Problems solved by technology

[0003] When dew condensation occurs on the reflective film, the tiny water droplets condensed on the surface of the reflective film will change the path of the incident light, reduce the incident light reaching the reflective layer, and when the incident light is reflected by the reflective layer to the surface of the reflective film, the fine water droplets The impact of refraction, so that the reflective effect of the reflective film is seriously weakened

Abstract

The invention provides a light reflecting film surface layer which serves as a surface layer of a light reflecting film. The surface layer comprises a base material, a plurality of light-transmitting protrusion structures are formed on a surface of the base material at a uniform interval, and the protrusion structures have flat top surfaces; a part, provided with no protrusion structure, of the surface of the base material is coated with a hydrophilic layer; the protrusion structures can be used for rapidly guiding water droplets to converge onto the hydrophilic layer and therefore protecting the hydrophilic layer from damage; the invention also provides the light reflecting film including the surface layer and manufacturing technologies therefor. Light reflecting performance of the light reflecting film surface layer and the light reflecting film cannot be affected by tiny water droplets, and a hydrophilic zone can be protected by the protrusion structures; an inorganic oxide coating on the hydrophilic zone can be prevented from being damaged or being stained by various kinds of grease when the light reflecting film is stored, transported, reprocessed and used; the light reflecting film is enabled to have a self protection function and permanently keep good dew-prevention and frost-prevention performance.

Description

technical field [0001] The invention relates to a surface layer of a reflective film, a reflective film and a manufacturing process thereof. Background technique [0002] Reflective film can reflect most of the incident light back in the direction of the emitted light source, and is widely used in a variety of products, such as road signs, obstacles blocking access, truck body identification, etc. Existing reflective films include glass beads There are two types of reflective film and micro-prism reflective film. The glass bead reflective film uses a lot of glass micro-beads to make a reflective layer with retroreflective effect. The micro-prism reflective film contains a transparent substrate layer and is arranged on the substrate layer. Micro-prism reflective layer with reflective effect. [0003] When dew condensation occurs on the reflective film, the tiny water droplets condensed on the surface of the reflective film will change the path of the incident light, reduce t...
