Description

本発明は、自然塗料など、被塗装面に擦り込むようにして塗布する塗料に適した塗装用刷毛に関する。   The present invention relates to a coating brush suitable for a paint such as a natural paint applied by rubbing on a surface to be coated.

例えば、植物油や天然顔料などを主成分とした自然塗料は、被塗装面の木目に擦り込むようにして塗布するのが一般的である。このように、被塗装面に塗料を擦り込むようにして塗布するためには、腰の強い刷毛が必要である。
腰の強い毛としては豚毛が一般的で、自然塗料用としても豚毛の塗装用刷毛が一般に用いられていた。 For example, a natural paint mainly composed of vegetable oil or natural pigment is generally applied so as to be rubbed into the wood surface to be coated. Thus, in order to apply the paint so as to be rubbed against the surface to be coated, a firm brush is required.
Pig hair is generally used as a strong hair, and a brush for painting pig hair is generally used as a natural paint.

実用新案登録第３１２４９２７号公報Utility Model Registration No. 3124927

豚毛は腰が強く、上記したように木目などに塗料を擦り込むようにして塗装する用途に適しているが、豚毛は、他の獣毛と同様に耐摩耗性に劣るため、豚毛の刷毛は、塗料を擦り込むようにして用いる刷毛としては耐久性に問題があった。
そこで、豚毛に比べて耐摩耗性に優れた化繊の毛を用いることが考えられるとともに、太い化繊の毛を用いれば、豚毛と同等の強い腰を実現することができる。ところが、化繊の毛は有機溶剤に弱いという問題がある。 Pig hair is strong and suitable for applications where the paint is rubbed into the wood as described above, but since pig hair is inferior in wear resistance like other animal hair, Has a problem with durability as a brush used by rubbing the paint.
Therefore, it is conceivable to use synthetic fiber having better abrasion resistance than pork hair, and if thick synthetic fiber is used, a strong waist equivalent to pork hair can be realized. However, there is a problem that synthetic hair is weak against organic solvents.

ただし、自然塗料は、化学物質をほとんど含まないため、それ自体には有機溶剤もそれほど多く含まれていないが、使用後に乾燥した塗料を洗浄するためにはアルコールやシンナーなどの有機溶剤を使用しなければならない。このときには、洗浄用の有機溶剤によって化繊が侵されることがあるが、化繊の毛は、有機溶剤に侵されると腰が弱くなってしまうという問題があった。
この発明の目的は、特に強い腰を長期にわたって維持できる耐久性を備えた塗装用刷毛を提供することである。 However, natural paint contains almost no chemical substances, so it does not contain so much organic solvent. However, organic solvents such as alcohol and thinner are used to clean the dried paint after use. There must be. At this time, the synthetic fiber may be attacked by the organic solvent for cleaning, but there is a problem that the fiber of the synthetic fiber becomes weak when it is attacked by the organic solvent.
An object of the present invention is to provide a coating brush having durability that can maintain a particularly strong waist for a long period of time.

第１の発明は、ＰＥＴ（ポリエチレンテレフタレート）からなる直毛５５〜６５（重量％）、化繊からなるウェーブ毛１０〜２０（重量％）及び豚毛５〜３０（重量％）が混合され、少なくとも上記豚毛は他の毛よりも短くし、この豚毛の長さは、塗布時に刷毛部がたわんだ状態で、豚毛の先端が被塗装面に接触しないか、あるいは軽く接触する程度の長さにしていることを特徴とする。
なお、上記ＰＥＴからなる直毛、化繊からなるウェーブ毛及び豚毛以外の毛を含んで全体を１００（重量％）としてもよい。
第２の発明は、上記化繊からなるウェーブ毛がＰＢＴ（ポリブチレンテレフタレート）からなることを特徴とする。 In the first invention, straight hair 55 to 65 (% by weight) made of PET (polyethylene terephthalate), wave hair 10 to 20 (% by weight) made of synthetic fiber and 5 to 30 (% by weight) pig hair are mixed , and at least The above-mentioned pork hair is shorter than other hairs, and the length of this pork hair is such that the tip of the pig hair does not touch the surface to be painted or touches lightly when the brush part is bent at the time of application. It is characterized by that.
In addition, it is good also considering the hairs other than the straight hair which consists of said PET, the wave hair which consists of synthetic fibers, and pig hair as 100 (weight%).
A second invention is characterized in that the wave hair made of the above-mentioned synthetic fiber is made of PBT (polybutylene terephthalate).

