Abstract
Description
本発明は、融雪用塗料組成物に関する。 The present invention relates to a snow-melting paint composition.
降雪量の多い寒冷地では、冬の路面凍結や積雪が交通障害の要因となっている。このような冬場の路面凍結や路面への積雪を防止するために、凍結抑止や融雪、融氷のため、融雪剤が用いられている。 In cold regions with heavy snowfall, frozen roads and snow accumulation in winter are factors that cause traffic disruptions. To prevent roads from freezing and snow from accumulating on the road surface in winter, deicing agents are used to suppress freezing and melt snow and ice.
従来から用いられている融雪剤としては、例えば、塩化カルシウムや塩化ナトリウムが知られている。これら融雪剤は、融雪能力が高く、散布後直ちにその効果を発揮するため、固体状（粒状）または水溶液の状態で積雪した、あるいは凍結した路面等に散布され使用される（例えば、特許文献１）。 For example, calcium chloride and sodium chloride are known as snow-melting agents that have been used in the past. These snow-melting agents have a high snow-melting ability and are effective immediately after being spread, so they are spread in a solid (granular) or aqueous solution state on snow-covered or frozen road surfaces (for example, Patent Document 1).
しかしながら、塩化カルシウムや塩化ナトリウムは、融雪効果は速効性を有する反面、効果の持続時間が短く、融雪水が再凍結して路面に鏡面が発生するとかえって滑りやすくなり交通に支障を来たし、また地表に残存した塩化カルシウムが車両やフェンスなどの金属を錆びさせ、また土壌の残留や河川への流出によって環境汚染の原因となり、さらに植物の生長を阻害するなど動植物に対して安全衛生面での問題がある。 However, while calcium chloride and sodium chloride have a rapid snow-melting effect, the effect does not last long, and if the melted snow refreezes and creates a mirror-like surface on the road, it can make the road slippery and disrupt traffic. Furthermore, calcium chloride remaining on the ground surface can cause metal objects such as vehicles and fences to rust, and can cause environmental pollution if it remains in the soil or flows into rivers. It also poses health and safety problems for plants and animals, as it inhibits plant growth.
特許文献２には、融雪剤である金属塩にセルロースナノファイバーを含有させる融雪剤が記載されている。 Patent Document 2 describes a snow-melting agent in which cellulose nanofibers are contained in a metal salt that serves as the snow-melting agent.
しかしながら、上記特許文献１及び２に記載されたいずれの融雪剤も塩化カルシウムや塩化ナトリウムをはじめとする金属塩を使用したものであって、車両やフェンスなどの金属を錆びさせる塩害を発生させること、また土壌の残留や河川への流出による環境汚染を引き起こすという問題が生じる。 However, both of the snow-melting agents described in Patent Documents 1 and 2 use metal salts such as calcium chloride and sodium chloride, which can cause salt damage that can cause metals such as vehicles and fences to rust, and can also cause environmental pollution by leaving residues in the soil or running off into rivers.
また、路面の積雪や凍結のおそれが生じる度に、融雪剤を路面に散布する必要が生じるため、手間とコストを要していた。 In addition, whenever there was a risk of snow accumulation or freezing on the road surface, it was necessary to spread snow-melting agent on the road surface, which was time-consuming and costly.
本発明は、上記事情を鑑みてなされたものであり、本発明の融雪用塗料組成物を路面に塗布することにより、コンクリートやアスファルト等の路面に簡単に融雪効果を付与することができる。 The present invention was made in consideration of the above circumstances, and by applying the snow-melting paint composition of the present invention to road surfaces, it is possible to easily impart a snow-melting effect to road surfaces such as concrete and asphalt.

