A high-strength and high-memory composite
polyurethane board with antifouling function and its preparation method. The raw materials of the board include organic
silicon,
polyurethane resin modified by organic
fluorine, wear-resistant materials, reinforcing materials, colorants, light stabilizers,
Antioxidant,
coupling agent and dispersant are produced through kneading, degassing, molding,
vulcanization, aging, and heat sealing process with
fiber cloth; the invention has excellent stretch resistance,
puncture resistance,
weather resistance and
wear resistance ,
corrosion resistance and low
surface energy, can effectively prevent
biofouling and occasions where antifouling coatings cannot be applied, and is suitable for heavy-attachment areas of marine structures in marine structures; it can be used in conjunction with petrolatum anti-
corrosion products to achieve heavy-duty anti-
corrosion and anti-
fouling Pollution dual function; or add to the outer layer of the existing PTC and other
coating anti-corrosion systems, increase the anti-
fouling function of PTC and other technologies, broaden the application field of PTC and other
coating anti-corrosion technologies, suitable for building materials for manufacturing offshore platforms, and can solve the problem of rivers and rivers Anti-corrosion and anti-
fouling and high-strength technical problems for buildings and ship structures in lakes and seas.
