Problems solved by technology

[0004] The raw materials of the above-mentioned lampshade body only include PC plastic, polyvinyl chloride and talcum powder, and its aging resistance is relatively limited, especially when the motorcycle is parked outdoors for a long time, it is easy to cause the lampshade of the headlight to age and change color and cause the lampshade to be transparent. The light rate is reduced and needs to be improved

Abstract

The invention discloses a lampshade of a motorcycle headlight and a preparation method thereof, and relates to the technical field of motorcycle accessories. The raw material of the lampshade includes the following components in parts by weight: 280-300 parts of polycarbonate; 80-100 parts of ethylene; 5-8 parts of titanium dioxide; 3-5 parts of anti-aging agent; 3-4 parts of plasticizer; 3-5 parts of silane coupling agent; 0.4-0.6 parts of surfactant. Titanium dioxide is an important inorganic chemical material, which has the characteristics of high UV resistance, good visible light transmission and high chemical activity. Titanium dioxide has good absorption ability to UVA (300-400nm) and UVB (280-300nm), and it will not decompose or change color after absorbing ultraviolet rays, because it is not only a filler to enhance mechanical properties, but also has ultraviolet absorption ability . Titanium dioxide can enhance the strength of the lampshade while improving its anti-aging performance. At the same time, anti-aging effect is combined with anti-aging agent to further effectively improve the aging resistance of the lampshade to ensure the light transmittance of the lampshade.

Description

technical field [0001] The invention relates to the technical field of motorcycle accessories, more specifically, it relates to a lampshade of a motorcycle headlight and a preparation method thereof. Background technique [0002] The headlight is a tool for vehicle lighting, which plays an important role in the safe driving of the vehicle. The light transmittance and impact resistance of the headlight lampshade are of great significance. [0003] The Chinese patent whose authorized notification number is CN104552965B discloses a process for preparing a lampshade for a car lamp. The lampshade for a lampshade includes a lampshade body and an anti-collision tape. Mix with talcum powder in a high mixer for 4-6 minutes, put the obtained mixture into a twin-screw extruder, melt and extrude to granulate under the condition of 250-280°C and 500rpm; among them, PC plastic, polyvinyl chloride The ratio of talcum powder and talcum powder is 3:1:0.05-0.15; (2) put it in an oven, and dr...
