Abstract
Description
本創作係關於一種聚合物結構體，更特定言之，係關於一種具有薄的紫外光遮蔽層的熱塑性聚氨酯結構體。The present work relates to a polymer structure, and more particularly to a thermoplastic polyurethane structure having a thin UV light blocking layer.
聚氨酯是一類由多元醇及異氰酸酯聚合形成的重要聚合物，其中藉由原料比例的調配，可製造具有所需機械性質的材料，所述機械性質包括耐磨性、耐溫性、可撓性、延伸性等。聚氨酯已廣泛用於各種材料之中，例如塗料、彈性體、發泡材料、黏合劑、密封劑等。一般而言，聚氨酯可根據結構中芳香環之有無而概分成脂肪族聚氨酯與芳香族聚氨酯，其中芳香族聚氨酯在物化性質及加工性上較脂肪族聚氨酯來得優異，但芳香族聚氨酯的耐候黃變問題一直是工業上難以解決的問題。Polyurethane is an important polymer formed by the polymerization of polyols and isocyanates. By adjusting the ratio of raw materials, materials with required mechanical properties can be produced. The mechanical properties include wear resistance, temperature resistance, flexibility, Extensibility, etc. Polyurethanes are used in a wide variety of materials such as coatings, elastomers, foams, adhesives, sealants, and more. Generally speaking, polyurethane can be roughly divided into aliphatic polyurethane and aromatic polyurethane according to the presence or absence of aromatic rings in the structure. Among them, aromatic polyurethane is better than aliphatic polyurethane in terms of physical and chemical properties and processability, but the weather resistance of aromatic polyurethane is yellowing. The problem has always been an industrially intractable one.
US 7,910,642 B2提出藉由使用添加型紫外線吸收劑（ultraviolet absorbing agent，UVA）與受阻胺光安定劑（hindered amine light stabilizer，HALS）來嘗試解決上述問題，受限於添加型紫外線吸收劑與芳香族聚氨酯的相容性問題，添加型紫外線吸收劑的添加量有其上限，使得抗黃變的效果無法被顯著改善，因此仍無法徹底解決黃變問題，使得芳香族聚氨酯特別是在戶外物品上的應用長期以來仍一直受到限制。US 7,910,642 B2 proposes to try to solve the above problems by using additive UV absorber (ultraviolet absorbing agent, UVA) and hindered amine light stabilizer (hindered amine light stabilizer, HALS), limited by additive UV absorber and aromatic The compatibility problem of polyurethane, the additive amount of UV absorber has its upper limit, so that the effect of anti-yellowing cannot be significantly improved, so the problem of yellowing cannot be completely solved, making aromatic polyurethane especially on outdoor items Applications have long remained limited.
為使聚合物材料免受紫外線照射影響其性質，習知技術均係將紫外線吸收劑直接添加或反應至所欲保護之聚合物材料中。以此方式製得之聚合物材料的紫外線吸收成分係均勻分布於聚合物材料之整體，因此，即使實際上僅分布於聚合物材料表面附近的紫外線吸收成分可發揮抗紫外線之功能，仍須大量添加紫外線吸收劑至聚合物材料之整體，方能使聚合物材料表面附近的紫外線吸收成分含量足以抵禦紫外線。然而，大量添加紫外線吸收劑的結果不僅導致成本提高，更可能不利地影響聚合物材料之物化性質。尤其，對於具有高應用價值的透明或白色聚合物材料（如熱塑性聚氨酯），大量添加紫外線吸收劑將使得聚合物材料顏色在視覺上明顯受到影響，導致商業價值降低。此亦說明何以芳香族聚氨酯在物化性質及加工性上均較脂肪族聚氨酯來得優異，卻總因其耐候黃變問題而被排除使用於戶外物品上。In order to prevent the properties of polymer materials from being affected by ultraviolet radiation, the conventional technology is to directly add or react ultraviolet absorbers to the polymer materials to be protected. The UV-absorbing component of the polymer material obtained in this way is uniformly distributed throughout the polymer material. Therefore, even if the UV-absorbing component that is actually only distributed near the surface of the polymer material can exert an anti-ultraviolet function, a large amount is still required. Adding the ultraviolet absorber to the whole polymer material can make the content of ultraviolet absorbing components near the surface of the polymer material sufficient to resist ultraviolet rays. However, the result of adding a large amount of UV absorbers not only increases the cost, but also may adversely affect the physical and chemical properties of polymer materials. Especially, for transparent or white polymer materials with high application value (such as thermoplastic polyurethane), adding a large amount of UV absorbers will make the color of the polymer material significantly affected visually, resulting in a decrease in commercial value. This also explains why aromatic polyurethanes are better than aliphatic polyurethanes in terms of physical and chemical properties and processability, but they are always excluded from being used in outdoor articles because of their weather yellowing problem.
有鑑於上述技術問題，本創作提供一種創新思維，透過於聚合物材料表面形成薄的紫外光遮蔽層的方式提供一種複合式聚合物材料，可同時達到有效抗紫外線、低成本、以及對聚合物材料物化性質影響最小化等優點，進而可解決工業上長期存在之芳香族聚氨酯在戶外物品應用上的瓶頸。In view of the above technical problems, this creation provides an innovative idea to provide a composite polymer material by forming a thin UV shielding layer on the surface of the polymer material, which can simultaneously achieve effective UV resistance, low cost, and protection against polymers. The advantages of minimizing the influence of the physical and chemical properties of materials can solve the long-standing industrial bottleneck of aromatic polyurethane in the application of outdoor products.

