Abstract
The invention relates the modifier, which is used to make and modify high-heat polyurethane paint wire insulating paint. The modifier comprises 20-30% phenolic resin, 10-20% amido resin, 10-20% acrylic resin, 2-5% organosilicon surface active agent, and 30-60% M-and P-cresols. The method comprises the following steps: putting the phenolic resin, amidogen resin, acrylic resin and organosilicon surface active agent into M-and P-cresols, then mixing, dissolving, heating to 40-60Deg.C, stirring, and getting the mixture. The modifier is used to make high-heat polyurethane paint wire insulating paint. The method improves the continuity and pinhole property of polyurethane paint wire insulating paint, without reducing heat-proof grade of paint. The properties of the paint modified by the modifier meet international electrician IEC standard.
Description
Technical field
The present invention relates to a kind of properties-correcting agent of polyester-imide lacquer, be used to make high heat-stage non-pinhole polyesterimide enamelled wire insulating paint and modification thereof.
Background technology
High heat-stage non-pinhole polyesterimide enamelled wire insulating paint is by the imine modified high temperature-resistant wire lacquer that makes on the basis of polyester lacquer, heat-resistance index that can corresponding raising enameled wire by what of control imine group in the production is to H level and C level, but because the rigidity characteristics of imine group, make the elasticity of polyester-imide paint film compare all decline to some extent of polyester paint film with soft flexibility, directly translate into the pin hole degradation of paint film, make motor when operation under the effect of voltage, very easily produce short circuit at the pin hole place breakdown, influence the work-ing life and the safety performance of motor and electrical equipment, therefore, domestic Production of Enamel Wires producer requires more and more higher to the film integrity of enameled wire at present, the 30m line length of all being not content with the GB/T6109.11-90 requirement mostly is no more than the state of the art of 5 pinhole numbers, usually all require free of pinholes, some goes back even requires 15% free of pinholes that stretches, for adapting to customer demand, the present invention has carried out the free of pinholes modification to high heat-stage polyester-imide lacquer, has obtained satisfied effect.
Summary of the invention
The objective of the invention is to: a kind of properties-correcting agent is provided, is used for the high heat-stage non-pinhole polyesterimide enamelled wire insulating paint modification.
A further object of the present invention is: a kind of processing method is provided.
Purpose of the present invention can be achieved through the following technical solutions: high heat-stage non-pinhole polyesterimide enamelled wire insulating paint properties-correcting agent, contain the mixture of the M-and P-cresols of the amino resin of 20-30% resol, 10-20%, 10-20% acrylic resin 2-5%, organic silicon surfactant and 30-60%.
On the such scheme basis, properties-correcting agent of the present invention after allocation processing, forms stable transparent liquid oily matter by above-mentioned prescription.
Preparation method by above-mentioned high heat-stage non-pinhole polyesterimide enamelled wire insulating paint properties-correcting agent, resol, amino resin, acrylic resin and organic silicon surfactant are added in the M-and P-cresols, behind the mixed dissolution, solution is warming up to 40-60 ℃, stirs to make composite mixture.
Properties-correcting agent of the present invention is used to make the modified additive of high heat-stage non-pinhole polyesterimide enamelled wire insulating paint.
Principle of the present invention is: by add a kind of composite mixture that contains resol, amino resin, acrylic resin and organic silicon surfactant etc. in the production of polyesterimide wire enamel, after the allocating technology processing, in the temperature classification that does not reduce lacquer, can significantly improve the free of pinholes performance of polyesterimide wire enamel film.
Innovative point of the present invention and advance: the present invention is by adding a kind of resol that contains in the production of high heat-stage non-pinhole polyesterimide enamelled wire insulating paint, aminoresin, the mixture of acrylic resin and organic silicon surfactant etc., after the allocating technology processing, in the temperature classification that does not reduce lacquer, can significantly improve the continuity and the pin hole performance of polyesterimide wire enamel film, the every performance index of enameled wire that the high heat-stage non-pinhole polyesterimide enamelled wire insulating paint of handling with this compound modification coats all can satisfy International Power IEC standard-required, and pinhole number is few after stretching 15%, even free of pinholes.
