Problems solved by technology

[0018] At present, for ordinary PVC artificial leather products, one of the main performance defects is poor hygienic performance
That is to say, the air permeability and water vapor permeability of ordinary PVC artificial leather are very poor, which limits the application field of PVC artificial leather, especially as shoe materials, sofa covering materials, and car seat coverings. When the material is applied, a big obstacle is encountered
[0019] There are two main reasons for the poor hygienic performance of PVC artificial leather: First, the cells in the PVC foamed artificial leather coating are closed-cell structures and have no air permeability, resulting in poor air permeability of ordinary PVC artificial leather. It can be said that it is almost It is airtight; second, there is no effective hydrophilic group in the ordinary PVC coating, which cannot effectively transmit moisture, so the water vapor permeability is very poor

Embodiment 1

[0046] The method provided by the invention comprises the following steps:

[0047] 1) In parts by weight, take 35 parts of PVC resin, 3 parts of collagen fiber, 35 parts of plasticizer, 5 parts of filler, 0.1 part of stabilizer, and 1 part of foaming agent and stir for 20 minutes until uniformly mixed to obtain a coating agent;

[0048]Among them, the PVC resin is a paste PVC resin, also called an emulsion PVC resin, and the degree of polymerization is 1050. Collagen fiber is the waste containing collagen fiber produced in the leather industry. The short fiber obtained after crushing has a fineness greater than 50 mesh. The plasticizer is dioctyl phthalate. The filler used is protein powder with a fineness greater than 400 mesh. The protein powder is prepared by adding anhydrous industrial sodium sulfate (yuanming powder) with 30% gelatin weight to an industrial gelatin solution with a mass fraction of 10%, salting out, flocculating, filtering, drying and pulverizing. The...

Abstract

The invention belongs to the technical field of artificial leather, and especially relates to a permeable collagen fiber / PVC composite artificial leather and a production method thereof. The method comprises the following steps: 1, preparing a coating agent; 2, directly knifing a woven cloth with the coating gent by adopting a knifing process; and 4, carrying out embossing and surface treatment to obtain the permeable collagen fiber / PVC composite artificial leather. The permeability and the moisture permeability of the permeable collagen fiber / PVC composite artificial leather obtained in the invention are 2000-2500ml / cm<2>.h and 1.3-1.5mg / cm<2>.h, and the permeable collagen fiber / PVC composite artificial leather has good permeability and moisture permeability, so the permeable collagen fiber / PVC composite artificial leather has an extremely good health performance.

Description

technical field [0001] The invention belongs to the technical field of artificial leather, in particular to a breathable collagen fiber / PVC composite artificial leather and a production method thereof. Background technique [0002] Artificial leather and synthetic leather are composite materials that simulate the tissue structure and performance of leather and can be used as leather substitutes. Usually, woven fabrics and non-woven fabrics are used to simulate the mesh layer of leather, and microporous polymer coatings are used to simulate the grain layer of leather. The obtained artificial leather and synthetic leather are similar to leather on the front and back, and are widely used in making shoes. , boots, bags and balls, etc. [0003] In the usual classification method, artificial leather is a leather-like material made of textile cloth as the base cloth and coated with polymer slurry. Most of them use polyvinyl chloride (PVC) as the coating agent, commonly known as "P...
