Abstract
The invention relates to high temperature resistant nylon. The high temperature resistant nylon comprises the following components, by weight, 45.5-90% of high temperature nylon, 8-47% of a halogen-free and alkali-free glass fiber, 4.5-18% of a carbon fiber, 2-28.5% of an alkyd resin, 2-5% of active carbon, 0.2-1.0% of a coupling agent, and 0.3-5.5% of other assistants. The high temperature resistant nylon of the invention can replace a metal raw material to produce spare and accessory parts or housings, so the parts or the housings have high physical and mechanical properties possessed by the high temperature resistant nylon, and electromagnetic shielding functions.
Description
Technical field
The present invention relates to a kind of high temperature resistance nylon.
Background technology
Shielding is exactly carrying out the isolation of metal between two area of space, with control electric field, magnetic field and hertzian wave by a zone to another regional induction and radiation.Specifically, be surrounded with the interfering source of shielding exactly, prevent that interfere with electromagnetic field is to external diffusion component, circuit, subassembly, cable or total system; With shielding receiving circuit, equipment or system are surrounded, prevent that them from receiving the influence of external electromagnetic field.
But the electroconductibility of metal and capability of electromagnetic shielding are that common high-temperature resistance plastice is not available.And at present in civil electronic electrical equipment/toy/communication/cable/many fields such as military project, all relating to needs the part with electro-magnetic screen function of heatproof at 100 to 200 degree, needs higher physical strength simultaneously.This series product market basically all has to use raw material metal production at present, and it is big to stand the process for processing difficulty, and link is many, and cost is high, a series of shortcomings that production efficiency is low or the like.These are the present invention's problem that will solve just.
The development of high-temperature nylon makes the plastic raw materials alternative metals be applied to the product that the continuous firing temperature is lower than 200 degrees centigrade and becomes a reality, and can also keep good dimensional stability.Has excellent long-term and short term thermal performance; Can tolerate infrared (IR) high temperature that reflow ovens produced that uses in the pb-free solder process, have excellent physical strength, and identical intensity and toughness is provided under wet environment; Remarkable chemical resistant properties; Dimensional stability, excellent electrical characteristic, good surface appearance.On the basis of high-temperature nylon; Through unique processing process, add related component, under the associated advantages prerequisite that keeps high-temperature nylon; Give the function of its electromagnetic shielding; Thereby at the more multi-field raw metal that substituted, make the technology of related prods be able to not receive the restriction of conditions such as raw-material processing and production/cost, be able to the development of jumping.
Summary of the invention
The objective of the invention is to effectively overcome the defective of prior art, a kind of high temperature resistance nylon of can the alternative metals starting material producing spare and accessory parts or shell is provided.
Technical scheme provided by the invention is following: high temperature resistance nylon, by following composition by weight forming high-temperature nylon: 45.5-90%; Halogen alkali-free glass fiber: 8-47%; Thomel: 4.5-18%; Synolac: 2-28.5%; Gac: 2-5%; Coupling agent: 0.2-1.0%; Other auxiliary agents: 0.3-5.5%.
The preparation method of high temperature resistance nylon of the present invention; Comprise the steps: high-temperature nylon with the aqueous solution that is made into about 30%; Add in the reaction kettle, under 40～50 ℃, normal pressure and stirring, slowly add an amount of Halogen alkali-free glass fiber, thomel, Synolac, coupling agent and other auxiliary agents.Question response finishes the back with active carbon purifying, filtration, can obtain 50% the nylon salt aqueous solution.Salt-forming reaction is thermopositive reaction, must recirculated water cooling beyond the reaction heat be removed for this reason, and is oxidized for preventing that nylon salt from contacting with air simultaneously, in production system, fills with nitrogen protection.Under vacuum state, with the nylon salt aqueous solution through evaporation, dehydration, concentrate, crystallization, drying, finally just can obtain the solid nylon salt.
Wherein, the Halogen alkali-free glass fiber has good electric insulating quality and mechanical property after reaction finishes, axial strength and modulus height; No creep; Resistance to fatigue is good, and the specific heat of thomel and electroconductibility are between nonmetal and metal, and thermal expansivity is little; Good corrosion resistance, the adding of other reagent make the high-temperature nylon that makes have more excellent performance.
The advantage of high temperature resistance nylon of the present invention: alternative raw material metal is produced spare and accessory parts or shell; At high temperature also be difficult for becoming fragile, promptly have the higher physical and mechanical properties of high temperature resistant nylon, have electro-magnetic screen function again; And production procurement is convenient; Relevant cost declines to a great extent, and has changed the high situation of selling price, has improved the competitive power of high-temperature nylon on market so greatly.
Embodiment
Below be the most preferred embodiment of high temperature resistance nylon of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of high temperature resistance nylon is provided, by following composition by weight forming high-temperature nylon: 58%; Halogen alkali-free glass fiber: 15%; Thomel: 12%; Synolac: 10%; Gac: 2%; Coupling agent: 1.5%; Other auxiliary agents: 1.5%;
High-temperature nylon with being made into about 30% the aqueous solution, is added in the reaction kettle, under 40～50 ℃, normal pressure and stirring, slowly add an amount of Halogen alkali-free glass fiber, thomel, Synolac, coupling agent and other auxiliary agents.After reaction finishes,, can obtain 50% the nylon salt aqueous solution with active carbon purifying, filtration.Salt-forming reaction is thermopositive reaction, must recirculated water cooling beyond the reaction heat be removed for this reason, and is oxidized for preventing that nylon salt from contacting with air simultaneously, in production system, fills with nitrogen protection.Under vacuum state, the nylon salt aqueous solution with 50% through evaporation, dehydration, concentrate, crystallization, drying, can obtain the solid nylon salt.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
