Description
Technical field
The invention belongs to automobile lamp technical fields, especially lens of car light, and in particular to a kind of car headlamp
Poly methyl methacrylate plastic lens and preparation method thereof.
Background technique
In automotive lighting field, using lens the object for being placed in its focus, focal plane or attachment can be carried out at
The characteristic of picture, realize dipped beam, distance light lighting pattern optical plan, be a kind of relatively common form, not only in traditional halogen
Plain light source, the occasion of high-pressure discharge light source are common, recently as the rise of LED light source, are also commonly used for LED light source
Closely, in the scheme of distance light automotive lighting.
With the continuous maturation of LED light source, the case where being conventionally used to brake lamp modulating signal lamps and lanterns, just towards being applied to head lamp
The occasion of illumination constantly promotes.After LED light source is applied to headlamps, one benefit of bring is exactly, relative to traditional
Halogen and gas photoelectricity light source can deserve to be called cold light source, the remote traditional light lower than with power of external heat radiation
Source, therefore heatproof plastic material lens more very different than glass just have ample scope for abilities, plastic material lens are light-weight with its
The characteristics of, promotion rate is quickly under the background of energy-saving and emission-reduction.But the refractive index of existing plastic lens is generally 1.3 or so,
Light transmittance is 90% or so, and refractive index, resistance to ag(e)ing and transparency are still undesirable, it is difficult to meet the needs of market.
Summary of the invention
One of the objects of the present invention is to provide a kind of poly methyl methacrylate plastic lens, have refractive index good, saturating
Lightness is high, light transmittance is high, the benefit performances such as ageing-resistant.
The second object of the present invention is to provide a kind of preparation method of poly methyl methacrylate plastic lens, this method
The plastic lens of preparation has that refractive index is good, transparency is high, light transmittance is high, the benefit performances such as ageing-resistant.
Specifically, first technical solution of the invention is as follows
A kind of poly methyl methacrylate plastic lens include: by parts by weight of raw materials
Further, further include,
5-8 parts of glass fibre；
8-10 parts of tantalum pentoxide.
Another technical solution of the invention is as follows:
A kind of preparation method of poly methyl methacrylate plastic lens, comprising the following steps:
Polymethyl methacrylate is dried into 4h in the blast drier of sealing, obtains dry poly-methyl methacrylate
Ester；
Dry polymethyl methacrylate is heated to molten condition, is added with stirring tantalum pentoxide, free radical draws
Agent and vinylsiloxane rubber are sent out, continues insulated and stirred 30-45min, obtains modified poly (methyl methacrylate)；
Ultraviolet absorbing agent and glass fibre are added in modified poly (methyl methacrylate), continuation insulated and stirred is uniform,
Obtain mixed raw material；
To in the mold of mixed raw material injected plastic lens, is demoulded after cooling and solidifying, obtain plastic lens.
It is further, described that by polymethyl methacrylate, dry 4h, drying temperature are in the blast drier of sealing
90℃。
Further, described that dry polymethyl methacrylate is heated to molten condition, heating temperature is 220 DEG C.
In conclusion the invention has the following advantages:
1. vinylsiloxane rubber is added in polymethyl methacrylate and is modified to it by the present invention, strand is improved
Rigidity, to improve modified poly (methyl methacrylate) anti-aging property；
2. the present invention in polymethyl methacrylate be added tantalum pentoxide it is modified, improve its refractive index and
Transparency；
3. glass fibre is added in polymethyl methacrylate and is modified to it by the present invention, optimization modeling is further increased
Expect the anti-aging property of lens.
