Abstract

The utility model belongs to the technical field of the synthetic leather and specifically relates to a synthetic leather is felt to high rerum natura fine hair, including super fine end base, the dry process bottom of coating on super fine end base, the dry process middle level of coating on the dry process bottom, the dry process surface course of coating on the dry process middle level, the three editions process colors on the dry process surface course of coating, super fine fine hair sense layer on three editions process colors coats. The defect that the synthetic leather texture is single, the colour is poor is felt to the traditional fine hair of this synthetic leather change, provides one kind and more can satisfy the synthetic leather is felt to high rerum natura fine hair that people feel strong, have a lot of color solid texture effect high rerum natura, the fine hair of break and pattern demand.

Description

A kind of high physical property velvet-feel synthetic leather

Technical field

The utility model relates to synthetic leather field, especially a kind of high physical property velvet-feel synthetic leather.

Background technology

At present, on market, popular velvet-feel synthetic leather mainly contains sheep bar synthetic leather, ox bar synthetic leather and surperficial skinfeel synthetic leather, in physical property, these products all also exist certain defect, if sheep bar synthetic leather is in scratch resistance and hydrolysis is not good, the ox bar single third dimension of synthetic leather lines bad surperficial its velvet of skinfeel synthetic leather is not good.For making up above defect, I takes charge of the velvet-feel synthetic leather of a kind of novel high physical property of special research and development.

Utility model content

Technical problem to be solved in the utility model is the defect changing single, the colour-difference of traditional velvet-feel synthetic leather texture, provides a kind of and more can meet the high physical property velvet-feel synthetic leather that people are strong to the high physical property of break and patterning requirement, velvet, have repeatedly colour solid grain effect.

For solving the problems of the technologies described above, the utility model realizes in the following way: one described in the utility model high physical property velvet-feel synthetic leather comprises base of the super fine end, be coated in the dry method bottom on base of the super fine end, be coated in the dry method middle level on dry method bottom, be coated in the dry method surface layer on dry method middle level, be coated in three editions process colors on dry method surface layer, be coated in the super fine velvet layer on three editions process colors.

Described dry method bottom is mixed by PU polyurethane resin, dimethyl formamide, toner and bridging agent, and the mixed proportion of described PU polyurethane resin, dimethyl formamide, toner, bridging agent is 100: 30-40: 5-10: 3; Every square meter grammes per square metre 230g-270g of described dry method bottom, viscosity is 8000-10000cps/25 DEG C.

Described dry method middle level is mixed by PU resin, dimethyl formamide and toner, and the mixed proportion of described PU resin, dimethyl formamide and toner is 100: 50-60: 10-15; Every square meter grammes per square metre 180g-220g in described dry method middle level, viscosity is 5000-6000cps/25 DEG C.

Described dry method surface layer is mixed by PU resin, dimethyl formamide and toner, and the mixed proportion of described PU resin, dimethyl formamide and toner is 100: 80: 10-15; Every square meter grammes per square metre 140g-160g of described dry method surface layer, viscosity is 1500-2000cps/25 DEG C, and the coating thickness of described dry method surface layer is 0.15mm.

Every square meter grammes per square metre 50g-60g of described super fine velvet layer, viscosity is 600-800cps/25 DEG C.

Good effect of the present utility model: a kind of high physical property velvet-feel synthetic leather described in the utility model provides a kind of more can meet the high physical property velvet-feel synthetic leather that people are strong to the high physical property of break and patterning requirement, velvet, have repeatedly colour solid grain effect, between each layer of synthetic leather, bonding firmly, synthetic leather finished product good hand feeling, third dimension of patterns is pure, quality is fine and smooth, good permeability, can be widely used in the fields such as motion leather, sofa artificial leather, ball leather.

Detailed description of the invention

Fig. 1 is structural representation of the present utility model

In figure: 1, dry method surface layer 2, dry method middle level 3, dry method bottom 4, base of the super fine end 5, three editions process colors 6, super fine velvet layer

As shown in Figure 1, one described in the utility model high physical property velvet-feel synthetic leather comprises base of the super fine end, be coated in the dry method bottom on base of the super fine end, be coated in the dry method middle level on dry method bottom, be coated in the dry method surface layer on dry method middle level, be coated in three editions process colors on dry method surface layer, be coated in the super fine velvet layer on three editions process colors.

Production process of the present utility model comprises following technological process:

1) by R-51 type release liners or dark lichee line type release liners, be coated with one deck dry method surface layer by a coating head, coating clearance is at 0.15mm, and the every square meter grammes per square metre of coating weight is at 150 ± 10g, and viscosity controls at 1500-2000cps/25 DEG C;

2) will be coated with the release liners of dry method surface layer through No. two coating heads, in its surface coating one deck viscosity in the dry method middle level of 5000-6000cps/25 DEG C, coating weight control is at every square meter grammes per square metre 200 ± 20g;

3) by scribble dry method surface layer, dry method middle level release liners by No. three coating heads, coating one deck viscosity is at the dry method bottom of 8000-10000cps/25 DEG C, and coating weight control is at every square meter grammes per square metre 250 ± 20g;

4) dry method bottom is directly sticked the base post-drying of the super fine end after fine grinding, bake out temperature controls, at 80-130 DEG C, to improve bake out temperature gradually, and after oven for drying 5-6 minute, release liners is peeled off in cooling;

5) after cooling, last layers are applied with velvet through three printing machines by dry method surface layer, color and texture are different from three editions process colors of dry method surface layer, and the printing decorative pattern of three editions process colors must have corium grain effect, and after printing, semi-finished product are made in cooling oven dry;

6) by semi-finished product through impregnation directly coating head, the super fine velvet layer of coating one deck hairiness velvet, viscosity controls at 600-800cps/25 DEG C, coating weight control is at every square meter grammes per square metre 50g-60g, the colouring discrimination of super fine velvet layer is in dry method surface layer and three editions process colors, form three layers of distinct look with dry method surface layer and three editions process colors, present the lichee line that third dimension is strong, the synthetic leather velvet made is strong, skinfeel is strong.

Raw material needed for above production technology must be acidproof, alkaline-resisting, cold-resistant polyurethane, will ensure dry way process free of pinholes in process of production, without concave point simultaneously.Directly be coated with in technique in post processing and have requirement to toner addition, if toner content will cause dry wet rubbing COLOR FASTNESS lower than 3.5 grades more than 8%, that will need in fixation skin feel treatment agent.
