It the utility model is related to expanded material technical field, more particularly to a kind of closed cell foamed material, including body, the body is integrally formed to be continuous foamed, the body includes epicuticle, center core layer and lower epidermis, the epicuticle, center core layer and lower epidermis are that continuous closed-cell foam is integrally formed, and the epicuticle is smooth surface or is boss surface with lower epidermis, and the center core layer is the closed pore state that is evenly distributed；The utility model does not have to electron irradiation and is crosslinked and is continuously chemically crosslinked closed-cell foam without being molded can, and with more nonpoisonous and tasteless, antibacterial is wear-resisting pressure-resistant and flame retardant effect, and the method particularly complies fully with EU criteria in terms of formamide and user requires.
Description
Technical field
Expanded material technical field is the utility model is related to, more particularly to a kind of closed cell foamed material.
Background technology
Expanded material is with raw material such as plastics (PE, EVA, POE EPDM etc.), rubber (SBR, CR etc.), is catalyzed
The auxiliary materials such as agent, stabilizer, foaming agent, foamed by being chemically crosslinked, make occur a large amount of trickle foams in plastics and rubber, volume increases
Add, density reduce, flexible foamed quality of materials is light, pliability is good, possess buffering, sound-absorbing, shock-absorbing, insulation, etc. function, extensively answer
For industries such as electronics, household electrical appliances, automobile, Leisure Sports.
But the shortcomings of existing expanded material density is big, and price is high limits its use range.How expanded material is kept
Feature performance benefit, and avoid its performance shortcomings, while reduce production cost, be always the hot issue of industry research；
Know that closed-cell foam technology IXPE needs electronic crosslinking just to have preferable foaming effect, the big leakiness of XPE foam holes, relative to IXPE
Foaming does not need electron irradiation crosslinking, without the high cost of used device.
Utility model content
To solve the above problems, the utility model offer is a kind of without electron irradiation crosslinking and continuous without being molded can
Chemical crosslinking closed-cell foam, with more it is nonpoisonous and tasteless, manufacturing cost is low, antibacterial is wear-resisting pressure-resistant and flame retardant effect, particularly exist
The closed cell foamed material of EU criteria and the limit value of user's requirement is complied fully with terms of formamide.
Technical scheme is used by the utility model：A kind of closed cell foamed material, including body, the body are continuous
Foaming is integrally formed, and the body includes epicuticle, center core layer and lower epidermis, and the epicuticle, center core layer and lower epidermis are company
Continuous closed-cell foam is integrally formed, and the epicuticle and lower epidermis are smooth surface or embossed surfaces, and the center core layer is provided with hole
Shape body.
Further improvement of these options is, the poroid body is closed hole body, the poroid body diameter phase
Together.
Further improvement of these options is that the poroid body diameter scope is in 0.01~0.2mm.
The beneficial effects of the utility model are：
Closed cell foamed material includes epicuticle, center core layer and lower epidermis, and the epicuticle, center core layer and lower epidermis are continuous
Closed-cell foam is integrally formed, and is integrally formed by continuous foamed, and expansion density is high, high mechanical strength, is simple to manufacture, cost
Low, the product appearance for foaming out is identical with IXPE and EVA moulded from foam, the closed-cell foam material of specially a kind of chemical crosslinking
Material, electron irradiation crosslinking is not needed relative to IXPE foaming, without the high cost of used device；Moulded from foam is because can not continuous metaplasia
Production, causes cost of labor and energy consumption higher；Specifically to solve the smell of material, antibacterial flame-retardant；Foaming material can further be improved
The expansion density of material, expansion density are high, and cost is low, and with more nonpoisonous and tasteless, antibacterial is wear-resisting pressure-resistant and flame retardant effect, this side
Method particularly complies fully with EU criteria in terms of formamide and user requires.
Brief description of the drawings
Fig. 1 is structure schematic diagram of the present utility model.
Accompanying drawing identifies：Body 100, epicuticle 110, center core layer 120, lower epidermis 130, poroid body 140.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.
As shown in figure 1, it is schematic diagram of the present utility model.
A kind of closed cell foamed material, including body 100, the body 100 are integrally formed to be continuous foamed, the body
100 include epicuticle 110, center core layer 120 and lower epidermis 130, and the epicuticle 110, center core layer 120 and lower epidermis 130 are company
Continuous closed-cell foam is integrally formed, and the epicuticle 110 and lower epidermis 130 are smooth surface, and the center core layer 120 is provided with poroid
Body 140.
The continuous closed-cell foam of the utility model is integrally formed, the product appearance for foaming out and IXPE and EVA moulded from foam
It is identical, specially a kind of closed cell foamed material of chemical crosslinking, electron irradiation crosslinking is not needed relative to IXPE foaming, without throwing
Enter the high cost of equipment；Moulded from foam causes cost of labor and energy consumption higher because being unable to continuous production；Specifically to solve material
Smell, antibacterial flame-retardant；The expansion density of expanded material can be further improved, expansion density is high, and cost is low, with more nothing
Poison is tasteless, and antibacterial is wear-resisting pressure-resistant and flame retardant effect, and the method particularly complies fully with EU criteria and user in terms of formamide
It is required that.
The poroid body 140 is closed hole body, and the poroid body diameter is identical, and closed pore formula hole body, which has, to be recovered to imitate
Rate is high, density is big and other effects.
For the diameter scope of poroid body 140 in 0.01~0.2mm, preferably 0.1mm, density is big, and bubbling efficiency is high,
Manufacture efficiency is high.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
