Description

本発明は、自動車や電車等の車両用あるいは一般の家庭内等に敷設するカーペットにおいて、室内の騒音を吸収して十分な静粛性を確保できる通気性を有すると同時に止水性を有し、誤って零した飲み物等がカーペットの裏面にまで滲みこんで、カビを発生させ悪臭の元になったり、カーペットを通過して床に達した水分が床を傷めたりするのを防ぐ、通気性と止水性のあるカーペットに関するものである。なお、この明細書において、「止水性」とは、カーペットの上面に100ccの水を静かに乗せ、10分後に裏面に染み出さないことが確認されれば、止水性ありと判定した。   The present invention provides a carpet that is laid in vehicles such as automobiles and trains, or in general households, has air permeability that can absorb room noise and ensure sufficient quietness, and at the same time has water-stopping properties. Breathable drinks that penetrate to the back of the carpet generate mold and cause odors, and moisture that passes through the carpet and reaches the floor prevents damage to the floor. It relates to water-based carpets. In this specification, “water-stopping” was determined to be water-stopping if it was confirmed that 100 cc of water was gently placed on the top surface of the carpet and it did not ooze out to the back surface after 10 minutes.

振動や騒音を防止するために、従来から行なわれてきた技術としては、特許文献1のように、遮音性能に加え吸音性能も得られる車両用カーペットとして、カーペット表皮層の下側にTPE層を介して、フェルト層からなる吸音層を一体化したものを提案している。カーペット表皮層とフェルト層が主として吸音作用を奏し、TPE層が遮音層を奏するとしている。また出願人は特許文献2において、熱可塑性樹脂パウダーを用いた通気性のある接着層を介して、不織布からなる吸音層をカーペット表皮材と一体化したものを、特に吸音作用の優れた車両用カーペットとして提案している。   In order to prevent vibration and noise, as a conventional technique, as disclosed in Patent Document 1, a TPE layer is provided under the carpet skin layer as a carpet for vehicles that can obtain sound absorption performance in addition to sound insulation performance. Through which a sound absorbing layer made of a felt layer is integrated. The carpet skin layer and the felt layer mainly play a sound absorbing action, and the TPE layer plays a sound insulating layer. In addition, in the patent document 2, the applicant of the present invention is a vehicle in which a sound absorbing layer made of a nonwoven fabric is integrated with a carpet skin material through a breathable adhesive layer using a thermoplastic resin powder, particularly for a vehicle having an excellent sound absorbing effect. Proposed as a carpet.

しかしながら、特許文献1では、遮音層が止水性を有するものの、遮音層で反射する音を吸収できず、吸音性能の劣るものであった。また、特許文献2では、吸音性能に優れた車両用カーペットであるが、止水性能を備えたものではなかった。   However, in Patent Document 1, although the sound insulation layer has a water-stopping property, the sound reflected by the sound insulation layer cannot be absorbed and the sound absorption performance is inferior. Moreover, in patent document 2, although it is the carpet for vehicles excellent in the sound absorption performance, it was not what was equipped with the water stop performance.

本発明は、かかる技術的背景に鑑みてなされたもので、カーペットの上側や下側から入る騒音に対して優れた吸音性能を発揮し、室内の静粛性を確保することのできるカーペットであって、かつ、止水性を有し、誤ってカーペット上に零した飲み物等がカーペットの裏面にまで滲みこんで、カビを発生させ悪臭の元になったり、カーペットを通過して床に達した水分が床を傷めたりすることのないカーペットを提供するものである。   The present invention has been made in view of such a technical background, and is a carpet that exhibits excellent sound absorption performance against noise entering from the upper side and the lower side of the carpet and can ensure the quietness of the room. In addition, drinks that have water-stopping properties, accidentally spilled onto the carpet, ooze up to the back of the carpet, generating mold and causing bad odor, or moisture that has passed through the carpet and reached the floor It provides carpets that do not damage the floor.

