1.Fibre reinforced
It uses the high toughness of the fibre to bear more internal stress, relying on the plasticity of the PA6 base material resin material mobility and bonding with the fibre to transmit the internal stress.PA6 fibre reinforced material is more generally selected glass fibre fibre, and other carbon fibre, high purity graphite fibre, boron fibre, very fine metal material fibre, single crystal fibre and natural fibre.
2.filling enhancement
PA6 modification filling enhancement application of powder filler: carbon black, lightweight silica, calcium bicarbonate, calcium sulfate, active zinc oxide and so on. Powdered filler particles vibrant surface with more obvious suction PA6 polymer molecular structure of the chain’s ability to work with the chain of physics and chemical crosslinking, prompted by external forces, can be jointly distributed load, enhance the physical properties of the raw material, corresponding to reduce the probability of rupture of the raw material. The better the amphiphilicity between the filler particles and the PA6 molecular structure chain on the page, the greater the bonding and the more significant the enhancement effect.
Tim filling enhancement in improving the surface smoothness of raw materials, temperature resistance, production and processing characteristics of the field has a distinctive effect, and the integration of fibre reinforcement application, can reasonably enhance the PA6 raw material condensation reaction characteristics, to broaden the scope of its use.
3.copolymer modification, nano enhancement and other methods
PA6 copolymer modification and modification of blending toughened in a similar way, that is, in the epoxy resin convergence, will be a single PA6 and PA66, polyacrylonitrile, and other individual according to a certain ratio of mixing and joint efforts to convergence, to obtain the PA6 three-block polymer or modified polymers with both advantages, physical properties to obtain a significant increase.
PA6 nanotechnology enhancement of the common ways are: interlayer composite method, blending method (including melting blending, saturated solution or moisturising emulsion blending, machinery and equipment blending, etc.), the origin of the convergence or when the government dispersion polymerization, colloidal solution – suspected glue method.
