TABLE 4 data for the examples and comparative examples
As can be seen from Table 4, the polystyrene-polyethylene alloy material prepared in the invention has tensile strength of not less than 28MPa, good solvent resistance and tensile strength retention of not less than 90%.
Comparing example 2, examples 5 to 6 and example 11, it can be seen that when the weight ratio of the low density polyethylene resin to the high density polyethylene resin is further adjusted to 2 to 3.
As can be seen from comparison of examples 6 to 10, when the weight ratio of the first compatibilizer to the second compatibilizer in the compatibilizers is further adjusted to 3.
From examples 12 to 16, it can be seen that the polystyrene-polyethylene alloy material prepared by compounding different compatibilizers and adopting different low-density polyethylene resin and high-density polyethylene resin has equivalent comprehensive properties.
As can be seen from comparative example 1, when only the low density polyethylene resin is used to improve the solvent resistance of the alloy material, the low density polyethylene resin has low molecular crystallinity, which results in slightly poor solvent resistance of the polystyrene-polyethylene alloy material, and the low density polyethylene resin has short molecular chains and high branching degree, which results in poor compatibility with the polystyrene resin, poor plasticizing uniformity of the system, and poor mechanical properties.
Comparing example 6 with comparative examples 2 to 3, it can be seen that when the weight ratio of the low density polyethylene resin to the high density polyethylene resin is too high, the obtained alloy material has low tensile strength and is very easy to deform during the molding and reprocessing processes, so that the plate material prepared from the polystyrene-polyethylene alloy material is very easy to have defects such as gallbladder folding and deformation during the application process; when the weight ratio of the low-density polyethylene resin to the high-density polyethylene resin is too low, the rigidity of the prepared alloy material is too high, and the ductility of the material is not enough, so that the risk of cracking and the like is easy to occur in the subsequent processing process.
Comparing example 6 with comparative examples 4 to 5, it can be seen that when the weight ratio of the first compatibilizer to the second compatibilizer in the compatibilizers is too low, the compatibility between the polystyrene resin and the polyethylene resin is poor, and the mechanical properties of the material are poor; when the weight ratio of the first compatilizer to the second compatilizer in the compatilizer is too high, the filler is unevenly dispersed in the system, stress concentration points are easily formed, and the mechanical property of the system is poor.
As can be seen from comparative example 6, the linear low density polyethylene resin and the high density polyethylene resin are compounded, because the processability of the linear low density polyethylene resin is poor, the system is not uniformly dispersed in the plasticizing process, and the mechanical property of the system is poor.
As can be seen from the comparative example 7, when the ethylene-acrylate-methacrylate glycidyl ester terpolymer is adopted in the compatilizer for compounding, the compatilizer has poor compatibility with polyethylene resin and polystyrene resin, so that the compatilizer is adhered to the surface of the filler to form micelles, stress concentration points are caused, the integral mechanical property is poor, the defects among molecular chains are large, and the solvent resistance is poor.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments.
