Problems solved by technology

[0002] Deck covering is a covering material laid on the deck of a ship. It has properties such as heat insulation, noise reduction, anti-rust, and anti-skid. At present, the commonly used latex-type deck covering mainly uses latex and cement as the main raw materials. This kind of dressing has good fire resistance. , impermeability, impact resistance, can effectively isolate noise and heat conduction, and it has good cohesiveness and water resistance, and will not produce cracks, but the composition of the existing latex-type deck coverings is relatively complicated, which improves the quality of the product. The cost reduces the economic benefit of the production enterprise, and the proportion of the deck is relatively large, causing a large part of unnecessary load to the ship, increasing the self-weight of the ship, affecting the speed and load capacity of the ship, and Traditional deck coverings contain asbestos, which seriously affects the environment. Therefore, there is an urgent need for an environmentally friendly latex deck covering that is simple to produce and process, economical and affordable, and has a lighter specific gravity.
