At present, due to the release paper restriction to leather lines, current organosilicon synthetic leather surface pattern is the deepest or peculiar lines release paper is difficult to buy, it is impossible to meet some fields to deep lines or the demand of peculiar lines organosilicon synthetic leather.Some deep lines synthetic leather is relatively deep due to lines, and at deep lines, the bubble in raw material is difficult to drain, and after molding, leather surface has bubble, causes the performance impairment such as the outward appearance of leather, wear-resisting, scratch resistant.
Utility model content
This utility model is for the deficiency of the problems referred to above, a kind of deep lines organosilicon synthetic leather is proposed, use and carve lines needed for mixing to liquid silica gel strong for thixotropy or add-on type Silica Surface is extruded by textured pressure roll, be bonded with liquid silica gel with base material again after sulfuration.The preparation method of described deep lines organosilicon synthetic leather has clear superiority in terms of preparing deep lines and novel lines organosilicon synthetic leather.When utilizing release paper to produce deep lines leather, because release paper lines is relatively deep (more than depth of groove 0.15mm), in release paper during applying glue, silica gel is difficult to drain bubble in grain groove, silica gel endogenous cause of ill has bubble wrap reason hydraulic performance decline that the scratch resistant of leather and wearability are declined, and this utility model to be first applying glue back roller swaging become lines can avoid this problem.Being simultaneously to be determined by institute's rag road, pressure roll surface because of leather lines, this utility model can solve the problem that leather lines is limited by release paper.
This utility model is that the technical scheme solving the proposition of above-mentioned technical problem is:
A kind of deep lines organosilicon synthetic leather, including the lines layer (3) set gradually from top to bottom, tack coat (2) and base material (1).
Further: soft layer (4) also can be set between described tack coat (2) and base material (1).
Preferred: described lines layer (3), tack coat (2), soft layer are together with base material (1) composite joint successively.
Preferred: described lines layer (3) is to be formed through carving textured pressure roll roll-in after cure by the add-on type silica gel without mobility.
Preferred: described tack coat (2) is that the sulfuration of add-on type liquid silica gel forms, and plays the effect of lines layer with base material bonding.
Preferred: described base material (1) is made for any one or more in super fine, the glass of chemistry super fine, cotton, numb, paper, metal.
The preparation method of a kind of deep lines organosilicon synthetic leather, comprises the following steps:
Step a, uses curtain coating mode to be coated on release paper or mould release membrance in the add-on type silica gel without mobility, by carving textured pressure roll, Silica Surface is made to extrude lines, vulcanize 1～20 minute at a temperature of 80～200 DEG C, peel off release paper or mould release membrance, prepare lines layer (3).
Step b, makees tack coat (2), the lines layer (3) that laminating step a prepares at base material (1) surface-coated liquid silica gel, vulcanizes 1～20 minute, can be prepared by deep lines organosilicon synthetic leather at a temperature of 80～200 DEG C.
Preferred: in order to increase leather softness, make tack coat (2) in stepb front, first can form soft layer (4) after one layer of soft silica gel of base material (1) surface-coated or foamed silica gel vulcanize, then on soft layer, applying liquid silica gel makes tack coat (2).
One of the present utility model deep lines organosilicon synthetic leather, compared to existing technology, has the advantages that
This utility model includes lines layer (3), tack coat (2) and the base material (1) set gradually from top to bottom, use and carve lines needed for mixing to liquid silica gel strong for thixotropy or add-on type Silica Surface is extruded by textured pressure roll, be bonded with liquid silica gel with base material again after sulfuration.The method that the utility model proposes is that the preparation of deep lines and novel lines organosilicon synthetic leather provides effective method, and preparation method is simple, and preparation process will not produce harmful substance, the product environmental protection of preparation, harmless.
In order to improve the pliability of leather, soft or foamed silica gel can be coated on base material, form soft layer (4).The preparation method of described deep lines organosilicon synthetic leather has clear superiority in terms of preparing deep lines and novel lines organosilicon synthetic leather.When utilizing release paper to produce deep lines leather, because release paper lines is relatively deep (more than depth of groove 0.15mm), in release paper during applying glue, silica gel is difficult to drain bubble in grain groove, silica gel endogenous cause of ill has bubble wrap reason hydraulic performance decline that the scoring resistance of leather and wearability are declined, and this utility model to be first applying glue back roller swaging become lines can avoid this problem.Being simultaneously to be determined by institute's rag road, pressure roll surface because of leather lines, this utility model can solve the problem that leather lines is limited by release paper.
