Description

水性聚氨酯分散體及含彼的組合物Aqueous polyurethane dispersion and composition containing it

本發明是關於一種水性聚氨酯分散體(aqueous polyurethane dispersion,PUD);特定而言,本發明是關於一種陽離子型水性聚氨酯分散體(cationic aqueous polyurethane dispersion,CAPUD)。該水性聚氨酯分散體尤其有利於改良聚氨酯發泡體、真皮、合成皮或織物的機械性質。The present invention relates to an aqueous polyurethane dispersion (aqueous polyurethane dispersion, PUD); specifically, the present invention relates to a cationic aqueous polyurethane dispersion (cationic aqueous polyurethane dispersion, CAPUD). The aqueous polyurethane dispersions are especially advantageous for improving the mechanical properties of polyurethane foams, genuine leather, synthetic leather or textiles.

聚氨酯因其軟硬度可調範圍廣、耐低溫、柔韌性好、附著力強等優點被廣泛應用於皮革塗飾劑、木器漆、塗料、黏著劑、塑件、鋼鐵、紡織、製鞋、紙張等領域。已知一般溶劑型聚氨酯使用大量有機溶劑,其衍生的揮發性有機物(VOC)對環境及人體造成不良影響。隨著世界各國環保法規日趨嚴厲,近年對於水性聚氨酯的需求及性質要求漸增。Polyurethane is widely used in leather finishing agents, wood lacquers, coatings, adhesives, plastic parts, steel, textiles, shoemaking, and paper because of its wide range of softness and hardness, low temperature resistance, good flexibility, and strong adhesion. and other fields. It is known that general solvent-based polyurethanes use a large amount of organic solvents, and the volatile organic compounds (VOCs) derived from them have adverse effects on the environment and human body. With the increasingly stringent environmental protection regulations around the world, the demand and property requirements for water-based polyurethane have been increasing in recent years.

在水性聚氨酯的製備過程中,為獲得穩定分散的聚氨酯乳液,一般需在聚氨酯寡聚物(預聚物)的分子中引入親水基團,使其在水中乳化。根據所引入基團的帶電性,水性聚氨酯可區分為陽離子型水性聚氨酯(CAPUD)、陰離子型水性聚氨酯、非離子型水性聚氨酯、以及混合型水性聚氨酯。In the preparation process of waterborne polyurethane, in order to obtain a stable and dispersed polyurethane emulsion, it is generally necessary to introduce hydrophilic groups into the molecules of polyurethane oligomers (prepolymers) to emulsify them in water. According to the chargeability of the introduced groups, waterborne polyurethane can be divided into cationic waterborne polyurethane (CAPUD), anionic waterborne polyurethane, nonionic waterborne polyurethane, and mixed waterborne polyurethane.

一般常見的水性聚氨酯分散體多屬陰離子型的水性聚氨酯分散體。對於陽離子型水性聚氨酯(CAPUD)而言,由於聚氨酯本身具有胺基甲酸酯結構,再加上形成CAPUD所需的季銨鹽離子中心,使得CAPUD易黃變且在高溫下黃變情況更加嚴重,故CAPUD的商品化過程仍存在相當困難。Generally, the common water-based polyurethane dispersions are mostly anionic water-based polyurethane dispersions. For cationic waterborne polyurethane (CAPUD), because polyurethane itself has a urethane structure, coupled with the quaternary ammonium salt ion center required to form CAPUD, CAPUD is prone to yellowing and the yellowing is more serious at high temperatures , so the commercialization process of CAPUD is still quite difficult.

水性聚氨酯分散體若在塗料中作為色漆應用,一般需於色漆上施作保護性清漆,惟清漆通常含有有機溶劑,若基於水性聚氨酯分散體的色漆塗膜的耐溶劑性不佳,則清漆所含的有機溶劑即會侵蝕塗膜表面,導致最終外觀失光或色相不均勻等問題。If the water-based polyurethane dispersion is used as a paint in paint, it is generally necessary to apply a protective varnish on the paint, but the varnish usually contains organic solvents. If the solvent resistance of the paint film based on water-based polyurethane dispersion is not good, The organic solvent contained in the varnish will erode the surface of the coating film, resulting in problems such as loss of gloss or uneven hue in the final appearance.

水性聚氨酯分散體若作為表面處理劑,或是在塗料中作為最外層的面漆應用,在終端產品應用會遇到溶劑(例如酒精)清洗或擦拭的情形,對於耐溶劑性要求更加嚴苛。If the water-based polyurethane dispersion is used as a surface treatment agent or as the outermost topcoat in the coating, it will encounter solvent (such as alcohol) cleaning or wiping in the end product application, and the requirements for solvent resistance are more stringent.

