Abstract

The invention discloses polypropylene bonding resin with high strength and high fluidity. The polypropylene bonding resin comprises the following components in parts by weight: 60-81 parts of polypropylene; 12 to 20 parts of a polar compatilizer; 11 to 20 parts of talcum powder; 6-10 parts of paraffin particles; and 1-10 parts of quartz fiber; wherein the monofilament diameter of the quartz fiberis 6-12 [mu] m, the softening point is 550-630 DEG C, and the density is 2.35-2.72 g / cm<3>. According to the high-strength and high-fluidity polypropylene bonding resin, under the compounding action of the quartz fiber, the polar compatilizer, the talcum powder and the paraffin particles, the polypropylene bonding resin has high strength and high fluidity. In addition, the invention further discloses a preparation method of the polypropylene bonding resin, the preparation process is simple, raw materials and equipment are easy to obtain, and large-scale production can be achieved.

Description

technical field [0001] The invention relates to the technical field of manufacturing polypropylene adhesive resin, in particular to a high-strength and high-fluidity polypropylene adhesive resin 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 stiffness and good s...
