Abstract

The invention relates to the field of a polypropylene-grafted composition, and discloses a poly(propylene-grafted polar monomer) composition and a preparation method thereof. According to the invention, the xylene insoluble substance content of the composition measured according to GB / T 18474-2001 is greater than or equal to 5 weight percentage; the peeling strength of the metal and the composition measured according to GB / T 2791-1995 is more than 50 N / 25mm; the VOC smell grade of the composition measured according to a German Volkswagen standard is less than or equal to 3.5; and the 100% tensile deformation recovery rate of the composition is more than 50%; by taking total weight of the composition as a reference, the silicate content is 0.1-5 weight percentage. The composition has high adhesion stress, high elasticity and little smell.

Description

technical field [0001] The invention relates to the field of polypropylene grafting compositions, in particular to a poly(propylene grafting polar monomer) composition and a preparation method thereof. Background technique [0002] Polypropylene (PP) is widely used due to its low price, easy recycling, small specific gravity, high surface hardness of finished products, high elasticity, heat resistance, chemical stability, and good insulation. [0003] Polypropylene grafted maleic anhydride is one of the important modification methods for polypropylene functionalization. The prepared PP-g-MAH is mainly used in various applications of polypropylene in the form of compatibilizers and binders, such as in When PP is blended with other polymers or inorganic fillers, PP-g-MAH mainly acts as a compatibilizer to reduce interfacial tension and improve the blending interface. The effect of the agent. However, as people's awareness of comfort and safety continues to increase, people's...
