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 mainly is to adopt Inorganic Chemicals to be mixed and made into solution with organic solvents such as industrial methanols to carry out drying and cut again with on Gypsum Fibrosum or the coating of Gypsum Fibrosum preparata mixed pulp and the gauze, is that 97115856.8 Chinese invention patent production of pypsum bandage adopts this process route like the patent No..But traditional medical plaster bandage has significant disadvantages, such as ventilative, poisture-penetrability is poor, hardening time is unstable, drying time is long, it is unstable to meet water intensity, even makes patient's burn wound easily because when wrapping, produce big calorimetric in the short time.Because ventilative, that the poisture-penetrability official post must be wrapped up aftersensation is vexed; And the skin of wrapping place can turn white and itches; Meet after water intensity instability mainly shows as plaster bandage wrapping and sclerosis, run into the mechanical strength that water can make that it can be kept and significantly reduce, be unfavorable for protection the patient injury.
Summary of the invention
The objective 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 through following technical scheme:
A kind of zeolite medical bandage is by zeolite crystal powder, firming agent, mould with fixed attention that materials such as agent, rubber polymer and gauze make through coating, roll-in, wind baking, rolling, separating and cutting process; Be added with the above firming agent of 120 orders of 30～70wt% in the zeolite crystal powder, the hardening agent of moulding agent with fixed attention and 0.2～2wt% of 0.2～2wt%, the rubber polymer of 0.2～2wt%; Said zeolite can pass through 60～250 purpose standard screens.
The zeolite chemical composition generally is expressed as M
2O
nAl
2O
3XSiO
2YH
2O.Zeolite be a kind of be the molecular sieve of the spacious silica screen work of having out of basic structural unit with silicon (aluminum) oxygen tetrahedron, [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 angles. [Si-O] bond distance is 0.162 nm, and [O-O] bond distance is 0.264 nm.Because the character of aluminum is similar with silicon, aluminum atom instead silicon atom forms 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 through the oxygen atom that is in tetrahedron top, forms circulus tandem array, hollow, constitutes silicon (aluminum) oxygen tetrahedral group, becomes the skeleton of zeolite.The silicon of this spaciousness (aluminum) oxygen framing structure, bug hole, geode and duct with many marshallings make 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 the grog in free calcium ion or other ions and the zeolite exchanges; The variation of " dealuminzation-separate silicon-knot calcium " will take place under certain condition in the silicon of zeolite (aluminum) oxygen skeleton, make stability that zeolite can increase Gypsum Fibrosum with increase tension, comprcssive strength.This also is the main cause that will in gypsum powder, add the coagulant of 0.2～2wt%.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, after being added with zeolite, make the present invention can effectively solve the conventional gypsum binder because the airtight stuffy difference sense of itching that brings.Because 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.Moulding solidified early stage maintenance is a big advantage to Gypsum Fibrosum for this.The conventional plaster binder 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 be transformed into the half-H 2 O calcium sulphate form from the calcium sulphate dihydrate form, and half-H 2 O calcium sulphate form Gypsum Fibrosum has very strong hardness.The subject matter of conventional gypsum binder is can produce big calorimetric at short notice in the Gypsum Fibrosum hydration process, and this is easy to the injury is damaged.And usually because aquation not exclusively makes the hardness of plaster bandage reduce.And the present invention in use; Part water is participated in hydration; Another part water is just transferred in the hole of zeolite; Be present in the speed that water in the zeolite space not only can limit hydration and make that thermal discharge can be too unconcentrated, can also make the Gypsum Fibrosum hydration more thorough, improve the intensity of Gypsum Fibrosum.What is more important, conventional plaster binder after its sclerosis, meet behind the water its intensity can descend 50% in addition more than, this is very unfavorable for mainly shielding.And among the present invention, after the Gypsum Fibrosum sclerosis, zeolite is present in the Gypsum Fibrosum tissue, and its moisture was absorbed by zeolite after Gypsum Fibrosum was met water, and is little to the influence that Gypsum Fibrosum produces.Therefore, be added into Gypsum Fibrosum powder among the present invention and can also play the intensity cushioning effect.But the adding of zeolite also makes Gypsum Fibrosum become loose simultaneously, and adhesion strength reduces, and is difficult for solidifying, so also need be added into a spot of coagulant and hardening agent among the present invention.
Be main dielectric material with zeolite in the present invention, significantly strengthen the intensity after binder hardens on the one hand, 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 lower on the other hand than the intensity of not adding zeolite; But when the addition of zeolite was on the low side, the effect of air-moisture-permeable was 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 the zeolite particle diameter is controlled at through 60～250 purpose standard screens.
The addition of zeolite and its granularity are to permeability, and water permeability is vital with the protection strength character.Draw through inventor's research, when the addition of zeolite is confirmed as 30～70wt%, have significantly ventilative, permeable, dehumidifying effect, when addition surpassed 70wt%, the intensity of plaster bandage just can't reach requirement.The air permeable effect of the big more binder of granularity of same zeolite is obvious more, but its intensity can reduce simultaneously.In sum, when the addition of said zeolite is 30～70wt%, when said zeolite can be through 60～250 purpose standard screens, can control quality of the present invention well.
Preferred as technique scheme, the addition of said zeolite is 40～60wt%, said zeolite can pass through 120～250 purpose standard screens.
Preferred as technique scheme, said coagulant is one or more in sodium sulfite, sodium silicate, calcium chloride and the calcium oxide, said hardening agent is one or more in triethanolamine, glycerin or the diethylene glycol.
Preferred as technique scheme also is added with the softening agent of 0.1～1wt% in the said Gypsum Fibrosum powder.
Preferred as technique scheme, said softening agent is that general formula is (RCOO
-)
nM
N+Salts substances, wherein R is C
11～C
