Abstract

A resin rainbow grating belongs to the technical field of upholstery and relates to a rainbow grating. The main technical problem to be addressed by the utility model is to provide a resin rainbow grating, and the technical proposal includes a resin grating substrate and an aluminum film. The resin grating substrate is closely coated with the aluminum film to form a radioactive rainbow grating. The rainbow grating is easy to fabricate, suitable for mass production, cost-effective and widely applicable in the technical field of upholstery. When used together with lighting, the utility model can play an important role in urban lighting during the night.

Description

A kind of resin rainbow grating

One, technical field

The utility model belongs to decorate decoratees a kind of macromolecule resin rainbow grating that technical field relates to.

Two, background technology

Traditional decoration decoration technology has: ticker tape, mural painting, sculpture, greasepaint spraying, lamp box, mirror etc.In recent ten years, people are designed to the product for civilian use to the High-Tech result diffraction grating again, are used to decorate the decoration field.Diffraction grating produces the physics colours such as red, orange, yellow, green, blue, purple that two dimension is arranged in order under sunlight or light-illuminating, have with the visual angle different with far and near viewing distance, be presented at the moment be gorgeous, multicoloured vision innervation variation effect.Owing to be the physics glory, thereby never fade, iridescence forever is so be widely used in decoration decoration field.Traditional diffraction grating technology of preparing mainly contains: mechanical scratching grating, three kinds of holographic grating and replicas.But preceding two kinds of technical costs are very high, are used for decorating the decoration people and are difficult to bear.Generally all be to adopt clone method, grating by the preparation of machine engraving or holographic is as the motherboard grating, on glass substrate, make the epoxy resin grating by pressure sintering again, do to decorate and decorate usefulness, generally be used to visible region, be commonly called the rainbow grating, as shown in Figure 1, comprise glass substrate 1, epoxy resin grating layer 2, aluminium film 3.But this replica cost is still higher, do to decorate decorate with also being difficult on the market and see, be also shown in plastics on the market sometimes and make thin film grating, but this grating structure is poor shallow, diffraction efficiency is low, colour is unintelligible by stretching hot pressing, do not had an optimistic view of, almost do not have market prospects by people.So the rainbow grating of conventional method preparation is not so far almost accepted by people yet in decoration market.

Three, summary of the invention

Can be used by large-scale popularization in order to solve the rainbow grating, matter of utmost importance is to reduce the grating cost significantly, and the diffraction grating that is used for the spectrum light splitting technology is freed from high-tech area, moves towards daily life.In fact, the rainbow grating that is used to decorate decoration is only pursued the diffraction efficiency of grating in the visible region, and needn't make excessive demands the spectrum line quality and the precision of grating, thus be relatively low to the technical requirement of this class grating, the space of the cost that has substantial degradation.

The technical problems to be solved in the utility model provides a kind of resin rainbow grating, and the technical scheme of technical solution problem comprises resin optical grating substrate 4, aluminium film 5 as shown in Figure 2; Have linear grating groove on the resin substrate, form resin optical grating substrate 4, aluminium film 5 is the grating retes that closely apply on resin optical grating substrate 4.

Operation principle explanation: have the resin substrate grating of aluminium film to have the diffracting effect of reflective rainbow grating.

Good effect of the present utility model: product structure is simple, the diffraction efficiency height, and suitable for mass production, with low cost, because the grating base material is a macromolecule resin material, it is more in light weight than traditional glass substrate grating, impact resistance strong, good toughness.The single original screen panel of producing can arbitrarily be spliced into the large-area flat-plate grating, also can design, splice different shape, adapts under the different occasions and uses.Except that common decoration is used, particularly cooperate and do the colored illumination at night in city with light, give beautiful visual experience, extensive market prospects is arranged.

Fig. 2 is a side-looking structural representation of the present utility model

Five, specific embodiments

The utility model is implemented by structural representation shown in Figure 2.4 is resin optical grating plates among Fig. 2, the 5th, and the aluminium film; Resin optical grating plate 4 is to make prototype grating with modified polycarbonate, and it as one of mould inner surface, is formed with polymethyl methacrylate cast polymerization.Modification polycarbonate grating is to make prototype grating with commodity epoxy resin replica, and it as one of mould inner surface, is formed with modification polycarbonate cast polymerization.Aluminium film 5 is to aluminize at the polymethyl methacrylate grating surface with vacuum coating technology to form.

Claims (1)

1. a resin rainbow grating comprises: resin optical grating substrate, aluminium film; It is characterized in that having linear grating groove on resin substrate, form resin optical grating substrate (4), aluminium film (5) is to go up the grating rete that forms at resin optical grating substrate (4).
