Abstract

The present invention provides an amorphous composite material for melt extrusion molding and a preparation method thereof. The amorphous composite material is prepared from 100 parts of a resin base, 5-45 parts of nanometer nitrile rubber, 2-10 parts of a toughening agent, 4-10 parts of a heat stabilizer, 0.05 to 0.5 part of an antioxidant and 0.05 to 0.5 part of a lubricant. The prepared amorphous composite material for the melt extrusion molding innovatively employs a nanometer nitrile rubber modified acrylonitrile-bivinyl-styrene resin material, and has characteristics of high impact intensity, good hear resistance, fast molding speed and good oil resistance. In addition a preparation process of the composite material is simple. The amorphous composite material for melt extrusion molding can be directly applied to and popularized in the melt extrusion molding field and be used for preparing structural parts or outer parts having high requirements on toughness.

Description

technical field [0001] The invention belongs to the technical field of melt extrusion molding, and in particular relates to an amorphous composite material used for melt extrusion molding and a preparation method thereof. Background technique [0002] Melt extrusion molding is one of the common rapid prototyping methods. It uses heating wire instead of laser as the energy source, and uses fibrous or filamentous meltable material as raw material. Through heating and melting, the raw material is transformed from point to line, from line to surface and finally Complete the rapid construction of parts from surface to body. The advantage of this molding process is that the process is clean, easy to operate and does not generate garbage, and can be directly applied to office environments, especially in the field of modeling and model making in the initial stage of product design. [0003] One of the commonly used raw materials for melt extrusion molding is pure resin material, wh...
