Description
Technical field
The present invention relates to a kind of basketball preparation technology, belong to sports equipment preparing technical field.
Background technology
Basketball be youngster like one of ball, basketball divides ball sewed by hand and sticky ball, is most commonly that lagging basketball, by
Inner bag, epidermis, ball mouth etc. are made.Inner bag i.e. bladders, is the heart of ball, in the innermost layer of ball, is made up of black rubber；Table
Skin is divided into synthesis skin (ultra-fine strong fiber, PU, PVC etc.) and corium；Ball mouth is for inflating to ball.But current common patch
Skin basketball outward appearance, epidermis has 8 ball ridge, and the leather causing the rubber sense of touch on its ball ridge and laminating is different, and jumping degree is uneven
One, outward appearance, feel are the best.
Summary of the invention
The invention aims to solve the rubber stem bar that the stem bar part of existing basketball usually exposes easily occur always
Changing and cause the elastic bad problem of basketball, it is provided that a kind of method simple basketball preparation technology, the basketball prepared uses to be sent out
Bubble polyurethane PU leather is crust, and stem strip adoption PU removes from office laminating, comfortable feel sphere good springiness.
The present invention adopts the following technical scheme that basketball preparation technology, comprises the steps:
(1) selecting polyurathamc PU leather is raw material, and cuts out 8 ~ 12 pieces of polyurathamc PU according to the specification of bladders
Leather crust, then the edge chamfered edge 3 ~ 4mm by every piece of polyurathamc PU leather crust, and to make the edge tilt angle after chamfered edge be 14
~ 15 °, PU leather is then selected to be cut into 4 ~ 8 stem bars；
(2) using throwing hair machine automatically that bladders carries out throwing hair, the throwing hair time is 10 ~ 12min, cleans foreign material；
(3) in the polyurathamc PU leather cut and the back side brush ground floor glue of stem bar, the quality of ground floor glue
Percentage concentration is 20 ~ 25%, then at polyurathamc PU leather and the back side brush second layer glue of stem bar, described second layer glue
Mass percentage concentration be 60-66%, naturally dry under room temperature condition, the time is 1 ~ 2min；
(4) at the outer layer brush two-layer glue of bladders, the mass percentage concentration of ground floor glue and second layer glue is 20 ~
25%, under room temperature condition, bladders dries naturally, and the time is 1 ~ 2min；
(5) bladders being placed in baking oven heating, oven temperature is 40 ~ 45 DEG C, first will coat the stem bar part of glue successively
It is attached on bladders, uniform winding, then the polyurathamc PU coating glue is removed from office and bladders pre-bonded；
(6) spheroid of pre-bonded is put in the mould in vulcanizer and carry out basketball sulfidization molding, make polyurathamc PU
The stem bar of the crust of leather and PU leather bonds further with bladders, and mold temperature is set to 40 ~ 50 DEG C, and cure time is 2 ~ 3min；
(7) basketball after sulfidization molding is removed from the molds, in basketball inner bag, is charged to 8 ~ 9 pounds of air pressure, naturally parks
40 ~ 48 hours, glue is made to play consolidation.
Further, outside the leather in described step (1), use the LOGO of high-frequency hot-pressing basketball, High frequency heating
Temperature is 70 ~ 80 DEG C.
Further, the solvent of the ground floor glue in described step (3) and step (4) and second layer glue is organic molten
Agent toluene or ethyl acetate.
Further, the solute of the ground floor glue in described step (3) and step (4) and second layer glue is for connecing lipid
CR glue.
Preparation technology of the present invention is simple, and the stem strip adoption PU leather of basketball is made employing glue and is bonded on bladders, it is to avoid
The aging comfortable feel degree caused of black rubber stem bar exposed declines, and the elastic bad phenomenon of sphere uses polyurathamc
PU leather prepares the crust of basketball, basketball elastic more preferably and crust each block leather color can arbitrarily be arranged in pairs or groups fashionable appearance, basketball
Inner bag is rear sulfidization molding simultaneously together with crust pre-bonded, makes crust laminating more firm.
