Description
Technical field
The present invention relates to a kind of rotor photo-thermal dual curable trickle resins and its preparation method and application.
Background technique
As the sternness increasingly of current Environmental Protection Situation, and society constantly promote the demand of environment and health, thus just
It is required that insulating paint for motor will also have the high efficiency of the feature of environmental protection and production under the premise of meeting basic performance.Common electricity at present
Machine trickle resin is unsaturated polyester (UP) trickle resin and epoxy dipping resin.For unsaturated polyester (UP) trickle resin, deposit
It is the problem of needing two-component to mix in proportion before use, not only more demanding to technique is used, if while mixing unevenly to property
Energy is affected.In addition, it is easy to crack after the trickle resin solidification temperature high (energy consumption is high), solidification, and unsaturated polyester resin
In there are volatilizable cross-linking monomer-styrene, gaseous state styrene volatile quantity is up to 10~20% in use, give ring
Border, health and safety cause tremendous influence.For epoxy droplet dipping lacquer, equally exists two-component and asked using configuration
Topic, while there is also temperature classification low (heat distortion temperature is 110 DEG C or so), solidification temperatures need to be greater than 130 DEG C, curing time needs
Up to 1~2 hour, so that limiting it is having high-temperature behavior to require the application on material and is seriously affecting production efficiency.
It is exhausted that patent CN102020911A uses unsaturated polyester (UP) for matrix resin to report a kind of low volatilization light immersing hydrogels
Edge paint, the insulated paint can solidify under ultraviolet light and heating condition, but the insulated paint heat curing temperature is high (up to 150 DEG C), and solid
Change volatilization and is still higher than 1%.Flavine qin explores application of the ultraviolet curable insulating paint on micro machine, and [ultraviolet light solidifies
Insulated paint explorative research on micro machine, 1985 (2): 28+35-37], but there are Surface Oxygen resistances to cause table for prepared insulated paint
The tacky problem in face.Patent CN104745055A discloses the high-strength coating and its preparation side that a kind of photo-thermal dual curable is formed
The heat cure of coating is realized in method, the reaction of curing agent of the coating using hydroxy-containing resin and containing-NCO group, but contains-NCO
The activity of system is higher therefore there are problems that poor storage stability.And report that its heat curing temperature is higher than 140 DEG C according to it, to give
Coating construction brings inconvenience.Therefore develop it is a kind of with high heat resistance, low volatilization, can in low-temperature setting, stable storing, environmental protection
One-component trickle resin is an urgent demand of current rotor insulation processing industry.
