Description
Technical field
What the present invention relates to is a kind of glue and Synthesis and applications thereof, and in particular a kind of sprayed glues is applied to the technique of magnetic core spraying.
Background technology
At present, magnetic core curing technology adopts common trimeric cyanamide paint, terpolycyantoamino-formaldehyde resin etc. by the technique such as impregnation, baking, thus reach lifting magnetic core hardness and anti-seismic performance, improves the object of magnetic core product voltage, inductance performance stability.Conventional several thermoset kinds have pure epoxy, epoxy-polyester, pure polyester, vinylformic acid, urethane etc., and using method mostly is electrostatic spraying and painting invaded by fluidized-bed.The solidified glue adopted be single part epoxy resin system jointing compound substantially, under the condition of heated baking, chemical crosslink reaction occurs, just can obtain good solidification effect, and needs after hardening to fill plastic protective box or aluminium protects box and sponge pad is shockproof.Its advantage is that production technique is simple, but the baking time needed for solidification is longer, and portioned product baking time need reach 5 ~ 6 hours, in high volume production process, can consume the valuable production time in a large number, and increase human and material resources cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide the technique that a kind of sprayed glues is applied to magnetic core spraying.
The present invention is achieved by the following technical solutions, and the present invention by weight, comprises following component: 10 ~ 6 parts, the red glue of 7001A, 2.5 ~ 3.5 parts, 7001A white glue water, 2.5 ~ 3.5 parts, 7001B glue, dimethylbenzene 3 ~ 4 parts.A kind of sprayed glues preparation method, comprises the following steps:
(1) red for 7001A glue and 7001A white glue water are stirred in proportion;
(2) 7001B glue is poured in the mixing glue of step (1) and stir;
(3) dimethylbenzene is poured in the mixing glue of step (2) and stir.
The red glue of 7001A, 7001A white glue water and 7001B glue are room temperature vulcanized two-component silicone rubbers, are a kind of epoxy resin synthetic resins glue, are generally used in above LED or the encapsulation of similar electric product.The red glue of 7001A is that color is different with 7001A white glue water, and constituent class seemingly.This glue is divided into AB two kinds, and independent A glue, does not produce condensation phenomenon in atmosphere, and independent B glue also can not.But AB two kinds of glue are with after certain proportion mixing, at room temperature will in about 24 hours condensations.This epoxy resin adhesive, is applicable to electric installation.Add dimethylbenzene as organic solvent, make glue composition even, dimethylbenzene also can, as thinner, be used for diluting AB glue simultaneously.Make its viscosity just in time, uniform composition, be not easy stifled nozzle, can be used in spraying.
Described sprayed glues is applied to magnetic core spraying coating process.
Described sprayed glues is applied to magnetic core spraying coating process by one, comprises the following steps:
(1), after being dried by magnetic core, mixing glue sprays evenly on magnetic core;
(2) magnetic core sprayed is toasted 30 ~ 90 minutes at 80 DEG C ~ 120 DEG C.
Glue is sprayed on magnetic core, after the baking of certain hour, drying, reaches magnetic core solidification effect.This glue remains viscosity liquid state at normal temperatures, and under the hot environment of 80 DEG C ~ 120 DEG C, in 30 minutes ~ 90 minutes, rapidly chemical crosslink reaction can occur, and forms the wear-resisting anti-glue layer fallen of one deck at product inwall and surface.
The present invention has the following advantages compared to existing technology: the present invention overcomes glue curing in existing curing technology and toasts length consuming time, the deficiency of good solidification effect can not be obtained within a short period of time, glue formula starting material used are easy to buy, proportioning process is simple, and can in solidification spraying process, obvious shortening Procuring and the baking time needed for solidification, promote solidification effect.Further, be applied to by this glue in magnetic core spraying coating process, sprayed product does not need to protect box or the protection of other safety guards, can directly pack with large point, man power and material needed for road production process after saving magnetic core product.Can significantly improve magnetic core product solidification effect, shorten the time of solidification required for flow process, the equipment and the manpower that reduce solidification process take, and enhance productivity.
