Problems solved by technology

[0003] The first solution, high-temperature self-adhesive paper is mainly imported from France, which can only realize the lamination of self-adhesive paper with PE, PP, CPP and other films. The same is true for Tyvek. Due to the high price, this kind of material is generally used for high value. For demanding occasions, the application range is limited
[0004] The second solution, solvent-based hot-melt adhesive is suitable for paper-film, paper-coated paper, the cost is relatively low, and it is widely used at present, but it needs to release a large amount of toluene and solvent gasoline during the glue coating process, which is safe. There are relatively high hidden dangers, and there is also relatively large pollution to the atmospheric environment.

Abstract

The invention discloses water-based disposable medical packaging hot melt glue and a production process. The water-based hot melt glue is prepared by adopting water-based acrylate emulsion, vinyl-acryl emulsion, vinyl-acetate emulsion, amorphous polypropylene (APAO) emulsion, polyethylene wax emulsion and paraffin emulsion, adding an anion emulsifier and a non-ionic emulsifier as stabilizers, andadding methyl silicone oil, vinyl silicone oil and the like by virtue of a compounding process. The hot melt glue is suitable for paper-film, paper-coated paper, and paper-paper packaging products, and can avoid the limitation and complexity of the existing hot melt glue preparation field.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a water-based disposable medical packaging hot melt adhesive and a production process. Background technique [0002] In the production of disposable medical sterilization packaging, there are currently three types of solutions: 1. Tyvek or high-temperature sterilization paper. 2. Solvent-based hot melt adhesive bonding. 3. Water-based hot melt adhesive bonding. [0003] The first solution, high-temperature self-adhesive paper is mainly imported from France, which can only realize the lamination of self-adhesive paper with PE, PP, CPP and other films. The same is true for Tyvek. Due to the high price, this kind of material is generally used for high value. In high demanding occasions, the scope of application is limited. [0004] The second solution, solvent-based hot-melt adhesive is suitable for paper-film, paper-coated paper, the cost is relatively low, and it is widely use...