本発明者らは、このような課題を解決するために鋭意検討の結果、撥水剤を含有した水系樹脂エマルジョンを、表皮材層と吸音層の重ね合わせ面に塗布して接着樹脂層とすることにより、止水性と吸音性のあるカーペットが得られることを見出し本発明に到達した。本発明は、以下の手段を提供する。   As a result of intensive studies to solve such problems, the present inventors applied a water-based resin emulsion containing a water repellent to the superposed surface of the skin material layer and the sound absorbing layer to form an adhesive resin layer. As a result, it was found that a carpet having water-stopping properties and sound-absorbing properties can be obtained, and the present invention has been achieved. The present invention provides the following means.

[1]表皮材層と、吸音層とが、接着樹脂層を介して一体化されてなるカーペットにおいて、撥水剤を含有した水系接着樹脂エマルジョンを、表皮材層と吸音層の重ね合わせ面に塗布して接着樹脂層としたことを特徴とするカーペット。 [1] In a carpet in which a skin material layer and a sound absorbing layer are integrated via an adhesive resin layer, a water-based adhesive resin emulsion containing a water repellent is applied to the superposed surface of the skin material layer and the sound absorbing layer. A carpet characterized by being applied to form an adhesive resin layer.

[2]前記水系接着樹脂エマルジョンとして、接着樹脂100質量部に対して、撥水剤を3〜10質量部の割合で含有した水系接着樹脂エマルジョンを塗布し、450〜800g/m(乾燥後)の接着樹脂層としたことを特徴とする前項1に記載のカーペット。 [2] As the aqueous adhesive resin emulsion, an aqueous adhesive resin emulsion containing 3 to 10 parts by weight of a water repellent is applied to 100 parts by weight of the adhesive resin, and 450 to 800 g / m 2 (after drying) The carpet according to item 1 above, wherein the adhesive resin layer is a

[3]前記撥水剤が、フッ素系撥水剤、シリコーン樹脂系撥水剤等から選ばれる少なくとも1種の撥水剤であることを特徴とする前項1又は2に記載のカーペット。 [3] The carpet according to item 1 or 2, wherein the water repellent is at least one water repellent selected from a fluorine-based water repellent, a silicone resin-based water repellent, and the like.

[4]前記表皮材層がニードルパンチカーペットあるいはタフテッドカーペットからなり、前記吸音層が不織布からなり、前記接着樹脂層を介して一体化したときのカーペット全体の通気度が、1〜15(cm/cm・秒)で止水性のあることを特徴とする前項1乃至3のいずれか一項に記載のカーペット。 [4] The skin material layer is made of a needle punch carpet or tufted carpet, the sound absorbing layer is made of a nonwoven fabric, and the air permeability of the entire carpet when integrated through the adhesive resin layer is 1 to 15 (cm The carpet according to any one of the preceding items 1 to 3, wherein the carpet is water-stopping at 3 / cm 2 · sec).

[1]の発明では、表皮材層と、吸音層とが、接着樹脂層を介して一体化されてなるカーペットにおいて、撥水剤を含有した水系接着樹脂エマルジョンを、表皮材層と吸音層の重ね合わせ面に塗布して接着樹脂層としたので、接着樹脂層は、フィルムのような非通気性の層ではなく、表皮材層から吸音層まで通気性が確保され、また、接着樹脂層に撥水剤を含有させているので接着樹脂層表面に到達した液体は、接着樹脂層に直ぐに染み込むことなく接着樹脂層上に保持されることから、吸音性能と止水性能のあるカーペットとすることができる。また、通気性があるので、カーペット裏面に床下からの湿気が貯まりカビ等の発生するのを防ぐことができる。   In the invention of [1], in the carpet in which the skin material layer and the sound absorbing layer are integrated via the adhesive resin layer, the water-based adhesive resin emulsion containing the water repellent agent is used for the skin material layer and the sound absorbing layer. Since the adhesive resin layer is applied to the overlapping surface, the adhesive resin layer is not a non-breathable layer such as a film, but air permeability is secured from the skin material layer to the sound absorbing layer. Because it contains a water repellent, the liquid that has reached the surface of the adhesive resin layer is retained on the adhesive resin layer without immediately soaking into the adhesive resin layer, so the carpet should have sound absorption performance and water stopping performance. Can do. Moreover, since it has air permeability, it is possible to prevent moisture from the floor from accumulating on the back surface of the carpet and generating mold and the like.

