摘要

物质有机非甘油(MONG)是相当大的废物输出(20% - 25%的粗甘油),通常由大豆生物柴油厂填埋。在这项工作中,大豆MONG的特点是作为一种共聚物的潜在用途,用于生产3D打印的长丝,目的是增加价值并将其从垃圾填埋场重新定向。作为一种共聚物,研究了MONG在降低天然纤维复合材料(NFC)合成聚合物含量方面的作用。尽管将MONG的一般热行为与复合应用中的热塑性聚合物进行了比较,但它取决于MONG的组成,这是一个取决于工厂排放废物的变量。为了提高MONG的热稳定性,我们评估了两种预处理方法(酸和酸 + 过氧化物)。酸 + 过氧化物预处理产生了稳定的浆料,其皂含量降低,结晶度增加,分子量低的小链脂肪酸,并与热塑性聚合物作为共聚物稳定共混。该处理增加了MONG中的甲酸(17.53%),与过氧化氢一起,导致环氧化反应,表现为氧环烷浓度增加(5.6%),评价处理后的MONG作为聚合物加工和3D打印的共聚物。

Utilization of residual fatty acids in matter organic non-glycerol from a soy biodiesel plant in filaments used for 3D printing

Matter organic non-glycerol (MONG) is a considerable waste output (20%−25% of crude glycerol) typically landfilled by soy biodiesel plants. In this work, soy MONG was characterized for potential use as a copolymer to produce filaments for 3D printing with an intent to add value and redirect it from landfills. As a copolymer, MONG was evaluated to reduce the synthetic polymer content of the natural fiber composites (NFC). Even though the general thermal behavior of the MONG was compared to that of a thermoplastic polymer in composite applications, it is dependent on the composition of the MONG, which is a variable depending on plant discharge waste. In order to improve the thermal stability of MONG, we evaluated two pretreatments (acid and acid + peroxide). The acid + peroxide pretreatment resulted in a stabilized paste with decreased soap content, increased crystallinity, low molecular weight small chain fatty acids, and a stable blend as a copolymer with a thermoplastic polymer. This treatment increased formic acid (17.53%) in MONG, along with hydrogen peroxide, led to epoxidation exhibited by the increased concentration of oxirane (5.6%) evaluating treated MONG as a copolymer in polymer processing and 3D printing.
