Problems solved by technology

However, the fenders commonly used in the market currently have the following two disadvantages: one is that they do not have luminous and reflective functions. It is easy to collide with other ships or wharves, and there is a big safety hazard. It does not have reflective function, so it is not easy to be found by other ships during the day and night, which increases the probability of ship collision accidents, and is not very safe. ; Second, in the production process of fenders, parameters such as material mixing temperature and pouring temperature have a great impact on its mechanical properties. However, in the production process of common fenders, the control of parameters such as temperature is not very accurate, which seriously The mechanical properties such as tensile strength and elongation at break of the finished fender are affected. The third is that the common fenders are usually black, so they are not very beautiful, especially in the dark night, the visibility of the whole black fender is basically zero, and it cannot form a beautiful landscape

Abstract

The invention discloses a production process of a noctilucent landscape fender. The production process comprises the following steps: a, preparing pouring slurry; b, performing pouring molding; c, spraying a reflective layer; and d, pouring a surface transparent layer. The noctilucent landscape fender has the advantages that the noctilucent landscape fender has a very good visual effect in the daytime and at night, is very beautiful, has very good wear resistance, and still has relatively high transparency after being worn for a long time, and the noctilucent and reflective effects are not influenced.

Description

technical field [0001] The invention relates to the technical field of fender production technology for ships and wharves, more specifically to the technical field of polyurethane fender production technology for ships and wharves. Background technique [0002] The fender is an elastic buffer device used on the edge of the ship, which is mainly used to slow down the impact force between the ship and the wharf or the ship during the berthing or mooring process, and prevent the ship or the wharf from being damaged. However, the fenders commonly used in the market currently have the following two disadvantages: one is that they do not have luminous and reflective functions. It is easy to collide with other ships or wharves, and there is a big safety hazard. It does not have reflective function, so it is not easy to be found by other ships during the day and night, which increases the probability of ship collision accidents, and is not very safe. ; Second, in the production pro...
