Abstract
The invention relates to the technical field of high-molecular materials and relates to a barium sulfate filled modified PTFE resinoid. The barium sulfate filled modified PTFE resinoid is prepared by low and high speed mixing, compression molding and free sintering of PTFE resinoid, barium sulfate micropowder and pigment. Teflon has excellent electric insulation, chemical stability and corrosion resistance but simultaneously also has certain disadvantages such as lack of wear resistance, creepocity and the like. The invention provides a barium sulfate filled modified PTFE resinoid which is endowed with high wear resistance, good compression resistance and cold flow creep resistance, has no influence on material machinability and frays machining cutters little.
Description
Technical field
The present invention relates to technical field of polymer materials, is the filling-modified PTFE resinoid of a kind of permanent white.
Background technology
Tetrafluoroethylene has excellent electric insulation property, chemicalstability, erosion resistance.Simultaneously, tetrafluoroethylene also has certain shortcoming: not wear-resisting, easy creep, resistance to compression difference or the like, usually through adding the inorganic powder of various high firmness; Can improve above-mentioned shortcoming; But after adding the inorganic powder of high firmness, very serious to the wearing and tearing of machine tool, be unfavorable for mechanical workout.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide and to realize high-wearing feature, good resistance to compression and creep resistance, not too influence the filling-modified PTFE resinoid of a kind of permanent white of material mechanical processibility again.
Invention realizes through following technical scheme:
The filling-modified PTFE resinoid of a kind of permanent white, it is characterized in that: its component and parts by weight are respectively:
100 parts of PTFE resinoids;
15～55 parts of permanent white micro mists;
0.1～3 part of pigment.
And the filling-modified PTFE resinoid of described a kind of permanent white is characterized in that: described PTFE resinoid is selected from one or more of PTFE suspension polymerization resin, PTFE reclaimed materials crushing resin of 15～45 microns of median sizes.
And the filling-modified PTFE resinoid of described a kind of permanent white is characterized in that: described permanent white micro mist be median size at the white powder below 40 microns, be commonly called as a huge sum of money stone flour.
And described a kind of filling-modified PTFE resinoid of pearl that floats is characterized in that: described pigment is one or more of titanium white, chrome yellow, barba hispanica, cadmium red, cadmium yellow, zinc sulfide white, carbon black, red iron oxide, yellow oxide of iron.
Characteristics of the present invention are:
1. the filling-modified PTFE resinoid of this permanent white when having good wear resistance, resistance to compression and creep-resistant property, also possesses the favorable mechanical processing characteristics, adaptable across making various PTFE machining goods.
Embodiment
The present invention further details through following examples, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
Embodiment: PTFE precision work special-purpose section
PTFE 100kg
Permanent white 54kg
Cadmium red 0.5kg
PTFE resin, permanent white, cadmium red are put into high mixer successively, and at first low speed mixing 1-2 minute, blowing after mixed at high speed 1-5 minute obtained mixed ingredients then.Mixed ingredients is joined in the mould through forcing reinforced method, use four-column hydraulic press compression moulding, under 380 ℃ temperature, freely sinter section bar into.
