Abstract
The invention discloses a TPE material for a titrimeter of an infusion device and a preparation method thereof. The TPE material comprises the following raw materials by weight: 60-80 parts of ethylene-octene segmented copolymer, 20-40 parts polypropylene, 1-1.5 parts of stearamide, 0.4-0.8 part of an antioxidant, 10 parts of white oil, wherein the total weight is 100 parts and the ethylene-octene segmented copolymer is an OBC elastomer. Compared with commonly used PVC material for the titrimeter of the infusion device, the TPE material provided by the invention has the following advantages: (1) the TPE material does not contain vinyl chloride monomer or a plasticizer DEHP, and protects the health of patients and medical workers; (2) the TPE material has no absorption on the drug, and does not affect the therapeutic effect; (3) the TPE material does not apply to additive of metal ions, so as to prevent the patients from the harm of metal ions; and (4) the TPE material does not produce carcinogenic dioxin gas in burning.
Description
Technical field
The present invention relates to a kind of TPE material for infusion unit titrimeter and preparation method thereof.
Background technology
Nowadays, what most of infusion unit titrimeter still adopted is PVC material, although this material has the advantages such as cheap, mechanics good mechanical performance, production technique are simple, but minute quantity vinyl chloride monomer residual in material and add the softening agent DEHP that must add man-hour and all can produce larger harm to human body, absorption is had to medicine, affect the treatment, carcinogenic dioxin gas during burning, can be produced.
Summary of the invention
Object of the present invention, provides a kind of TPE material for infusion unit titrimeter and preparation method thereof exactly in order to solve the problem.
The object of the present invention is achieved like this:
A kind of TPE material for infusion unit titrimeter of the present invention, comprises the raw material by following weight proportion:
Wherein, described ethylene-octene segmented copolymer is OBC elastomerics.
Above-mentioned a kind of TPE material for infusion unit titrimeter, wherein, described oxidation inhibitor is that antioxidant 1010 and irgasfos 168 are composite by equal proportion.
Present invention also offers a kind of preparation method of the TPE material for infusion unit titrimeter.Comprise the following steps:
(1) take raw material by weight ratio: ethylene-octene segmented copolymer 60-80 part, Co-polypropylene 20-40 part, stearylamide 1-1.5 part, oxidation inhibitor 0.4-0.8 part, white oil 10 parts, and total amount is 100 parts;
(2) put into high-speed mixer and mixing evenly with ethylene-octene segmented copolymer after stearylamide and oxidation inhibitor white oil being dissolved, then add Co-polypropylene, mix discharging after 3-5 minute;
(3) raw material of mixing is put into screw machine extruding pelletization, the rotating speed of screw machine is 30-50 rev/min, and temperature is 170-190 DEG C.
Compared with the PVC material that TPE material of the present invention is conventional with infusion unit titrimeter, have the following advantages: (1) is vinyl-chloride-containing monomer and softening agent DEHP not, the health of protection patient and medical personnel; (2) to medicine without absorption, do not affect the treatment; (3) inapplicable metal ion is as additive, prevents metal ion from working the mischief to patient; (4) burning does not produce the carcinogenic dioxin gas of energy.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1-3
The raw material of corresponding weight proportion is taken by table 1, after first stearylamide and oxidation inhibitor being dissolved with white oil, high-speed mixer and mixing is put into again even together with ethylene-octene segmented copolymer, then Co-polypropylene is added, mix discharging after 3-5 minute, the raw material of mixing is put into screw machine extruding pelletization, and the rotating speed of screw machine is 30-50 rev/min, and temperature is 170-190 DEG C.The TPE material of the present invention for infusion unit titrimeter can be obtained.
Table 1: each raw material weight proportioning in embodiment 1-3
Carried out performance test respectively to the TPE material that embodiment 1-3 obtains, test result is as shown in table 2:
Table 2: the performance test results of embodiment 1-3 gained TPE material
From above-mentioned test result, TPE material provided by the invention, by regulating the ratio of OBC elastomerics and Co-polypropylene, the object regulating hardness can be reached, and stable chemical performance, and can be used for directly being injection molded into multiple TPE product, be the PP Pipe Compound can producing single use TPE infusion unit titrimeter in cleaning shop in enormous quantities.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
Claims (3)
