Abstract
The invention relates to a kind of environment-friendly high performance PU synthetic leather which belongs to burn-retarding synthetic leather domain. The invention uses the aquosity polyurethane as the material, the phosphide fire-fast plasticizer as the retardant; it also contains the accessories such as modifier and dispersing agent; the invention has solved the serious environment-protection problem in leather producing and the eight poisonous and toxic elements in the synthetic leather has satisfied the European standards. By adding organosilicon dry lubricant prescription in the invention, the leather has many effects such as clean, dry, lubricate, sterilization, mould proof, water proof, moisture absorption proof and separation proof; it has more notable dermis simulating effect.
Description
Technical field
The present invention relates to flame retardant resistance synthetic leather field, refer in particular to a kind of PU synthetic leather of environment-friendly type high performance, provide the preparation method of this PU synthetic leather simultaneously.
Background technology
In the present domestic synthetic leather production process, usually the PU resin that adopts organic solvent type is as the basic unit that produces the leather product and the basic raw material of surface layer, such PU resin passes through toluene, dimethylbenzene, acetone, butanone, ethyl acetate, dimethyl formamides etc. make with solvent polymerization method as primary solvent, these organic solvents all are objectionable impuritiess, according to statistics, article one, synthetic leather production line daily need consume the solvent-borne type PU resin about 10 tons, wherein accounting for the total consumption of solvent-borne type PU resin more than 60% is solvent, though about 85% solvent is recovered in the wet production line, but still have about 15% in the wet production line, 95% solvent can't reclaim in the dry process production line, to be discharged into the river of periphery and day aerial by water and air, environment that certainly will the severe contamination locality, the production of giving people, life, the public's life and health constitutes significant threat.
On the other hand, in homemade synthetic leather production process, inorganic materials such as employing antimonous oxide are as fire retardant, can not improve the plasticity-of leather products, flame retardant effect is not best, has brought heavy metal element antimony etc. simultaneously in leather products, has influenced the environmental protection index of product.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of environment-friendly type high-performance PU synthetic leather that can not cause environmental pollution, heavy metal free element to bring product into is provided, main innovation is with the aqueous polyurethane to be raw material, with the phosphide plasticizer of anti-the combustion is fire retardant, mainly implement like this: environment-friendly type high-performance PU synthetic leather is characterized in that the weight proportion of component is:
100 parts of aqueous polyurethanes
The phosphide plasticizer of anti-combustion 0.1-0.6 part
Properties-correcting agent 2-7 part
Dispersion agent 1-7 part
Wherein the phosphide plasticizer of anti-the combustion is meant the one or more combination thing of ammonium polyphosphate, melamine phosphate, aluminum phosphate, trimagnesium phosphate, zinc phosphate, phosphoric acid ester derivant.
Properties-correcting agent is that phosphoric acid ester is that properties-correcting agent, silicon are that properties-correcting agent, titanic acid ester are the one or more combination thing of properties-correcting agent;
Dispersion agent is that acrylic acid series dispersion agent, silicon are that dispersion agent, fluorine are the one or more combination thing of dispersion agent.
The present invention produces high-grade car PU synthetic leather by selecting for use aqueous polyurethane to substitute traditional solvent borne polyurethane, solved serious environmental issue in the solvent-borne type synthetic leather production process effectively, made the big poisonous and harmful element of eight in the synthetic leather product reach European standard simultaneously.
The present invention can play dry and comfortable, lubricious, sterilization, mildew-resistant, anti-hydrolysis, anti-moisture absorption, anti-effect such as separate out in order to make leather, improve the over-all properties of leather, reach the into physical index of PU synthetic leather, make its skin emulation effect more remarkable, be added with the dried lubrication prescription of organosilicon in the component in addition, the dried lubrication prescription addition of the organosilicon of 100 parts of aqueous polyurethanes is 0.5-1.5 part.
The preparation method of this environment-friendly type high-performance PU synthetic leather mixes high-speed stirring with above-mentioned each component by proportioning to leave standstill 12-24 hour after evenly.
Product integrated performance index height of the present invention, nontoxic, tasteless, fire-retardant and possess anti-hydrolysis, anti-function such as separate out, do not go mouldy, no environmental protection problem in the production, skin emulation effect is remarkable, complete alternative corium uses, and is a kind of environmental-friendly leather, after testing, actual fire-retardant value is better than EN71-2 vertical combustion index request greatly, the product elongation, tears load and is better than national standard.
