The present invention relates to a coating method of a natural palmyra fiber coating brush, and more particularly, to coat the thinning of the brush made of natural palmyra fiber material with a synthetic polymer compound to have higher elasticity while maintaining the properties of the natural palmyra fiber. It relates to a coating method of a natural palmyra fiber coating brush, characterized in that one.

Generally, conventional natural Palmyra fiber brushes for cleaning stairs or floors of a building are formed in the hair follicles 3 formed on the body 1 and the lower surface 6 of the body, as shown in FIGS. 1 and 2. Multiple hair thinning (2) is composed of the inserted form. Natural palmyra fiber brushes require higher wear resistance and higher elasticity in order to remove contaminants contaminated on the stairs or floors of buildings, while natural palmyra fibers are collected from palmy palm trees in the tropics. Since the processed fiber is made of the material, hair thinning (2) is abrasion-resistant, but the elasticity of the fiber is weak, so that when the cleaning force is continuously applied, the thinning (2) of the hair is easily bent and lying down or Thinning (2) easily falls out of the hair follicles (3) of the body, such that there is a problem that the brush is easily damaged, but there is no development for this.

Therefore, in order to solve the above problems, the present invention is to coat the seedlings of natural Palmyra fibers with a synthetic polymer compound, thereby improving the elasticity and durability of the seedlings while maintaining the unique properties of natural Palmyra fibers as well as cleaning Even if you apply force to the upper part of the brush body, the thinning of the bristles easily bends easily, and the thinning of the bristles is not easily separated from the follicles. In addition, the object of the present invention is to provide a coating method of a natural Palmyra fiber coating brush, which exhibits excellent cleaning power and is easy to remove foreign substances.

In another aspect, the present invention is impregnated in the synthetic polymer compound impregnation solution to the lower surface of the natural palmyra fiber brush in which the hair follicles are formed, and the thin film inserted into the follicles is sufficiently impregnated in the impregnation solution and then taken out from the synthetic polymer compound impregnation solution When the hair thinning of the natural palmyra fiber brush is dried to the upper side and dried, the synthetic polymer compound impregnated liquid coated on the hair thinning flows down and penetrates into the hair follicles, so that the hair thinning does not easily fall out from the hair follicles. The present invention provides a coating method of a natural Palmyra fiber coating brush.

The present invention for solving the above problems is coated with a synthetic polymer compound of the hair thinning of the brush made of natural palmyra fiber material with a natural palmyra fiber coating, characterized in that to have a higher elasticity while maintaining the properties of the natural palmyra fiber It relates to a coating method of the brush.

The natural Palmyra fiber coating brush according to the present invention is impregnated with a synthetic polymer compound impregnation solution (hereinafter referred to as 'impregnation solution') prepared by mixing 3.0-10.0 wt% of the synthetic polymer compound and 90.0-97.0 wt% of the organic solvent, followed by drying. It is characterized in that.

As the synthetic polymer compound usable in the present invention, one of synthetic resins or synthetic rubbers may be selected and used. The present invention is to form a thin film on the surface of the natural fiber material of the brush made of natural palmyra fibers of the synthetic resin or synthetic rubber to increase the elastic strength while maintaining the original properties of natural palmyra fibers.

The synthetic polymer compound serves to improve the elasticity and durability by coating the hair thinning of the natural palmyra fibers, the preferred mixing amount is 3.0 to 10.0% by weight. And the organic solvent dissolves the synthetic resin, serves to adjust the viscosity of the impregnation liquid, the preferred mixing amount is 90.0 to 97.0% by weight.

When the content of the synthetic polymer compound is less than 3.0% by weight or the content of the organic solvent is more than 97.0% by weight, the content of the synthetic polymer compound is relatively insufficient compared to the content of the organic solvent, so that the elasticity of the seedlings of the natural Palmyra fibers When the mechanical strength such as wear resistance is lowered and the content of the synthetic polymer compound exceeds 10.0% by weight or the content of the organic solvent is less than 90.0% by weight, the viscosity of the impregnating solution is increased due to the excessive content of the synthetic polymer compound. There is a possibility that the workability is poor and the thinning of the seedlings becomes entangled with each other when drying the seedlings of the natural Palmyra fibers.

The synthetic resin usable in the present invention is preferably selected from xylene resin, polyester resin, polyamide resin, polyethylene resin and polyvinyl chloride resin.

Synthetic rubber usable in the present invention is preferably selected from one of butadiene rubber, nitrile rubber, butyl rubber, chloroprene rubber,

Organic solvents usable in the present invention include acetone, benzene, toluene, xylene, methyl ethyl ketone, isobutyl methyl ketone, ethyl acetate, butyl acetate, n-pentane, n-hexane, cyclohexane, methylcyclohexane, dichloromethane or One or more organic solvents selected from trichloroethylene were used

And the coating method of the natural palmyra fiber coating brush according to the present invention will be described in detail with reference to the accompanying drawings (Figs. 3a to 4).

