Description
Technical Field
The invention particularly relates to a floating body of a PDCPD composite material and a manufacturing method thereof.
Background
The PDCPD material is thermosetting plastic with a cross-linked three-dimensional network structure, has the advantages of low density, good low-temperature performance, good insulating property, good wave permeability, strong impact resistance, corrosion resistance and the like, and is widely applied to the fields of vehicle parts, large-scale shells, corrosion-resistant parts, military equipment and the like.
The floating body is usually made of plastic, metal, concrete, etc. and is a closed hollow floating object. The disadvantages are that: 1) poor strength, poor impact resistance and easy deformation; 2) when the device is damaged and leaks water, the device fails to work and cannot work; 3) the corrosion resistance in a liquid medium is poor throughout the year, and corrosion resistance treatment is needed; 4) the cost of the related production equipment is high when the large-scale floating body which is formed in one step is manufactured.
Therefore, it is urgently needed to develop and design a floating body with simple structure, low cost, high strength and good stability.
Disclosure of Invention
The invention aims to provide a floating body of a PDCPD composite material and a manufacturing method thereof aiming at the defects of the prior art, and the floating body of the PDCPD composite material and the manufacturing method thereof can well solve the problems.
In order to meet the requirements, the technical scheme adopted by the invention is as follows: provides a floating body of PDCPD composite material and a manufacturing method thereof, the floating body of PDCPD composite material and the manufacturing method thereof comprise
The floating body of the PDCPD composite material and the manufacturing method thereof have the advantages that:
(1) the composite material has better impact resistance. The PDCPD material has good mechanical property and good toughness, and low-density polyurethane foam filled inside has certain elasticity. The two materials are combined, so that the floating body has better impact resistance.
(2) Good stability and no fear of breakage and water leakage. Since the filled low-density polyurethane foam has a density of 1/30, which is the density of water, and a closed cell ratio of more than 95%, the material has excellent floating properties and can provide sufficient buoyancy even if it is broken or perforated. Because the PDCPD material is an elastic material with certain strength, the PDCPD monomer can not crack even if the PDCPD monomer cracks, and the PDCPD monomer has better shape retention when the PDCPD monomer is cracked by matching with other high-strength and high-toughness materials (such as aramid fiber, high molecular weight polyethylene fiber and the like) and a polyurethane hard foam filling composite structure.
(3) The PDCPD material has excellent corrosion resistance. No additional corrosion-resistant treatment is needed, and the method is particularly suitable for seawater and sewage environments. The advantages of small coating adhesion and good PDCPD coating adhesion are utilized, and various appearance decorations can be sprayed and brushed.
(4) The PDCPD material belongs to a thermosetting high polymer material, and has better low-temperature mechanical property compared with the traditional hot-melt material. The product has good strength in the low-temperature hydrological environment of ice-water mixing and is not easy to become brittle.
(5) Both PDCPD materials and polyurethane materials are suitable for reaction injection molding processes. By means of the technological advantages of RIM, the method is particularly suitable for manufacturing floating bodies (such as paradise boats, fishing boats, pontoon boxes of pontoon bridges, large buoys, engineering ship bodies and the like) with large weight and large size of single bodies with lower equipment and energy consumption investment.
(6) The product has simple manufacturing process, high production speed, low production energy consumption and little pollution. The PDCPD shell is formed by adopting a reaction injection molding method, the process is simple, and the production efficiency is high. PDCPD releases heat during polymerization, and does not need to open a mold for heating in the whole injection molding process, so that the energy consumption of equipment for manufacturing the same product is lower, and the pollution is less.
