Abstract
A kind of table tennis of novel material, the employing modified polystyrene is a material of main part, mixes softening agent, auxiliary materials such as titanium dioxide and tinting material are made the hemisphere embryo with general plastics machinery, form with solvent bonding again.Table tennis of the present invention is nonflammable, good stability, and period of storage is long.
Description
As everyone knows, existing table tennis is to use the celluloid plastic sheet material, at first makes the ball embryo half, forms through bonding, swollen ball, and the whole production flow process time is long, and the cycle of finished product reached more than 60 days.The zylonite unstable properties is easily lighted, and burning is fierce, and this specific character brings very big danger for production, transportation, storage of finished products, because all very easily cause fire in these links, brings about great losses.Therefore production table tennis producer, International Table Tennis Federation all have a mind and replace zylonite to make table tennis with other plastics.At present, the table tennis of external West Germany, Britain, the state-owned non-celluloid plastic of method, but its hardness, the uniformity coefficient of wall thickness, indexs such as the weight of ball all do not reach the standard-required of table tennis, promptly can not use as table tennis.The domestic table tennis that does not also have non-zylonite.
It is major ingredient that purpose of the present invention will be selected the suitable plastic raw material exactly for use, mixes other auxiliary material again, adopts distinctive operational path and condition to make the plastics table tennis that conformance with standard requires.
Modified polyphenyl table tennis composition of raw materials of the present invention following (by weight percentage, modified polystyrene is one of percentage hundred):
Modified polystyrene 100
Softening agent 1-2
Titanium dioxide 3-5
Tinting material is an amount of
Modified polystyrene can be used high-impact polystyrene polymkeric substance (HIPS) or vinyl cyanide-CALCIUM ACRYLATE-styrol copolymer (AAS).
The technical process of adopting is as follows:
Starting material-→ mixed-→ slice-→ the hemisphere embryo-→ stamping-out-→ cut edge-→ bonding-→ polishing-→ check.
The operation of system hemisphere embryo has two kinds of methods:
A kind of method is a vacuum suction moulding: the sheet material after the slice operation is put the vacuum plastic-absorbing machine heating into, and sheet material was softening after temperature reached 130～140 ℃, began then to vacuumize, and sheet material is sucked into hemisphere embryo mold forming.
Second method is sheet material is subjected to thermal softening in 130～140 ℃ wax liquid after, extrusion forming in hemisphere embryo mould.
Blank operation is that molded hemisphere embryo is rushed out from the monoblock sheet material, and side cut is that the hemisphere embryo is switched to suitable height, preferably 19 millimeters high.
Bonding process be the two hemispheres embryo after the junction surface is with organic solvent dissolution, dock into spheroid.The solvent that recommend to adopt has the solution of butyl ester, ethyl ester, alcohol, or the solution of ethyl acetate, butyl ester, alcohol.The proportioning of two kinds of solution is 4,3 in order, the 1(weight ratio).
Now be illustrated with an example:
Raw material is equipped with: (weight ratio)
High-impact polystyrene polymkeric substance (HIPS) 100
Polyethylene 1
Titanium dioxide 3
After raw material is ready to, put into blender, through stirring material is mixed, then through the plastics extruder slice, sheet is thick in 1～1.2 millimeter scope, and width be decided with needing on board.Sheet material is put into vacuum plastic-absorbing machine, through electrothermal tube even heating to 130～140 ℃, vacuumize then, remollescent sheet material plastic uptake on the hemisphere mould becomes the hemisphere embryo, and every mould can have a plurality of hemisphere moulds, decides on design.
The hemisphere embryo of full wafer cuts out the hemisphere embryo with cutting die after the moulding, and is cut to 19 millimeters high hemisphere embryo through side cut.
The two hemispheres embryo is fixed on the anchor clamps, coats solvent, treat that plastics dissolve back butt joint two hemispheres embryo at jointing end face, dry back the table tennis embryo.Solvent is pressed 4: 3: 1 weight ratio wiring solution-forming with butyl ester, ethyl ester, alcohol.
Table tennis embryo after the bonding is placed in the cylinder, and polishing with silicon sand (No. 240) promptly becomes goods about half an hour, just can dispatch from the factory through being up to the standards.
Starting material of the present invention source is wide, and common plastics processing units is adopted in no particular requirement, and is harmless, pollution-free.Factory does not need special fire protection requirement by the fire safety rules requirement of general plastics factory.
