specific Embodiment approach 1

[0012] Specific embodiment one: The phenolic ball / polypropylene composite material of this embodiment consists of 70% to 93% polypropylene by mass percentage, 5% to 15% maleic anhydride grafted polypropylene, and 1% to 20% phenolic ball And 0.1% ~ 3% antioxidant.

[0013] Compared with inorganic filler particles, the phenolic balls in this embodiment have lower density and lighter weight, and have excellent adhesion, wear resistance, high temperature resistance, chemical stability, electrical insulation, higher rigidity and modulus and other advantages, the application of phenolic balls to polypropylene products can improve the mechanical properties of products, reduce the quality of polypropylene products, reduce energy consumption, and achieve the purpose of environmental protection. At the same time, phenolic balls are used as organic fillers. Before adding polypropylene, Incorporates well into polypropylene during melt blending without surface modification.

specific Embodiment approach 2

[0014] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the phenolic ball / polypropylene composite material consists of 75% to 90% polypropylene by mass percentage, 8% to 12% maleic anhydride grafted polypropylene, It is made of 1%-12% phenolic ball and 0.1%-2% antioxidant.

specific Embodiment approach 3

[0015] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the phenolic ball / polypropylene composite material consists of 83% polypropylene by mass percentage, 10% maleic anhydride grafted polypropylene, 6% phenolic ball and 1% antioxidant.

Abstract

The invention relates to a phenolic aldehyde sphere / polypropylene composite material and a preparation method thereof, and particularly relates to a modified polypropylene composite material and the preparation method thereof, aiming at solving the problems of low rigidity and modulus of the existing modified polypropylene composite material. The phenolic aldehyde sphere / polypropylene composite material is prepared from the following components by mass percent: 70%-93% of polypropylene, 5%-15% of maleic anhydride grafted polypropylene, 1%-20% of phenolic aldehyde sphere and 0.1%-3% of antioxidant. The preparation method comprises steps of firstly, weighing the raw materials; secondly, stoving the polypropylene, washing and drying the phenolic aldehyde sphere; thirdly, uniformly mixing the raw materials in a low-speed mixer, then extruding the composite material by a twin-screw extruder, prilling and moulding so as to prepare the composite material. The phenolic aldehyde sphere / polypropylene composite material has good mechanical property, and can be used as materials of automobile accessories, electrical equipment and engineering construction.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a modified polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP), as a general-purpose polymer material, has become one of the most promising thermoplastic polymer materials due to its advantages of high strength, good heat resistance, low relative density, easy processing and low price. It has become the third largest general-purpose plastic after polyethylene and polyvinyl chloride. It is the fastest growing variety of plastics and is widely used in various aspects of the national economy. However, ordinary polypropylene has poor toughness and is easily brittle at low temperature, which limits the further application of polypropylene in many fields. Therefore, as the demand for polypropylene materials continues to increase and the requirements for the performance of polypropylene materials inc...
