Abstract

The invention discloses a preparation method of a waterproof stain-resistant wood packaging box material, which comprises the following steps: steaming a wood material at high temperature, cooling toroom temperature, vacuumizing, maintaining the pressure, and recovering to normal pressure to obtain a pretreated wood material; the preparation method comprises the following steps: mixing epoxy silane, ethyl methacrylate, methacrylic acid, acrylamide, glycidyl acrylate, diethylenetriamine and adipic acid, adding nano silicon dioxide and a surfactant in a stirring state, and continuously stirringto obtain an initial solution; toluene diisocynate, ammonium fluorocarboxylate, a surfactant and water are mixed, the pretreated wood material is immersed in the mixture, the initial solution, epichlorohydrin and peroxide are slowly dropwise added in sequence in a stirring state, and ultrasonic oscillation is performed to obtain an impregnated wood material; and the impregnated wood material is naturally cooled to normal temperature, pressurizing and maintaining pressure are carried out, then the material is cooled to normal pressure, the surface impregnation liquid is drained, and dried to constant weight, and heat treatment is carried out to obtain the waterproof stain-resistant wood packaging box material.

Description

technical field [0001] The invention relates to the technical field of wooden packing box materials, in particular to a waterproof and stain-resistant wooden packing box material and a preparation method thereof. Background technique [0002] Packaging is the overall name of containers, materials and auxiliary materials used in the process of circulation to protect products, facilitate storage and transportation, promote sales, and use certain technical methods. Packaging not only has the function of wrapping boxes, but also can modify items to win the favor of the audience. With the continuous development of the modern logistics industry, people pay more attention to the safety and quality of the items when transporting items, so different items will be transported and stored in different packages during the transportation process. [0003] As a commonly used transportation packaging container, wooden packaging boxes are convenient to obtain materials, easy to make, light ...
