Problems solved by technology

[0005] However, the existing road surface reflective adhesive tape products, especially the road surface reflective adhesive tapes currently sold and used in large quantities in my country and other road surface lines, graphics, patterns, characters, symbols, raised road signs, There are still many shortcomings and deficiencies in various shapes of pavement reflective adhesive sheet products such as contour marks: mainly the optical properties, that is, the retroreflective (reflective) performance is not good enough and the wear resistance, mechanical strength and toughness are insufficient. Folds often crack and break
However, in this invention patent, we only briefly mentioned that these road surface reflective adhesive tapes can be used to make road traffic markings and other road traffic signs, but did not elaborate, and did not announce that they will be used to make road traffic signs in our country. Reflective adhesive sheets of other various shapes for the thirteenth road surface traffic markings (that is, other road surface lines, graphics, patterns, characters, symbols, raised road signs, contour marks and other road surface traffic signs) specified in the standard GB 5768.3-2009 Manufacturing method of the product

Embodiment 1

[0015] Example 1 Manufacture of road surface reflective adhesive tape products with composite rubber sheet as the base material, which has retroreflective properties and can emit fluorescence:

[0016] (1) Manufacture of composite rubber sheet base material: earlier 16.0 parts by weight of nitrile rubber, 4.0 parts by weight of polyester fiber, 5.0 parts by weight of polymer plasticizer (HXJZ-1), 20 parts by weight of white pigment titanium dioxide, 7.5 parts by weight of zinc oxide and 6.5 parts by weight of talcum powder (or 3.0 parts by weight of chrome yellow and 1.0 parts by weight of nickel titanate yellow pigment and filler), heated to 82 ° C in an internal mixer for 1 minute, and then added phenols 0.3 parts by weight of antioxidant, 13.0 parts by weight of chlorinated polyethylene and 0.3 parts by weight of stearic acid, continue heating and kneading for 3 minutes until the temperature reaches 100--120 ° C, and then transfer the kneaded material to an open mill , refi...

Embodiment 2

[0019] Example 2 Manufacture of road surface reflective adhesive tape products with composite rubber sheet as the base material, which only has retroreflective properties but no fluorescence:

[0020] Except that no fluorescent material is used in the manufacture of the reflective abrasive coating, the rest are implemented according to the exact same formula and manufacturing process as in (1), (2) and (3) of Example 1, and made into various specifications There are two white or yellow road reflective adhesive tape products, A and B, which only have retroreflective properties but cannot emit fluorescence. Its main performance is tested by the identical method of embodiment 1 (4). The observation test results are also listed in Table 1. These road reflective adhesive tape products were bent or even folded, and no obvious cracking and damage were observed.

Embodiment 3

[0021] Embodiment 3 The manufacture of road surface reflective adhesive sheet products of other various shapes (such as other road surface lines, graphics, patterns, characters, symbols, raised road signs, contour marks): All kinds of road surface reflective adhesive tape products compounded with release paper, according to the 13th type of reflective road traffic signs (that is, other road surface lines, graphics, patterns, characters, symbols, embossed, etc.) stipulated in the Chinese national standard GB 5768.3-2009 According to the shape design of road signs and contour marks) and the requirements of laser cutting machines, cut them into reflective adhesive sheets of a certain size; (2) Roll these reflective adhesive sheets flat and cut them into reflective adhesive sheets of corresponding shapes with laser cutting machines Adhesive products; (3) After cleaning and leveling the edges and dust, they can be classified and packaged.

Abstract

A reflective adhesive product used for road traffic markings and a manufacturing method thereof, comprising a composite rubber sheet substrate made by a calendering process, a reflective anti-slip coating and a pressure-sensitive adhesive layer and having retroreflection (i.e. reflective) Performance or various road reflective adhesive tape products that have retroreflective properties and can emit fluorescence, and other various shapes (such as other road lines, graphics, patterns, texts, etc.) that are further processed into these road reflective adhesive tape products There are two types of reflective adhesive sheet products for road surfaces, such as road signs, symbols, raised road signs, and contour marks. The road surface reflective adhesive tape product is not only tough and has good optical performance, but also the method of processing it into other various shapes of road surface reflective adhesive sheet products is also very simple: as long as the above road surface reflective adhesive tape product is made according to the shape According to the requirements of the design and laser cutting machine, it can be cut into a certain size of adhesive sheet, and then cut into a corresponding shape with a laser cutting machine to make it. These reflective adhesive products can be directly pasted or assembled and pasted on the treated road surface to make various road traffic markings.

Description

technical field [0001] The patent of the invention relates to a reflective adhesive product used for road traffic markings and a manufacturing method thereof, belonging to the technical field of road traffic and adhesive products. technical background [0002] Various road traffic markings (signs) are widely used on public roads such as highways, urban roads, public squares and parking lots to indicate and guide pedestrians and vehicles to pass in an orderly manner. my country's national standard GB 5768.3-2009 has clearly classified and stipulated various road traffic markings. Among the 13 different road traffic markings, the first 12 are about imaginary or solid road marking lines of various colors and shapes, and the thirteenth are about other road surface lines, graphics, patterns, characters, symbols, raised Road markings, outline markings and other road markings (see Table 1 of this standard). [0003] Among these road traffic markings, reflective road traffic marki...
