Abstract

The utility model discloses a reflecting film, belonging to the technical field of applied optics. The reflecting film comprises a composite layer and a cementing layer (6), and the composite layer is composed of a transparent resin layer (1) and a specular reflecting layer (7) which respectively coats a micro glass bead (2) and the cementing layer (6) is cemented with the composite layer. The improvement is that the cementing layer (6) is cemented with one side surface of the cotton paper layer (5) and the other side surface of the cotton paper layer (5) is connected with a light-cure pressure-sensitive glue layer (4). By adopting the cotton paper layer which has soft surface and good stretching and deforming performance and the light-cure pressure-sensitive glue layer which is connected with the cotton paper layer, the cemented area is increased when the reflecting film is cemented with the irregularity surface of the affixing object(such as signpost or road pile) through testing. Besides, the cementing is tight and smooth, the curing performance is high and the reflecting film is uneasy to fall off, and the connecting strength is also raised. Compared with the prior art, the service life of the reflecting film is raised about 50 percent.

Description

Reflective membrane

(1) technical field: the utility model relates to a kind of reflective membrane, belongs to the applied optics technical field.

(2) background technology: reflective membrane of the prior art, usually be used on the regional warning mark such as highway, railway, airport, military location, important place, warehouse (as sign board, road stake), by irradiate light especially night by the reflective membrane on the light-illuminating warning mark, play the light reflection and strengthen people visually to the identification of warning mark sharpness to reach.Described reflective membrane, its structure are to be connected with respectively on the clear polymer film (pet layer) by resin bed and reflecting layer covers to have the composite bed of glass microballoon and coupled cementing layer to constitute.It exists not enough: the one, because the double again connection carrier of doing reflective membrane of clear polymer film, skin hardness is hard and tension force is big; The 2nd, the reflective membrane cementing layer is a pressure sensitive, is glued to paste on the object still to be in pressure-sensitive state all the time, easily comes off; In the construction, (as sign board or road stake) is subjected to the influence on its uneven surface on the stickup object when the pressure-sensitive cementing layer of reflective membrane is connected in, the cemented surface of reflective membrane is difficult to tightly securely, and glue even fits on its rough surface, reduce reflective membrane cementing layer and the contact area of pasting the object gummed, reduced its strength of connection and serviceable life.

(3) summary of the invention: the purpose of this utility model is to overcome the deficiency that above-mentioned technology exists, and provides a kind of to increase it and to paste the contact area that the object gummed is connected, and improves the reflective membrane in its strength of connection and serviceable life.

For achieving the above object, the technical scheme of the utility model reflective membrane is achieved in that and comprises by transparent resin layer and specular layer and be coated with composite bed that glass microballoon forms respectively and constitute with cementing layer that its gummed joins; Its improvement is: described cementing layer is connected with the side surface gummed of cotton paper layer; Opposite side surface at described cotton paper layer is connected with the photocuring pressure-sensitive adhesive layer.

The utility model is taked above-mentioned articulamentum structure, by adopting the good cotton paper layer of soft surface and stretcher strain as the connection carrier layer, has realized replacing the hard and big connection carrier of tension force---the clear polymer film (pet layer) of skin hardness of the prior art.Reflective membrane photocuring pressure-sensitive adhesive layer is connected with stickup object gummed, and the effect generation photosynthetic response by UV sunlight can make it curing fast and be connected on the stickup object.After tested: be connected in the uneven surface of pasting (as sign board or road stake) on the object when the reflective membrane cementing layer glueds joint, its gummed connects area to be increased, glue together that tightly plain, curable is strong, difficult drop-off, improved its strength of joint, compare with prior art, improve about 50% its serviceable life.

(4) description of drawings: Fig. 1 is the utility model cross section zoomed-in view.

(5) embodiment: shown in Figure 1.This reflective membrane comprises by transparent resin layer 1 and specular layer 7 being coated with composite bed that glass microballoon 2 forms respectively and constituting with cementing layer 6 that its gummed joins; The one side surface gummed of the cotton paper layer 5 that described cementing layer 6 and soft surface and stretcher strain are good joins, and is connected with photocuring pressure-sensitive adhesive layer 4 on the opposite side surface of described cotton paper layer 5.For the photocuring pressure-sensitive adhesive layer 4 that prevents reflective membrane deposit or transportation in be subjected to temperature or environmental pollution to influence its cohesive strength, being connected with adherent layer 3 on the opposite side surface of described photocuring pressure-sensitive adhesive layer 4 protects (shown in Figure 1) usually.The utility model can be set as different colors according to the needs of unlike signal, and its breadth can be set as the cloth width of cloth shape of rolling usually.After making reflective literal, numeral, letter, symbol and sign sign, pictorial pattern, the adherent layer 3 that will be connected on the photocuring pressure-sensitive adhesive layer 4 is taken off, reflective membrane photocuring pressure-sensitive adhesive layer is directly glued together on the stickup object surfaces such as being connected in sheet metal caution label, cement road stake or reason stone buildings, by solar radiation photocuring pressure-sensitive adhesive layer 4, its rapid solidification and stickup object are connected.Can on photocuring pressure-sensitive adhesive layer 4 of the present utility model, not be connected with adherent layer 3 yet, directly be rolled into the band disk shape and use, as on cylindrical road stake cylindrical, directly being connected with the reflective membrane that different colours links to each other at interval around gummed.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not the technical characterictic that the process creative work just can be associated; can also make some modification or improvement; certainly; these variations all should be considered as equivalent feature, still belong within the scope of patent protection of the present utility model.
