Abstract

The invention relates to polypropylene adhesive resin with high strength and high oxygen barrier property and a preparation method thereof. The polypropylene adhesive resin comprises the following components in parts by weight: 65-82 parts of polypropylene, 10-18 parts of quartz fiber, 6-10 parts of mica powder, 12-20 parts of a compatilizer and 1-10 parts of a dioctadecyl ammonium salt, wherein the monofilament diameter of the quartz fiber is 6-12 [mu]m, the softening point of the quartz fiber is 550-630 DEG C, and the density of the quartz fiber is 2.35-2.72 g / cm<3>. The polypropylene adhesive resin has high strength and high oxygen barrier property under the compounding action of the quartz fiber, the mica powder, the polar compatilizer and the dioctadecyl ammonium salt, and is used forenhancing a polypropylene material, so the problems of poor transparency and poor oxygen barrier property of the polypropylene material are solved; besides, the preparation method of the polypropylene adhesive resin is simple in preparation process, uses easily-available raw materials and equipment and can realize large-scale production.

Description

technical field [0001] The invention relates to the technical field of manufacturing polypropylene adhesive resin, in particular to a polypropylene adhesive resin with high strength and high oxygen resistance and a preparation method thereof. Background technique [0002] Polymer-type polypropylene materials have a lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity. The impact strength of polymer-type polypropylene materials increases with the increase of ethylene content, while Strength decreases with increasing ethylene content. The Vicat softening temperature of the polymer-type polypropylene material is 150°C, and its Vicat softening temperature is relatively high, so the material has better dimensional stability when heated, the smaller the thermal deformation, the better the thermal deformation resistance. In addition, due to the high crystallinity of the polymer-type polypropylene material, this material has strong surface stiffn...
