Description

Предметом изобретени   в.шетс  способ получени  компаунда дл  заливки и пропитки электротехнической аппаратуры, выполн емого па основе непредельных полиэфиров.The subject of the invention is a method of producing a compound for pouring and impregnating electrical equipment, performed on a basis of unsaturated polyesters.

Особенность предлагаемого способа , обеспечивающа  повышение фнзико-механических и диэлектрических свойств компаунда, состоит в том, что указанные полиэфиры обрабатывают диизоцианатами, а затем продукт реакции подвергают нагреванию со стиролом в присутствии 0,5-1% перекиси бензоила при 60 в течение 3-5 часов.The peculiarity of the proposed method, which provides an increase in the fnico-mechanical and dielectric properties of the compound, is that these polyesters are treated with diisocyanates, and then the reaction product is heated with styrene in the presence of 0.5-1% benzoyl peroxide at 60 for 3-5 hours .

Напри.мер, смесь полиэфира ( по весу), полученного соконденсацией касторового масла и малеинового ангидрида, с гексаметилендиизоцианатом ( по весу), нагревают до 35° в течение 15 минут, охлаждают до 20° Н прибавл ют равное по весу количество стирола, в котором растворено 0,5% перекиси бензоила и 1 % гексаметилендиизоцианата .For example, a mixture of polyester (by weight) obtained by co-condensation of castor oil and maleic anhydride, with hexamethylene diisocyanate (by weight), is heated to 35 ° for 15 minutes, cooled to 20 ° H and an equal amount of styrene is added, in which 0.5% benzoyl peroxide and 1% hexamethylene diisocyanate are dissolved.

Прп нагреванин компаунда в течение 4 часов при 60 образуетс  твердый полимер, который пе плавитс  при нагреванин и не раствор етс  в растворител х. Диэлектрические характеристики образцов по .чимеров (толниПЮЙ 0,9-1 мм) после запекани  в течение 16 часов при 120° составл ют: электрическа  прочность (в трансформаторном масле) - 27,0 кв/мм; удельное сопротивление при 20°-5,0.10 ом/см; тангенс угла диэлектрических потерь при 50 гц: при t 20°-0,0404 н при 1 80°-0,0430. Диэлектрическа  пронинаемость при 20°-3,8.After heating the compound for 4 hours at 60 a solid polymer is formed, which does not melt with the heating agent and does not dissolve in solvents. The dielectric characteristics of the samples according to .chimers (25.9–1 mm thick) after baking for 16 hours at 120 ° are: electrical strength (in transformer oil) - 27.0 kV / mm; resistivity at 20 ° -5.0.10 ohm / cm; dielectric loss tangent at 50 Hz: at t 20 ° -0.0404 n at 1 80 ° -0.0430. Dielectric constant at 20 ° -3.8.

В компаунд могут быть введены различные минеральные наполнители: пылевидный кварцевый песок, шиферна  мука, фарфорова  мука, маршалит, двуокись титана, тальк II др.Various mineral fillers can be added to the compound: powdered quartz sand, slate flour, porcelain flour, marshalite, titanium dioxide, talc II, etc.

Достоинствами компаунда, полученного по предлагаемому способу,  вл ютс : небольша  в зкость, обеспечивающа  пропитку и заливку изделий; низка  температзра отвер№ 108534- ждени , хороша  адгези  к различным материалам, хорошие диэлектрические свойства, монолитность изол ции и эластичность. Предмет изобретени . Способ получени  компаунда дл  заливки и пропитки электротехнической аппаратуры, выполн емого на - основе непредельных полиэфиров, отличают, и йен тем, что, с целью повышени  физико-механических и диэлектрических свойств компаунда , указанные полиэфиры обрабатывают диизоцианатами, а затем продукт реакции подвергают нагреванию со стиролом в присутствии 0,5-1% перекиси бензоила при 60° в течение 3-5 часов.Advantages of the compound obtained by the proposed method are: low viscosity, which provides impregnation and pouring of products; low temperature of the hole 10 108534-wait, good adhesion to various materials, good dielectric properties, solidity of insulation and elasticity. The subject matter of the invention. The method of obtaining a compound for pouring and impregnating electrical equipment, based on unsaturated polyesters, is distinguished, and yen by the fact that, in order to improve the physicomechanical and dielectric properties of the compound, these polyesters are treated with diisocyanates, and then the reaction product is heated with styrene in the presence of 0.5-1% benzoyl peroxide at 60 ° for 3-5 hours.
