Abstract
The utility model discloses a three-layer insulation composite material, which comprises a polyimide film, wherein the upper surface and the lower surface of the polyimide film are respectively compounded with inorganic-organic fiber mixed paper through an adhesive; the utility model discloses regard polyimide film as the intermediate level, both protected polyimide film not receive the alkaline medium effect, improved the combined material heat conductivity simultaneously, inhale the lacquer ability, the cost is reduced.
Description
Technical field
The utility model relate between a kind of groove that is applied to products such as heat-resisting C level (200 ℃) low voltage motor, electrical equipment, electronic transformer or, alternate or interlayer dielectic.
Background technology
Along with the fierceness day by day of low voltage motor, electrical equipment market competition, guaranteeing that under constant product quality and the reliable premise, the manufacturing cost that reduces product has great economic worth.
Between the groove of existing H (180 ℃) level or C level low voltage motor, electrical equipment, electronic transformer, alternate or interlayer dielectic generally adopts NHN--NOMEX paper Kapton composite.The heat-resisting aramid fiber NOMEX paper that the NHN composite is produced owing to employing U.S. Dupont company, excellent combination property, but cost an arm and a leg.
Summary of the invention
The utility model purpose is: a kind of three-layer insulated composite is provided; with Kapton as the intermediate layer; its upper and lower surface is passed through Heat-Resisting Adhesive composite inorganic-organic fiber mixed copy paper; both protected Kapton not to be subjected to the alkaline medium effect; improve the composite thermal conductivity simultaneously, inhaled the lacquer ability, reduced cost.
The technical solution of the utility model is: a kind of three-layer insulated composite, comprise Kapton, and the upper surface of Kapton and lower surface are compounded with inorganic-organic fiber mixed copy paper respectively by adhesive;
Above-mentioned inorganic-the organic fiber mixed copy paper by unsintered aluminosilicate ceramic fibre, E glass fibre for advocate peace a small amount of fire resistant organic fibre through mix the paper of manufacturing paper with pulp, the high temperature roll-in forms;
Above-mentioned adhesive is a kind of in heat-resisting polyurethane adhesive, epoxy adhesive or other Heat-Resisting Adhesive.
The gross thickness of this insulating composite material can be carried out combination collocation with all thickness specification of inorganic-organic fiber mixed copy paper and Kapton according to instructions for use.
The utility model advantage is:
The utility model with Kapton as the intermediate layer; its upper and lower surface is passed through Heat-Resisting Adhesive composite inorganic-organic fiber mixed copy paper; both protected Kapton not to be subjected to the alkaline medium effect; improve the composite thermal conductivity simultaneously, inhaled the lacquer ability; reduce cost, therefore can be applied to low voltage motor, electrical equipment, the electronic transformer insulation system of temperature classification H～C level more economically.
2. inorganic-organic fiber the mixed copy paper in the utility model is formed through the mixed paper of manufacturing paper with pulp, high temperature roll-in for a small amount of fire resistant organic fibre of advocating peace by unsintered aluminosilicate ceramic fibre, E glass fibre, and a spot of organic fiber has improved tensile strength, tear-proof power and the percentage elongation of paper significantly.Because inorganic-organic fiber mixed copy paper not only has and same good hear resistance, insulating properties and the tensile strength of heat-resisting aromatic polyamide paper, and being better than heat-resisting aromatic polyamide paper aspect thermal conductivity, the suction lacquer ability, price also has only 80% of heat-resisting aromatic polyamide paper.Therefore can be applied to the insulation system of H level or C level low voltage motor, electrical equipment, electronic transformer more economically.
3. Kapton of the present utility model has excellent mechanical electric performance, hot strength height.
4. of the present utility model rational in infrastructure, production technology and NHN are basic identical, and simple easy operating can be produced in enormous quantities on common compounding machine equipment, is the desirable flexible composite insulation materials of product such as H～C level low voltage motor, electrical equipment, electronic transformer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 Kapton; 2 inorganic-organic fiber mixed copy papers.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of three-layer insulated composite comprises Kapton 1, and the upper surface of Kapton 1 and lower surface are compounded with inorganic-organic fiber mixed copy paper 2 respectively by adhesive.
Above-mentioned inorganic-organic fiber mixed copy paper 2 by unsintered aluminosilicate ceramic fibre, E glass fibre for advocate peace a small amount of fire resistant organic fibre through mix the paper of manufacturing paper with pulp, the high temperature roll-in forms, a spot of organic fiber has improved tensile strength, tear-proof power and the percentage elongation of paper significantly.Above-mentioned adhesive is a kind of in heat-resisting polyurethane adhesive, epoxy adhesive or other Heat-Resisting Adhesive.
The utility model with Kapton 1 as the intermediate layer; its upper and lower surface is passed through Heat-Resisting Adhesive composite inorganic-organic fiber mixed copy paper 2; both protected Kapton 1 not to be subjected to the alkaline medium effect; improve the composite thermal conductivity simultaneously, inhaled the lacquer ability; reduce cost, therefore can be applied to low voltage motor, electrical equipment, the electronic transformer insulation system of temperature classification H～C level more economically.
Of the present utility model rational in infrastructure, production technology and DMD, NMN flexible composite insulation material are basic identical, need not reforming equipment, and simple easy operating can be produced in enormous quantities on common compounding machine equipment.
Claims (2)
1. three-layer insulated composite, it is characterized in that: comprise Kapton (1), the upper surface of Kapton (1) and lower surface are compounded with inorganic-organic fiber mixed copy paper (2) respectively by adhesive.
2. according to the described three-layer insulated composite of claim 1, it is characterized in that: described adhesive is a kind of in heat-resisting polyurethane adhesive, epoxy adhesive or other Heat-Resisting Adhesive.
