Abstract

The present invention relates to preparation of super tough nylon / ABS material by phenolformaldehyd resin dynamic sulfurication, it is composed of nylon, ABS material and phenolformaldehyde resin. The dynamic sulfurication technique makes the rubber phase in ABS proceed crosslinking and encloses the SAN phase, and uniformly distributed in continuous nylon phase, in addition, the phenolformaldehyde resin and nylon also proceeds reaction, thereby to obtain good compatibility of alloying system, uniform distribution of dispersed phase, small grain size, large binding force of phase interface, and forms the nylon / ABS alloy possessing good conprehensive properties. Advantages: simple technology, low cost etc.

Description

Technical field: [0001] The invention relates to a preparation method of a super-tough nylon / ABS alloy, belonging to the technical field of polymer materials. Background technique: [0002] Polyamide (Polyamide is abbreviated as PA, commonly known as nylon), has excellent properties such as high strength, wear resistance and self-lubrication, and is the engineering plastic with the largest output at present; however, nylon has the disadvantages of high water absorption, low temperature and notch sensitivity. Acrylonitrile / butadiene / styrene (ABS) resin is currently the most widely used polymer blend. ABS resin can be styrene, acrylonitrile grafted to polybutadiene, and then the graft is combined with styrene-acrylonitrile It is made by blending dilute nitrile (SAN) copolymer, or it can be made by blending SAN ternary with nitrile rubber (NBR), which organically combines the properties of polystyrene, polybutadiene and polyacrylonitrile It not only has the excellent mechanica...
