Abstract

The present invention relates to a method for preparing a film and a plate with the functions of reflecting light and emitting light. A film and a plate made from a photoluminescent material and resin and a resin light reflecting film with a microprism crystal structure are welded together by thermal pressure through a metal mould; the thermal pressure action of the projecting portion of the mould forming patterns, figures and marks destroys the crystal structure to form a transparent part so that a light emitting layer emerges. When the functional film and plate are irradiated by light or in darkness after illumination, patterns, figures or marks can emerge.

Description

Has manufacture method reflective and lighting function film, plate

Technical field

The present invention relates to a kind of manufacture method that is used for the reflective and lighting function film of having of fields such as road sign or traffic signals, pavement markers, the reflective luminous sign of vehicle, reflective luminous advertisement, plate.

Background technology

At present, use in a large number as the reflector of warning, indicating, identify, under rayed, have catoptrical function in traffic, security fields, pattern shown in can very clearly seeing, but after the illumination, just be difficult to distinguish or cannot see at all pattern, also just do not have caution, safety effect; The luminous lamina membranacea that uses in security fields in recent years has only lighting function in the dark, thereby and does not have reflection action show label (CN00119131.4, CN01119136.8) immediately under the illumination.Because luminous and reflective manufacture craft more complicated, and the simple assembly of two kinds of materials with, can make luminous, reflective interfering with each other, it is satisfactory that effect is difficult to; As described luminous, the reflecting sign board of patent of invention CN00105909, two kinds of alternate surfaces that are staggered in sign board of different coatings; The described a kind of light-light reflecting automotive number plate of utility model patent CN99217298 is to stick one deck character to be carved empty reflective number plate on luminescent layer; At the luminescent-glisten license plate described in the CN91230230, be to be coated with luminous paint, at no character code or figure place card reflective membrane at base plate; And the reflective difunctional colour band of the described motor vehicle safety light-emitting of CN96250899 is to be provided with reflective membrane and luminescent film at gluing layer.Above-mentioned prior art does not all have system and effective method to make to have reflective and lamina membranacea lighting function.

Summary of the invention

The present invention provides a kind of reflective and method lighting function lamina membranacea made, make the luminous reflecting lamina membranacea that makes to cut randomly, paste, easy to use, reflective under illumination, luminous in the dark after the illumination, pattern identification is remarkable, can be widely used in fields such as building, clothes, traffic, toy, safety.

Basic skills of the present invention is: use luminescent film, plate to stack with having the micro-prism structure reflective membrane, with being heated to the metal die that has designed decorative pattern and pattern having of uniform temperature both hot bondings are connected together, be that mould projection hot pressing function makes the crystal position structural failure of the corresponding microprism of reflective membrane and becomes transparent part and welded together with luminescent film, plate, transparent part just manifests luminescent film, plate, thereby has partly constituted decorative pattern and pattern, sign by transparent part and opaque microprism.

Described luminescent film, plate are to become luminous paint with embedded photoluminescent material and resin through mixing, grinding, deaeration, filtration, again with being coated in the method on the base resin plate and making, or master batch system film or the plate made with luminescent material and resin.The reflective membrane that has micro-prism structure is to reach reflection action by " prism " structure, and its material has PVC, PE, PP, PS, ABS, PMMA, PC, PET etc.That commonly used is PE, PVC, PP.This micro-prism structure is once meeting the heat bleach and losing reflection action.Metal die can be used electrical heating in the method for weld heating, and is wherein also available by thermal medium heating, also can add thermal weld with advanced person's high frequency, way such as ultrasonic.

This if desired product rigidity reflective, lighting function is better, can be with (promptly not with luminescent film, the plate one side of reflective membrane welding) to glue one deck base film layer, plate at its back side with bonding method by the product after the welding of luminescent film and reflective membrane, its material is a kind of in resin, leather, paper, fabric, wood, the metal etc.If the base layer of resin lamina membranacea that uses can place under the mould with luminous resin film, plate and reflective membrane, once heating is welded.

Because mould is hot pressing, can change the shape of mould protrusion or recessed part, obtain difform decorative pattern and pattern on the function lamina membranacea, as state decorative patterns such as transparent and opaque composition bar, lattice, net, pieces, also can with both one of constitute escape, traffic or warning picture.Like this reflective, lighting function lamina membranacea are seen decorative pattern, the pattern of being made up of silver color and Background luminescence layer under the normal lighting situation; In the dark under the light-illuminating, the strong reflection of reflector layer can know and manifest decorative pattern, pattern that luminous component decorative pattern, pattern also can obviously be found out in the dark to remove light.Can also be on above-mentioned dapple reflective, lighting function film, plate be stained with a warning mark of making by the film of carving characters or the pattern of commercial advertisement, also can obtain effect preferably with the method for pasting.

No matter this functional membrane, plate are by day, still lamp according to dark or lamp according to after dark in all play the demonstration effect, than in the prior art or have only reflection action, or have only the noctilucence effect, much superior.

Embodiment

Example one, produce field word pattern mold with the metallic copper material, make it be heated to 150 ℃ by electrothermal method, the reflective membrane that has micro-prism structure is put in carries out 5 seconds of hot pressing on the light-emitting area of luminescent film, plate, make two-layer combination firmly make the reflective luminescent film of continuous field word pattern.

Example two is produced the honeycomb pattern mould with the metallic zinc material and is made mold heated to 160 ℃ by high frequency, the reflective membrane that has micro-prism structure is put on the light-emitting area of luminescent film, plate to carry out hot pressing, makes for 10 seconds two-layer combination firm, makes reflective luminescent film.

Example three, produce the fishing net pattern mold with the metallic aluminium material, make mold heated to 170 ℃ by ultrasound wave heating, the reflective membrane that has micro-prism structure is put on the light-emitting area of luminescent film, also has a resin basement membrane under the luminescent film, carry out 10 seconds of hot pressing, make three-layered node close firmly, make the reflective luminescent film of fishing net shape.In the dark, between the yellow green net silver color blocky is arranged when lamp shines, remove lamp, luminous yellowish green mesh liner reveals luminous blocky.

Example four, aluminum have the mould of the traffic sign pattern of no thoroughfare, 150 ℃ of heating, make reflective membrane and can send out blue the luminescent film hot bonding of colour excess brightness to be connected together, and with adhering method it are sticked on the other traffic indication board of highway.

The sign that the yellow green no thoroughfare is arranged on the silvery white colour table face under daytime or normal light shine, at nightfall, before reaching, under the strong light irradiation, strong reflective this sign of clear demonstration on the plate face, in the dark after car sails, this sign sends blue streak, and caution must not be passed through.

Example five is pasted attachedly on it with cementing agent avy blue being scribed the plastics sign on the reflective luminous plaque that fishnet shape decorative pattern is arranged that example three is made, and constitutes non-luminous pattern and sticks on reflective, luminous plaque.
