Abstract

The invention provides a fruit fresh-keeping coating for a corrugated paper box and a preparation method of the fruit fresh-keeping coating. The preparation method comprises the following steps: (1) adding starch into water with 4 times of weight parts, placing the starch in a water bath pot, carrying out heating and stirring, and keeping the temperature until the starch is fully gelatinized for later use; (2) dissolving potassium permanganate in water with 200 times of weight parts to prepare a potassium permanganate solution for later use; (3) grinding wollastonite and volcanic rock, addingthe wollastonite and volcanic rock powder into the potassium permanganate solution together with powdery active carbon, and oscillating the mixture to enable the wollastonite, the volcanic rock and the powdery active carbon to fully absorb potassium permanganate; and (4) adding carboxyl styrene-butadiene latex, potassium permanganate solution, sodium polyphosphate, diallyl thiosulfinate, geraniol,thymol, fructose 1,6-diphosphate and the remaining water into the prepared starch solution according to a set proportion, and dispersing the mixture uniformly by a high-speed dispersion homogenizer to prepare a coating. The fruit fresh-keeping coating for the corrugated paper box, provided by the invention, has a good fresh-keeping effect, and meanwhile, the coating also has good antibacterial activity.

Description

technical field [0001] The invention relates to the field of fresh-keeping materials, in particular to a fruit fresh-keeping coating for corrugated boxes and a preparation method thereof. Background technique [0002] At present, corrugated cardboard has become one of the most widely used packaging materials in modern packaging. The data show that paper packaging products rank first among the various categories of products in the packaging industry, occupying a large proportion. In my country, its output value accounts for nearly 40% of the total output value of the packaging industry; in economically developed countries, it accounts for more than 45%. Corrugated box products account for more than 60% of the total output value of paper packaging products. Under such conditions, fresh-keeping corrugated boxes have broad development space and market potential. Since this box can be easily manufactured into a uniform specification, the storage space can be utilized to the gr...