第１の発明の塗装用刷毛は、腰の強い豚毛と化繊のなかで比較的剛性の高いＰＥＴからなる直毛とによって刷毛の腰を維持するようにしている。
そして、最も腰が強い豚毛の長さを他の毛よりも短くしているので、塗料を擦り込むようにした場合にも、塗装時に豚毛の先端が被塗装面に強く押し付けられることがない。このように、豚毛は被塗装面と強く摩擦されないため摩耗しにくい。
また、洗浄用の有機溶剤によって化繊の直毛の腰が弱くなったとしても、豚毛の腰が維持されているので、刷毛としての必要な腰の強さは維持されることになる。
さらに、化繊からなるウェーブ毛とキューティクルを備えた豚毛とによって、塗料の含み性も保持している。
従って、この発明の塗装用刷毛は、含み性も、腰の強さも同時に満足しながら、耐久性も備えた刷毛である。 The brush for painting according to the first aspect of the present invention maintains the waist of the brush by virtue of strong pork hair and straight hair made of PET having relatively high rigidity among the synthetic fibers.
And since the length of the toughest pig hair is shorter than other hairs, the tip of the pig hair can be strongly pressed against the surface to be painted even when rubbing the paint. Absent. In this way, pig hair is not easily rubbed against the surface to be coated, and thus is not easily worn.
Further, even if the straight hair of the synthetic fiber is weakened by the organic solvent for cleaning, the waist of the pig hair is maintained, so that the necessary waist strength as a brush is maintained.
Furthermore, the covering property of the paint is maintained by the wave hair made of synthetic fiber and the pig hair provided with the cuticle.
Accordingly, the painting brush of the present invention is a brush having durability while simultaneously satisfying the containment property and the strength of the waist.

第２の発明によれば、直毛を構成するＰＥＴよりも剛性の低いＰＢＴ繊維でウェーブ毛を構成することにより、刷毛全体のしなやかさを得ることができる。   According to 2nd invention, the softness of the whole brush can be obtained by comprising a wave hair with PBT fiber whose rigidity is lower than PET which comprises straight hair.

図１はこの発明の実施形態の塗装用刷毛の全体図である。FIG. 1 is an overall view of a painting brush according to an embodiment of the present invention. 図２は実施形態の各毛の混合割合を示した表である。FIG. 2 is a table showing the mixing ratio of each hair according to the embodiment. 図３は実施形態の化繊のウェーブ毛を示した図である。FIG. 3 is a view showing the synthetic wave hair of the embodiment. 図４は塗布時の刷毛部の状態を示した図である。FIG. 4 is a diagram showing a state of the brush portion at the time of application.

図１〜図３を用いてこの発明の実施形態を説明する。
この実施形態の塗装用刷毛は、図１に示すように、結束帯１で毛を束ねて刷毛部２を構成し、上記結束体１を取っ手３に固定したものである。この実施形態の取っ手３は、一端を二股にした木製の部材で、この二股状部分に上記結束帯１を挟み込んでから、針金４によって取っ手３に結束帯１を固定している。但し、取っ手３の材質や形状はこの実施形態に限定されないし、刷毛部２と取っ手３はどのような方法で固定してもかまわない。 An embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the painting brush according to this embodiment is obtained by bundling hairs with a binding band 1 to form a brush portion 2 and fixing the binding body 1 to a handle 3. The handle 3 of this embodiment is a wooden member having one end bifurcated, and the binding band 1 is fixed to the handle 3 by a wire 4 after the binding band 1 is sandwiched between the bifurcated portions. However, the material and shape of the handle 3 are not limited to this embodiment, and the brush portion 2 and the handle 3 may be fixed by any method.

また、上記刷毛部２は、図２に示す３種類の毛を混合して構成している。
つまり、刷毛部２は、ポリエチレンテレフタレート（ＰＥＴ）繊維からなる直毛と、化繊からなるウェーブ毛と、豚毛とを混合し、結束体１で束ねた毛束である。
また、上記ウェーブ毛は、図３に示すように波形を加えた毛である。
このウェーブ毛は、その製造過程において、歯車や型を押し付けて規則的な波形状を形成したものである。 The brush portion 2 is formed by mixing three kinds of hair shown in FIG.
That is, the brush portion 2 is a hair bundle in which straight hair made of polyethylene terephthalate (PET) fiber, wave hair made of synthetic fiber, and pig hair are mixed and bundled by the binding body 1.
Further, the wave hair is a hair to which a waveform is added as shown in FIG.
In the manufacturing process, the wave hair is formed by pressing a gear or a mold to form a regular wave shape.

