Manufacturing method of light-reflecting warning tape

Abstract

The invention discloses a manufacturing method of a light-reflecting warning tape. The method comprises the following steps of a, discontinuously jointing an adhesive tape on a glass microbead surface of a light-reflecting planting bead film, wherein the adhesive tape comprises a PET layer and a pressure-sensitive adhesive layer; the pressure-sensitive adhesive layer is composed of a silicone pressure-sensitive adhesive and a curing agent and a proportion is 100:0.1-100:1.2; a proportion of a thickness of the pressure-sensitive adhesive layer and a grain size of the glass microbeads on the light-reflecting planting bead film is 2:1-3:1; b, carrying out vacuum aluminizing so as to form an aluminizing film; c, peeling the adhesive tape on the aluminizing film so as to form a clear boundary of aluminizing and non-aluminizing interfaces and acquiring a discontinuous aluminizing planting bead film; d, coating resin containing a fluorescent pigment on an aluminizing surface of the discontinuous aluminizing planting bead film, and after being dried through a 50DEG C-120 DEG C oven, compositing with a fabric base to form a light-reflecting warning tape. By using the manufacturing method of the light-reflecting warning tape, after long time use, the boundary of the aluminizing and non-aluminizing interfaces on the finally-obtained light-reflecting warning tape can be guaranteed to be clear.

Description

technical field [0001] The invention relates to a reflective warning tape, in particular to a production method of the reflective warning tape. Background technique [0002] Reflective warning tape is mainly used in the field of traffic safety, which can play an early warning role for pedestrians and drivers. When the existing reflective warning tape is made, especially in the aluminum plating process, it is generally carried out aluminum plating by means of cloth strips. For example, the announcement date is May 6, 2015, the announcement number is CN103088291B, and the name is "sticker". The patent for the invention of "Fitted Winding Vacuum Aluminum Coating Machine and Manufacturing Method of Reflective Warning Tape" discloses a method for making reflective warning tapes using a fitted winding vacuum aluminum coating machine. To make a reflective tape, the high-temperature-resistant flexible fabric barrier is located between the substrate and the evaporation boat in the w...

AI Technical Summary

Problems solved by technology

The reason is that on the one hand, when the high temperature resistant flexible fabric grid is used for shielding, because the glass beads on the substrate are spherical, the spherical glass on the substrate will be in the process of passing through the evaporation boat. The microbeads will produce sliding friction with the high-temperature-resistant flexible fabric grille, which not only affects the quality of the glass beads, but also causes the surface of the high-temperature-resistant soft fabric grille to wear after long-term use and cannot be tightly attached to the surface of the substrate ; on the other hand, after long-term use, rising aluminum vapor will continue to deposit on the high-temperature-resistant soft fabric grille, making the grille less flexible and gradually becoming rigid, unable to fit the substrate tightly, resulting in The blocking effect of the grille becomes worse, which leads to the blurring of the boundary line between the aluminized area and the non-aluminized area on the reflective warning tape obtained later, which affects the quality of the reflective warning tape
