Problems solved by technology

This patent uses carbon fiber and polytetrafluoroethylene as corrosion-resistant modifiers to optimize the performance of PP materials. At the same time, maleic anhydride grafted polypropylene is used as a compatibilizer. The added PE content is limited and does not have low-temperature resistance.

Abstract

The invention relates to a high-temperature resistance and high-compatibility mixed material. The mixed material is prepared from the following components in percentage by mass: 40-50% of copolymer PP, 40-55% of PE, 3-15% of compatilizer INTUNE, 0.5-2% of lubricant and 0.5-1.5% of antioxidant. The mixed material provided by the invention perfectly integrates the advantages of PP and PE, and has good compatibility, high low-temperature impact resistance and good performance in rigidity, toughness, chemical resistance, high-temperature resistance and processability; and a preparation method of the mixed material provided by the invention has the advantages of easiness in operation, low cost and good material performance and has an economic value.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-temperature resistant and highly compatible mixed material and a preparation method thereof. Background technique [0002] PP is one of the most widely used varieties of general-purpose thermoplastic resins, and is widely used in various fields of industrial production. PP is cheap and has excellent comprehensive properties, but the most prominent shortcoming that needs to be overcome is the low low-temperature impact strength, and it is prone to cracking under force when used in cold regions. [0003] At present, the common method is to add a toughening agent to PP. This method has no obvious improvement effect on low-temperature impact, and the cost is high, and the rigidity of the material decreases greatly. Adding PE to PP can also be used to improve low-temperature impact resistance. This method is the most simple and effective, and the cost is also low. How...
