Embodiment 1

[0047] The TPU hot melt adhesive provided in the present embodiment is attached to a TPU foam film, which includes a TPU hot melt adhesive and a TPU foam film layer 1, and also includes a TPU located on the surface of the TPU hot melt adhesive and a TPU foam film layer 1. Hot melt adhesive layer 2. Wherein, by weight percentage, TPU foam film comprises the following components:

[0048] Polyester thermoplastic polyurethane particles 80%;

[0049] Foaming agent sodium bicarbonate 10%;

[0050] Slip agent silicone oil 4%;

[0051] Antioxidant Tetrakis[methylene-3,3',5-(di-tert-butyl-4-hydroxy-phenyl)propionate]pentaerythritol ester 0.5%;

[0052] Benzoic acid anti-ultraviolet agent 1.5%;

[0053] Masterbatch 4%.

[0054] Among them, polyester thermoplastic polyurethane is prepared from polyester polyol, 4,4'-diphenylmethane diisocyanate (MDI) and 1,4-butanediol as raw materials.

Embodiment 2

[0056] The difference with embodiment 1 is:

[0057] By weight percentage, TPU foam film includes the following components:

[0058] Polyether thermoplastic polyurethane particles 88%;

[0059] Foaming agent azodicarbonamide 3%;

[0060] Slip agent methyl silicone oil 2%;

[0061] Antioxidant N,N'-bis[[3-(3,5)-di-tert-butyl-4-hydroxyphenyl]propionyl]hexamethylenediamine 0.3%;

[0062] Xylene ketone anti-ultraviolet agent 1.7%;

[0063] Masterbatch 5%.

[0064] Among them, polyether thermoplastic polyurethane is prepared from polytetrahydrofuran, toluene diisocyanate (TDI) and 1,4-butanediol as raw materials.

[0065] The rest are the same as in Embodiment 1, and will not be repeated here.

Embodiment 3

[0067] The difference with embodiment 1 is:

[0068] By weight percentage, TPU foam film includes the following components:

[0069] Polyester thermoplastic polyurethane particles 63%;

[0070] Blowing agent sodium lauryl sulfate 22%;

[0071] Slip agent water-soluble silicone oil 5%;

[0072] Antioxidant tris[2,4-di-tert-butylphenyl]phosphite 0.7%;

[0073] Benzotriazole anti-ultraviolet agent 1.3%;

[0074] Masterbatch 8%.

[0075] Among them, polyether thermoplastic polyurethane is prepared from polytetrahydrofuran, toluene diisocyanate (TDI) and 1,4-butanediol as raw materials.

[0076] The rest are the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention belongs to the technical field of a foamed product, in particular to TPU (thermoplastic polyurethane) hot-melt-adhesive laminated TPU foamed film. The TPU hot-melt-adhesive laminated TPU foamed film comprises a TPU hot-melt-adhesive laminated TPU foamed film layer and also comprises a TPU hot-melt-adhesive layer which is arranged on the surface of the TPU hot-melt-adhesive laminated TPU foamed film layer. Compared with the prior art, the invention has the advantage that the hot-melt-adhesive layer is compounded on the surface of the TPU hot-melt-adhesive laminated TPU foamed film layer to obtain the TPU hot-melt-adhesive laminated TPU foamed film which has good physical performance and can completely substitute a soft PVC (polyvinyl chloride) foamed plastic film in the automobile industry field. The TPU hot-melt-adhesive laminated TPU foamed film not only has good adhesive property, but also is environment-friendly and can be greatly recycled, and no substance which is harmful to the health and the environment is produced when the TPU hot-melt-adhesive laminated TPU foamed film is burned under a possible situation. In addition, the TPU hot-melt-adhesive layer is strong in adhesive force and wide in applicable temperature range, has good heat resistance, cold resistance, acid resistance, alkali resistance, corrosion resistance and heat stability, has good stationarity, is slip-resisting, high in adhesive strength and has excellent temperature-resistant property, so that a product of the TPU hot-melt-adhesive laminated TPU foamed film has the advantage of long service life when being applied to the fields such as clothing manufacturing, shoemaking, building materials, automobile industry and the like.

Description

technical field [0001] The invention belongs to the technical field of foam products, and in particular relates to a TPU foam film affixed with TPU hot melt adhesive. Background technique [0002] TPU is an environmentally friendly high molecular polymer, which overcomes many defects of PVC and PU, not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, and can be used as PVC foam plastic film replacement of. However, the bonding performance of the TPU foamed film in the prior art is not strong, resulting in a short service life of the TPU foamed film. And the elasticity of TPU foam film in the prior art is not enough, and anti-yellowing performance is not good. [0003] In view of this, it is indeed necessary to provide a TPU hot melt adhesive with a TPU foam film, which combines the TPU hot melt adhesive and the TPU foam film to obtain a soft PVC material with good physical propertie...
