Description
Technical field
The invention belongs to polyurethane surface treating agent fields, and in particular to a kind of aqueous from delustring skin sense no-solvent polyurethane
Matt surface inorganic agent.
Background technique
Synthetic leather is a kind of flexible polyurethane product, and traditional synthetic leather surface treating agent generally uses solvent polyurethane system
Standby, use brings huge destruction to environment, and water polyurethane surface treating agent can be very good to solve synthetic leather surface
The pollution problem of inorganic agent.Delustring processing is one of most common skin effect in synthetic leather surface treatment, it can assign synthesis
Remove from office soft natural gloss, good sense of touch, the deep widespread love by market.Traditional synthetic leather delustring processing is using inorganic
Silica is as matting particles, after compounding with polyurethane finishing agent, has good extinction effect, but silica is nothing
For the polyurethane of machine object, inorganic aerosil and organic phase there is organic and inorganic interface, synthetic leather is flexible polyurethane product,
Silica and polyurethane finishing agent meeting with preferable elongation percentage, when synthetic leather is stretched, in frosting inorganic agent
The interfacial separation for generating organic phase and inorganic phase influences the aesthetics of synthetic leather used so that synthetic leather surface be caused to whiten.
Summary of the invention
For the problems of the prior art, the present invention provides a kind of aqueous matt table of skin sense no-solvent polyurethane from delustring
Surface treatment agent solves the separation of the organic phase and inorganic phase of silica and polyurethane finishing agent in existing inorganic agent, causes
The problem of synthetic leather surface is whitened, using being used in combination for wetting agent and defoaming agent, not only reduce surface can, while reducing thin
Film bubble is able to ascend the adhesion of surface treating agent.
To realize the above technical purpose, the technical scheme is that
A kind of aqueous matt surface inorganic agent of skin sense no-solvent polyurethane from delustring, including following quality formula preparation and
At:
100 parts of aqueous delustring polyurethane resin, 150 parts of water, UL-5125:4 parts of wetting agent, F-530:0.5 parts of defoaming agent,
8807:5 parts of polyurethane thickener；
Preparation method:
Step 1, raw material is weighed according to above-mentioned formula, for use；
Step 2, by aqueous delustring polyurethane resin, water, wetting agent, defoaming agent and polyurethane thickener sequentially add to point
Dissipate and stir 1h in cylinder, after obtain matt surface inorganic agent, the mixing speed of the stirring is 500r/min.
Application method: being put into agitating device for matt surface inorganic agent and stir evenly, then equal using QTS stick spreaders
It is even to be coated in PVC synthetic leather surface, it is finally putting into 100 DEG C of drying in baking oven.
The quality formula of the aqueous delustring polyurethane resin is as follows:
140-150 parts of polyether polyol, 20-25 parts of hexamethylene diisocyanate, 0.05 part of organic bismuth catalyst, ethyoxyl
6-7 parts of polymer diol, 3-5 parts of isophorone diisocyanate, 0.2-0.5 parts of dimethylolpropionic acid, 90-100 parts of deionized water,
3-5 parts of ethylenediamine.

Wetting agent UL-5125 is a kind of high performance organosilicon wetting agent, has good osmotic effect to microporous substrate, drop
The low defect of film, while also having the performance for reducing bubble；Wetting agent itself can reduce surface energy, promote liquid to base
Material soaks effect, reduces the gap between polyurethane and substrate, promotes adhesiving effect and adhesion strength.At matt surface
When reason agent is coated uniformly on the synthetic leather surface PVC, wetting agent can be infiltrated into the micropore of leather surface, can guarantee
The planarization on surface, while the characteristic of wetting agent itself can guarantee the wetting effect on surface, and polyurethane is promoted to infiltrate into micropore
It is interior, surface smoothness is formed, skin sense and glossiness are promoted；The performance for reducing bubble of both wetting agent and defoaming agent simultaneously.
The pure and mild dimethylolpropionic acid of polyether polyols, by polycondensation reaction, forms polyether-type under the action of organic bismuth catalyst
Polyurethane.Submissive performance is good under polyether polyurethane low temperature, has good skin sense, while excellent hydrolysis resistance, Neng Gouman
The demand actually used enough.Polyether-polyurethane viscosity is low simultaneously, by matching with polyurethane thickener, has been able to solve viscosity
Low problem.
From the above, it can be seen that the present invention has following advantages:
1. point that the present invention solves the organic phase and inorganic phase of silica and polyurethane finishing agent in existing inorganic agent
From, the problem of causing synthetic leather surface to whiten, using being used in combination for wetting agent and defoaming agent, not only reduce surface can, together
When reduce thin film air bubble, be able to ascend the adhesion of surface treating agent.
2. the present invention, as polyurethane material, can have low-temperature flexibility using polyethers polyurethane, embody good
Skin sense, simultaneously because surface uniformity, also has good delustring performance.
