Abstract
The present invention relates to a new type pencil. The main component of its pencil shaft is pencil stirp which is similar to wood and is made up by using modified PVC resin through injection moulding process, and the pencil lead is placed between two pencil strips, then the above-mentioned materials are hot-pressure welded together by heat-sealing machine so as to obtain the invented product. Said invention uses no wood, and its service performance is identical to that of pencil with wooden shaft.
Description
The present invention relates to the pencil in the writing implement, be meant the pencil that a kind of new material that can replace timber is made especially.
After this rod pencil appearred in Britain in 1565, up to now, pencil was served nearly 500 years for the mankind, and a kind of overall plastic pencil once appearred in the sixties in this century, and the seventies begins to occur automatically thin pencil.The 60 overall plastic pencils to the seventies development appearance, its dominant ideas are want exactly to replace the art material with a kind of substitute materials for wood, and are reached the function equal with Wood-bar pencil.Its Main Ingredients and Appearance is: the penholder pellet uses thermoplastic resins such as polystyrene, polypropylene, ABS to manufacture; The lead for retractable pencil pellet is made binding agent with polystyrene, polypropylene, ABS, and graphite is made colouring agent and made.Two kinds of pellets are through hot extrusion, and outward appearance processing is carried out in one-shot forming after cooling, the cut-out, make overall plastic pencil.The pencil of this explained hereafter can be saved timber, but lead for retractable pencil concentration is not so good as Wood-bar pencil, and writing effect is undesirable, and the cost height, so do not promoted the use of.(seeing " pencil production technology " Chinese Ministry of Light Industry volume, 87 years versions), thereby, still be two big classes in the current pencil, the one, propelling pencil, the 2nd, this rod pencil.Making Wood-bar pencil needs a large amount of high-quality timber, because global felling has at present made area of woods reduce in a large number, ecological disequilibrium jeopardizes environment for human survival.Yet, the advantage of Wood-bar pencil itself is again that propelling pencil is irreplaceable, therefore, and in the day by day deficient world today of timber resources, be badly in need of a kind of new material and technology that can substitute timber and make pencil, and the performance of this pencil should be identical with Wood-bar pencil.
Purpose of the present invention will provide a kind of new material and corresponding production technology exactly, makes a kind ofly can replace timber, and its performance is with the same novel pencil of Wood-bar pencil.
The object of the present invention is achieved like this: with the modified PVC resin is that the pencil plate of similar wood is produced in filler, reinforcing agent, plasticizer, colouring agent, essence, injection moulding to Main Ingredients and Appearance in addition, place lead for retractable pencils in the middle of two pencil plates, by heat-conglutinating machine pressing welding and be made into pencil.
The present invention is owing to adopted new material and corresponding production technology, the pencil of making is saved timber, make simultaneously produce Wood-bar pencil 50 surplus procedure be kept to 20 surplus procedure, and direct cost is identical with Wood-bar pencil, because process drum is single, take up an area of less, the cycle is short, so integrated cost can be lower than Wood-bar pencil, its raw material also obtains easily.Compare with overall plastic pencil, it does not change the production technology of Wood-bar pencil lead for retractable pencil, because lead for retractable pencil is identical with the rod lead for retractable pencil, thus do not influence writing effect, and can make different moulds according to the shape of lead for retractable pencil, to adapt to the production of different size pencil.
Concrete material of the present invention constitutes and production technology is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the schematic diagram of the general pencil plate of the present invention's production.
Describe the material composition and the corresponding production technology of the novel pencil of the present invention's proposition in detail below in conjunction with Fig. 1.
The penholder Main Ingredients and Appearance of novel pencil is the modified PVC resin, add o-phthalic acid dibutyl ester, filler is as useless tangerine bar powder in the useless red soil of calcium carbonate, flyash, aluminium metallurgy, the useless plaster of copper metallurgy, the agricultural-product or the like, reinforcing agent such as glass fibre, the epoxy-stabilized plasticizer, and according to the different colouring agents and different essence of technological requirement selection.Above-mentioned raw materials is made into pellet through processing.Specification, shape mfg. moulding die according to pencil, be injection molded into the same plastic plate that has groove 1 of similar wooden pencil plate through injection machine, in the groove of a plastic pencil, place lead for retractable pencil, another piece plastic pencil plate in the pressing uses high-frequency thermocompressor or induction heat-sealing machine that two blocks of plastic pencil plates are welded together together with the lead for retractable pencil pressing that is placed in the groove again.A plurality of heat-sealing machines are linked together, just can form continuous productive process, produce and to roll up the novel plastic pencil of cutting.
Through the pencil that this kind technical method is produced, timber can be saved, and the novel pencil of difformity, different color, diverse fragrant flavour can be produced, this pencil can directly use rotor or other cutter volume to cut use.
Claims (6)
1, a kind of novel pencil, with the modified PVC resin is Main Ingredients and Appearance, add o-phthalic acid dibutyl ester, and filler, reinforcing agent, plasticizer, colouring agent, essence become the plastic pencil plate of the similar wooden pencil utmost point through mixed injection molding, groove in the middle of the two boards is placed lead for retractable pencil, uses high-frequency thermocompressor or the pressing of induction heat-sealing machine to weld together.
2, novel pencil according to claim 1 can use pencil sharpener or the direct volume of other cutter to cut.
3, novel pencil according to claim 1 can utilize different moulds to manufacture the pencil that can insert and put the different size lead for retractable pencil as required.
4, novel pencil according to claim 1 can utilize different moulds to manufacture various special-shaped outward appearances as required.
5, novel pencil according to claim 1 can add the pencil that different colorant manufactures the different color penholder as required.
6, novel pencil according to claim 1 can add the pencil that different essence manufacture diverse fragrant flavour as required.
