Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid composition for imparting luster and lubricity to be used for a polishing agent for automobiles, furniture and floors, and a lubricant for skis. It relates to an impregnated wet wiper. [0002] Wax is a harmless and inexpensive polishing agent having water repellency, moisture proofness, gloss and lubricity, and is used as a polishing agent and lubricant for automobiles, furniture, shoes, floors and the like. I have. It is known that these forms are divided into a paste type and a liquid type, and are divided into an aqueous type and a solvent type depending on the type of the solvent. [0003] However, the paste type contains a dispersant for dispersing the wax. For this reason, the water resistance is poor, and it takes time to evaporate water and the like,
After wax is applied, it does not appear glossy and cannot be used immediately as a lubricant. The liquid type is obtained by dissolving wax in a petroleum fraction containing chlorine-based solvent, normal hexane, and normal heptane as a main component, but this type of solvent has insufficient solubility, Is deposited. In addition, there is also a problem that a solvent having a high solubility gels. Since the amount of wax at the time of application cannot be increased, gloss and lubricity are insufficient. [0004] In addition, the wax becomes harder as the molecular weight increases, so that the wax exhibits lubricity and is excellent in abrasion resistance. For this reason, wax can be used as a lubricant, but there is a problem that as the molecular weight increases, the solubility in organic solvents further worsens. The solubility of wax tends to increase as the affinity between the wax and the solvent increases, but on the other hand, the evaporation rate of the solvent is not only related to the heat of evaporation and the boiling point, but also because the affinity between the solvent and the wax is a major factor. Solvents having a strong affinity with the solvent evaporate slowly, resulting in poor drying properties. When the above-mentioned chlorine-based solvent, normal hexane or normal heptane is used, there is a problem that the affinity between the solvent and the wax is strong, the evaporation rate is low, and the solvent does not evaporate, so that the solvent cannot be used immediately after wax application. SUMMARY OF THE INVENTION [0005] The present invention provides a quick drying, glossy and lubricious wax composition and a wet wiper impregnated with the wax composition. [0006] That is, the present invention relates to a method for preparing a puffin wax from 80 to 90 parts by weight of cycloalkane.
10 parts by weight of the liquid composition was woven with acrylic microfiber
A wet wiper characterized by impregnating cloth.
You. The present invention will be described in more detail. The cycloalkane in the present invention preferably has a basic skeleton of 5 to 6 carbon atoms, and may have an alkyl group introduced into the basic skeleton. In this case, the alkyl group to be introduced includes a methyl group, an ethyl group and a propyl group. Among them, methylcycloalkane and ethylcycloalkane are preferable, and methylcyclohexane and ethylcyclohexane each having 6 basic skeleton carbon atoms are more preferable. The paraffin wax according to the present invention is a crystalline paraffin separated and refined from petroleum and having a melting point of 4%.
It is preferably from 0 ° C to 70 ° C, more preferably 50 ° C
To 60 ° C. are preferred. In particular, when used as a lubricant, the melting point of wax is proportional to the molecular weight, so it is important to use it at a high melting point. In this case, if it is used at a melting point of 55 ° C. or higher, a low coefficient of static friction can be obtained. The liquid composition obtained by dissolving the above paraffin wax in cycloalkane is impregnated in a carrier to obtain a wax-containing wet wiper. As the carrier in the present invention, any carrier can be used as long as it can impregnate and hold a liquid composition in which paraffin wax is dissolved in cycloalkane, but as a function, the absorbed one is moved to the coated surface by rubbing. It is preferable to use a material which has a high absorbing power and a high holding ability and does not stick to the surface of the carrier after impregnation. Specific examples include fabric, paper, felt, foam, sponge and cork.
The fibrous material may be, for example, cellulose, wool, silk, acrylic, polyester, PP, PE, nylon, or the like. A synthetic fiber-based nonwoven fabric having a lipophilic group can sufficiently impregnate the liquid wax composition.
