Abstract

The invention belongs to the plastic working Application Areas, disclose a kind of prescription of medical PVC, this prescription has adopted the synergism complementarity effect of multiple stablizer, has importantly used organotin stabilizer, has obtained tangible positively effect.Production cost is low, and raw material is easy to get, good product quality, particularly biological chemical performance excellence, and transparency and color and luster are good, are suitable for applying both at home and abroad, can be used for medical apparatus or food product pack etc.

Description

The present invention is a kind of prescription of medical PVC, and this formulation material is mainly used in medical apparatus, also can be used for other containers for medical use and food product pack, belongs to plastics processing and application technology.

Because polyvinyl chloride resin has the good biological safety and the transparency, cheap, so be widely used in the production of various medical apparatus, most widely used general on disposable medical appliances such as disposable blood transfusion and infusion device and bags of blood especially.

Yet the existing disadvantage of polyvinyl chloride resin is to be heated easily to decompose, and in molding process, is heated and can emits HCL, makes performance become bad.So polyvinyl chloride resin all adds an amount of thermo-stabilizer in use.

Most widely used general also effective stabilizer is the organism of lead, barium, cadmium in polyvinyl chloride resin, but these heavy metal compounds all are deleterious, and they are harmful, are not suitable for using in medical article.

At present, employed stablizer all is that Ca/Zn type stablizer and epoxy soybean oil are used in the medical PVC prescription, and the representative formula of flexible PVC is as follows:

100 parts of PVC

30~80 parts of DOP

0.01~5 part of Ca/Zn stablizer

0~10 part of epoxy soybean oil

0~5 part of lubricant

By the prepared PP Pipe Compound of above prescription, its thermostability and irradiation stability are relatively poor, and appearance color has yellow when making goods, and the transparency is also relatively poor.

Improvement technology to above conventional formulation was once arranged, as European patent EP-0,165 in 1985, No. 579 applications and Romanian patent RO-88, No. 824 applications.The former has added unsaturated fatty acids diacid dialkyl ester (R on the basis of conventional formulation 1OCOCR 3=CR 4COOR 2) 0.1~50 part, the latter has added barium sulfate.

Above-mentioned two inventions have improved the radiation hardness stability preferably.But the thermostability and the transparency of the goods that all prescriptions of prior art are produced are all undesirable.

The objective of the invention is existing prescription is improved, on the basis that does not influence medical function, improve the thermostability of mixing material and the transparency and the color and luster of goods.

Above-mentioned purpose realizes by following design: well-known, organotin can make the PVC stabilization and help keeping original color and luster, but its lubrication is poor, must be aided with other stablizer and lubricant.So this medical PVC compound disclosed in this invention contains plasticizer DOP, stablizer (Ca/Zn), epoxy soybean oil and lubricant etc., unusual part of the present invention just is to have added organotin, this class organotin must be thioalcohol type or bay acid type, its add-on is 0.01~5 part, optimum content is 0.05~0.3 part, and concrete prescription is:

100 parts of PVC

0~80 part of DOP

0.01~5 part of Ca/Zn stablizer

0~10 part of epoxy soybean oil

0~5 part of lubricant

0.01~5 part of organotin stabilizer

The medical PVC PP Pipe Compound, not only requiring has good physical and mechanical properties, the more important thing is that the biological chemical performance of medical field requirement is relatively stricter.And the product appearance of producing with PP Pipe Compound requires smoothly, transparent, colourless, and this is that health care is desired.

The present invention be directed to the existing in prior technology problem, with the sanitary grade PVC is raw material, with health level DOP is softening agent, its key problem in technology is to adopt performance complement, three kinds of stablizers with synergy are used, make every well behaved medical PVC PP Pipe Compound with appropriate proportioning and processing method, three kinds of stablizers that adopted are Ca/Zn one package stabilizer, organotin stabilizer and epoxy soybean oil.

System is with addition of worker's technology:

(1) technological process such as Fig. 1

(2) processing condition:

Mix with GH-10 type high-speed mixer:

Rotating speed is that 1250 rev/mins of mixing times are 5~7 minutes

With PLD-651 type extrusion molding instrument extruding pelletization:

Extrusion temperature is 175 ℃

The inventive method has obtained very significantly positively effect through verification experimental verification.And following advantage is arranged, and low as cost, raw material is easy to get, good product quality, and the biological chemical performance excellence, especially visual appearance is good, clear, colorless, its modified effect is seen attached list, and remarkable in economical benefits, and this technology is suitable for applying both at home and abroad.

Below be two formulation examples:

Example 1:

Use homogenizer with PVC, DOP, Ca/Zn one package stabilizer, dimercapto 2-ethyl hexyl ethanoate dioctyltin, epoxy soybean oil with 100: 55: 1.5: 0.2: 5 ratio height is mixed and is closed 5~7 minutes, and extruding pelletization makes the medical PVC PP Pipe Compound under 175 ℃ condition.

Example 2:

Use homogenizer with PVC, DOP, Ca/Zn one package stabilizer, Bis(lauroyloxy)dioctyltin, epoxy soybean oil with 100: 55: 1.5: 0.2: 5 ratio height is mixed and is closed 5~7 minutes, and extruding pelletization makes the medical PVC PP Pipe Compound under 175 ℃ condition.

Its performance is seen attached list.

Conventional formulation Example 1. Example 2. PVC DOP Ca/Zn stablizer epoxy soybean oil dimercapto 2-ethyl hexyl ethanoate dioctyltin Bis(lauroyloxy)dioctyltin 100 55 2 5 - - 100 55 1.5 5 0.2 - 100 55 1.5 5 - 0.2 * heat-stable time (hr) transparent color and luster 3 is yellowish little turbid 5.5 water white transparency 5.4 water white transparency

* annotate: according to the ASTM standard: congo red method is surveyed the stability of PVC.
