The service performance of engineering plastics, this just has higher requirement to filler grain.
Kaolin is the inorganic mineral of general filling-modified PA, and kaolin can be by certain specific base by modification
Group's grafting or cladding on the surface thereof, can either be compatible well with plastics macromolecule, also can satisfy the special of product and want
It asks, becomes " representative " of emerging functional material, the functionalization for improving engineering plastics utilizes.Kaolin powder filler is mixed into modeling
Material, particle are surrounded by plastic molecules, and particle surface has a significant impact to reinforcement efficiency by the degree that matrix moistens.It is not easy wet
The particle of profit is not easy to disperse, and is easy conglomeration, reduces its reinforcement efficiency.The binding force for improving kaolin and plastic interface, can
It is improved by adding certain wet substances of increase that help.Kaolin surface is modified, its surface and plastics are improved
Affinity interaction, improve kaolinic reinforcing effect, reduce kaolin network strength, to improve kaolinic dispersion effect,
Improve reinforcing effect.
