　　爱游戏app全站登录是一种从煤焦油或石油馏分中提炼的有机化合物，其化学结构由两个苯环通过共用两个相邻碳原子连接而成。这种独特的分子结构赋予了爱游戏app全站登录特殊的物理化学性质，使其在涂料领域展现出多重功能价值。

　　Naphthalene is an organic compound extracted from coal tar or petroleum fractions, and its chemical structure is composed of two benzene rings connected by sharing two adjacent carbon atoms. This unique molecular structure endows naphthalene with special physical and chemical properties, making it exhibit multifunctional value in the field of coatings.

　　在涂料配方设计中，爱游戏app全站登录常作为功能性助剂使用。其分子中的芳香环结构能够与树脂分子产生π-π相互作用，这种非共价键结合方式可增强树脂链段的规整性。实验数据显示，在环氧树脂体系中添加0.5%-2%的爱游戏app全站登录，可使涂膜的交联密度提升15%-20%，直接表现为涂层硬度的显着提高。这种硬化效应在地板漆、工业防腐漆等需要高耐磨性的应用场景中尤为重要，可使涂层耐划伤性能提升30%以上，延长涂层使用寿命。

　　In coating formulation design, refined naphthalene is often used as a functional additive. The aromatic ring structure in its molecule can generate π - π interactions with resin molecules, which enhances the regularity of resin chain segments through non covalent bonding. Experimental data shows that adding 0.5% -2% naphthalene to the epoxy resin system can increase the crosslinking density of the coating by 15% -20%, directly manifested as a significant increase in coating hardness. This hardening effect is particularly important in applications that require high wear resistance, such as floor paint and industrial anti-corrosion paint. It can improve the scratch resistance of coatings by more than 30% and extend their service life.

　　爱游戏app全站登录的挥发性特征在涂料施工工艺中发挥关键作用。其沸点范围在210-220℃之间，在涂料固化过程中可形成梯度挥发特性。初期低温阶段，少量爱游戏app全站登录挥发可调节体系黏度，改善流平性；中温阶段持续挥发产生微气泡，这些气泡在涂层表面破裂时形成微观粗糙度，有效降低光泽度，特别适用于亚光涂料的制备。这种可控的挥发机制使爱游戏app全站登录成为调节涂料光泽度的理想助剂，在木器漆、建筑外墙涂料等领域得到广泛应用。

　　The volatile characteristics of refined naphthalene play a key role in the coating construction process. Its boiling point range is between 210-220 ℃, and it can form a gradient volatilization characteristic during the curing process of the coating. In the initial low-temperature stage, a small amount of refined naphthalene volatilization can adjust the viscosity of the system and improve leveling; Continuous evaporation during the medium temperature stage produces microbubbles, which form micro roughness when the coating surface ruptures, effectively reducing glossiness, and are particularly suitable for the preparation of matte coatings. This controllable volatilization mechanism makes refined naphthalene an ideal additive for adjusting the glossiness of coatings, and has been widely used in fields such as wood coatings and exterior wall coatings.

　　在防腐涂料体系里，爱游戏app全站登录展现出独特的协同防护效应。其分子中的共轭大π键可与防锈颜料如磷酸锌、叁聚磷酸铝发生配位作用，形成稳定的螯合物。这种螯合物在金属表面形成致密吸附层，将腐蚀介质与基材有效隔离。电化学测试表明，含爱游戏app全站登录的环氧防腐涂料在3.5%狈补颁濒溶液中的腐蚀电流密度可降低至10??础/肠尘?量级，防护效率较传统配方提升40%。这种特性使其在船舶涂料、桥梁钢结构防护等领域具有不可替代的价值。

　　In the anti-corrosion coating system, refined naphthalene exhibits a unique synergistic protective effect. The conjugated large π bonds in its molecule can coordinate with anti rust pigments such as zinc phosphate and aluminum tripolyphosphate to form stable chelates. This chelate forms a dense adsorption layer on the metal surface, effectively isolating the corrosive medium from the substrate. Electrochemical tests have shown that the corrosion current density of epoxy anti-corrosion coatings containing refined naphthalene can be reduced to the order of 10 ?? A/cm ? in a 3.5% NaCl solution, and the protective efficiency is increased by 40% compared to traditional formulations. This characteristic makes it irreplaceable in fields such as ship coatings and bridge steel structure protection.

