Abstract

The invention discloses a modified waste polyethylene pipeline special-purpose material, and a preparation method thereof. The modified waste polyethylene pipeline special-purpose material is composed of, by weight, 100 parts of waste recycled polyethylene, 3 to 30 parts of a composite toughening modifier, 3 to 5 parts of an inorganic filling material, 0.02 to 0.2 part of a cross-linking agent, 0.05 to 0.1 part of an anti-oxidant, 1 to 7 parts of a black master batch, and 0.1 to 0.5 part of an antifoaming agent; the composite toughening modifier is composed of waste tyre rubber powder, SBS, and LLDPE resin at a scientific and reasonable ratio. According to the preparation method, the optimized composite toughening modifier is used for improving crosslinking degrees of relative ingredients in the composite material system, increasing the tensile strength of the composite material system, controlling the gel content and fluidity of the modified material system, and optimizing the mechanical properties of the composite material system. Operation of the preparation method is simple; adaptability is high; the preparation method is convenient for industrialized production, is capable of reducing production cost, and reducing pollution of solid waste on the environment, and possesses significant economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of polymer materials, more specifically, to a composite toughening modifier and its preparation method and application. Background technique [0002] With the wide application of high-tech in the plastics processing industry, the plastics industry has developed by leaps and bounds. However, the increase in plastic consumption has led to a surge in the generation of waste plastics. Since waste plastics decompose or degrade slowly in nature, waste plastics cause huge environmental pollution (ie "white pollution"). In addition, with the rapid development of my country's economy, cars have entered thousands of households and have become a necessity in people's daily life. However, with the prolongation of the use time of automobiles, waste tires have piled up like mountains, which has become an important source of "black pollution". In order to protect and improve the environment, improve resource utilization ...
