Problems solved by technology

In some high-temperature environments, corrugated cardboard easily transfers the absorbed heat to the packaged items, which indirectly reduces the quality of the items; when the corrugated cardboard directly encounters an open flame, it is prone to burning and directly damages Damaged the packaged items, bringing economic losses to people

preparation example Construction

[0019] The preparation method of flame-retardant corrugated paper is as follows: it is composed of a flame-retardant layer, a corrugated paper core, a filling layer and a flame-retardant layer in sequence, specifically, the corrugated paper core is composed of wood pulp, starch and sugarcane stem fiber in a weight ratio of 10: It is made by mixing 4:2:1; after crushing, purification, flotation and refining, the resulting slurry is made to obtain a corrugated paper core; two corrugated paper cores and the fire extinguishing materials placed in them are subjected to high pressure to form a filling layer; After the corrugated paper core and filling layer are pressed together, glue is applied on the surface to form corrugated paper.

[0020] The surface sizing method is:

Embodiment 1

[0022] (1) First, mix 5 parts of melamine, 10 parts of urea, and 5 parts of tricresyl phosphate in parts by weight, and add them to the reaction kettle, and then add 1 part of magnesium hydroxide, 6 parts of calcium borate, 10 parts of Calcium carbonate, heated to 180°C, holding time 1.5 hours;

[0023] (2) Add the above mixture into the hydrothermal tank, and successively add 15 parts by weight of hydroxypropyl distarch phosphate, 11 parts by weight of sodium perborate, a temperature of 85°C, and a reaction time of 2 hours; then add 45 parts by weight of epoxy - Polyurethane glue is stirred to form glue

[0024] (3) After adding water-resistant agent to the glue, stir evenly, then transport the mixed glue to the liquid storage tank, and the glue in the liquid storage tank is directly transported to the sizing machine for surface sizing, and then dried in an oven.

Embodiment 2

[0026] (1) First, mix 10 parts of melamine, 12 parts of urea, and 3 parts of tricresyl phosphate in parts by weight, and add them to the reaction kettle, and then add 3 parts of magnesium hydroxide, 2 parts of calcium borate, and 3 parts of Calcium carbonate, heated to 160°C, holding time 1 hour;

[0027] (2) Add the above-mentioned mixture into a hydrothermal tank, and successively add 22 parts by weight of hydroxypropyl distarch phosphate, 6 parts by weight of sodium perborate, a temperature of 65°C, and a reaction time of 3 hours; then add 30 parts by weight of epoxy - Polyurethane glue is stirred to form glue

[0028] (3) After adding water-resistant agent to the glue, stir evenly, then transport the mixed glue to the liquid storage tank, and the glue in the liquid storage tank is directly transported to the sizing machine for surface sizing, and then dried in an oven.

Abstract

The invention relates to the field of paper making, and particularly discloses a corrugated paper sizing device. The corrugated paper sizing device comprises a reaction kettle, a hydrothermal tank, aliquid storage tank, a sizing machine and an oven; the sizing machine comprises a frame, an upper sizing roller, a lower sizing roller, an upper sizing pipe and a lower sizing pipe; the reaction kettle is connected with the hydrothermal tank; the hydrothermal tank is connected with the liquid storage tank; a glue liquid is stored in the liquid storage tank; the liquid storage tank is connected with the upper sizing pipe and the lower sizing pipe; the frame is positioned between the upper sizing pipe and the lower sizing pipe; and each sizing roller is arranged at a position beside one corresponding sizing pipe and on the frame. After the glue liquid is sprayed onto a paper surface by the sizing pipes, compaction is carried out by the sizing rollers, and the paper is conveyed into a dryingoven through the frame for drying, and sizing layers are formed. According to the corrugated paper sizing device provided by the invention, a flame-retardant layer can be effectively formed on the corrugated paper, so that the safety of the corrugated paper packaging is improved.

Description

technical field [0001] The invention relates to the field of papermaking, and specifically discloses a corrugated paper sizing device. Background technique [0002] The protection of packaging materials to the quality of the contents is one of the main functions of packaging, and the inner packaging plays a vital role in the protection of goods. [0003] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated paper core layer and one layer of cardboard. Corrugated cardboard has high mechanical strength and can withstand collisions and falls during cargo handling. It is mainly used to make cartons and outer packaging of fragile goods. [0004] At present, corrugated cardboard is mainly made of fiber base paper, which is easily affected by external environmental factors such as humidity and temperature. In some high-temperature environments, corrugated cardboard easily transfers the absorbed heat to the packaged items, which in...
