Abstract
The present invention relates to technical field of synthetic leather, diisocyanate and PEPA reaction are first obtained aqueous polyurethane emulsion by especially a kind of preparation method of PVC base fabrics coating；35 65% water-based acrylic resins are added in aqueous polyurethane emulsion again；It is again that diatomite, cellulose acetate nanofiber is ultra-dispersed in water, then remaining each component is mixed with aqueous polyurethane emulsion again；Remaining component includes flatting silica；Thickener；Lubricant；Adhesion promoter；Wetting agent；Water surplus.A kind of preparation method of PVC base fabrics coating of the present invention is a kind of water-based material using water as diluent, because water-based acrylic resin liquid used contains hydroxyl and carboxyl simultaneously, can both play hydrophilic interaction, solidification can be played again；With the addition of diatomite, give full play to suction-operated, so as to get synthetic leather clean environment firendly, be avoided that health be damaged；Surface also has wearability high, the characteristics of weather-proof good.
Description
Technical field
The present invention relates to technical field of synthetic leather, especially a kind of preparation method of PVC base fabrics coating.
Background technology
Synthetic leather be simulate natural leather the Nomenclature Composition and Structure of Complexes and can as its substitute material plastic products.Generally with through leaching
The non-woven fabrics of stain is lamina reticularis, and microporous polyurethane layer is made 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.It is widely used in making footwear, boots, case and bag and ball etc..
In the manufacture of existing synthetic leather, polyurethane resin, by dilution plus wood powder or other packing materials, by oozing
Saturating levelling, froth breaking, the technical process of solidification, can be using point two kinds of methods of wet method and dry method according to the performance of polyurethane resin
Leather is produced, good effect has been obtained, abundant return and benefit is also achieved.But needed in existing synthetic leather manufacture production
Substantial amounts of chemical substance is used, therefore very big harmfulness is generated to environmental protection and health.With society progress and
Growth in the living standard, material requirement proposes new requirement to synthetic leather product also with raising, health and environmental protection.
It is difficult to be cleaned totally with normal household cleaners that most synthetic leather surfaces, which are stained with after spot, in the market, is
Can clean surface spot, people can repeatedly clean with strong detergent, while as a result causing the spot to be eliminated, synthetic leather surface
Destroyed, gently then haze changes, and heavy then synthetic leather surface layer is damaged, results in the need for changing synthetic leather.
The content of the invention
It is an object of the invention to provide a kind of preparation method of PVC base fabrics coating, after the coating coating of preparation, make PVC
Synthetic leather has stronger scratch resistance, resistant and weather resistance.
Technical scheme is as follows：
A kind of preparation method of PVC base fabrics coating, comprises the following steps：
(1) by weight percentage, diisocyanate and PEPA are mixed, through pre-polymerization, chain extension, emulsification, a step is obtained
To aqueous polyurethane emulsion, go out kettle, obtain aqueous polyurethane emulsion；
(2) by weight percentage, 35-65% water-based acrylic resins are added in aqueous polyurethane emulsion, are put into height
On fast dispersion machine, stirred 10-15 minutes with 800-1200 revs/min of rotating speed, obtain basestocks；
(3) by weight percentage, by diatomite, cellulose acetate nanofiber and 50% water, it is put into high speed dispersor
On, with the ultra-dispersed 30min of 10000-12000 revs/min of high speed, obtain pre-dispersed material；
(4) by weight percentage, by flatting silica, thickener, lubricant, adhesion promoter, wetting agent, dispersed material and
50% water, is put on high speed dispersor, is stirred 20-60 minutes, then added pre-dispersed with 800-1200 revs/min of rotating speed
Material and pre-dispersed radiating material, are stirred 10 minutes with 800-1200 revs/min of rotating speed, you can；
Wherein each group is grouped into：
Wherein, water soluble acrylic acid tree is three wooden chemical industry EA1620 and WTB5124 mixture, and its weight ratio is 1:0.5-2.
Specifically, the flatting silica is silica.
Specifically, the thickener is water soluble polymer thickener.
Preferably, the water soluble polymer thickener is hydroxypropyl methyl cellulose or Sodium Hyaluronate.
Specifically, the lubricant is polysiloxanes.
Specifically, the adhesion promoter is modified epoxy phosphate.It can select to encourage europeanized work NEO-8980, can be with
The adhesive force of lifting material by a relatively large margin.
Specifically, the aqueous wetting agent is the alkanolamine or EVA of multiple functional radical.DISPERBYK- can be selected
181。
Specifically, the length of the cellulose acetate nanofiber is 200-400nm, a diameter of 40-80nm.
The beneficial effects of the invention are as follows：
(1) a kind of preparation method of PVC base fabrics coating of the invention is a kind of water-based material using water as diluent, due to
Water-based acrylic resin liquid used contains hydroxyl and carboxyl simultaneously, can both play hydrophilic interaction, solidification can be played again,
Only need to neutralize and can be obtained by the good aqueous solution of storage stability.
(2) a kind of preparation method of PVC base fabrics coating of the invention, diatomite is with the addition of in coating, suction is given full play to
Attached effect, so as to get synthetic leather clean environment firendly, be avoided that health be damaged；
(3) preparation method of a kind of PVC base fabrics coating of the invention, after the coating coating of preparation, surface also has wear-resisting
Property it is high, the characteristics of weather-proof good.
