Embodiment 1

[0049] Follow the steps below to prepare low-odor PVC artificial leather:

[0050] Slurry mixing: According to the formulas of the PVC skin layer and the foam layer given in Table 1, the slurry of the PVC skin layer and the slurry of the PVC foam layer were prepared respectively by conventional stirring and mixing.

[0051] Coating: send the release paper, after the sent release paper is stored by the release paper (through the storage of the release paper, there is no need to stop when the release paper is replaced, so as to realize continuous production), firstly coat on the coating machine Spread the slurry of the PVC skin layer and dry it in a drying pipeline at 180°C for 30 seconds. After cooling, it is further sent to the coating machine, and the slurry of the PVC foam layer is coated on the PVC skin layer, and baked in a drying pipeline at 180° C. for 30 seconds. After cooling, the surface of the PVC foam layer is coated with a backcoat with water-based polyurethane sy...

Embodiment 2

[0059] According to the formula of PVC skin layer and foam layer given in Table 2, according to the preparation method of PVC artificial leather in Example 1, prepare PVC artificial leather product. The PVC artificial leather thus obtained can be applied to automobile door panels.

Abstract

The invention relates to a skin layer composition for forming low-odor PVC artificial leather. The skin layer composition comprises PVC resin, a plasticizer and a stabilizer. The invention also relates to a foaming layer composition for forming the low-odor PVC artificial leather. The foaming layer composition comprises PVC resin, a plasticizer, a stabilizer and a foaming agent, wherein the plasticizer is selected from dialkyl phthalate, preferably alkyl alcohol forming the dialkyl phthalate is linear alcohol, preferably the linear alcohol has a carbon chain length of C9 to C13, particularly preferably C10 and/or C12, further preferably C10 and C12 mixed in a ratio of 10: 1 to 1: 10, particularly 8: 2 to 5: 5. The invention also relates to the low-odor PVC artificial leather. The low-odorPVC artificial leather comprises a skin layer formed by the skin layer composition and/or a foaming layer formed by the foaming layer composition. The odor level of the PVC artificial leather is effectively reduced, and the requirements of customers on product pleasure and health are met.

Description

technical field [0001] The present invention relates to a skin layer composition for forming low-odor PVC artificial leather, a foam layer composition, and low-odor PVC comprising a skin layer formed from the skin layer composition and a foam layer formed from the foam layer composition artificial leather. Background technique [0002] Polyvinyl chloride (ie PVC) is the main raw material in the production and development of artificial leather, and is widely used in automotive interiors. PVC with a high degree of polymerization has a high melting temperature, poor fluidity of the melt, and is difficult to process. Therefore, in order to improve the fluidity of PVC, reduce the processing temperature, and facilitate production and processing, plasticizers must be added to PVC. However, the commonly used plasticizers will emit a strong odor, and other additives added during PVC processing, such as stabilizers, foaming agents, etc., may also emit odor. In addition, in order to ...
