(of leather waterproof oil proof agent introduction) - this sentence is not written on the page
Efficient waterproof and oil resistant finishing agent.
When the surface tension of a solid is lower than the surface tension of a liquid, liquid resistance is produced. Leather waterproof agent belongs to the low surface tension of a material, the processing of the fabric can be waterproof, coffee, milk and other water-soluble liquid, in addition, also has excellent durability and resistance to hydrolysis ability, compared with other systems, wax silica gel waterproof agent, processing agent is a higher level.
First, the main use:
When making synthetic leather, add to the polyurethane resin to make the film even and get a smooth effect.
The synthetic leather has waterproof and oil proof properties, and has high waterproof, water resistant, antifouling and decontamination effects.
Two, performance characteristics:
1. all synthetic leather polyurethane solution general purpose.
2. has a good permeability.
3. has a good water repellent effect, so added to the polyurethane surface treatment agent has a good water resistance effect.
4., soft and anti fouling, easy to decontamination effect.
5., the incremental use of this product, against the oily effect better.
6. and polyurethane resin combination, the use of simple, no effect on the stability of the mixture.
Four, usage and dosage (case):
1. Objective: to prevent bubbles and hydrolysis in wet process of leather synthesis
The amount of polyurethane water repellent is 0.4 - 0.8%.
2.. Objective: to improve the water pressure of polyurethane moisture permeable waterproof leather
The amount of polyurethane water repellent is 0.4 - 0.8%.
3. purpose: through the wet treatment of football, football shoes, waterproof and antifouling
The amount of polyurethane water repellent is 0.4 - 0.8%.
Five, processing conditions (case):
Material: non-woven fabric
1, pretreatment: water repellent / DMF = 1 / 4 solution
2, dip pressure: non-woven immersed resin 4 minutes, press roller rolling
3, coagulation: 15% DMF water solution, 38 * 10 minutes
4, wash: 50 degrees, warm water for 20 minutes
5, wash: 10 minutes
6, drying: 110 * 10 minutes
