Description

Technical Field

[0001] The utility model relates to a reflective film, in particular to a waterproof and anti-fouling reflective film. Background Art

[0002] Reflective film is a kind of reflective material made by the high refraction principle of glass beads or microprisms, mainly used for traffic warning signs, warning clothing, etc.; the existing reflective film is generally directly exposed to the air when used. Once it rains, water droplets from the outside will stay and adhere to the surface of the reflective film. In addition, because rain usually contains dust in the air, these dust will also stay on the surface of the reflective film with the rain, thus affecting the reflective effect of the entire reflective film. Therefore, the existing reflective film has the problem of poor reflective effect on rainy days. Utility Model Content

[0003] The purpose of the utility model is to provide a waterproof and anti-fouling reflective film. The utility model has the advantage of good reflective effect on rainy days.

[0004] The technical solution of the utility model is as follows: a waterproof and antifouling reflective film comprises a glass micro-bead reflective layer, a plurality of evenly distributed convex strips are arranged on the top surface of the glass micro-bead reflective layer, and the top surface of each convex strip is in an arc shape; a hydrophobic layer is bonded to the top surface of each convex strip, a grid layer is bonded between the bottom surfaces of all the convex strips, and the bottom surface of the grid layer is bonded to the glass micro-bead reflective layer; by arranging a plurality of evenly distributed convex strips on the top surface of the glass micro-bead reflective layer, and the top surface of each convex strip is in an arc shape, and cooperating with the hydrophobic layer arranged on the top surface of the convex strip, when the external environment When fog, rain or dust in the environment falls on the reflective film, it will automatically flow between the two convex strips under the hydrophobic effect of the hydrophobic layer and the guiding effect of the arc-shaped convex surface of the convex strip, and the rain will not stay on the reflective film to cause obstruction, which ensures the waterproof and anti-fouling effect of the reflective film and improves the reflective effect of the reflective film on rainy days. Using a grid layer to connect the glass bead reflective layer and the convex strips can increase the friction points between the glass bead reflective layer and the convex strips, avoid slipping in the connection, and improve the stability of the structure.

[0005] In the aforementioned waterproof and antifouling reflective film, an antifouling strip is bonded between each two adjacent convex strips; the antifouling strip can prevent the remaining liquid or dust from entering between the convex strip and the glass microbead reflective layer, further improving the waterproof and antifouling effect of the reflective film.

[0006] In the aforementioned waterproof and anti-fouling reflective film, the glass bead reflective layer includes a base layer, and an upper reinforcing layer and a lower reinforcing layer are respectively bonded to the upper and lower sides of the base layer; a wear-resistant layer is bonded to the top surface of the upper reinforcing layer, and a plurality of evenly distributed glass beads are arranged between the wear-resistant layer and the upper reinforcing layer; the upper reinforcing layer and the lower reinforcing layer can be used to improve the tensile strength of the base layer on the upper and lower sides of the base layer, thereby improving the tear resistance of the entire glass bead reflective layer; the transparent wear-resistant layer can be used to provide wear-resistant protection for the glass beads without affecting the refraction and reflection of the glass beads, thereby extending the service life.

[0007] In the aforementioned waterproof and antifouling reflective film, the upper reinforcement layer and the lower reinforcement layer are both honeycomb structures.

[0008] In the aforementioned waterproof and anti-fouling reflective film, the convex strips are made of transparent glass material; by setting the convex strips to be made of glass material, light can be gathered to a certain extent at the convex strip positions, further improving the reflective effect.

