Description

本発明は、洗車用ブラシに関し、更に詳しくは、自動車の塗装表面や窓ガラス・フロントガラス、タイヤ等の外装表面を傷つけることなく高い洗浄力を備え、更に、耐久性・防火性（難燃性・自己消火性）にも優れた洗車用ブラシに関する。 The present invention relates to a car wash brush. More specifically, the present invention has a high detergency without damaging the exterior surface of an automobile paint surface, window glass, windshield, tire, etc. -It relates to a car wash brush that has excellent self-extinguishing properties.

ガソリンスタンド等で多用されている洗車用ブラシに関し、特許文献１に記載の洗車用ブラシ用の洗浄片が知られている。これは、洗車用ブラシを構成する多数の柔軟な洗浄片を、メタロセン触媒を用いてα−オレフィンを共重合させた直鎖状低密度ポリエチレン樹脂を含む樹脂の発泡体から構成するようにしたものである。
更に、特許文献２に記載の炭素繊維を含む洗車用ブラシや、本出願人によって出願された特許文献３，４に記載の炭素繊維束を用いたブラシが知られている。 A cleaning piece for a car wash brush described in Patent Document 1 is known for a car wash brush frequently used at a gas station or the like. This is a structure in which a large number of flexible cleaning pieces constituting a car wash brush are made of a resin foam containing a linear low-density polyethylene resin copolymerized with an α-olefin using a metallocene catalyst. It is.
Furthermore, a brush for car wash containing carbon fibers described in Patent Document 2 and a brush using carbon fiber bundles described in Patent Documents 3 and 4 filed by the present applicant are known.

しかしながら、特許文献１に記載の洗車用ブラシの洗浄片は、車体を損傷させることがない点では優れているものの、洗浄力が弱いという問題がある。
また、上記特許文献２〜４に記載されている炭素繊維を用いたブラシは、耐熱性に優れているが、燃えやすく、防火性（難燃性・自己消化性）が良くない。尚、本明細書においては、防火性とは、燃えにくい性質又は不燃性を包含する意味である。また、本明細書においては、防火性に含まれる性質のうち、難燃性・自己消化性は、同義で用いている。そして、難燃性・自己消火性は、燃えにくいというだけではなく、火が付いた状態で火元に置いておくと燃焼し続けるが、火を遠ざけると自然に鎮火する性質、すなわち、延焼を最小限にくい止める性質を指す。
更に、一般的に炭素繊維は硬いため、加工せずに洗車用ブラシとして用いると車体を傷つけるという問題もある。 However, although the washing piece of the car wash brush described in Patent Document 1 is excellent in that it does not damage the vehicle body, there is a problem that the washing power is weak.
Moreover, although the brush using the carbon fiber described in the said patent documents 2-4 is excellent in heat resistance, it is easy to burn and fire resistance (a flame retardance and self-digestibility) is not good. In addition, in this specification, fireproofing is the meaning including the property which is hard to burn, or nonflammability. Further, in the present specification, among the properties included in the fire resistance, flame retardancy and self-digestibility are used synonymously. In addition, flame retardancy and self-extinguishing properties are not only difficult to burn, but they will continue to burn if left in the fire with the fire on, but will naturally extinguish when the fire is moved away, that is, spread fire. It refers to the nature of stopping it to a minimum.
Furthermore, since carbon fiber is generally hard, there is a problem that the vehicle body is damaged when used as a car wash brush without being processed.

そこで、車体を損傷させないだけではなく、洗浄力が高い洗車用ブラシが求められている。また、コスト等を低減させるべく、耐久性の高い洗車用ブラシが求められてる。更に、ガソリンスタンド等において万が一火災が発生した場合に被害を最小限に食い止めるべく、防火性（難燃性・自己消火性）に優れた洗車用ブラシが求められている。 Therefore, there is a need for a car wash brush that not only damages the vehicle body but also has high cleaning power. Further, in order to reduce the cost and the like, a highly durable car wash brush is required. Further, there is a need for a car wash brush with excellent fire resistance (flame retardant and self-extinguishing properties) in order to minimize damage in the event of a fire at a gas station or the like.

本発明は、上記問題点を解決するためになされたものであり、その目的は、車体を損傷させることなく高い洗浄力を備え、かつ、耐久性・防火性（難燃性・自己消火性）に優れた洗車用ブラシを提供することにある。 The present invention has been made in order to solve the above-mentioned problems, and its purpose is to provide a high detergency without damaging the vehicle body, and to provide durability and fire resistance (flame retardant and self-extinguishing properties). The object is to provide an excellent car wash brush.

上記課題を解決するために、本発明者等は、車体を損傷させることなく高い洗浄力を備え、かつ、耐久性・防火性（難燃性・自己消火性）に優れた洗車用ブラシを得るために鋭意研究を行ったところ、洗車用ブラシの洗浄片を軟質塩化ビニル樹脂を主成分として含む高分子複合材料からなるフィラメントによって構成すればよいことを知見するに至った。本発明は、かかる知見に基づいてなされたものである。
本発明に係る洗車用ブラシは、軟質塩化ビニル樹脂を主成分として含む高分子複合材料からなるフィラメント状の洗浄片からなることを要旨とする。
この場合に、前記洗浄片は、断面多角形状、断面星形形状、断面の周囲に凹凸が施された形状、又は、断面の周囲に鋭角部分が施された形状であることが望ましい。 In order to solve the above-mentioned problems, the present inventors obtain a car wash brush having high cleaning power without damaging the vehicle body and having excellent durability and fire resistance (flame retardant and self-extinguishing properties). As a result of extensive research, the inventors have come to know that the cleaning piece of a car wash brush may be composed of a filament made of a polymer composite material containing a soft vinyl chloride resin as a main component. The present invention has been made based on such knowledge.
The gist of the brush for car washing according to the present invention is made of a filament-shaped cleaning piece made of a polymer composite material containing a soft vinyl chloride resin as a main component.
In this case, it is desirable that the cleaning piece has a polygonal cross-section, a star-shaped cross-section, a shape with irregularities around the cross-section, or a shape with an acute angle portion around the cross-section.

本発明に係る洗車用ブラシは、軟質塩化ビニル樹脂を主成分として含む高分子複合材料からなるフィラメント状の洗浄片からなるものであるから、車体を損傷させることなく高い洗浄力を備え、かつ、耐久性・防火性（難燃性・自己消火性）に優れるという効果がある。 The car wash brush according to the present invention is composed of a filament-shaped cleaning piece made of a polymer composite material containing a soft vinyl chloride resin as a main component, and thus has a high cleaning power without damaging the vehicle body, and It has the effect of being excellent in durability and fire resistance (flame retardant and self-extinguishing properties).
