Embodiment 1

[0025] like figure 1 As shown, the reflective film of the present invention is composed of a reflective film layer 1 , a glass bead layer 2 , a focusing resin layer 3 , a metal reflective layer 4 , a pressure-sensitive adhesive layer 5 and an anti-sticking paper layer 6 .

[0026] The specific production process of the present invention is: the glass microspheres of 300-350 mesh refractive index 1.90 are first pickled with oxalic acid, then add 5% silane coupling agent of glass microsphere weight after drying, add glass microsphere weight 1% sodium dodecyl sulfonate, stir and mix evenly, and dry completely, so that the microbeads and resin have better compatibility, play a role in wetting and reducing surface tension. The reflective film layer 1 is made of BOPET (biaxially oriented polyester) material, which has good transparency, a light transmittance of 90%, and a thickness of 50 μm. Mix 2 parts of glass microspheres treated with surface organic modification with 3 parts of...

Embodiment 2

[0028] The specific production process of the present invention is: the glass microspheres of 450-500 mesh refractive index 1.93 are pickled with tartaric acid first, then add 5% silane coupling agent after drying, 1% sodium dodecylsulfonate, Stir to combine and dry completely. Wherein the reflective film layer 1 is made of BOPET material with a thickness of 52 μm. 2 three parts of glass microspheres treated with surface organic modification and 35 parts of acrylic acid polymerization modified focusing layer resin are stirred evenly at high speed, the stirring speed is 3000-3500 rpm, and the stirring time is 18 minutes; the acrylic acid polymerization modified The solid content of the resin in the focusing layer is controlled at 27%, the viscosity is controlled at 170cP, and 0.5% of silicone oil defoaming and leveling agent is added to the resin. Apply the above mixed material glue on the reflective surface layer 1, the thickness of the wet glue layer is controlled to 180μm-2...

Abstract

The invention relates to a preparation method for a glass micro-bead sedimentation type light-reflective membrane. The preparation method comprises a first step of making a light-reflective mask layer and a second step of making a light-reflective layer. The second step is of mixing the glass micro-bead and the acrylic acid polymerized modified focusing layer resin in certain proportion and stirring evenly with high speed, coating the mixed resin material on the light-reflective mask layer, and the thickness is greater than the diameter of the glass micro-bead, then roasting and drying at the temperature between 50 DEG C and 130 DEG C inside a drying tunnel. The third step is the vacuum evaporation of a metal reflecting layer and compositing with a stained paper layer which is coated with a pressure-sensitive adhesive layer. The preparation method for the glass micro-bead sedimentation type light-reflective membrane has the advantages of being simple and practical in technology, capable of reducing the production cost and improving the production efficiency and the rate of the end product..

Description

technical field [0001] The invention relates to a microbead-type optical material, specifically a reflective film formed by coating a glass microsphere and a resin mixed material at one time. Background technique [0002] Micro-bead type reflective film is mainly divided into two categories according to the structure, one is the lens embedded type, and the other is the sealed capsule type; according to the application, it is mainly divided into several types such as advertising grade, engineering grade, license plate grade, and high-strength grade. Advertising-grade reflective film is mainly used for the production of billboards and related products, engineering-grade reflective film is mainly used for the production of traffic signs on grade highways and urban roads, license plate-grade reflective film is mainly used for the production of motor vehicle license plates, and high-strength reflective film is mainly used It is used in the production of permanent traffic signs an...
