Maleic anhydride graft compatibilizer is a kind of high molecular interface coupling agent, compatibilizer and dispersion promoter, which has high polarity and reactivity by introducing strong polar reactive group.
It is mainly used for halogen-free flame retardant, filling, glass fiber reinforcement, toughening, metal bonding, alloy compatibility, etc. It can greatly improve the compatibility of composite materials and the dispersion of fillers, and improve the product performance!
Maleic anhydride graft compatibilizer can be widely used in the following fields:
Flame retardant, reinforced, toughened, filled, bonded, metal bonded, plastic modified, plastic alloy, alloy compatible, engineering plastic modified, toughened impact resistant agent, PA / PE toughened adhesive layer, PA and other toughened
ABS / PC, PBT / PC and other alloys are compatible.
(1) Applied to plastic alloy
The appearance of compatibilizer mainly serves for polymer alloy technology. The so-called polymer alloy means that two or more polymer materials with different properties are blended and corresponding compatibilities are adopted
Multiphase and multicomponent system obtained by chemical technology. The compatibilizer is the key material of polymer alloy, blending and modification. The compatibilizer can adjust and control the microstructure of alloy technology, and make the blend achieve high performance and functionalization. Compatibilizers are widely used in PP / PE, PP / PA, PA / ps.pa/abs.abs/pc.pbt/pa.pet/pa.p
P / POE, PE / EPDM, TPE / PU and other alloys.
(2) modification of polymers
Because the compatibilizer is a bridge between the polar polymer and the non-polar polymer by adding the active free radical carboxyl into it, the compatibilizer can be modified into the polar modified polymer, and then it can be combined with the polar polymer
A good blending effect was obtained by the reaction between the two.
(3) Application in recycling waste plastics
Using compatibilizer to recycle waste plastic and make it a new plastic alloy or new modified plastic is a good and feasible method for “comprehensive utilization of waste” and can solve the problem of “white pollution”
Great social and enterprise economic benefits. There are many precedents in foreign countries, such as Bennet compatibilizer produced by national mining company of the Netherlands, which is a special compatibilizer for recycling waste plastics. Two or more kinds of used plastics with different properties, such as polyolefin plastics and engineering plastics, can be blended and recycled, and 5% – 10% compatibilizer can be added as the interface layer between marine and island phases,
A new type of plastic gold or modified plastic was prepared by using the binding force of compatibilizer and the efficiency of polar compatibilizer.
