Description
Technical field
The present invention relates to a kind of zeolite medical bandage, relate in particular to the medical bandage that is added with firming agent, promoter, reinforcing agent in a kind of zeolite powder, belong to field of medical article technology.
Background technology
Plaster bandage is a kind of conventional products that medical industry is often used, and is mainly used in limbs bone injury repairing and treating, and its production history is very long.The method of traditional production plaster bandage is mainly to adopt Inorganic Chemicals to be mixed and made into solution with organic solvents such as industrial methanols be dried and to cut again with on the coating of Gypsum Fibrosum or Gypsum Fibrosum preparata mixed pulp and gauze, as the patent No. this process route of Chinese invention patent production of pypsum bandage employing that is 97115856.8.But traditional medical plaster bandage has obvious shortcoming, such as ventilative, poisture-penetrability is poor, hardening time is unstable, drying time is long, it is unstable to meet water intensity, even easily makes patient's burn wound because produce large calorimetric in the short time in the time of wrapping.Due to ventilative, that poisture-penetrability official post must be wrapped up aftersensation is vexed; and the skin of wrapping place can turn white and itches; meet water intensity unstable main manifestations and be after plaster bandage wraps up and harden, run into the mechanical strength that water can make it to maintain and significantly reduce, be unfavorable for the protection to patient injury.
Summary of the invention
The object of the invention is for solving the problems of the technologies described above, a kind of zeolite medical bandage is provided.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
A kind of zeolite medical bandage, by zeolite crystal powder, firming agent, mould the materials such as solidifying agent, rubber polymer and gauze and make by coating, roll-in, wind baking, rolling, separating and cutting process; In zeolite crystal powder, be added with firming agent more than 120 orders of 30～70wt%, the hardening agent of moulding solidifying agent and 0.2～2wt% of 0.2～2wt%, the rubber polymer of 0.2～2wt%; Described zeolite can pass through 60～250 object standard screens.
Zeolite chemical composition General Expression is M

2o.Zeolite is a kind of molecular sieve take silicon (aluminum) oxygen tetrahedron as the spacious silica screen work of having out of basic structural unit, [SiO
4]
4-in Si be SP3 hydridization, be tetrahedral structure, silicon (aluminum) atom occupies tetrahedral center, four oxygen atoms are positioned at tetrahedral four drift angle .[Si-O] bond distance is 0.162 nm, [O-O] bond distance is 0.264 nm.Because the character of aluminum is similar to silicon, aluminum atom can replace silicon atom and form aluminum-oxygen tetrahedron [AIO
4]
5-, wherein [Al-O] bond distance is 0.175 nm, [O-O] bond distance is 0.286nm.Silicon-oxy tetrahedron interconnects by the oxygen atom in tetrahedron top, forms circulus tandem array, hollow, forms silicon (aluminum) oxygen tetrahedral group, becomes the skeleton of zeolite.Silicon (aluminum) the oxygen framing structure of this spaciousness, has bug hole, geode and the duct of many marshallings, makes zeolite have stronger cation exchange property and absorption property.In the process of hydrated cementitious, hydrone will be full of the whole skeleton of zeolite.Cation in grog in free calcium ion or other ions and zeolite exchanges, to there is the variation of " dealuminzation-solution silicon-knot calcium " under certain condition in silicon (aluminum) the oxygen skeleton of zeolite, make zeolite can increase the stability of Gypsum Fibrosum and increase tension, comprcssive strength.This is also the main cause that will add the coagulant of 0.2～2wt% in gypsum powder.This coagulant is alkaline metal salt or alkaline-earth metal salt.
