Description
Technical field
The invention belongs to macromolecular material recovery technology field, be specifically related to a kind of recovery carbon fiber reinforced nylon matrix material and preparation method thereof.
Background technology
Carbon-fibre composite (CFRP) has the excellent performance such as light weight, high strength, high-modulus, be that other glass fibre reinforced composions are incomparable, be therefore widely used in the new high-tech industry fields such as aerospace, automotive industry, track traffic, new forms of energy, sports goods.Along with rapid development of economy, CFRP is at the usage quantity rapid growth of every field, and the waste resin producing also grows with each passing day, and composition in discarded CFRP non-degradable all, if be directly discarded in environment, can bring serious pollution to environment on the one hand; On the other hand, in these discarded CFRP, often contain the high added value carbon fiber of 60% left and right, and the production of carbon fiber is the process of a highly energy-consuming, if do not recycled also, will not cause the serious waste of resource.
Nylon is as a kind of engineering plastics, and it has good elasticity, and mechanical property is better, wear-resisting, and oil-proofness and processing characteristics are good, is therefore widely used in automobile, household electrical appliances, electronic apparatus, the fields such as machinery.But nylon is easily embrittlement in use, shock resistance is poor, water-intake rate is high, the defects such as thermotolerance and intensity are slightly low, in order to improve these performances of nylon, conventional method is by adopting the filling-modified nylon of glass fibre, improving its thermotolerance at present, reduce water-intake rate, and further strengthen mechanical property.And glass fibre density is larger, after filling-modified nylon, obtain composition density also significantly increases thereupon, this can cause the competitiveness of product in market to decline, simultaneously, be subject to the performance limitations of glass fibre own, adopt the properties of nylons of glass enhancing modified to improve limited, in the higher applications of some performance requriementss by restricted.In order further to improve the performance of modified nylon composite material, and make material modified lightweight, make it meet the application to the higher field of performance requriements, a kind of method is to adopt carbon fiber enhancing modified nylon, as described in patent CN201210124432, CN101831172, the matrix material preparing not only intensity is high, excellent performance, and also density is low; But new carbon fiber is expensive, this has also caused the nylon composite materials cost that obtains by its enhancing modified higher, and this has directly limited it and has been widely used.
Summary of the invention
Object of the present invention is exactly to provide recovery carbon fiber reinforced nylon matrix material of a kind of energy-conserving and environment-protective and preparation method thereof in order to overcome the defect of above-mentioned prior art existence.
