Abstract
The utility model provides a polyester film and polyester fiber non-woven cloth insulating composite material which is formed by adhering polyester fiber non-woven cloth on two sides of a polyethylene terephthalate film by a bonding agent, wherein the polyester fiber non-woven cloth is prepared by taking high-strength low-extension cotton dacron fiber and thermal-binding polyester fiber as raw materials through a hot milling binding method. The product has good mechanical strength, excellent dielectric performance and better stiffness, and can be widely applied to tank insulation, interturn insulation and lining insulation in a motor and an electric appliance.
Description
Technical field
The utility model belongs to the insulating materials technical field, is specifically related to a kind of polyester film and nonwoven polyester fabric insulating composite material that is used for motor and electrical equipment.
Background technology
Along with the development of electric insulation technology, more and more higher to the requirement of insulating materials, the material that performance is single has been difficult to satisfy the requirement of high-performance electric product.A kind of heterogeneous insulating materials that the insulation component of two or more different performance, different shape is combined by composite means, compare with traditional insulating materials and to have designability, can select component material and adhesive means by the instructions for use of specific product, thereby make the different composite insulating material of temperature classification, physical and mechanical properties and electric property.
Existing insulating composite material kind is more, generally has the relatively poor deficiency that waits of mechanical strength and dielectric properties.We select for use has good absorbent properties and dipping ability, and mechanical strength height, hygroscopicity are low, the electric insulation loss is low and with insulating resin and insulating varnish the nonwoven polyester fabric of good compatibility is arranged is raw material, through repetition test repeatedly, at polyester film two sides bonded polyester fiber nonwoven fabric, make the insulating composite material of excellent performance.
Summary of the invention
The purpose of this utility model is to provide a kind of polyester film and nonwoven polyester fabric insulating composite material at existing insulating composite material mechanical strength, the relatively poor deficiency of dielectric properties.
The utility model is achieved through the following technical solutions:
Polyester film and nonwoven polyester fabric insulating composite material comprise polyester film, and the polyester film two sides is with adhesive bonded polyester fiber nonwoven fabric layer.
Described polyester film is a pet film; Described adhesive is a polyether polyols with reduced unsaturation; Described nonwoven polyester fabric layer is a raw material with cotton type polyster fibre of high-strength flatness and hot adhesion polyester fiber, makes with the hot calendering bonding method.
Insulating composite material preparation technology is: on specific complex equipment, the polyester film two sides is coated with the adhesive polyether polyols with reduced unsaturation, bonded polyester fiber nonwoven fabric is made three layers of composite flexible material through heat treatment.
Advantage of the present utility model is: have good mechanical strength, superior dielectric properties and deflection preferably, be applicable to mechanical rule insulating process, can be widely used in and do slot insulation, turn-to-turn insulation and liner insulation in motor and the electrical equipment.

The specific embodiment
Below be preferred embodiment of the present utility model, the utility model can the described content of by specification elect any mode to implement.
Specify below in conjunction with Fig. 1:
Adopt PETG through casting sheet and the biaxially oriented polyester film (2) that makes; With cotton type polyster fibre of high-strength flatness and hot adhesion polyester fiber is raw material, makes nonwoven polyester fabric layer (1) with the hot calendering bonding method; On specific complex equipment, polyester film (2) two sides is coated with the polyether polyols with reduced unsaturation adhesive, bonded polyester fiber nonwoven fabric layer (1) is made three layers of composite flexible material through heat treatment.
The every performance indications of insulating composite material of preparation are as follows:
Insulating composite material should be stored in the storehouse of the dried and clean below 40 ℃, erects directly to put, and must not or be subjected to periods of direct sunlight near burning things which may cause a fire disaster, thermal source; Need in transit crashproofly, anti-to press, moistureproof, anti-overheated, avoid mechanical damage.
Claims (3)