3.2.3.3.2.3. 熱塑性芳香族聚氨酯試片的戶外日照耐候測試Outdoor sunshine weathering test of thermoplastic aromatic polyurethane test piece

表1：熱塑性聚氨酯試片之戶外日照耐候測試
由表1可看出，熱塑性芳香族聚氨酯的戶外耐光照黃變性係隨紫外光吸收劑的添加量增加而增強。如製備例1-1至1-4所示，當熱塑性芳香族聚氨酯的結構中包含衍生自化學式（1）化合物之結構單元時，ΔYI值數值較低，且數值隨添加量增加而減少。尤其，如製備例1-2至1-4所示，反應型紫外光吸收劑因於合成熱塑性聚氨酯時參與擴鏈反應，成為聚合物主鏈的一部分，因此在高添加量下仍無吐出問題，能賦予熱塑性聚氨酯良好的耐候性，可在戶外長期使用，顯示出更佳的耐候性及抗黃變性。相較於此，如參考例2及3所示，添加型紫外光吸收劑在高添加量下會發生吐出問題，無法在戶外長期使用。It can be seen from Table 1 that the outdoor light yellowing resistance of thermoplastic aromatic polyurethane is enhanced with the increase of the added amount of ultraviolet light absorber. As shown in Preparation Examples 1-1 to 1-4, when the structure of the thermoplastic aromatic polyurethane contains structural units derived from the compound of chemical formula (1), the value of ΔYI is low, and the value decreases with the increase of the added amount. In particular, as shown in Preparation Examples 1-2 to 1-4, the reactive ultraviolet light absorber participates in the chain extension reaction when synthesizing thermoplastic polyurethane and becomes a part of the main chain of the polymer, so there is still no problem of spit out at a high addition amount , can endow thermoplastic polyurethane with good weather resistance, and can be used outdoors for a long time, showing better weather resistance and yellowing resistance. Compared with this, as shown in Reference Examples 2 and 3, additive-type ultraviolet light absorbers have spit-out problems when they are added in high amounts, and cannot be used outdoors for a long time.

At elevated temperature, use dimethylacetamide (DMAC) to dissolve the thermoplastic aromatic polyurethanes of Preparation Examples 1-5 to 1-7 into a glue solution with a solid content of 20%, and then add methyl ethyl ketone (methyl ethyl ketone, MEK)/toluene diluted to a coating solution with a solid content of about 10%.
