Problems solved by technology

[0003] In the prior art, it is conventional to stick various reflective stickers on the side walls of bicycle tires. The advantage of this method is that it is easy to replace and paste, but the defect exists: since the materials of the stickers are basically acrylic self-adhesive and The material of the tire is incompatible, cannot undergo vulcanization reaction, and the paste is not firm. In addition, the sticker is not stretchable, so when the tire itself shrinks due to pressure, the reflective sticker is easy to fall off

Embodiment 1

[0052] A vulcanizable reflective fabric for bicycle tires, comprising the following structural layers in sequence from inside to outside: vulcanizable polyurethane bonding layer, base fabric (TC cloth), modified vulcanizable polyurethane bonding layer, polyether modified polyurethane bonding layer layer, coated reflective layer, glass bead layer, hot melt layer and PET film.

[0053] The optional thickness of each layer is vulcanizable polyurethane bonding layer (40 filaments), base fabric, modified vulcanizable polyurethane bonding layer (25 filaments), polyether modified polyurethane bonding layer (15 filaments), coating reflective layer (1 filament), glass bead layer (5-10 filaments), hot melt layer (2-4 filaments), PET film (3.6 filaments).

[0054] The preparation method comprises the following steps:

[0055] (1) The hot-melt material is directly coated on the PET film to form a hot-melt layer;

[0056] (2) Sprinkle the glass beads evenly on the hot-melt layer, and bak...

Embodiment 2

[0075] The difference between this embodiment and embodiment 1 is:

[0076] In the present embodiment: the hot-melt layer that is coated on PET is EVA modified SIS hot-melt adhesive;

[0077] In the present embodiment: the metal film of plating is silver;

[0078] In the present embodiment: the ratio of polyether modified polyurethane and curing agent is 100:5;

[0079] In this embodiment: the ratio of vulcanizable polyurethane adhesive and reinforcing modifier on the TC cloth is 100:3;

[0080] In this example:

[0081] The ratio of vulcanizable polyurethane adhesive is as follows:

[0082] Polyester polyol (adipate-butanediol-6,6'-(1,4-xylylenedimethyl)dithio-1-hexanol ester) 75%, isocyanate (hexamethylene diisocyanate and Tetramethylxylylene diisocyanate mixture, wherein tetramethylxylylene diisocyanate content is 70%) 15%, sulfur-containing diol (bis[4-(3-hydroxypropyl)thiophenyl] thioether) 2%, without thiodiol (1,3 propylene glycol) 8%.

[0083] The molecular formu...

Embodiment 3

[0089] The difference between this embodiment and embodiment 1 is:

[0090] In this embodiment: the hot-melt layer coated on the PET is acrylic modified polyurethane resin.

[0091] In the present embodiment: the metal film of plating is silver;

[0092] In the present embodiment: the ratio of polyether modified polyurethane and curing agent is 100:3;

[0093] In this embodiment: the vulcanizable polyurethane adhesive on the TC cloth and the reinforcing modifier are 100:2;

[0094] In this example:

[0095] The ratio of vulcanizable polyurethane adhesive is as follows:

[0096] Polyester polyol (adipic acid-hexanediol-3,3'-(1,4-phenyldimethyl)dithio-1-propanol ester) 80%, isocyanate (isophorone diisocyanate and Tetramethylxylylene diisocyanate mixture, wherein tetramethylxylylene diisocyanate content is 60%) 10%, sulfur-containing dihydric alcohol (4,4'-(1,4-xylylene dimethyl) Dithio-1-butanol) 6%, no sulfur glycol (1,4-butanediol) 4%.

Abstract

The invention discloses a vulcanizable reflective cloth for bicycle tires, which comprises the following structural layers sequentially from the inside to the outside: a vulcanizable polyurethane bonding layer, a base fabric, a modified vulcanizable polyurethane bonding layer, and a polyether modified polyurethane bonding layer. layer, coated reflective layer, glass bead layer, hot melt layer and PET film. The invention has excellent adhesion to the rubber carrier, can be vulcanized at high temperature and high pressure simultaneously with rubber, has high bonding strength after vulcanization, good wear resistance, good riding resistance, and high surface brightness.

Description

technical field [0001] The invention relates to the technical field of reflective material production, in particular to a vulcanizable reflective cloth for bicycle tires. Background technique [0002] In consideration of safety, reflective materials are widely used in daily life, such as road traffic safety fields such as: temporary construction signs, road signs, anti-collision barrels, road cones, body reflective signs, etc.; reflective materials mainly include reflective film, Reflective cloth, reflective clothing, reflective hot stickers, reflective lattice, reflective leather, reflective pendants, reflective wrist straps, reflective pet straps, reflective arm straps, reflective calico and other products. At present, the country is paying more and more attention to the development of reflective materials. It is clearly required in European and American countries to paste reflective materials on bicycle tires. However, there is no clear decree on domestic bicycle tires. ...
