摘 要:針對傳統無(wú)溶劑浸漬漆中稀釋劑的毒性大、污染大等,以自制的超支化不飽和聚酯樹(shù)脂DP-1作為共稀釋劑,開(kāi)發(fā)出低揮發(fā)環(huán)保型聚酯亞胺絕緣漆;谂浞綄ζ嵋赫扯、膠凝時(shí)間、粘結強度和介電損耗等的影響規律,對絕緣漆配方進(jìn)行了優(yōu)化。結果表明,組成為m(聚酯亞胺PEI)∶m(DP-1)∶m(乙烯基甲苯VT)=100∶10∶60的配方具有較優(yōu)的綜合性能,且在180℃下的介電損耗與傳統絕緣浸漬漆相當,預計在高溫絕緣漆等領(lǐng)域具有廣闊的應用前景。 |

Abstract:In view of the toxicity and pollution occurred by the diluent in the conventional solvent-free impregnating varnish,a hyperbranched unsaturated polyester DP-1 was synthesized and used as a co-diluent,therefore a low volatile environment-friendly polyester-imide insulating paint was developed. The paint formulation was optimized on the basis of the viscosity,gelling time,cohesive strength and dielectric loss. The results demonstrated that a good paint with a broad potential application in high temperature insulating varnish should be composed of polyester-imide PEI∶DP-1∶vinyl toluene VT of 100∶10∶60. |
