1. Introduction

　　Carbon fiber (CF) is a new type of fibrous material with a carbon content of more than 95% high strength and high modulus fiber. It is composed of flake graphite microcrystalline and other organic fibers in the direction of the fiber axial direction, and obtained by carbonization and graphitization. Carbon fiber "outer soft inside", the quality is lighter than the metal aluminum, but the strength is higher than steel, and has the characteristics of corrosion resistance, high modulus, is important material in the defence military industry and civilian aspect. It is not only the intrinsic characteristic of carbon materials, but also the soft and processability of textile fiber, which is a new generation of reinforcing fiber.

　　2. Performance introduction

　　Carbon fiber has many excellent properties, carbon fiber axial strength and high modulus, low density, high performance than, no creep, not resistant to ultra high temperature oxidation environment, good fatigue resistance, heat and electrical conductivity between non-metal and metal, small thermal expansion coefficient and anisotropy, good corrosion resistance, permeability good X-ray. Good thermal conductivity, electromagnetic shielding, etc.

　　The young's modulus is more than three times that of traditional fiberglass. Compared with kevlar, the young's modulus is about twice as large as that in the organic solvent, acid and alkali, and the corrosion resistance is prominent. Transparency Market Research, a forecasting firm, predicts that the global Market for carbon fibre will reach $3.73 billion by 2020.

　　3. Application of paint.

　　Conductive carbon fiber is a kind of high conductivity materials, and its comprehensive performance is excellent, with many other materials incomparable advantages, in addition to high electrical conductivity, it also has corrosion resistance, abrasion resistance, high temperature resistant, high strength, light weight and other characteristics, is widely applied. In coatings, we mainly use its high conductivity, which can be made into conductive coatings and antistatic coatings of various properties, and can significantly enhance the mechanical properties and corrosion resistance of coatings. Generally the specification of about 3mm is suitable in coating.

　　Most of the antistatic epoxy floor coatings in China are conductive powders, such as mica powders, which can increase the conductivity of coatings. Research has shown that this approach in solvent-based coating, the more applicable, but in the absence of solvent system to import electric performance can not meet the requirement of coatings, and powder to join increases oil absorption, cause a large paint viscosity, difficult to apply. But after the test, when the adding amount of solventless epoxy floor coating for 4 ‰, the surface resistance of the coating can achieve 104 Ω. By comparing with other conductive to add the cost of material, found in the conductivity of conductive carbon fibres (resistance) electrostatic coating significantly lower cost, a conductive add material, the cost is only about 20% of the original.
