Manufacturing method for cold insulation cup structure

Abstract

Provided is a manufacturing method for a cold insulation cup structure. The method comprises: coating a protection layer on a cup body, coating water-absorbing resin on the protection layer, the water-absorbing resin being formed by mixing non-water soluble printing ink with polyacrylate, polyacrylamide, or vinyl acetate / maleic acid copolymer, dosage concentration of the polyacrylate, the polyacrylamide, or the vinyl acetate / maleic acid copolymer being 1-30%, and then coating a permeable layer on the water-absorbing resin, the permeable layer being a material mixed by polyethylene or polypropylene with nanometer or micrometer calcium carbonate or silicon dioxide. Thus, the protection layer can block the water-absorbing resin and the cup body, preventing the cup body from adhesion and fading. By using the water-absorbing resin, a coated position can form a cold insulation water-absorbing three-dimensional pattern region after the coated position absorbs water and expands, and through the permeable layer on the coated position, steam is eliminated, so as to achieve effects of sanitation in use, no decolored patterns, effective water adsorption and cold insulation, ice prevention and slip limitation, and easy holding. The method maintains the cup body to be beautiful, and the cup body can be printed.

Description

technical field [0001] The invention relates to a method for manufacturing a cold-keeping cup structure, especially to a water-absorbent resin printing method in which non-water-soluble ink is mixed with polyacrylate, polyacrylamide, or vinyl acetate / maleic acid copolymer On the structure of the cup body, it can form a cold and water-absorbing three-dimensional pattern area after the coating part absorbs water and expands, so as to achieve sanitation during use, the pattern will not fade, keep the cup body beautiful, effectively absorb water and keep cold, prevent ice and slip, and be easy to hold And a method of manufacturing a structure that combines the effects of printability. Background technique [0002] Cups are used to hold water or beverages for people to drink. Generally, the beverages contained in cups are mainly ice or hot.

Problems solved by technology

[0002] Cups are used to hold water or beverages for people to drink. Generally, the beverages contained in cups are mainly ice or hot. However, for cups containing ice-cold beverages, the outer edge of the cup will produce water drops due to condensation of air, causing users When holding the cup, the palm is wet and slippery, making it difficult to grasp the cup. If you are not careful, the cup will easily slip from your hand, and the water droplets generated on the outer layer of the cup will flow down the cup body to the bottom of the cup, making the tabletop Wet and form water stains, in addition to polluting the desktop, it is also easy to cause the cup to slip due to the residual water stains on the desktop, which will cause inconvenience in use

[0003] In view of the lack and troubles of the current cups when they are used, because when the cups are filled with ice-cold drinks, the body of the cup is prone to water droplets, which is easy to wet and slippery, difficult to grasp, and wet the table. Therefore, it generally cannot meet the needs of users in actual use. required
