Abstract

The invention discloses an environment-friendly breakage-resistant pencil which comprises a penholder and a pencil lead. The penholder is made of plant straw, and the pencil lead is tenacious. The plant straw, adhesive and salt are uniformly mixed and are manufactured into the required pencil via steps of squeezing, forming, cutting pencil lead filling, sterilizing, drying, grinding, polishing, coloring and the like. The environment-friendly breakage-resistant pencil has the advantages that fibers which are widely available in nature can be used as manufacturing raw materials, wood is omitted, forests can be effectively protected, the manufacturing cost of the pencil can be reduced, and the internal pencil lead can be prevented from being broken due to falling.

Description

The anti-pencil that falls of a kind of environmental protection

Technical field

The present invention has designed a kind of pencil, and particularly a kind of novel environment friendly is anti-falls pencil, belongs to articles for writing or realia field.

Background technology

Timber is the precious resources of country, also is material in short supply, and all trades and professions all how studying to save timber, are sought substitute for wood, and general pencil adopts wood pen holder, and its material consumption timber is large, is unfavorable for environmental protection.Wood pencil processing and manufacturing process is complicated, pollutes greatly, and cost is high, and quality control is difficult, the less variation of outward appearance, and pen core is toxic.Children use or easily broke when playing, and pen core is write difficultly, and coloring is relatively poor.

Summary of the invention

The objective of the invention is to remedy above-mentioned deficiency, cheap, good springiness is provided, easy fracture not, the anti-pencil that falls of the environmental protection of alternative timber.

Technical scheme of the present invention is: this pencil comprises penholder and pen core, and penholder is by the straw manufacturing, and pen core is the toughness pen core.With straw, adhesive and salt mixing, namely make required pencil by steps such as extruding, moulding, cutting, dress pen core, sterilization, oven dry, polishing, polishing, colourings.

Compare with existing product and not only can utilize fiber that nature extensively exists for making raw material, need not use timber, both can effectively conserve forests, also can reduce the cost of manufacture of pencil, and can avoid because falling the situation that inner pen core was broken of bumping.

Specific implementation method

Below in conjunction with accompanying drawing the present invention is described in further detail:

At first make the toughness pen core: get 45 parts of graphite powders, 18 parts of polystyrene, 10 parts of polyethylene, 4 parts of haloflexes, 2 parts of calcium stearates, 4 parts of stearic amides, it is even to put into container for stirring, then pours into and carries out extrusion modling in the pen core mould, dries rear for subsequent use.

Next makes penholder.

1, straw is cleaned, is dried and smash to 70 orders;

2, with 70 parts of stalks pulverizing and 15 parts of binding agents, 0.2 part of salt, put into container and stir, obtain compound;

3, compound is poured in the pen core mould shaped the machine moulding through multifunction straw again, make hollow blank, cut into again the length of pencil commonly used, then insert pen core and get final product.

Claims

1. the present invention has designed that a kind of novel environment friendly is anti-to fall pencil, and it is characterized in that: penholder is by the straw manufacturing, and pen core is the toughness pen core.

2. pencil according to claim 1 is characterized in that: its proportioning of the prescription of toughness pen core: 45 parts of graphite powders, 18 parts of polystyrene, 10 parts of polyethylene, 4 parts of haloflexes, 2 parts of calcium stearates, 4 parts of stearic amides.
