Abstract

The invention provides a PP alloy material capable of releasing negative oxygen ions and a preparation method and application of the PP alloy material, and belongs to the field of high polymer material engineering. The PP alloy material capable of releasing the negative oxygen ions comprises the following components in parts by weight: 65-75 parts of carrier resin, 8-30 parts of a filler, 0.5-2 parts of a compatilizer, 2-15 parts of POE, 3-5 parts of negative ion powder and 0.5-2 parts of a lubricant. The carrier resin is composed of PP resin and PE resin, and the weight of added PE does not exceed 10% of the weight of the carrier resin. The PP alloy material capable of releasing the negative oxygen ions is excellent in mechanical property, can efficiently release the negative oxygen ions and can be effectively used for manufacturing household appliance parts or automobile plastic parts, the function of releasing the negative oxygen ions can be achieved only by replacing materials of corresponding parts, and therefore the PP alloy material has huge market space.

Description

technical field [0001] The invention belongs to the field of polymer material engineering, and in particular relates to a PP alloy material capable of releasing negative oxygen ions and a preparation method and application thereof. Background technique [0002] As one of the four general-purpose plastics, PP resin has excellent comprehensive properties, good chemical stability, good molding performance and relatively low price; but it also has strength, modulus, low hardness, and low temperature impact resistance. Disadvantages such as poor strength, large molding shrinkage, and easy aging. Therefore, it must be modified so that it can be adapted to the needs of the product. [0003] Reinforced plastics have the advantages of high specific strength, corrosion resistance, heat insulation, and low molding shrinkage. Adding fillers to PP resin can enhance the strength and thermal deformation resistance of PP resin, and can also reduce the thermal expansion coefficient of PP r...
