Description

A kind of concertina type composite double layer packing element

Technical field

A kind of concertina type composite double layer packing element is the utility model is related to, it is more particularly to a kind of using the compound of concertina type cylinder Double-deck packing element.

Background technology

Glass cement is the material that various glass and other base materials are bonded and sealed, and is broadly divided into two major classes：Silicone Glue and polyurethane adhesive.Silicone sealant is exactly our usually said glass cements, is divided into again acid and neutral two kinds；Neutral silicone Fluid sealant is divided into sealant for stone material, mildewproof sealant, fireproof seal gum etc. again.

The downstream application of glass cement is mainly the industries such as curtain wall decoration, house ornamentation, and main component is organic silicon rubber, titanium dioxide Silicon, calcium carbonate and crosslinking agent etc..Promoted with the acceleration of Urbanization Process In China, construction scope, Old building safeguard regeneration area Constantly expand, building function, finishing class gradually step up, and account for the silicone sealant demand of the building sealant market share 40% Amount is by sustainable growth, especially in the engineerings such as building energy conservation, waterproof, decorations and building curtain wall, before having good development Scape, it is contemplated that the year two thousand twenty silicone sealant demand is up to 20.9 ten thousand tons.Usage amount, the demand of silicone sealant packaging material Greatly.

The structure glue of the existing flexible glue barrier packaging in market, because its good seal performance, product do not allow it is perishable, mainly as glass The high-end kind of glue is used by the special large-scale glue spraying gun comprising packing element, but because its cost is higher, in-convenience in use, must match somebody with somebody Standby special glue spraying gun.Existing length-specific soft gum tube suitably supports the use with the ebonite cylinder of corresponding length, ebonite cylinder it is general Property is substantially inadequate.

At present, the disposable hard packing element duricrust packaging quantity abandoned every year causes greatly to provide up to more than 1,000,000 tons Source wastes, environmental pollution.The advantages of ebonite cylinder is easy to use；Shortcoming is that sealing property requires high, and its bottom, which needs to have, exhales Function is inhaled, just adapts to the change of environment temperature, thus the material of manufacture processing and required precision are high；Bottom can only be transported unidirectionally It is dynamic, thus be only capable of using as disposable products；Due to factors such as temperature, deformations, gas leak phenomenon, thus pole easily occur for bottom It is easily caused glass colloidin；Consumable material is more, and the packing element of identical amount of fill is compared, and soft gum tube saves 70% material compared with plastic cement shell ring Material, the material cost of plastics ebonite cylinder are higher；Plastics ebonite cylinder discarded object belongs to environment non-degradable thing, the dirt to natural environment Contaminate, be very harmful；The sorting and collection of ebonite cylinder are, it is necessary to expend substantial amounts of human and material resources, financial resources and transport resource；Ebonite cylinder Processing procedure need to consume substantial amounts of resource, produce the material harmful to human body and environment.

Therefore how to solve the above-mentioned problems of the prior art, with reference to hard, soft gum tube respective advantage, eliminate ebonite cylinder Soft gum tube length change this problem can not be adapted to, turns into the difficult point of the area research.

The content of the invention

The utility model is to solve the problems, such as that prior art is present, there is provided a kind of concertina type composite double layer packing element, is used Scalable packing element and hard soft gum tube complex technique, the versatility of ebonite cylinder is improved, reach the optimization of packing element overall performance, significantly drop Low use cost, glass cement packaging waste yield, the mesh as energy saving and environment friendly resource-conserving product is greatly lowered 's.

The purpose of this utility model is achieved through the following technical measures：

A kind of concertina type composite double layer packing element, it is characterised in that：

Described concertina type composite double layer packing element includes ebonite cylinder, soft gum tube；Described ebonite cylinder includes flexible cylinder, envelope Head and bottom；Described soft gum tube is equipped with glass cement and is positioned over inside ebonite cylinder；Described end socket is with ebonite cylinder using removable Unload connected mode.

Described flexible cylinder refers to that cylinder is made of bellows or bellows, both ends connection pipe joint.

The pipe joint at described flexible cylinder both ends is used as the length of guide rail regulation ebonite cylinder by two telescopic levers.

Described end socket is referred to using screw thread, buckle, clamshell combination buckle with ebonite cylinder using detachable connection Etc. connected mode.

Described end socket is provided with gum outlet, end socket is opened during use, seal on soft gum tube, is closed again end socket and ebonite cylinder Hollow out cylinder, bottom is promoted by drive device, so as to reach the purpose of applying glue operation.

Described soft gum tube fills glass cement, sealing is intact and is bonded closely with the scalable cylinder of ebonite cylinder.

Described end socket is identical with flexible cylinder internal diameter.

Flexible cylinder, bottom and the end socket of described ebonite cylinder use metal or nonmetallic composite.

Described soft gum tube uses aluminum-plastic composite membrane.

The unaccounted technical characteristic of the utility model is carried out supporting using existing known packing element technology.

The utility model has the following advantages that compared with prior art：

1st, compared with existing disposable hard packing element, the manufacture of bottom and requirement reduce, flexible and convenient to use, and can be anti- It is multiple to use repeatedly；Telescopic cylinder adapts to the soft gum tube of different length, and the versatility of ebonite cylinder is remarkably reinforced；

2nd, it is hard in composite double layer packing element because the iris action of soft gum tube, abrasion of the glass cement to ebonite cylinder considerably reduce The service life of packing element greatly extends；

3rd, because the ebonite cylinder of concertina type composite double layer packing element can be reused many times, the comprehensive packaging material being intended for single use Cost is remarkably decreased, and is effectively saved cost；

4th, there is reliable guarantee compared to disposable hard packing element, the quality of glass cement, construction quality and production has been effectively ensured Quality；

5th, using technology of the present utility model, Chinese festiva glass cement duricrust discarded object decrement up to more than 940,000 tons, The reduction effect connect is more prominent, has saved substantial amounts of human and material resources, financial resources, economic, society, obvious environment benefit；

6th, contribute to establish resource-conserving, energy saving and environment friendly society, product has broad application prospects.
