Abstract
The present invention relates to a portable ship fender which is made of a rubber and plastic foam body with closed holes, particularly to a safe protection apparatus for ships in docking. The present invention is characterized in that the mixture of synthetic rubber, high-pressure polyethylene, etc. serves as raw material; disposable whole foaming molding technology is adopted. The present invention has the advantages of light weight, good elasticity, large energy suction amount, strong buffering capability, quick restoration, no water absorption, good weathering resistance performance, convenient operation, high safety, reliability, long service life, wide raw material source, low price, etc.
Description
The present invention is a kind of kinetic energy that is used for absorbing boats and ships during for alongside between naval vessel and harbour or ship, alleviates, mutual extrusion and collision between buffer vessel and harbour or ship the safety equipment of protection ship and harbour.
The present hand-held design fender that uses, domestic have brown fender, rattan fender, used tire fender and an air block fender etc.Preceding two kinds of fenders do not have elasticity, and energy absorption is little, and buffer capacity is poor, and hygroscopic character is strong, and service life is short, and is dangerous; The used tire fender is too heavy, uses inconvenience; Though the air block fender good springiness, energy absorption is big, costs an arm and a leg, and inflates loaded down with trivial detailsly, bumps quick-fried danger in addition.Once use overvoltage miniature rubber fender, Puffer-type ethene fender abroad, occurred high pressure polyethylene foamed plastic fender in recent years again, but all there was different shortcomings in these fenders.Compression-type rubber fender weight is big, and price is expensive, uses inconvenience; Puffer-type ethene fender also exist inflation loaded down with trivial details with bump quick-fried fraud.In light weight, good springiness, the polyethylene foams that energy absorption is big because the foaming difficulty is very big, can only send the sheet polyethylene foams of limited thickness, for practicality, have to it is glued together from level to level.The fender bulk strength of making like this is poor, fracture easily, and the construction technology complexity can not one-shot forming be made hand-held design foam fender peculiar to vessel.The foam fender a kind of peculiar to vessel that the RUBBER MILLERS company of the U.S. produces recently, crust is rubber and polyurethane foam, inner is that core is formed with polyethylene foam.This fender good springiness, energy absorption is big, and has wear-resisting, oil resistant, anti-day advantage such as light aging, but on method for making more complicated, use the expansion of rubber/plastics compound to form foaming body more.The GB 2041948A of British patent introduced use butadiene-acrylonitrile rubber, Koroseal, polymethyl methacrylate compound in addition foaming agent become foamable component, to form foaming body.Its component has various improvement, comprises polyvinylchloride, butadiene-acrylonitrile rubber etc.And but the present invention adopts compounds such as poly-chloroprene rubber, high pressure polyethylene, ethylene-vinyl acetate copolymer foaming agent formation foaming component in addition, to form foaming body.
The invention provides the hand-held design foam fender peculiar to vessel that a kind of rubber and plastic closed-cell foam that forms with the one-shot forming integral foam is made.This fender good springiness, energy absorption is big, and is in light weight, and globality is strong, low price, implementing process is simple, the safety precaution problem when having solved ship berthing.
Realization of the present invention is to be base-material with rubber (or regeneratd rubber) and plastics (or regenerated plastics), adds foaming agent, blowing promotor etc. and mixes back disposable integrals foaming and form closed-cell foam.
Rubber and plastic hybrid are the important raw and processed materials of making closed cell foam.This product uses neoprene (or regeneratd rubber) and high pressure polyethylene (or regeneration high pressure polyethylene) to be base stock, selecting H, AC or OBSH for use is foaming agent, lead sulfate tribasics etc. are blowing promotor, cumyl peroxide is a crosslinking agent, adds high impact polystyrene and ethylene-vinyl acetate copolymer auxiliary materials such as (EVA).Its weight proportion is as follows:
Base stock:
15～45 parts of neoprene (or regeneratd rubber);
20～80 parts of high pressure polyethylenees (or regenerated polythene);
Foaming agent:
2～20 parts of H, AC or OBSH;
Blowing promotor:
0.10～0.25 part of hard ester acid;
0.10～0.25 part of lead sulfate tribasic;
1.5～5.0 parts of dibutyl phthalates;
Crosslinking agent:
0.2～1.0 part of cumyl peroxide;
Auxiliary material:
3～20 parts of high impact polystyrenes (HIPS);
10～70 parts of ethylene-vinyl acetate copolymers (EVA).
Said components is good by prescription requirement weighing, with the roller temperature rise of opening rubber mixing machine to proper temperature, reinforced plasticating, add then rubber carry out mixing, treat mixing evenly after, add foaming agent, crosslinking agent, it is stand-by by sheet under the desired thickness fully to mix the back.Forming mould needs behind the brushing mold release charging and adds the plug matched moulds to send into curing system (or foaming), and used steam pressure is 4～7 kilograms per centimeter
2, be that the disposable integral foaming forms the rubber and plastic closed-cell foam through 0.5～3 hour.Foam surface brushing one deck oil resistant, wear-resisting, fire-retardant, aging-resistant rubber-type coating.The density of this product is 0.05～0.5 gram per centimeter
3
The hand-held design fender peculiar to vessel that the rubber and plastic closed-cell foam that is formed by this disposable integral foaming constitutes is compared with the hand-held design fender peculiar to vessel that uses both at home and abroad at present, have in light weight, good springiness, advantage, the safety precaution problem in the time of solving ship berthing effectively such as energy absorption is big, buffer capacity is strong, reinstatement is fast, anti-weather performance is good, globality is strong, forming technology is advanced, esy to use, safe and reliable, long service life, raw material sources are wide, cheap.
Fig. 1 is the structural representation with semi-sictional view of foam fender peculiar to vessel of the present invention.
Referring to Fig. 1, hand-held design of the present invention fender peculiar to vessel has the rubber and plastic closed-cell foam 1 that adopts the disposable integral foaming to form, and it is shaped as cylinder, two termination hemispheres, and the center has eyelet hole vertically, and there is anti-skidding rib on the surface; Be consolidated with polysulphide rubbers plug 2 at the two ends of rubber and plastic closed-cell foam 1, the aperture of eyelet hole is identical on its shape approximation disc, centre hole and rubber and plastic closed-cell foam; External coating at rubber and plastic closed-cell foam 1 has rubber-type aging-resistant flame-proof coatings decoration layer 3.
The concrete production process of hand-held design of the present invention fender peculiar to vessel is:
Earlier high pressure polyethylene (or regenerated polythene) 20～80 grams, high impact polystyrene 3～20 grams, ethylene-vinyl acetate copolymer 10～70 grams are put into opening rubber mixing machine plasticate (the roller temperature is 100～130 ℃), thereafter adding rubber (or regeneratd rubber) 15～45 gram, hard ester acid 0.10～0.25 gram, lead sulfate tribasic 0.10～0.25 gram, dibutyl phthalate 1.5～5.0 grams carries out mixing, treat that evenly the back adds foaming agent, at this moment the roller temperature should be reduced to 70～100 ℃.Under same temperature, add cumyl peroxide, fully mixing after on demand under the thickness sheet stand-by.Forming mould needs after the agent of brushing rubber moulding charging and adds the plug matched moulds, send the slaking of foaming in the vulcanizing tank.Used steam pressure is 4～7 kilograms per centimeter
2, through being finished product in 0.5～3 hour.Finished surface brushing one deck oil resistant, wear-resisting, fire-retardant and aging-resistant rubber-type coating, and the anti-skidding rib of roll extrusion.
