Description
Technical field
The present invention relates to Polyethersulfone Composites field, and in particular to a kind of polyether sulfone strengthens composite and its preparation side
Method.
Background technology
Polyether sulfone is, the polyethers prepared with diphenyl ether condensation by the double sulphonyl chlorodiphenyl ethers of 4,4'- under anhydrous ferric chloride catalysis
Sulfone has good combination property, and polyether sulfone high temperature resistant, corrosion-resistant, good impact resistance, compact dimensions good stability is using temperature
There is excellent mechanical performance in degree；But because ether has stronger activity, cause polyether sulfone to there is UV resistant performance poor,
Poor water resistance, the defect of high cost, therefore, reduces cost is carried out to polyether sulfone, the enhancing modification such as performance is kept to polyethers
The application of sulfone plays an important roll.Now to the fiber-reinforced modified main use glass fiber material and carbon fiber material of polyether sulfone
Material is modified treatment, and significantly, but glass fibre and carbon fiber production cost is high, environmental pollution is big is seriously limited modified effect
The application of modified poly (ether-sulfone).
Basalt fibre is a kind of emerging novel inorganic environment-friendly and green high performance fibre material, is following China's emphasis
One of four big high-performance fibers of development, it is aoxidized by silica, aluminum oxide, calcium oxide, iron oxide and titanium dioxide etc.
The basalt building stones of thing composition are prepared from after high-temperature fusion by spinning technique.Basalt continuous fiber is not only stablized
Property is good, but also with various excellent properties such as electrical insulating property, anticorrosive, flame resistant, high temperature resistant, and, basalt fibre
The discarded object that production technology is produced is few, and environmental pollution is small, directly can be transferred in ecological environment after product abandonment, without any danger
Evil, thus be a kind of qualified green, environment-friendly materials.
Therefore, glass is substituted using nontoxic, pollution-free, wide material sources, excellent performance, the basalt fiber material stablized
Glass fiber and carbon fiber strengthen polyether sulfone materials, and polyether sulfone enhancing composite is that polyether sulfone enhancing is multiple obtained from
The new direction of condensation material development.But because basalt fibre is inorganic material, and polyether sulfone is macromolecule organic material, Liang Zhexiang
Capacitive extreme difference, and basalt fibre self structure and stable performance, fiber surface is smooth, surface-active site is few, causes the Black Warrior
Rock fiber is more difficult to carry out chemical bonding and mechanical riveted with polyether sulfone materials in modifying process, i.e., basalt fibre is in polyethers
It is to be individually present in sulfone material, not good to polyether sulfone materials enhancing effect, polyether sulfone strengthens the poor-performing of composite.
The content of the invention
It is an object of the invention to overcome polyether sulfone to strengthen the defect of composite property difference, there is provided a kind of polyether sulfone enhancing
Composite and preparation method thereof；Present invention basalt fibre of the selection containing barium phosphate as reinforcing material, in coupling agent and
Be coupled with polyether sulfone in the presence of activator, it is bonded, compound, so as to obtain basalt fibre and polyether sulfone materials compatibility
More preferable polyether sulfone materials are combined, and basalt fibre more preferably, makes the composite property more excellent polyether sulfone humidification, has
Beneficial to Polyethersulfone Composites every field popularization and application.
In order to realize foregoing invention purpose, the invention provides a kind of polyether sulfone enhancing composite, including following weight
Part raw material are prepared from：1.0-15.0 parts of basalt fibre, 85.0-99.0 parts of polyether sulfone, 1-3 parts of coupling agent, 10-
25 parts of activator.
A kind of above-mentioned polyether sulfone enhancing composite, wherein it is described including short basalt fiber, it is basalt long fiber, profound
One kind in military rock cellucotton.
Wherein, barium phosphate is contained in described basalt fibre；Contain phosphate radical, phosphate radical and organic group in barium phosphate
Bonding capability it is strong, the polarity of basalt fibre and organic material can be reduced, increase and organic material compatibility；Preferably,
Described basalt fibre contains the barium phosphate of mass percent 0.1-2.0%；Most preferably, described basalt fibre contains
The barium phosphate of mass percent 0.3-0.8%.
Wherein, described coupling agent is perfluoro decyl triethoxysilane, trimethylsilyl chloride sulfonic acid and methyl-prop
One or more in alkene acryloxypropylethoxysilane trimethoxy silane.
Wherein, described activator is one or more in ethylenediamine phosphate, phosphoric acid propane diamine, prodan.
Wherein, the polyether sulfone enhancing composite, also including auxiliary agent；The auxiliary agent includes dispersant, antiseptic, anti-quiet
One or more in electric agent, fire retardant, age resister, UV resistant agent；The species of the auxiliary agent can strengthen according to polyether sulfone
Composite requires to carry out specific aim adjustment addition in different application field.
Preferably, the polyether sulfone enhancing composite, including following weight portion raw material is prepared from：5-10.0 parts
Basalt fibre 90.0-95.0 parts of polyether sulfone, 2-3 parts of coupling agent, 15-20 parts of activator.
A kind of polyether sulfone strengthens composite, and composite of the present invention is selected to contain and is easier bonded phosphorus with organic matrix
The basalt fibre of sour barium makes polyether sulfone materials and basalt as reinforcing material, and in the presence of coupling agent and activator
Double bonded structures can be formed between fiber, bonded power is strong, phase separation is not likely to produce, so that basalt fibre and polyether sulfone materials
Compatibility more preferably, basalt fiber is dramatically increased to the humidification of polyether sulfone, and the performance of resulting composite is also notable
Improve.
In order to realize foregoing invention purpose, further, the invention provides the system that a kind of polyether sulfone strengthens composite
Preparation Method, comprises the following steps：
（1）Pretreatment：Basalt fibre is carried out pre-processing to obtain treated basalt fiber with coupling agent and activator；
（2）It is compound：Treated basalt fiber and polyether sulfone materials are carried out into Combined Processing, polyether sulfone enhancing composite is obtained.
A kind of above-mentioned polyether sulfone strengthens the preparation method of composite, and the temperature pre-processed wherein in step 1 is 50-70
DEG C, temperature is higher, and reaction speed is faster, but control is more difficult, and temperature is lower, and reaction speed is slower, and reaction effect is poorer；It is preferred that
, pretreatment temperature is 55-60 DEG C.
A kind of above-mentioned polyether sulfone strengthens the preparation method of composite, and the time pre-processed wherein in step 1 is 20-
50min, process time is more long, and process time better to basalt fibre surface treatment effect but long causes to process transition,
Basalt fiber performance is remarkably decreased, and is unfavorable for being modified the enhancing of polyether sulfone；Preferably, described pretreatment time is 30-
40min。
A kind of above-mentioned polyether sulfone strengthens the preparation method of composite, and the wherein Combined Processing in step 2 refers to by work
Skill means are chemically bonded basalt fibre is pre-processed with polyether sulfone materials, basalt fibre is formed with polyether sulfone materials
Unified overall method.
A kind of polyether sulfone strengthens the preparation method of composite, and preparation method of the present invention is first with barium phosphate in certain condition
Lower principle that can be bonded with organic group, by the pretreatment of coupling agent and activator, increases basalt fibre surface-active,
Increase the compatibility with polyether sulfone, then by Combined Processing, basalt fibre is carried out composite strengthening with polyether sulfone and obtain performance
More excellent polyether sulfone enhancing composite, the inventive method is simple, convenient, and being adapted to polyether sulfone strengthens the industry of composite
