Definitions
- the present invention relates to synthetic leather.
- Polyurethane resin is widely used for the production of synthetic leather (including artificial leather) because of its mechanical strength and good texture.
- a solvent-based urethane resin containing N, N-dimethylformamide (DMF) has been mainly used so far.
- DMF N, N-dimethylformamide
- Patent Document 1 a urethane resin composition in which a urethane resin is dispersed in water has been widely studied (for example, see Patent Document 1).
- Patent Document 1 As the skin layer of synthetic leather, although the substitution from the solvent system to the water system is gradually increasing in the market, the water system of the urethane resin for the adhesive layer is still advanced. Not. This is mainly because the peel strength of the urethane resin dispersed in water is insufficient compared to the solvent-based urethane resin.
- the problem to be solved by the present invention is to provide a synthetic leather excellent in peel strength and chemical resistance.
- the present invention is a synthetic leather having at least a substrate (i), an adhesive layer (ii), and a skin layer (iii), wherein the adhesive layer (ii) and the skin layer (iii) are both
- the present invention provides a synthetic leather characterized by being formed of a urethane resin using aromatic polyisocyanate as a raw material and a urethane resin composition containing water.
- the synthetic leather of the present invention is excellent in peel strength and chemical resistance.
- a synthetic leather that is further excellent in light resistance and hydrolysis resistance can be obtained. it can.
- the synthetic leather of the present invention can be used for various applications, and in particular, has high durability such as automobile interior materials, furniture, sports shoes, etc. that have been difficult to replace from solvent to water. It can be used for required applications.
- the synthetic leather of the present invention has at least a base material (i), an adhesive layer (ii), and a skin layer (iii).
- both the adhesive layer (ii) and the skin layer (iii) are formed of a urethane resin using aromatic polyisocyanate as a raw material and a urethane resin composition containing water.
- urethane resin composition that can be used for the adhesive layer (ii), for example, a urethane resin (A) that uses aromatic polyisocyanate (a1) as a raw material and water (B) is used. Is preferred.
- the urethane resin (A) can be dispersed in water (B), for example, a urethane resin having a hydrophilic group such as an anionic group, a cationic group, or a nonionic group; B) Urethane resin or the like dispersed in it can be used.
- B a urethane resin having a hydrophilic group such as an anionic group, a cationic group, or a nonionic group
- B Urethane resin or the like dispersed in it can be used.
- These urethane resins (A) may be used alone or in combination of two or more.
- Examples of the method for obtaining the urethane resin having an anionic group include a method using, as a raw material, one or more compounds selected from the group consisting of a compound having a carboxyl group and a compound having a sulfonyl group.
- Examples of the compound having a carboxyl group include 2,2-dimethylolpropionic acid, 2,2-dimethylolbutanoic acid, 2,2-dimethylolbutyric acid, 2,2-dimethylolpropionic acid, 2,2- Herbic acid or the like can be used. These compounds may be used alone or in combination of two or more.
- Examples of the compound having a sulfonyl group include 3,4-diaminobutanesulfonic acid, 3,6-diamino-2-toluenesulfonic acid, 2,6-diaminobenzenesulfonic acid, N- (2-aminoethyl)- 2-Aminosulfonic acid, N- (2-aminoethyl) -2-aminoethylsulfonic acid and the like can be used. These compounds may be used alone or in combination of two or more.
