Description

本発明はシリコーン塗料組成物とその製造方法に関する。   The present invention relates to a silicone coating composition and a method for producing the same.

シリコーンを用いた塗料は、シロキサン結合を主鎖とすることから、一般に耐熱性、耐候性、撥水性、電気絶縁性に優れ、また屈曲性や柔軟性、更には透明性にも優れることから、広く使用されている。
シリコーンにアルコキシ基を導入することで、アルコキシ基の加水分解によりシラノールが生成され、更に縮合反応による脱水が行われて硬化、固体化させることができる。従って、このような材料を塗料として部材の表面に塗布することで、硬化し、安定した塗装薄膜を得ることが可能となる。
しかしながら、アルコキシ基を有するオルガノシロキサンの前記加水分解、縮合による硬化を、自然条件だけにたよる場合には長時間を有し、塗料としての性能を充分に果たすことができない。
このため、従来よりオルガノシロキサンの加水分解、縮合反応による硬化を促進させる試みが種々なされている。
またこれらのシリコーン塗料に銀等の抗菌成分を含有させたものも提供されている。
Since the coating using silicone has a siloxane bond as the main chain, it is generally excellent in heat resistance, weather resistance, water repellency, electrical insulation, flexibility, flexibility, and transparency. Widely used.
By introducing an alkoxy group into silicone, silanol is generated by hydrolysis of the alkoxy group, and further dehydration can be performed by condensation reaction to be cured and solidified. Therefore, by applying such a material as a paint to the surface of the member, it is possible to obtain a cured coating film that is cured and stable.
However, when the curing by hydrolysis and condensation of the organosiloxane having an alkoxy group depends only on natural conditions, the organosiloxane has a long time and cannot sufficiently perform the performance as a paint.
For this reason, various attempts have been made to accelerate curing by hydrolysis and condensation reactions of organosiloxanes.
In addition, those silicone paints containing an antibacterial component such as silver are also provided.

先ず、本発明のシリコーン塗料組成物に係る実施形態を説明する。
本発明の実施形態に係るシリコーン塗料組成物は、加水分解性オルガノポリシロキサンに酢酸銀を触媒として且つ抗菌成分として添加したものである。
First, an embodiment according to the silicone coating composition of the present invention will be described.
The silicone coating composition according to the embodiment of the present invention is obtained by adding silver acetate as a catalyst and an antibacterial component to hydrolyzable organopolysiloxane.

前記加水分解性オルガノポリシロキサンは、主鎖にSi−Oのシロキサン結合構造を持ち、側鎖にメチル基を持つシリコーンオリゴマーとフェニル基を持つシリコーンオリゴマーとから基本液を作る。メチル基だけのシリコーンオリゴマーの選択もあるが、メチル基だけでは得られる塗膜の硬度が上がりすぎる。塗膜の硬度調整剤としてフェニル基のシリコーンオリゴマーを混合する。   The hydrolyzable organopolysiloxane forms a basic solution from a silicone oligomer having a Si—O siloxane bond structure in the main chain and having a methyl group in the side chain and a silicone oligomer having a phenyl group. Although there is a selection of a silicone oligomer having only a methyl group, the hardness of the obtained coating film is excessively increased only by the methyl group. A phenyl group silicone oligomer is mixed as a hardness adjusting agent for the coating film.

