style="text-indent:25px">玻璃鋼廢料的處理與回收一直是壓在復(fù)合材料產(chǎn)業(yè)鏈上的一座大山，這個(gè)問(wèn)題解決不好，將會(huì)導(dǎo)致熱固性復(fù)合材料的應(yīng)用受到極大的限制。盡管?chē)?guó)外在這方面已有成熟的經(jīng)驗(yàn)，但是在中國(guó)目前的經(jīng)濟(jì)結(jié)構(gòu)下，如何實(shí)現(xiàn)玻璃鋼廢料的可回收再利用，仍然需要業(yè)內(nèi)企業(yè)做出努力與探索。助劑號(hào)稱是化學(xué)工業(yè)的味精。助劑雖小，但是往往能起到四兩撥千斤的作用，小助劑解決大問(wèn)題。20多年以來(lái)，助劑在復(fù)合材料產(chǎn)業(yè)鏈中的應(yīng)用已經(jīng)越來(lái)越廣，人們對(duì)助劑的重視程度也越來(lái)越深入。隨著碳纖維市場(chǎng)的快速增長(zhǎng)，人們一直在思考一個(gè)問(wèn)題，通過(guò)什么技術(shù)手段能夠把不飽和樹(shù)脂引入碳纖維復(fù)合材料的應(yīng)用領(lǐng)域？</p><p> 不飽和聚酯樹(shù)脂的固化是線性大分子通過(guò)交聯(lián)劑的作用，形成體型立體網(wǎng)絡(luò)過(guò)程，但是固化過(guò)程并不能消耗樹(shù)脂中全部活性雙鍵而達(dá)到完全的固化度。也就是說(shuō)樹(shù)脂的固化度很難達(dá)到完全。其原因在于固化反應(yīng)的后期，體系粘度急劇增加而使分了擴(kuò)散受到阻礙的緣故。 </p> <p> 一般只能根據(jù)材料性能趨于穩(wěn)定時(shí)，便認(rèn)為是固化完全了。樹(shù)脂的固化程度對(duì)玻璃鋼性能影響很大。固化程度越高，玻璃鋼制品的力學(xué)性能和物理、化學(xué)性能得到充分發(fā)揮。（有人做過(guò)實(shí)驗(yàn)，對(duì) UPR 樹(shù)脂固化后的不同階段進(jìn)行物理性能測(cè)試，結(jié)果表明，其彎曲強(qiáng)度隨著時(shí)間的增長(zhǎng)而不斷增長(zhǎng)，一直到一年后才趨于穩(wěn)定。而實(shí)際上，對(duì)于已經(jīng)投入使用的玻璃鋼制品，一年以后，由于熱、光等老化以及介質(zhì)的腐蝕等作用，機(jī)械性能又開(kāi)始逐漸下降了。） </p> <p> 影響固化度的因素有很多，樹(shù)脂本身的組分，引發(fā)劑、促進(jìn)劑的量，固化溫度、后固化溫度和固化時(shí)間等都可以影響聚酯樹(shù)脂的固化度。 </p> <p> <br /> 有時(shí)施工溫度升高 10℃，可使凝膠時(shí)間縮短將近 1/2。如果施工環(huán)境溫度過(guò)低，易造成長(zhǎng)久的欠固化。</p><div

當(dāng)然也會(huì)有其他導(dǎo)致樹(shù)脂變黃的原因。總的來(lái)說(shuō)熱氧和紫外線是黃變的主要原因。采用飽和二元酸(或酸酐)代替芳香族二元酸(或酸酐)，雖然可以在一定程度上使樹(shù)脂顏色淺一點(diǎn)，但考慮到樹(shù)脂性能、成本等各方面的因素，所以此法也是不夠理想的。 </p> <p> 據(jù)**介紹，除了在生產(chǎn)、儲(chǔ)存過(guò)程中充惰性氣體盡可能隔絕與氧氣的接觸外，更有效的方法是添加抗氧劑與紫外線吸收劑，可有效地防止與延遲聚酯發(fā)生黃變。推薦的不飽和樹(shù)脂抗黃變解決方案是：選用不含胺類的抗氧劑，而采用主輔抗氧劑復(fù)配使用，主抗氧劑通常為受阻酚類，可以捕捉過(guò)氧化自由基；輔助抗氧劑則為亞磷酸酯類，在分解氫過(guò)氧化物的同時(shí)還能螯合金屬離子，防止樹(shù)脂氧化變色。如果想進(jìn)一步提高耐黃變、耐候性，建議再添加紫外線吸收劑進(jìn)去，添加紫外線吸收劑能有效***高分子材料，在紫外線作用下的黃變現(xiàn)象，且給產(chǎn)品提供優(yōu)異的保護(hù)作用，有效防止光澤的降低、裂紋、氣泡、脫層的產(chǎn)生，明顯提高產(chǎn)品的耐候性，與抗氧劑一起使用有很好的協(xié)同效應(yīng)。當(dāng)然抗氧劑與紫外線吸收劑的使用，并不能從根本上解決黃變問(wèn)題，但是在一定的范圍內(nèi)，還是能有效地防止不飽和聚酯產(chǎn)品氧化黃變，保持產(chǎn)品水色透明，提高產(chǎn)品的檔次。拉伸強(qiáng)度和斷裂延伸率的比較大值出現(xiàn)在樹(shù)脂固化度為 90%左右。湛江**固化劑廠家批發(fā)價(jià)</p><p style="text-indent:25px">后固化處理方法：可于 40℃下 2 小時(shí)，60℃下 2 小時(shí)。梧州M50固化劑廠商</p><p
