Description
Technical field
The invention belongs to bottle cap technical field, be specially a kind of bottle cap sealing pad.
Background technology
Gasket seal is a kind of sealing member for fluids such as container, machinery, equipment, pipelines, the material sealed.Gasket seal is with metal or non-metal tabular material, and through cutting, the technique such as punching press or cutting is made, for being tightly connected between pipeline, between the parts of equipment and parts, and the sealed package etc. of flask.Metallic packing and non-metal gasket seal can be divided into by material.Metal have copper backing, stainless steel gasket, iron gasket, aluminium backing etc.Nonmetallic have asbestos gasket, non-asbestos pad, paper packing, rubber sheet gasket, pourable resin chock etc.
In daily life, food packaging bottle generally all needs sealed package, adopts and configure gasket seal to realize the object sealed in bottle cap.For papery gasket seal, frangible, soak in a liquid, sealing effectiveness is poor, and can not reuse.Using the high-molecular organic material such as plastics, rubber as gasket seal or as gasket seal base material, as taken polystyrene as the blowing paper gasket seal of raw material, very easily fracture; Short with the gasket seal Sealing period that polyethylene, polyvinylchloride are base material, when seal failure, sealing compensation can not be carried out, especially in the application of the seal aspect of some volatile substances, as alcoholic beverage, fizz etc., through beverage after a while concentration, great changes will take place for mouthfeel; Some bottled material, with acid, alkaline, has corrosive property to gasket seal; The gasket seal of hot compound press polish one, employing polystyrene is base material, by the film such as polyethylene, polyvinylchloride and the hot compound press polish one of base material, although improve the toughness of gasket seal, leak tightness, not frangibility, but polyethylene, polyvinylchloride etc. in food stage gasket of bottle lid material, need to add 40% ~ 60% plasticizer to improve its processing characteristics in this type of gasket seal is produced, add aging inhibitor and improve in-use performance, wherein phthalate plasticizers enter human body enrichment can teratogenesis, carcinogenic.Therefore, in the gasket seal being available for users to select, it is very limited for having multi-functional gasket seal, researchs and develops functional gasket seal that is strong, good seal performance and has great importance.
Summary of the invention
The object of the invention is to overcome shortcomings and deficiencies of the prior art, provide a kind of good seal performance, intensity high, the multi-funcitonal bottle top gasket seal of flexible sealing can be realized.
The present invention adopts inorganic polymer fiber as the base material of gasket seal.Carbon fiber be carbon content higher than 90% inorganic polymer fiber, axial strength and the modulus of carbon fiber are high, density is low, higher than performance, without creep, and superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, specific heat and electric conductivity are between non-metal and metal, and thermal expansion coefficient is little and have anisotropy, good corrosion resistance, X-ray transparent is good, not containing plasticizer, aging inhibitor etc.Therefore, select carbon content higher than 90% inorganic polymer fiber as seal gasket for bottle cap base material, intensity is high, corrosion stability is strong, high temperature resistant, not easily aging, high comprehensive performance.
At the two-layer polytetrafluoroethylene of base material coated on both sides.Because carbon fiber is oxidized under strong acid effect, if bottled food is highly acid material, gasket seal is easily by acid oxidase, if bottle cap material is metal simultaneously, metallic carbide, carburizing and electrochemical corrosion phenomenon being there is with its compound tense, in order to improve the performance of bottle cap sealing pad, preventing base material from sealing needs when bottled food is acidic materials, at base material coating on both sides one deck polytetrafluoroethylene, the thickness contacting bottled material side is two times of opposite side thickness.
Utilize elastic silica gel to strengthen adhesive ability between gasket seal and bottle cap, strengthen sealing property, realize the pretension of gasket seal, compensation effect.Polytetrafluoroethylene is generally called " non-sticking lining ", is a kind of synthesized polymer material using fluorine to replace all hydrogen atoms in polyethylene.This material has the feature of antiacid alkali resistant, anti-various organic solvent, is dissolved in all solvents hardly.Meanwhile, polytetrafluoroethylene has resistant to elevated temperatures feature, and does not resemble polyvinylchloride gasket seal goods and will decomposite harmful hydrogen chloride gas at leisure at relatively high temperatures.But its friction coefficient is extremely low, as gasket seal, with bottle cap side poor adhesive force, after opening bottle cap, gasket seal easily comes off, for this reason, apply the nontoxic elastic silica gel of one deck contacting side with bottle cap, for increasing the adhesive ability between gasket seal and bottle cap, be close to side with bottle cap and make pitted skin, the gasket seal outer rim contacted with bottle cap is waveform elastic silica gel, elastic silica gel is to gasket seal outer rim inside gasket seal and sealing bottleneck contact position, gasket seal and bottleneck contact position, according to bottleneck shape and bottleneck wall thickness, the groove matched with it is set, bottleneck edge card is in groove, in order to strengthen the airtight performance of gasket seal, utilize the elastomeric property of elastic silica gel to realize pretension and the compensation effect of gasket seal simultaneously.Be still polytetrafluoroethylene with material contact layer in bottle in pad, with bottleneck realize sealing be elastic silica gel and and elastic silica gel on groove.
Be close to side with bottle cap and gasket seal outer rim is elastic silica gel, and gasket seal and bottle cap are close to the pitted skin of side, are at 1cm
2elastic silica gel is arranged 30-40 pitting or projection, object is the friction force increasing the bottle cap such as pad and metal, prevents pad from coming off when opening bottle cap.
Seal gasket for bottle cap of the present invention is by force functional, can be applied on the bottle cap sealing such as bottled food, chemical substance, has good beneficial effect.There is very high intensity, can repeatedly use; There is high sealing performance, seal when can realize article long-time storage, ensure the quality of article; Utilize the high resiliency of elastic silica gel can realize pretension and the stretch compensation of gasket seal; Gasket seal material is without the harmful plasticizer of Phthalates and aging inhibitor; There is corrosion stability.
Accompanying drawing explanation
Accompanying drawing 1 is seal gasket for bottle cap structural representation; Accompanying drawing 2 is seal gasket for bottle cap cross section structure figure.
Diagram: 1 waveform elastic silica gel, 2 circular grooves, 3 pitted skins, 4 polytetrafluoroethylenes, 5 inorganic polymer fibers, 6 elastic silica gels, 7 grooves, 8 polytetrafluoroethylenes.
Detailed description of the invention
Seal gasket for bottle cap as shown in the figure, gasket seal is circular, inorganic polymer fiber 5 is base material, descend the two-layer polytetrafluoroethylene 4 of coating on both sides thereon, the thickness of side is 2 times of opposite side thickness, single times of thickness side and contact with bottle cap gasket seal outer rim coating elastic silica gel 6, single times of thickness side elastic silica gel makes pitted skin 3, and this face contacts with bottle cap.Pitted skin is at 1cm
2elastic silica gel is arranged 30-40 pitting or projection; The elastic silica gel of the gasket seal outer rim contacted with bottle cap makes waveform elastic silica gel 1.In the side of 2 times of thickness, be starting point, the elastic silica gel of gasket seal outer rim makes groove 7 from polytetrafluoroethylene 8 and elastic silica gel 6 contact surface, the shape of groove and the bottleneck for sealing mate, in concavo-convex collocation shape.
Seal gasket for bottle cap of the present invention can adopt precision processing technology and mould to produce.
