Abstract

The invention discloses a wood pen holder and a manufacturing method thereof, which relates to a manufacturing method of a writing tool, belonging to the technical field of miscellaneous wood molding and processing. The wood pen holder is characterized by comprising the following components in percentage by weight: 50-80 percent of hard miscellaneous wood raw material, 4-15 percent of various sawdust, 5-10 percent of various shavings, 2-5 percent of various wood dust, 4-10 percent of polyhydroxyalkanoate, 3-5 percent of starch, 1-7 percent of cross-linking agent and 1-3 percent of plasticizer. The invention has the advantages that a large quantity of waste forest harvesting trees and miscellaneous wood are used as main production raw materials, so that the limits of raw material tree varieties are avoided, the tree variety raw materials can be flexibly collocated so as to meet the requirement on low cost production; the production cost not only can be reduced, but also the mechanical strength of produced wood plates can be guaranteed to conform to the wood panel standard of the Sweden; and meanwhile, after the forest harvesting trees and miscellaneous wood are utilized, a greater economic benefit not only can be directly generated by manufacturing enterprises, but also forest fires and pest and disease damages can be reduced, which is helpful to the ecological cycle.

Description

technical field [0001] The invention relates to a method for making a writing instrument, which belongs to the technical field of miscellaneous wood molding and processing, in particular to a wooden pencil holder and a method for making the same. Background technique [0002] Pencils consist of strips of lead embedded in a wooden barrel. The barrel of a pencil is generally made of wood. When making the barrel, a lot of cutting processes are required to make the log into a round, regular hexagonal or regular octagonal penholder. The process is quite cumbersome, the production cost is high, and a lot of waste The consumption of a large amount of forest resources is very detrimental to the increasingly fragile ecological environment. [0003] In recent years, pencil manufacturers have developed pencils using paper pen holders in order to reduce the amount of wood used, but the original material of many papers is still wood, so this paper pen holder is equivalent to indirectly ...