本発明に係る融雪用塗料組成物によれば、金属塩から成る融雪剤を使用せずに、又は、少ない使用量であっても、コンクリート又はアスファルト表面に存在している雪や氷を効率的に融解させることができる。また、コンクリート又はアスファルトの熱をコンクリート又はアスファルト表面に存在している雪や氷に効率的に伝えることができるため、積雪や凍結を防止することができる。 The snow-melting paint composition of the present invention can efficiently melt snow and ice on concrete or asphalt surfaces without using snow-melting agents made of metal salts, or even with only a small amount of use. In addition, the heat of the concrete or asphalt can be efficiently transferred to the snow and ice on the concrete or asphalt surface, preventing snow accumulation and freezing.
以下、本発明に係る融雪用塗料組成物の実施形態を詳細に説明する。しかし、本発明は以下の実施形態に限定されるものではない。 The following describes in detail the embodiments of the snow-melting paint composition according to the present invention. However, the present invention is not limited to the following embodiments.
＜＜融雪用塗料組成物＞＞
本発明に係る融雪用塗料組成物は、少なくとも、金属ケイ素の微粒子と、分散媒と、接着剤と、を含有することを特徴とする融雪用塗料組成物である。
<<Snow-melting paint composition>>
The snow-melting coating composition according to the present invention is characterized in that it contains at least fine particles of metallic silicon, a dispersion medium, and an adhesive.
本発明に係る融雪用塗料組成物における金属ケイ素の微粒子の濃度は、融雪用塗料組成物中に金属ケイ素の微粒子が均一に分散することができる濃度であれば特に制限されるものではないが、１ｇ／Ｌ以上３００ｇ／Ｌ以下の範囲が好ましく、１０ｇ／Ｌ以上１００ｇ／Ｌであることがより好ましく、１５ｇ／Ｌ以上５０ｇ／Ｌ以下であることがさらに好ましい。 The concentration of metal silicon particles in the snow-melting paint composition of the present invention is not particularly limited as long as the metal silicon particles can be uniformly dispersed in the snow-melting paint composition, but is preferably in the range of 1 g/L to 300 g/L, more preferably 10 g/L to 100 g/L, and even more preferably 15 g/L to 50 g/L.
分散媒及び接着剤の組成により最適な金属ケイ素微粒子の濃度は変化するものの、融雪用塗料組成物における金属ケイ素の微粒子の濃度が上記の範囲内であれば、分散媒に微粒子を均一に分散することが可能であり、塗料を塗布した際に均一厚みの塗膜を得ることができる。
微粒子濃度が上記範囲より高い場合には、粘度が高いことにより塗膜の形成が困難になる。微粒子濃度が上記範囲より低い場合には、融雪効果が著しく低下する。
Although the optimal concentration of metal silicon microparticles varies depending on the composition of the dispersion medium and adhesive, so long as the concentration of metal silicon microparticles in the snow-melting paint composition is within the above range, it is possible to uniformly disperse the microparticles in the dispersion medium, and a coating film of uniform thickness can be obtained when the paint is applied.
If the concentration of the fine particles is higher than the above range, the viscosity becomes high and it becomes difficult to form a coating film, whereas if the concentration of the fine particles is lower than the above range, the snow melting effect is significantly reduced.
本発明に係る融雪用塗料組成物は、その特性を損なわない範囲において、一般的に用いられる添加剤を含んでいてもよい。添加剤としては、例えば、分散剤、防腐剤、レベリング剤、防汚剤等が挙げられる。 The snow-melting paint composition of the present invention may contain commonly used additives as long as the additives do not impair the properties of the composition. Examples of additives include dispersants, preservatives, leveling agents, and antifouling agents.
＜金属ケイ素の微粒子＞
金属ケイ素の微粒子は、ケイ素を主成分として含む微粒子であれば良い。主成分とは、５０質量％以上を意味するものとする。本発明に係る金属ケイ素の微粒子は、単結晶であってもよく、多結晶であってもよく、非晶質であってもよい。
また、本発明に係る金属ケイ素の微粒子の体積平均粒子径は、０．１μｍ以上１００μｍ以下の範囲であることが好ましく、１μｍ以上１０μｍ以下の範囲であることがより好ましい。金属ケイ素の微粒子の形状は、特に限定されるものではなく、球形、フレーク形状、板状であってもよい。
<Metallic silicon particles>
The metal silicon particles may be particles containing silicon as a main component. The main component means 50% by mass or more. The metal silicon particles according to the present invention may be single crystal, polycrystalline, or amorphous.
