Abstract

The invention discloses polypropylene composite plastic used for a water-filled barrier fence. The polypropylene composite plastic includes, by weight, 100-120 parts of polypropylene, 6-14 parts of nitrile butadiene rubber, 8-16 parts of chlorosulfonated polyethylene, 4-8 parts of a transparent nucleating agent, 2-4 parts of a crosslinker, 2-4 parts of gamma-glycidyl ether oxypropyltrimethoxysilane, 30-40 parts of filler, 2-4 parts of a dispersant, 2-4 parts of an antoxidant, 2-4 parts of a photo-stabilizer, and 2-4 parts of an ultraviolet absorber. Mica powder composite is prepared through the steps of: mixing polyhydroxybutyrate, mica powder, disproportionated rosin, tetradecanedioic acid and dibutyltin dilaurate, and heating and stirring the mixture to prepare the mica powder composite.

Description

technical field [0001] The invention relates to the technical field of polypropylene, in particular to a polypropylene composite plastic for water horses. Background technique [0002] The water barrier is a plastic shell obstacle used to divide the road surface or form a barrier. It is usually a structure with a small top and a large bottom. There are holes on the top for water injection to increase weight. Some water barriers also have horizontal through holes for passing rods Connect to form longer barrier chains or barrier walls. It is generally used in road traffic facilities, and is common in highways, urban roads, and intersections of overpasses and streets. The water horse is made of plastic. During its use, it is often exposed to wind, rain, and sun. Its surface becomes hard and brittle due to gradual aging during long-term use. When it collides or falls to the ground, It is prone to breakage and reduces the service life. [0003] Polypropylene plastic has the ad...
