Abstract

The invention discloses a high-performance engineering plastic / polyester type TPU alloy material. The high-performance engineering plastic / polyester type TPU alloy material comprises, by mass, 15 to 25 part of polyester type TPU, 30 to 60 parts of polymethyl acrylate, 20 to 45 parts of engineering plastic, 3 to 6 parts of phytosterol, 0.4 to 0.6 part of phthalic anhydride, 0.8 to 1.2 parts of polyvinyl alcohol, and 0.4 to 0.6 part of stannous octoate. According to a preparation method, polyester type TPU is adopted to solving problems that the fluidity of engineering plastics (AS, PS, ABS, PC, PBT, and PMMA) is poor, and infiltration of glass fiber by resin is not easily caused; a flow modifier and the phytosterol are added so improve glass fiber exposure and the interfacial strength of glass fiber with resin; and polyvinyl alcohol containing hydroxy is added to solve a problem that TPU molecular weight is reduced by processing.

Description

technical field [0001] The invention relates to the field of material science, in particular to a polymer material and a preparation method thereof. Background technique [0002] The engineering plastics selected by the present invention are AS, PS, ABS, PC, PBT, PMMA, all of which have good rigidity. It is difficult for these materials to obtain high-strength and high-toughness composite materials. They are all modified by adding glass fiber reinforced grafts containing elastomers, but their toughness is not greatly improved. For example: AS or PC is added The notched impact strength of the glass fiber is not as good as that of the raw material. At present, the use of long fiber reinforced technology can not only reduce the cost of materials, but also greatly improve the mechanical properties of materials and the phenomenon of "floating fibers"; but ordinary TPU has high viscosity, low melt index, poor fluidity and low hardness. , so that the preparation of polymethyl a...