The volume average particle size of the metal silicon particles according to the present invention is preferably in the range of 0.1 μm to 100 μm, more preferably in the range of 1 μm to 10 μm. The shape of the metal silicon particles is not particularly limited, and may be spherical, flake-shaped, or plate-shaped.
金属ケイ素は、他のセラミック材料に比べて熱伝導率が高く、熱交換効率を高くすることができるため、路面の熱を雪や氷に伝えやすく好ましい。さらに、金属ケイ素のモース硬度は７であり、硬度が高い上に酸化しにくいため、コンクリート又はアスファルトに塗布した場合であっても、劣化が生じにくい。 Silicon metal has a higher thermal conductivity than other ceramic materials, which allows it to increase heat exchange efficiency, making it preferable for transferring heat from the road surface to snow and ice. Furthermore, silicon metal has a Mohs hardness of 7, and because it is hard and resistant to oxidation, it is less likely to deteriorate even when applied to concrete or asphalt.
（テラヘルツ鉱石）
テラヘルツ鉱石は、金属ケイ素を主成分とする鉱石である。本発明に係るテラヘルツ鉱石は、純度９０％以上のケイ素から構成されていることが好ましく。より好ましくは純度９５％以上である。また、本発明に係るテラヘルツ鉱石の微粒子の体積平均粒子径は、０．１μｍ以上１００μｍ以下の範囲であることが好ましく、１μｍ以上１０μｍ以下の範囲であることがより好ましい。テラヘルツ鉱石の微粒子の形状は、特に限定されるものではなく、球形、フレーク形状、板状であってもよい。
(Terahertz ore)
The terahertz ore is an ore whose main component is metallic silicon. The terahertz ore according to the present invention is preferably composed of silicon with a purity of 90% or more. More preferably, the purity is 95% or more. The volume average particle size of the fine particles of the terahertz ore according to the present invention is preferably in the range of 0.1 μm to 100 μm, more preferably in the range of 1 μm to 10 μm. The shape of the fine particles of the terahertz ore is not particularly limited, and may be spherical, flake-shaped, or plate-shaped.
テラヘルツ鉱石は、外部から加熱等のエネルギーを加えることにより、テラヘルツ波を発生させると言われている鉱石である。テラヘルツ波は、周波数１００ＧＨｚ～１０ＴＨｚの電磁波であり、周波数が光波と電波との中間領域に該当する。ケイ素の純度が高いテラヘルツ鉱石を用いることにより、コンクリート又はアスファルトからの熱を受けた際に、テラヘルツ鉱石が効率的にテラヘルツ波を発生させることが期待でき、融雪効果を高めることができる。 Terahertz ore is said to generate terahertz waves when external energy such as heating is applied. Terahertz waves are electromagnetic waves with frequencies between 100 GHz and 10 THz, which is an intermediate frequency range between light waves and radio waves. By using terahertz ore with a high silicon purity, it is expected that the terahertz ore will efficiently generate terahertz waves when exposed to heat from concrete or asphalt, thereby enhancing the snow-melting effect.
本発明において体積平均粒子径は、水に金属ケイ素の微粒子又はテラヘルツ鉱石の微粒子を分散させて調製した分散液を光散乱法により測定することにより見積もることができる。体積平均粒子径は、前記微粒子の体積基準の粒度分布を光散乱法により測定し、得られた粒度分布（体積基準）において累積頻度が５０％となる粒子径（Ｄ５０）を採用することができる。 In the present invention, the volume average particle diameter can be estimated by measuring a dispersion liquid prepared by dispersing metal silicon particles or terahertz ore particles in water using a light scattering method. The volume average particle diameter can be determined by measuring the volume-based particle size distribution of the particles using a light scattering method, and using the particle diameter (D50) that has a cumulative frequency of 50% in the obtained particle size distribution (volume-based).
