Abstract

The invention discloses an ionic liquid layered silicate / epoxide resin nano composite material which comprises the following raw material components in part by weight: 80 to 120 parts of epoxide resin, 1 to 10 parts of ionic liquid, 0.5 to 6 parts of layered silicate, 80 to 200 parts of curing agent and 0.5 to 2 parts of accelerator. The ionic liquid layered silicate / epoxide resin nano composite material has the advantage that compared with a conventional organic modifier, an imidazole and pyridine ionic liquid organic modifier has high heat stability and ultra-low saturation vapor pressure, has strong bonding force with layers of the layered silicate after being subjected to ion exchange and is beneficial for improving compatibility between the layered silicate and a polymer material, and mechanical property, heat stability and the like of the composite material.

Description

technical field [0001] The invention relates to a nanocomposite material and a preparation method thereof, in particular to an ionic liquid layered silicate / epoxy resin nanocomposite material and a preparation method thereof. Background technique [0002] A nanocomposite material is a composite material composed of two or more solid phases at least in one dimension at the nanoscale (1-100 nm). Epoxy resin (EP) is widely used in coatings, electronic appliances, etc. , civil construction and bonding and other fields. However, with the progress of society and the development of industry, the material performance requirements of various industries are getting higher and higher. The inherent shortcomings of epoxy resin, such as low impact strength, high brittleness, easy cracking, and poor medium and weather resistance, severely limit its use in the above aspects. Applications. In order to solve this problem, it is necessary to find an effective modification method to enhance ...
