Abstract
The utility model discloses a three-layer structure insulation composite material, which comprises an intermediate layer polyester film, and an inorganic ceramic fiber paper and aromatic polyamide paper external layers which are respectively arranged on the upper face and the lower face of the intermediate layer polyester film, wherein heat resistance adhesive agent is used to recombine space among layers. The utility model significantly increases the tensile strength of the inorganic ceramic fiber paper, and effectively reduces the material cost of the soft insulation composite material, therefore which can be applied on heat resistance F-H-grade (155-180 DEG C) low tension motors, electrical appliances and electronic transformer insulation systems most economically, and is an idle surrogate product of NMN insulation material.
Description
Technical field
The utility model relates to a kind of three-decker insulating composite material, relate in particular to a kind of be applied to heat-resisting 155～180 ℃ of low voltage motors, electrical equipment, dry-type transformer, etc. between the groove of product, the three-decker insulating composite material of alternate or interlayer.
Background technology
Between the groove of existing F, H level low voltage motor, electrical equipment, transformer, electric tool, alternate or interlayer dielectic generally adopts NMN NOMEX paper polyester film composite material, NHN NOMEX paper polyimide film composite material.NHN, MNM composite material are because employing U.S. Dupont company is the heat-resisting aromatic polyamide fibre NOMEX paper that representative is produced, have excellent electrical insulation properties, higher thermal endurance and physical and mechanical properties, but also there is deficiency, as shows that the paint absorption capacity when varnished insulation is handled is not high; Aromatic polyamide fibre NOMEX paper costs an arm and a leg, and has increased product material cost etc.Along with the fierceness day by day of motor, electrical equipment market competition, guaranteeing that under motor, electric equipment products steady quality and the reliable premise, the manufacturing cost that reduces product has great economic worth.
Because contain 90% inorfil in forming, inorganic ceramic fibrous paper (model is CeQUIN) has outstanding heat resistance, heat resisting temperature is up to 250 ℃, and insulation life is long, and is being better than NOMEX paper aspect thermal conductivity, the suction lacquer ability.But the hot strength and the percentage elongation of CeQUIN paper are lower than NOMEX paper, and papery is soft relatively, and this has influenced being extensive use of of it to a great extent.
Prior art MNM flexible composite insulation material is to be bonded by up and down two-layer NOMEX paper and middle one deck polyester film, and thermal endurance class is F level (155 ℃).
Summary of the invention
The utility model purpose provides a kind of three-decker insulating composite material, its three layers of flexible insulation composite materials for adopting the inorganic ceramic fibrous paper to be bonded as the good aromatic polyamide paper of substrate layer and polyester film, hot strength and resistance to tearing, improved the hot strength of inorganic ceramic fibrous paper significantly, effectively reduce the material cost of flexible insulation composite material, therefore can be applied to low voltage motor, electrical equipment, the electronic transformer insulation system of thermal endurance class F～H level (155～180 ℃), be the desirable substitute products of NMN insulating material more economically.
The technical solution of the utility model is: a kind of three-decker insulating composite material, described insulating composite material comprises the intermediate layer polyester film, polyester film is respectively equipped with inorganic ceramic fibrous paper and aromatic polyamide paper skin up and down, and is compound with Heat-Resisting Adhesive between layer and the layer.
The further technical scheme of the utility model is: a kind of three-decker insulating composite material, described insulating composite material comprises the intermediate layer polyester film, polyester film is respectively equipped with inorganic ceramic fibrous paper and aromatic polyamide paper skin up and down, and is compound with Heat-Resisting Adhesive between layer and the layer; Described inorganic ceramic fibrous paper is formed through papermaking, high temperature roll-in by unsintered aluminosilicate ceramic fibre, E glass fibre, inorganic filler and high temperature resistant organic binder bond; Described polyester film is a pet film; Described aromatic polyamide paper is for to make paper pulp with Nomex fibrid and chopped strand, through not being orientated the organic synthetic fibers paper of making after the technologies such as shaping, press polish; 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:
The utility model with the inorganic ceramic fibrous paper be applied to motor, electrical apparatus insulation has the following advantages: in motor, the electrical equipment use temperature rise low, can effectively improve the continuous working period of motor, electrical equipment, increase the service life; Moisture absorption is little, has shortened the workpiece varnished insulation greatly and has handled preceding required drying time, is adapted at long-term work under the high environment of relative humidity; Inhale lacquer rate height, help improving the globality of insulation system.
2. aromatic polyamide paper and the polyester film that the utility model is good with hot strength and resistance to tearing is bonding by Heat-Resisting Adhesive and inorganic ceramic fibrous paper, form three-layer composite structure, improved the hot strength of inorganic ceramic fibrous paper significantly, therefore can be applied to low voltage motor, electrical equipment, the electronic transformer insulation system of thermal endurance class F～H level (155～180 ℃), be the desirable substitute products of NMN insulating material more economically.
3. the price of inorganic ceramic fibrous paper has only 60%～70% of aromatic polyamide paper, and such three-decker can effectively reduce the material cost of flexible insulation composite material.
4. 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.
