Embodiment
The present invention is described further with reference to embodiment.The explanation of following embodiments is only intended to help and understands this
Invention.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, also
Some improvement and modification can be carried out to the present invention, these are improved and modification also falls into the protection domain of the claims in the present invention
It is interior.
As shown in Figures 1 to 5, this solid rubber cylinder, including：Outer layer lid 1, internal layer cap 2, the and of solid glue stick 9
Solid rubber cylinder 10, the internal layer cap 2 is located in outer layer lid 1 and can be rotatable relative, and outer layer lid 1 is provided with sector
Opening 12, the independent inner chamber of the correspondence sector open 12 of internal layer cap 2 provided with three groups of perforates and one group of non-perforate, by 1/
4 circles separate；The lower section of internal layer cap 2 is provided with thermally conductive sheet 11, and the lower section of thermally conductive sheet 11 is provided with sodium bicarbonate particle 7 and permeable
Gauze layer 8, the permeable correspondence of gauze layer 8 solid glue stick 9；The internal layer cap 2 includes breathing waterproof film 3, polymer 4, leech
Stone 5 and ventilated membrane 6.The polymer 4 is iron powder, charcoal, sodium chloride and the crystal group being hydrated.The thermally conductive sheet 11 is thin
Copper sheet or aluminium foil.The sodium bicarbonate particle 7 and permeable gauze layer 8 are on mesh plate.
Internal layer cap 2 is hollow structure, and uniform hole is dispersed with 3/4 area of two end faces above and below it.It is interior
The hollow inside of layer cap 2 is placed with breathing waterproof film 3, polymer 4, vermiculite 5 and ventilated membrane 6.Polymer 4 be iron powder,
Charcoal, sodium chloride and the crystal group being hydrated.Vermiculite 5 is a kind of silicate, with aeration, water conservation and insulation effect, is subtracted
Slow radiating rate.Breathing waterproof film 3 is the waterproof ventilative material of spunbond polypropylene composite materials high molecular polymer, product tool
There are good water proofing property, gas permeability.Ventilated membrane 6 can prevent polymer powder from overflowing.Place thin copper in the bottom of internal layer cap 2
Piece, scale copper has good thermal conductivity, and its thermal conductivity is 401W/m-K, compared with the heat conductivility of the metal materials such as aluminium, gold, iron
It is good.Sodium bicarbonate particle 7 is wrapped up by permeable gauze layer 8.Usually the hole of internal layer cap 2 is closed by outer layer lid 1, is kept
The sealing of cover, it is to avoid iron powder and air contact.
Needing to heat glue stick and during moisturizing, internal layer cap 2 is being rotated by 90 °, air is rotated by internal layer
The upper end hole of lid 2 enters.Oxygen in air reacts through breathing waterproof film 3 with polymer 4, produces heat.Bicarbonate
Sodium powder end is heated to decompose, and produce moisture and carbon dioxide, form a small amount of steam and aqueous.Carbon dioxide has insulation
Function.
It can be terminated and chemically reacted by reverse 90 degree rotation internal layer cap 2.Can also by 180 degree again or
270 degree of rotation internal layer cap 2, are chemically reacted next time.
When needing to recover solid adhesivity, 90 degree of rotation internal layer cap 2, the hole of internal layer cap upper surface
Exposure is in atmosphere.Oxygen in air is aoxidized through the polymer 4 inside breathing waterproof film 3, with internal layer cap 2
Reaction.Reverse 90 degree of rotation internal layers cap 2, can be with cap holes terminating reaction.The control of chemical reaction is revolved by internal layer
Hub cap 2 is carried out so that related chemistry reaction can repeatedly occur in the case of controllable.
Oxygen enters polymer 4 and the mixed layer of vermiculite 5 through breathing waterproof film 3, and vermiculite has a gas permeability, polymer 4 with
After vermiculite mixing, the contact area of polymer 4 and oxygen becomes big.Vermiculite 5 is a kind of silicate and has water-retaining property, to oxidation of iron powder
There is certain catalytic action, the oxidation heat liberation of iron powder in polymer can be accelerated.
Iron powder in polymer 4 occurs oxidation reaction with oxygen and produces heat.Sodium chloride and water are that oxidation of iron powder reaction is fast
The Effective medium that speed occurs.There are a large amount of hollow and uniform holes on wooden carbon particle surface, and the oxidation heat liberation of iron powder can be helped to protect
Hold uniform speed.The temperature of iron powder heat release can reach 60 DEG C or so.
Close after the hole of internal layer lid 2, under the insulation effect of vermiculite 5, temperature can be still maintained within a period of time.
The decomposition temperature of sodium acid carbonate 7 is 60 DEG C or so, starts gradually to decompose after heated:2NaHCO3=△=Na2CO3+H2O+CO2
↑.The chemical reaction produces the vapor adhesion of warm on the surface of solid gum 9 of solidification.
After oxidation reaction is carried out 5-10 minutes, 290 degree of internal layer cap can be reversely rotated, its upper surface is closed
Hole.In the space that solid rubber cylinder 10 is closed, 60 DEG C or so of temperature is maintained, and has the moisture warmed on a small quantity.Solid glue stick 9
Surface is absorbed moisture to recover viscosity by continuous heating.
When the temperature of outer layer lid 1 is gradually reduced, outer layer lid 1 can be turned on, at this moment can use and recover viscosity
Solid gum.
When solid gum places more long, when losing viscosity again, internal layer cap 2 can be rotated to 180 degree or 270 degree,
New chemical reaction once is carried out, helps solid gum to recover viscosity.
