Abstract

The invention discloses a polytrimethylene terephthalate enhanced composition. The enhanced composition comprises the following ingredients, by weight, 70%-90% of PTT, 5%-20% of inorganic filling material, 3%-8% of flexibilizers, 0.5%-2% of ultraviolet ray stabilizing agents, 0.1%-0.5% of nucleating agents, 0.1%-0.5% of coupling agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The inorganic filling material is wollastonite with an average length of 10-500 micrometers, with an average diameter of 3-30 micrometers and with a length/diameter of 3-100. The beneficial effects are that the composition has excellent enhancement, toughening and aging resistant effects, application effects of polytrimethylene terephthalate are raised, application fields of of polytrimethylene terephthalate are widened, and therefore the enhanced composition has good practical values and popularization prospects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a reinforced poly(trimethylene terephthalate) composition. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, films, engineering plastics, etc. Problems such as poor thermal performance and easy aging limit its application. Contents of the invention [0003] The purpose of the present invention is to provide a poly(trimethylene terephthalate) reinforced composition with good mechanical properties, strong aging resistance and good molding. [0004] The technical solution adopted by the present invention to solve the technical problem is: poly(trimethylene terephthalate) reinforced composition, and its components are proportioned by mass percentage: PTT 70%-90%, inorganic filler 5%-20%, Toughening agent 3%~8%, UV stabilize...
