Description
Technical field
The present invention relates to leather processing field, and in particular to a kind of manufacture method of environmentally friendly vehicle interior decoration leather.
Background technology
With present industrialization, informationalized development, while living standard is improved, spy wants people to quality of the life
Seek more and more higher.
The significantly convenient trip mode of people of popularization of automobile, while the development of automobile is with the carrying out of the industrial revolution,
More efficient automobile power source now is gradually developed into by numerous power cars such as steam, gasoline, electric power.
Automobile is when in use, it is contemplated that during the situation such as dynamic braking, the requirement of the situation such as outward appearance, comfort level for automobile
Also more and more higher, the development of automobile industry of China are slower, fall behind other in the processing method of technique such as overall production technique
Manufacturer.Generally during automobile production, leather is also the important raw and processed materials as ornament.
Dermatine, it be on woven fabric base or nonwoven fabric base, by various different formulations the foaming such as PVC and PU or cover
Film processing and fabricating is formed, and can require to be processed into according to varying strength and color, gloss, floral designs etc., with pattern product
The characteristics of kind of various, water resistance is good, not care about one's appearance is neat, utilization rate is high and price is cheap with respect to corium, but the overwhelming majority is artificial
Leather, its feel and elasticity are unable to reach the effect of corium；Its longitudinal section, it can be seen that trickle crafters, Bu Ji or top layer
Thin film and dry wizened staple fibre.Traditional leather is applied directly on automobile, due to dermatine it is most of in order to save
Cost-saving, in processing, in order to more easily be adhered to various leathers, can use substantial amounts of adhesive agent, and for viscous
Attached dose of use, the material composition for various chemical corrosivities that great majority are adopted, is connect for a long time with the leather of upholstery
Touch, more virose chemical substances can be dissipated, human body is produced and is greatly injured.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of manufacture method of environmentally friendly vehicle interior decoration leather so that interior trim
Leather directly can improve the fastness of leather using hot-press molding method and can realize the harm without adhesive agent.
To realize object above, the present invention is achieved by the following technical programs：
A kind of manufacture method of environmentally friendly vehicle interior decoration leather, is disposed with bottom, nonwoven layer, composite bed and top layer, system
Preparation Method is as follows：
1) bottom, takes soft leather, is suppressed, and is then cut into bottom；
2) nonwoven layer, by step 1) process after soft leather medial surface heated, it is then that non-woven fabrics are directly warm
It is depressed into soft leather medial surface；
3) composite bed, by polypropylene, terylene, foaming agent is through multiple acupuncture hot rolling treatment in addition, then carries out pressure roller extruding
Molding, is attached to step 2 while hot) nonwoven layer on；
4) top layer, by one layer of thin leather layer of composite bed surface hot calendering bonding, then carries out blow process；
5) to 4) carrying out deburring grinding process the step of machine-shaping.
Preferably, described step 2) in the temperature control that heated of soft leather medial surface at 50-150 DEG C, and
Process time is 5-15 minutes.
Preferably, described step 3) in polypropylene, terylene before processing first blended, then mix with foaming agent again.
Preferably, described step 3) in temperature while hot be 60-70 DEG C.
Preferably, described step 3) in composite bed pressure roller extrusion molding thickness be 0.5-1mm.
Preferably, described step 4) product surface after molding sprays one layer of bright layer again.
The invention provides a kind of manufacture method of environmentally friendly vehicle interior decoration leather, interior decoration leather product be disposed with bottom,
Nonwoven layer, composite bed and top layer.The nonwoven layer that the medial surface of bottom is arranged causes for coarse shape, to be easy to composite bed in hot pressing
Fixation after molding, while the polypropylene, terylene, foaming agent in composite bed employing can effectively improve the soft of interior decoration leather interiors of products
It is soft, and polypropylene, terylene can also improve certain toughness, and the outside on top layer also carries out spraying bright layer, can increase whole product
The glossiness of product.Whole technological process preparation method can further genralrlization in actual commercial production.
