Organic glass material for medical glass bottles, and preparation method thereof

Abstract

The invention discloses an organic glass material for medical glass bottles. The organic glass material is prepared by a free radical polymerization from the following raw materials, by weight, 5-7 parts of methyl methacrylate, 1-3 parts of bis(trimethylsilyl)vinylphosphonate, 2-4 parts of vinyl ethylene carbonate, 1-2 parts of zinc 2-vinylbenzenesulfonate, 0.2-0.5 part of surface-modified glass fiber powder, 0.1-0.3 part of vinyl modified nano-silica, 0.05-0.1 part of an emulsifier and 0.05-0.1 part of a photoinitiator. A preparation method of the organic glass material for the medical glassbottles comprises the following steps: mixing the raw materials in proportion, performing ultrasonic treatment for 15-30 min, adding the obtained mixture into a mold, and irradiating the mixture withultraviolet rays having a wavelength of 180-220 nm in a nitrogen atmosphere for 40-50 min to obtain the organic glass material for medical glass bottles. The organic glass material for medical glass bottles has the advantages of high strength, non-fragility, smoothness and transparency, easiness in disinfection, excellent corrosion resistant, excellent resistance to a high temperature, and excellent sealing performance, and meets the requirements for materials for medical glass bottles.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a material for medical glass bottles, more specifically, to an organic glass material for medical glass bottles and a preparation method thereof. Background technique [0002] With the rapid development of the medical and health industry and people's demand for improving the quality of medical services, medical glass bottles have gradually become the main packaging containers for medical products such as medicines. It has packaging characteristics that cannot be replaced by other packaging containers. People's requirements for it are gradually increasing. In addition to packaging and sealing performance, it is also required to be clean and transparent, easy to sterilize, corrosion-resistant, and high-temperature resistant. [0003] At present, the production process of medical glass bottles in the prior art mainly includes: raw material preprocessing, preparation of batch...

AI Technical Summary

Problems solved by technology

However, this process is complex, difficult to operate, and requires high equipment

The prepared medical glass bottles are relatively thin. When in use, if they are accidentally impacted or dropped, they are easy to break, and they do not have the effect of sterilization. These defects limit their wide application in the pharmaceutical industry

[0004] Chinese Patent Publication No. CN 107586019A discloses a medical glass bottle formula and its preparation method, including the following components in parts by weight: 40-50% of quartz sand, 15-20% of soda ash, 5-10% of limestone, 1% of sodium nitrate -5%, borax 1-5%, nano-silver ion powder 1-5%, nickel oxide 0.001-0.005%, and the rest is broken glass with borax. The medical glass bottle prepared by the invention has uniform wall thickness, strength and thermal stability Excellent, and has antibacterial and bactericidal properties, but its component raw materials are expensive, the molding process is complicated, and it does not effectively solve the problem of traditional glass bottles being fragile
