Abstract

The invention provides a PPR material, which comprises the following components in parts by weight: 75-90 parts of a PPR raw material, 8-13 parts of glass fiber, 5-9 parts of matrix resin, 0.5-3 partsof a coupling agent, 0.5-1.5 parts of propyl gallate, 0.05-0.8 parts of an additive and 0.05-0.6 parts of a beta crystal form nucleating agent. The production process comprises the following steps: (1) uniformly mixing the PPR raw material, the matrix resin, the glass fiber, the matrix resin, the coupling agent, the propyl gallate, the additive and the beta crystal form nucleating agent in a mixer at a temperature of 160-200 DEG C; (2) feeding the mixture into a hopper of an extruder, setting the temperature at 205-220 DEG C, and pushing the mixture into a mould for forming products to form;and (3) cooling and pulling a tube blank to finally make a tube product. A PPR pipe obtained by the method is not only environment-friendly, but also has improved strength, and can be applied to environments with higher strength requirements. The preparation method has simple and easy-to-control technological process, used equipment is common equipment, and the preparation cost is low.

Description

Technical field [0001] The invention relates to a plastic pipe, in particular to a PPR material and its production process. Background technique [0002] In recent years, various polypropylene (PP) polymers have been widely developed and applied. Among them, random copolymer polypropylene (PPR) has received more and more attention due to its excellent comprehensive properties. growing. PPR is a type III PP developed by random copolymerization of ethylene monomer into the PP main chain. It is mainly used in industrial fields such as pipes, packaging bags, automotive components, and furniture. [0003] PPR plastic pipe is a new type of energy-saving and environmentally friendly building material. It has the advantages of hygiene, high temperature resistance, low price and long service life. It is widely used in construction and other industries in the market, but the strength of PPR pipe is not very high, making it The application is restricted. Summary of the invention [0004] In...
