Description
The technical field is as follows:
the invention relates to the technical field of vehicle exterior trimming parts, in particular to a vehicle exterior trimming part with a fluorescent effect.
The invention also relates to a method for preparing the vehicle exterior trimming part with the fluorescent effect.
Background art:
with the rapid development of the automobile industry and the continuous improvement and promotion of living conditions of people, automobiles become one of indispensable transportation tools for people to go out. The automobile keeping quantity is increased year by year, more and more people own private automobiles, and the popularization of automobiles brings development to the manufacture and design of automobile parts. Because the automobile has a complex structure and the range of related parts is very wide and complex, new innovation points are provided on the premise that the structure of each part is reasonable and the strength meets the requirements, so that more requirements of customers can be met.
The vehicle body exterior trim represents a trim of a vehicle type characteristic, and can play a role in beautifying a vehicle body. Traditionally, exterior parts such as B/C/D column decorative plates of a vehicle are mostly made of high-brightness black plastic parts to achieve the vehicle type joker effect and beautify the appearance of the vehicle. When the vehicle is in a bright environment, the shape and the exterior trimming parts of the vehicle can be observed and identified by people. However, when the vehicle is in a dark environment, the exterior parts other than the lamps (running lamp, brake lamp, fog lamp, etc.) cannot be clearly recognized by a person, and are easily touched by other vehicles, which may damage the vehicles. That is, the functions of the conventional exterior parts for vehicles are relatively simple, and further improvement is still needed.
The invention content is as follows:
the invention aims to solve the defects in the prior art, and provides a vehicle exterior trim with a fluorescent effect, which has the advantage of self-luminescence in a dim or dark environment and plays a role in safety warning for vehicles and pedestrians.
The invention aims to solve another technical problem of providing a preparation method of the vehicle exterior trimming part with the fluorescent effect.
The technical scheme adopted by the invention for solving the technical problems is as follows: the formula of the vehicle exterior trimming part comprises the following components in parts by weight: 100 parts of PMMA or ASA resin, 0.2-0.35 part of lubricant, 5.5-7.0 parts of toughening agent, 0.15-0.28 part of transparent black pigment, 2.8-3.5 parts of fluorescent agent, 0.2-1.0 part of dispersing agent and 0.4-0.5 part of antioxidant.
The fluorescent agent can absorb ultraviolet light and then emit bluish violet fluorescence which can be seen by naked eyes. The transparent black pigment can absorb the visible light spectrum, but does not absorb the ultraviolet light spectrum outside the visible light spectrum, so that the ultraviolet light can be transmitted, and after the fluorescent agent is added into the transparent black pigment, the ultraviolet light can penetrate through the transparent black pigment, so that the fluorescent agent can absorb the ultraviolet light, and visible fluorescence is emitted. The PMMA or ASA resin, the lubricant, the toughening agent, the dispersant and the antioxidant are all light-colored or colorless, and the main purpose is to enable ultraviolet light to smoothly penetrate through the PMMA or ASA resin, the lubricant, the toughening agent, the dispersant and the antioxidant, so that the fluorescent effect of the prepared automobile exterior trimming part is ensured to be optimal.
Preferably, the transparent black pigment is an aniline transparent black pigment. The aniline transparent black pigment has the best transparency, the light transmittance is far higher than that of other transparent black pigments, the visible light absorption performance is very strong, and the transmission performance for ultraviolet spectrums outside the visible spectrum is also very strong.
Preferably, the fluorescer is an inorganic sulphide fluorescer. The inorganic sulfide fluorescent agent has stable chemical property, and light absorption, light storage and light emission can be repeatedly carried out.
Preferably, the lubricant is paraffin or stearic acid.
Preferably, the toughening agent is ACR.
Preferably, the dispersant is a cationic wetting dispersant. The cationic surfactant has strong adsorption force and good dispersion effect on the aniline transparent black pigment.
Preferably, the antioxidant is a multi-hindered phenol type antioxidant. The multi-component hindered phenol antioxidant has good compatibility with most polymers.
The aniline transparent black pigment and the inorganic sulfide fluorescent agent are added into the formula of the exterior trimming part, and the aniline transparent black pigment has the largest overlapping degree between the wavelength range of ultraviolet light transmission and the wavelength range of ultraviolet light absorption of the inorganic sulfide fluorescent agent, so that the fluorescent effect of the product is optimal.
