Description
Technical Field
The invention relates to a boat with a strengthened buoyancy body and a foaming filling method of the buoyancy body; more particularly, to a boat having a buoyant body composed of a first coating layer and a foaming material filled in the first coating layer, and improving the foaming material in the buoyant body, and a foaming filling method of the buoyant body.
Background
Patent document 1: taiwan patent publication No. M381588.
In patent document 1, the inventor proposed a "overturn-preventing land-based lifeboat" which is characterized in that a buoyant body is composed of a cladding and a foam material filled in the cladding, and has an advantage that water or foam material leakage in the cladding hardly occurs even if the cladding is accidentally damaged, thereby affecting buoyancy, and a boat in which the cladding of the buoyant body is filled with a foam material has been known as a foam-filled boat through many years of development.
Common foam filled boats are based on rubber boats and are further developed to save many structural design costs. In addition, since the inside of the coating layer of the buoyant body is filled with the foaming material, the strength of the buoyant body is increased, and thus the buoyant body is further widely applied to fields such as lifeboats, transport boats, fishing boats, and the like.
In reference 1, it is only disclosed that the foaming material can be polyester amine foam or other similar foaming artificial resin material such as EVA, but there are many differences between different foaming artificial resin materials, such as different base material and required foaming agent, different reaction time after mixing base material and foaming agent, different melting temperature, different temperature during foaming, etc., all of which affect working personnel and environment, for example, if the reaction time after mixing base material and foaming agent is too short, it is difficult to mix them uniformly and enter into a foaming state. In addition, some common foaming materials have a foaming temperature of about 120 ℃, and the coating layer can only adopt a material capable of bearing the foaming temperature, so that the type of the material which can be adopted by the coating layer is limited, for example, the coating layer cannot be made of materials such as polyvinyl chloride (PVC).
In view of the above, the inventors of the present invention have conducted active research on the above-mentioned materials, and have conducted many years of experience in research on related products, and have conducted continuous tests and improvements to develop the present invention.

Detailed Description
In order to clearly understand the technical solution, the purpose and the effect of the present invention, a detailed description of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1 to 2, a boat 100 with a reinforced buoyant body according to the present invention includes: a buoyancy body 1, which is substantially tubular and substantially U-shaped, and is composed of a first coating layer 11 and a foaming material 12 filled in the first coating layer 11; a bottom plate 2 arranged at the bottom of the buoyancy body 1; the tail plate 3 is arranged at the rear end of the buoyancy body 1 and the rear end of the bottom plate 2; the foaming material 12 of the buoyancy body 1 is formed by mixing and foaming a first material and a second material; the first material is composed of Polyether polyol; the second material is formed by mixing Polymethylene polyphenyl isocyanate (Polymethylene polyphenyl isocyanate) and 4, 4-isocyanic acid diphenylmethane (Methylene bisphenyiisocyanate); by the structure, the purpose of improving the safety when the foaming material is filled can be achieved. As will be described in detail below.
As shown in fig. 3, the present invention further discloses a method for filling a floating body with foam, which comprises the following steps: s11: a control step of controlling the temperature of the first material within a predetermined temperature range; s12: mixing, namely mixing the first material and the second material into a mixed solution; s13: and a pouring step, pouring the mixed liquid into a first coating layer of a buoyancy body to fill the buoyancy body with foam.
The buoyancy body 1, the bottom plate 2 and the tail plate 3 can constitute a firm buoyancy body which can be used for carrying people or articles, for example.
The foaming material 12 of the buoyant body 1 is formed by mixing and foaming a first material and a second material. The first and second materials of the foam material 12 may be PU-G8912 polyether polyol sold by li PO techonogy co, LTD and millinate MR-100 diphenylmethane diisocyanate, respectively, both of which are liquid at room temperature. The first material is composed of polyether polyol. The second material is formed by mixing polymethylene polyphenyl isocyanate and 4, 4-isocyanic acid diphenylmethane, in particular to the mixture of polymethylene polyphenyl isocyanate with the concentration or the concentration range of less than 99 percent and 4, 4-isocyanic acid diphenylmethane with the concentration or the concentration range of 44 percent.
The first material and the second material are mixed to be in a liquid state (hereinafter referred to as a mixed liquid). The mixed solution enters a foaming state after a predetermined reaction time. In the foaming and filling step, the safety of workers is affected by the numerical values such as the predetermined reaction time of the mixed liquid and the temperature in the foaming state. The present invention can control the values of the predetermined reaction time of the mixed liquid, the temperature in the foaming state, and the like to be in the optimum state for filling the first coating layer of the buoyant body by adding 80 to 120 parts by weight of the second material to 100 parts by weight of the first material and by using the foaming filling method described above.
S11: the control step is to control the temperature of the first material within a predetermined temperature range. The predetermined temperature range is any temperature above the freezing point and below the boiling point of the first material, namely the predetermined temperature is greater than or equal to the freezing point of the first material and is less than or equal to the boiling point of the first material, so that the first material and the second material can be conveniently and uniformly mixed in the subsequent process.
S12: the mixing step is to mix the first material and the second material into a mixed solution.
As mentioned above, the predetermined reaction time of the mixed solution is related to the safety of the worker, because the predetermined reaction time affects the working time of the worker, if the predetermined reaction time is too short, the pressure of the worker is generated, and the error is easily generated. According to the invention, through the material characteristics of the polyether polyol forming the first material, when the temperature of the polyether polyol is closer to the solidifying point, the preset reaction time from the mixing of the first material and the second material to the foaming state is longer, so that the effect of controlling the preset reaction time can be achieved by controlling the temperature of the first material, the first material and the second material can be conveniently and uniformly blended by workers, and the defect of incomplete foaming caused by nonuniform mixing can be reduced. In addition, because the preset reaction time of the mixed liquid can be controlled, workers do not need to urgently inject the mixed liquid into the first coating layer, and the safety of the whole foaming filling process can be improved.
S13: the filling step is to fill the mixture into the first coating layer of the buoyant body to foam and fill the buoyant body. When the mixed liquid is poured into the first coating layer of the buoyant body, the mixed liquid can be poured into the first coating layer of the buoyant body in a high-pressure pouring mode so that the interior of the first coating layer of the buoyant body can be filled after the mixed liquid enters a foaming state.
The outer side of the buoyancy body 1 can be surrounded with a round rod-shaped anti-collision tube 4, which not only can form an anti-collision protection structure of the buoyancy body, but also can increase the stability of the buoyancy body, and can be used as a trample step when a person in water climbs the buoyancy body.
The crash tube 4 may be composed of a second coating layer 41 and a foaming material 42 filled in the second coating layer 41. The foam material 42 of the crash tube 4 may be formed by mixing a first material and a second material, as the foam material 12 of the buoyant body 1, and the foam material of the crash tube may include 100 parts by weight of the first material and 80 to 120 parts by weight of the second material, so as to improve the safety when the foam material is filled in the crash tube 4.
The above-mentioned embodiments are provided for illustrative purposes only, and should not be construed as limiting the present invention, i.e., any equivalent changes and modifications that can be made by those skilled in the art without departing from the spirit and principles of the present invention shall fall within the protection scope of the present invention.
