Product introduction:

Guanidine carbonate is a very widely used organic synthesis raw materials and analytical reagents, mainly used in amino resin pH regulator, antioxidant, resin stabilizer and soap, but also used as cement slurry, surfactant additives. It can also be used as moisture-resistant agent and synergist of detergent, cosmetic raw materials and so on.

 

Guanidine carbonate application field:

There are more than 18,000 species of attached animals and 600 species of attached plants in the Marine areas of the world. When the bottom of the ship is attached to Marine organisms, the resistance increases, the speed decreases, the fuel consumption increases, and the mechanical wear increases. The attachment of sea creatures also destroys the paint film and accelerates the corrosion of the steel plate. So far, the application of Marine antifouling coatings is the most economical and effective measure to prevent the attachment of Marine organisms. The antifouling coating forms a paint film at the bottom of the ship, and gradually releases the toxic material through the exudation, diffusion or hydrolysis of the toxic material in the paint film, so as to prevent the Marine attached organisms from attaching to the bottom of the ship or Marine underwater facilities. The patent CN108587273A provides an anti-fouling coating for the outer layer of ships and its preparation method. The outer antifouling coating consists of 30 ~ 50 weight parts of acrylic, 10 ~ 18 weight parts of pine wax resin, 5 ~ 8 weight parts of polymer composite antifouling masterbatch, 1 ~ 5 weight parts of white carbon black, 10 ~ 20 weight parts of organic modified bentonite, 5 ~ 10 weight parts of pigment filler, 1 ~ 4 weight parts of defoamer and 15 ~ 25 weight parts of composite solvent.The polymer composite antifouling masterbatch is a polymer material composed of polyamine and guanidine salt. The specific steps for preparing the polymer composite antifouling masterbatch are as follows: 100g ethylenediamine and 190g guanidine carbonate (CAS:593-85-1) were added to a 500ml three-neck bottle under the protection of nitrogen, stirred and heated to 100℃ for 1 hour; Then it was heated to 190℃ for 8 hours. Then 15g maleic anhydride was added and the reaction ended 15 minutes later with an average molecular weight of 2800.

The patent antifouling coating adopts polymer composite antifouling masterbatch for sterilization and antifouling, which has high bactericidal activity and expands the broad spectrum of sterilization; And the texture is fine and smooth, which improves the smoothness of the coating surface.
