Description

A kind of superfine fiber polyurethane imitation leather face fabric for automobile seat of soft abrasion-resistant and preparation method thereof
Technical field
The present invention relates to synthetic leather field of material technology, superfine fiber polyurethane imitation leather face fabric for automobile seat particularly relating to a kind of soft abrasion-resistant and preparation method thereof.
Background technology
With rapid development of economy, the living standard of people is more and more higher, and the requirement to quality of life also gradually steps up.The demand of leather and fur products is increasing, and class is also more and more higher.China's population multiple resource is few, corium limited source, it is difficult to meet the demand of people.Nowadays interior leather for automobiles has been widely used in the inside gadget of riding vehicle, carrier.With growth in the living standard, people are also more and more higher to the quality requirement of interior leather for automobiles, environmental requirement, comfort requirement.Automotive trim is removed from office, and optimal selection is corium, but corium pollutes environment seriously in himself production process, and content of beary metal easily exceeds standard, and in inside gadget process, lumber recovery is relatively low, and its cost is high, it is difficult to accepted by low and middle-grade passenger cars；And environmental protection is gradually paid attention to by people, advocating environmental protection and energy saving, today of sustainable development, people also begin to develop leather fabric to replace animal's leather, to avoid the injury to wild animal and the destruction to natural environment.
At present, the positions such as automobile door plate, face fabric for automobile seat, instrument board, compartment inwall, Roof of vehicle, steering wheel cover, the main material using non-weaving cloth etc. to be combined with polyvinyl chloride, polyurethane etc..There is the defects such as Boardy Feeling, comfortableness difference, loss of properties on aging, smell weight, the easy migration precipitation of plasticizer in common polyvinyl chloride dermatine, so the common PVC artificial leather in current automotive trim is gradually replaced by polyurethane (PU) synthetic leather.And the production of Synthetic Leather uses solvent type production system, the use of a large amount of organic solvents, not only pollute environment, and seriously compromise the health of people.With the reinforcement of environmental regulation and people's environmental consciousness, waterborne polyurethane synthetic leather technology becomes the study hotspot in this field.
Therefore, sense of touch as one has is manufactured with corium, comfortable equally and environmentally friendly, physical properties is identical with corium or exceedes the research and development task that genuine imitation leather interior leather for automobiles becomes artificial leather production field.
Content of the invention
The object of the invention is contemplated to make up the defect of prior art, superfine fiber polyurethane imitation leather face fabric for automobile seat providing a kind of soft abrasion-resistant and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of superfine fiber polyurethane imitation leather face fabric for automobile seat of soft abrasion-resistant, it is prepared by the raw materials in: polyamide-675-77, alkali soluble polyester chip 25-26, concentration is that 20% sodium hydroxide solution is appropriate, aqueous polyurethane 50-53, nano-sized magnesium hydroxide 5-6, APP 3-4, neopelex 5-6, rutile titanium stock white 3-4, water is appropriate, polyvinyl alcohol 0.7-0.8, epoxysilicone 1-1.2, triethylamine 0.8-1, nano silicon oxide 4-5, nano aluminium oxide 3-4, absolute ethyl alcohol is appropriate, silane coupler kh5500.7-0.8, bamboo carbon powder 2-3, AEO 0.7-0.9, aqueous color 6-7.
The superfine fiber polyurethane imitation leather face fabric for automobile seat of a kind of soft abrasion-resistant according to claims 1, is prepared from by following concrete grammar:
(1) it is dried respectively with alkali soluble polyester chip after polyamide-6 being cut into slices, control water content is less than 1%, carry out spinneret by the melted fabric of island-in-sea type spinning pack that enters of respective single extruder type spinning machine stirring respectively, the tow obtaining through drawing-off (being drawing-off 3.5 times at 75 DEG C in temperature), oil, wind, be dried (drying 5-10 minute for 55-65 DEG C), cut off (control fibre length is 50-55mm, and fiber number is 5-7dtex) and obtain composite superfine staple；Composite superfine staple use after shredding is cotton carding machine be carded to single layer fibre net, it is then passed through cross lapping machine and form composite bed fleece, puncture on needing machine again, finally utilize bead cutter cutting neat, carry out thermal contraction fixation under conditions of 120-140 DEG C, obtain superfine fiber synthetic leather base cloth；
(2) neopelex is dissolved in the water of 5 times amount, add nano-sized magnesium hydroxide, rutile titanium stock white APP and the aqueous polyurethane of half amount, it is heated to 50 DEG C, after stirring 15 minutes with the speed of 500 revs/min, speed with 1000 revs/min stirs 10 minutes again, obtain nano modified material emulsion, put it in dipping tank, then above-mentioned superfine fiber synthetic leather base cloth is impregnated wherein, through roll pressed after being sufficiently impregnated with, taking out base fabric puts in baking oven, at a temperature of 120-130 DEG C fully dry, obtain fire-retardant anti-solarization modified superfine fiber synthetic leather base cloth；
