Abstract
The invention discloses a PU decorative film surface treating agent and a method for treating a PU decorative film by using the agent. The surface treating agent comprises polyester polyol, polycaprolactone glycol, dihydric alcohol, diphenylmethane diisocyanate, dimethyl formamide, butanone, toluene, isopropanol, matting powder and an additive. In preparation, the above-mentioned materials are successively subjected to procedures consisting of mixing, stirring, dilution, grinding and filtering so as to obtain the PU decorative film surface treating agent. The method for treating the PU decorative film comprises a first step of compounding, a second step of embossing and matting, a third step of coating and a fourth step of curing and drying. The invention has the following advantages: after polymerization of polyester polyol, dihydric alcohol, polycaprolactone glycol and the like and usage of the matting powder, the PU decorative film surface treating agent has extremely low glossiness, so the PU decorative film coated by the treating agent also has such ultra-matte luster; when the treating agent obtained after polymerization coats the decorative film, the surface of the decorative film has good scrape resistance and better hand feeling.
Description
Technical field
The invention belongs to decorating film technical field, especially relate to a kind of method of PU decorating film surface treatment agent and processing PU decorating film thereof.
Background technology
Dumb light PU decorating film is applied in the products such as home decoration, household electrical appliances, furniture, automotive trim mostly at present, and existing PU decorating film is to be formed by the PU pad pasting laminating of multilayer different qualities, in order to reach the effect of dumb light, conventionally at surface label unification layer matt film, reach the object of delustring by the high temperature embossing of fitting again, though this method has certain extinction effect, still be still difficult to reach the luster effect of super dumb light, and its surface is comparatively coarse, feel is poor; Because it is applied in daily life, usually can run into various wipings, slight impact and wearing and tearing, so scratch resistance is had relatively high expectations and current PU decorating film scratch resistance is all very general, be therefore necessary to be improved.
Summary of the invention
The object of the invention is the deficiency existing for above-mentioned prior art, provide a kind of dumb light and feel better and the PU decorating film surface treatment agent that scratch resistance can be used for a long time and the method for processing PU decorating film thereof.
To achieve these goals, the technical solution adopted in the present invention is: a kind of PU decorating film surface treatment agent, and it is made up of following component by mass fraction: 10～15 parts of polyester polyols; 1～3 part of PC glycol; 1～3 part of dibasic alcohol; 3～7 parts of diphenylmethanediisocyanates; 15～25 parts of dimethyl formamides; 15～25 parts of butanone; 15～20 parts of toluene; 8～12 parts of Virahols; 3～7 parts of flatting silicas; 6～10 parts of additives; When preparation, drop in reactor and mix by polyester polyol, dibasic alcohol and with dimethyl formamide, butanone, toluene that volume pump measures total amount 2/3; Add reactor to mix with mixed solution PC glycol again; Drip the diphenylmethanediisocyanate dissolving with water-bath; After dropwising, be warming up to 70～90 ℃ of repolymerization reactions 4～6 hours; After polymerization completes, carry out again coolingly, add dimethyl formamide, butanone and toluene to dilute with volume pump again after cooling, until the viscosity of polymkeric substance reaches normal viscosity; After having diluted, then in polymers soln, add flatting silica, additive and Virahol mixing and stirring; After having mixed, entering shredder grinds; Sampling detects, until stop after qualified grinding; Mixture after grinding is filtered by strainer; After filtration completes, first keep in to temporary storage tank, then weigh and detect, adjust viscosity and make it reach standard.
12 parts of described polyester polyols; 2 parts of PC glycol; 2 parts of dibasic alcohol; 5 parts of diphenylmethanediisocyanates; 20 parts of dimethyl formamides; 20 parts of butanone; 17 parts of toluene; 10 parts of Virahols; 5 parts of flatting silicas; 8 parts of additives.
Described additive comprises organic tin catalyzer, Microcrystalline Cellulose, vegetables oil, wax powder, antioxidant and sparklet.
PU decorating film surface treatment agent is processed a method for PU decorating film, and its processing step is as follows:
A, get any two or three in PU basement membrane, PU printing mesopelagic layer and PU delustring facial mask and carry out successively compoundly, obtain PU composite membrane;
B, the PU composite membrane obtaining is taken turns and carried out embossing delustring processing by dumb light;
C, PU decorating film surface treatment agent is coated on the surface of PU composite membrane;
D, by coating after PU composite membrane be cured dry.
While carrying out embossing delustring in described step b, the glossiness of PU composite membrane is controlled between 30～50 ℃.
When described step c is coated with, coating thickness is controlled between 0.1～0.3mm.
Described after steps d completes, the curing oven that PVC composite membrane is placed in to 100～120 ℃ carries out maturation process, and the PU composite membrane after slaking and backing material are fitted and changed line.
The advantage that compared to the prior art the present invention had is: after the polyreactions such as polyester polyol of the present invention, dibasic alcohol and PC glycol and flatting silica can allow PU treatment agent there is extremely low glossiness, while being allowed to condition at coating, allow decorating film there is equally this super dumb light gloss; Treatment agent after polymerization while being coated on decorating film, can allow its surface there is good scratch resistance and feel better.