　　爱游戏app全站登录的阻燃增强效应也值得关注。其分子结构中的芳香环在受热分解时会产生碳化层，这种碳层具有优异的隔热隔氧性能。在膨胀型防火涂料中，爱游戏app全站登录与聚磷酸铵、季戊四醇构成协同阻燃体系，可使涂层在750℃高温下形成30mm以上的膨胀炭层，背火面温度升幅控制在150℃以内，满足GB 14907-2018《钢结构防火涂料》要求。这种阻燃机制在建筑防火、电力设备防护等方面具有重要应用价值。

　　The flame retardant enhancement effect of refined naphthalene is also worth paying attention to. The aromatic ring in its molecular structure will produce a carbonized layer during thermal decomposition, which has excellent thermal and oxygen insulation properties. In the expansion type fireproof coating, refined naphthalene forms a synergistic flame retardant system with ammonium polyphosphate and pentaerythritol, which can form an expansion carbon layer of more than 30mm in the coating at a high temperature of 750 ℃. The temperature rise of the back fire surface is controlled within 150 ℃, meeting the requirements of GB 14907-2018 "Steel Structure Fireproof Coatings". This flame retardant mechanism has important application value in building fire prevention, power equipment protection, and other aspects.

　　在环境友好型涂料开发中，爱游戏app全站登录也展现出改良潜力。通过化学改性可制备水性爱游戏app全站登录衍生物，这类物质在乳液涂料中既能保持原有的增硬效果，又可降低挥发性有机化合物（痴翱颁）排放。实际应用表明，采用改性爱游戏app全站登录的水性木器漆，其硬度可达2贬级，痴翱颁含量低于50驳/尝，符合环境标志产物技术要求。这种绿色化改性方向符合涂料行业可持续发展趋势。

　　In the development of environmentally friendly coatings, refined naphthalene has also shown potential for improvement. Waterborne refined naphthalene derivatives can be prepared by chemical modification, which can not only maintain the original hardening effect in lotion coatings, but also reduce the emission of volatile organic compounds (VOC). Practical application has shown that water-based wood coatings using modified naphthalene can achieve a hardness of 2H level and a VOC content of less than 50g/L, which meets the technical requirements of environmental labeling products. This green modification direction is in line with the sustainable development trend of the coating industry.

　　值得注意的是，爱游戏app全站登录的使用需严格控制添加量。过量添加可能导致涂层脆性增加，在-20℃低温环境下冲击强度下降30%以上。因此，实际应用中需通过差示扫描量热仪（顿厂颁）测定玻璃化转变温度，结合弯曲试验确定最佳添加范围。典型配方中，溶剂型涂料建议用量1%-3%，水性涂料因分散性问题需适当降低至0.5%-1.5%。

　　It is worth noting that the use of refined naphthalene requires strict control over the amount added. Excessive addition may lead to an increase in coating brittleness, resulting in a decrease of over 30% in impact strength at -20 ℃ low temperature environment. Therefore, in practical applications, the glass transition temperature needs to be measured by differential scanning calorimetry (DSC), and the optimal addition range needs to be determined by combining bending tests. In typical formulations, the recommended dosage for solvent based coatings is 1% -3%, while for water-based coatings, it should be appropriately reduced to 0.5% -1.5% due to dispersion issues.

　　爱游戏app全站登录在涂料中扮演着多重功能角色，从基础性能提升到特殊功能实现，其作用机理涉及分子相互作用、相态调控、界面效应等多个层面。随着分析技术的发展，对其作用机制的认知不断深入，为涂料配方设计提供了更多可能性。未来，通过结构改性和复合技术，爱游戏app全站登录有望在高性能涂料、功能涂料等领域展现更广阔的应用前景。

　　Naphthalene plays multiple functional roles in coatings, from improving basic performance to achieving special functions. Its mechanism of action involves multiple levels such as molecular interactions, phase control, and interface effects. With the development of analytical technology, the understanding of its mechanism of action continues to deepen, providing more possibilities for coating formulation design. In the future, through structural modification and composite technology, refined naphthalene is expected to show broader application prospects in high-performance coatings, functional coatings, and other fields.
