Abstract
The invention relates to an artificial feather for a badminton, which consists of a feather stem (11) and a pinna (12). The whole or part of the artificial feather is made of micropore foamed plastics, and particularly micropore nylon foamed plastics or micropore polycarbonate foamed plastics, wherein the feather stem (11) or the pinna (12) also can be provided with an embedding piece additionally. The invention also relates to the badminton made of the micropore foamed plastics.
Description
Technical field
The present invention relates to a kind of artificial feather that is used for shuttlecock.The invention still further relates to the shuttlecock that employing is made with a kind of technical scheme.
Background technology
Replace poultry feather to make the high-performance shuttlecock with artificial material is to be stranded a technical barrier of scratching industry always.The performance of existing baton round obviously is difficult to satisfy shuttlecock fan's requirement.Since the eighties in last century, just there is mechanism to study artificial simulated feather.The artificial feather that just occurred industrialization up to 2010, but performance is still difficult fully up to expectations---mainly be overweight, and manufacturing process is mainly by artificial, efficient is very low.
All problem cruxs are summed up as one entirely: the balance that is exactly mechanical strength and weight.Shuttlecock is very high to the requirement of spheroid weight and distribution of weight, and general standard uses ball and weight in 4.7～5.2 gram scopes, and the heavily reason of single feather is advisable to be no more than 0.13 gram.Under the weight and distribution of weight prerequisite that guarantee this, require the plumage stalk and the accessory pinna of feather that very high mechanical strength and anti-strike ability are arranged simultaneously.Adopt conventional artificial material, weight is up to standard often, but mechanical strength is not enough, otherwise mechanical strength is much of that, and is then seriously overweight.
The technical scheme of in highstrenghtpiston's tubule filling foamed plastics or hollow beads is proposed on July 29th, the 2009 disclosed patent specification 2008100085837.But in implementation process, find, in the small scale space, obtain stable foaming body, on technology, be difficult to.If adopt the microporous foam technology then can address these problems well.It is pointed out that microcellular foam and conventional foam plastics are diverse two kinds of technology products, can not simply be equal to.
The tradition foam process is to adopt physical blowing agent and nucleator or CBA to bring out uneven nucleation in material and foam, and cell diameter generally surpasses 250 μ m.
The microporous foam technology is different with traditional foaming technique, do not need CBA or physics nucleator, it is to utilize supercritical gas to produce in polymer melt to be evenly distributed and a kind of novel foaming technique of the small pore that size is more consistent, general cell diameter is below 100 μ m, typical cell diameter can also be littler at 5～50 μ m.
The conventional foam plastics are compared with not foamed plastic of the same race, and the decline of indexs such as its stretch modulus, rigidity, bending strength is exponential.And microcellular foam is compared with former plastics, and the decline of mechanical strength is then much smaller.Microcellular foam is compared with the regular-type foam plastics, show a lot of excellent comprehensive performances, for example have high impulse strength, fatigue strength and heat endurance etc., have a wide range of applications in industries such as packing, building, automobile, Aero-Space and sports equipments.
Micropore injection moulding technology and routine not frothing injection technology are compared a lot of advantages are also arranged, such as, lower clamp force and lower mold temperature.Therefore be particularly suitable for injecting thin-gage goods.Can easily inject wall thickness and have only 0.22mm, melt flows length and wall ratio up to 280 moulding.And these technology just the integral molded plastic artificial feather need.Adopt the micropore injection moulding technology to produce the equilibrium problem that artificial feather can solve intensity and weight well.
The present invention does not repel with other foaming method obtain the aperture uniform relatively foamed plastics that distributes below 100 μ m.
Summary of the invention
The technical problem to be solved in the present invention is to be provided for the artificial feather of shuttlecock.Another technical problem that the present invention will solve provides the artificial material shuttlecock of excellent performance.
For solving the problems of the technologies described above, artificial feather of the present invention is made up of plumage stalk and accessory pinna two parts.The integral body of artificial feather is all made by microcellular foam, also can be that wherein a part is made by microcellular foam, and one of obstructing among both such as accessory pinna or plumage is to be made by microcellular foam.Simultaneously, accessory pinna or plumage stalk can embed other material again, such as embedding fibre-reinforced composite bar in the plumage stalk, form the suitcase cored structure, to increase its rigidity, improve the shuttlecock performance.
Shuttlecock of the present invention comprises bulb and spherical crown, also has fixing collar generally speaking.The microcellular foam that can adopt in whole or in part of shuttlecock is made.
The most frequently used situation is that the spherical crown of shuttlecock partly adopts microcellular foam to make.Can be divided into two types again haply: the one, adopt above-mentioned artificial feather system ball; The 2nd, with the spherical crown integral molded plastic, disposal molding comprises ball skirt and ball skirt pole part, can also embedded reinforcement in the ball skirt pole.The shape of system technology of ball and ball respectively with the goose duck feather ball and the plastic shuttlecock analogy of routine.
The bulb of same shuttlecock also can adopt microcellular foam to make.
Above-mentioned microcellular foam can adopt nylon plastic(s) or polycarbonate plastic as matrix.
Artificial feather of the present invention and shuttlecock have high-strength light, the characteristics that durability is good.
