Embodiment 1

[0043] Jasmine Black

[0044] S1. Skin sorting

[0045] According to the leather surface disability standard, the raw leather blanks are screened, and the leather that meets the actual application requirements is screened out for batch production.

[0046] S2. Pieces of skin

[0047] Slice the skins that have been screened, and the thickness of the skins is required to be 1.2-1.4mm

[0048] S3. Fall soft

[0049] Soften for 2-6 hours depending on the requirements for the Jasmine variety.

[0050] S4. Dust removal

[0051] S5. Inside cover

[0052] Roll the lining paste on the back of the leather with a pass-through roller coater. The inside cover slurry contains 550 parts of water, 250 parts of water-based acrylic resin A, 180 parts of hydrazide organic matter, and 20 parts of phosphate in parts by weight, totaling 1000 parts.

[0053] S6. Primer

[0054] The primer coating process is carried out on the bottom layer composed of the leather surface finishing layer. The ...

Abstract

The invention relates to an environmental-friendly ecological vehicle leather process with low total volatile organic compounds (TVOC) and low odor, and belongs to the field of vehicle leather manufacturing. The environmental-friendly ecological vehicle leather process with the low TVOC and low odor is used for processing leather according to the processes such as leather blank sorting, splitting,milling, dedusting, lining-banding, prime coating, hanging and ventilating, embossing, processing a mixing layer, hanging and ventilating, top coating, and hanging and ventilating sequentially, so that the vehicle leather with the low TVOC and low odor is obtained. According to the environmental-friendly ecological vehicle leather process with the low TVOC and low odor provided by the invention,in the formula, a water-based material with the low TVOC for coating is adopted, so that the use of an organic solvent-containing cross-linking agent and an organic solvent-containing resin is avoided; in the coating engineering, the leather is ventilated and hung, so that the volatilization of the volatile organic compounds in the leather is accelerated, a leather TVOC emission test result is remarkably superior to leather produced by a conventional production process, the odor is remarkably improved, the limit value requirements of vehicle main engine plants on the volatile organic compoundsand the odor of a vehicle interior leather material can be met, a riding environment is improved, and the harm on a human body is reduced.

Description

technical field [0001] The invention belongs to the field of automobile leather production, in particular to a low-TVOC, low-odor, environment-friendly and ecological automobile leather technology. Background technique [0002] Many polymeric materials are used in the production process of automobile leather, such as polyurethane for finishing and crosslinking agent. The solvent and itself of the finishing material will have some volatile organic compounds. These polymeric materials will last for a long time after the leather is finished. Slow decomposition emits some harmful organic compounds such as formaldehyde, acetaldehyde, etc. and bad smells. All these volatile organic compounds—TVOC, gather in the small and closed space in the car, which is bad for the driving environment in the car , will cause physical harm to the passengers for a long time. [0003] As the automobile market pays more and more attention to the interior environment of the car, the leather produced ...