前記加水分解性オルガノポリシロキサンの製造は、メチル系シリコーンオリゴマー165部にフェニル系シリコーンオリゴマー120部を加え、更にメチルトリメトキシシラン15部を加え、60℃で90分攪拌して行う。これによって分子の両端がアルコキシ官能基Rで封鎖された3次元構造の加水分解性オルガノポリシロキサンが得られる。
なお前記メチル系シリコーンオリゴマーとフェニル系シリコーンオリゴマーとの比率は、165部対120部に限定されない。塗膜の硬度を硬くする場合にはメチル系シリコーンオリゴマーの量を多くし、塗膜の硬度を柔らかくする場合には、その程度に応じてフェニル系シリコーンオリゴマーの量を多くしてゆく。またメチルトリメトキシシランの量も必ずしも15部である必要はない。加水分解性オルガノポリシロキサンの側鎖にアルコキシ基をどの程度の割合で導入するかによって、適当な割合が選択される。ただし、メチルトリメトキシシランの量は5部〜30部とする。5部未満であれば、後述する触媒を加えても実質上、加水分解反応が生じない。また30部を超えると、やはり加水分解反応がうまく進まない。好ましくは12部〜18部とする。
得られた加水分解性オルガノポリシロキサンの化学構造式を化学式1に示す。
The hydrolyzable organopolysiloxane is produced by adding 120 parts of phenyl silicone oligomer to 165 parts of methyl silicone oligomer, further adding 15 parts of methyltrimethoxysilane, and stirring at 60 ° C. for 90 minutes. As a result, a hydrolyzable organopolysiloxane having a three-dimensional structure in which both ends of the molecule are blocked with an alkoxy functional group R 1 is obtained.
The ratio of the methyl silicone oligomer to the phenyl silicone oligomer is not limited to 165 parts to 120 parts. When the hardness of the coating film is increased, the amount of the methyl silicone oligomer is increased. When the hardness of the coating film is decreased, the amount of the phenyl silicone oligomer is increased according to the degree. Also, the amount of methyltrimethoxysilane is not necessarily 15 parts. An appropriate ratio is selected depending on the ratio of the alkoxy group introduced into the side chain of the hydrolyzable organopolysiloxane. However, the amount of methyltrimethoxysilane is 5 to 30 parts. If it is less than 5 parts, even if it adds the catalyst mentioned later, a hydrolysis reaction does not arise substantially. If it exceeds 30 parts, the hydrolysis reaction does not proceed well. The amount is preferably 12 to 18 parts.
The chemical structural formula of the resulting hydrolyzable organopolysiloxane is shown in Chemical Formula 1.

Figure 2009035621
Figure 2009035621

化学式1において、RとRはフェニル基またはメチル基によって選ばれた同一基または異なる基を示し、Rはメチル基またはフェニル基、或いは炭素数1〜5のアルコキシ基より選ばれる同一または異なる基を示し、n個のRは最低1個のアルコキシ基を示す。nは2〜10の数を示す。 In Chemical Formula 1, R 1 and R 2 represent the same group selected by a phenyl group or a methyl group or different groups, and R 3 is the same or selected from a methyl group, a phenyl group, or an alkoxy group having 1 to 5 carbon atoms. N represents different groups, n R 3 represents at least one alkoxy group. n shows the number of 2-10.

得られた加水分解性オルガノポリシロキサンは有効成分が100%であり、水分がなければ安定して存在する。しかしアルコキシシラン基が付加されたことで、このオルガノポリシロキサンは、常温下で空気に触れると空気中の湿気と反応し、アルコキシシラン基(Si−OR)が加水分解され、シラノール基(Si−OH)が生成される。そして更に、このシラノール基の脱水反応によって硬化される。この硬化速度はアルコキシ基の加水分解反応速度と比例する。加水分解から脱水反応を経て、結果として透明な薄いシロキサン結合の膜が形成される。この薄膜は、塗布であれば1〜40ミクロン程度まで厚みを調整することができる。
得られる塗膜は光沢性に富み、透明性は90%を超える。また硬度は鉛筆硬度で3Hまで上がり、シリコーンの構造上において珪素と酸素の結合エネルギーが1モル当たり106キロカロリーと大きいために酸性雨にも耐えうる性質を持つ。
The obtained hydrolyzable organopolysiloxane has 100% active ingredient and exists stably without water. However, when an alkoxysilane group is added, this organopolysiloxane reacts with moisture in the air when exposed to air at room temperature, and the alkoxysilane group (Si-OR) is hydrolyzed to produce a silanol group (Si--). OH) is produced. Further, it is cured by a dehydration reaction of this silanol group. This curing rate is proportional to the hydrolysis reaction rate of the alkoxy group. Through hydrolysis and dehydration, a transparent thin siloxane-bonded film is formed as a result. If this thin film is applied, the thickness can be adjusted to about 1 to 40 microns.
The resulting coating film is rich in gloss and has a transparency of over 90%. Further, the hardness increases to 3H in pencil hardness, and since it has a large bond energy between silicon and oxygen of 106 kilocalories per mole on the silicone structure, it has the property to withstand acid rain.

