Description
Technical field
The present invention relates to a kind of fire protection flame retarding plastics, especially relate to a kind of fire protection flame retarding fluoroplastics of tetrafluoroethylene-ethylene copolymer and fire protection flame retarding switch made from this fire protection flame retarding fluoroplastics of containing.
Background technology
Making switch plastics commonly used at present is ABS material or PC material.ABS resin is vinyl cyanide (A), divinyl (B) and three kinds of monomeric multipolymers of vinylbenzene (S), and the ABS engineering plastics have extensive use, is mainly used in industry such as machinery, electric, weaving, automobile and shipbuilding, and it allows use temperature scope-40 ℃ to 80 ℃.Polycarbonate (PC) is a kind of novel thermoplastic engineering plastics, allows use temperature a wider range (100～130 ℃), transparency height (being described as " transparent metal "), nontoxic, machine-shaping convenience.The top temperature that ABS material or PC material can bear is 130 ℃, non-refractory is so the switch made from above two kinds of materials is short-circuited or electric current when causing the too high and presence of fire of switch temperature more greatly at circuit, switch can dissolve even catching fire, causes fire.
Summary of the invention
The object of the present invention is to provide a kind of novel fire protection flame retarding fluoroplastics and produce novel fire protection flame retarding switch with it.It can solve present common switch and dissolve even catching fire during too high and presence of fire in temperature, and the defective of fire hazardous has the fire protection flame retarding effect, does not burn at the naked light environment, does not produce any toxic and harmful.
Technical scheme of the present invention is to set about research from the switch manufactured materials, by starting with from aspects such as performance such as electrical specification, chemical resistance, flame retardant resistance, physical strengths, through test of many times, finally adopted tetrafluoroethylene-ethylene copolymer (PETFE is called for short F-40) as main raw, produce fluoroplastics and with this plastic applications in the production of fire protection flame retarding switch.The tetrafluoroethylene-ethylene copolymer thermotolerance is good especially, 200 ℃ of the highest continuous use working temperatures, and 180 ℃ of following non-stop runs 10 years, and electrical specification, utmost point low temperature pliability, water tolerance, chemical resistance, flame retardant resistance, performances such as physical strength are all very excellent.Owing to contain fluorine atom in the fluoroplastics molecular structure, thus the performance of a lot of excellences had, as the excellent electric insulation performance, thermotolerance, the fire line of height, outstanding oil-proofness, anti-solvent and wear resisting property, good wet fastness and resistance to low temperature etc.F-40 is electrical insulation capability and the physical strength excellent insulating material of holding concurrently.Its intensity and elongation in-200～+ 180 ℃ of scopes keeps constant substantially, and F-40 also has good cutting resistance, and creep resistance and the impact resistance under the low temperature under the high temperature all are better than tetrafluoroethylene.F-40 degree of crystallinity height, crystallization velocity is big, and adding the gentle slow cool down of chilling in man-hour does not almost have influence to its performance.The electric property excellence, the dielectric coefficient ε of F-40 is 2.6 when 1000Hz, and ε when 1MHz is above has the tendency that diminishes on the contrary when frequency, and varies with temperature very stablely, and the dielectric loss angle tangent tg δ of F-40 is 0.008 when 1000Hz.Have excellent electrical insulation capability in wide temperature and range of frequency, fluorine atom distributes symmetrically and evenly in the molecular chain, does not have the inherent dipole moment.The F-40 insulation resistance is very high, varies with temperature very for a short time, and volume specific resistance can reach 10 during room temperature
14Ω cm.Its breaking down field strength can reach 200Kv/mm thickness increase breaking down field strength and reduce gradually.The resistance toheat of F-40 is better, the F-40 plastics do not burn under material naked lights such as lighter naked light, timber ordinary combustion naked light, common plastics man-made fiber and there is no sending of any toxic and harmful, and 200 ℃ of the highest continuous use working temperatures, 180 ℃ of following non-stop runs after 10 years its elongation only drop to half of original value.Tetrafluoroethylene-ethylene copolymer is various physics, the chemical property of F-40, all satisfies the needs as the every performance of fire protection flame retarding switching material in all its bearings.In order further to improve tetrafluoroethylene-ethylene copolymer is the performance of F-40, adds a certain amount of mica powder, ferrocene (ferrocene), AL (OH)
3, Mg (OH)
2, CaCO
3Deng.The mica powder that adds plays fp and directly acts on, when mica powder is added into the %-% flameproof effect for best; The stable chemical performance of the ferrocene (ferrocene) that adds high temperature resistantly reaches 400 ℃, and when the Halogen material breakdown went out hydrogen halide, ferrocene was converted into α-Fe rapidly

3, play catalysis calcination effect, generate CO and CO
2Thereby, reduced the jet-black generation; AL (OH)
3With Mg (OH)
2AL when playing fire retardation (OH)
3Thereby in the time of 200 ℃, 300 ℃, 500 ℃, respectively there is the total heat absorption of a heat-absorbing action to play the absorbing and cooling temperature effect for 1.97KJ/g, AL (OH)
3, Mg (OH)
2With CaCO
3Play the effect of acid inhibitor and smoke elimination in the lump.CaCO
3Also play the effect of weighting agent, help reducing cost.
Technical scheme provided by the invention provides a kind of fluoroplastics of tetrafluoroethylene-ethylene copolymer, main ingredient and shared weight percent are: tetrafluoroethylene-ethylene copolymer is 75%-80%, mica powder 5%-10%, ferrocene (ferrocene) 3%-5%, AL (OH)
3, Mg (OH)
2, CaCO
3Respectively be 3%-10%.Its production technique is: F-40 and mica powder add ferrocene AL (OH) 3, Mg (OH) 2 after the abundant stirring heating of mixer, stir the back and add CaCO
3Also can add a spot of colour batch as required.
Based on the above-mentioned good fire protection flame retarding characteristic of fluoroplastics that contains tetrafluoroethylene-ethylene copolymer, the contriver has been applied in it in production of fire protection flame retarding switch, and the insulated part of this fire protection flame retarding switch is made with the above-mentioned fluoroplastics that contain tetrafluoroethylene-ethylene copolymer.
The product that this research and development technology is produced and the difference of conventional art and advantage are clearly, the electrical insulation capability excellence that contains the fire protection flame retarding fluoroplastics of tetrafluoroethylene-ethylene copolymer, fire protection flame retarding, physical strength height, and stress crack resistant is good, in light weight, cost is low, can play real fire protection flame retarding effect with the switch of its production, and do not produce any toxic and harmful, in the middle of producing, can not produce three industrial wastes, help environmental protection.