The framing structure of zeolite also makes zeolite have stronger absorption property and permeability.Therefore, be added with after zeolite, making the present invention can effectively solve conventional gypsum binder because the airtight stuffy difference sense of itching bringing.Due to the stronger absorption property of zeolite, Gypsum Fibrosum is in the process of aquation, and hydrone will be full of the whole skeleton of zeolite.To Gypsum Fibrosum, moulding curing early stage maintenance is a large advantage for this.Traditional plaster bandage needs water in use, water makes calcium sulphate powders become calcium sulphate dihydrate, the Gypsum Fibrosum of calcium sulphate dihydrate form is beneficial to moulding, meanwhile can produce heat, heat makes Gypsum Fibrosum become half-H 2 O calcium sulphate form from calcium sulphate dihydrate Morphological Transitions, and half-H 2 O calcium sulphate form Gypsum Fibrosum has very strong hardness.The subject matter of conventional gypsum binder is can produce at short notice large calorimetric in Gypsum Fibrosum hydration process, and this is easy to injury to damage.And usually because aquation not exclusively makes the lower hardness of plaster bandage.And the present invention in use, part water participates in hydration, another part water is just transferred in the hole of zeolite, being present in speed that water in zeolite space not only can limit hydration makes the thermal discharge can be too unconcentrated, can also make Gypsum Fibrosum hydration more thorough, improve the intensity of Gypsum Fibrosum.What is more important, traditional plaster bandage after its sclerosis, meet after water its intensity can decline 50% even more than, this is very unfavorable for mainly shielding.And in the present invention, when after Gypsum Fibrosum sclerosis, zeolite is present in Gypsum Fibrosum tissue, after Gypsum Fibrosum is met water, its moisture is absorbed by zeolite, and the impact that Gypsum Fibrosum is produced is little.Therefore, in the present invention, be added into Gypsum Fibrosum powder and can also play intensity cushioning effect.But also make Gypsum Fibrosum become loose adding of zeolite, adhesion strength reduces, and is difficult for solidifying, and therefore in the present invention, also needs to be added into a small amount of coagulant and hardening agent simultaneously.
Take zeolite as main dielectric material, significantly strengthen on the one hand the intensity after binder sclerosis in the present invention, along with the intensity after the rising binder sclerosis of zeolite ratio also can slowly reduce, continue to increase the amount of inserting even also low than the intensity of not adding zeolite on the other hand; But in the time that the addition of zeolite is on the low side, the effect of air-moisture-permeable is not remarkable.Therefore in order to guarantee that technique effect the present invention of the present invention takes zeolite addition 30～70wt%, coagulant addition 0.2～2wt% and hardening agent addition 0.2～2wt%, and zeolite particle diameter is controlled at by 60～250 object standard screens.
The addition of zeolite and its granularity are to permeability, and water permeability and protection strength character are vital.Draw, in the time that the addition of zeolite is defined as 30～70wt%, to have significantly ventilative, permeable, dehumidifying effect through inventor's research, in the time that addition exceedes 70wt%, the intensity of plaster bandage just cannot reach requirement.The air permeable effect of the larger binder of granularity of same zeolite is more obvious, but its intensity can reduce simultaneously.In sum, when the addition of described zeolite is 30～70wt%, when described zeolite can pass through 60～250 object standard screen, can control well quality of the present invention.
As technique scheme preferably, the addition of described zeolite is 40～60wt%, described zeolite can pass through 120～250 object standard screens.
As technique scheme preferably, described coagulant is one or more in sodium sulfite, sodium silicate, calcium chloride and calcium oxide, described hardening agent is one or more in triethanolamine, glycerol or diethylene glycol.
As technique scheme preferably, in described Gypsum Fibrosum powder, be also added with the softening agent of 0.1～1wt%.
As technique scheme preferably, described softening agent is that general formula is (RCOO
-)
nm
n+salts substances, wherein R is C
11～C
17.
In sum, the present invention has following beneficial effect:
The present invention has moisture-penetrable ventilated technique effect.And the present invention can not make patient injured because producing large calorimetric in the short time in use; In addition, traditional plaster bandage is met its intensity of water and is significantly declined, and plaster bandage of the present invention is under to a certain degree, meets its intensity of water unaffected.
