Problems solved by technology

Although the reflective cloth has good retroreflective performance by exposing the glass beads to the outside, in order to achieve the color effect, the glass beads are embedded on the colored resin layer, and the reflective cloth has a certain degree of reflection through light reflection. The color effect, the color is relatively fixed, can not meet the demand for color or pattern in the later stage, so that the reflective cloth cannot be given more color, photo or pattern effect, and it is impossible to use inkjet painting and other methods to give the reflective film more effects in the later stage. Aesthetics means no printability

Abstract

The invention relates to a thermosensitive type light reflection film capable of being jet printed, and belongs to the technical field of reflecting materials. The existing problem that high retro-reflecting coefficient and jet printing can not be achieved simultaneously is solved, the light refection film comprises a thermosensitive adhesive layer and a resin layer which are overlapped in sequence from top to bottom and fixed, multiple grooves are formed in the upper portion of the resin layer, each groove is internally embedded with a glass bead, a reflecting layer is laid between a groove wall of each groove and the corresponding glass bead, coatings capable of being jet printed are arranged on the upper surface of the resin layer, and the upper portion of each glass bead is higher than the corresponding coating capable of being jet printed. The thermosensitive type light reflection film capable of being jet printed has a better jet printing effect, and the double-effect of higher retro-reflecting coefficient is achieved. The coatings capable of being jet printed between each two glass beads are designed to be shaped like a sunken arc surface, so that the effect that the retro-reflecting coefficient is greater than 400 cd.lx<-1>.m<-2> is achieved.

Description

technical field [0001] The invention relates to a spray-paintable heat-sensitive reflective film, which belongs to the technical field of reflective materials. Background technique [0002] With the development of the national economy, my country's transportation system is becoming more and more developed, and the subsequent traffic management and traffic safety have been mentioned in a very important position. Strengthen traffic management, ensure traffic safety, and ensure the implementation of the "smooth traffic project". To ensure the development of the national economy. The addition of traffic signs, road traffic safety facilities, vehicle signs and indicator signs made of reflective film materials with retro-reflective properties is an important part of traffic safety management. Various reflective film materials have played an important role in the field of traffic safety. important role. However, because the conventional reflective film can no longer meet the needs...