＜分散媒＞
分散媒は、金属ケイ素の微粒子を分散させ、接着剤に均一に分散させる役割を有する。本発明に係る融雪用塗料組成物中の分散媒の量は、金属ケイ素の微粒子の濃度が１ｇ／Ｌ以上３００ｇ／Ｌ以下の範囲内に収まるように調製できれば特に限定されるものではないが、例えば、本発明に係る融雪用塗料組成物の全体重量に対して、５重量％以上９５重量％以下の範囲とすることもできるし、５０重量％以上９０重量％以下の範囲とすることもできる。これら溶媒量は、塗布方法や外気温などにより使用者が適宜調整することが好ましい。
<Dispersion medium>
The dispersion medium plays a role of dispersing the metal silicon fine particles and dispersing them uniformly in the adhesive. The amount of the dispersion medium in the snow-melting coating composition according to the present invention is not particularly limited as long as it can be prepared so that the concentration of the metal silicon fine particles falls within the range of 1 g/L to 300 g/L, but for example, it can be in the range of 5 wt% to 95 wt%, or 50 wt% to 90 wt%, based on the total weight of the snow-melting coating composition according to the present invention. It is preferable that the user appropriately adjusts the amount of these solvents depending on the application method, outside temperature, etc.
分散媒は、分散媒の用途に応じて適宜選択することができ、金属ケイ素の微粒子と親和性の高いものであれば特に限定されるものではない。好適に用いることができる分散媒としては、例えば、水、メタノール、エタノール、１－プロパノール、２－プロパノール、１－ブタノール、２－ブタノール、オクタノール、グリセリン等のアルコール類や、酢酸エチル、酢酸ブチル、乳酸エチル、プロピレングリコールモノメチルエーテルアセテート、プロピレングリコールモノエチルエーテルアセテート、γ－ブチロラクトン等のエステル類や、ジエチルエーテル、エチレングリコールモノメチルエーテル（メチルセロソルブ）、エチレングリコールモノエチルエーテル（エチルセロソルブ）、エチレングリコールモノブチルエーテル（ブチルセロソルブ）、ジエチレングリコールモノメチルエーテル、ジエチレングリコールモノエチルエーテル等のエーテル類を好適に用いることができる。 The dispersion medium can be appropriately selected depending on the application of the dispersion medium, and is not particularly limited as long as it has a high affinity with the metal silicon particles. Examples of suitable dispersion media include alcohols such as water, methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, octanol, and glycerin, esters such as ethyl acetate, butyl acetate, ethyl lactate, propylene glycol monomethyl ether acetate, propylene glycol monoethyl ether acetate, and γ-butyrolactone, and ethers such as diethyl ether, ethylene glycol monomethyl ether (methyl cellosolve), ethylene glycol monoethyl ether (ethyl cellosolve), ethylene glycol monobutyl ether (butyl cellosolve), diethylene glycol monomethyl ether, and diethylene glycol monoethyl ether.
また、アセトン、メチルエチルケトン、メチルイソブチルケトン、アセチルアセトン、シクロヘキサノン等のケトン類や、ベンゼン、トルエン、キシレン、エチルベンゼン等の芳香族炭化水素や、シクロヘキサン等の環状炭化水素や、ジメチルホルムアミド、Ｎ，Ｎ－ジメチルアセトアセトアミド、Ｎ－メチルピロリドン等のアミド類や、ジメチルポリシロキサン、メチルフェニルポリシロキサン、ジフェニルポリシロキサン等の鎖状ポリシロキサン類を用いることもできる。 In addition, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, acetylacetone, and cyclohexanone, aromatic hydrocarbons such as benzene, toluene, xylene, and ethylbenzene, cyclic hydrocarbons such as cyclohexane, amides such as dimethylformamide, N,N-dimethylacetoacetamide, and N-methylpyrrolidone, and chain polysiloxanes such as dimethylpolysiloxane, methylphenylpolysiloxane, and diphenylpolysiloxane can also be used.
