Abstract
The present invention relates to a resin composite material pencil. A penholder of the pencil is formed by matching the following components according to weight part: 50 to 70 % of waterborne polyurethane, 10 to 20% of edible starch, 5 to 10 % of micro glass beads, 0.1 to 1 % of nanometer titanium dioxide, 0.5 to 3% of nanometer zinc oxide, 1 to 5 % of zinc stearate, 10 to 15 % of light calcium carbonate and 5 to 10 % of flexible unsaturated polyester resin; a pencil lead of the pencil is formed by matching the following components according to weight part: 10 to 20 % of flexible unsaturated polyester resin, 5 to 10 % of waterborne polyurethane, 10 to 15 % of edible starch, 45 to 85 % of graphite, 0.1 to 0.3 % of nanometer silicon dioxide and 0.05 to 0.2 % of silicon carbide. The resin composite material pencil of the present invention has the advantages of a great deal of wood saving, simple working procedure, energy saving, no lead diverging, good elasticity, fall resistance, break resistance and excellent tactility because materials selected are liquid after being mixed evenly.
Description
Technical field
The present invention relates to the pencil that a kind of new material is made, is resin composite material pencil.
Background technology
At present, China produces about 7,000,000,000 of Wood pencils per year, is equivalent to destroy every year 500 square kilometres of forests, consumes 30 ten thousand stere high-quality timber, has seriously destroyed ecological environment.Occurred pencil made of paper now, pencil raw material made of paper is still timber, therefore, does not fundamentally solve the problem of the destruction Of resources.Multiple plastic pencil is arranged on the existing market, but plastics all contain poisonous composition in various degree, and moulding process is continued to use the expressing technique of plastic products, easy core shift, yield rate is low, no matter from weight, feel, writing effect all less than wooden pencil, plastic pencil is held in the hand the skin discomfort for a long time in addition, also easy endophytic bacteria.
Summary of the invention
The purpose of this invention is to provide a kind of resin composite material pencil, the employing aqueous polyurethane is a primary raw material, adopt scientific formula and manufacture craft, the feature of the existing Wood pencil of making of pencil, filled up the deficiency of plastic pencil again, anti-fall, anti-folding, write lubricious, concentration, abrasion appropriateness, cut the same with Wood pencil.
Resin composite material pencil, comprise penholder and pen core, it is characterized in that penholder is made of by weight ratio following compositions: aqueous polyurethane 50-70, food starch 10-20, glass microballoon 5-10, nano titanium oxide 0.1-1, nano zine oxide 0.5-3, zinc stearate 1-5, precipitated calcium carbonate 10-15, flexible unsaturated polyester resin 5-10;
Pen core is made of by weight ratio following compositions: flexible unsaturated polyester resin 10-20, aqueous polyurethane 5-10, food starch 10-15, graphite 45-85, nano silicon 0.05-0.2, carborundum 0.1-0.3.
The method for making of resin composite material pencil is:
1) at normal temperatures the penholder composition is stirred by weight, use the extruding equipment pultrusion, make hollow penholder, the penholder moulding;
2) under the normal temperature pen core composition is stirred by weight, with injector the liquid that mixes is injected in the penholder then, wrap lacquer with bag lacquer equipment simultaneously.
The advantage of resin composite material pencil of the present invention is: saved a large amount of timber resources, because selected material is a liquid after mixing, operation is simple, saves the energy, and core shift is not flexible, resists and falls, resists folding, good hand touch.
