Embodiment 1

[0046] A paper support processing method, comprising the following steps:

[0047] 1) The semi-finished paper tray is prepared by the paper tray water molding process; wherein, the moisture content of the semi-finished paper tray is 55wt% (wet tray);

[0048] 2) Spray the protective glue on the semi-finished paper holder, and obtain the finished paper holder after drying; wherein, the raw materials of the protective glue include at least water, starch paste, waterproofing agent or aluminum sulfate, and the concentration of the protective glue is 5wt %.

Embodiment 2

[0050] A paper support processing method, comprising the following steps:

[0051] 1) The paper support semi-finished product is prepared by using the paper support water molding process; wherein, the moisture content of the paper support semi-finished product is 60wt% (wet support);

[0052] 2) Spray the protective glue on the semi-finished paper support, and obtain the finished paper support after drying; wherein, the raw materials of the protective glue include at least water, starch paste, waterproofing agent or aluminum sulfate, and the concentration of the protective glue is 15wt%, spray 10-50 grams per 0.1 square meters.

Embodiment 3

[0054] A paper support processing method, comprising the following steps:

[0055] 1) The semi-finished paper tray is prepared by the paper tray water molding process; wherein, the moisture content of the semi-finished paper tray is 58wt% (wet tray);

[0056] 2) spraying or spraying protective glue on the semi-finished paper tray, and drying to obtain the finished paper tray; wherein, the raw materials of the protective glue include water, starch paste, waterproofing agent, aluminum sulfate, and stone powder and dyes; The concentration of the above-mentioned protective glue is 5wt%, spraying or spraying 20 grams per 0.1 square meters; the mass ratio of starch paste, waterproofing agent or aluminum sulfate is 100:1:1.

Abstract

The invention relates to the technical field of paper product production, and particularly discloses a paper holder processing method and application thereof. According to the paper holder processing method, a paper holder semi-finished product is prepared through a paper holder water mold forming technology, then protective glue is directly sprayed outwards, a paper holder finished product which saves materials and materials and is bright in color can be processed, coating, spraying and re-drying of a dry product are not needed, and the process is simple and convenient. Compared with the technical scheme that a semi-finished product is directly produced by pulping and adding a dye auxiliary agent and then is directly dried into a finished product in the prior art, the water pollution caused by dip dyeing can be reduced, the production auxiliary materials and cost are reduced, the effects of not easily fading and dusting, increasing the waterproof and moistureproof rate and enhancing the hardness are achieved, the problems of large wastewater discharge amount and overlarge dye consumption in the existing paper tray production method are solved, and the paper holder processing method has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of paper product production, in particular to a paper tray processing method and its application. Background technique [0002] In daily life and work, people often use paper products. Generally speaking, items made of paper are paper products, such as paper trays, paper cups, pulp lunch boxes, wrapping paper, packing boxes, books, etc. Among them, paper tray (also called pulp molding), as a common environmentally friendly paper product, has good shockproof, anti-shock, anti-static, anti-corrosion effects, and has no pollution to the environment. It is widely used in electronics, electrical appliances, and computers. , mechanical parts, industrial instruments, handicraft glass, ceramics, toys, pharmaceuticals and other industries. [0003] At present, the production methods of paper trays are mostly based on carton scraps, newsprint, white pure wood pulp, etc., after beating and adding dyes, additives (har...