また、オクタメチルシクロテトラシロキサン、デカメチルシクロペンタシロキサン、ドデカメチルシクロヘキサンシロキサン等の環状ポリシロキサン類や、アミノ変性ポリシロキサン、ポリエーテル変性ポリシロキサン、アルキル変性ポリシロキサン、フッ素変性ポリシロキサン等の変性ポリシロキサン類を用いることもできる。 Cyclic polysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexanesiloxane, and modified polysiloxanes such as amino-modified polysiloxane, polyether-modified polysiloxane, alkyl-modified polysiloxane, and fluorine-modified polysiloxane can also be used.

以上述べた様々な種類の分散媒は、必要に応じて１種のみを単独で用いてもよく、２種以上を混合して用いてもよい。
In addition, hydrophobic dispersion media such as hydrocarbon oils such as liquid paraffin, squalane, isoparaffin, branched light paraffin, Vaseline, ceresin, naphtha, gasoline, kerosene, light oil, heavy oil, and petroleum-based heavy oil; ester oils such as isopropyl myristate, cetyl isooctanoate, and glyceryl trioctanoate; silicone oils such as decamethylcyclopentasiloxane, dimethylpolysiloxane, and methylphenylpolysiloxane; higher fatty acids such as uric acid, myristic acid, palmitic acid, and stearic acid; and higher alcohols such as lauryl alcohol, cetyl alcohol, stearyl alcohol, hexyldodecanol, and isostearyl alcohol may be used.
Of the various types of dispersion media described above, one type may be used alone, or two or more types may be mixed and used as needed.
分散媒として水性溶媒又は水を用いる場合には、分散媒中に塩酸、硫酸、硝酸、脂肪酸を添加し、本発明に係る融雪用塗料組成物のｐＨを適宜調整することができる。本発明に係る融雪用塗料組成物のｐＨは、１以上６以下であることが好ましく、金属ケイ素の微粒子と接着剤との親和性、分散性を向上させる点で３以上５以下であることがより好ましい。 When an aqueous solvent or water is used as the dispersion medium, hydrochloric acid, sulfuric acid, nitric acid, or a fatty acid can be added to the dispersion medium to appropriately adjust the pH of the snow-melting paint composition of the present invention. The pH of the snow-melting paint composition of the present invention is preferably 1 or more and 6 or less, and more preferably 3 or more and 5 or less in terms of improving the affinity and dispersibility between the metal silicon fine particles and the adhesive.
分散媒は、その特性を損なわない範囲において、一般的に用いられる添加剤を含んでいてもよい。添加剤としては、例えば、分散剤、安定剤、水溶性バインダー、界面活性剤、増粘剤、油溶性防腐剤、紫外線吸収剤、油溶性薬剤、油溶性色素類、油溶性蛋白質類、鉱物油、植物油、動物油等が挙げられる。 The dispersion medium may contain commonly used additives as long as the properties of the dispersion medium are not impaired. Examples of additives include dispersants, stabilizers, water-soluble binders, surfactants, thickeners, oil-soluble preservatives, UV absorbers, oil-soluble drugs, oil-soluble dyes, oil-soluble proteins, mineral oils, vegetable oils, and animal oils.
