Abstract
The invention provides a method for producing welding-assistant flame-retardant insulating paint, which is characterized in that methyl methacrylate, ethyl methacrylate, butyl methacrylate or one of butyl acrylate and vinyl silane can be selected from vinyl trimethoxy silane or one of vinyl triethoxy silane, benzoyl oxide or azobisisobutyronitrile, heated to 82-85 ℃, reacted for 1 hour, heated to 90-95 ℃, kept for 1 hour, polymerized, and polymerized to form the welding-assistant flame-retardant insulating paint, wherein the insulating paint produced by the production method has the welding-assistant property: wetting power-62 dyne, zero crossing time 1.0.3 seconds; flame retardancy: the oxygen index is more than 27.5 percent; the tin ironing temperature is 250-280 ℃, and the curing temperature and speed are 20 ℃/24 hours or 80 ℃/2 hours. The insulation resistance was 4X 1014. omega. cm.
Description
Technical field
The present invention relates to the production method of insullac, especially a kind of production method of fluxing and fire-retarding insulation lacquer.
Technical background
Existing common electrical engineering insulation paint all is to hinder the rust weldering, but the lead-in wire of the electronic devices and components after its insulation processing need go just soldering of enamelled coating on it before soldering. its burning-point is low in addition, causes fire easily.These shortcomings are brought difficulty to the welding of electron devices such as the range transformer of handling through insulation, coil lead-in wire.Though there is the weldability insullac of urethane type to come out in the market, but its tin sticky temperature is 3.75 ± 5 ℃, be higher than general tin pot and scald Xi Wendu and general electric iron welding temperature, use still inconvenient. and polyurethane paint is in protection against the tide. also undesirable aspect the insulating property.
Summary of the invention
The purpose of this invention is to provide a kind of production method that helps all good fluxing and fire-retarding insulation lacquer applied widely of soldering flame retardant resistance, electrical property, humidity resistance and insulating property.
For achieving the above object, the present invention realizes by the following method:
A kind of production method of fluxing and fire-retarding insulation lacquer; it is characterized in that to select for use one of vinyltrimethoxy silane or vinyltriethoxysilane, Oxybenzene formyl or Diisopropyl azodicarboxylate to be heated to 82 ℃-85 ℃ one of methyl methacrylate, Jia Jibingxisuanyizhi, butyl methacrylate or butyl acrylate, vinyl silanes; reacted 1 hour. be warming up to 90 ℃-95 ℃; kept 1 hour, and carried out polymerization.
The copolymer resins that makes like this has good weldability, promptly under the soldering temperature, and resin melting and do not influence scolder and metallic contact and after welding, can produce to a certain degree crosslinking reaction.Resin itself has higher insulation resistance. and less specific inductivity and dielectric loss also have good adhesive power with metal.
Embodiment
Fire retardant of the present invention is vinylformic acid dibromopropyl ester or three (2, a 3_ dibromopropyl) phosphoric acid salt. the fire retardant consumption is required to be more than 15% of amount of resin.If only use fire retardant, then flame retardant effect is relatively poor, therefore adds auxiliary flame retardant tributyl phosphate or the tritolyl phosphate of 3-5%, and then flame retardant effect significantly strengthens, and the fire retardant consumption can be reduced to 1/3rd to 1/5th of former consumption.
Thinner of the present invention is gasoline, toluene, Virahol and N-BUTYL ACETATE.
Fluxing and fire-retarding insulation lacquer of the present invention has not only solved former insullac the shortcoming that hinders soldering, and it has the weldering of helping. fire-retardant, protection against the tide and the good advantage of electrical property, when week insulating property good than insullac such as urethane, polyester, epoxies can be widely applicable for electronic devices and components welding multi pack.
Embodiment
Learn from else's experience distilled 20,35% butyl methacrylate, 13.5% methyl methacrylate, 2, (number gasoline, 9,5% toluene, 7,5% N-BUTYL ACETATE .2% Virahol and 0.05% benzoyl peroxide (initiator) are poured stainless steel cauldron or enamel reaction still container for stirring into for 7% vinyltrimethoxy silane, 2% vinyl cyanide, 38,5%I 2,. when stirring, connect thermal source, be heated to 820-85c and (note; When temperature surpasses, can produce a big quantitative response heat during oc and dash material). reacted 1 hour. be warming up to 90C-95C.Kept 1 hour.Continue reaction 3-6 hour, add which fixed (No. 3 complexing agents), I of 0,6%8 monohydroxy quinolines, 55% tritolyl phosphate and 1,75% 3 (2,3-dibromopropyl) phosphoric acid salt at last, stirring gets final product.
Above materials proportioning is a weight proportion, it can be converted into volume Shen in preparation, prepares with counting cup meter.
Because materials of the present invention, as industrial naptha. things such as reaction monomers are inflammable substance, so raw material deposit with proportioning in answer Fire Hazard Area.The motor that stirs usefulness in the reactor will be with fire proof motor to ensure safety..
