Problems solved by technology

Applied to hard blister, because the lignocellulose of dialysis paper is relatively brittle, it requires a lot of peeling strength, and if the amount of glue is large, the heat-sealed package is easy to produce paper wool and paper scraps during the opening process.

Abstract

The invention discloses a water-based coating heat-sealing adhesive, a coating process and application of the water-based coating heat-sealing adhesive in medical dialyzing paper, and relates to the field of medical instrument packaging materials. The water-based coating heat-sealing adhesive is prepared from the following raw material components in parts by weight: 40 to 60 parts of water, 16 to 25 parts of butyl acrylate, 15 to 23 parts of styrene, 1 to 3 parts of acrylic acid, 0.5 to 3 parts of (Z)-capsaicin, 0 to 4 parts of masticadielic acid, 0.5 to 2.5 parts of aodium dodecyl sulfate, 0.5 to 1.5 parts of alkylphenol polyoxyethylene and 0.15 to 0.6 part of ammonium persulfate. The water-based coating heat-sealing adhesive prepared by the invention has excellent water resistance and low content of volatile organic compounds, and is safe and environment-friendly; the high-temperature-resistant and low-temperature-resistant stability is good, and the storage period is relatively long; and after being used for a medical dialyzing paper coating, the coating has good cohesiveness and high material strength, and can be subjected to good heat sealing with other materials.

Description

technical field [0001] The invention belongs to the field of medical device packaging materials, and in particular relates to a water-based coating heat-sealing adhesive, a coating process and its application in medical dialysis paper. Background technique [0002] Conventional medical dialysis paper is made from dehydrated wood pulp, and its main body is wood cellulose. It is widely used as packaging material for medical sterilization bags and can be sterilized by ethylene oxide high temperature steam. Since the lignocellulose of dialysis paper cannot be heat-sealed with other polymer materials such as PETG, PVC, PS, PP, APET, PET, and PE, it is necessary to develop a coating heat-sealing adhesive that can be used for dialysis paper. It can be heat-sealed with other materials, and used as a hard blister sealing cover material for medical sterilized paper-plastic bags or third-class medical devices for packaging various medical materials such as syringes, catheters, tweezers...