ただし前記の加水分解性オルガノポリシロキサンは、そのままの自然条件下であれば、含有するアルコキシ基の加水分解の速度はかなり遅く、脱水硬化に長時間を要する。
このため本発明では、前記加水分解性オルガノポリシロキサンの加水分解反応を促進させるため、研究と実験を繰り返した結果、酢酸銀(AgCHCOOH)を触媒として加えるのが最適であることを見出した。
そして酢酸銀として銀イオンを導入することで、触媒作用の他に抗菌作用も同時的に発揮させることができることを見出した。
However, the hydrolyzable organopolysiloxane has a considerably slow hydrolysis rate of the contained alkoxy group under natural conditions as it is, and requires a long time for dehydration and curing.
For this reason, in this invention, in order to accelerate the hydrolysis reaction of the hydrolyzable organopolysiloxane, as a result of repeating research and experiment, it was found that it is optimal to add silver acetate (AgCH 3 COOH) as a catalyst. .
It was also found that by introducing silver ions as silver acetate, an antibacterial action can be exhibited simultaneously with the catalytic action.

酢酸銀の添加量は、1〜15重量%とする。1重量%未満の場合には、触媒としての効果が薄く、また銀による抗菌効果も薄い。一方、15重量%を超えると、塗膜の性質が劣化し、機械的強度が低下すると共に、透明性等も悪くなる。
酢酸銀の添加量は、触媒としては一般的に多くを必要としない。一方、抗菌作用をもたらす酢酸銀の添加量としては、多いのに越したことはない。しかし、酢酸銀の量が多すぎると塗膜の性質が劣化する。
酢酸銀の添加量は、より好ましくは、1.5〜2重量%とするのがよい。
The amount of silver acetate added is 1 to 15% by weight. When the amount is less than 1% by weight, the effect as a catalyst is low, and the antibacterial effect due to silver is also low. On the other hand, when it exceeds 15% by weight, the properties of the coating film deteriorate, the mechanical strength decreases, and the transparency and the like also deteriorate.
The amount of silver acetate added generally does not require much as a catalyst. On the other hand, the addition amount of silver acetate that brings about an antibacterial action is never too much. However, if the amount of silver acetate is too large, the properties of the coating film deteriorate.
The amount of silver acetate added is more preferably 1.5 to 2% by weight.

酢酸銀は、その粉末をアルコール系溶媒に入れて溶かす。そしてこの酢酸銀を溶かしたアルコール系液を加水分解性オルガノポリシロキサンに加え、攪拌することで、酢酸銀を加水分解性オルガノポリシロキサンに均一に分散させる。
前記アルコール系溶媒は、典型的にはアルコールそのものであり、鎖式または脂環式の炭化水素の水素原子を水酸基で置換したヒドロキシ化合物である。しかし、それ以外に、水酸基以外に官能基を持つアルコール誘導体、エステルを含むものとする。具体的には低級アルコールが扱いやすく、危険性も少ないので好ましい。
Silver acetate is dissolved in an alcohol solvent. Then, the alcoholic solution in which the silver acetate is dissolved is added to the hydrolyzable organopolysiloxane and stirred to uniformly disperse the silver acetate in the hydrolyzable organopolysiloxane.
The alcohol solvent is typically an alcohol itself, and is a hydroxy compound in which a hydrogen atom of a chain or alicyclic hydrocarbon is substituted with a hydroxyl group. However, in addition, alcohol derivatives and esters having functional groups other than hydroxyl groups are included. Specifically, lower alcohols are preferable because they are easy to handle and less dangerous.

