Abstract
The invention relates to a production process flow and formula of novel TPU (Thermoplastic Polyurethane) synthetic leather. Vein colors of the surface of the novel TPU synthetic leather produced by using the invention are as rich as that of the conventional synthetic leather; hot melt adhesive on the back is protected by a plastic thin film; during the use, after the plastic film is removed, the unique hot melt adhesive is combined with a high-frequency hot-cutting process and can be perfectly combined with the surfaces of a mesh, a woven fabric and ordinary synthetic leather, so that the quality is more stable, the sense of quality is stronger and the labour-intensive sewing process during the use of the conventional synthetic leather is reduced; meanwhile, no solvent needs to be used in the hot melt jointing process, so that the pollution to the environment is reduced.
Description
Technical field
The present invention relates to a kind of synthetic leather technological process of production and prescription, particularly a kind of new TP U synthetic leather technological process of production and prescription.
Background technology
Current, the synthetic leather product is just becoming following fashion trend, is widely used in every field such as clothes, case and bag, suitcase, furniture, footwear.General PU synthetic leather normally is laminated to the lamellar product that compositions such as nonwoven, looped fabric, weaving cloth or woven cloth form by polyurethane resin composition, its structure comprises base cloth and attached to the polyurethane resin top layer on the base cloth, the top layer is mainly risen to decorate and outward appearance is reached and imitated a natural skin effect of removing from office; General synthetic leather in use all adopts to be sewed up or solvent lamination technology, and at serious day by day present of recruitment famine, labor-intensive sewing process is unfavorable for the development of enterprise; And the glue that conventional laminating type adopts contains organic solvent, is unfavorable for the protection of environment.The objective of the invention is to develop a kind of new TP U synthetic leather, make synthetic leather adopt seamless applying technology in using, avoided the environmental pollution that solvent evaporates caused after solvent uses again.
Summary of the invention
Technical problem to be solved by this invention is to overcome above technical bottleneck, and a kind of new TP U synthetic leather technological process of production and prescription are provided.
For solving the problems of the technologies described above, the present invention realizes as follows:
A kind of new TP U synthetic leather technological process of production of the present invention and prescription, it is characterized in that this technological process of production comprises the steps: at first to choose dystectic TPU film and more low-melting hot-melt adhesive granules, again hot-melt adhesive granules is heated to the liquid condition of complete fusion, evenly be coated on the TPU film back side, to be cooled plaing to a certain degree back compound upward PE plastic foil protected the PUR effect, makes TPU synthetic leather half product; Make new TP U synthetic leather through dry method PU surfacing process again.
Good effect of the present invention: a kind of new TP U synthetic leather technological process of production of the present invention and prescription, the new TP U synthetic leather surface pattern color of utilizing the present invention to make is the same with conventional synthetic leather abundant.Back side PUR is protected by plastic sheeting, in use remove plastic foil after, exclusive PUR is in conjunction with the high frequency heat cutting process, can be with screen cloth, weave cotton cloth and common synthetic leather surface perfect adaptation, quality is more stable, product texture is stronger.Reduce the labour-intensive sewing process in the conventional synthetic leather use, in the hot melt attaching process, need not to use any solvent simultaneously, reduced environmental pollution.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the half-finished technological process of production figure of TPU of the present invention
Fig. 2 is a TPU finished product leather process chart of the present invention
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of new TP U synthetic leather technological process of production of the present invention and prescription, its technological process of production is:
Phase I: the technological process of production of TPU semi-finished product base
Select for use fusing point to be higher than 180 ℃ TPU film and the hot-melt adhesive granules of fusing point about about 100 ℃, hot-melt adhesive granules is heated to complete molten condition, evenly be coated on the TPU film back side, be cooled to the compound 0.2-0.3mm thickness PE plastic foil of going up in about about 60 ℃ backs and play the effect of protection PUR, make TPU synthetic leather half product; The thermosol consumption is 50-100g/m
2
Second stage: the technological process of finished product leather
Use the PU resin dissolves in DMF and MEK solvent the dry method lining, preparation dry method surface layer PU mixed liquor; Select for use the dry method adhesive linkage of adhesion strength excellence to use the PU resin dissolves in the MEK solvent, preparation dry method adhesive linkage mixed liquor; With the blade coating mode with dry method lining mixed liquor with (120～180) g/m
2Consumption is coated on the release liners, through 60～80 ℃ heated-air drying, cools off 1～2 minute, gives leather surface lines and color; On epidermal area, apply (150～200) g/m again
2Mixed solution of adhesive layer, prebake after 1 minute is sticked the semi-finished product base, control patch pressure is about 4～6kg/cm2; Carry out release liners after 5 minutes with 60～80 ℃ of heated-air dryings and peel off, the product after peeling off is the finished product leather.Line speed is controlled at 6-8/min.
