A production method for PU furniture leather, comprises the following steps:
(1) aluminium chloride, allicin, fenugreek gum, trehalose and sodium alginate are added in suitable quantity of water, 800-1000r/min stirs 15-30min, adds sodium carboxymethylcellulose, and 600-800r/min stirs 5-10min, be ground to 100-200 order after freeze drying, obtain active powder;
(2) first dimethyl formamide is added in a reservoir, add pine needle meal, alfalfa meal, active powder and modified additive again, mill base and polyurethane resin is added fully stir 10-20min at 25-40 DEG C after, all the other raw materials are added after stirring, 800-1000r/min stirs 5-10min, vacuum defoamation 30-60min, 50-100 order filters, and obtains PU slurry;
(3) base cloth is soaked, adopt painting cutter cladding process that PU slurry is coated in Ji Bushang equably, send into coagulating basin and solidify, then through washing, drying, after surface treatment, get product.
Advantage of the present invention is:
1. Bound moisture gel technique, plays the water imbibition effect that it is superior, makes product have good absorbent ventilate performance and outward appearance, the feel of emulation, and effectively improve comfort level and the emulation property of PU synthetic leather, the performance of synthetic leather is closer to natural leather;
2. there is the features such as soft, fire-retardant fireproof, safety and low toxicity, be applicable to make furniture.
