Background technology
Electrical heating wire generally adopts high-melting-point, the Mo alloy of high resistivity or W alloy material manufacture, in some metal function electronic components, usually requires that and heater strip surface used is carried out insulation processing.
The Conventional processing methods that heater strip surface insulation processes is mainly electrophoresis alumina insulating layer.At present, the weak point of electrophoresis alumina insulating layer is mainly reflected in three aspects: one is firing temperature too high (generally more than 1600 DEG C), it is easy to make heater strip metal material generation recrystallization phenomenon, and toughness reduces；Two is that alumina insulating layer easily forms loose structure, and insulation resistance is not high；Three is that bond strength between aluminium oxide and tinsel is not high, the poor reliability of impact resisting vibrating.These shortcomings of electrophoresis alumina insulating layer, limit the heater strip adopting such insulating barrier use under some harsh operating conditions.
Summary of the invention
Not enough for prior art, the invention provides a kind of insulation material for heating wire, method for making and preparation and application method thereof.
A kind of insulation material for heating wire, method for making, this insulant is microcrystal glass material, and its composition and each constituent mass mark are as follows:
A kind of preparation method of heated filament insulant, it comprises the following steps:
(1) each raw material is weighed in proportion, and via batch mixer mix homogeneously；
(2) raw material of mix homogeneously is at high temperature carried out melting, then the material being fully smelted into liquid is poured into water chilling, quenches into glass particle；
(3) above-mentioned glass particle is worn into fine powder via ball mill, make insulation material for heating wire, method for making powder.
In described step (1), incorporation time is 4～12 hours.
In described step (2), smelting temperature is 1250 DEG C～1600 DEG C.
The application process of a kind of heated filament insulant, it is characterised in that comprise the steps:
(1) with the ethanol solution of silane coupler, above-mentioned insulating material powder being modulated pulping, be coated on METAL HEATING PROCESS silk surface, standing is dried；
(2) heater strip being coated with insulant is fired in high temperature furnace.
Firing temperature in described step (2) is 950 DEG C～1100 DEG C, and firing atmosphere is hydrogen.
The invention have the benefit that
The present invention adopts conventional, cheap chemical raw material, prepares insulation material for heating wire, method for making via traditional glass melting technique, and the advantage of this material is mainly reflected in the following aspects:
(1) this insulant belongs to microcrystal glass material, good insulating, and after this insulation coating is fired on heater strip surface, coating dense non-porous, insulation resistance is up to more than 1000 ohm.
(2) being firmly combined with between this insulation coating and METAL HEATING PROCESS silk, difficult drop-off, reliability is high.
(3) insulating barrier can be fired successfully at the temperature of 950 DEG C～1100 DEG C, it is to avoid too high sintering temperature makes the phenomenon of METAL HEATING PROCESS silk generation recrystallization, it is ensured that the toughness of METAL HEATING PROCESS silk is not deteriorated.

Detailed description of the invention
The invention provides a kind of insulation material for heating wire, method for making and preparation and application method thereof, below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Table 1 material proportion data table
| Raw material | SiO2 | Al(OH)3 | Na2O | ZnO | CaO | BaO | B2O3 |
| Proportioning (wt%) | 60 | 10 | 8 | 8 | 5 | 5 | 4 |
Weighing each chemical raw material by the proportioning of table 1, the purity of each raw material is analytical pure.Raw material is loaded in polyurethane mixing tank, convertible batch mixer mixes 6 hours, makes each raw material be sufficiently mixed uniformly.The raw material of mix homogeneously is loaded in silica crucible, high temperature melting furnace is heated to the high temperature of 1400 DEG C and is incubated 30min (heating rate is 5 DEG C/min), making raw material fully be smelted into liquid.Then, it is quickly poured in water by the vitreous humour of molten state chilling, quenches into glass particle.After glass particle is pulled out from water, within 24 hours, dry in atmosphere.With agate jar and ball, glass particle grinding to form on planetary high-energy ball mill fine powder, ratio of grinding media to material is 4:1, and Ball-milling Time is 12 hours.It is standby that insulant powder body after grinding crosses 300 mesh sieves.
Weigh the 5g insulating material powder prepared, with the ethanol solution (volume fraction of silane coupler is 15vol%) of silane coupler, insulating material powder is modulated pulping.The slurry modulated is evenly applied to Mo heater strip surface, stands and dry for 1 hour.Being placed in molybdenum box by coated heater strip, carry out insulating barrier and fire in high temperature furnace, firing temperature is 1100 DEG C (heating rate is 10 DEG C/min, and temperature retention time is 30min), and firing atmosphere is hydrogen.When furnace temperature naturally cools to below 100 DEG C, taking out heater strip, namely heater strip surface prepares one layer of densification, firmly insulating barrier.
Through measuring, the heater strip surface insulation resistance after firing is more than 1000 ohm.DTA analyzes display, and insulant crystallization temperature is about 835 DEG C (such as Fig. 2).It has been observed that surface of insulating layer is without hole, flawless under 80 times of optical microscopes, it is tightly combined between insulating barrier and heater strip firmly.
