Description
Technical Field
The invention relates to the technical field of labels, in particular to an IPC C08L75, and more particularly relates to a welt label and a preparation method thereof.
Background
In daily life, products prepared from resin materials, such as bags, toys, building materials and the like, can be frequently seen, and people's lives are interspersed.
The prior patent CN201811358447.0 discloses a composite membrane formed by blending antibacterial TPU and PVC and a preparation method thereof, wherein the TPU and the PVC are mixed and then are mixed, and the obtained mixture in a molten state is heated and plasticized until the mixture is completely and fully plasticized; finally, filtering the fully plasticized mixture, removing impurities and the like; the composite membrane blended by the antibacterial TPU and the PVC with better sterilization and disinfection and longer service life is obtained. However, the toughness and the color fixing effect of the mixture are still questionable.
At present, most young people have various pursuits on shoes, but the market of the labels of the shoes on the market is smaller, and the common labels are formed by PVC (polyvinyl chloride) materials alone, so that the labels have poor toughness and ductility, are easy to crack and break, have shorter service life and poor fixation property on colors, and meanwhile, the dependence of the current young people on washing machines is increasingly increased. Therefore, there is a need to develop a welt label that has good color fixing ability, strong toughness, is not easy to crack, and is not easy to be damaged by a washing machine.

s2: placing the first layer of glue in the upper layer of the mould 2, uniformly mixing resin, plasticizer and toner into a liquid state, introducing the liquid state into the lower layer of the mould 2, combining the mould 2 into a whole, placing the mould into the temperature of 350-400 ℃ for 40-60 s, and cooling for 10-30 s to form a bonding layer;
s3: spraying resin glue on the bottom surface layer of the bonding layer;
s4: placing the attaching layer into a mold, and enabling the bottom surface layer and the polyurethane rubber mixed with the toner to be molded into a whole to obtain the welt label.
Preferably, the resin in the step S1 is a natural resin or a synthetic resin.

Preferably, the plasticizer in the step S1 comprises one or more of DOTP plasticizer, ATBC plasticizer, TOTM plasticizer, DPHP plasticizer; further preferred is DOTP (dioctyl terephthalate) plasticizer.
Preferably, the weight ratio of the resin to the plasticizer in the step S1 is (0.5-1.5): 1, a step of; further preferably, (0.9 to 1.1): 1.
preferably, in the step S1, the weight ratio of the resin to the toner is 50: (1-10); further preferably, 50: (1-5).
Preferably, the resin in the step S2 includes one or more of PE resin, PVC resin, PS resin, PP resin, ABS resin; further preferably, the resin is a PVC resin.

Preferably, the weight ratio of the resin to the plasticizer in the step S2 is (0.5-1.5): 1, a step of; further preferably, (0.9 to 1.1): 1.
in the invention, the weight ratio of the resin to the plasticizer is controlled to be (0.9-1.1): 1, the toughness and the friction resistance of the first layer and the second layer of the adhesive tape are improved, and the dry friction color fastness of the first layer and the second layer of the adhesive tape is also improved. The inventors creatively found that the weight ratio of PVC resin to DOTP plasticizer was controlled to be (0.9-1.1): 1, not only can the toughness of the adhesive plaster be improved, but also the deformation resistance of the adhesive plaster can be improved. The toughness of the adhesive tape can be reduced by adding excessive PVC resin, and the adhesive tape can be broken and damaged in high-speed rotation in the process of washing with water by a washing machine. The PVC resin is added too little, so that the formed adhesive tape is too soft and is easy to deform, deform in use and be easily damaged by friction. On the other hand, the weight ratio of the PVC resin to the DOTP plasticizer is controlled to be (0.9-1.1): 1, the color fixation of the toner in the adhesive tape can be better carried out, and the vivid color can be kept.
Preferably, the resin adhesive in the step S3 is a hot melt adhesive.
Preferably, the resin glue is a southern light resin glue.

According to the invention, a layer of southern light resin adhesive is sprayed between the attaching layer and the polyurethane rubber, so that the viscosity between the attaching layer and the polyurethane rubber material is improved, and the overall firmness and the service life of the welt label are improved. The inventor speculates that after a layer of southern light resin adhesive is sprayed on the attaching layer, the high Wen Shina light resin adhesive and the TPU are in a liquid state in the injection molding process, molecular chains of the two materials are intersected at a liquid interface, and the adhesive property of the PVC resin and the TPU resin is improved, so that the integral firmness of the welt label is improved, and the welt label is prevented from being easily damaged by being treaded on shoes.
Preferably, the polyurethane rubber in the step S4 includes one of a mixed polyurethane elastomer, a cast polyurethane elastomer and a thermoplastic polyurethane elastomer; further preferred are thermoplastic polyurethane elastomers.
Preferably, the polyurethane rubber in the step S4 is TPU.
Preferably, the TPU is TPU (95A).
Preferably, the TPU (95A) is available from Kunshan hundred Lin Wang New plastic materials Co., ltd. Model 17195A.

Preferably, the collar is arranged on the bottom surface layer, which is not contacted with the attaching layer, of the welt label, and the collar is fixedly connected with the bottom surface layer, and is realized by injection molding.
In the invention, the shoelace can be threaded through the rings and then tied, so that the welt label is fixed on the shoelace, and the aesthetic property and the artistic property of the shoe body are improved.
In the invention, different PVC resins are injected into film layers with certain patterns by adding a certain proportion of plasticizer, then the film layers with certain patterns, the lower resin, the plasticizer and the toner mixed liquid are combined together, and the combined film layers are placed in a temperature of 350-400 ℃ for 40-60 s, and cooled for 10-30 s, so that a bonding layer which meets the standard and contains two layers of PVC resins can be obtained. The inventors have unexpectedly found that controlling the temperature and time is critical to the formation of the conforming layer. The temperature is too low, the time is too short, when the die is placed in the environment, the actual temperature in the die cannot reach the required temperature, the lower layer PVC resin cannot be completely melted, the color is unevenly mixed, and the lower layer PVC resin and the upper layer PVC resin cannot be firmly combined together. When the temperature is too high, the time is too long, the actual temperature in the die is too high, so that the part of the first layer of adhesive tape is melted, the patterns of the first layer of adhesive tape become paste, the appearance of the attached layer is affected, the product quality is further reduced, the number of unqualified products is increased, and the cost is increased.
The second aspect of the invention provides a welt label prepared by the preparation method of the welt label.
The third aspect of the invention provides an application of the welt label prepared by the preparation method of the welt label to shoes.
