Problems solved by technology

[0002] At present, in the field of traffic and safety, a large number of reflectors are used as warnings, signs, and signs. They have the function of reflecting light under light irradiation, and the patterns shown can be clearly seen. However, after lighting, it is difficult to distinguish or invisible at all. pattern, there is no warning and safety effect; the luminous film plate used in the security field in recent years has only a luminous function in the dark, but there is no reflective effect under the light so that the signs cannot be displayed immediately CN00119131.4, CN01119136.8
Since the production process of luminescence and reflection is relatively complicated, and the simple combination of the two materials will cause the luminescence and reflection to interfere with each other, the effect is unsatisfactory. For example, the luminescence and reflection signboard described in the invention patent CN00105909, two different coatings The layers are interlaced on the surface of the sign board; a kind of luminous and reflective motor vehicle number plate described in the utility model patent CN99217298 is a reflective vehicle number plate with a layer of characters engraved on the luminescent layer; described in CN91230230 The luminescent-reflective license plate is coated with luminescent paint on the bottom plate, and a reflective film is pasted on the place without characters or graphics; while the motor vehicle safety luminescent reflective dual-function ribbon described in CN96250899 has no reflective film and luminescent film on the adhesive layer
None of the above-mentioned prior art has a systematic and effective method to make a film plate with reflective and luminous functions

example 1

[0027] Example 1: This process is the first method to manufacture reflective luminescent panels with mesh patterns. Reflective paint formula:

[0028] Aluminum-coated hemispherical glass beads 30g

[0029] Transparent Ink 70g

[0030] Mix and disperse evenly to make a reflective paint, and print it on a yellow-green light-emitting board with a white bottom layer with a 150-mesh screen to form the part between the grids in the mesh pattern. When there is light, the "net" is yellow-green. The "blocks" between the nets are bright silver; after lighting, the "nets" emit yellow-green light in the dark to clearly show the entire pattern.

example 2

[0031] Example 2: This process is the third method to manufacture the reflective light-emitting film with mesh pattern. Luminous Paint Recipe:

[0032] Glow Powder 30g

[0033] Transparent Ink 70g

[0034] Mix it to make a luminous paint and print it on a white PVC base film with a 150-mesh screen to form the part of the mesh in the mesh pattern. Hemispherical glass microspheres are mixed and dispersed evenly with transparent ink, and overprinted on the above-mentioned PVC film on the part that is not printed with luminous paint, so that the reflective and luminous parts appear alternately. Mixing ratio of glass beads and transparent ink:

[0035] Glass beads 20g

[0036] Transparent ink 80g

[0037] Its effect is as in example 1

example 3

[0038] Example 3: This process is the second method to manufacture reflective light-emitting panels with traffic signs. First mix aluminum silver paste with transparent ink to make reflective coating, formula ratio:

[0039] Aluminum silver paste 10g

[0040] Transparent Ink 90g

[0041] The reflective paint is printed on the luminescent plate with a 200-mesh screen as a reflective layer.

[0042] The reflective coating made by mixing glass beads with a particle size of 20 microns and transparent ink is superimposed on the reflective layer with a 200-mesh screen as the pattern part of the traffic sign. Make the part printed with aluminum silver paste and glass beads reflect light, and the part not printed with light. When illuminated, the pattern of the traffic sign produces strong reflection and clearly presents the image of the pattern; after illuminated, the part outside the pattern emits light in the dark, and the pattern is also clearly displayed. The reflective paint...

Abstract

A process for preparing light-reflecting and luminos function film (or plate) features that the light-reflecting paint prepared from glass microbeads and transparent ink is printed on a base film (orplate) to constitute figure, pattern or marker; or the light-reflecting film and plate with different figures have the patterns and markers printed on them or carved on them.

Description

technical field [0001] The invention relates to a method for manufacturing a reflective and luminescent functional film and plate used in the fields of road signs or traffic signals, road surface markings, vehicle reflective luminous signs, reflective luminous advertisements and clothing. Background technique [0002] At present, in the field of traffic and safety, a large number of reflectors are used as warnings, signs, and signs. They have the function of reflecting light under light irradiation, and the patterns shown can be clearly seen. However, after lighting, it is difficult to distinguish or invisible at all. Pattern, just do not have warning, safety effect; The luminescent diaphragm plate that uses in the security field in recent years, only has luminescent function in the dark, and does not have reflective effect under light so can not show sign CN00119131.4, CN01119136.8 immediately. Since the production process of luminescence and ref...
