Description
Technical field
The present invention relates to a kind of corium nursing waterproof film forming agents and preparation method thereof.
Background technique
Leather is to be lost hair or feathers and the physics such as tanning, chemical process is obtained has been denaturalized not perishable Animal Skin.Skin
The purposes of leather can be used for making a variety of daily necessities, such as leather shoes, clothes etc. than wide.The raw material that corium uses is
Natural leather.Natural leather is better than other materials in the performances such as flexible, ventilative, wear-resisting, folding, beauty, is that high-grade leathercraft is indispensable
Material.But this kind of product all easily seeps water, since wet weather or reasons, the leather surface such as rain are easy moist or contamination
To various moisture or steam.If corium product, without water-proofing treatment, leather is easy to rot, seriously shorten
The service life of leather and fur products also influences beautiful and consumer experience.Therefore, the water-proofing treatment of corium is necessary.
Corium waterproof care agent is generally required with effect below: not being changed original gloss of leather, color, is breathed freely
Property, leather surface can be permeated, and easy to use, simply, while be suitable for production.CN103132315A,CN104479551A,
The documents such as CN106497411A, CN107761381A all disclose waterproofing agent for leather class product.But existing waterproofing agent for leather,
Most waterproof effect is poor, and leather is easy to fade, and stability is low, cannot be durable, requires further improvement and perfect.Cause
This, needs to develop a kind of good water-proof effect at present, flexible modulation can be needed to produce according to product, and wieldy corium protects
Waterproof product is managed, the requirement in market is met.
Summary of the invention
The purpose of the present invention is to provide a kind of corium nursing waterproof film forming agents and preparation method thereof, which nurses waterproof
Film forming agent can make leather surface form a kind of very thin waterproof, hydrophobic effect, while can be adjusted according to different leather products
The thickness of film forming agent.
The technical solution used in the present invention is:
A kind of corium nursing waterproof film forming agent, is made of the raw material of following mass percent:
Corium is nursed in waterproof film forming agent, and fluoropolymer emulsion is Studies of Perfluoroacrylates Polymer Emulsions.
Corium is nursed in waterproof film forming agent, and the ammonia value range of amido silicon oil is 0.2mmol/g~0.6mmol/g.
Corium is nursed in waterproof film forming agent, and water is at least one of deionized water, distilled water, pure water.
The preparation method of this corium nursing waterproof film forming agent, is to weigh raw material according to above-mentioned composition, is mixed, obtains
Waterproof film forming agent is nursed to corium.
In preparation method, be mixed be specifically material is placed in reaction kettle, be heated under vacuum conditions 80 DEG C~
90 DEG C, 50min~70min is mixed.
The application method of this corium nursing waterproof film forming agent is by corium nursing waterproof film forming agent spraying or to be applied to true
Skin product surface.
The beneficial effects of the present invention are:
Corium nursing waterproof film forming agent of the invention can form one layer of waterproof, antifouling protection on the surface of all corium
Film reaches hydrophobic effect while protecting corium.
It is specific as follows:
1) in fluoropolymer emulsion addition system, can disperse to form stable dispersion in the solution, in corium table
Face forms a kind of special hydrophobic waterproof effect, does not influence the gas permeability on corium surface.(per) fluoropolymer non-pole in aqueous solution
Property group (such as hydrocarbon chain) mutually draw close association, form hydrophobic effect.I.e. nonpolarity divides the result of hydrophobic effect in an aqueous medium
There are significant sucking actions between son or group.But hydrophobic meaning, which is not necessarily referring to have between such nonpolar molecule and moisture, repels each other
Van der Waals force is not present in effect, but illustrates to show to flee from from mutually associating in such nonpolar molecule or group itself
The trend of aqueous medium, improves contact angle, and similar lotus leaf effect occurs in water droplet to corium surface.
2) amido silicon oil, isomerous tridecanol surfactant, modified polyether silicone oil can play the role of clean, oil to skin
Brightness penetrates into hide fiber, keeps skin soft.Aliphatic polyurethane resin can be according to added mixed liquor proportion adjustment in corium table
The film forming thickness in face plays protection corium surface, while achieving the effect that together with waterproofing agent more hydrophobic.Be added isopropanol and
Solution evaporation speed is adjusted in deionized water, isopropanol, and deionized water can effectively dissolve various substances, more convenient to use.
