Abstract
Collide with each other not bad racket the invention discloses frame, it is made of frame, middle pipe and handle, it is characterized in that: the frame is formed by carbon fibre composite injection moulding, frame elder generation after molding grinding process, it is drilled all threading nail hole again, then sprays the polyurea coating that upper a layer thickness is 50 ~ 500 μm；The polyurea coating is to react a kind of elastomer coatings generated with amino-compound component by isocyanate component.By experiment, it was concluded that: as long as spraying the polyurea coating that upper a layer thickness is 50 ~ 500 μm in battledore frame, replace conventional coatings, both without additionally increasing bat weight, it is can guarantee again when bat collides with each other, be will not cracking, still can be used normally.The present invention is without additionally increasing bat weight, and in badminton doubles campaign, if the bat between teammate collides with each other, frame be will not cracking, and bat still can be used normally.
Description
Technical field
It collides with each other not bad racket the present invention relates to a kind of racket more particularly to a kind of frame.
Background technique
The frame of well known racket is all carbon fiber or aluminum, and the coating on frame has been beauty function.?
In badminton doubles campaign, the bat between teammate often collides with each other, and frame is caused to crack, and bat is made to lose use value.
Summary of the invention
In order to overcome above-mentioned deficiency, collide with each other not bad racket the present invention provides a kind of frame.
Present invention technical solution used for the above purpose is:
Frame collides with each other not bad racket, is made of frame, middle pipe and handle, it is characterized in that:
The frame is formed by carbon fibre composite injection moulding, frame elder generation after molding grinding process, then is drilled all wear
Then tailor's tack hole sprays the polyurea coating that upper a layer thickness is 50 ~ 500 μm；The polyurea coating be by isocyanate component with
A kind of elastomer coatings that the reaction of amino-compound component generates.Test proves that polyurea coating have good waterproofness,
Tensile strength, flexibility, wearability, anti-corrosive properties are sprayed the polyureas that a layer thickness is several millimeters to more than ten millimeters on military vehicle and are applied
Layer can be shellproof.By experiment, it was concluded that: as long as spraying the polyureas that upper a layer thickness is 50 ~ 500 μm in battledore frame
Coating replaces conventional coatings, not only without additionally increase bat weight, but also can guarantee when bat collides with each other, will not cracking, still
So it can be used normally.Polyurea coating has sprayed thick can increase cost too much, and can additionally increase weight and cause bat not firm
With.
The invention has the advantages that the present invention is without additionally increasing bat weight, in badminton doubles campaign, teammate
If bat between collides with each other, and frame will not cracking, and bat still can be used normally.
Detailed description of the invention
The present invention is further described with implementation with reference to the accompanying drawing.Fig. 1 is schematic diagram of the invention.
In figure, 1 is frame, and 2 be middle pipe, and 3 be handle, and 4 be polyurea coating.
Specific embodiment
In Fig. 1, frame collides with each other not bad racket, is made of frame 1, middle pipe 2 and handle 3, it is characterized in that:
The frame 1 is formed by carbon fibre composite injection moulding, frame elder generation after molding grinding process, then is drilled all wear
Then tailor's tack hole sprays the polyurea coating 4 that upper a layer thickness is 100 μm；The polyurea coating 4 is by isocyanate component and ammonia
A kind of elastomer coatings that the reaction of based compound component generates.Test proves that polyurea coating 4, which sprays, can make frame on frame 1
With good waterproofness, tensile strength, flexibility, wearability, anti-corrosive properties.The present invention is in badminton doubles campaign, teammate
If bat between collides with each other, and frame will not cracking, and bat still can be used normally.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form, appoint
What without departing from the present invention program content, according to the technical essence of the invention any simple modification to the above embodiments, etc.
With variation and modification, all of which are still within the scope of the technical scheme of the invention.
