Description
Technical field
The invention belongs to field of compound material, relate to a kind of easily preparation, low cost, high performance advanced composite material (ACM), tool
Body relates to a kind of Gemini surface active modified glass-fiber/calcium carbonate/politef trielement composite material and preparation thereof
Method.
Background technology
Politef (PTFE) have excellence chemical stability, radiation resistance, dielectric properties, extremely low coefficient of friction and
Self lubricity, has important answering in national economy fields such as chemical industry, machinery, electronics, electrical equipment, military project, space flight, environmental protection and bridges
With.Due to the construction features of PTFE molecule, between macromole, captivation is less, and ribbon crystal is easily peeled off by lamellar, thus its performance
Go out the shortcomings such as poor mechanical property, linear expansion coefficient and load metamorphism are big.The most generally use micron order graphite, molybdenum bisuphide, copper
The inorganic particle filled modified ptfe such as powder, glass fibre overcomes these shortcomings.
Inorganic filler has the advantage such as high-modulus, easy preparation, and using its filling-modified macromolecule is that one simply effectively changes
The method of kind high molecular chemical characters.Calcium carbonate (including triple superphosphate and fine particle calcium carbonate) as the one of inorganic filler, have raw material be easy to get, price
The plurality of advantages such as cheap, good stability, color and luster are simple, nontoxic, are usually utilized to filling-modified macromolecular material, are widely used in and mould
The fields such as material, rubber, papermaking, ink, building materials, electric wire.Relative to PTFE synthetic resin, the price of calcium carbonate low to obtain
Many, add calcium carbonate to the performances such as modulus and the wearability that both can improve PTFE in PTFE, it is also possible to substantially reduce PTFE
The price of goods.Additionally, filling-modified compared to the high cost using the inorganic particulate such as molybdenum bisuphide, copper powder, the one-tenth of calcium carbonate
This most obviously will low much.Belonging to inorganic particle yet with calcium carbonate, particle surface is hydrophilic oleophobic, presents stronger pole
Property, and between PTFE matrix, adhesion is low.When calcium carbonate loading in PTFE matrix is higher, the composite of formation exists
Easily cause boundary defect during by external impacts, cause material property drastically to decline.Therefore, only calcium carbonate is carried out suitable table
Face modification could meet it has bigger loading that the mechanical strength of PTFE will not be greatly lowered again in PTFE matrix simultaneously.
Generally speaking the powder surface modification of calcium carbonate selects titanate coupling agent, aluminate coupling agent mostly, and auxiliary
Surface modification is carried out with other dispersant and auxiliary agent etc..But in view of the higher moulding process requirement of politef, mostly
The above-mentioned modifying agent of number all can not meet low cost, the effect of high efficiency modified glass fibre peacekeeping calcium carbonate, and the non-pole of some heatproof
Though property material also can play the effect of surface coating modification, but owing to the various reasons such as polarity spectrum is the biggest are extremely difficult to wrap completely
The effect covered, can make modified effect not reach most preferably, i.e. there is the modified incomplete phenomenon of degree, explores glass the most further
The modified technique of fiber-calcium carbonate-politef system, has important actual application value.
To sum up on the premise of abandoning high cost modifying agent and not selecting expensive filler, can low-cost modified inorganic filler
(calcium carbonate, glass fibre) also fills in a large number, prepares low cost, high performance glass fibre/calcium carbonate/politef three
Unit's composite seems the most urgent.
Summary of the invention
It is an object of the invention to, inorganic filler modification difficulty, loading height time property high for existing PTFE composite cost
The deficiencies such as energy difference, it is provided that a kind of Gemini surface active modified glass-fiber/calcium carbonate/politef tri compound material
Material, uses cation Gemini surfactant and paraffin to be modified glass fibre and calcium carbonate successively, makes gained modification glass
Glass fiber and calcium carbonate surface polarity change, and possess good processing fluidity, and with politef have the best
The compatibility, make gained composite material exhibits go out mechanical property and the stability of excellence, and the preparation method related to be simple, raw material

The composite of Gemini surface active modified calcium carbonate filled polytetrafluoroethylene.
The brittle failure section of the present embodiment products therefrom is scanned electronic microscope photos, and result is shown in Fig. 1～3.
CaCO is can be seen that by Fig. 1, Fig. 23Uniform particle is scattered in PTFE matrix, and particle is small-sized, distribution
Relatively wide, this is because through Gemini surface active and the CaCO of paraffin modification3Particle surface there occurs change so that its table
Surface properties changes, surface energy higher before reducing, and the reunion tendency between particle is substantially reduced, and table after modification
Face is rendered as nonpolar so that CaCO3Particle is obviously improved with the compatibility of PTFE, also increases CaCO3Particle and PTFE matrix
Interface binding power, more unmodified CaCO3It is not easy to come off.
From pattern, the most obvious effect of modification is exactly that filler grain is tightly combined with matrix, Fig. 1～3 can see
Going out, the glass fibre that draw ratio is higher is relatively big with PTFE matrix faying face, and faying face is almost without gap, and brittle failure section under high power
Upper vision glass fiber surface attachment PTFE, it can thus be appreciated that interface binding power is excellent；Section smoothness is can be seen that by Fig. 1, Fig. 2
The lowest, glass fibre, CaCO3Powder body is tightly combined with PTFE matrix, shows that modified effect is good, does not has obvious stress collection
Middle phenomenon, this is to extract activeness and quietness mechanism owing to composite strengthens the existence of phase fiber, and filler and matrix create well
Interface interaction, the composite that more unmodified filler is filled, filler grain size is relatively uniformly dispersed throughout in matrix resin, outside
Under power effect, easily cause and produce more crazing and non-unsticking, absorb more energy；Glass fibre is inorfil, hinders
The interchain sliding of PTFE macromolecular chain, is likely to become composite stress concentration point, easily sprouts micro-crack when glass fibre is more,
Tensile strength is caused to reduce.This demonstrates the good behaviour of mechanical property the most further.
