Abstract
The utility model relates to a synthetic foamed material of gradient structure to hollow microsphere is the obturator, uses the resin as the base member, including synthetic foamed material 2 layers at least, the gradient change takes place with 5% -20% for volume loading that each laminating becomes the interior hollow microsphere of foamed material gradually to the gradient takes place and changes for the performance that makes each laminating become foamed material, like hardness and collision resistance intensity etc. Hollow microsphere's volume loading is counted with the volume percent that hollow microsphere accounted for the foamed material total amount, hollow microsphere is high performance hollow glass microballon, compared with the prior art, the utility model discloses a synthetic foamed material has better energy -absorbing characteristic and shock -resistant ability, and the water absorption rate of material is compared with ordinary synthetic foamed material and is not had the significant change simultaneously.
Description
Technical field
The utility model relates to synthesising foam material, specifically, relates to a kind of hollow glass micropearl filled resin base synthesising foam material of gradient-structure.
Background technology
Synthetic foam is with other microballons such as hollow glass micropearl or potteries for second-phase, take organic polymer as matrix, through mixing, shaping, the composite that is prepared from of solidification.As a kind of Lightweight high-strength composite material of excellent performance, the purposes of synthesising foam material is widely: at marine field, mainly as deep water solid buoyancy material, such as deep-sea underwater operation tool, underwater exploration equipment, drilling riser pipe float the connection protection and marine marker etc. of material, pipeline; At aerospace field, synthesising foam material also can be used as body shell, the material of engine heat insulation layer and the auxiliary member etc. of aircraft.At electronic applications, owing to having excellent electrical insulating property, synthesising foam material is also widely used as electronic devices and components encapsulating material.At building field, synthesising foam material has environmental protection, sound insulation, many performance advantages such as heat insulation; At automotive field, the high energy-absorbing of synthetic foam and shock-resistant characteristic, make it can be used as the bumper material of automobile;
At present, synthesising foam material is the uniform homogeneous material of Density Distribution mostly, the loading of cenosphere usually between 0.3 ~ 0.65, with the low-density making material reach target.Larger relation is there is between the mechanical strength of synthesising foam material and the density of material.Usually, there is more highdensity synthetic foam and show higher intensity and elastic modelling quantity.But highdensity synthetic foam also exists a shortcoming: common high strength synthetic foam has lower breaking strain, corresponding energy absorption characteristics and shock-resistant ability are not as low-density synthetic foam.
In order to increase the energy absorption characteristics of synthetic foam and shock-resistant ability, conventional method in synthesising foam material, adds other elastic granule second-phase, as clay and rubber etc.But owing to introducing new second-phase, the water absorption rate of synthetic foam can obviously increase, very disadvantageous during this application to synthetic foam, be especially danger close when the structural material as submarine and aircraft.
Utility model content
The purpose of this utility model is the weak point solving the existence of above-mentioned prior art, provides a kind of synthesising foam material with the gradient-structure of high energy absorption characteristics and shock-resistant ability.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of synthesising foam material of gradient-structure, take tiny balloon as obturator, take resin as matrix, it is characterized in that: the synthesising foam material comprising at least 2 layers, in each layer synthesising foam material there is graded gradually with 5%-20% in the volume loading of tiny balloon, thus make the performance generation graded of each layer synthesising foam material, as hardness and impact strength etc., the volume loading of tiny balloon accounts for the volume percentage of foamed material total amount with tiny balloon.
Described tiny balloon is high-performance hollow glass micropearl.
Compared with prior art, synthesising foam material of the present utility model has more excellent energy absorption characteristics and shock-resistant ability, and the water absorption rate of material does not have significant change compared with common synthesising foam material simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the synthesising foam material of gradient-structure described in the utility model.
Detailed description of the invention
Fig. 1 is the schematic diagram of the synthesising foam material structure of a kind of gradient-structure of the present utility model, it is made up of 4 layers of synthesising foam material, and each layer of synthesising foam material is all the high-performance hollow glass micropearl of same model is filled into cast in organic resin matrix to form.From the synthetic foam of the 1st layer to the 4th layer, the volume loading of hollow glass micropearl is increased to 40% gradually by 10%.
