【摘要】：以尼龍66(PA66)為基體樹(shù)脂、玻璃纖維為增強(qiáng)體,選用馬來(lái)酸酐接枝聚烯烴彈性體(POE-g-MAH)為增韌劑并添加適宜復(fù)合添加劑,通過(guò)熔融共混的方法制備了一系列高強(qiáng)增韌尼龍材料。研究了增韌劑添加量及復(fù)合添加劑對(duì)材料力學(xué)性能的影響,并對(duì)其在常溫、低溫及高寒條件下的性能進(jìn)行研究,結(jié)合掃描電子顯微鏡(SEM)對(duì)復(fù)合材料的微觀形貌進(jìn)行表征。結(jié)果表明,隨著增韌劑添加量的增加,材料的拉伸強(qiáng)度、彎曲強(qiáng)度和無(wú)缺口沖擊強(qiáng)度逐漸降低,缺口沖擊強(qiáng)度逐漸增加,當(dāng)增韌劑添加量為6份時(shí)材料的綜合力學(xué)性能最優(yōu);在低溫處理時(shí)材料的性能變化主要發(fā)生在開(kāi)始處理的2 h內(nèi),且隨著低溫處理時(shí)間的延長(zhǎng)以及溫度的降低,材料的缺口沖擊強(qiáng)度均逐漸降低、無(wú)缺口沖擊強(qiáng)度均逐漸增加,且適宜復(fù)合添加劑的加入會(huì)改善材料的熱穩(wěn)定性以及玻璃纖維與基體樹(shù)脂之間的界面結(jié)合性。綜上所述:增韌劑添加量為6份,選用適宜復(fù)合添加劑制備材料中的玻纖與基體樹(shù)脂結(jié)合性更好,材料力學(xué)性能及耐高寒性能最優(yōu)。
[Abstract]:The maleic anhydride grafted polyolefin elastomer (POE-g-MAH) was used as the toughening agent and the suitable composite additive was added. A series of high strength toughened nylon materials were prepared by melt blending. The effects of the amount of toughening agent and the compound additives on the mechanical properties of the materials were studied, and the mechanical properties of the composites were studied at room temperature. The properties of the composites were studied under low temperature and cold conditions. The microstructure of the composites was characterized by scanning electron microscope (SEM). The results showed that the tensile strength of the composites increased with the increase of the amount of toughening agent. The bending strength and notched impact strength decreased gradually, and the notched impact strength gradually increased. When the content of toughening agent was 6 phr, the comprehensive mechanical properties of the material were the best. At low temperature treatment, the properties of the material mainly change within 2 hours of the initial treatment, and with the prolongation of the low temperature treatment time and the decrease of temperature, the notched impact strength of the material gradually decreased. The notched impact strength increased gradually, and the addition of suitable composite additives could improve the thermal stability of the material and the interfacial bonding between glass fiber and matrix resin. To sum up, the amount of toughening agent was 6 phr. The combination of glass fiber and matrix resin is better, and the mechanical properties and cold resistance of materials are the best.