Among synthetic fibers, acrylic fibers have both a hydrophilic group and a lipophilic group, and therefore have a high holding capacity for the liquid wax composition and a good impregnation state. Also, among the acrylic fibers, the non-woven acrylic non-woven fabric obtained by micro-dividing the easily splittable acrylic fibers by columnar flow treatment and entangled is entangled with the ultra-fine fibers divided only in the surface layer portion, and the inside is divided. It has a porous structure with many voids made of fibers that are not made, so the internal holding capacity is particularly high.Furthermore, the fibers have an ultra-fine and sharp cross section, so that they have good adhesion and excellent wiping performance. It is suitable for the carrier of the present invention. The wet wiper of the present invention is conveniently packaged individually in an aluminum foil bag to suppress evaporation. Example 1 Paraffin wax 135 (melting point 58 ° C.,
Was dissolved in methylcyclohexane. The dissolution rate is measured by taking paraffin wax (1 g) in a screw bottle, dissolving it in an oven, making the shape constant, and then weighing. A solvent (2.5 ml) is placed in the screw bottle, and shaken for 2 hours with a shaker to dissolve the wax. After draining, oven (10
5 ° C.) for 1 hour and then in a vacuum dryer (150 ° C.) for 2 hours to evaporate the remaining solvent. After allowing to cool, the weight is weighed, and the dissolution rate is calculated from the amount of the dissolved wax obtained by removing the amount of the residue from the original amount. The dissolution rate was 11.0%. Comparative Example 1 The same paraffin wax 135 as in Example 1
, The following various dissolution rates were measured in the same manner as in Example 1. The results were 7.6% of trichloroethane, 1.5% of dichloromethane (more than chlorine solvent), 8.9% of normal hexane, and 7.6% of normal heptane. Example 2 Paraffin wax 115 (melting point 47 ° C.,

Met. The smaller the value of the coefficient of static friction, the higher the slipping effect. Example 4 Paraffin wax 1 used in Example 3
A wet wiper using 35 wax was applied to a polyethylene piece (20 mm × 70 mm, 1 mm thick), and the contact angle (°) with water was measured with a contact angle meter (CA-D type Kyowa Interface Chemistry). This value is used as a blank value. next,
A load of 240 g was applied and a 6 cm wide roll (20 mm /
Rubs the wax on the application surface for 30 seconds. This operation is repeated three times, and the contact angle (°) between water and the piece of polyethylene is measured each time. Paraffin wax 115
(Melting point: 47 ° C.), a wet wiper similar to that of Example 3 was produced as a trial, and the contact angle between the wax-coated polyethylene piece and water was measured by the same test as described above. The abrasion resistance of the wax depending on the molecular weight (the melting point is proportional to the molecular weight) was examined. The smaller the contact angle, the lower the water repellency, which indicates the peeling of the wax. The results are shown below. The contact angle (°) of the paraffin wax 135 and the paraffin wax 115 is 10

4 and 84.3, 92.9 and 83.1 for the third time. Example 5 An acrylic ultrafine fiber nonwoven fabric was immersed in a wax solution, and the absorbance (% by weight) of the nonwoven fabric was measured.
The test was performed according to JIS L1018. The nonwoven fabric is sized to a test piece (7.5 cm × 7.5 cm) and weighed. A weight was attached to one end of the test piece, dropped into a dipping soda containing a wax solution, and immersed for 20 minutes.
A load of 6 kg is applied from above the scissors between the dried blotting papers for 2 seconds, and the test piece is immediately weighed to calculate the absorption rate. This test shows the high absorbency and high solution holding capacity of the synthetic fiber nonwoven fabric. The result is 122
(%)Met. Comparative Example 3 The same operation was performed using a pulp nonwoven fabric and a cellulosic fiber nonwoven fabric. The results were 49 and 26%. The composition of the present invention is a liquid wax for imparting gloss and lubricity. The wet wiper impregnated with the composition is composed of a conventional chlorine-based solvent and a main component of a petroleum fraction. Since the amount of wax that could not be completely dissolved with certain normal hexane and normal heptane is dissolved, glossiness can be enhanced. In addition, since high molecular weight wax which could not be dissolved with a conventional solvent can be dissolved, both lubricity and abrasion resistance of the wax can be improved. In addition, it has become possible to improve the operability in work, such as higher solvent evaporating property and better drying property as compared with conventional ones. For this reason, as a particularly suitable application, a liquid wax or a wet wiper-shaped wax has a low effect due to its small molecular weight, and has a problem in workability because the solvent is difficult to evaporate. Now it can be used as well. In addition, when the acrylic microfiber nonwoven fabric is used as a carrier, the content of the wax liquid composition is increased and the wax liquid composition is held inside, so that the carrier is not sticky and has a good feeling in use. The ultra-fine fibers on the surface have characteristics that are not present in conventional wet wipers, such that the fibers have an acute-angled cross section, so that the adhesiveness of the application surface is excellent and the wiping performance is high.