[0009] Compared with the prior art, the utility model improves the existing reflective film by arranging a plurality of evenly distributed convex strips on the top surface of the glass microbead reflective layer, the top surface of each convex strip is in an arc shape, and cooperates with the hydrophobic layer arranged on the top surface of the convex strip, so that when fog, rain or dust in the external environment falls on the reflective film, it will automatically flow to between the two convex strips and flow out under the hydrophobic effect of the hydrophobic layer and the guiding effect of the arc-shaped convex surface of the convex strip, and the phenomenon of rainwater staying on the reflective film to cause shielding will not occur, thereby ensuring the waterproof and anti-fouling effect of the reflective film and improving the reflective effect of the reflective film on rainy days. At the same time, by bonding a grid layer between the bottom surfaces of all the convex strips and using the grid layer to connect the glass microbead reflective layer and the convex strips, the friction points of the connection between the glass microbead reflective layer and the convex strips can be increased, the phenomenon of connection slippage can be avoided, and the stability of the structure can be improved. In addition, the present invention further improves the waterproof and anti-fouling effect of the reflective film by bonding an anti-fouling strip between each two adjacent convex strips, and the anti-fouling strip can prevent the remaining liquid or dust from entering between the convex strips and the glass micro-bead reflective layer; by arranging the glass micro-bead reflective layer to be composed of a lower reinforcing layer, a base layer and an upper reinforcing layer, the upper reinforcing layer and the lower reinforcing layer can improve the tensile strength of the base layer on both sides of the base layer, thereby improving the tear resistance of the entire glass micro-bead reflective layer; by bonding a wear-resistant layer on the top surface of the upper reinforcing layer, a wear-resistant layer is provided between the wear-resistant layer and the upper reinforcing layer Glass beads are arranged, and a transparent wear-resistant layer is used to protect the glass beads from wear without affecting the refraction and reflection of the glass beads, thereby extending the service life; by setting the upper reinforcement layer and the lower reinforcement layer into a mesh structure, while ensuring the anti-lass ability, the grid on the upper reinforcement layer can also limit the position of the glass beads to a certain extent, avoiding the stacking of the glass beads during the subsequent washing or rubbing process, thereby ensuring the reflective effect; by setting the convex strips to be glass material, the light can also be gathered to a certain extent at the convex strip position, further improving the reflective effect. Therefore, the utility model can not only improve the reflective effect of the reflective film on rainy days, but also has the advantages of high structural stability, good waterproof and anti-fouling effect, high tear resistance, good reflective effect and long service life.

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] Embodiment. A waterproof and antifouling reflective film, comprising: Figures 1 to 3 As shown, it includes a glass bead reflective layer 1, on the top surface of which a plurality of evenly distributed convex strips 2 are arranged, and the top surface of each convex strip 2 is in an arc shape; a hydrophobic layer 3 is bonded to the top surface of each convex strip 2, and a grid layer 4 is bonded between the bottom surfaces of all the convex strips 2, and the bottom surface of the grid layer 4 is bonded to the glass bead reflective layer 1.

[0016] An anti-fouling strip 5 is bonded between every two adjacent convex strips 2; the glass bead reflective layer 1 includes a base layer 6, and an upper reinforcing layer 7 and a lower reinforcing layer 8 are bonded to the upper and lower sides of the base layer 6 respectively; a wear-resistant layer 9 is bonded to the top surface of the upper reinforcing layer 7, and a plurality of evenly distributed glass beads 10 are arranged between the wear-resistant layer 9 and the upper reinforcing layer 7; the upper reinforcing layer 7 and the lower reinforcing layer 8 are both honeycomb structures; the convex strips 2 are made of transparent glass material.

[0017] Working principle: When rain drops from the outside on the surface of the entire reflective film, first, the rain will contact the hydrophobic layer 3 of the outermost layer of the reflective film. Because of the hydrophobic property of the hydrophobic layer 3, the rain can be prevented from adhering to the reflective film, that is, the rain can flow on the hydrophobic layer 3; at this time, because the top surface of the convex strip 2 is a convex arc shape, the flowing rain can automatically flow between the two convex strips 2 under the action of its own gravity and the top surface of the convex strip 2. Because an anti-fouling strip 5 is provided between the two convex strips 2, the anti-fouling strip 5 can be used to prevent rain from entering the glass microbead reflective layer 1, and the rain will flow out along the anti-fouling strip 5, thereby avoiding the reflective film. Because the reflective effect is weakened due to the adhesion of rainwater to the surface, the reflective effect of the reflective film on rainy days is improved; at the same time, because the glass reflective layer is composed of the lower reinforcing layer 8, the base layer 6 and the upper reinforcing layer 7, the lower reinforcing layer 8 and the upper reinforcing layer 7 can increase the tensile and tearing resistance of the entire base layer 6, thereby improving the structural strength of the entire glass bead reflective layer 1; the provision of the wear-resistant layer 9 can protect the glass beads 10, reduce the wear of the glass beads 10, and extend the service life; the provision of the grid layer 4 can increase the contact and friction area between the convex strips 2 and the glass bead reflective layer 1, thereby improving the strength of the connection between the two and improving the structural stability of the entire reflective film.
