Problems solved by technology

The method of coating the waterproof layer first affects the performance of the product such as washing resistance and wear resistance, and the retroreflection coefficient of the reflective cloth is not mentioned
[0014] A manufacturing method of a retro-reflective coating and the obtained coating described in the Chinese Patent Authorization Publication No. CN1281012A, in which glass beads with a refractive index N of about 1.9 are applied, and the obtained retro-reflective coating is processed on the surface of an object by using a transfer method process route The retroreflection coefficient of the product is only 100~180cd / lx / m 2 , suitable for making retroreflective signs such as enlarged characters and / or patterns, the transfer substrate used in this patent is a self-adhesive film, and a coating composition containing different pigments is used as a coating to adhere to glass beads; But at present, the retroreflection coefficient of this product (100~180cd / lx / m 2 ) has gradually been unable to meet the high-brightness requirements of the current reflective fabrics, and the product cannot be ironed onto clothing

Embodiment 1

[0059] At 120°C, the glass beads with a refractive index of 1.90 and a diameter of 70 microns are adhered to the surface of the polyethylene film transfer substrate by the adhesion coating method to make about 45% of the glass beads with a diameter of 70 microns. The surface contains 100 grams of glass beads;

[0060] Then, on the protruding surface of the glass beads, use vacuum aluminum plating equipment to vacuum metal aluminum to form a metal reflective layer with a thickness of 0.06 μm;

[0061] Then, the solvent is toluene, and the polyurethane solution containing 20% ​​by weight is coated on the metal reflective layer, and a dry coating is adopted to form an adhesive layer;

[0062] Then use 0.3MPa pressure to compound the polyester-cotton base material on the laminating machine, dry it at 100°C, and finally peel off the transferred base material at a constant speed with a stripping machine at room temperature to obtain a retro-reflective fabric.

[0063] The retro-ref...

Embodiment 2

[0065] At 130°C, the glass beads with a refractive index of 1.91 and a diameter of 65 microns are adhered to the surface of the polypropylene film transfer substrate by the waterfall method to make 52% of the diameter of the glass beads, and reach the surface of the film per square meter Contains 120 grams of glass beads;

[0066] After natural cooling, on the protruding surface of the glass beads, use vacuum aluminum plating equipment to vacuum metal aluminum to form a metal reflective layer with a thickness of 0.09 μm;

[0067]Then water is used as solvent, and the self-crosslinking type methyl acrylate solution containing 35% by weight is coated on the metal reflective layer, adopts dry coating, and then uses 0.4MPa pressure on the composite machine to composite the nylon spinning base material, at 100 Dry at ℃, peel off at a constant speed at room temperature with a peeling machine, remove the transfer substrate, and obtain a retro-reflective fabric;

[0068] In order to ...

Embodiment 3

[0071] At 110°C, glass beads with a refractive index of 1.90 and a diameter of 90 microns are adhered to the surface of polyethylene composite paper by electrostatic adsorption method to make 30% of the glass beads with a diameter of 110 microns per square meter of film surface. grams of glass beads;

[0072] Then, on the protruding surface of the glass beads, the vacuum evaporation equipment is used to vacuum-plate metal aluminum and titanium to form a metal reflective layer with a thickness of 0.03 μm;

[0073] Then water is a solvent, and the rubber aqueous emulsion of 25% by weight is coated on the metal reflective layer; on this basis, it is coated with a polyester solution of 18% by weight with toluene and butanone as a solvent, and then Composite polyurethane substrate with 0.35MPa pressure on the compound machine, dry at 110°C, peel off at 80°C with a peeling machine, remove the transfer substrate, and obtain a retroreflective fabric. The retroreflective fabric prepare...

Abstract

This invention discloses a kind of regression reflect fabric, including one reflection component, a metal reflection layer, a adhesive layer and one basic material, the reflection component layer is implied 30-130 grams of tiny glass beads with each square arranged intensively. The fabric's reflection function is good, the anti-coefficient can amount to the 70-700 cds / Lx / square m.

Description

technical field [0001] The invention relates to a reflective fabric and a production method thereof, in particular to a retroreflective fabric and a production method thereof. Background technique [0002] Retroreflective fabrics have the special function of reflecting incident light back to the light source along the incident direction. It is very eye-catching when there is a light source at night, making it safe for people traveling and active at night to carry this material, so retroreflective fabrics are widely used at night Or on the work clothes of the staff in the dark, the observer can find the target at a distance, and take timely measures to reduce accidents. [0003] An early and widely used retroreflective material was in the form of bead embedding, initially described in U.S. Patent No. 2,407,680. This material consisted of a transparent polyester layer, a monolayer of microbeads embedded in it, and A special reflective layer on the surface of the polyester lay...
