Inorganic-organic fiber mixed copy paper and polyester film insulating composite material
Technical field
The utility model relate to a kind of inorganic-organic fiber mixed copy paper and polyester film insulating composite material, relate in particular between the groove of products such as a kind of F of being applied to, H level low voltage motor, electrical equipment, electronic transformer, the inorganic-organic fiber mixed copy paper and the polyester film insulating composite material of alternate or layer insulation.
Background technology
Between the groove of existing low voltage motor, electrical equipment, electronic transformer, alternate or interlayer dielectic adopts 6520 fish papers---the polyester film composite material, DMD polyester film polyester non-woven fabric composite material, NMN, NOMEX paper polyester film composite material or NHN, NOMEX paper polyimide film composite material.Though 6520, the DMD composite material is cheap, thermal endurance class is on the low side, can't satisfy F, H level electric equipment products insulating requirements.The heat-resisting aramid fiber NOMEX paper that NHN, MNM composite material are produced owing to employing U.S. Dupont company, excellent combination property, but cost an arm and a leg.
Pottery inorfil synthetic paper has outstanding high-temperature stability, and cost is also lower, but the hot strength of paper and percentage elongation are lower, and papery is soft relatively, and this has influenced being extensive use of of it to a great extent.
Summary of the invention
The utility model purpose provide a kind of inorganic-organic fiber mixed copy paper and polyester film insulating composite material, it adopts Heat-Resisting Adhesive adhering polyester film and inorganic-organic fiber mixed copy paper, makes it reduce manufacturing cost when guaranteeing excellent properties.
The technical solution of the utility model is: a kind of inorganic-organic fiber mixed copy paper and polyester film insulating composite material, described composite insulating material comprises substrate layer, attaches to the Heat-Resisting Adhesive of substrate layer one side and the polyester film bonding with the Heat-Resisting Adhesive opposite side, described substrate layer is inorganic-organic fiber mixed copy paper, and described composite insulating material is sheet or banded structure.
The further technical scheme of the utility model is: a kind of inorganic-organic fiber mixed copy paper and polyester film insulating composite material, described composite insulating material comprises substrate layer, attaches to the Heat-Resisting Adhesive of substrate layer one side and the polyester film bonding with the Heat-Resisting Adhesive opposite side, described substrate layer is inorganic-organic fiber mixed copy paper, and described composite insulating material is sheet or banded structure; Described 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; Described polyester film is a pet film; Described Heat-Resisting Adhesive is a kind of in heat-resisting polyurethane adhesive, epoxy adhesive or other Heat-Resisting Adhesive.
The utility model advantage is:
1. inorganic-organic fiber mixed copy paper that the utility model adopted is to be 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 wherein a spot of organic fiber has improved tensile strength, tear-proof power and the elongation of paper significantly.Inorganic-organic fiber mixed copy paper has and same good thermal endurance, the insulating properties of heat-resisting aramid fiber paper, and is being better than heat-resisting aramid fiber paper aspect thermal conductivity, the suction lacquer ability.
The utility model inorganic-cost of organic fiber mixed copy paper has only about 80% of heat-resisting aramid fiber paper, therefore can be applied to the insulation system of F, H level low voltage motor, electrical equipment, electronic transformer more economically.
3. of the present utility model rational in infrastructure, production technology and 6520, DMD are basic identical, and simple easy operating can be produced in enormous quantities on common compounding machine equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 inorganic-organic fiber mixed copy paper; 2 Heat-Resisting Adhesive; 3 polyester films.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 1, a kind of inorganic-organic fiber mixed copy paper and polyester film insulating composite material, described composite insulating material comprises substrate layer, attaches to the Heat-Resisting Adhesive 2 of substrate layer one side and the polyester film 3 bonding with Heat-Resisting Adhesive 2 opposite sides, described substrate layer is inorganic-organic fiber mixed copy paper 1, and described composite insulating material is sheet or banded structure.
Described inorganic-organic fiber mixed copy paper 1 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.
Described polyester film 3 is a pet film.
Described Heat-Resisting Adhesive 2 is a kind of in heat-resisting polyurethane adhesive, epoxy adhesive or other Heat-Resisting Adhesive.
Inorganic-organic fiber mixed copy paper that the utility model adopted is to be 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 wherein a spot of organic fiber has improved tensile strength, tear-proof power and the elongation of paper significantly.Inorganic-organic fiber mixed copy paper has and same good thermal endurance, the insulating properties of heat-resisting aramid fiber paper, and is being better than heat-resisting aramid fiber paper aspect thermal conductivity, the suction lacquer ability; And its cost has only about 80% of heat-resisting aramid fiber paper, therefore can be applied to the insulation system of F, H level low voltage motor, electrical equipment, electronic transformer more economically.
