Problems solved by technology

In the 1970s, a lot of research was done on the modification of melamine formaldehyde resin abroad, and melamine formaldehyde resin with high solid content and stable storage was developed. This kind of resin achieved satisfactory results in the coating formulation of starch latex mixed adhesive. However, even the modified melamine resin will still produce a large amount of formaldehyde gas, volatile solvents or cracked small molecules in the process of production, storage and use, which will cause serious harm to human health, cause flammability, pollute the air, and cause serious harm to human health. The surrounding environment is unfriendly and greatly limits the scope of its use, so it is gradually eliminated
However, the traditional wax treatment has the problems of low strength, easy wear and poor stability.
Moreover, the waxing process of traditional corrugated boxes only stays at the level of manual wax dipping technology, the production efficiency is low, and the quality is difficult to guarantee

Embodiment 1

[0024] Preparation of wax liquid: The wax liquid is prepared from the following raw materials in weight ratio: 30% microcrystalline paraffin wax, 10% oxidized polyethylene wax, 5.0% amide wax, 1.5% silica nano powder, 1.0% rosin, surface The active agent is 0.5%, and the balance is water. The oxidized polyethylene wax is an oxidized modification of high-pressure low-density polyethylene wax; the surfactant is sorbitan fatty acid ester; the amide wax is ethylene bisstearic acid amide; and the water is tap water. First add the above-mentioned microcrystalline paraffin, oxidized polyethylene wax, amide wax, surfactant and rosin into the container and heat to 100~110°C, then add water and nano-powder materials, and quickly heat up to 130°C, wait for the microcrystalline paraffin, After the oxidized polyethylene wax and amide wax are fully dissolved, keep the temperature at 85-90°C, stir at a speed of 600-700r / min, stir for 30-40min, and cool to room temperature.

Abstract

The invention discloses a production technology of a waterproof wax-impregnated corrugated paper box. The production technology comprises six steps of putting a paper box on a hanging frame, pre-heating in a pre-heating drying channel, impregnating wax in a wax groove, leveling wax liquid in a leveling drying channel, drying wax and sizing, and taking off a wax box from the hanging frame, and is characterized in that the wax liquid for the waterproof wax-impregnated corrugated paper box is prepared from microcrystalline paraffin wax, oxidized polyethylene wax, amide wax, silicon dioxide nano powder, rosin, a surfactant and water. According to the production technology of the waterproof wax-impregnated corrugated paper box, disclosed by the invention, the used wax liquid is a wax composition, has excellent performance of water resistance, wear resistance and the like and has a long life cycle and good stability; in the production technology, heat preservation and heat insulation are carried out so that an energy-saving effect is realized; based on a PLC (Programmable Logic Controller) group control system, automatic flow line production can be realized and the production efficiencyis improved.

Description

technical field [0001] The invention relates to the technical field of production technology of corrugated paper boxes, in particular to a production technology of water immersion wax resistant corrugated paper boxes. Background technique [0002] Corrugated boxes can be seen everywhere in people's daily life. Because of their easy folding, light material and recyclability, hollow breathable and cushioning structure, they have incomparable characteristics of non-corrugated boxes. However, water solubility is a fatal defect of corrugated cartons. It will not only directly cause the corrugated cartons to lose their basic functions, but also mildew and contaminate the items stored in the cartons. tall items. [0003] It has been found that some water-soluble synthetic resins are added to the paper fiber and dried together to greatly improve the wet strength and water resistance. In the 1970s, a lot of research was done on the modification of melamine formaldehyde resin abroad...
