[0002] In the prior art, in the production process of dry-process PU synthetic leather and wet-process PU synthetic leather, sticking phenomenon will inevitably occur, and the surface of the produced synthetic leather is highly viscous, not smooth enough, and has poor hand feeling, which is not up to the current standards. Requirements for synthetic leather
There are many kinds of anti-sticking agents on the market, but there is no anti-sticking agent specially used in the production of synthetic leather
Usually, in order to reduce the viscosity of the surface of synthetic leather, the way to take is to add a surfactant with better lubricity into the synthetic leather slurry, such as polyether modified silicone oil, and use polyether modified silicone oil as a component of the slurry composition. A component that can enhance the lubricity between the components, but it cannot improve the surface viscosity and smoothness of the synthetic leather, so the synthetic leather feels poor

Embodiment 1
[0022] According to the PU leather anti-stick slippery agent of the present embodiment, its formula is as follows:
[0024] The preparation method of anti-sticking slippery agent for PU leather is:
[0025] Weigh 15 grams of cellulose ester, 25 grams of polyacrylamide, 5 grams of polyether modified silicone oil, and 5 grams of Tween-80, mix, stir at room temperature for about 30 minutes, and then add 50 grams of DMF to adjust the viscosity to 1500cps is the finished product.
Embodiment 2
[0027] According to the PU leather anti-stick slippery agent of the present embodiment, its formula is as follows:
[0029] The preparation method of the anti-stick slip agent for PU leather is the same as above.
[0030] The consumption of the present invention is:
[0031] When the PU resin with a solid content of 30% is 100 parts, the addition amount is 0.1-0.3 parts.
[0032] Practice has proved that the anti-stick slip agent product for PU leather of the present invention has excellent anti-stick and smooth effects on PU leather, especially good anti-stick effect on low-modulus polyurethane resin, and this product is added to PU After the leather slurry, it has good compatibility, does not migrate, and has no adverse effects on the physical properties of PU leather and release paper; in addition, this product also has the advantages of wear ...

Abstract
The invention relates to an antiseizing slip agent for PU leather. The compositions in weight portion are: 10 to 20 portions of cellulose ester, 20 to 30 portions of polyacrylamide, 40 to 60 portions of DMF, 3 to 7 portions of polyether modifying silicon oil and 3 to 7 portions of tween-80. When the PU leather is produced, the antiseizing slip agent for the PU leather is added into a PU leather sizing agent, thereby effectively reducing the viscosity of the PU leather surface, therefore, the PU leather surface is smooth and has high planeness.
Description
technical field [0001] The invention belongs to the field of synthetic leather synthesis, in particular to an anti-sticking slip agent used in the production of dry and wet PU synthetic leather. Background technique [0002] In the prior art, in the production process of dry-process PU synthetic leather and wet-process PU synthetic leather, sticking phenomenon will inevitably occur, and the surface of the produced synthetic leather is highly viscous, not smooth enough, and has poor hand feeling, which is not up to the current standards. Requirements for synthetic leather. There are multiple anti-adhesive agents on the market, but there is no anti-adhesive agent specially used in the production of synthetic leather. Usually, in order to reduce the viscosity of the surface of synthetic leather, the way to take is to add a surfactant with better lubricity into the synthetic leather slurry, such as polyether modified silicone oil, and use polyether modified silicone oil as a co...
