    • Disclosed is a method for producing an epoxy nanocomposite material containing vapor-grown carbon nanofibers and an epoxy nanocomposite material produced thereby. The method comprises physically mixing 0.1-5.0 parts by weight of vapor-grown carbon nanofibers as reinforcing materials with 100 parts by weight of an epoxy matrix resin to disperse the carbon nanofibers in the epoxy matrix resin, adding a curing agent to the mixture, and curing the mixture. According to the disclosed method, the vapor-grown carbon nanofibers are physically mixed with an epoxy matrix resin without using any solvent. Thus, the vapor-grown carbon nanofibers are sufficiently dispersed in the epoxy matrix resin compared to the case of using a solvent. Therefore, it is possible to produce an epoxy nanocomposite material having excellent mechanical strength and low friction/wear properties at room temperature and excellent thermal properties even at high temperature. Also, the vapor-grown carbon nanofibers are cost-effective and, at the same time, used in an amount smaller than the amount of carbon nanotubes used to improve the physical properties of epoxy resin in the prior art, thus effectively reducing the production cost of the nanocomposite material.
    • 公开了一种制备含有气相生长碳纳米纤维和由此制备的环氧纳米复合材料的环氧纳米复合材料的方法。 该方法包括将0.1-5.0重量份气相生长碳纳米纤维作为增强材料与100重量份的环氧基体树脂物理混合,以将碳纳米纤维分散在环氧基体树脂中,向混合物中加入固化剂,以及 固化混合物。 根据所公开的方法,气相生长的碳纳米纤维与环氧基质树脂物理混合,而不使用任何溶剂。 因此,与使用溶剂的情况相比,气相生长的碳纳米纤维充分分散在环氧树脂基质树脂中。 因此,即使在高温下也可以制造在室温下具有优异的机械强度和低摩擦/耐磨性能的环氧纳米复合材料,并且具有优异的热性能。 此外,气相生长的碳纳米纤维是成本有效的,并且同时使用的量小于用于改善现有技术中的环氧树脂的物理性质的碳纳米管的量,因此有效地降低了生产成本 的纳米复合材料。

    • The present invention relates to a novel epoxy resin curing system comprising a cationic latent catalytic curing agent containing a hexafluoroantimonate, characterized by exhibiting no shrinkage of volume or inducing an expansion of volume during the curing reaction of the epoxy resin. By the use of the epoxy resin curing system comprising a cationic latent catalytic curing agent containing a hexafluoroantimonate, it is possible to inhibit the shrinkage of volume or to induce the expansion of volume during the curing reaction of the epoxy resin. The development of such curing systems made it possible to improve the dimensional stability and to remove the residual stress, which has caused problems for decades in the production of various molded articles. Furthermore, the curing systems according to the present invention have excellent adhesive properties, thereby making it possible to develop adhesives for accurate spatial infiltration.
    • 本发明涉及包含含有六氟锑酸盐的阳离子潜催化固化剂的新型环氧树脂固化体系,其特征在于在环氧树脂固化反应期间体积没有收缩或体积膨胀。 通过使用包含含有六氟锑酸盐的阳离子潜催化固化剂的环氧树脂固化体系,可以抑制环氧树脂固化反应期间的体积收缩或体积膨胀。 这种固化体系的发展使得可以提高尺寸稳定性和消除残余应力,这在各种模塑制品的生产中已经引起数十年的问题。 此外,根据本发明的固化体系具有优异的粘合性能,从而可以开发用于精确空间渗透的粘合剂。
