Abstract
The invention provides a high-temperature-resistant polypropylene pipe material and a preparation method thereof. The high-temperature-resistant polypropylene pipe material is prepared by comprising the following raw materials in parts by weight: 75 to 80 parts of polypropylene, 4 to 15 parts of glass fiber, 10 to 15 parts of an antistatic agent, 3 to 5 parts of a compatibilizing agent, 2 to 10 parts of a nanoscale inorganic filling material, 0.1 to 2 parts of a coupling agent, 0.5 to 1 part of an antioxidant and 0.5 to 1 part of PE wax. The high-temperature-resistant polypropylene pipe material provided by the invention has excellent physical and mechanical properties, especially has good high-temperature resistance, high-pressure resistance and corrosion resistance, can be used for a long time at a temperature of about 150 DEG C, and does not deform and crack; meanwhile, the preparation method is simple, has low cost and is applicable to industrial production.
Description
technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-temperature-resistant polypropylene pipe and a preparation method thereof. Background technique [0002] At present, plastic pipes are mainly made of single thermoplastics such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Pipes made of these thermoplastics generally have disadvantages such as poor heat resistance temperature, low strength, and low rigidity. In addition, in the field of chemical anti-corrosion equipment, polypropylene pipes are widely used, but their rigidity is low, and they are prone to deformation in high-temperature environments and during the process of transporting high-temperature substances. Therefore, how to improve the high-temperature resistance of polypropylene is an urgent problem in this field. technical problem. Contents of the invention [0003] In view of this, the present invention aims to propose...