Iii) preparing an impregnation solution 4 by mixing 3.0-10.0 wt% of the synthetic polymer compound and 90.0-97.0 wt% of the organic solvent; (impregnation step, see FIG. 3A).

Ii) impregnating the whole hair thinning layer 2 of the natural Palmyra fiber brush soaked in the impregnation liquid 4 (impregnation step, see Fig. 3b).

Iii) removing the natural Palmyra fiber brush impregnated in step ii) from the impregnation solution 4 and drying at room temperature with the hair thinning layer 2 facing upward; (drying step, see FIG. 3C)

The hair thinning (2) of the natural Palmyra fiber brush is coated on the synthetic polymer compound.

The synthetic polymer compound of step iii) may be used by selecting one of synthetic resin or synthetic rubber.

In the step iii), when the hair thinning (2) to the top to dry, the impregnation liquid (4) coated on the thinning thinning (2) flows down into the hair follicle (3) of the main body (1) It is a feature of this process that the hair thinning (2) is not easily separated from the hair follicles (3) because it is cured.

In addition, the synthetic polymer compound and the organic solvent which can be used in the present coating process have been described above.

Hereinafter, the present invention will be described in detail by way of examples.

(Examples 1 to 4)

Next, after the impregnation liquid was prepared according to the composition ingredients in Table 1, the thin palmetto fiber brush was impregnated with thin hairs, and then naturally dried at room temperature.

(Comparative Examples 1 to 5)

Comparative Example 1 was used as the natural palmyra fiber hair thinning, Comparative Examples 2 to 5 impregnated the hair thinning of the natural palmyra fiber brush after preparing the impregnation liquid according to the composition ingredients of the following [Table 1] as in the above Example After taking out, it was naturally dried at room temperature.

(How to measure)

1) wear rate

Wearing a rotary cleaner equipped with a natural Palmyra fiber coating brush while spraying water on the same concrete surface under the same conditions, applying 20 kg of load (rotary cleaner weight) for 20 minutes at a rotation speed of 180 rpm, and then wearing down thinning wool (%). Was measured according to the following equation.

2) seedlings

After 1 hour (cleaning time 20 minutes, 3 times) under the same conditions as above, it was determined by visually observing the arrangement state of the seedling thinning of the natural Palmyra fiber coating brush.

Criteria for judging the seedling arrangement are as follows.

-If there is no abnormality in the arrangement of thinning hair 1

-10 to 30% tipping in the array of seedlings 2

-If there is more than 30% tipping in the array of seedlings 3

As shown in Table 2, Examples 1 to 4 have less abrasion rate of hair thinning compared to Comparative Examples 1 to 5, and thus have excellent abrasion resistance, and because the elastic force of hair thinning is high, the arrangement of hair thinning is not directed to one side. Good alignment was seen. In particular, the brush manufactured using natural Palmila fiber without coating a synthetic resin or synthetic rubber as in Comparative Example 1 has a high wear rate compared to Examples 1 to 4, not only wear resistance is poor, but also the elasticity of the natural Palmila fiber is weak Because of this phenomenon, the arrangement of the thinning of the seedlings was caused to be pulled to one side.

On the other hand, in the case of Comparative Examples 2 and 4, the content of melamine resin and CR rubber is low, so that the coating effect on the natural Palmyra fiber material is less, and the wear rate is higher than that of Examples 1 to 4, resulting in poor wear resistance and elasticity of hair thinning. It was also possible to confirm that some arrangement of the seedling thinning was caused by the fall of the seedlings. In Comparative Examples 3 to 5, the seedling thinning had the same level of performance as those of Examples 1 to 4, but the melamine resin and the CR rubber Because the content of is too high, the hair thinning of the natural Palmyra fiber material becomes too hard, so the wear rate is high, and wear resistance is low. The efficiency of cleaning is not only inconvenient, but also inconvenient due to the entanglement of thinning of wool during cleaning. There was also a problem of low efficiency.

The present invention can be produced in various forms without the limitation of the form of the natural palmyra fiber coating brush, such as square brush brush, circular brush brush.

The present invention according to the above structure is coated by the thinning of the thinning of the natural palmyra fibers with a synthetic polymer compound, the elasticity and durability of the thinning of the thinnings of the natural palmyra fibers is improved, so the tendency of seedling thinning appeared in the conventional natural palmyra fiber brush In addition, the work efficiency is not only improved because the thinning of the seedling thinning does not occur, and there is an economical advantage since the service life is extended than the conventional natural palmyra fiber brush.
