Pvc leather use aqueouss matte skin feel treatment agent, further relate to the preparation method of this pvc leather aqueouss matte skin feel treatment agent.
Background technology
Pvc keratin is light, water-fast, low cost, therefore is widely used in making clothing, shoes and hats, case and bag, furniture, ornament and various
Industry accessories.Produce during pvc artificial leather due to adding the materials such as substantial amounts of plasticizer so that the pvc artificial leather produced
Gloss, feel are all not ideal enough.The production process of leather must be surface-treated to leather, give leather surface
The comfortable feel such as smooth, soft, dumb light, beautiful outward appearance, and the effect of scratch resistance, resistance to alcohol and resistant.Existing pvc removes from office table
Face inorganic agent is mostly agent at solvent-borne type pu table, because taste greatly, can remain through the leather at table, and dmf, toluene, butanone etc. are poisonous to be had
Evil material, with the increase of people's environmental consciousness, the restriction of national policy, agent at solvent-borne type pvc leather table is gradually exiting city
?.And agent at existing aqueouss pvc leather dumb light table, some adhesive force are not enough, and wear-resisting very poor, scratch resistance is poor, and some dullness are inadequate
Low, blackness or thoroughly degree are not.At simple coarse feel pvc leather table, agent is difficult to meet in home decoration, household electrical appliances, furniture, automobile
The higher and higher requirement such as interior trim.
Illustrate in publication 201520563468.1 that a kind of scratch resistance resists dirty silk to slide high dumb light pvc decorating film, its
In be related to a kind of scratch resistance and resist dirty silk to slide high dumb light pvc feel coating, its dullness, in 5-10, does not far reach high in industry
Dumb light and the atomized surface effect of high blackness.
Illustrate in publication 201310028041.7 a kind of for pvc artificial leather surface treatment aqueous treatment agent and its
Preparation method, it still needs to use solvent, does not accomplish environmental protection, the manufacture method that this patent is proposed, and its Stability of Slurry is very poor, sinks
Layering of forming sediment is serious, and slurry standing time limits to very much.
A kind of calendering pvc leather aqueouss matte surface finishing agent and its preparation side is illustrated in publication 201110249673.7
Method, it is that pu resin compounds aerosil, by this patent way, compounds pulp using all types of pu resins being previously mentioned
Material, experimental result is shown in very puckery in feel, is carried and be provided that the tactile sense of fullness of handss and exquisite quality sense is not science in this patent
's；And this patent can cause slurry to be layered from polyurethane associative thickener, deficient in stability, thus lack practical application valency
Value.In cited specific embodiments in this patent, 8, this situation can not can be regarded as matte surface finishing agent to its dullness.
A kind of use for synthetic leather aqueouss pu polishing agent and preparation method thereof is illustrated in publication 201110174579.x,
Its formula by waterborne polyurethane resin gloss oil, modified polyurethane emulsion, wax emulsion, silicon dioxide flatting silica, organosilicon levelling agent,
Organic silicon defoamer, aqueous polyurethane thickener and water composition, this patent is a kind of polishing agent, is need to be through throwing after process
The bright face effect of light.
A kind of use for synthetic leather aqueouss pu matte surface finishing agent is illustrated, its formula has aqueouss in publication 200910212603.7
Polyurethane resin, water, silicon modified organic polymer, organosilicon levelling agent, organic silicon defoamer, aqueous polyurethane thickener and change
Property organosilicon flatting silica composition, this patent is use for synthetic leather aqueouss pu matte surface finishing agent, because pvc leather in contain a large amount of plasticizers, institute
Pvc leather is not suitable for it.
A kind of skin sense polyurethane leather surface inorganic agent and preparation method thereof is illustrated in publication 201310113085.x,
This surface conditioning agent is solvent-borne type common skin sense leather surface treatment agent.
Elaborate in publication 201110249656.3 to roll pvc leather aqueous surface-treating agent, this patent is applied to
The aqueous surface-treating agent of the pvc leather of rolling process.
Accordingly, it would be desirable to a kind of new pvc leather of exploitation uses aqueouss matte surface finishing agent, atomized surface effect is good, and thick and heavy skin sense is good, resistance to
Dirty, environmental protection, adhesive force is good simultaneously, scratch resistance, resistance to tortuous, resistance to jungle；Can meet in home decoration, household electrical appliances, furniture, automotive trim
Deng requirement higher and higher to skin sense and resistant etc..