＜接着剤＞
接着剤は、金属ケイ素の微粒子を基材であるコンクリート又はアスファルト表面に固定する役割を有する。接着剤は、金属ケイ素と親和性が高く、かつ、コンクリート又はアスファルト表面と接着することができる物であれば特に限定されるものではなく、公知公用の物を用いることができる。例えば、エポキシ樹脂、アクリル樹脂、メタクリル樹脂、ポリウレア樹脂、ウレタン樹脂などを接着剤として使用してもよく、舗装用石油アスファルトであるストレートアスファルト、改質アスファルトを接着剤として使用してもよい。改質アスファルトとしては、ブローンアスファルト；熱可塑性エラストマー、熱可塑性樹脂等のポリマー（高分子材料）で改質したアスファルト等が挙げられる。
<Adhesive>
The adhesive has a role of fixing the metal silicon fine particles to the concrete or asphalt surface as the substrate. The adhesive is not particularly limited as long as it has a high affinity with metal silicon and can adhere to the concrete or asphalt surface, and any publicly known adhesive can be used. For example, epoxy resin, acrylic resin, methacrylic resin, polyurea resin, urethane resin, etc. may be used as the adhesive, and straight asphalt, which is petroleum asphalt for paving, or modified asphalt may be used as the adhesive. Examples of modified asphalt include blown asphalt; asphalt modified with polymers (polymer materials) such as thermoplastic elastomers and thermoplastic resins, etc.
金属ケイ素の微粒子をアスファルト表面に固定する場合には、中でもストレートアスファルトを接着剤として用いることが好ましい。ストレートアスファルトは、金属ケイ素の微粒子を均一に分散させることができることに加え、アスファルトと親和性が高く、金属ケイ素の微粒子をアスファルト表面に強固に固定することができる。ストレートアスファルトを接着剤として用いる場合には、塗布方法や外気温に応じて重質油をさらに添加して用いることもできる。 When fixing metal silicon particles to an asphalt surface, it is preferable to use straight asphalt as an adhesive. Straight asphalt can disperse metal silicon particles uniformly, and has a high affinity with asphalt, allowing the metal silicon particles to be firmly fixed to the asphalt surface. When using straight asphalt as an adhesive, heavy oil can also be added depending on the application method and outside temperature.
ストレートアスファルトとは、原油を常圧蒸留装置、減圧蒸留装置等にかけて得られる残留瀝青物質のことである。また、ブローンアスファルトとは、ストレートアスファルトと重質油との混合物を加熱し、その後空気を吹き込んで酸化させることによって得られるアスファルトを意味する。 Straight asphalt is the residual bitumen material obtained by subjecting crude oil to atmospheric distillation equipment, vacuum distillation equipment, etc. Blown asphalt is asphalt obtained by heating a mixture of straight asphalt and heavy oil, then blowing air into it to oxidize it.
接着剤を塗布する工程の前に、コンクリート又はアスファルトの上面を研磨又は清掃する工程を備えていることが好ましい。金属ケイ素と、コンクリート又はアスファルトとの密着性をより一層強固にすることができる。 It is preferable to have a step of polishing or cleaning the top surface of the concrete or asphalt before the step of applying the adhesive. This can further strengthen the adhesion between the silicon metal and the concrete or asphalt.
接着剤は、金属ケイ素の微粒子の濃度が１ｇ／Ｌ以上３００ｇ／Ｌ以下の範囲内に収まるように調製できれば特に限定されるものではないが、例えば、本発明に係る融雪用塗料組成物の全体重量に対して、１重量％以上５０重量％以下の範囲とすることが好ましく、５重量％以上２０重量％以下の範囲とすることがより好ましい。接着剤の量が多い場合には、コンクリート又はアスファルト表面に融雪用塗料組成物を塗布する際に伸びが悪く均一な膜厚で塗布することが難しくなる。接着剤の量が少ない場合には、金属ケイ素と、コンクリート又はアスファルトとの密着性を確保することができない懸念がある。 The adhesive is not particularly limited as long as it can be prepared so that the concentration of metal silicon particles is within the range of 1 g/L to 300 g/L. For example, the range of 1 wt % to 50 wt % and more preferably 5 wt % to 20 wt % of the total weight of the snow-melting paint composition of the present invention is preferable. If the amount of adhesive is too large, the snow-melting paint composition will not spread well when applied to the concrete or asphalt surface, making it difficult to apply with a uniform film thickness. If the amount of adhesive is too small, there is a concern that the adhesion between the metal silicon and the concrete or asphalt may not be ensured.
