Embodiment 1

[0016] Take by weighing: 100 kilograms of homopolypropylene, 15 kilograms of basalt fiber, 6 kilograms of PP-g-MAH compatibilizer, 0.5 kilogram of di(dioctyl phosphite) tetraisopropyl titanate and trimethoxy [2- (7-Oxabicyclo[4.1.0]hept-3-yl)ethyl]silane 0.5 kg.

[0017] Stir and mix bis(dioctyl phosphite) tetraisopropyl titanate and trimethoxy[2-(7-oxabicyclo[4.1.0]hept-3-yl)ethyl]silane evenly to prepare Get coupling agent.

[0018] Dilute the coupling agent with 4 kg of isopropanol, and then evenly disperse it in the basalt fiber. The solvent is completely volatilized in an oven, and then the dried basalt fiber is crushed into fine powder with a pulverizer to obtain modified basalt fiber.

[0019] Then, the modified basalt fiber is uniformly mixed with homopolypropylene and PP-g-MAH compatibilizer, extruded and granulated, and then it can be prepared. Wherein, extrusion granulation is carried out at a temperature of 200° C. and a screw speed of 320 r / min. The injection m...

Abstract

The invention discloses basalt fiber enhanced polypropylene composite plastic for automobile interior parts. The composite plastic consists of the following components in parts by weight: 100 parts of homo-polypropylene, 10-20 parts of basalt fiber, 5-7 parts of a compatilizer and 0.8-1.2 parts of a coupling agent. The basalt fiber enhanced polypropylene composite plastic for automobile interior parts is excellent in chemical resistance, obvious in acid-alkali resistance, and enhanced in bending modulus, tensile strength and notch impact strength.

Description

technical field [0001] The invention relates to a plastic, in particular to a basalt fiber-reinforced polypropylene composite plastic for automotive interior parts. Background technique [0002] Polypropylene, abbreviated as PP, was first put into industrial production in Italy in 1957 and is another important plastic species after polyethylene (PE). It has good heat resistance, and it will not be destroyed when it is cooked at 135°C for 1000 hours. The specific heat capacity and thermal conductivity of PP are smaller than that of PE, but its thermal insulation is better than that of PE. PP is a non-polar polymer with excellent dielectric and electrical insulation properties. The electrical properties are basically not affected by ambient humidity and electric field frequency. Within the allowable operating range, the increase in temperature will reduce the electrical properties. Its High arc resistance. PP has good chemical resistance, and other reagents have no effect on...
