Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a heat-resistant and crack-resistant polyethylene material 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, at the intersection of highways, urban roads, and overpasses. [0003] The commonly used material for water horses is high-density polyethylene, which has good recycling and reuse characteristics. Its hardness, tensile strength and creep are better than low-density polyethylene, but it is resistant to environmental stress cracking and thermal oxidation resistance. Low, which ...