＜＜融雪用塗料組成物の作製＞＞
本発明に係る融雪用塗料組成物の製造方法は、特に限定されないが、例えば、分散媒に金属ケイ素の微粒子を加え、金属ケイ素分散液を作製した後、接着剤を加えて、再度よく攪拌することで製造することができる。
前記の攪拌の方法は、特に限定されるものではなく、公知の混合装置で機械的に混合する方法を用いることができる。例えば、撹拌機、自公転式ミキサー、ホモミキサー、超音波ホモジナイザー等を用いることができる。
<<Preparation of snow-melting paint composition>>
The method for producing the snow-melting paint composition of the present invention is not particularly limited, but it can be produced, for example, by adding fine particles of metallic silicon to a dispersion medium to prepare a metallic silicon dispersion, adding an adhesive, and stirring thoroughly again.
The stirring method is not particularly limited, and a method of mechanically mixing using a known mixing device can be used, such as a stirrer, a planetary mixer, a homomixer, or an ultrasonic homogenizer.
＜＜融雪用塗料の塗膜形成＞＞
本発明に係る融雪用塗料組成物をコンクリート又はアスファルトの表面に塗布し、塗膜を形成させる方法としては、公知公用の方法を採用することができる。例えばロールコート法、フローコート法、スプレーコート法、刷毛塗り法等の通常の塗布方法により、塗膜を形成することができる。
<<Formation of coating film for snow-melting paint>>
The method for applying the snow-melting coating composition according to the present invention to the surface of concrete or asphalt to form a coating film can be any known method. For example, the coating film can be formed by a conventional coating method such as roll coating, flow coating, spray coating, or brush coating.
融雪用塗料の塗膜の膜厚に関しは、特に限定されるものではないが、例えば、乾燥後の膜厚が５μｍ以上３ｍｍ以下の範囲とすることが好ましく、１００μｍ以上１ｍｍ以下の範囲とすることがさらに好ましい。 There are no particular limitations on the thickness of the coating of the snow-melting paint, but for example, it is preferable that the thickness of the coating after drying be in the range of 5 μm to 3 mm, and more preferably in the range of 100 μm to 1 mm.
以下の実施例及び比較例において、「部」及び「％」は特記しない限り「質量部」及び「質量％」である。 In the following examples and comparative examples, "parts" and "%" are "parts by mass" and "% by mass" unless otherwise specified.
＜アスファルト基材の作製＞
本実施例において、融雪用塗料組成物の融雪効果を検証するための基材として、アスファルト材を使用した。アスファルト材は、砂利等の骨材と加熱アスファルトとを混錬することにより作製した。混錬した骨材入りの高温のアスファルト混合物を直径３０ｃｍ、高さ１０ｃｍの金属製の容器に敷き詰めた。その後、アスファルト混合物を約８０ｋｇの重さで踏み固めた後に放冷し、厚さ５ｃｍ程度のアスファルト基材を作製した。
<Preparation of asphalt base material>
In this example, an asphalt material was used as a substrate to verify the snow-melting effect of the snow-melting coating composition. The asphalt material was prepared by mixing aggregate such as gravel with heated asphalt. The mixed aggregate-containing hot asphalt mixture was spread in a metal container with a diameter of 30 cm and a height of 10 cm. The asphalt mixture was then compacted with a weight of about 80 kg and allowed to cool, producing an asphalt substrate with a thickness of about 5 cm.
＜融雪用塗料組成物の融雪効果の検証＞

[Comparative Example 3]
100 g of terahertz ore particles with a volume average particle size of 5 um was added to 300 mL of distilled water and stirred for 10 minutes to prepare a terahertz ore dispersion. 100 mL of adhesive consisting of 50 wt% straight asphalt, 45 wt% distilled water, 3 wt% A heavy oil, additives, etc. was added to the obtained terahertz ore dispersion and stirred for 10 minutes. Furthermore, hydrochloric acid was added to adjust the pH to 4, and a coating composition of Comparative Example 3 was prepared.
