Embodiment Construction

[0022] Soak 300-350 g of corn kernels in 400-500 mL of sulfurous acid solution with a mass fraction of 0.8% for 6-8 hours, take out the soaked corn kernels, and crush the corn kernels in a disc crusher for 1-2 hours to obtain corn Paste, pass corn paste through a centrifugal sieve with a sieve hole diameter of 0.06-0.08mm to obtain sieved corn paste, sieve corn paste, lime water with a mass fraction of 2% and polyacrylamide in a mass ratio of 2:7:1 Mix and disperse in a high-speed disperser at a speed of 3000-3500r / min for 10-15 minutes to obtain modified starch material; add 800-900mL of sodium hydroxide solution with a mass fraction of 25% and 300-400g of soybean protein to a three-necked flask , heat up to 70-80°C, start the agitator, and keep stirring at a speed of 150-200r / min for 1.5-2.0 hours to obtain the reaction solution. After the reaction solution is cooled to room temperature, add hydrochloric acid to adjust the pH of the reaction solution to 6.5 ~7.0, to obtain a...

Abstract

The invention discloses a preparation method of an air-blocking and anti-tension infusion bag material, and belongs to the technical field of preparation of medical materials. The preparation method is characterized in that the macromolecular polymer raw material is filled with asphalt, so that the tension elasticity of an infusion bag is enhanced, and the heat-resistant property and anti-tensionproperty of the infusion bag are improved by doping butadiene-acrylonitrile rubber powder and asphalt due to larger temperature sensitivity of the asphalt; the soybean protein is modified by alkalineunder the condition of higher concentration of sodium hydroxide solution, so that the density of the infusion bag in curing is improved, the larger cohesion is provided when the infusion bag is tensioned, the micromolecular peptide chain which is thermally degraded with the soybean protein can be dewatered and combined to form the viscous surface active matter, and the absorbing of water steam byan opening of the infusion bag is reduced; because the starch particle is firmly fixed in a substrate under the curing function of lime water(calcium hydroxide)after drying, the calcium hydroxide is dried and cured to produce the calcium oxide, and the calcium oxide can react with carbon dioxide and water in air again, so that the air blocking and water absorbing functions are realized; the application prospect is broad.

Description

technical field [0001] The invention discloses a method for preparing a gas-blocking and stretch-resistant transfusion bag material, which belongs to the technical field of medical material preparation. Background technique [0002] New medical materials refer to a class of materials with special properties and special functions, which are used for artificial organs, surgical repair, physiotherapy rehabilitation, diagnosis and treatment of diseases, and do not have adverse effects on human tissues. Among them, the most widely used category is medical polymer materials, specifically referring to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices. Its sources include natural biopolymer materials and synthetic biopolymer materials. Natural medical polymer materials come from nature, including cellulose, chitin, hyaluronic acid, collagen, gelatin and sodium alginate, etc.; synthetic medical polymer mater...