そして、上記ウェーブ毛を構成する化繊の材質は特に限定されない。例えば、上記直毛を構成するＰＥＴのほか、ポリブチレンテレフタレート（ＰＢＴ）などを用いることができるが、刷毛の用途に応じて、腰の強さや塗料の種類などを基準に、その種類を選ぶことができる。
なお、ＰＢＴはＰＥＴよりも剛性が低い。具体的には、ＰＢＴ繊維の見かけヤング率は２２５０〜４６００（Ｎ／ｍｍ２）であり、ＰＥＴ繊維の見かけヤング率は１０７８０〜１９６００（Ｎ／ｍｍ２）である。
そのため、ウェーブ毛にＰＢＴを用いた場合には、刷毛部２のしなやかさを出すことができるし、ＰＥＴを用いた場合にはさらに腰を強くすることができる。 And the material of the synthetic fiber which comprises the said wave hair is not specifically limited. For example, polybutylene terephthalate (PBT) can be used in addition to PET constituting the straight hair, but depending on the use of the brush, the type should be selected based on the strength of the waist and the type of paint. Can do.
PBT has lower rigidity than PET. Specifically, the apparent Young's modulus of the PBT fiber is 2250-4600 (N / mm 2 ), and the apparent Young's modulus of the PET fiber is 10780-19600 (N / mm 2 ).
Therefore, when PBT is used for the wave hair, the flexibility of the brush portion 2 can be obtained, and when PET is used, the waist can be further strengthened.

また、この実施形態の塗装用刷毛では、図１、図４に示す上記結束帯１から露出した刷毛部２の全体の長さをＬ１とし、豚毛の長さＬ２を他の毛の長さよりも短くしている。具体的には、豚毛の長さＬ２を、刷毛部２の長さＬ１よりも数（ｍｍ）〜２０（ｍｍ）程度短くしている。
なお、この刷毛部２として用いる豚毛以外の毛の長さは、長さＬ１よりも短いものが混在していてもよいが、刷毛部２全体としての長さは、上記Ｌ１を確保している。 Moreover, in the brush for painting of this embodiment, the whole length of the brush part 2 exposed from the said binding band 1 shown to FIG. 1, FIG. 4 is set to L1, and the length L2 of pig hair is set from the length of other hair. Also shortened. Specifically, the length L2 of the pig hair is shorter than the length L1 of the brush part 2 by several (mm) to 20 (mm).
In addition, although the length of the hairs other than the pork used as the brush part 2 may be shorter than the length L1, the length of the brush part 2 as a whole ensures the above L1. Yes.

このように豚毛の長さＬ２を刷毛部２の長さＬ１よりも短くしたのは、図４に示す塗装時に、豚毛が被塗装面５に強く押し付けられて摩耗することがないようにするためである。
従って、豚毛の長さＬ２は、塗布時に刷毛部２がたわんだ状態で、豚毛の先端が被塗装面５に接触しないか、軽く接触する程度の長さに設定する。 The length L2 of the pig hair is made shorter than the length L1 of the brush portion 2 in this way so that the pig hair is not strongly pressed against the surface to be coated 5 and worn during the painting shown in FIG. It is to do.
Accordingly, the length L2 of the pig hair is set to such a length that the tip of the pig hair does not contact the surface to be coated 5 or lightly contacts with the brush portion 2 bent at the time of application.

上記した３種類の毛を混合して刷毛部２を構成するが、各毛の混合量は図２の表に示す混合量の範囲で設定する。そして、図２の表に示す範囲ならば、どのような組み合わせでも構わない。
但し、この実施形態の刷毛は、上記３種類の毛のみで刷毛部２の１００（重量％）を構成してもよいし、上記３種類の毛以外の毛を含んで１００（重量％）となるようにしてもよい。
例えば、各毛の混合量を、上記表に示す下限値とすると、その合計は７０（重量％）となるが、残りの３０（重量％）は、豚毛以外の天然毛や、ＰＥＴ以外の化繊からなる直毛などで構成することができる。
このように、図２に示す３種類の毛で、刷毛部２の７０（重量％）から１００（重量％）を構成し、１００（重量％）に足りない分は、別の毛を混合するようにしている。 The brush portion 2 is configured by mixing the above-described three kinds of hairs, and the amount of each hair is set within the range of the amount shown in the table of FIG. Any combination is possible as long as it is within the range shown in the table of FIG.
However, the brush of this embodiment may constitute 100 (% by weight) of the brush part 2 with only the three types of hairs, or 100% (% by weight) including hairs other than the three types of hairs. It may be made to become.
For example, when the mixing amount of each hair is the lower limit value shown in the above table, the total is 70 (% by weight), but the remaining 30 (% by weight) is natural hair other than pork hair or other than PET It can be composed of straight hair made of synthetic fibers.
As described above, the three types of hairs shown in FIG. 2 constitute 70 (% by weight) to 100 (% by weight) of the brush portion 2, and another hair is mixed if the amount is less than 100 (% by weight). I am doing so.

