Description
Technical Field

Background
Polyvinyl chloride (PVC) is general plastic with high mechanical property, and a foam product of the PVC also has excellent properties of light weight, chemical corrosion resistance, flame retardance, rich raw material sources and the like. The production of polyvinyl chloride (PVC) foams is third place worldwide after Polyurethane (PU) and Polystyrene (PS) foams. At present, almost all known foam molding techniques are suitable for molding polyvinyl chloride foam. However, PVC cannot be used at higher temperatures due to its poor impact resistance, thermal deformation resistance and thermal stability, which greatly limits the range of applications for PVC foams. Therefore, the preparation of high-heat-resistance and high-performance PVC foam is a great hot spot in the foam research field nowadays. The N-phenylmaleimide (PhMI) -Methyl Methacrylate (MMA) -Acrylonitrile (AN) terpolymer is a novel material developed in the later period of 80 years, compared with the traditional high-molecular heat-resistant modifier, methyl methacrylate and N-phenylmaleimide in monomer components have good compatibility, the PMMA has high glass transition temperature, AN imide plane five-membered ring rigid structure (shown in figure 1) existing in AN introduced N-phenylmaleimide molecular chain is embedded into the high-molecular chain to completely prevent a side chain from rotating around a main chain, and the molecular chain has good heat resistance, rigidity, dimensional stability and toughness. At the same time, they are well compatible with various resins, non-toxic and have good thermal stability. The molecular main chain of the PVC resin contains polar groups, and the PVC resin has certain compatibility with AN N-phenylmaleimide (PhMI) -Methyl Methacrylate (MMA) -Acrylonitrile (AN) terpolymer, and carbonyl on a five-membered ring of AN imide plane and alpha-H on PVC have the capacity of forming special interaction (hydrogen bond) and promote the compatibility, so that the processing and impact resistance can be improved while the glass transition temperature and the thermal deformation temperature of a PVC foam plastic product are improved.