前記酢酸銀を添加した加水分解性オルガノポリシロキサンを攪拌することで、触媒作用が開始される。
酢酸基の存在により、アルコキシ基の加水分解が大幅に促進され、脱水反応も速まる。その結果、硬化時間は大幅に短縮され、80〜100℃の加熱下で、およそ30分〜60分程度で薄膜の表面が硬化する。硬化すれば、水中のような過酷な条件のところで使用しても亀裂、剥離などが生じず、耐久性、耐候性が高い。
前記酢酸銀を添加し、攪拌した塗料組成物は素早くエアーガンのカップに投入し、できるだけ短時間で対象物に塗布する。対象物の種類は金属、樹脂、その他、種類を問わない。
塗布直後に、表面にシロキサン結合の透明な光沢性のある薄膜を形成することができる。酢酸基の触媒でシロキサン結合が弱められることもなく、抗菌性のある、無溶剤型で、一液性、常温湿気硬化するシロキサン結合薄膜が短時間で形成される。薄膜は7日程度で鉛筆硬度3Hまで硬化し、曲げに対する追従性もある。
Catalysis is initiated by stirring the hydrolyzable organopolysiloxane to which the silver acetate has been added.
The presence of the acetic acid group greatly accelerates the hydrolysis of the alkoxy group and accelerates the dehydration reaction. As a result, the curing time is greatly shortened, and the surface of the thin film is cured in about 30 to 60 minutes under heating at 80 to 100 ° C. If it is cured, it will not crack or peel even when used under severe conditions such as underwater, and has high durability and weather resistance.
The silver acetate is added and the stirred coating composition is quickly put into an air gun cup and applied to the object in as short a time as possible. The type of the object is not limited to metal, resin, or any other type.
Immediately after application, a transparent glossy thin film having a siloxane bond can be formed on the surface. A siloxane bond thin film that is antibacterial, solvent-free, one-component, and room temperature moisture-curing is formed in a short time without siloxane bond weakening with an acetic acid group catalyst. The thin film is cured to a pencil hardness of 3H in about 7 days, and has a followability to bending.

特筆すべきことは、酢酸銀を添加することで、上記触媒の作用効果の他に、同時に塗料組成物に抗菌性と消臭性をも付与させることができることである。そしてその2つの機能を塗料組成物にもたらすのに、複数工程を必要とすることなく、酢酸銀を添加するという一工程で全て達成できるということである。   What should be noted is that, by adding silver acetate, in addition to the action and effect of the catalyst, at the same time, antibacterial and deodorant properties can be imparted to the coating composition. And, in order to bring the two functions to the coating composition, it is possible to achieve all in one step of adding silver acetate without requiring a plurality of steps.

酢酸銀を加水分解性オルガノポリシロキサンに添加、攪拌することにより、銀イオンが常温硬化した薄膜の表面に分散した状態となり、抗菌作用、消臭作用を発揮する。
銀を直接的に添加するのではなく、酢酸銀として添加するので、銀単体そのものを原料として購入、管理する必要もないし、微粉末に加工したり、銀の分散液を調整する必要もない。よってまた製造工程も短縮でき、製造コストの低減も図れる。
When silver acetate is added to the hydrolyzable organopolysiloxane and stirred, the silver ions are dispersed on the surface of the thin film that has been cured at room temperature, and exhibit antibacterial and deodorizing effects.
Since silver is not added directly but as silver acetate, it is not necessary to purchase and manage the silver itself as a raw material, nor to process it into a fine powder or to adjust the silver dispersion. Therefore, the manufacturing process can be shortened and the manufacturing cost can be reduced.

薄膜は1〜40ミクロン程度までの厚みを調整することができる。また一度塗布したあとから再度上塗りして厚みを調整することもできる。
塗膜は抗菌性、耐候性、耐水性、耐熱性、耐薬品性、耐衝撃性、屈曲性、透明性に優れる。
The thin film can be adjusted to a thickness of about 1 to 40 microns. It is also possible to adjust the thickness by recoating once applied.
The coating film is excellent in antibacterial properties, weather resistance, water resistance, heat resistance, chemical resistance, impact resistance, flexibility, and transparency.