A coating film of the coating composition of Comparative Example 3 was formed on the surface of an asphalt substrate in the same manner as described in Example 1, and then the snow-melting effect of the coating composition of Comparative Example 3 was verified in the same manner as described in Example 1. The results are shown in Table 1.
表１の結果より、テラヘルツ鉱石を１０ｇ以上２０ｇ以下の範囲で含む融雪用塗料組成物の塗膜を形成したアスファルト材では、アスファルト表面の氷を融解するのに要した時間が１５分であった（実施例１及び２）。テラヘルツ鉱石を用いていない塗料組成物の塗膜を形成したアスファルト材の場合には、アスファルト表面の氷を融解するのに要した時間が１７．５分であったことから、テラヘルツ鉱石がアスファルト表面に存在している氷又は雪の融解を促進する効果を有していることが分かる（比較例１）。これは、金属ケイ素から成るテラヘルツ鉱石の熱伝導率がアスファルト材よりも高いために地熱を効率的に氷や雪に伝えることができるためであると考えられる。 From the results in Table 1, it took 15 minutes to melt the ice on the asphalt surface when an asphalt material was coated with a coating of a snow-melting paint composition containing 10 g to 20 g of terahertz ore (Examples 1 and 2). In the case of an asphalt material coated with a coating of a paint composition that did not use terahertz ore, it took 17.5 minutes to melt the ice on the asphalt surface, which shows that terahertz ore has the effect of promoting the melting of ice or snow present on the asphalt surface (Comparative Example 1). This is thought to be because the thermal conductivity of terahertz ore, which is made of metallic silicon, is higher than that of the asphalt material, and therefore geothermal heat can be efficiently transferred to ice and snow.
テラヘルツ鉱石を３０ｇ含む融雪用塗料組成物の塗膜を形成したアスファルト材では、アスファルト表面の氷を融解するのに要した時間が１５．５分であった（実施例３）。テラヘルツ鉱石を４０ｇ又は５０ｇ含む融雪用塗料組成物の塗膜を形成したアスファルト材では、アスファルト表面の氷を融解するのに要した時間が１６分であった（実施例４又は５）。 When an asphalt material was coated with a coating of a snow-melting paint composition containing 30 g of terahertz ore, it took 15.5 minutes to melt the ice on the asphalt surface (Example 3).When an asphalt material was coated with a coating of a snow-melting paint composition containing 40 g or 50 g of terahertz ore, it took 16 minutes to melt the ice on the asphalt surface (Examples 4 and 5).
テラヘルツ鉱石を５ｇ含む融雪用塗料組成物の塗膜を形成したアスファルト材では、アスファルト表面の氷を融解するのに要した時間が１７分であった（比較例２）。この結果から、テラヘルツ鉱石が５ｇ以下の融雪用塗料組成物を用いた場合には、融雪効果を得ることはできなかった。一方、テラヘルツ鉱石を１００ｇ含む融雪用塗料組成物の塗膜を形成したアスファルト材では、融雪用塗料組成物の粘度が高くなり、アスファルト表面に均一な塗膜を形成することができなかった（比較例３）。 When an asphalt material was coated with a coating of a snow-melting paint composition containing 5 g of terahertz ore, it took 17 minutes to melt the ice on the asphalt surface (Comparative Example 2). From these results, it was not possible to obtain a snow-melting effect when a snow-melting paint composition containing 5 g or less of terahertz ore was used. On the other hand, when an asphalt material was coated with a coating of a snow-melting paint composition containing 100 g of terahertz ore, the viscosity of the snow-melting paint composition increased, and it was not possible to form a uniform coating on the asphalt surface (Comparative Example 3).
