【水性脂肪族聚氨酯面漆】与芳香族聚氨酯面漆的区别

　　导读：两种产品属于聚氨酯涂料的范畴，兼顾了聚氨酯中氨酯键（-NH-CO-O）的结构特性。一般由多异氰酸酯与多元醇结合而成。最终体现出优异的机械、装饰等性能。这也是聚氨酯类产品的通性，两者产品的突出点。

　　Takeaway: two products belongs to the category of polyurethane coating, both the ammonia ester bond in polyurethane (NH - CO - O) structural characteristics. By more commonly on the combination of isocyanate and polyol. Ultimately reflects the excellent mechanical properties, decoration, etc. This is also the connectivity of polyurethane products, both the bulge of products.

　　聚氨酯漆的综合优势

　　聚氨酯类涂料来自于内部氨酯键（-NH-CO-O）的强大特点，具有优异的机械性能、防腐性能和装饰性。颜色多样，光泽度可调，涂膜饱满切鲜影度高。这些提出的性能特点让它在国防、能源、化工、交通航天，甚至电器绝缘等领域中都有十分广泛的应用。

　　The comprehensive advantages of polyurethane paint

　　Internal ammonia ester urethane paint from the key (- NH - CO - O) strong characteristic, have excellent mechanical properties, anti-corrosion performance and decorative. Various color and luster is adjustable, full cut fresh shade degree of coating film is high. The performance characteristics of the proposed to make it in the defense, energy, chemical industry, transportation, aerospace, even in the field of electrical insulation and so on has a very wide application.

　　【水性脂肪族聚氨酯面漆】与芳香族聚氨酯面漆的测试

　　从结构数据上分析：脂肪族异氰酸酯：QUV，313nm，400h时,400h失光：10％；变色ΔE：1-2芳香族异氰酸酯：QUV，313nm，400h时,失光：95％；变色ΔE：5-15

　　从以上数据上来看，最大的差异性在于耐候性。所以，水性脂肪族聚氨酯漆用于户外耐候性的要求工程中，二芳香族聚氨酯面漆作为室内钢结构防腐涂装比较好。

　　From structural data analysis: aliphatic isocyanate, QUV, 313 nm, 400 h, 400 h lost: 10%; Discoloration Δ E: 1-2 aromatic isocyanate, QUV, 313 nm, 400 h, the loss of light: 95%; Discoloration Δ E: 5-15

　　From the above data point of view, the biggest difference lies in the weather. Waterborne aliphatic polyurethane paint for outdoor weatherability, therefore, the requirements of the project, the two aromatic polyurethane paint for interior steel structure anticorrosion coating is better.

　　【水性脂肪族聚氨酯面漆】与芳香族聚氨酯面漆最大的差异在于固化剂，芳香族异氰酸酯固化的聚氨酯涂料成为芳香族聚氨酯涂料。使用脂肪族异氰酸酯固化的称为脂肪族聚氨酯涂料。

　　waterborne aliphatic polyurethane paint and aromatic polyurethane paint the biggest difference lies in the curing agent, aromatic isocyanate curing polyurethane coatings become aromatic polyurethane coating. Use of aliphatic isocyanate curing called aliphatic polyurethane coatings.

　　【水性脂肪族聚氨酯面漆】与芳香族聚氨酯面漆性能差异

　　最主要的是耐受紫外线照射后分解成胺，芳香胺氧化后基团容易发色而脂肪族氨脂键稳定，而且即使分解成脂肪胺，也不像芳香胺容易变色。因为没有苯环共轭作为助色团，所以脂肪胺不易氧化，也不易泛黄。

　　The mainest is tolerance after ultraviolet irradiation decomposed into amines, aromatic amine oxide group after easy to hair color and stable aliphatic resin bond, and even if broken down into fatty amine, also don't like aromatic amine is easy to change color. Because there is no benzene conjugate as auxochrome, so fatty amine oxide not easily, also not easy yellowing.

　　【水性脂肪族聚氨酯面漆】的保光保色性，黏度和稳定性好。在紫外线外光和日光稳定的场合。例如汽车漆及许多高档户外工业面漆中有更加卓越的耐化学性以及良好的耐老化性。

　  waterborne aliphatic polyurethane paint of light colour, viscosity and good stability. In place of stable ultraviolet light and sun. Such as automotive paint and many high-end outdoor industrial paint has more excellent chemical resistance and good aging resistance.

　　但是【水性脂肪族聚氨酯面漆】不含苯基团，绿色更环保，也就贵一些。

　　But excluding waterborne aliphatic polyurethane topcoat   phenyl group, green environmental protection, more is expensive.
