Abstract

The invention provides a light-shielding type medical PVC (Polyvinyl Chloride) infusion tube composition and a preparation method of the light-shielding type medical PVC infusion tube composition and belongs to the technical field of PVC infusion tube compositions. The light-shielding type medical PVC infusion tube composition is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin, 1.0 to 3.0 parts of a thermal stabilizer, 40 to 60 parts of a plasticizer, 1.5 to 4 parts of a compound light stabilizer, 0.01 to 0.025 part of titanium dioxide and 0.1 to 0.2 part of a lubricant; the compound light stabilizer is prepared by mixing a hindered amine light stabilizer, phenyl salicytate, benzotriazoles and 4-(1-naphthylazo)-1-naphthol. The light-shielding type medical PVC infusion tube composition provided by the invention has the advantages of less light capable of penetrating through a waveband of 290nm to 450nm, high transparency and no toxin.

Description

technical field [0001] The invention belongs to the technical field of PVC transfusion tube composition, and in particular relates to a light-shielding medical PVC transfusion tube composition and a preparation method thereof. Background technique [0002] In the clinical infusion process, some drugs (such as the anti-tuberculosis drug PAS) are easy to decompose when exposed to light, resulting in a decrease in curative effect, so they need to be infused in a light-proof environment. When light drugs are infused, dark plastic containers are often temporarily used to wrap the infusion bottle and the infusion tube. However, there are still many shortcomings and deficiencies in this operation method, which is not conducive to observing the liquid level and is inconvenient to operate. The wavelength range of the light that is likely to cause drug decomposition is 290-450nm. The national standard requires that the light-proof infusion tube has a transmittance of 290-450nm band li...
