Abstract
The invention provides a method for manufacturing an electric flexible polyester composite material, aiming at the problems of severe degradation of the whole performance of the flexible composite material due to poor ageing-resistant performance of polyurethane insulation adhesive, low production efficiency and the like. The invention has simple production method, and the produced product is ageing-resistant; after long term use, a motor element has high interlayer isolation, unchangeable mechanical and electrical performances under the long time action of high temperature, high humidity, corona and electric arc, ageing resistance, and prolonged service life.
Description
Technical field
The invention discloses a kind of manufacture method of electric flexible polyester composite material, belong to the insulating materials production technical field, concrete will be the production method that a kind of motor product that moves under high temperature, high humidity, power transformer product are used composite.
Background technology
Electric flexible polyester composite material is one of material of making by motor, power transformer, the manufacture method of traditional electric flexible polyester composite material is: electrician's polyester film uncoiling → two-sided immersion coating one deck polyurethane insulating adhesive → baking desolventizes → then with electrician's polyester fiber nonwoven → by 60 ℃-90 ℃ compounding machine produce continuously → compound hot pressing is two-sided electrician's polyester film, makes electric flexible polyester composite material.
There is following defective in this traditional manufacture method: the one, and the ageing-resistant performance of polyurethane insulating adhesive is relatively poor, the skin of electrician's polyester fiber nonwoven is exposed, under the effect of high temperature, high humility, corona electric arc, it is serious to cause the composite flexible material overall performance to descend; The 2nd, polyurethane insulating adhesive solid content is low, the surface layer adhesive that is coated in electrician's polyester film is thin, can't be penetrated into the skin of electrician's polyester fiber nonwoven substantially, causes at motor product to be shifted easily during at rule, particularly influence motor slot insulation and mechanical rule, production efficiency is low.
Summary of the invention
The ageing-resistant performance of the polyurethane insulating adhesive that exists at traditional electric flexible polyester composite material manufacture method is relatively poor, the skin of electrician's polyester fiber nonwoven is exposed, under the effect of high temperature, high humility, corona electric arc, it is serious to cause the composite flexible material overall performance to descend; The 2nd, polyurethane insulating adhesive solid content is low, the surface layer adhesive that is coated in electrician's polyester film is thin, can't be penetrated into the skin of electrician's polyester fiber nonwoven, cause at motor product and be shifted easily during at rule, influence motor slot insulation and mechanical rule, production efficiency is hanged down defective, the invention provides a kind of ageing-resistant electric flexible polyester composite material, after motor, power transformer use this composite, under the long term of high temperature, high humility, corona electric arc, the mechanical electric property retention is stable, increases the service life; Rule is convenient when producing motor, and steady quality is enhanced productivity.
Taked following technical scheme for realizing purpose of the present invention:
A kind of manufacture method of electric flexible polyester composite material, described manufacture method is:
1, electrician's polyester film uncoiling → two-sided immersion coating one deck polyurethane insulating adhesive → baking desolventizes → then with electrician's polyester fiber nonwoven by 60 ℃-80 ℃ compounding machine produce continuously → compound hot pressing gets semi-finished product in the two-sided → rolling of electrician's polyester film;
In the steeping vat of 2, the semi-finished product uncoiling that step 1 is prepared → heat-resisting coating glue adding compounding machine → and carry out secondary surface treatment through steeping vat, get finished product through 70 ℃ of-90 ℃ of oven dry → rollings.
Feature of the present invention is that production method is simple, after the product of production carries out secondary surface treatment, has improved the surface state and the anti-aging property of electric flexible polyester composite material significantly; After electrical equipment and electrical uses this product long-term, the layer insulation height, under the long term of high temperature, high humility, corona electric arc, the mechanical electric property retention is constant, and is ageing-resistant, prolonged the service life of electric equipment products.
Specific embodiments
Further describe technical characterictic of the present invention below in conjunction with embodiment:
Embodiment 1
A, electrician's polyester film uncoiling → two-sided immersion coating one deck polyurethane insulating adhesive → baking desolventize → then with electrician's polyester fiber nonwoven by 80 ℃ compounding machine produce continuously → compound hot pressing gets semi-finished product in the two-sided → rolling of electrician's polyester film;
B, the semi-finished product uncoiling → heat-resisting coating glue of steps A preparation added in the steeping vat of compounding machine → carry out secondary surface treatment, get finished product through 90 ℃ of oven dry → rollings through steeping vat.
The wherein preparation of the special-purpose heat-resisting coating glue of composite material surface: CYD128 type epoxy resin 100-150 weight portion, MDA 10-50 weight portion, acetone 20-70 weight portion, ethanol 10-90 weight portion, even down mixing of toluene 10-60 weight portion, normal temperature gets final product.
