【摘要】：藍(lán)寶石材料已經(jīng)成為目前各個(gè)領(lǐng)域的發(fā)展基礎(chǔ)。由于藍(lán)寶石具有優(yōu)異的力學(xué)性能而被廣泛的應(yīng)用,藍(lán)寶石所制成的器件的質(zhì)量、壽命和發(fā)光效率在很大的程度上都依賴于其表面質(zhì)量,所以目前藍(lán)寶石的加工重點(diǎn)就是如何能高效的獲得藍(lán)寶石表面質(zhì)量。針對(duì)單晶藍(lán)寶石這種大批量生產(chǎn)的硬脆難加工的材料能獲得無(wú)損超光滑表面,本文提出了藍(lán)寶石拋光所用樹(shù)脂銅盤的制作方法。以銅粒子和樹(shù)脂基體組成樹(shù)脂銅盤,通過(guò)選用不同的樹(shù)脂作為基體,使其向高耐熱和高耐磨等方向發(fā)展。將銅粉和聚酚氧樹(shù)脂共混制備聚酚氧／銅復(fù)合材料,考察了銅含量和銅粒徑對(duì)復(fù)合材料的力學(xué)性能、熱變形溫度和摩擦磨損性能的影響。實(shí)驗(yàn)結(jié)果表明：當(dāng)銅粒徑為300#時(shí),摩擦系數(shù)出現(xiàn)先增加后減小的趨勢(shì)。銅含量為70%時(shí),其熱變形溫度達(dá)到最高89.7℃,復(fù)合材料的力學(xué)性能和耐磨性較好；隨著銅粒徑的增加,其力學(xué)性能出現(xiàn)減小的趨勢(shì),其磨損率和摩擦系數(shù)隨著粒徑的增大逐漸減小。考慮綜合性能,選擇粒徑為300#作為復(fù)合材料的銅粒徑。以聚酚氧同甲階酚醛樹(shù)脂混合后作為樹(shù)脂基體,研究了聚酚氧/甲階酚醛比例、銅粒子含量對(duì)聚酚氧/甲階酚醛/銅復(fù)合材料力學(xué)性能及磨損性能的影響。結(jié)果顯示：當(dāng)聚酚氧：甲階酚醛為6：4,銅含量為70%,粒徑300#時(shí),復(fù)合材料的熱變形溫度達(dá)到最高,為115.7℃,同時(shí)具有最小的磨損率和摩擦系數(shù),說(shuō)明酚醛的最佳加入量為40%時(shí),會(huì)使得復(fù)合材料的綜合性能得到提升。
[Abstract]:Sapphire materials have become the basis of development in various fields. Sapphire has been widely used because of its excellent mechanical properties, and the quality of devices made of sapphire. Both lifetime and luminous efficiency depend to a great extent on their surface quality, So at present, the focus of sapphire processing is how to obtain the surface quality of sapphire efficiently. In this paper, the preparation method of resin copper disk used in sapphire polishing is put forward. The resin copper disk is composed of copper particles and resin matrix, and different resins are selected as the matrix. The polyphenoxy / copper composites were prepared by blending copper powder with polyphenoxy resin. The mechanical properties of the composites were investigated by copper content and copper particle size. The experimental results show that the friction coefficient increases first and then decreases when the copper particle size is 300#. When the copper content is 70, the thermal deformation temperature reaches the highest 89.7 鈩，
