The preparation method of a kind of organosilicon polychrome leather, comprises the following steps:

A. being coated in release paper or mould release membrance by the Silica gel coatings of primer, laminating base material (1), at 80～200 DEG C At a temperature of vulcanize 1～30 minute, peel off release paper or mould release membrance, prepare base material (1) and primer layer (2)；

B. primer layer (2) surface is through the hopper equipped with mottle layer sizing, and some mottles of adhesive tape on primer layer, through sulfur Change, obtain mottle layer；

C. transparent area glue-line sizing material is coated on release paper or mould release membrance, the mottle layer obtained in laminating step b

(3), vulcanize 1～30 minute at a temperature of 80～200 DEG C, peel off release paper or mould release membrance, can be prepared by organic Silicon polychrome is removed from office.

Preferred: in the upper method coating mottle layer of primer layer (2) in described step b: contain coloured in hopper Speckle layer sizing, and deflector roll is arranged at above hopper, by primer layer (2) through deflector roll and hopper, can be by color Speckle layer sizing is coated on primer layer (2), structure such as Fig. 2.

A kind of organosilicon polychrome leather of the present utility model, compared to existing technology, has the advantages that

This utility model prepare organosilicon bicolor leather is the most antifouling, ventilative, high-low temperature resistant, hydrolysis, ageing-resistant, and And color desktop, color fast, its preparation method is simple and environmentally-friendly.

Detailed description of the invention

Accompanying drawing discloses the structural representation of one preferred embodiment of this utility model without limitation, below with reference to accompanying drawing Explain the technical solution of the utility model.

Embodiment 1

A kind of organosilicon polychrome leather of the present embodiment, as it is shown in figure 1, include that composite joint is put the most successively together Base material 1, primer layer 2, mottle layer 3 and transparent area glue-line 4.Base material 1 is super fine for 0.8mm thickness.

Composition and weight proportion that described transparent area glue-line 4 uses are as follows:

Composition and weight proportion that described mottle layer 3 uses are as follows:

Composition and weight proportion that described primer layer 2 uses are as follows:

A. being coated in release paper by the Silica gel coatings of primer, THICKNESS CONTROL is at 0.15mm, and laminating 0.8mm thickness is super fine, Vulcanize 5 minutes at a temperature of 130 DEG C, peel off release paper, prepare base material (1) and primer layer (2)；

B. primer layer (2) surface is through the hopper equipped with mottle layer sizing, and some mottles of adhesive tape on primer layer, through 130 DEG C sulfuration 5 minutes, obtain mottle layer；Vulcanize 1～30 minute at a temperature of 80～200 DEG C.

C. transparent area glue-line sizing material being coated on release paper, THICKNESS CONTROL obtains in 0.05mm laminating step b Mottle layer (3), vulcanizes 10 minutes at a temperature of 130 DEG C, peels off release paper, can be prepared by organosilicon polychrome leather. Difference between each glue-line of embodiment 2 to 9 and each comparative example see table, and embodiment is same as in Example 1.

The organosilicon synthetic leather obtaining embodiment 1-9 and comparative example 1-4 carries out following experiment:

1. wearability

Test by the regulation of QB/2726-2005, use CS-10 emery wheel, loading 1000g, test revolution 1000 turns Stamp wearability evaluation criteria:

1 grade entirely without

2 grades have residual or the marking

3 grades can resolution patterns or word

4 grades of patterns or word are clear

5 grades of patterns or word are unchanged

2. scoring resistance

Repeatedly swipe 10 times at leather surface by the identical dynamics of unitary coin, erasure will be scraped compared with not scraping erasure

A: surface is unchanged

B. surface pattern change is inconspicuous

C: surface pattern obscures

Can't see lines the most completely

3. pliability

With reference to CN100400678 " leather coating composition, coating process and application leather ", grade is as follows:

A is the most soft

B is soft

C is medium

D is hard

E is very rigid

4. smooth feeling

A is dry and comfortable smooth

B is smooth

C on-slip.

5. soil resistance

Ball pen ink is sprinkled upon on leather, contrasts after clearing up with ethanol after 24 hours:

5 grades: inviolateness remains

4 grades: slightly stain residual

3 grades: some stains remain

2 grades: many stain residuals

1 grade: dirty.

The enforcement data of each embodiment and comparative example and test data such as table 1 time:

Table 1

Above example and comparative example with regard to the thickness of transparent area glue-line and primer layer to the wearability of leather, scoring resistance, soft The impact of two-color effect is contrasted by softness, the impact of smooth feeling and mottle layer.1. transparent area glue-line provides for leather Smooth feeling, wearability, scoring resistance；Simultaneously because transparent area glue-line glue is hard, if the thickest pliability that can affect leather, So thickness should control in the range of 0.01-0.05mm.2. primer layer plays the effect of transparent area glue-line and base material bonding, but If the thickest leather softness that can affect, the thinnest bonding that can affect with base material, thus affect wear-resisting, scratch resistance, thickness should Control at 0.10-0.20mm.3. mottle layer mainly makes leather have double-colored effect.

It is merely to illustrate enforcement of the present utility model above in conjunction with this utility model preferred embodiment described by accompanying drawing Mode rather than as to aforementioned utility model purpose and claims content and the restriction of scope, every according to this The technical spirit of utility model, to any simple modification made for any of the above embodiments, equivalent variations and modification, the most still belongs to this reality With new technique and rights protection category.
