The waterproof protective material is printed on the surface of a pressure steam sterilization chemical indication color-changing agent by a silk screen to form a waterproof protective film, the pressure steam sterilization chemical indicator with the waterproof function is manufactured, and the indicator has the waterproof function and does not influence normal color change of the pressure steam sterilization indicator.
Description
technical field
The invention belongs to medical facilities technical field, be specifically related to a kind of waterproofing protection material, relate to the pressure steam sterilizing chemical tracer card that a kind of this waterproofing protection material is made simultaneously.
background technology
Method of pressure steam sterilization is one of sterilising method that medical and health organization and medical instruments manufacturing enterprise are generally used both at home and abroad at present.Method of pressure steam sterilization has that sterilizing ability is strong, the cycle is short, cost is low, simple to operate, use the features such as safe, pollution-free, be one of most widely used general, effective means in thermodynamics sterilizing.
Pressuresteam sterilization indicating card is the conventional indicating card of detecting pressure steam sterilizing effect.In same autoclave sterilizer, under the conditions such as identical pressure, temperature, time, because Packaging Method is different with packing content thing, often occur that the variable color of pressuresteam sterilization indicating card is inhomogeneous or be shallower than the phenomenon of reference colour, thus the judge of impact to sterilising effect.Causing pressuresteam sterilization indicating card variable color major cause inhomogeneous or that be shallower than reference colour is the water of condensation producing in steam sterilizing process, often the form with water droplet is gathered in metal or glass apparatus surface, and then soak sterilizing indication card colour-changing agent, cause sterilizing indication card variable color inhomogeneous or be shallower than reference colour.
The pressuresteam sterilization indicating card of domestic production at present does not have water-proof function.U.S. a company adopts solid state chemistry thing is encapsulated in to the method in metal sheeting, and when temperature rises, the liquid after solid state chemistry thing melts, along the printing and dyeing of refill passage, plays the object of waterproof, but has the shortcomings such as complex manufacturing technology, cost are higher.
summary of the invention
The object of the present invention is to provide a kind of waterproofing protection material, a kind of pressure steam sterilizing chemical tracer card with water-proof function is provided simultaneously.
The present invention is by the following technical solutions:
A material, in weight part, its composition is: acrylic resin 10-40 part, organic solvent 40-60 part, auxiliary rheological agents 1-10 part, pimelinketone 0-20 part and N-BUTYL ACETATE 0-20 part.
Described acrylic resin is B66 or BM66-D.
Described organic solvent is benzene class.
Described organic solvent is dimethylbenzene.
Described auxiliary rheological agents is gas-phase silica, dispersion agent HX-4800 or auxiliary rheological agents HX-8900.
When prepared by waterproofing protection material, get in proportion each raw material; first organic solvent, pimelinketone, N-BUTYL ACETATE are mixed; be stirred into solvent; then acrylic resin is added in solvent; being stirred to acrylic resin dissolves; under agitation add again auxiliary rheological agents to decomposing evenly, become the colloidal liquid of homogeneous transparent, be waterproofing protection material.
A pressure steam sterilizing chemical tracer card that adopts waterproofing protection material to make, pressure steam sterilizing chemical tracer card colour-changing agent surface uniform is coated with one deck waterproofing protection material.
The thickness of waterproofing protection material is 0.2-0.4mm.
During preparation, waterproofing protection material web is printed on to the waterproofing protection film of usual pressure steam sterilizing indicating card colour-changing agent surface, dry rear waterproofing protection material formation one deck uniform thickness (0.2-0.4mm), makes the pressure steam sterilizing chemical tracer card with water-proof function.
In the waterproofing protection film of pressure steam sterilizing chemical tracer card of the present invention, acrylic resin has the thermal softening of being subject to, and cooled and solidified and water-fast feature, mainly play waterproof action; Organic solvent is for high-efficiency dissolution acrylic resin; According to the difference of seasonal temperature, suitably add pimelinketone or N-BUTYL ACETATE, general in the situation that envrionment temperature is high (about more than 30 ℃) suitably add pimelinketone and delay to extend dried coating film, in the situation that envrionment temperature is low, (about below 20 ℃) suitably adds vinyl acetic monomer and accelerates dried coating film; Auxiliary rheological agents has the effects such as thickening, anti-precipitation, can make coating even simultaneously, prevents resin settled layering, and the bonding strength between raising coating and base material and hardness, transparency and the resistance to deterioration of coating, also make film be easy to open, and can not bond.
The present invention is printed in pressure steam sterilizing chemical discoloration indication agent surface by waterproofing protection material web and forms one deck waterproofing protection film; keeping the thickness of waterproofing protection film is 0.2-0.4mm; make like this pressure steam sterilizing chemical tracer card with water-proof function, this indicating card had not only had water-proof function and but also had not affected the normal variable color of pressuresteam sterilization indicating card.When producing pressuresteam sterilization indicating card; transparent watertight protective membrane of the present invention is spread upon to the surface of sterilizing indication card colour-changing agent; this transparent watertight protective membrane has the thermal softening of being subject to, cooled and solidified and water-fast feature, thereby solved water of condensation, soaks pressuresteam sterilization indicating card colour-changing agent and causes variable color inhomogeneous or be shallower than the problem of reference colour.Meanwhile, waterproofing protection film has effectively completely cut off contacting between indicating card colour-changing agent and air, and anti-oxidation, has played the effect that extends waterproofing protection film quality guaranteed period.
Along with the development of national medical and health care system, the demand of pressuresteam sterilization indicating card also will progressively rise.Develop waterproof type sterilizing indication card of the present invention and can reduce medical treatment cost, will have broad application prospects and certain social value.
