Embodiment Construction

[0024] In terms of parts by weight, weigh 3 to 5 parts of peony petals, 1.5 to 1.8 parts of pomegranate leaves and 2 to 4 parts of tartary buckwheat stems and leaves and mix them evenly in a beaker to obtain a mixed product. Place the beaker at a temperature of 70 to 80°C Dry in an oven for 15 to 16 hours, and weigh 3 to 5 parts of cellulase, 1 to 2 parts of pectinase and 35 to 38 parts of ethanol solution with a mass fraction of 60 to 70% by weight to prepare a mixed Enzyme liquid: Pour the above mixed enzyme liquid into the above beaker to impregnate the above dried mixed product, place the beaker in an ultrasonic oscillator, and vibrate at a constant temperature under the conditions of an ultrasonic frequency of 40-45kHz and a temperature of 45-50°C 100-120min, shake and filter to obtain the filtrate, put the filtrate into a three-necked flask, raise the temperature to 90-100°C to condense and reflux, condense and reflux until the substance in the three-necked flask has a co...

Abstract

The invention relates to a preparation method of a waterproof antibacterial kraft paper packaging material, and belongs to the technical field of kraft paper bag preparation. A reaction emulsion is prepared by using peony petals, pomegranate leaves and tartary buckwheat stems and leaves as raw materials, shrimp shell and crab shell are ground and mixed to obtain a reaction product, and finally thereaction product, the reaction emulsion, a wood pulp material and other auxiliary agents are mixed and put into a paper making machine to produce the waterproof antibacterial kraft paper packaging material; flavonoids have good antibacterial activity, can also block the metabolism of cells, avoids mold and deterioration of the kraft paper packaging material, and can be well pasted with the wood pulp material. Chitin and chitosan are extracted from the shrimp shell and crab shell as raw materials. The chitosan has the bactericidal and antibacterial effect, and can also make kraft paper is noteasy to wet and tear, and the waterproof antibacterial kraft paper packaging material has broad application prospects.

Description

technical field [0001] The invention relates to a preparation method of a waterproof and antibacterial kraft paper packaging material, belonging to the technical field of kraft paper bag preparation. Background technique [0002] Packaging materials are widely used in packaging containers, packaging decoration, packaging printing, packaging and transportation, etc., which play an important role in industrial production and people's daily life. With the continuous development of my country's industrialization, the types and production of industrial products are increasing year by year, and the annual consumption of packaging materials is also increasing. Therefore, the demand for packaging materials in our society has risen sharply. According to statistics, 80% of the used plastic bags in our country are finally transported to the landfill area for disposal like general garbage, and only 7% of the plastic is recycled and recycled, so paper packaging bags are needed. [0003]...
