The above conditions will affect the staff and the environment. For example, if the reaction time of the substrate and the foaming agent is too short, there will be It is difficult to evenly mix and enter the foaming state. In addition, some conventional foaming materials have a foaming temperature of about 120 degrees Celsius. Only materials that can withstand the foaming temperature can be used for the coating layer, which limits the types of materials that can be used for the coating layer.

FIG. 3 is a flow chart of the foam filling method of the buoyancy body of the present invention.

As shown in FIGS. 1-2, the boat 100 of the present invention with an improved buoyant body filled with foam material includes: a buoyant body 1, generally tubular and generally U-shaped, composed of a first cladding layer 11 and filled in A foam material 12 inside the first cladding layer 11 is formed; and a bottom plate 2 is provided at the bottom of the buoyancy body 1; and a tail plate 3 is provided at the rear end of the buoyancy body 1 and the bottom plate 2; its characteristics are: buoyancy The foaming material 12 of the body 1 is formed by mixing and foaming polyether polyol and diisocyanatodiphenylmethane; with this structure, the purpose of improving the safety when filling the foaming material can be achieved. This will be explained in detail below.

As shown in FIG. 3, the present invention further discloses a method for foaming and filling a buoyant body, which includes the following steps: S11 control step to control the temperature of the polyether polyol to a predetermined temperature range; S12 mixing step to change the polyether polyol Mix with diisocyanatodiphenylmethane to form a mixed liquid; S13 pouring step, the mixed liquid is poured into the first coating layer of a buoyant body to foam-fill the buoyant body.

The buoyancy body 1, the bottom plate 2 and the tail plate 3 can form a solid buoyancy body, which can be used to carry people or objects, for example.

The foam material 12 of the buoyancy body 1 is formed by mixing and foaming polyether polyol and diisocyanatodiphenylmethane. Foam material 12 polyether polyol and two Isocyanic diphenylmethane can use PU-G8912 polyether polyol sold by Libo Technology Co., Ltd. and MILLIONATE MR-100 diisocyanic diphenylmethane, both of which are liquid at normal temperature.

The polyether polyol and diisocyanatodiphenylmethane are mixed into a liquid state (hereinafter referred to as a mixed liquid). The mixed liquid will enter a foaming state after a predetermined reaction time. In the foaming and filling process, for example, the predetermined reaction time of the mixed liquid and the temperature in the foamed state are all related to the safety of the staff. In the present invention, by adding 80 to 120 parts by weight of diisocyanatodiphenylmethane per 100 parts by weight of polyether polyol, supplemented by the aforementioned foaming and filling method, the predetermined reaction time and foaming of the mixed liquid can be achieved Numerical values such as temperature in the state are controlled to the state most suitable for filling in the first cladding layer of the buoyant body.

The S11 control step is to control the temperature of the polyether polyol to a predetermined temperature range. The predetermined temperature range is any temperature above the freezing point and below the boiling point of the polyether polyol, so as to facilitate the uniform mixing of the polyether polyol and the diisocyanic diphenylmethane.

S12 mixing step is to mix polyether polyol and diisocyanatodiphenylmethane to form a mixed solution.

As mentioned above, the predetermined reaction time of the mixed liquid is related to the safety of the staff, because the length of the predetermined reaction time will affect the working time of the staff. If the predetermined reaction time is too short, it will cause pressure on the staff and it is easy to make mistakes. According to the material characteristics of the polyether polyol of the present invention, when the temperature of the polyether polyol is closer to the freezing point, the longer the predetermined reaction time after the polyether polyol and diphenylmethane diisocyanate are mixed into the foamed state, Therefore, the effect of controlling the predetermined reaction time can be achieved by controlling the temperature of the polyether polyol, which can facilitate the staff to uniformly reconcile the polyether polyol and diiso Diphenylmethane cyanate, for example, reduces the lack of uneven foaming due to uneven mixing. In addition, since the predetermined reaction time of the mixed liquid can be controlled, the worker does not need to rush to inject the mixed liquid into the first coating layer, which can increase the safety of the entire foaming and filling process.

In the step S13 of pouring, the mixed liquid is poured into the first coating layer of a buoyant body to fill the buoyant body with foam. When pouring the mixed liquid into the first coating layer of the buoyant body, the mixed liquid can be poured into the first coating layer of the buoyant body by high-pressure infusion so that the buoyant body can be filled after the mixed liquid enters the foaming state Inside the first cladding layer.

An anti-collision cylinder 4 of substantially round rod shape can be placed around the outer side of the buoyancy body 1 not only to form a crash protection structure for the buoyancy body, but also to increase the stability of the buoyancy body and to be used as a person in the water to climb up Stepping on stairs when buoyant body.

The crash tube 4 can be composed of a second cladding layer 41 and a foam material 42 filled in the second cladding layer 41. The foaming material 42 of the crash cylinder 4 can be the same as the foaming material 12 of the buoyancy body 1 can be made of a mixture of polyether polyol and diisocyanatodiphenylmethane, and the foaming material of the crash cylinder can include 100 parts by weight Of polyether polyol and 80-120 parts by weight of diisocyanatodiphenylmethane, in order to improve the safety of the crash tube 4 when filled with foam material.

The above is the embodiment cited in this case, which is only for the convenience of explanation, but the meaning of this case cannot be limited in this way, that is, all kinds of altered designs according to the scope of the patent application listed should be included in the patent scope of this case.
