Abstract

The invention discloses a method for preparing a tear-resistant paper plate. The method comprises the following steps: fragmenting the poplar bark, then beating the poplar bark, adding hyaluronic acid, quartz sand, etherified starch, and sodium hydrogen sulfate and uniformly mixing the materials to obtain a slurry; adding water in the slurry, performing sand removal and sieve treatment in order,and then adding modified toughened xanthan gum, silica gel, glacial acetic acid, and acrylic resin, stirring the materials, adding wollastonite powder, diatomite, medical stone powder, and coal gangueand continuously stirring the materials to obtain a premix; dehydrating the premix, and moulding and drying the material to obtain the tear-resistant paper plate. The modified toughened xanthan gum is prepared by the following steps: adding water to the xanthan gum, heating the material, adding a sodium hydroxide solution and stirring the material, adjusting the system to neutrality, adding anhydrous ethanol, under nitrogen, heating the material and stirring the material evenly, adding styrene and mixing the material evenly, adding dicumyl peroxide, and performing steps of stirring, filtering, washing, and drying to obtain the modified toughened xanthan gum.

Description

technical field [0001] The invention relates to the technical field of paper trays, in particular to a preparation method of a tear-resistant paper tray. Background technique [0002] With the rapid development of the household paper industry and the increasing demand of consumers for high-end household paper trays, ordinary household paper trays can no longer meet the needs of consumers, so various functional household paper trays Products have also appeared on the market, one of which is a product with stretch and tear resistance. At present, the stretch resistance and tear resistance are generally achieved by increasing the quality of the paper tray, which not only increases the cost, but also is inconvenient to use, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a tear-resistant paper tray, which has a simple process and i...
