～15min baking oven ripening；
(4) separating rolling: carry out release paper stripping after product ripening step 3 obtained, rolling obtains required without any
The ecology of organic solvent imitative super fine automobile leather.
Beneficial effect: the present invention, compared with conventional art, has the advantage that
1. the present invention has stopped to pollute from source, without any organic solvent in raw materials, to Producer and user
All without any harm, product environmental protection, ecology, for synthetic leather industry current forefront product.Synthetic leather industry automobile leather will be overturned
Existing raw materials for production and technique, TVOC is close to 0；
2. energy consumption is low, because this product is without solvent, it is not necessary to solvent discharge, greatly reduces comprehensive energy consumption；
3. investment reduction, because this product is without solvent, it is not necessary to solvent recovery and wastewater treatment equipment, reduces scale of investment；
4. product quality is excellent: the present invention, for reaching low VOC requirement, uses solvent-free polyurethane resin and belongs to double-component friendship
Connection curing type, and film forming is plentiful, its physical property, considerably beyond solvent borne polyurethane, has splendid chemical resistance.
