Description

A kind of integral type football of blown rubber matter

Technical field

The present invention relates to a kind of football, in particular to a kind of integral type football of blown rubber matter, belong to high molecular material and Sports goods technical field.

Background technique

In sports field or gymnastics entertainment field, ball game occupies very big specific gravity.All ball game will make With ball.Such as it is common play basketball, play soccer, playing volleyball, handball, water polo；There are also tennis, shuttlecock, table tennis, softball, Billiard ball.Traditional habit is to be divided into big ball and bead according to ball size and quality used, and big ball therein is exactly alleged by habit " ball for sports class " or ball, mainly include football, basketball, vollyball, and with homogeneous structure other are ball.It passes System structure ball be made of outer layer and inflatable bladder, outer layer be by leather sewn and become covering (or for crust, spherical shell or Spherical surface etc.), inflatable bladder is located inside covering, which is generally made of rubber, and is equipped with gas tube.It is used as movement Ball especially football, the outer layer of ball want athletic ground contact, friction and while by human body acute impacts, can also be subjected to rainwater and The invasion of moisture, this outer layer as made of leather sewn just easily damage, the football rapid wear especially used in place lack of standardization Degree is even more serious.Furthermore the specification and quality standard of football have strict requirements, and the sphere outer layer of this high standard is by several Block leather sews, recruitment cost and production cycle as one can imagine.

Summary of the invention

To solve the technical problem that above-mentioned traditional structure football is easy to damage, high cost and production cycle are long, the present invention is disclosed A kind of integral type football of blown rubber matter.

The technical scheme adopted by the invention is that: a kind of integral type football of blown rubber matter, integral type football is by one The expandable rubber grain of kind is injection moulded the sphere being structure as a whole according to mold, and the expandable rubber grain is by building rubber compound Object and two big groups of rubber chemicals are grouped as, and Rubber compositions are by the polychlorobutadienes of 30 ~ 70 mass parts, 3 ~ 20 mass parts Standard natural rubber, the ethylene-vinyl acetate copolymer of 20 ~ 50 mass parts, the POE elastomer of 1 ~ 15 mass parts, 2 ~ 15 matter Measure the ethylene-propylene diene copolymer or nitrile rubber composition of part；Rubber chemicals component is by the fillers of 0 ~ 20 mass parts, 1 ~ 20 mass parts Reinforcing agent, the dispersing agent of 0.2 ~ 2 mass parts, the modification flowable of 0.5 ~ 3 mass parts, the foaming agent of 1 ~ 5 mass parts, 0.5 ~ 2 matter Measure the vulcanizing agent composition of part；The sphere includes surface layer and base, the upper surface of surface layer have the distinctive equilateral pentagon of football and Equilateral hexagon splicing block and splicing line texture, the upper surface of surface layer there are also pattern and character mark, base the inside of surface layer simultaneously It is structure as a whole with surface layer；Sphere further includes ball ontology and demoulding lid, has demoulding window on ball ontology, the inner circumferential for demoulding window has connection Female groove, the diameter for demoulding window are less than the 20% of sphere perimeter, and the upper surface of demoulding lid is complete sphere making up face and pacify to demoulding window Equipped with air inflation nozzle, there is the public slot of connection in periphery below demoulding lid, connects the connection female groove that public slot is connected to demoulding window by adhesive The sphere of complete integral structure is constituted afterwards.

It is securely whole rubber first the beneficial effects of the present invention are: blown rubber is selected to be injected into integral structure Matter structure outclass leather matter football in all various aspects such as water resistant leaching, moisture resistant, wear-resistant, shock resistance, anti-aging；Followed by It can control the up to standard of sphere weight by the expansion ratio and sphere thickness of rubber；Finally formed by injection (mo(u)lding) machine one injection A large amount of recruitments and material cost can be saved, while can largely shorten the manufacturing cycle.
