Abstract
The invention provides a compatibilization chain extender, which is used for adding in recovery waste engineering plastics. The compatibilization chain extender mainly comprises the raw material components with the following mass portion ratios: 1 to 99 portions of styrene-based materials, 0 to 60 portions of acrylic materials, 1 to 80 portions of epoxy materials, 0.1 to 5.0 portions of initiator materials and 0.1 to 5.0 portions of chain transfer agent materials. The chain extender can effectively increase the molecular weight of the recovery waste engineering plastics, lowers the degradation during the processing, increases the melt strength, and improve the application value of the waste plastics.
Description
Technical field
The present invention relates to a kind of chain-expanding agent, particularly relate to a kind of chain-expanding agent that waste and old engineering plastics reclaim that is used for.
Background technology
Along with skyrocketing of oil price; the price of engineering plastics also skyrockets thereupon; this increases the cost pressure of the consumption manufacturer of engineering plastics greatly; therefore waste and old engineering plastics (PC, PBT, PET, PA) often have the situation about using that repeatedly reclaims; yet waste and old engineering plastics are after repeatedly reclaiming use; owing to reason molecular weight and molecular weight such as thermo-oxidative ageing are bigger, mechanical properties decrease is more serious, thereby causes the recovery result of use of engineering plastics not fully up to expectations.
For these reasons, be badly in need of a kind of a kind of material that can effectively promote the molecular weight of waste and old engineering plastics of exploitation, thereby promote waste and old mechanical performance of engineering plastic, reach the recovery result of use of waste and old engineering plastics.
Summary of the invention
The object of the present invention is to provide a kind of chain-expanding agent, it can effectively promote the molecular weight of the waste and old engineering plastics of recovery, reduces the degraded in the course of processing, increases melt strength, improves the use value of waste or used plastics.
For achieving the above object, a kind of chain-expanding agent provided by the invention, it mainly comprises following mass fraction proportion raw material component:
