Abstract
The utility model relates to an elastic surface closing micropore sleeve for the artificial limb of a lower limb. The utility model, which is composed of a socket 1, a rigid skeleton 2, a joint 3, a foot 4, a coating sleeve 5 and an elastic surface closing micropore layer 6, overcomes the defect of an existing opening micropore outer layer sleeve which is molded through grinding machining, and has the functions of water prevention, dust prevention, wear-resistance and beauty. The utility model can prevent metallic skeletons and metallic joints from being corroded, and in addition, the surface is lifelike and beautiful, with possibility of nudity through ornamentation.
Description
This utility model is a kind of artificial leg elastic surface closed porosity sleeve.Shortcomings such as its objective is to reach waterproof and dustproof, effect wear-resisting, attractive in appearance, it overcomes existing telescopic surface open micropore, non-watertight, dustproof, not wear-resisting, not attractive in appearance.Existing artificial leg configuration mainly is by receptive cavity 1, rigid backbone material 2, and joint 3, foot 4, sleeve 5 is formed.Sleeve is used light weight more, and the type shape is stable, and the macromolecular material of the open micropore of certain elasticity is arranged, and makes through grinding.Because bush material itself is open microcellular structure, is still open microcellular structure after the grinding molding, this artificial leg in use can run into multiple erosion medium resistance, as rainwater, vegetable soup, fruit juice, dust etc.; Also can run into the physical mechanical damage, as scratches such as wheelchair, furniture, wearing and tearing etc.And the surface is not attractive in appearance, can't be through decorating exposed outside.Existing sleeve through the grinding molding is by above-mentioned erosion medium resistance, and makes rigid metal framework material, joint corrosion, and physical mechanical damage and make the outer layer sleeve breakage is until making whole artificial leg lose serviceability.
This utility model designs in order to overcome above-mentioned shortcoming, and configuration is by receptive cavity 1, rigid backbone material 2, and joint 3, foot 4, the open micropore sleeve 5 of coating grinding molding, the flexible closed porosity layer 6 of sleeve surface is formed.The enclosed elastic microporous layers is the open microcellular structure in the telescopic surface of grinding molding to be sealed with the elasticity macromolecular material become closed structure.Thereby prevent matter Jie erosion, reduce physical abrasion, thereby increase its intensity and scratch-resistant performance at the damageable zone increase thickness that often rubs, and surperficial true to nature, attractive in appearance, can expose through decorating.
The elasticity macromolecule raw material that the open micropore of sealing is used can be used natural rubber, butadiene-styrene rubber, cis-butadiene cement, nitrile rubber, polyurethane rubber, CSM, EP rubbers.Add vulcanizing agent, promoter, age resistor, pigment, organic solvent are made the vulcanized latex of giving of rubber cement and above-mentioned rubber.Aforesaid liquid is coated on the sleeve surface of grinding molding, makes elastic surface closed porosity sleeve through heating sulfuration.
Embodiment 1: the open micropore sleeve of grinding molding is blown away surface impurity with hair-dryer.Make rubber cement with solid content 25% butadiene-styrene rubber, vulcanizing agent, promoter, age resistor, organic solvent, be coated on the outer layer sleeve surface with dipping method, with 50 ℃ of hot-air dries after 2 hours, soak again second time, 50 ℃ of hot-air dries of reuse 2 hours, and then with 143 ℃ of hot-air cures 15 minutes, 0.4 millimeter of the glue-line average thickness after the sulfuration of dipping secondary rubber cement.
Embodiment 2: the open micropore sleeve of grinding molding is blown away surface impurity with hair-dryer, the natural vulcanized latex of giving of 30% glue content is brushed in the outer layer sleeve surface with hairbrush, in 80 ℃ of hot-air cures 60 minutes, brush second road again, and then with 80 ℃ of hot-air cures 60 minutes, brush two roads, natural 0.6 millimeter of the vulcanizate average thickness that gives.If any the position need to strengthen, then can brush several roads again.
The elastic surface closed porosity layer physical and mechanical properties that two above-mentioned embodiment make is as follows:
Percentage elongation % 120
Hardness (Shao Shi) 8～10
Water-fast: as not see through in 168 hours
Anti-dilute hydrochloric acid did not see through in 4% 168 hours
Alkaline-resisting NaOH5% did not see through in 168 hours
Salt tolerant NaC110% did not see through in 168 hours
Ageing-resistant ozone concentration 50pphm, static 72 hours no breaches,
40 ± 1 ℃ of temperature
Claims (4)
1, a kind of artificial leg elastic surface closed porosity sleeve, configuration is by receptive cavity 1, rigid backbone 2, joint 3, foot 4 coats sleeve 5, elastic surface closed porosity layer 6 is formed, and it is characterized in that having the open micropore sleeve 5 through the grinding molding, elastic surface closed porosity layer 6.
2, the open micropore sleeve 5 through the grinding molding as claimed in claim 1 is characterized in that with elastic surface closed porosity layer 6 the open micropore sealing in its surface.
3, the material of elastic surface closed porosity layer 6 is a rubber organic solution according to claim 1, and rubber gives vulcanized latex.
4, sleeve 5 usefulness as claimed in claim 2 are brushed, spraying, and dipping method applies into elastic surface closed porosity layer 6.
