Problems solved by technology

The rising aluminum vapor during aluminizing by this method will continuously 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 grille being blocked The effect becomes worse, which leads to the boundary line between the aluminized area and the non-aluminized area on the reflective warning tape obtained in the later stage becomes very blurred, which affects the quality of the reflective warning tape
If the pressure-sensitive adhesive and the focusing layer on the plant film are bonded together to achieve the purpose of aluminum plating at intervals, but the bonding force between the pressure-sensitive adhesive and the focusing layer is high, it is easy to cause glass to appear during the subsequent peeling off of the pressure-sensitive tape. The microbeads fall off, affecting the appearance of the product

Abstract

The invention discloses a production method of a flame-retardant reflective warning tape. The method is characterized by comprising the following steps of 1, implantation of beads, wherein a PE layer I (1) in a PET-PE composite membrane I is heated and softened, then glass beads (2) are embedded in the PE layer I (1), the glass beads (2) are coated with an adhesive, and baking is carried out; 2, membrane covering at intervals, wherein PE layers II in a PET-PE composite membrane II after segmentation are heated and softened, and then the PE layers II are attached with equal distances to obtain spaced bead implantation membranes; 3, aluminizing, wherein the spaced bead implantation membranes in the second step are aluminized to obtain aluminized layers (4), and the PET-PE composite membrane II embedded in focusing layers (3) is peeled off; 4, recombination, wherein an adhesive layer of a pretreated base fabric and adhesive layers of pretreated spaced aluminized bead implantation membranes are recombined to form a flame-retardant adhesive layer (7), the PET-PE composite membrane I embedded on the surfaces of the glass beads (2) is peeled off, and the flame-retardant reflective warning tape is obtained. The production method of the flame-retardant reflective warning tape has the advantages of being simple in process, flat and smooth in touch and obvious in boundary.

Description

technical field [0001] The invention relates to the technical field of reflective materials, in particular to a method for making a flame-retardant reflective warning tape. Background technique [0002] Reflective warning tape is mainly used in the field of traffic safety, which plays the role of early warning. [0003] In the prior art, the preparation process of the flame-retardant reflective warning tape is more, and the product needs to go through a hot stamping process to attach the reflective layer to the flame-retardant base fabric, and the boundary between the reflective layer and the non-reflective layer of the prepared product has obvious heights Uneven, tactile feel, only the middle part has reflective function, no reflective effect on both sides. If the reflective tape is made by a bonding type winding vacuum aluminum coating machine, the high temperature resistant soft fabric barrier in the winding type vacuum aluminum coating machine is located between the bas...
