Problems solved by technology

The problem with this technique is that it needs to be soaked in potassium aluminum sulfate solution for hardening treatment, and the hardening time is 8 to 24 hours, which increases the production cost of pencils and wastes raw materials

Embodiment 2

[0022] Embodiment 2: the production method of environment-friendly pencil, concrete steps are:

[0023] (1) Paper cutting: Cut waste newspapers into pieces of paper of a certain size, the size of which is 18.5 cm in length and 50 cm in width;

[0024] (2) Glue the pencil lead: wrap the pencil lead with the end of the paper, and then stick it with glue;

[0025] (3) Paper roll: Put the paper with the pencil lead on the conveyor belt of the glue-coating roll machine, and the special glue will be continuously dripped on the paper, and then rolled into a paper rod, which is a hair pencil; The special glue is water-soluble glue, and the proportioning relationship according to mass percentage is: 11.38% white latex, 8.5% sodium fluorosilicate, 0.12% iron dioxide, 40% filler, 40% water;

[0026] (4) Drying: Spread out the rolled pencils and let them dry naturally for 3 hours, then the pencils will harden by themselves and complete the curing process;

[0027] (5) Polishing and cutt...

Abstract

The invention provides a method for producing an environment-friendly pencil. The method comprises the following specific steps of: (1) cutting paper; (2) sticking a pencil core; (3) placing a paper sheet on which the pencil core is stuck on a glue coating pole coiling machine, continuously dripping special glue on the paper sheet and coiling to form a rough pole pencil, wherein the special glue comprises the following components in percentage by mass: 11 to 11.9 percent of acetic acid resin, 8 to 10 percent of sodium fluosilicate, 0.1 to 0.12 percent of ferrum dioxide, 30 to 40 percent of filler and 40 to 50 percent of water; (4) naturally drying the rough pole pencil for 2 to 4 hours; (5) polishing the dried rough pole pencil, and cutting to ensure the pencil has the specified length and size, namely a polished pole pencil; (6) thermally compounding a plastic sleeve on the polished pole pencil; and (7) sleeving an rubber head. The special glue is used during pole coiling, normal temperature solidification is realized and the solidification time is short, the raw materials are saved and production cost of the pencil is reduced. The prepared pencil is environment-friendly and does not pollute the environment.

Description

technical field [0001] The invention relates to a production method of an environment-friendly pencil, in particular to a production method of a rolled-paper pencil. Background technique [0002] At present, most of the pencils used are wooden pencils, which consume a large amount of wood and cause waste of materials. For this reason, there have been pencils that use waste paper (mainly waste newspapers) to roll up the pen holder. For example, the patent application for invention with the publication number CN 1335231A discloses the production process of the environment-friendly waste paper roll pencil. The process flow is: cutting -Rolling rod -Hardened treatment -Thermal composite plastic cover -Set of rubber tips. The problem with this technique is that it needs to be soaked in potassium aluminum sulfate solution for hardening treatment, and the hardening time is 8 to 24 hours, which increases the production cost of the pencil and wastes raw materials.