上記のように構成した刷毛部２を備えたこの実施形態の塗装用刷毛は、化繊の中で比較的剛性の高いＰＥＴからなる直毛と、豚毛とによって強い剛性を維持し、自然塗料を被塗装面５に擦り込むようにして塗布する作業に適している。
また、表面にキューティクルを有する豚毛と、化繊のウェーブ毛とによって、化繊の直毛だけで構成した刷毛と比べて多くの塗料を含むことができる。
従って、この実施形態の塗装用刷毛を用いれば、例えば、自然塗料などの塗装作業を効率よく行なうことができる。 The brush for painting of this embodiment provided with the brush part 2 configured as described above maintains strong rigidity by straight hair made of PET having relatively high rigidity in the synthetic fiber and pig hair, so that natural paint can be applied. It is suitable for the operation of applying it so as to rub against the surface 5 to be coated.
In addition, pork hair having a cuticle on the surface and waved hair of synthetic fiber can contain more paint than a brush composed only of straight fiber of synthetic fiber.
Therefore, if the coating brush of this embodiment is used, for example, a painting operation such as natural paint can be performed efficiently.

しかも、刷毛部２に含まれる豚毛は被塗装面５に塗料を擦り込むようにして塗布する塗装作業時に、被塗装面５に強く押し付けられることがないため摩耗しにくい。つまり、刷毛に強い腰を与える機能を備えた豚毛が、繰り返しの使用によって摩耗することがなく、刷毛の腰を長期にわたって維持することができる。
また、洗浄に用いる有機溶剤が、化繊の毛に影響を与え、ＰＥＴからなる直毛の腰を多少弱くしたとしても、摩耗しない豚毛がそれを補って、刷毛全体の腰を維持できる。 In addition, the pig hair contained in the brush portion 2 is not easily pressed against the surface to be coated 5 during the coating operation in which the paint is applied by rubbing the surface to the surface 5 to be painted, so that it is not easily worn. That is, the pig hair having the function of giving the brush a strong waist is not worn by repeated use, and the brush waist can be maintained for a long time.
Further, even if the organic solvent used for washing affects the hair of the synthetic fiber and the waist of the straight hair made of PET is somewhat weakened, the non-wearing pig hair can compensate for it, and the waist of the entire brush can be maintained.

さらに、図２の表に示した３種類の毛だけで１００（重量％）に満たない場合に混合する毛として、例えば馬毛などの天然毛を用いれば、毛の表面のキューティクルやウェーブが作る空間が塗料を保持し、含み性をよくすることができる。
そして、洗浄用の有機溶剤の影響で、上記化繊のウェーブ毛のウェーブが伸びてしまったとしても、耐溶剤性を有する上記天然毛が塗料の含み性を保持できるので、含み性も維持できる。 Furthermore, if natural hair such as horse hair is used as the hair to be mixed when the three kinds of hair shown in the table of FIG. 2 are less than 100% by weight, a cuticle or wave on the surface of the hair is produced. The space holds the paint and can improve the containment.
And even if the wave of the said synthetic fiber wave hair extends under the influence of the organic solvent for washing | cleaning, since the said natural hair which has solvent resistance can maintain the containment property of a coating material, the containment property can also be maintained.

なお、この実施形態の刷毛は、上記豚毛の長さＬ２を、刷毛部２の長さＬ１よりも短くして、刷毛部２の先端を被塗装面５に押し付けた状態で、豚毛が被塗装面５に強く押し付けられないようにしている点が特徴であるが、豚毛以外の毛はすべて同じ長さである必要はない。少なくとも豚毛が他の毛よりも短ければよいのであって、豚毛よりも短い毛が多少混ざっていてもかまわない。   The brush of this embodiment has the above-described pork hair length L2 shorter than the length L1 of the brush part 2 and the front end of the brush part 2 is pressed against the surface 5 to be coated. Although it is characterized in that it is not pressed strongly against the surface 5 to be coated, it is not necessary for all hairs other than pig hair to have the same length. It is sufficient that at least pork hair is shorter than other hairs, and hairs shorter than pork hair may be mixed somewhat.

この発明の塗装用刷毛は、擦り込むようにして塗布する自然塗料の塗装に適したものである。   The painting brush of this invention is suitable for painting natural paints applied by rubbing.
