The invention discloses a production method of waterproof
organosilicon modified
solvent-free
polyurethane synthetic leather. The production method comprises the following steps: firstly, adding a component A containing hydroxyl and a component B containing an
isocyanate group into a reaction still, and reacting by stirring to obtain foaming
slurry; secondly, adopting a dry process
production line of the synthetic leather, blade
coating the foaming
slurry on release paper to form a
coating, and then laminating the
coating with a base fabric by a gap fitting mode through a laminating
machine; thirdly, feeding a mixture into a
drying oven for cooking to obtain the waterproof
organosilicon modified
solvent-free
polyurethane synthetic leather. According to the production method disclosed by the invention, the waterproof
organosilicon modified
solvent-free
polyurethane synthetic leather is produced by adopting a double foaming technology, a polyurethane in-situ
polymerization waterproof technology, a heat-sensitive catalyst asynchronous
catalysis technology and a single-pole constant temperature heating scrape coating technology; the production technology is
environmentally friendly, simple, and stable; the quality of a product is good; a
contact angle of water droplets on the surface of the synthetic leather is as high as 107 degrees, and static
water seepage prevention can be kept for 15 days; the waterproof organosilicon modified solvent-free polyurethane synthetic leather can be used as a high-end functional yacht seat covering material.
