Abstract
A table tennis ball is made up from low-pressure polyethylene, modified polystyrene and polycarbonate through heating plastics, hollow extruding to obtain hollow bar, inflating, and die pressing for shaping. Its advantages are no pinhole and low cost.
Description
Technical field:
The present invention relates to the sports goods field; Refer in particular to a kind of novel table tennis and the preparation method of Qi Xin.
Background technology:
Former table tennis material adopts the celo road, and this material is decided to be dangerous material (wildfire product) by the country and the whole world, and transportation is difficulty very; And former manufacture craft adopts the boiler heating, and the steam punching press is heated while cool off, and is shaped complex process then.And it is very big to produce celo road goods equipment investment, needs more than 1,000,000.The object of the present invention is to provide a kind of nonflammable explosive and technology is simple, a kind of table tennis and its preparation method that cost is low.Material of the present invention adopts plastic products, has thoroughly solved an inflammable easily sudden and violent difficult problem, is convenient to transportation; And adopt new technology of the present invention, and invest nearly 80,000 yuan, equipment cost reduces by 90% than celo road goods, the goods cost reduces by 40%, and by mould air is entered in the table tennis, increases elasticity, and whole ball shows no sign of pinprick, and air is fully within the sealing of table tennis.Cost of the present invention is low, technology is simple.
Summary of the invention:
The present invention is achieved by the following technical solution: this table tennis material adopts plastics, and the material of employing is the low pressure PEF, modified polyphenyl is rare and Merlon; Its new preparation method is that plastics heat through barrel earlier, and front-end temperature is controlled between 120-150 ℃, stage casing temperature 150-180 ℃, and 200-210 ℃ of back segment temperature; Save head through the angle hollow mould then and carry out the extrusion molding hollow mould and save, raw material becomes the strip of hollow, carries out progressive die twice through secondary progressive die machine again, and pipe is saved air inlet for the first time, charges into a gas pressure 3-8 air pressure, the spherical cavity moulding second time.
Description of drawings:
Fig. 1 is a kind of preparation method's simple block diagram of table tennis.
The specific embodiment:
As shown in the figure, get an amount of high density low pressure PEF and be introduced into barrel heating, front-end temperature is at 130 ℃, again through 160 ℃ of stage casing temperature, after 200 ℃ of back segment temperature; Heating is after the angle hollow mould is saved head carries out the extrusion molding hollow mould and save; the strip of sky in the middle of raw material becomes; carry out the secondary progressive die through secondary progressive die machine again; charge into for the first time air; charging into gas pressure is 6 air pressure; the spherical cavity moulding has formed a resilient table tennis of no pinprick for the second time.
