According to the present invention, the wide carbon dioxide sealing and storage market is provided for the carbon dioxide pollution reduction.
Description
Technical field
The present invention relates to a kind of air spring of sofa cushion and making apparatus thereof and preparation method, this air spring is that one can sequestration of carbon dioxide in a large number, has comfort cushioning performance and has the environment-friendly products of fire-fighting function.
Technical background
Along with the demand of the mankind to the energy is increasing, in air, the ratio of carbon dioxide is more and more higher, and carbon dioxide isothermal chamber gas more and more threatens the living environment of the mankind.We need the approach finding more storage carbon dioxide.But now sequestration of carbon dioxide high cost and means are abundant not, be not enough to the discharge ratio slowing down carbon dioxide.
On the other hand, the metal spring that cushion pad in sofa in the market adopts and foam combines or adopt separately foam as elastomeric cushion material, its inflammable feature makes residence at home lack security against fire sense.
Summary of the invention
The present invention provides a kind of air spring of sequestration of carbon dioxide for solving carbon dioxide problem, described air spring is used for sequestration of carbon dioxide and utilizes the elastic compression of carbon dioxide and fire-fighting function to help the sofa of this air spring of filling or other furniture to promote practicality and security.The present invention illustrates for sofa.
The present invention is by following technological means sequestration of carbon dioxide:
The present invention includes a kind of air spring for sequestration of carbon dioxide, and for making the equipment of air spring, and make the method for air spring.
A kind of air spring of the present invention, comprises the air spring body for cushioning, and for retraining the Fibre Bag of air spring body, and for the support frame that supports people and sofa overcoat.
Multiple air spring body is packaged into through Fibre Bag and is arranged between the backrest of support frame and overcoat after air cushion and between the seat board of bracing frame and seat surface, to substitute traditional metal spring or foam carpet.
Further, described air spring body comprises just tire and protective layer, and described just tire and protective layer adopt the good plastics of air-tightness or rubber and fiber composite to be made.Described just tire is combined by the rectangular cells of two standards, the inside of described rectangular cells is provided with the traction-resistant fibre that the constraint position for limiting air spring body expands outwardly, one end of described traction-resistant fibre is connected with the containment surfaces at constraint position, place, and the other end is connected with the containment surfaces on its opposite.Described traction-resistant fibre should perpendicular to place containment surfaces, not give by two containment surfaces extension spaces of its restriction.
Further, the joint portion of described two rectangular cells is provided with fiber cloth, described fiber cloth is connected with the periphery at the constraint position of two rectangular cells, after being combined into the first tire of an air spring body to make two rectangular cells, can not there be the space of outwards extending the middle part at its constraint position, the constraint strength of further increase air spring body, and then the practicality and the durability that improve air spring body.
Further; the outer surface cover matcoveredn of described just tire; described protective layer used in first tire being wrapped up and sealing, compensate for the intensity of the joint portion of two rectangular cells with the air-tightness further strengthening just tire simultaneously, strengthen practicality and the durability of air spring body.Described protective layer comprises for holding just the protection chamber of tire and the over cap for the import of seal protection chamber.
A kind of mould making rectangular cells
The mould making rectangular cells comprises modular unit and forming unit two parts.The fibrolaminar unit fibers bag that described modular unit is used for fixing rectangular cells is also provided with the seam entered for traction-resistant fibre therein, and described forming unit is compounded to form rectangular cells for holding modular unit and being formed with injection moulding cavity with the ready plastics of injection and fibrage after combining with modular unit.Described fibrage comprises the traction-resistant fibre of the unit fibers bag of the plies intensity for strengthening rectangular cells and the ductility for restriction position.
A kind of production line combining rectangular cells
The production line of combination rectangular cells comprise mould forming unit and for the expanded support parts by two rectangular cells expanded supports, and for filling in two rectangular cells, there is the operating room of the gas of certain purity.
Described expanded support parts be vacuum absorption device or other type for by the plies of rectangular cells from outside by the device that rectangular cells is expanded, to facilitate combination.
Described operating room has good air-tightness and has certain compression strength, is furnished with air-extractor and charger.Described air-extractor is used for the air in operating room to be evacuated, and described charger is used for the carbon dioxide of filling certain pressure in operating room.Air cushion due to sofa needs certain elastic buffer function, and in first tire, the pressure of gas must be greater than atmospheric pressure guarantee elasticity, therefore needs operating room to have and good bubble-tightly has certain compression strength simultaneously.If what rectangular cells adopted is that thermoplastic and fiber composite are made, then expanded support parts are provided with the heater for fusing.
A kind of sealing device wrapping up just tire
