Problems solved by technology

[0003] Polypropylene (PP) has excellent physical properties such as light specific gravity, low price, good mechanical properties and easy processing, as well as solvent resistance and high temperature resistance. It is the fastest growing material among general plastics and is widely used in automobiles. In decorative parts and small household appliances, due to its own material, the light shell of the existing lighting lamp has strong light transmittance, and the light transmission of the light bulb causes light leakage from the light shell, resulting in waste of light and reducing the utilization of the light source of the light source. rate, for this reason, the present invention proposes a kind of modified polypropylene material and its preparation method and application

Abstract

The invention relates to the technical field of modified materials, in particular to a modified polypropylene material as well as a preparation method and application thereof, and provides the following scheme: the modified polypropylene material is prepared by mixing barium sulfate treated by a silane coupling agent, high-crystalline polypropylene, a compatilizer, titanium dioxide, an antioxidant and a lubricant to obtain a mixed material; and melting the mixed material at the temperature of 205-220 DEG C, and putting the mixed material in an extruder for extrusion and granulation to prepare the modified polypropylene material, wherein the temperature of a machine barrel of the extruder is 205-220 DEG C, the rotating speed of a screw is 400-600 r / min, and the vacuum degree is -0.04 to 0.1 MPa. The modified polypropylene material prepared by taking high-crystalline polypropylene as a modified base material and adding titanium dioxide, barium sulfate, the lubricant and the antioxidant has high surface glossiness and low light transmittance, and can well reduce light leakage of a lamp source and improve the light source utilization rate of the lamp when being applied to the illumination lamp or a lamp shell. Therefore, the problem of low light source utilization rate of the illumination lamp is solved.

Description

Technical field [0001] The present invention relates to the field of modified materials, in particular a modified polypropylene material and a preparation method thereof. Background technique [0002] As the daily consumables, the lighting equipment industry has the emergence of new light sources such as my country's economic and social, fluorescent, energy-saving lamps, LEDs, so that lighting fixtures have evolved, and everything works toward more energy-saving, greenery and environmental protection. ; [0003] Polypropylene (PP) has excellent physical properties, low price, good mechanical performance and easy processing, etc. Differences and small household appliances, the existing lighting lamp housing is due to their own material, the light transmittance, the lighting transmission of the lamp, resulting in light leakage, resulting in light waste, reduced light source utilization In this respect, the present invention has proposed a modified polypropylene material and a prepa...