[2]の発明では、水系接着樹脂エマルジョンとして、接着樹脂100質量部に対して、撥水剤を3〜10質量部の割合で含有した水系樹脂エマルジョンを用いるので、十分な止水性能が確保され、また、450〜800g/m(乾燥後)の接着樹脂層とするので、接着力を維持したままで通気性も有することができ、吸音性能と止水性能のあるカーペットとすることができる。 In the invention of [2], as the water-based adhesive resin emulsion, a water-based resin emulsion containing 3 to 10 parts by weight of a water repellent with respect to 100 parts by weight of the adhesive resin is used, so that sufficient water stopping performance is ensured. In addition, since it is an adhesive resin layer of 450 to 800 g / m 2 (after drying), it can have air permeability while maintaining the adhesive force, and can be made into a carpet having sound absorbing performance and water stopping performance. it can.

[3]の発明では、前記撥水剤が、フッ素系撥水剤、シリコーン樹脂系撥水剤等から選ばれる少なくとも1種の撥水剤であるので、水系接着樹脂エマルジョンとの相溶性もよく、均一な撥水性能を有する接着樹脂層を形成することができ、止水性能のあるカーペットとすることができる。   In the invention of [3], the water repellent is at least one water repellent selected from a fluorine-based water repellent, a silicone resin-based water repellent, and the like, and therefore has good compatibility with the water-based adhesive resin emulsion. Thus, an adhesive resin layer having uniform water repellency can be formed, and a carpet having water stopping performance can be obtained.

[4]の発明では、前記表皮材層がニードルパンチカーペットあるいはタフテッドカーペットからなり、前記吸音層が不織布からなり、前記接着樹脂層を介して一体化したときのカーペット全体の通気度が、1〜15(cm/cm・秒)であるので、表皮材層と、不織布からなる吸音層とを通気性を確保した状態で強固に一体化することができ、吸音性能と止水性能のあるカーペットとすることができる。 In the invention of [4], the skin material layer is made of needle punched carpet or tufted carpet, the sound absorbing layer is made of non-woven fabric, and the air permeability of the entire carpet when integrated through the adhesive resin layer is 1 -15 (cm 3 / cm 2 · sec), the skin material layer and the sound absorbing layer made of nonwoven fabric can be firmly integrated in a state where air permeability is ensured. It can be a carpet.

Is applied to the superposed surface of the skin material layer 2 and the sound absorbing layer 3 to form an adhesive resin layer 4, which ensures air permeability from the skin material layer 2 to the sound absorbing layer 3, and further contains a water repellent in the adhesive resin layer 4. Therefore, when the liquid such as water or coffee spilled on the carpet passes through the skin material layer 2 and reaches the surface of the adhesive resin layer, the liquid does not soak into the adhesive resin layer 4 and is retained on the adhesive resin layer. Therefore, a carpet having sound absorbing performance and water stopping performance can be obtained.

The application amount of the adhesive resin layer 4 is preferably in the range of 450 to 800 g / m 2 (weight after drying). If it is less than 450 g / m < 2 >, the adhesive strength of the skin material layer 2 and the sound absorption layer 3 cannot be obtained, and water-stopping property is not ensured. If it exceeds 800 g / m 2 , the adhesive resin layer 4 forms a film, and the air permeability of 1 to 15 (cm 3 / cm 2 · sec) in the thickness direction of the target carpet cannot be ensured. Further, it is not preferable in terms of cost.
