Abstract
The invention provides a polyurethane sealing and repairing agent which comprises, on the basis of 100 parts by mass, 60 to 80 parts of an organosilicon modified waterborne polyurethane emulsion, 3 to 5 parts of synthetic wax, 3 to 5 parts of a feeling agent and 1 to 2 parts of a softener, with the balance being water. The above-mentioned components are uniformly mixed so as to obtain the polyurethane sealing and repairing agent. According to the invention, through combined usage of organosilicon modified waterborne polyurethane and synthetic wax, the polyurethane sealing and repairing agent which contains organosilicon and synthetic wax and has the advantages of bottom sealing, damage repairing and good hand feel is prepared.
Description
Technical field
The present invention relates to a kind of polyurethane sealing tonic, belong to chemical field.
Background technology
China skin source is abundant, but the amount of wounded or disabled skin is large, take full advantage of wounded or disabled skin, improve the quality of products and economic return, be pursuing a goal of leather producer always, but traditional matting and patching agent, solid content is low, film forming is crisp and hard, wounded or disabled skin Boardy Feeling after repairing although simple urethane resin is good with the bonding force of leather, is mended and is hindered weak effect.
Find after deliberation, polyurethane coating film is soft, good springiness, and strong with the bonding force of leather, organic silicone oil and synthetic wax have again excellent waterproof and light hides function, can effectively stop water paste to organize inner penetration to leather, and can not cause wounded or disabled epidermis face crisp hard.This patent is in conjunction with the advantage of aqueous polyurethane and organosilicon, synthetic wax, make to contain organosilicon, synthetic wax, and the collection back cover mend hinder, polyurethane sealing tonic that feel is better than one.
Summary of the invention
The purpose of this invention is to provide a kind of strong bonding force, have the polyurethane sealing tonic of better water tolerance and light covering effect.
For realizing above purpose, the prescription of polyurethane sealing tonic of the present invention is: in 100 parts of weight parts, and organic silicon modified aqueous polyurethane emulsion 60-80 part, synthetic wax 3-5 part, hand feeling agent 3-5 part, softening agent 1-2 part, the water of surplus.
Wherein the preparation process of acrylic ester modified water-soluble polyurethane emulsion is: at first with 2,6-tolylene diisocyanate (TDI), polyether glycol (N220), BDO (BDO), dimethylol propionic acid (DMPA) prepare performed polymer for raw material.In reaction process, add N-Methyl pyrrolidone to reduce viscosity.Then add organosilicon, through cooling, neutralization, emulsification, get organic-silicon-modified aqueous polyurethane emulsion.
Wherein the proportioning of performed polymer is: the mol ratio of TDI and N220, DMPA, BDO is 1.3:1-1.4:1, and BDO accounts for the 2%-3% of performed polymer total mass, and DMPA accounts for the 5%-6% of performed polymer total mass.
Wherein organic silicone oil accounts for 0.6% of performed polymer total mass.
The preparation technology of polyurethane sealing tonic of the present invention is: the water, synthetic wax, softening agent, the softening agent that add successively proportioning in container, fully stir, add again the organic silicon modified aqueous polyurethane emulsion, after stirring, leave standstill, obtain the polyurethane sealing tonic after the filtration.
The beneficial effect that the present invention produces is, this patent employing aqueous polyurethane and synthetic wax, organosilyl mutual supplement with each other's advantages, prepare the polyurethane sealing tonic, sealing tonic has the aqueous polyurethane soft film coating on the one hand, good springiness, the characteristics good with the leather associativity also have the excellent properties that organosilicon, synthetic wax waterproof and light hide.The polyurethane sealing tonic that makes of this paper can also cooperate with other auxiliary agent and carries out local back cover and mend and hinder on the other hand, also can be mixed with pigment paste mud and carry out the big area back cover and mend and hinder.
