 automobile topcoat 四种 type 型:素 pigmented paint 、 metallic paint 、珍珠漆、珠光漆的色板对比

买车选Color时, sales 常提 to “这 is metallic paint “”那 is 珍珠漆”。所谓 topcoat ( pigmented paint /topcoat), is 决定车身Color and Appearance的那一层。它按 pigment 结构 main 分 for 素 pigmented paint 、 metallic paint 、珍珠漆、珠光漆四 type 。差别不 in “Color好不好看”,而 in pigment how to 让光发生反射 and 折射——这Direct决定了 gloss 、层次感、 price and 后期维护难度。

一句话概括:素 pigmented paint 靠纯 pigment 显色; metallic paint 靠铝粉产生随角异色;珍珠/珠光漆靠云母片产生幻彩柔光。越”闪”的漆越难调、越显划痕。

一、 topcoat is 什么, why 分这么多 type ?

topcoat is 涂 in intermediate coat of 上、 varnish of 下的着色层(见《 automobile paint coating layer 结构 analysis 》)。它不负责Rust-Proof也不负责保护,只负责”好看”。 for 了让好看有层次,Formula里加入了不同形态的效应 pigment ,于 is 分出了素色、 metal 、珍珠、珠光四大 type 。

二、四 type topcoat 的 pigment 原理

2.1 素 pigmented paint (Solid)

只有普通着色 pigment ,不含 metal 或珠光片。Color单一、均匀, from 任何角度看都一个样。优点 is 易Refinishing、 become 本低;缺点 is 不够立体。

2.2 metallic paint (Metallic)

in pigment in 加入铝粉( metal flakes)。铝粉像无数小镜子,随观察角度变化反射出明暗差异,形 become 随角异色(flip-flop)效应,让车漆有”深度感”。缺点 is 铝粉易被划伤显痕,且 color matching 对角度敏感。

2.3 珍珠漆(Pearl)

加入云母片外覆二氧化钛的珠光 pigment 。光线 in 多层薄膜间发生干涉,呈现幻彩、柔 and 的 color-changing 感(如白 in 透蓝、红 in 透金)。层次比 metallic paint 更细腻,但 color matching 最难、最贵

2.4 珠光漆

and 珍珠漆原理相近,强调更柔润、温润的 gloss ,常给人”丝绸感”。 in Premium and customization 车色 in common 。

type 型 效应 pigment Appearance feature 随角异色 维护/ become 本
素 pigmented paint 均匀、单一 低,易Refinishing
metallic paint 铝粉 有深度、闪烁 明显 in ,显划痕
珍珠漆 云母+TiO₂ 幻彩、细腻 高,难调
珠光漆 云母 type 柔润、丝绸感 in 强

三、Appearance and performance 的差异

  • metallic paint :立体感强、显档次,但铝粉外露,浅划痕 in 光下更明显,需依赖 varnish 保护。
  • 素 pigmented paint :朴素耐看,局部Paint RepairColor Difference更小, is 商用/工具车的 common selection 。
  • 珍珠/珠光漆:高级感最强,但Paint Repair时”驳口”最难做,对 spraying 角度 and film thickness 极敏感。

图:同一光照下, metallic paint 的闪烁 and 珍珠漆的幻彩各有质感,也各有维护难点。

四、维护 and Refinishing become 本

越”闪”的漆,Refinishing门槛越高:珍珠漆 need 精准控制 film thickness and spraying 角度,否则正侧光Color不一致; metallic paint 则要注意铝粉排列 direction 。这也 is for 何珍珠/ metallic paint 的Paint Repair费用通常高于素 pigmented paint 。日常养护上,所有 topcoat 都靠外层 varnish 抵御紫外线 and 划伤(见《 automobile varnish 的作用》)。

选色建议:追求性价比 and 好打理选素色;追求质感 and 档次选 metal ;追求独特高级感选珍珠/珠光,并预留更高的后期Refinishing预算。

五、 common 误区

误区 1:” metallic paint 比素 pigmented paint 更耐久”——耐久取决于 varnish 层, and is 否含铝粉无关。
误区 2:“珍珠漆就 is 更亮的 metallic paint “——两者 pigment 机理不同,珍珠靠云母干涉色,并非简单加亮。
误区 3:“Paint Repair只要Color号对就行”——效应 pigment 对 film thickness and 角度敏感,同色号也可能出现正侧光差。

总结

automobile topcoat 按 pigment 结构分 for 素色、 metal 、珍珠、珠光四 type :素色靠纯 pigment , metal 靠铝粉产生随角异色,珍珠/珠光靠云母片产生幻彩柔光。越具效应感的漆越显档次,也越难 color matching and 维护。选色时权衡美观、预算 and 后期Refinishing become 本即可。

FAQ FAQ

metallic paint and 素 pigmented paint 最大的 difference is 什么?
metallic paint in pigment in 加入了铝粉,随观察角度变化会出现明暗差异(随角异色),立体感强;素 pigmented paint 只有普通着色 pigment ,Color均匀单一。耐久方面两者都依赖外层 varnish ,差异不 in 寿命而 in 观感 and Refinishing难度。
珍珠漆 and metallic paint is 一回事吗?
不 is 。 metallic paint 用铝粉产生闪烁,珍珠漆用云母片外覆二氧化钛产生干涉幻彩,层次更细腻柔 and 。两者 pigment 机理不同,珍珠漆 color matching and Refinishing难度更高。
why metallic paint 的划痕更明显?
metallic paint 的铝粉分布 in 漆层 in ,浅划痕会破坏铝粉排列并 in 光下形 become 可见痕迹;素 pigmented paint 无明显效应 pigment ,小划痕反而不易察觉。保护仍靠Surface varnish 层。
哪种 topcoat 最好打理?
from 维护角度看素 pigmented paint 最易Refinishing、 become 本最低; metal and 珍珠/珠光漆观感更好但Paint Repair对 film thickness and 角度敏感,后期费用更高。日常都建议靠 varnish 保护 and 定期养护。
补珍珠漆 why 容易有Color Difference?
珍珠漆的云母干涉色对 spraying film thickness 、走枪角度 and 闪干Time极敏感,正光 and 侧光下Color会不同。Paint Repair时常用过渡 spraying (blending)Treatment驳口,对技师经验要求高。
