Description

Technical Field

[0001] The present invention relates to the technical field of polyurethane foam materials, and more specifically, to a lightweight sound-insulating and impact-resistant polyurethane foam product for filling a new energy speedboat and a preparation method thereof. Background Art

[0002] Traditional diesel engine speedboats rely on diesel engines to generate power by burning diesel, which drives the propeller to move the speedboat forward. This power system is mature and powerful, but burning diesel will emit a large amount of exhaust gas (including pollutants such as carbon dioxide, nitrogen oxides and particulate matter), which has a negative impact on the atmospheric environment and is also easy to pollute the waters. In addition, the diesel engine produces a lot of noise and vibration when working, which will harm the survival of aquatic organisms.

[0003] New energy speedboats generally use clean energy such as electricity, solar energy, and hydrogen energy as their power source. They basically do not produce or produce very little exhaust gas emissions during use, which has little pollution to the air and water bodies and helps protect the ecological environment of the water bodies. In order to meet the use requirements of the entire new energy speedboat, the internal cavity of the speedboat mostly uses lightweight filling materials to reduce the weight of the hull and reduce the vibration and noise of driving. However, while pursuing lightweight, it also reduces safety. However, the current filling materials have general impact resistance. During high-speed driving, the vibration and impact generated by the contact between the water surface and the hull and the movement of the engine can easily cause the filling materials to deform or even crack after long-term driving, affecting the sound insulation performance of the new energy speedboat during driving. Therefore, it is urgent to develop a polymer material that meets the requirements of light weight, impact resistance, and sound insulation, which can serve as a multifunctional filling material for new energy speedboats. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a lightweight sound-insulating and impact-resistant polyurethane foam product for filling new energy speedboats and a preparation method thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A lightweight sound-insulating and impact-resistant polyurethane foam product for filling new energy speedboats is prepared from component A and component B in a mass ratio of 100:100-105; component A consists of the following ingredients in parts by weight: 30 parts of high-resilience ether polyol, 20 parts of sucrose polyether polyol, 20 parts of CASE polyether polyol, 25 parts of flame retardant, 1-2 parts of foam stabilizer, 2-3 parts of emulsifier, 2-3 parts of catalyst, and 5-8 parts of deionized water; component B is Desmodur 44V20L polymethylene polyisocyanate.

[0007] The present invention is further configured that the high resilience ether polyol is a high resilience polyether polyol EP-330NG.

[0008] The present invention is further configured that the sucrose polyether polyol is a high-activity sucrose polyether polyol PURANOLRFW835E V1.022-01-24.

[0009] The present invention is further configured such that the CASE polyether polyol is Puranol G310.

[0010] The present invention is further configured such that the flame retardant is a halogen-free flame retardant TEP.

[0011] The present invention is further configured such that the foam stabilizer is the surfactant EP-RS 81.

[0012] The present invention is further configured such that the emulsifier is emulsifier NP-10.

[0013] The present invention is further configured such that the catalyst is a reactive catalyst PC-37.

[0014] A method for preparing a lightweight sound-insulating and impact-resistant polyurethane foam product for filling a new energy speedboat comprises the following steps: uniformly stirring the components of component A according to a certain proportion, and then uniformly mixing component A and component B and then foaming the mixture.

[0015] In summary, the present invention has the following beneficial effects:

[0016] With high resilience ether polyol, sucrose polyether polyol, CASE polyether polyol and Desmodur 44V20L polymethylene polyisocyanate as raw materials, flame retardants, foam stabilizers, emulsifiers and catalysts are added to make lightweight, sound-insulating and impact-resistant polyurethane foam products, which can meet the high-performance use requirements of new energy speedboat filling materials; and the addition of highly active sucrose polyether polyol PURANOL RFW835E V1.022-01-24 and surfactant EP-RS 81 can further enhance the impact resistance and sound insulation performance of the foam material, and it has excellent high temperature resistant dimensional stability, which is suitable for higher application requirements.
