Embodiment 1

[0027] First choose 40 parts by weight of vinyl chloride, 20 parts by weight of vinyl acetate, 20 parts by weight of acrylic ester monomers, 0.8 parts by weight of initiator, 2 parts by weight of dispersant and 150 parts by weight of deionized water, stand-by . Wherein, the acrylate monomer is ethyl acrylate; the initiator is di(2-ethyl)hexyl peroxydicarbonate; the dispersant is a grafted polyvinylpyrrolidone and methyl cellulose copolymer.

[0028] Then, add ion-free water and dispersant into the reactor, and stir evenly to fully dissolve the dispersant.

[0029] After that, 1 / 6 of the acrylate monomer and vinyl acetate were added and stirring was continued for 10 minutes.

[0030] Afterwards, the initiator and 1 / 3 of the vinyl chloride were added and stirring was continued for 28 minutes.

[0031] Afterwards, the reactor is heated so that the material temperature in the reactor rises to 35 degrees Celsius, and the reaction is carried out at this temperature, so that the p...

Embodiment 2

[0039] First choose 50 parts by weight of vinyl chloride, 28 parts by weight of vinyl acetate, 30 parts by weight of acrylate monomer, 2 parts by weight of initiator, 3.5 parts by weight of dispersant and 180 parts by weight of deionized water, stand-by . Wherein, the acrylate monomer is butyl acrylate; the initiator is di(2-ethyl)hexyl peroxydicarbonate; the dispersant is a grafted polyvinylpyrrolidone and methyl cellulose copolymer.

[0040] Then, add ion-free water and dispersant into the reactor, and stir evenly to fully dissolve the dispersant.

[0041] After that, 1 / 4 of the acrylate monomer and vinyl acetate were added and stirring was continued for 15 minutes.

[0042] Afterwards, the initiator and 5 / 12 vinyl chloride were added and stirring was continued for 30 minutes.

[0043] Afterwards, the reactor is heated, so that the material temperature in the reactor rises to 43 degrees Celsius, and the reaction is carried out at this temperature, so that the pressure in ...

Embodiment 3

[0051] First choose 60 parts by weight of vinyl chloride, 35 parts by weight of vinyl acetate, 40 parts by weight of acrylic ester monomers, 3 parts by weight of initiators, 5 parts by weight of dispersants and 200 parts by weight of deionized water, stand-by . Wherein, the acrylate monomer is mixed according to the weight ratio of butyl acrylate: methyl methacrylate = 1:2, and the acrylate monomer can also be mixed according to the weight ratio of ethyl acrylate: methyl methacrylate ester = 1:1 by weight ratio, and in this embodiment, the acrylate monomers are mixed by weight ratio of butyl acrylate: methyl methacrylate = 1:2. The initiator is di(2-ethyl)hexyl peroxydicarbonate; the dispersant is a graft copolymer of polyvinylpyrrolidone and methylcellulose.

[0052] Then, add ion-free water and dispersant into the reactor, and stir evenly to fully dissolve the dispersant.

[0053] After that, 1 / 3 of the acrylate monomer and vinyl acetate were added and stirring was continu...

Abstract

The invention discloses resin for a blood transfusion tube / transfusion bag and a preparation method thereof, and in particular relates to special resin for producing medical blood transfusion tubes and transfusion bags and the preparation method thereof. The resin is characterized in that the resin for the blood transfusion tube / transfusion bag is prepared by mixing, stirring, reacting, washing, dehydrating, re-washing, re-dehydrating, drying and sieving materials such as chloroethylene, vinyl acetate, acrylate monomers, an initiator, a dispersant and deionized water. With the adoption of the resin for production of the blood transfusion tube / transfusion bag, performance and service life of the blood transfusion tube / transfusion bag can be improved to the benefit of personal health.

Description

technical field [0001] The invention relates to a resin and a preparation method thereof. Specifically, it is a special resin for producing medical transfusion vessels and transfusion bags and a preparation method thereof. Background technique [0002] At present, in the field of blood transfusion and infusion bag production, most of the special resins for the production of medical blood transfusion and infusion bags are SG-5 polyvinyl chloride or SG-4 polyvinyl chloride. In order to meet the flexibility requirements of blood transfusion and infusion bags, The amount of plasticizer is increased, and its mass is as high as 45%. Among them, commonly used plasticizers are dioctyl phthalate or dibutyl phthalate. Because plasticizers will migrate in blood transfusion vessels and infusion bags, it will reduce the performance and lifespan of blood transfusion vessels and infusion bags, and endanger human health. Contents of the invention [0003] The problem to be solved by th...
