摘要

摘要:本文研究了地面轮胎橡胶(GTR)的表面处理对老化GTR/环氧复合材料吸水性能和拉伸性能的影响。采用10wt -%的NaOH溶液和1wt -%的硬脂酸(SA)丙酮对GTR进行处理。结果表明:GTR的加入提高了环氧复合材料的吸水率，降低了其抗拉强度和弹性模量;在干燥条件下，与未处理的GTR相比，NaOH-和sa处理的GTR的抗拉强度分别下降了4.8%和2.9%。然而，naoh和sa处理的GTR的加入分别使环氧复合材料的弹性模量提高了约8.4%和6.0%。对于老化的环氧树脂，由于基体的塑化和界面GTR/环氧树脂强度的降低，拉伸强度和弹性模量进一步下降。结果表明，sa处理的GTR性能优于naoh处理的GTR。

Water absorption and tensile properties of ground tire rubber/epoxy composites: effect of surface treatment

ABSTRACT This paper investigates the surface treatment effect of ground tire rubber (GTR) on the water absorption and tensile properties of aged GTR/epoxy composites. The GTR was treated using 10 wt-% NaOH solution and 1 wt-% stearic acid (SA) in acetone. The results showed that the GTR addition increased the water absorption and decreased the tensile strength and elastic modulus of epoxy composites. In dry condition, compared to the untreated GTR, the tensile strength of the treated GTR decreased by about 4.8% and 2.9% for the NaOH- and SA-treated GTR, respectively. Nevertheless, the addition of treated GTR increased the elastic modulus of epoxy composites by about 8.4% and 6.0% for the NaOH-and SA-treated GTR, respectively. For the aged epoxy, the tensile strength and elastic modulus decreased further due to the matrix plasticisation and degradation of the interface GTR/epoxy strength. It was found that the SA-treated GTR has better performance than the NaOH-treated GTR.

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
