Abstract

A kind of method for producing environment-friendly type water prick nonwoven cloth shoe lining leather, comprises the following steps：The first step：45g to 80g spunlace non-woven cloth is impregnated in the mixed liquor of aqueous polyurethane and aqueous color paste；Second step：Again through drying, drying：3rd step is then by release liners method and aqueous polyurethane surface layer, and non-solvent foamed polyurethane bottom is combined, the spun laced fabric shoe lining leather of a variety of colors and decorative pattern needed for obtaining.100 parts of the 30% aqueous polyurethane volume ratio of material proportion, 100 parts of water, mill base is some.Modified technique of the present invention：Spun laced fabric is impregnated with（Aqueous PU）Dry semi-finished product laminating maturation（Without discharge）Finished product；The non-solvent foamed PU coatings laminating maturation of the aqueous PU coatings drying of release liners（Without discharge）Finished product.The present invention is impregnated with coloring using aqueous polyurethane, and non-solvent foamed polyurethane does the processing method that bed material, aqueous polyurethane do surface layer.It is not added with any organic solvent, it is ensured that the environmental protection of production process and final finished.

Description

A kind of method for producing environment-friendly type water prick nonwoven cloth shoe lining leather
Technical field
The present invention relates to the preparation method of spunlace non-woven cloth shoe lining leather.
Background technology
Former technique：Spun laced fabric ----give impregnation（PU and DMF）--- give solidification（Water）--- coating（PU and DMF）----solidification （Water）--- washing --- drying（1st, waste water DMF---DMF reclaims 2, semi-finished product --- laminating --- drying --- -- 1. waste gas -- DMF Reclaim 2. finished product）.
Release liners --- coating（PU and DMF, MEK）--- give drying ----laminating --- drying（1st, waste gas ----DMF is reclaimed 2nd, finished product）Using the organic solvent of harmful effumability, substantial amounts of waste water is produced, waste gas, technological process is complicated, high energy consumption, Finished product residual volatile organic matter is exceeded, and production process is seriously polluted.
The content of the invention
The present invention provides one kind and is not added with any organic solvent, it is ensured that production process and final finished are all arranged without waste gas, waste water The method for the production environment-friendly type water prick nonwoven cloth shoe lining leather put.
The present invention is achieved by the following technical solution：A kind of side for producing environment-friendly type water prick nonwoven cloth shoe lining leather Method, it is characterised in that it comprises the following steps：The first step：By 45g to 80g spunlace non-woven cloth in aqueous polyurethane and aqueous color Impregnated in the mixed liquor of slurry；
Second step：Again through drying, drying：
3rd step is then by release liners method and aqueous polyurethane surface layer, and non-solvent foamed polyurethane bottom is combined, needed for obtaining A variety of colors and decorative pattern spun laced fabric shoe lining leather.
The oven for drying temperature sets 80 DEG C -- and 140 DEG C.
100 parts of the 30% aqueous polyurethane volume ratio of material proportion, 100 parts of water, mill base is some.
Modified technique of the present invention：Spun laced fabric ----impregnation（Aqueous PU）--- ----semi-finished product ----laminating --- are ripe for-drying Into（Without discharge）----finished product；Release liners ----aqueous PU coatings --- -- drying --- -- non-solvent foamed PU coatings --- patch Close ----maturation（Without discharge）--- -- finished product.The present invention is impregnated with coloring using aqueous polyurethane, and non-solvent foamed polyurethane does bottom The processing method that material, aqueous polyurethane do surface layer.It is not added with any organic solvent, it is ensured that the green ring of production process and final finished Protect.
Embodiment：
Embodiment 1：Produce 0.6mm and imitate the soft shoe lining leather of sheepskin line：
1st, 60g spun laced fabrics be impregnated with aqueous PU, dried, through oven for drying, rolling after cooling, temperature sets 100 DEG C -- 140 DEG C breadth control 142cm material proportions 30% are aqueous PU100 parts, and 100 parts of mill bases of water are some.
2nd, sheepskin line release liners are imitated -- aqueous PU coatings（15）-- drying（80--140℃）--- solvent-free bed material coating （15）--- dry（80--100℃）--- being fitted with spun laced fabric --- maturation（100--130℃）--- winding --- is peeled off --- in cooling （Finished product）；
Wherein aqueous proportioning;30% is soft PU100 parts, and 50 parts of water, thickener 0.5% solvent, 0.2% mill base is some.
Wherein solvent-free material proportioning：Soft solvent-free two-component PU100 parts, catalyst 0.3%, mill base is some.
Embodiment 2：Produce 0.7mm and imitate the ventilative shoe lining leather of pigskin line；
1st, using 70g spun laced fabrics, other are with reference to above；
2nd, using pigskin line release liners, aqueous PU is coated with 20, and finished product is punched, and other are with reference to above.
Embodiment 3：Produce hard water suction footwear in 0.8mm and scald bottom
By 80g spun laced fabrics, other are with reference to above, and hard absorbs water aqueous PU and solvent-free two-component PU in use, and other are with reference to upper Face.
