Abstract
A solidifiable gypsum bandage is proportionally prepared from setting retarder, cellulose dextrin, adhesive, solidifying time regulator and water through mixing, adding semi-hydrated calcium sulfate powder, stirring, coating, drying, cutting and winding.
Description
Technical field
The present invention relates to a kind of production method of binder, especially curable production of pypsum bandage.
Background technology
Plaster bandage is a kind of conventional products that medical industry is often used, be mainly used in the limbs repairing and treating, its production history is very long, in the modern society, the application of plaster bandage is constantly in expansion, as making footwear mould, animal model, house decoration, the petroleum pipeline wrapping, the student of academy of fine arts practises sculpture etc.The method of producing plaster bandage at present mainly contains two kinds, a kind of 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 the coating of Gypsum Fibrosum preparata (half water and calcium sulfate) mixed pulp and the gauze, as the patent No. is that 97115856.8 Chinese invention patent production of pypsum bandage adopts this process route, its advantage is that hardening time is stable, the intensity height, drying time is short, but shortcoming is to adopt methanol to make solvent, to direct labor's health particularly vision major injury is arranged, and workshop is easy to generate fire, causes life and property loss.Another kind is that calcium sulphate dihydrate (Gypsum Fibrosum) is joined in the solution of polymer, white glues and water composition, carry out drying on the gauze and cut through fully stirring to be coated on, the manufacture method that as the patent No. is 87100688 Chinese invention patent viscose plaster bandage adopts this process route, its advantage is that product is difficult for dry linting, easy to use, but shortcoming is that drying time is long, produce a large amount of heats, hardening time instability during curing, sometimes the phenomenon that eases back occurs, the danger that causes malpractice is arranged.Therefore, how to take into account the advantage of above-mentioned two kinds of methods and overcome the deficiency and produce plaster bandage and be one and press for the problem of researching and solving.
Summary of the invention
The purpose of this invention is to provide a kind of production of pypsum bandage, require to have that technology is simple, convenient for production, the advantage of stable performance and safety economy.
The objective of the invention is to realize by following technical scheme.
A kind of production of pypsum bandage of the present invention may further comprise the steps:
1 modulation polymer inorganic solution.
2 get that the calcium sulfate hemihydrate powder mixes according to a certain percentage with above-mentioned inorganic solution and fully stir and are modulated into the Gypsum Fibrosum preparata slurry.
3 introduce emulsion coating machine with gauze is coated on above-mentioned Gypsum Fibrosum preparata slurry on the gauze.
4 solutioning belts that will be coated with the Gypsum Fibrosum preparata slurry are introduced baking oven and are carried out drying, remove moisture.
5 cut the solutioning belt of oven dry, pack and become the plaster bandage product.
The described inorganic solution modulator approach of step 1 be with the binding agent of the cellulose dextrin of the retarder of 0-20 part, 4-20 part, 2-7 part, 0.4-2 part hardening time regulator and suitable quantity of water make that solution weight is 65-80 part; Step 2 is exactly the abundant furnishing Gypsum Fibrosum preparata slurries that stir of 100 parts of calcium sulfate hemihydrate powder warps of inorganic solution adding with step 1 preparation.Wherein said retarder can be one or more the combination in S type retarder, Borax, the citrate; Described binding agent can be a kind of of acrylate, methacrylate, polyacrylate, formic acid or polymethyl methacrylate, polyethyl methacrylate, vinyl acetate-ethylene copolymerization emulsions, polylauryl methacrylate, methyl methacrylate, methacrylic acid Laurel copolymer; Described hardening time, regulator can be a kind of in Alumen, potassium sulfate or the winestone pomegranate.
Because water is cooked solvent preparation inorganic solution among the present invention, does not need organic solvents such as methanol, has fundamentally solved problem of environmental pollution, avoided operator for a long time with the affected problem of methanol contact vision, eliminated the disaster hidden-trouble in workshop simultaneously; Add binding agent, can improve the fluidity of Gypsum Fibrosum mix in process of production, also can improve the intensity of plaster bandage, do raw material owing to adopt the calcium sulfate hemihydrate powder, in process of production, calcium sulfate hemihydrate powder in the slurry does not have moisture and sucks, behind the slurry drying, the physical bond effect that originally was scattered in the polymer molecule in the solution makes the gesso burl on the gauze synthesize membrane stratiform, so the Gypsum Fibrosum dust on the product is difficult for dropping, this and traditional method adopt gesso directly to spread and spread on gauze, Gypsum Fibrosum powder drop easily compare much superior, simultaneously, owing to adopt the gesso identical with traditional method, kept and stablized hardening time, the intensity height, it is few to produce heat during curing, the advantage that drying time is short, and adopt method of the present invention inorganic solution preparation and the preparation of Gypsum Fibrosum preparata slurry can be carried out together, need not the multiple tracks bucket stirs, simplified technology, by the addition of control regulator hardening time, can precisely control product hardening time, according to test, plaster bandage with a kind of production of pypsum bandage production of the present invention, dry powder drops less than 5%, wet-milling drops less than 4%, and heating is lower than 40 degree during curing, and hardening time, error was less than 0.5 degree.Therefore, the present invention has a kind of production of pypsum bandage, has that technology is simple, convenient for production, an advantage of stable performance and safety economy.
