Abstract

The invention discloses an environment-friendly antistatic polypropylene plastic inspection well material restored and modified by a waste polypropylene molecular chain and a preparation method for the environment-friendly antistatic polypropylene plastic inspection well material. The environment-friendly antistatic polypropylene plastic inspection well material consists of the following components in percentage by weight: 36.4-76.2% of waste polypropylene, 3-6% of a molecular chain restoration agent, 2-5% of antistatic master batch, 5-15% of a flexibilizer, 10-30% of minerals, 3-5% of a compatilizer, 0.2-0.6% of an antioxidant, 0.2-0.4% of a light stabilizer and 0.4-1.6% of a lubricant. The environment-friendly antistatic polypropylene plastic inspection well material has the advantage that the polypropylene plastic inspection well material which is excellent in mechanical performance, cold resistance, heat resistance and antistatic effect is prepared by adopting the components of waste polypropylene, the molecular chain restoration agent, the antistatic master batch, the flexibilizer, the minerals, the compatilizer and the like; the waste polypropylene plastic can be greatly recycled because of the preparation of the material, the environmental pollution because of the waste polypropylene plastic and the resource waste are effectively solved, and an electrostatic problem generated in mounting and transporting processes of the plastic inspection well is completely solved, so that the safety of the plastic inspection well in engineering operation is greatly improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polypropylene material, in particular to an environment-friendly antistatic polypropylene plastic inspection well material repaired and modified by waste polypropylene molecular chains and a preparation method thereof. Background technique [0002] With the intensification of economic development and urbanization, the requirements for inspection well standards are getting higher and higher, and inspection wells have also developed from clay bricks, cement blocks, prefabricated concrete inspection wells to plastic inspection wells. Plastic inspection wells generally adopt one-time injection molding, which has fewer steps in the molding process, high output and stable quality. In 2006, my country issued the "Plastic Inspection Wells for Drainage in Construction Areas", which vigorously promoted the development of plastic inspection wells and gradually replaced traditional inspec...
