Problems solved by technology

[0004]With the expansion of people's application of reflective materials, reflective materials have been gradually applied to uniforms, work clothes and protective clothing, etc. With the increase of requirements, the general reflective cloth can only withstand ordinary 60 ℃ water washing (ie ISO 6330 2A procedure) 100 times, but it cannot reach 25 times of industrial washing

preparation example Construction

[0039] A preparation process of heavy-industrial washing-resistant reflective cloth, the preparation process steps are as follows:

[0040] (1) Put the PE / PET composite film in the plant heating roller, the heating roller rotation speed is 1-30m / min, the temperature is controlled between 130-210℃, as the PE film melts, the glass beads settle on the PE On the film, after the PE film is cooled, the glass beads are fixed on the PE film, thereby realizing the implantation of glass beads to obtain a glass bead layer, thereby obtaining a semi-finished product with a PE / PET composite film and a glass bead layer;

[0041] (2) The glue prepared by solvent, resin, curing agent and auxiliary agent is evenly coated on the surface of the glass beads described in step (1) to form a spherical focusing layer concentric with the glass beads, and then baked through a drying tunnel Dry solvent film formation, thereby obtaining a semi-finished product with PE / PET composite film, glass bead layer and p...

Embodiment 1

[0048] The raw material ratio of the protective composite rubber in step (5) is: 60 parts of main resin, 1 part of curing agent, 1 part of auxiliary agent, and 30 parts of diluent; the ratio of raw materials of composite rubber in step (6) is: 60 parts of main resin , 10 parts of flame retardant, 1 part of curing agent, 1 part of auxiliary agent, 30 parts of diluent, 2 parts of pigments and fillers. The main resin is solvent-based acrylic resin, the curing agent is isocyanate curing agent, the auxiliary is lubricant, diluting The agent is ethyl acetate, the flame retardant is a phosphorus flame retardant, and the pigment and filler are aluminum powder or aluminum paste.

[0049] The base fabric is chemical fiber cloth; the thickness of the composite adhesive layer is 25um; the thickness of the composite adhesive protective layer is 250um; the inert material layer is a silicon dioxide layer with a thickness of 10nm; the metal plating layer is a metal aluminum plating layer with a t...

Embodiment 2

[0052] The raw material ratio of the protective composite rubber in step (5) is: 60 parts of main resin, 7 parts of curing agent, 1 part of auxiliary agent, and 20 parts of diluent; the ratio of raw materials of composite rubber in step (6) is: 60 parts of main resin , 5 parts of flame retardant, 8 parts of curing agent, 1 part of auxiliary agent, 10 parts of diluent, 3 parts of pigments and fillers. The main resin is solvent acrylic resin, the curing agent is aziridine curing agent, and the auxiliary is dispersing agent. , The diluent is toluene, the flame retardant is nitrogen-based flame retardant, and the filler is toner or color paste.

[0053] The base fabric is TC cloth; the thickness of the composite adhesive layer is 50um; the thickness of the composite adhesive protective layer is 500um; the inert material layer is a silicon dioxide layer with a thickness of 100nm; the metal coating is a metal aluminum coating with a thickness of 0.1nm; focusing layer The thickness is 5...

Abstract

The invention relates to a reflective fabric and in particular relates to a preparation process of a reflective fabric with the heavy industry washing fastness. The reflective fabric comprises a base cloth, a complex adhesive layer, a complex adhesive protection layer, an inert substance layer, a metal coating layer, a focusing layer, a glass microballoon layer and a transparent protection layer, wherein the complex adhesive layer is arranged on the base cloth; the complex adhesive protection layer is arranged on the complex adhesive layer; the inert substance layer is arranged on the complex adhesive protection layer; the metal coating layer is arranged on the inert substance layer; the focusing layer is arranged on the metal coating layer; the glass microballoon layer is arranged on the focusing layer; the transparent protection layer is arranged on the glass microballoon layer. The reflective fabric has the firm and washable cloth base; regression reflective glass microballoons are attached onto all durable fabric lining cushions; the washing fastness is improved; the reflective intensity is high; the reflective intensity typical value reaches more than 420CPL; when the reflective fabric is sewed onto other fabrics and linings, the reflective fabric has an extremely obvious effect of improving the visibility of wearers in night or in the environment with the bad visibility.

Description

technical field [0001] The invention relates to the field of reflective cloth preparation, in particular to a preparation process of heavy industrial washable reflective cloth. Background technique [0002] Reflective materials are mainly used to make various reflective signs, vehicle license plates, safety facilities, etc. During the day, their bright colors play an obvious warning role, and at night or when the light is insufficient, the bright reflective effect can effectively enhance people's The ability to recognize, see the target clearly, and cause vigilance, thereby avoiding accidents, reducing casualties, reducing economic losses, and becoming an indispensable safety guard for road traffic has obvious social benefits. The scope of use is widely involved in public security transportation, traffic supervision, fire protection, railways, coal mines, oil fields and other departments and fields. Civilian reflective materials are mainly reflective cloth, reflective lattic...
