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 for motorcycle headlamps and a preparation method of the lampshade, and relates to the technical field of motorcycle accessories. The lampshade comprises, by weight, 280 to 300 parts of polycarbonate, 80 to 100 parts of polyvinyl chloride, 5-8 parts of titanium dioxide, 3-5 parts of an anti-aging agent, 3-4 parts of a plasticizer, 3-5 parts of a silane couplingagent, and 0.4 to 0.6 part of a surfactant. Titanium dioxide is an important inorganic chemical material and has the characteristics of high ultraviolet resistance, good visible light permeability, high chemical activity and the like. Titanium dioxide has good absorption capacity on UVA (300-400 nm) and UVB (280-300 nm), cannot be decomposed or discolored after absorbing ultraviolet rays, and hasultraviolet absorption capacity due to the fact that titanium dioxide is filler for enhancing mechanical properties, therefore, titanium dioxide can enhance the strength of the lampshade and improve the ageing resistance of the lampshade. Meanwhile, the anti-aging effect of the anti-aging agent is adopted for cooperation, so that the anti-aging performance of the lampshade is further effectively improved, and the light transmittance of the lampshade is guaranteed.

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...
