Problems solved by technology

PVC tablecloths are affecting people's lives more and more. PVC tablecloths on the market continue to be produced using traditional production processes. PVC products have always used calendering to produce raw material films, and one or two printing processes on the films to realize PVC products. The added value, because PVC is not degradable,

Example Embodiment

[0024] Embodiment 1: The present invention is a degradable TPU foam layer 2 cotton tablecloth, which includes a TPU bottom layer 1, a foam layer 2, and a three-dimensional cotton patch layer 3 from bottom to top, and the TPU bottom layer 1 adopts a three-liquid type quantitative Mixed, and made by continuous twin-screw extrusion. The twin-screw continuous extruding stage rotates in the same direction and is completely toothed. The TPU masterbatch includes the following components: high molecular polyester diol (PES) 65 parts, polyethylene adipate (PEA) 35 parts, polyethylene adipate lactide (PDA) 25 parts, polyethylene butylene adipate (PBA) 20 parts .

[0025] In the twin-screw continuous extrusion stage, vacuum buffering is simultaneously used to achieve the purpose of strong TPU masterbatch texture.

[0026] The polyethylene adipate (PEA) has a molecular weight of M=2000 and a hydroxyl value of 55±3 mgKOH / g, and the polyethylene adipate (PDA) has a molecular weight of M=20...

Abstract

The invention discloses a degradable thermoplastic polyurethane TPU cotton tablecloth with a foaming layer. The tablecloth comprises a TPU bottom layer, the foaming layer and a three-dimensional cotton layer from bottom to top, wherein the TPU bottom layer is manufactured by adopting three-liquid-type quantitative mixing and twin-screw continuous extrusion; two shafts co-rotate and completely meshin the twin-screw continuous extrusion stage; and TPU master batch comprises the following components: 65-70 parts of polymer polyester diol (PES), 35-50 parts of polyhexan acid glycol ester (PEA), 25-35 parts of polyethylene lactone glycol adipate (PDA) and 20-30 parts of polyethylene buthlene glycol adipate (PBA). The tablecloth disclosed by the invention is degradable, water-proof, oil-proof,skid-proof, mold-resistant, wear-resistant, environmentally friendly and non-toxic.

Description

technical field [0001] The invention relates to a tablecloth production process, in particular to a cotton-coated tablecloth with a degradable TPU foam layer. Background technique [0002] Tablecloth products play a pivotal role in home decoration. More and more people have a large demand and high requirements for tablecloths in order to pursue a perfect life. PVC tablecloths are affecting people's lives more and more. PVC tablecloths on the market continue to be produced using traditional production processes. PVC products have always used calendering to produce raw material films, and one or two printing processes on the films to realize PVC products. The added value of PVC is non-degradable, so this type of product is not environmentally friendly. Moreover, the traditional PVC printing tablecloth production process is cumbersome, and because the PVC material itself is easy to age, has a single texture, poor hand feeling, and the thickness is limited by cost conditions, i...
