Abstract
The present invention provides thermosetting resin extremely-low density laminated material and preparation method thereof, thermosetting extremely-low density laminated material through being laminated heat cure after reinforcing material dipping mixed glue solution by being obtained, mixed glue solution includes hollow glass micro-ball, suspension stabilizer, anti-phase separation agent, dispersant, epoxy resin, curing agent, accelerator and solvent, spatially stable network structure is formed after causing hollow glass micro-ball and mixed with resin parcel due to the suspension stabilizer added in mixed glue solution, beneficial to holding hollow glass micro-ball stable suspersion in resin；The addition of anti-phase separation agent causes that hollow glass micro-ball mixes in stable resin；And dispersant promotes dispersion of the hollow glass micro-ball in resin, improve the adhesive force and dispersed stability in resin of hollow glass micro-ball, substantial amounts of addition can be such that epoxy resin composite material significantly mitigates, have the characteristic of fibre reinforced materials concurrently simultaneously so that laminated material quality of the invention it is lighter while with suitable intensity.
Description
Technical field
The present invention relates to thermoset ting resin composite technical field, more particularly to thermosetting resin extremely-low density lamination material
Material and preparation method thereof.
Background technology
Thermosetting laminated material be by two-layer or multilayer be soaked with the fiber or fabric of resin through overlapping, hot binding into it is whole
Body.Thermosetting laminated material can be processed into various insulation fabric parts, be widely used in motor, transformer, high and low voltage electrical equipment, electrician
In instrument, electronic equipment and in consumer electronics shell and containment vessel.
With low-carbon (LC) life, low-carbon economy, low carbon society development, material lightweight especially composite light weight chemical conversion
For direction is expanded in the very powerful and exceedingly arrogant research of today's society.
The light-weighted demand of consumer electronics equally leads the frivolous high strengthening of consumer electronics material to develop, except reduction material thickness
(electronic product slimming has developed for many years, is confined to electronic product overall permanence, and the space of material slimming has run into bottle outward
Neck), the density for reducing material is also feasible effective way, conventional thermosetting lamination high strength composite density about 1.6g/
cm3, very powerful and exceedingly arrogant in recent years Lightweight high-strength composite material density about 1.0g/cm3, also have density in 1.0g/cm3It is following
Material but it is limited by that bulk strength is not high, application limitation is big.Developing density 1.0g/cm3Following intensity composite again high
It is currently to be badly in need of the problem to be solved.
Such as Patent No. 201310230879.4, patent name is：Laminated material and preparation method thereof is micro- with hollow glass
The application of ball, it is using thermosetting resin addition glass microsphere dipping inorfil reinforcing material warp to disclose a kind of laminated material
Hot pressing and obtain, specific practice is：Epoxy resin, solvent, curing agent, tiny balloon are made into mixed glue solution；Reinforcing material is put
Impregnated in the mixed glue solution, baking, then prepreg is obtained through cooling；A piece of above prepreg is laid out, and
Prepreg two sides after stacked is respectively covered with one layer of mould release membrance, and obtains sheet material；The sheet material two sides that will be stacked overlaps respectively
Stainless steel plate, is then suppressed；The sheet material that will be suppressed is disassembled out with stainless steel plate, high so as to obtain thermosetting resin lightweight
Strong laminated material.The density of laminated material prepared by the above method is 1.1 ± 0.2g/cm3, relative to traditional material 1.6g/cm3

The performance of composite manufactured in the present embodiment is tested, as shown in table 1, table 1 is prepared by embodiment to test result
The combination property tables of data of composite.
The combination property tables of data of extremely-low density composite prepared by the embodiment of table 1
Be can be seen that by the data of table one：
The thermosetting that embodiment 1,3,4,5,6 is prepared according to inventive formulation preferred proportion and supporting process
Laminated material realizes that density is lower with traditional lightweight Materials with High Strength ratio, the more preferable performance requirement of intensity, specific strength about 0.35
＞ traditional lightweights Materials with High Strength 0.3；
Embodiment 2,7 is also to be prepared according to formula disclosed by the invention and process matched therewith method, but its hollow ball addition ratio
Example respectively lower than, beyond optimization formula ratio category of the present invention, though prepared thermosetting laminated material has density low, by force
The characteristics of spending high, but less dense is not reaching to about 0.3 with the traditional lightweight little specific strength of Materials with High Strength difference, it is higher
The requirement of intensity；
Embodiment 8~13 is the comparative example of the emphasis that the present invention discloses formula, is made comparisons with embodiment 1, and same is hollow
Microspheres weight number, but be the absence of adding auxiliary agent (suspension stabilizer, anti-phase separation agent, dispersant) accordingly, matched somebody with somebody with same
The set thermosetting laminated material prepared of process, with optimization formula disclosed by the invention than far short of what is expected in performance indications, than
Intensity about 0.26 is much smaller than optimization formula of the present invention 0.35, is far from realizing less dense, the requirement of higher intensity.It is especially real
Example 8 is applied, in the case that three kinds of auxiliary agents all lack, prepared by thermosetting laminated material is failure.
The supporting process implementing of optimization formula cooperation disclosed by the invention can realize less dense as can be seen here, more high-strength
The requirement of the thermosetting lightweight laminated material of degree, specific strength can reach 0.35, more than traditional lightweight high-strength composite material
0.3；
The explanation of above example is only intended to help and understands the method for the present invention and its core concept.It should be pointed out that right
For those skilled in the art, under the premise without departing from the principles of the invention, the present invention can also be carried out
Some improvement and modification, these are improved and modification is also fallen into the protection domain of the claims in the present invention.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention.
Various modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The scope most wide for causing.
