在建筑與工業(yè)設(shè)計(jì)領(lǐng)域，黑色始終被視為經(jīng)典且高端的選擇。然而在實(shí)際應(yīng)用中，黑色往往伴隨一個(gè)難以回避的問(wèn)題——強(qiáng)吸熱。
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 從“高溫黑色”到“冷黑科技”
夏季強(qiáng)日照條件下，傳統(tǒng)黑色屋面或外墻表面溫度可輕易突破70–80°C。這不僅帶來(lái)明顯的室內(nèi)熱負(fù)荷，還會(huì)引發(fā)一系列連鎖反應(yīng)：
空調(diào)能耗顯著上升
基材熱老化加速
涂層開(kāi)裂、褪色風(fēng)險(xiǎn)增加
于是，一個(gè)現(xiàn)實(shí)問(wèn)題擺在材料工程師面前：能否在保持“深黑外觀”的同時(shí)，實(shí)現(xiàn)“低熱吸收”?
答案來(lái)自一項(xiàng)關(guān)鍵材料技術(shù)——紅外反射顏料。而凱得樂(lè)新材料正是這一領(lǐng)域的先行者與深耕者。
*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 光譜的“雙面戲法”
為什么同樣都是黑色，普通炭黑讓人感到灼熱，而紅外反射顏料卻能保持清涼?
很多人默認(rèn)“黑色=吸熱”，這其實(shí)是對(duì)光譜作用的簡(jiǎn)化理解。實(shí)際上，太陽(yáng)輻射能量主要分布在兩個(gè)關(guān)鍵區(qū)間：
可見(jiàn)光（400–700 nm）：決定顏色表現(xiàn)
近紅外（700–2500 nm）：約占太陽(yáng)能量的50%，是熱量來(lái)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 冷黑顏料的材料科學(xué)基礎(chǔ)
作為復(fù)合無(wú)機(jī)顏料(CICP / MMO)的典型代表，凱得樂(lè)新材料旗下的冷黑顏料并非性能偶然，而是源于其微觀結(jié)構(gòu)與電子行為的精確設(shè)計(jì)。
凱得樂(lè)新材料冷黑顏料具有極穩(wěn)固的尖晶石晶體結(jié)構(gòu)。這種結(jié)構(gòu)決定了它不僅耐高溫、耐候，還具備特定的電子排布。顏料對(duì)光的吸收由其內(nèi)部電子躍遷決定，冷黑顏料的電子能級(jí)經(jīng)過(guò)特殊“設(shè)計(jì)”，使其在太陽(yáng)光照射時(shí)具備“雙面性”：
可見(jiàn)光區(qū)：高效吸收高能量可見(jiàn)光粒子，呈現(xiàn)深邃、純正的黑色。
近紅外區(qū)：因能帶間隙較窄，低能量近紅外光線不足以觸發(fā)電子躍遷，不會(huì)被吸收轉(zhuǎn)化為熱能，而是穿透顆粒或被直接反射
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 衡量標(biāo)準(zhǔn)：TSR 與節(jié)能效益
評(píng)價(jià)紅外反射顏料好壞的關(guān)鍵指標(biāo)是 TSR(總太陽(yáng)反射比)。
使用凱得樂(lè)新材料優(yōu)質(zhì)冷黑顏料配制的深色涂層，其 TSR 可從普通涂料的10%以下提升至30%以上。這意味著：
直接降溫：顯著降低建筑物表面溫度
節(jié)能降耗：室內(nèi)空調(diào)制冷負(fù)荷可降低20%-30%
延長(zhǎng)壽命：減少基材因熱脹冷縮引起的開(kāi)裂，保護(hù)建筑結(jié)構(gòu)
*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 應(yīng)用：讓城市更“涼快”的廣泛選擇
凱得樂(lè)新材料紅外反射顏料的應(yīng)用早已超越建筑屋頂，覆蓋多個(gè)領(lǐng)域：
工業(yè)建筑：彩鋼瓦廠房的降溫神器
汽車(chē)涂料：減少暴曬后車(chē)內(nèi)升溫，保護(hù)皮質(zhì)內(nèi)飾
塑料領(lǐng)域：用于戶外塑料建材、休閑家具，防止熱變形、減緩老化
軍事偽裝：模擬植物紅外特征，提升隱身效果
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，讓色彩更有溫度
在全球變暖和“雙碳”目標(biāo)的背景下，紅外反射顏料不僅是材料學(xué)的一大進(jìn)步，更是邁向綠色未來(lái)的重要一步。
凱得樂(lè)新材料憑借冷黑顏料核心技術(shù)，持續(xù)推動(dòng)深色材料向低碳、節(jié)能、耐候方向升級(jí)，為建筑、工業(yè)、交通等領(lǐng)域提供更環(huán)保的材料解決方案。科技，正在讓深色不再沉重，讓黑色也能“清涼”。
Against the backdrop of global warming and carbon neutrality goals, infrared reflective pigments represent not only a major advancement in material science but also an important step toward a more sustainable future.
With its core cool black pigment technology, Cadello (Kaidele) New Materials continues to drive deep-colored materials toward low-carbon, energy-saving, and high-durability directions, providing greener material solutions for architecture, industry, transportation, and beyond. Technology is giving color a new dimension — where even black can stay cool.
