Description
Technical field：
The present invention relates to synthetic leather function additive technical field, and in particular to a kind of to be peeled off suitable for the aqueous high of synthetic leather
Auxiliary agent.
Background technology：
Synthetic leather, the Nomenclature Composition and Structure of Complexes of simulation natural leather simultaneously can be used as the plastic products of its substitute material.Generally with through leaching
The non-woven fabrics of stain is lamina reticularis, and microvoid polyurethane layer is obtained as grain layer.Its positive and negative is all quite similar with leather, and has
There is certain gas permeability, than common artificial leather closer to natural leather, be widely used in making footwear, boots, case and bag and ball etc..
Release liners, are the transfer coated indispensable carrier materials of processing, assign synthetic leather decorative pattern attractive in appearance.In synthetic leather
In process, coating agent equably covers with paint, lacquer, colour wash, etc. the surface to release liners first, and release liners enter baking oven with coating agent, and solvent is waved
Film is peeled off from release liners after film forming, with composite for base fabric on paper after hair.Release liners are made up of paper substrate and release coating, right
Coated film has certain Adhering capacity, if Adhering capacity is too big, coated film can not successfully from release after with composite for base fabric
Peeled off on paper and be transferred in base fabric, caused film forming discontinuous and tear the phenomenons such as release liners, reduce release liners reusable
Number of times.
The content of the invention：
The technical problems to be solved by the invention are that a kind of peeling effect of offer is good, are conducive to increase release liners to repeat to make
With number of times auxiliary agent is peeled off suitable for the aqueous high of synthetic leather.
The technical problems to be solved by the invention are realized using following technical scheme：
It is a kind of to peel off auxiliary agent suitable for the aqueous high of synthetic leather, it is made up of the raw material of following parts by weight：
OPE -15-20 parts of HPMA graft copolymer, ultra-fine polytetrafluorethylepowder powder 5-10
Part, flyash 3-5 parts, water-soluble modified PVPP 3-5 parts, aluminium-magnesium silicate 1-2 parts, glass fiber powder 1-2 parts, nano oxygen

Its preparation method comprises the following steps：
(1) to polyethylene glycol oxide and N-hydroxy-succinamide sulfonate sodium is added in ultra-fine polytetrafluorethylepowder powder, with 5
DEG C/programming rate of min is warming up to 115-120 DEG C of insulation mixing 15-30min, add nano aluminium oxide and 1,3- dimethyl-
2- imidazolones, continue, in 115-120 DEG C of insulation mixing 10-15min, then to naturally cool to room temperature, obtain final product material I；
(2) it is poly- to addition OPE-HPMA graft copolymer in water and water-soluble modified crosslinking
Dimension ketone, stands 15-30min after dissolving completely, add sodium gluconate, and be warming up to backflow with the programming rate of 5 DEG C/min
State insulation mixing 10-15min, obtains final product material II；
(3) while hot to material I, flyash, aluminium-magnesium silicate and glass fiber powder is added in material II, after being sufficiently mixed again
Backflow insulation mixing 15-30min, grinds during gained mixed liquor then is sent into ball mill, finally crosses 200-300 mesh sieves.
The OPE-HPMA graft copolymer is by OPE and hydrolyzed polymaleic anhydride
Acid anhydride is after graft copolymerization and modified treatment is obtained, and its specific preparation method is：Poly- horse is hydrolyzed to being added in OPE
Come acid anhydrides and initiator, be incubated mixing 0.5-1h after being heated to molten condition, and 55- is cooled to the cooling rate of 5 DEG C/min
60 DEG C, poloxamer, PAMA and PDDA are added, using micro- after being sufficiently mixed
Ripple processor microwave treatment 3-5min, is transferred in 0-5 DEG C of environment and stands after 1-2h microwave treatment 3-5min again, is subsequently adding 5-
10 DEG C of water, then reflux state insulation mixing 15-30min is warming up to the programming rate of 5 DEG C/min, finally by gained mixed solution
In feeding spray dryer, dry gained particle and be made micro mist through micronizer, obtain final product the poly- Malaysia of OPE-hydrolysis
Acid anhydrides graft copolymer.
The condition of work of the microwave treater is：Rated frequency 2450MHz, input power 1300W, power output
700W。
The OPE, HPMA, initiator, poloxamer, PAMA, poly- two

The initiator is selected from the one kind in benzoyl peroxide, cumyl peroxide, di-tert-butyl peroxide.
Made OPE-HPMA graft copolymer not only has excellent fissility, also passes through
Modification makes its soluble in water, aqueous remover is formed, so as to improve use the feature of environmental protection.
The water-soluble modified PVPP is obtained by the modified treatment of PVPP, and its specific preparation method is：
To addition N hydroxymethyl acrylamide and rilanit special in PVPP, and 65- is warming up to the programming rate of 5 DEG C/min
70 DEG C of insulation mixing 15-30min, add allyl glycidyl ether and hexamethylolmelamine pregnancy ether, continue with 5
DEG C/programming rate of min is warming up to 115-120 DEG C of insulation mixing 10-15min, treats that gained mixture naturally cools to 45-50 DEG C
25-30 DEG C of water is added afterwards, reflux state insulation mixing 15-30min is warming up to the programming rate of 5 DEG C/min again, then certainly
Room temperature is so cooled to, in gained mixed liquor feeding freeze drier, gained solid is dried and is made micro mist through micronizer, obtained final product
Water-soluble modified PVPP.
The PVPP, N hydroxymethyl acrylamide, rilanit special, allyl glycidyl ether, hexamethylol
The mass ratio of melamine pregnancy ether and water is 10-15:2-3:0.5-1:1-2:0.05-0.1:40-70.
By the modification to PVPP, its water solubility is assigned while its fissility is retained, be beneficial to molten
Yu Shuizhong forms aqueous remover.
The beneficial effects of the invention are as follows：The present invention is based on OPE-HPMA graft copolymer
Want raw material, association is obtained with multiple auxiliary materials and auxiliary agent and peels off auxiliary agent suitable for the aqueous high of synthetic leather, the stripping auxiliary agent using water as
Retarder thinner, it is to avoid the safety in utilization problem existed using volatile harmful organic solvent；And stripping auxiliary agent user
Just, by its even application in release liners surface when using, treat that it dries coating synthetic leather in backward release liners and prepares slurry, film
Can easily be peeled off from release liners with after composite for base fabric, be not in destroy film and tear showing for release liners in stripping process
As so that it is guaranteed that the continuity and surface quality of film and the increase reusable number of times of release liners.
