蛭石是一種含鐵、鎂的鋁硅酸鹽類礦物質(zhì)，具有層狀結(jié)構(gòu)，層間有結(jié)晶水。它受熱膨脹時(shí)，會(huì)像水蛭一樣蠕動(dòng)，故名蛭石。蛭石經(jīng)過(guò)晾干、破碎、篩選，在850~1000的溫度下煅燒，顆粒會(huì)膨脹20倍以上，形成膨脹蛭石。其密度為80~200kg/m3，熱導(dǎo)率為（m·K），耐火性能強(qiáng)，吸聲、隔聲性能好，無(wú) 毒無(wú)味，是防火涂料的重要摻材。珍珠巖是一種玻璃質(zhì)巖石，經(jīng)破碎、篩分、預(yù)熱、瞬間焙燒，可膨脹至20倍左右，形成具有蜂窩泡沫狀結(jié)構(gòu)的膨脹珍珠巖。膨脹珍珠巖的質(zhì)量極輕，容重為80-250kg/m3，熱導(dǎo)率為(m·K)，具有保溫、隔熱、不燃、無(wú) 毒、化學(xué)穩(wěn)定性好等特性，也是防火涂料中的重要填料。無(wú)錫隧道防火涂料生產(chǎn)廠家對(duì)于家庭式的防火涂料來(lái)說(shuō)。具有環(huán)保的效果是必不可少的一部分。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

非膨脹型防火涂料非膨脹型防火涂料包括兩個(gè)類型，即：難燃性防火涂料和不燃性防火涂料難燃性防火涂料有乳膠類防火涂料和含難燃助劑的防火涂料，乳膠類防火涂料其乳膠本身為難燃性物質(zhì)，在加上些無(wú)機(jī)顏料就形成了防火涂料，含難燃性助劑的防火涂料大多先用鹵素使基料難燃化，然后再加難燃劑，含難燃劑的防火涂料一方面由于本身的難燃性，另一方面由于這些助劑與基料的相互作用，而具有防火性能。不燃性防火涂料主要為無(wú)機(jī)涂料，這種涂料是無(wú)機(jī)基料中加入一些無(wú)機(jī)顏料及配料而形成一種完全不燃燒的防火涂料，對(duì)于這種涂料還存在著耐水性，裝飾性較差，不易固化等缺點(diǎn)，有待解決。膨脹型防火涂料與非膨脹型涂料相比，二者都是對(duì)火焰有抑制作用，但從隔熱性能看，膨脹型防火涂料是優(yōu)于非膨脹型防火涂料。 </p><p> 在非膨脹型防火涂料的組成中必需含有阻燃（防火劑），如含磷、含鹵素的有機(jī)物（如十溴聯(lián)苯醚）、硼酸鈉、三氧化銻等。硼酸鈉尤其合用于用作乙酸乙烯系乳液的阻燃劑，其添加量按10%溶液計(jì)，以占聚合物的40%~60%為宜。三氧化二銻本身的阻燃能力并不算高，但當(dāng)它處在燃燒初期可以天生三氯化銻的情況下，例如在氯化石蠟并用，就會(huì)施展出優(yōu)勝的阻燃能力。為了獲得優(yōu)異的防火機(jī)能，除添加阻燃劑外，基料的選擇也很重要。因?yàn)辂u素（一般為氯和溴）和磷等元素對(duì)改進(jìn)防火性效果十分***，所以比較好選用含有這些元素的基料。例如，以氯乙烯或偏二氯乙烯共聚物乳液或氯化橡膠乳液作為基料**為優(yōu)勝。此外，要以選用磷酸三甲苯酯和β-三氯乙烯磷酸酯作為阻燃性增塑劑。膨脹型防火涂料的防火機(jī)理在于當(dāng)防火涂料的飾面層暴露于火焰上時(shí)，涂膜中的發(fā)泡性成分即受熱分解，形成隔熱性的海綿狀發(fā)泡層，從而阻止火焰的傳播。涂料中的防火助劑主要是發(fā)泡成分，包括碳源、發(fā)泡劑和有機(jī)氮化合物等，它們可以配合使用。鋼結(jié)構(gòu)防火涂料等級(jí)及厚度的標(biāo)準(zhǔn)與原理。</p><div
