Abstract
The invention discloses a compatilizer. The components and the weight portion thereof of the compatilizer are: 1 to 99 portions of styrene substances, 0 to 60 portions of acrylic ester, 1 to 80 portions of epoxy, 0.1 to 5.0 portions of initiator and 1 to 100 portions of elastomer. The invention adopts a polymer synthesizing means to effectively graft molecules with active radicals onto the elastomer, thereby improving the compatibility among different components, particularly ensuring the uniform distribution of polyolefin components in waste plastics, improving the mechanical properties of the waste plastics and recycling the waste plastics.
Description
Technical field
The present invention relates to a kind of compatilizer, particularly relate to a kind of reactive compatibilizers.
Background technology
Compatilizer also claims expanding material, polymer coupler, is a kind of additives for plastics of novelty.Compatilizer is compatible by block or grafting, the 3rd component that adds to improve more than two kinds the mutual exclusive polymkeric substance of blend between the polymer (usually, a kind of is polar polymer, and another kind is a non-polar polymer), and this 3rd component promptly is a compatilizer.And the effect of compatilizer is the consistency that increases by two kinds of polymkeric substance, makes it bonding force increase between two kinds of polymkeric substance, forms stable structure, makes disperse phase and external phase even, i.e. compatibilized.Why compatilizer can make the polymer-compatibleization of two kinds of different in kinds, is because have the cause that can carry out physics or chemically combined group respectively with two kinds of polymkeric substance in its molecule.
(PET PA) in nonexpondable process, contains a spot of incompatible polyolefin component to engineering plastics for PC, PBT, therefore causes mechanical properties decrease serious; And along with the development of plastics industry, waste or used plastics increases day by day, for the protection environment, carries out the resource circulation utilization, and development and the exploitation that waste plastics recovery utilizes technology all is being devoted in countries in the world, and global in recent years plastics recycling new technology emerges in an endless stream.
Compatilizer being applied to engineering plastics reclaiming, is to solve one of serious effective way of plastics mechanical properties decrease instantly.
