Abstract
The invention relates to a method for manufacturing polyurethane leather for high-durability, high-wear-resistance and flame-retardant sofa furniture. The polyurethane leather for the high-durability, high-wear-resistance and flame-retardant sofa furniture is particularly manufactured by the following steps of: processing synthetic leather on raising base cloth; and performing a synthetic leather process on a polycarbonate type polyurethane paste material according to a specific formula ratio. The product of the invention has the performance such as high durability, high wear resistance, flame retardancy and the like, improves the durability and the service performance and has broad market prospect.
Description
Technical field
The present invention relates to the manufacturing approach of a kind of high-durability, high-wear-resistance and flame-retardant sofa furniture with Synthetic Leather.
Background technology
Artificial leather, synthetic leather industry development are rapid in recent years; The synthetic leather product is widely used in people's various fields in life; Monopolize but be almost external producer with the Synthetic Leather series products as the high-durability, high-wear-resistance and flame-retardant sofa furniture of its high-end product, and along with the developing rapidly of domestic market, increasing to the high-end synthetic leather market demand; Our company is according to the market demand; Through continually developing research, be chosen in and apply special kinds polyurethane resin and functional material blend above the raising base cloth, and through technological innovation make that product has that height is durable, high abrasion, performance such as fire-retardant; Improve the durability and the serviceability of product, had extensive market prospects.
Summary of the invention
The invention discloses a kind of manufacturing approach with high durable, high abrasion, flame-retardant sofa furniture with leather.
For the present invention that achieves the above object has adopted following technical scheme:
The present invention passes through: the polyurethane coating resin of in the step (a) and (b), selecting for use is a polycarbonate type resin; In the polyurethane slurry, add various functional materials such as fire-retardant, wear-resisting and be used the synthetic leather processing technology; Make the synthetic leather of manufacturing have functions such as permanent fire retardant, high durable, high abrasion, the synthetic leather in the step (b) is placed in the rub barrel kneading again can obtains a kind of high-durability, high-wear-resistance and flame-retardant sofa furniture and use the Synthetic Leather finished product.
Description of drawings
Below in conjunction with accompanying drawing the present invention is explained further details.
Accompanying drawing 1 is a wet coated technology Synthetic Leather process chart;
Accompanying drawing 2 is a dry coating Synthetic Leather process chart;
Accompanying drawing 3 is rubbed the leather process chart for post processing.
The specific embodiment
Shown in figure (1); This high-durability, high-wear-resistance sofa furniture uses the wet-method synthetic leather technological process of leather to be: raising base cloth → soak contains the 0-50%DMF aqueous solution → base cloth moisture percentage adjustment → wet coated → solidify → wash → drying and shaping, can obtain high-durability, high-wear-resistance and flame-retardant sofa furniture and use the Synthetic Leather wet half-finished product.
Shown in figure (2); It is (two skill in using a kitchen knife in cookery) that this high-durability, high-wear-resistance and flame-retardant polyurethane sofa furniture uses the dry process flow process of leather: the surface layer slurry that on release liners, is coated with one deck suitable thickness; Advancing baking oven suitably dries; Be coated with one deck adhesive linkage again and stick, get into to peel off after the oven for drying and get final product to such an extent that a kind of high-durability, high-wear-resistance and flame-retardant sofa furniture is used the Synthetic Leather semifinished or finished goods like figure (1) flow process manufacturing wet method base material.
Shown in figure (3), the semi-finished product that will shown in figure (2), make after special process is handled, put in the rub barrel kneading get final product manufactured goods.
