Description
Technical field
The present invention relates to a kind of aqueous polyurethane coating for woolen surface and preparation method thereof.
Background technology
The base materials such as leather, synthetic leather, fabric, paper and plastics are covered with paint, lacquer, colour wash, etc. the sense of formation matte be quite received by the market, conventional preparation method is by sanding, frosted or the method generation pile effects adding fine hair powder, but effects on surface coating can produce certain destruction, or the interpolation of fine hair powder affects the mechanical property of top coat.
Summary of the invention
In order to solve the technical problem existed in prior art, an object of the present invention is to provide one can direct spraying roller coating or blade coating leather, synthetic leather, fabric, paper and frosting, just pile effects can be produced, neither affect coatingsurface mechanical property, in turn simplify the aqueous polyurethane coating for woolen surface of production technique.In order to realize this object, the technical solution adopted in the present invention is:
A kind of aqueous polyurethane coating for woolen surface, raw materials is made up of following component:
Polyvalent alcohol 40 ~ 80 parts
Glycol chain extender 6 ~ 15 parts
Aliphatic isocyanates 30 ~ 40 parts
Dimethylol propionic acid 2 ~ 3.5 parts
Solvent 10 ~ 15 parts
Triethylamine 1.5 ~ 3 parts
Diethylenetriamine 1 ~ 5 part
Soxylat A 25-7 compound emulsifying agent 1 ~ 2 part
Thickening material 1 ~ 2 part.
Preferably, the molecular weight of described polyvalent alcohol is 800 ~ 2000, and described polyvalent alcohol is polytetrahydrofuran or polycaprolactone; Described aliphatic isocyanates is hydrogenation of benzene dicyclohexylmethane diisocyanate (MDI) or isophorone diisocyanate (IPDI); Described glycol chain extender is neopentyl glycol or BDO; Described solvent is dioxane.
Two of object of the present invention is the preparation method providing a kind of aqueous polyurethane coating for woolen surface, and in order to realize this object, the technical solution adopted in the present invention is:
Aliphatic isocyanates and polyvalent alcohol is first added in reaction vessel, 85 DEG C are reacted 2 hours, add glycol chain extender and dimethylol propionic acid again, in 70 DEG C of reactions 4 hours, add solvent and control viscosity, be cooled to 50 DEG C, add triethylamine and compound emulsifying agent, add diethylenetriamine after emulsification and react 30 minutes, finally add thickening material, discharging.
Aqueous polyurethane coating for woolen surface of the present invention, by controlling aqueous polyurethane hydrophilic radical content below stagnation point, make macromolecular chain be in rolled state in emulsion, the particulate in emulsion is large and coarse, thus pile effects when reaching film forming.But hydrophilic radical content is low, is not easy to form stable emulsion, needs to be solved by other means.Aqueous polyurethane coating for woolen surface preparation method of the present invention, adopt unique synthesis and emulsifying process, prepare the polyaminoester emulsion of unique properties, synthesis technique aspect, the method such as step-by-step polymerization and rear chain extension of employing, the aqueous polyurethane coating for woolen surface of preparation can direct spraying roller coating or blade coating leather, synthetic leather, fabric, paper and frosting, just can produce pile effects, neither affect coatingsurface mechanical property, in turn simplify production technique.
There is no this series products in the market, due to unique properties, again can Simplified flowsheet, existing Duo Jia manufacturing enterprise starts application, and should have good market outlook, manufacturing-oriented enterprise also has good economic benefit.
