Study on the epoxy cross-linking assistant agent in the protective coatings on the metallic yarn;

The effect of epoxy crosslinking agent EH on the color fixation of cotton directly dyed with natural brazilwood dye was analyzed by K/S value,FT-IR,X-ray,DSCTGA and acid-dissolving rate testing,and reaction kinetics experiment was performed using hematein as a substitution for brazilwood dye.

Through single factor and orthogonal experiments, it is discussed the effects of such factors as the concentration of emulsion silicide epoxy crosslinking agent EPSIB and additives, the baking temperature and time on the elastic crease wrinkle angle, the surface friction and the stiffness and flexibility of the finished silk.

In order to improve mechanical properties of soy protein isolate-based edible film,a kind of epoxy group cross-linking agents was added into the edible film,and the effect of different content of cross-linking agents on mechanical properties of soy protein isolate-based edible film was investigated.

NR latex cured with different peroxides curing systems was made, and an effect of different varieties and different addition of coagents on curing efficiency was discussed.

The effects of various coagent on property of hydrogenated nitrile butadiene rubber(HNBR)blends crosslinked by peroxide,and fillers on service lifetime of the twin lip seals were studied.

Polypropylene (PP) was modified by peroxide initiator and assistant crosslinker.

The effects of active curing coagent N,N′-bis(furfurylidene)acetone(VP-4) on the curing characteristics,mechanical properties,crosslinking densities,hot air aging resistance as well as compression set of EPDM cured by peroxide(DCP) were studied.
