Abstract

The invention belongs to the technical field of nano materials, and particularly relates to a carbon nano tube / unsaturated polyester composite material and a preparation method thereof. The preparation method comprises the following steps: carboxylic acid and chloroformylation are carried out to the carbon nano tube, the carbon nano tube is modified by amino or hydroxyl acrylic ester compound, and the carbon nano tube which can carry polymerizable double bond. The modified carbon nano tube is dispersed in unsaturated polyester substrate, and cobalt iso-octoate and methyl ethyl ketone peroxide are adopted as an accelerating agent and a curing agent so as to prepare the carbon nano tube / unsaturated polyester composite material. The obtained composite material has higher heat stability and chemical stability. Compared with unsaturated polyester condensate which has same compositions and does not add the carbon nano tube, the volume resistivity of the cured composite material is reduced to 3 to 9 order of magnitude, and the surface resistivity is reduced to 3 to 8 order of magnitude. The invention has simple technique and more practicability. The composite material can be applied to the shell or coating of the equipment in the fields of manufacturing motors of electric appliances, chemical machines and the like.

Description

technical field

[0001] The invention belongs to the technical field of nanomaterials, specifically relates to the preparation technology of carbon nanotube composite materials, and refers to a preparation method of carbon nanotube / unsaturated polyester composite materials used as surface structure materials or coatings. Background technique

[0002] Since Iijima discovered carbon nanotubes in 1991, carbon nanotubes have been a research hotspot in recent years because of their unique structure, good electrical and mechanical properties. Carbon nanotubes have nanoscale diameters and micron-scale lengths, and the aspect ratio can reach 100-1000. They are extremely strong and have ideal elastic modulus. They are an excellent fiber material, and their performance is better than any current fiber. Therefore, it can be used as a superfiber for the reinforcement of advanced composite materials; because carbon nanotubes combine the semi-metallic properties of graphite with the quantu...