因此,所屬技術領域中亟需一種具有製備方法簡單、改善前述缺點(如:改良在高溫下的耐黃變性(下稱「耐熱黃變性」)及/或耐溶劑性的新穎CAPUD。Therefore, there is an urgent need in the technical field for a novel CAPUD that has a simple preparation method, improves the aforementioned shortcomings (eg, improves yellowing resistance at high temperature (hereinafter referred to as "heat yellowing resistance") and/or solvent resistance.

Therefore, the polyol with tertiary amino groups not only acts as a chain extender but also improves the hydrophilicity of polyurethane oligomers. The degree of improvement has a significant effect. The inventors of this case found that if the dispersibility of polyurethane in water is not good, it is easy to cause CAPUD to present a milky white appearance, or even delamination.

表3中,各性質的量測方式如下。In Table 3, the measurement methods of each property are as follows.

固含量的量測:首先將空鋁皿秤重並記錄,接著秤取CAPUD樣品1-2g置於鋁皿中,待其流平,再放置於加熱板上,以150°C烘烤15分鐘,最後再秤重(烘烤樣品+鋁皿)的重量,並計算其固含量。 固含量%=(烘烤樣品+鋁皿-空鋁皿)/未烘乾樣品重 Measurement of solid content : First weigh and record the empty aluminum dish, then weigh 1-2g of the CAPUD sample and place it in the aluminum dish, wait for it to level off, then place it on a heating plate, and bake at 150°C for 15 minutes , and finally weigh the weight of (baked sample+aluminum pan) and calculate its solid content. Solid content% = (baked sample + aluminum dish - empty aluminum dish) / undried sample weight

pH 值的量測:將CAPUD樣品於溫度25°C下恆溫1小時,再以pH計進行量測。 Measurement of pH value: Keep the CAPUD sample at a temperature of 25°C for 1 hour, and then measure it with a pH meter.

黏度的量測:將CAPUD樣品於溫度25°C下恆溫1小時,再以Brookfield,LVF #2,60rpm的條件進行量測。 Viscosity measurement : Keep the CAPUD sample at a temperature of 25°C for 1 hour, and then measure it under the conditions of Brookfield, LVF #2, 60rpm.

耐熱黃變性的量測:以CAPUD鍍鋅鋼板對應試樣於高溫烘烤前、後的色差程度作為判斷基準。在將實例2的CAPUD鍍鋅鋼板對應試樣置於烘箱前,先以色差儀測得各CAPUD鍍鋅鋼板對應試樣的b* 1值,將樣品置於150°C烘箱中烘烤30分鐘後取出,再次使用色差儀測得經烘烤後各CAPUD鍍鋅鋼板對應試樣的b* 2值,最後計算Δb值(即,b* 2- b* 1),以評估耐熱黃變性。 耐熱黃變性評價標準 Δb≦2 良好 O 2 < Δb < 3 尚可 Δ Δb ≧ 3 X Measurement of heat yellowing resistance : The color difference of the CAPUD galvanized steel plate corresponding to the sample before and after high temperature baking is used as the judgment standard. Before the corresponding sample of the CAPUD galvanized steel sheet of Example 2 is placed in the baking oven, the b* 1 value of each CAPUD galvanized steel sheet corresponding to the sample is first measured with a colorimeter, and the sample is placed in a 150°C oven and baked for 30 minutes After taking it out, use the color difference meter again to measure the b* 2 value of each CAPUD galvanized steel plate after baking, and finally calculate the Δb value (ie, b* 2 - b* 1 ) to evaluate the heat yellowing resistance. Heat yellowing resistance evaluation standard Δb≦2 good o 2 < Δb < 3 passable Δ Δb ≧ 3 Difference x

耐溶劑性的量測:用棉花沾取乙醇,接著使用耐磨試驗機(型號A20-339)以荷重1.0kg在實例2的各CAPUD鍍鋅鋼板對應試樣上,以含有乙醇的棉花來回進行擦拭5、10、15、20次,目視判斷有無失光。 耐溶劑性評價標準 20次未失光 良好 O 11~20次失光 尚可 Δ ≦10次失光 X Measurement of solvent resistance : dip cotton with ethanol, then use a wear-resistant tester (model A20-339) with a load of 1.0kg on the corresponding samples of each CAPUD galvanized steel sheet in Example 2, and use cotton containing ethanol to go back and forth Wipe 5, 10, 15, 20 times, and visually judge whether there is any loss of gloss. Solvent Resistance Evaluation Criteria 20 times without losing light good o 11~20 times loss of light passable Δ ≦10 loss of light Difference x

