A special material for UHMWPE alloy volume-enhancing and toughening modified polypropylene bellows and its preparation method

Abstract

The invention discloses a UHMWPE alloy capacity-increasing and toughening modified polypropylene corrugated pipe special material and a preparation method thereof. 5-30 parts of toughening agent, 1-5 parts of fluidity modifier. The corrugated pipe produced by the special material of the present invention has the characteristics of good mechanical properties, good low-temperature impact resistance, high thermal deformation temperature, high thermal conductivity, good flame retardancy, good surface gloss and good production stability, etc. .

Description

technical field

[0001] The invention belongs to a UHMWPE alloy volume-increasing and toughening-modified polypropylene bellows special material and a preparation method thereof. Background technique

[0002] The high performance and engineering plasticization of general plastics is one of the most important pursuit goals in the field of polymer science and engineering research. Plastic toughening is one of the main means. The most commonly used and most effective toughening method is to introduce flexible polymers into the toughened matrix. When the system is impacted by external forces, it will absorb a large amount of impact energy by inducing the silver craze and shear yield of the matrix around the rubber particles, thereby improving the toughness of the matrix. A typical example of toughness is rubber toughened plastics. However, this type of method also has a fatal weakness, that is, although the toughness of the plastic matrix is ​​improved, it often results in a de...
