil absorbency is up to more than 90.2%, area
Shrinkage factor is 15~17%, and fracture strength is 4.26~5.04cN/dtex, and elongation at break is 30.59~38.56%, wiping
Pyatyi can be reached, pollutant holding capability is the 200~400% of deadweight, and average swelling rate is 3~5g/s.
Compared with other method, Advantageous Effects are the present invention:
(1)The height that the present invention is prepared receives greasy dirt Wiping material step simply, with low cost, products obtained therefrom oil suction easy to operate,
Oil absorbency is high;
(2)The height that the present invention is prepared receives greasy dirt Wiping material, and oil sucting force is strong, and oil mass of receiving is high, can quickly absorb oil product, can
Wiped in machine machine oil, the field such as water-oil separating is with a wide range of applications.
