Preferably, in the flavouring method of described artificial leather, in described step (3), described essence be rose essence or
Lavandula angustifolia essence.
Present invention improves the taste of artificial leather is so as to naturally can give out fragrance when using, thus increased people
The comfort level that uses.
Specific embodiment
The present invention is described in further detail below, with make those skilled in the art with reference to specification word being capable of evidence
To implement.
The present invention provides a kind of flavouring method of artificial leather, comprising:
Step (1) applies on aqueouss pu surface layer scrapes one layer of aqueouss pu foaming layer, and the thickness of foaming layer is 0.1～0.2mm, plus
Hot temperature is 100～112 DEG C, and heat time heating time is 30～35min；
Step (2) applies in foaming layer and scrapes aqueouss pu adhesive, and base fabric is attached in foaming layer, and makes aqueouss pu gluing
Agent penetrates base fabric, then is heated, and heating-up temperature is 140～143 DEG C, is heated to making aqueouss pu adhesive be in half-dried shape
State；
Flavouring agent is coated on the aqueouss pu adhesive penetrating base fabric by step (3), forms fragrance oxidant layer, and side applies
Cover side concussion, coating speed is 2～3cm3/ s, concussion frequency is 10～20 times/min, after the completion of coating, sends into a pair phase each other
Carry out roll-in 1 time between the pressure roller rotating, wherein, flavouring agent is to be mixed by beta-schardinger dextrin-and perfume particles, essence
The particle diameter of grain is 1～2mm；
Aqueous polyurethane and cross-linking agent are coated in fragrance oxidant layer step (4), heating, and heating-up temperature is 150～160
DEG C, heat time heating time is 1～2h, so that aqueous polyurethane and cross-linking agents form decorative layer, and in the coating poly- ammonia of aqueouss
Also shaken while ester and cross-linking agent, concussion frequency is 80～84 times/min；
The product that step (4) obtains is sent into and is carried out roll-in, linear speed between the pressure roller relatively rotating with respect to each other for a pair by step (5)
For 20～25cm/min, it is repeated 3～6 times.
In the present invention, aqueouss pu adhesive was impregnated with base fabric, during heating, made aqueouss pu adhesive be in half-dried state,
So flavouring agent can partly be mixed with aqueouss pu adhesive, and protects under the adhesive attraction of aqueouss pu adhesive
Hold between base fabric and decorative layer.The such coating method of flavouring agent can ensure that flavouring agent is lentamente released in the air,
Without promptly dissipating, thus ensureing that preparation-obtained artificial leather remains able to discharge fragrance through long-time use.
And, the particle diameter of perfume particles is 1～2mm, and by concussion, perfume particles can be inlayed in aqueouss pu adhesive.
After forming decorative layer, perfume particles can lentamente be volatilized and be diminished, and make fragrance gradually dissipate out.In above process, fragrant
Smart granule is not to have fully embedded into aqueouss pu adhesive, and simply a part is embedded in aqueouss pu adhesive, another portion
Divide and be then embedded in decorative layer.
Because aqueous polyurethane and cross-linking agent are in coating procedure, may be by the obstruct of perfume particles in essence
Surrounding's formation bubble of grain, and then affect the intensity of decorative layer, therefore, the occurrence of in order to reduce above-mentioned, in coating aqueouss
When polyurethane and cross-linking agent, also carry out concussion process, promote aqueous polyurethane and cross-linking agent to be evenly distributed on the week of perfume particles
Enclose.
In order to promote to be tightly combined further between different layers, and in order to promote perfume particles and aqueouss pu adhesive with
And be tightly combined and decorative layer between, there is no small hole or bubble, after forming decorative layer, be also repeated a number of times roller
Pressure.In addition, in step (3), after coating is complete, being also carried out roll-in, perfume particles are also made to be immersed in aqueouss pu as far as possible
In adhesive, thus extending the time of fragrance release.
The artificial leather of the present invention toasts 240 hours at 90 DEG C, and fragrance still retains 52%.
Preferably, in the flavouring method of described artificial leather, in described step (1), the thickness of foaming layer is 0.15mm.
Preferably, in the flavouring method of described artificial leather, in described step (1), heating-up temperature is 110 DEG C, heating
Time is 30min.
Preferably, in the flavouring method of described artificial leather, in described step (2), heating-up temperature is 140 DEG C.
Preferably, in the flavouring method of described artificial leather, in described step (4), heating-up temperature is 156 DEG C, heating
Time is 1h.
Preferably, in the flavouring method of described artificial leather, in described step (3), described essence be rose essence or
Lavandula angustifolia essence.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in description and embodiment
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Realize other modification, therefore under the general concept being limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details.
