Abstract
The invention discloses a kind of combined material for Anesthesia machine, the combined material includes the component of following mass percent：Makrolon 55%-60%, polybutylene terephthalate (PBT) 20%-25% and glass fibre 20%-25%.Not only resistance to anaesthetic corroded combined material of the invention but also shaping is easy, and cheap intensity is high.
Description
Technical field
The invention belongs to Anesthesia machine manufacturing technology field, in particular it relates to a kind of combination for Anesthesia machine
Material.
Background technology
Top board, workbench, drawer are Anesthesia machine important components, the general LOGO with manufacturer on top board
And machine models, sometimes user can place patient monitor or medicine etc., workbench is generally used for medical personnel and writes or face
When place operating theater instruments and medicine etc., drawer can often fill some day conventional anaesthesia pipeline, gas path module or other things
Product.
Top board, workbench, drawer of Anesthesia machine in the market etc. are general by PC/ABS materials or PBT plastic
It is made, PC/ABS is makrolon and acrylonitrile-butadiene-styrene (ABS) alloy, it uses universal and be easily worked
Characteristic also makes its price extremely cheap, and it has the disadvantage the corrosion intolerant to anaesthetic, if medical worker's work is careless,
Anesthetic liquid medicine is poured into work top etc., work top can be corroded, form pit.The resistance to arcotic of PBT plastic
Thing corrodes, but expensive, X/Y opposite sex during shaping, easily produces product buckling deformation to be difficult to control.
The content of the invention
It is an object of the present invention to provide a kind of combined material for Anesthesia machine, the combined material both resistance to arcotic
It is easy that thing corrosion is molded again, and cheap intensity is high.
To reach above-mentioned purpose, present invention employs following technical scheme：
A kind of combined material for Anesthesia machine, the combined material includes the component of following mass percent：Poly- carbon
Acid esters 55-60%, polybutylene terephthalate (PBT) 20-25% and glass fibre 20-25%.
An optimal technical scheme of the invention, the combined material includes the component of following mass percent：
Makrolon 55%, polybutylene terephthalate (PBT) 25% and glass fibre 20%.
Present invention also offers the preparation method of combinations thereof material, according to above-mentioned constituent mass percentage, weigh
Each component is blended, and type is moulded using injection, extrusion molding or drawing after blending.
PC is the abbreviation of makrolon, and the English of makrolon is Polycarbonate, abbreviation PC engineering plastics,
It is the one kind in engineering plastics, PC is a kind of armorphous thermoplastic resin of high comprehensive performance, with excellent electricity
Insulating properties, extensibility, dimensional stability and chemical resistance, intensity higher, heat resistance and cold resistance；Also
There is self-extinguishment, fire-retardant, nontoxic, pigmentable, PC plastics can be seen in each corner of life, big rule
Mould industrial production and the characteristic being easily worked also make its price extremely cheap, and injection moulding is easy, but it is intolerant to anesthesia
Medicine corrodes.
PBT plastic refers to polybutylene terephthalate (PBT) (Polybutylene terephthalate), also known as poly- to benzene
The methine ester of dioctyl phthalate four, abbreviation PBT.It is the condensation polymer of terephthalic acid (TPA) and 1,4- butanediols.PBT and PET
The crystallinity engineering plastics that thermoplastic polyester is a kind of function admirable are collectively known as, rigidity and hardness are high, thermally-stabilised
Property is good.Density is 1.30~1.38g/cm3, crystalline melt point is 220~267 DEG C；It has excellent shock resistance,
Intensity is high, fatigue durability, because coefficient of friction is low, wearability is extremely excellent, and good stability of the dimension, creep is also small, moisture absorption
Property it is smaller, product can improve its impact strength 10~15% after being annealed through 120 DEG C, heat-proof aging, and chemically-resistant is rotten
Corrosion is good (in addition to concentrated nitric acid), also resistance to anaesthetic, and molding shrinkage is 1.7~2.2% (larger), due to its tool
Vertical and horizontal change in size ratio is different after having anisotropy, therefore injection moulding, forms precision product higher
It is relatively difficult.
(English original name is glass fibre：Glass fiber or fiberglass) it is a kind of inorganic non-metallic of excellent performance
Material, species is various, and advantage is that good insulating, heat resistance be strong, corrosion resistance is good, high mechanical strength, but shortcoming
It is that property is crisp, wearability is poor.It is with glass marble or discarded glass as raw material through high temperature melting, wire drawing, doff,
What the technique such as weave cotton cloth was manufactured into, a diameter of several microns of its monofilament to twenties microns, equivalent to a hair
The 1/20-1/5 of silk, is made up of per bundle fiber precursor hundreds of even thousands of monofilament.Glass fibre is typically used as
The national economy such as the reinforcing material in composite, electrically insulating material and heat-insulating material, circuit substrate each neck
Domain.Glass fibre as reinforced plastics supporting material application when, maximum is characterized in big tensile strength.Tension is strong
Degree is in normal conditions 6.3~6.9g/d, 5.4~5.8g/d of moisture state, density 2.54.It is heat-resist, temperature
Do not have influence on intensity during up to 300 DEG C.There is excellent electrical insulating property, be senior electrically insulating material, be also used for heat insulating material
Material and fire-proof shield material.It is general only to be corroded by concentrated base, hydrofluoric acid and SPA.
Combined material of the invention can be used to prepare on the Anesthesia machines such as the top board of Anesthesia machine, workbench, drawer may be with
The appearance part of anaesthetic contact.
Combined material of the invention overcome PC intolerant to anesthesia the property of medicine, make use of mechanicalness, the impact strength of PC
With the property such as heatproof, uvioresistant (UV), while also overcome the anisotropic shortcoming of PBT material, using it
The characteristics of resistance to anaesthetic, the addition of glass fibre further increases the intensity of material, and and these three material valencys
Lattice are cheap, and the machine-shaping that combines easily, is easy to obtain raw material from market.Meet outside Anesthesia machine well
See the not only resistance to anaesthetic corrosion of part but also shaping is easy, cheap production and application requirement.
