在建筑与工业设计领域，黑色始终被视为经典且高端的选择。然而在实际应用中，黑色往往伴随一个难以回避的问题——强吸热。
In architecture and industrial design, black has always been regarded as a classic and premium choice. However, in practical applications, black is often associated with one unavoidable issue — strong heat absorption.
01 从“高温黑色”到“冷黑科技”
夏季强日照条件下，传统黑色屋面或外墙表面温度可轻易突破70–80°C。这不仅带来明显的室内热负荷，还会引发一系列连锁反应：
空调能耗显著上升
基材热老化加速
涂层开裂、褪色风险增加
于是，一个现实问题摆在材料工程师面前：能否在保持“深黑外观”的同时，实现“低热吸收”?
答案来自一项关键材料技术——红外反射颜料。而凯得乐新材料正是这一领域的先行者与深耕者。
*Under intense summer sunlight, the surface temperature of traditional black roofs or exterior walls can easily exceed 70–80°C. This not only creates a significant indoor heat load, but also triggers a series of related problems: increased air-conditioning energy consumption, accelerated thermal aging of substrates, and higher risk of coating cracking and fading.*
As a result, material engineers face a practical challenge: Can a material maintain a deep black appearance while achieving low heat absorption? The answer lies in infrared reflective pigments — and Cadello (Kaidele) New Materials is a pioneer and deep practitioner in this field.
02 光谱的“双面戏法”
为什么同样都是黑色，普通炭黑让人感到灼热，而红外反射颜料却能保持清凉?
很多人默认“黑色=吸热”，这其实是对光谱作用的简化理解。实际上，太阳辐射能量主要分布在两个关键区间：
可见光（400–700 nm）：决定颜色表现
近红外（700–2500 nm）：约占太阳能量的50%，是热量来源的核心
Why do surfaces that appear equally black behave so differently — with conventional carbon black becoming extremely hot, while infrared reflective pigments remain noticeably cooler?
*Many instinctively assume that “black = heat absorption,” but this oversimplifies how the solar spectrum works. In reality, solar radiation energy is mainly distributed across two key wavelength ranges: visible light (400–700 nm), which determines color appearance, and near-infrared (700–2500 nm), which accounts for approximately 50% of solar energy and is the primary source of heat.*
03 冷黑颜料的材料科学基础
作为复合无机颜料(CICP / MMO)的典型代表，凯得乐新材料旗下的冷黑颜料并非性能偶然，而是源于其微观结构与电子行为的精确设计。
凯得乐新材料冷黑颜料具有极稳固的尖晶石晶体结构。这种结构决定了它不仅耐高温、耐候，还具备特定的电子排布。颜料对光的吸收由其内部电子跃迁决定，冷黑颜料的电子能级经过特殊“设计”，使其在太阳光照射时具备“双面性”：
可见光区：高效吸收高能量可见光粒子，呈现深邃、纯正的黑色。
近红外区：因能带间隙较窄，低能量近红外光线不足以触发电子跃迁，不会被吸收转化为热能，而是穿透颗粒或被直接反射
As a typical representative of Complex Inorganic Colored Pigments (CICP / MMO), Cadello (Kaidele) New Materials’ cool black pigments achieve their performance through precisely engineered microstructures and electronic behavior.
These pigments feature an exceptionally stable spinel crystal structure, providing outstanding heat resistance and weather durability. The electronic energy levels are specially engineered to create a “dual-response” behavior: in the visible light region, high-energy photons are absorbed for a deep black appearance; in the near-infrared region, lower-energy radiation is reflected or transmitted rather than converted into heat.
04 衡量标准：TSR 与节能效益
评价红外反射颜料好坏的关键指标是 TSR(总太阳反射比)。
使用凯得乐新材料优质冷黑颜料配制的深色涂层，其 TSR 可从普通涂料的10%以下提升至30%以上。这意味着：
直接降温：显著降低建筑物表面温度
节能降耗：室内空调制冷负荷可降低20%-30%
延长寿命：减少基材因热胀冷缩引起的开裂，保护建筑结构
*The key parameter for evaluating infrared reflective pigments is TSR (Total Solar Reflectance). Dark coatings formulated with high-quality Cadello (Kaidele) New Materials cool black pigments can increase TSR values from below 10% to over 30%, delivering direct cooling, energy savings of 20%–30% in cooling loads, and extended service life by minimizing thermal expansion and contraction cracking.*
05 应用：让城市更“凉快”的广泛选择
凯得乐新材料红外反射颜料的应用早已超越建筑屋顶，覆盖多个领域：
工业建筑：彩钢瓦厂房的降温神器
汽车涂料：减少暴晒后车内升温，保护皮质内饰
塑料领域：用于户外塑料建材、休闲家具，防止热变形、减缓老化
军事伪装：模拟植物红外特征，提升隐身效果
The applications of Cadello (Kaidele) New Materials’ infrared reflective pigments have expanded far beyond building roofs, including industrial buildings (cooling solutions for metal roofing), automotive coatings (reducing cabin heat buildup), plastics industry (preventing thermal deformation), and military camouflage (enhancing concealment performance).
06 科技，让色彩更有温度
