Abstract: The addition of nanometer accessory ingredient in the paint to improve the function of the traditional paint has been the hot topic in the field of anticorrosive paint research. In this paper, three kinds of water nanometer accessory ingredients including anti-abrasive cleaner, hydrophobing agent and anti-aging agent has been added into the paint to combine the nanometer denaturizing paint. The functions of nanometer denaturizing paint such as shellac’s adhesive force, resistance to water, resistance to alkali , and hydrophobic property were measured to evaluate the effect of the accessory ingredint according to the related test standard. It was found that the type and the quantity of nanometer accessory ingredient can effectively modify the function of the water paint. Finally, the optimum parameters were obtained.

Abstract: The wollastonite/PP composites were manufactured by twin-screw extruder and the effects of compatabilizer, feeding method and screw configuration on the properties of wollastonite/PP composites were investigated in this paper. The dispersion of fibrous wollastonite in PP matrix was determined by scanning electron microscope (SEM). The results showed that the strength, toughness and flowability of the composite were simultaneously guaranteed by using three different types of PP resins, and the interfacial adhesion was improved greatly by adding the compatabilizer of PP-g-MAH, which increases the comprehensive properties of wollastonite/PP composite. The fibrous dispersion of wollastonite in PP matrix was achieved by using of side feeding and the weak-shear screw configuration, which reaches the good reinforcing effect.