如表3所示,CAPUD樣品1~5及7的耐熱黃變性測試Δb值皆小於3;CAPUD樣品1~6及9經耐溶劑性測試可來回擦拭超過10次,而不失光。在上述樣品中,CAPUD樣品1~3具有顯著更佳的耐熱黃變性(Δb值小於2)以及耐溶劑性表現(可來回擦拭超過20次)。As shown in Table 3, the Δb values of CAPUD samples 1~5 and 7 are all less than 3 in the heat yellowing test; CAPUD samples 1~6 and 9 can be wiped back and forth more than 10 times without loss of gloss after the solvent resistance test. Among the above samples, CAPUD samples 1~3 have significantly better heat yellowing resistance (Δb value is less than 2) and solvent resistance performance (can be wiped back and forth more than 20 times).

CAPUD樣品4有機酸/無機酸的莫耳比為83.34,非基於理論限制,已發現當有機酸/無機酸的莫耳比大於50時,聚氨酯分子間的離子鍵及/或氫鍵的強度減弱,因此耐溶劑性不若CAPUD樣品1~3;樣品5的有機酸/無機酸的莫耳比為18.62,非基於理論限制,已發現當有機酸/無機酸的莫耳比(特別是甲酸/無機酸的莫耳比;參下段有關樣品6的說明)小於35時,CAPUD的抗氧化力減弱,因此耐熱黃變性不若CAPUD樣品1~3。The molar ratio of organic acid/inorganic acid in CAPUD sample 4 is 83.34. It is not based on theoretical limitations. It has been found that when the molar ratio of organic acid/inorganic acid is greater than 50, the strength of ionic bonds and/or hydrogen bonds between polyurethane molecules is weakened. , so the solvent resistance is not as good as CAPUD samples 1~3; the molar ratio of organic acid/inorganic acid of sample 5 is 18.62, not based on theoretical limitations, it has been found that when the molar ratio of organic acid/inorganic acid (especially formic acid/ When the molar ratio of inorganic acid; refer to the description of sample 6 in the next paragraph) is less than 35, the antioxidant capacity of CAPUD is weakened, so the heat yellowing resistance is not as good as CAPUD samples 1~3.

相較於樣品1,樣品6使用乙酸取代甲酸,有機酸/無機酸的莫耳比維持37.86,但樣品6的耐熱黃變性表現較樣品1者差,非基於理論限制,咸信此是因乙酸不具抗氧化特性之故所致。Compared with sample 1, sample 6 uses acetic acid instead of formic acid, and the molar ratio of organic acid/inorganic acid is maintained at 37.86, but the thermal yellowing resistance of sample 6 is worse than that of sample 1. It is not based on theoretical limitations. It is believed that this is due to acetic acid Due to the lack of antioxidant properties.

相較於樣品1~3,樣品7的耐溶劑性不良。非基於理論限制,咸信此是因樣品7僅使用甲酸作為中和劑,而甲酸無法在聚氨酯分子之間提供離子鍵及/或氫鍵之故。Compared with samples 1-3, the solvent resistance of sample 7 was inferior. Without being bound by theory, it is believed that this is due to the fact that Sample 7 used only formic acid as a neutralizing agent, which is unable to provide ionic and/or hydrogen bonding between polyurethane molecules.

相較於樣品1~3,樣品8的耐熱黃變性及耐溶劑性二者均不良。非基於理論限制,咸信此是因樣品8僅使用乙酸作為中和劑,而乙酸無法在聚氨酯分子之間提供離子鍵及/或氫鍵且不具備抗氧化能力之故。Compared with samples 1 to 3, both of sample 8's thermal yellowing resistance and solvent resistance were inferior. Without being limited by theory, it is believed that this is because sample 8 only uses acetic acid as a neutralizing agent, and acetic acid cannot provide ionic bonds and/or hydrogen bonds between polyurethane molecules and has no antioxidant capacity.

相較於樣品1~3,樣品9的耐黃變性不良。非基於理論限制,咸信此是因樣品9僅使用磷酸作為中和劑,而磷酸不具備抗氧化能力之故。Compared with samples 1 to 3, the yellowing resistance of sample 9 was poor. Without being bound by theory, it is believed that this is due to the fact that sample 9 only used phosphoric acid as a neutralizing agent, which has no antioxidant capacity.
