Abstract
The utility model provides an insulated composite forming piece of a polyester film and aromatic polyamide paper. The forming piece is formed by coating two surfaces of the polyester film with adhesive to bond the aromatic polyamide paper, wherein the polyester film is a polyethylene terephthalate film. The composite forming piece has good mechanical strength, excellent dielectrical property and good stiffness, is applicable to the insulation technology of mechanical inserted lines, and can be widely applied in motors and electrical appliances for slot insulation, interturn insulation and liner insulation.
Description
Technical field
The utility model belongs to the insulator arrangement technical field, is specifically related to a kind of polyester film and aromatic polyamide paper composite molding part that is used for motor and electrical equipment.
Background technology
The effect of insulating material is in electric equipment the different live part of electromotive force to be kept apart.Therefore, insulating material should have higher insulation resistance and compressive resistance, and good heat-resistant, thermal conductivity, moisture resistance mildew resistance and higher mechanical strength.
Along with the development of electric insulation technology, more and more higher to the requirement of insulating material, the material that performance is single has been difficult to satisfy the requirement of high-performance electric product.Insulating composite material is a kind of heterogeneous insulating material that the insulation component of two or more different performance, different shape combines by composite means, compare with traditional insulating material 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 thermal endurance class, physical and mechanical properties and electric property.
We have developed a kind of excellent insulation performance, polyester film and aromatic polyamide paper composite material that manufacturing cost is lower by repetition test in production practices.
Summary of the invention
The purpose of this utility model is to provide a kind of polyester film aromatic polyamide paper as dielectric soft composite molding part.
The utility model is achieved through the following technical solutions:
The soft composite molding part of polyester film aromatic polyamide paper is coated with the bonding aromatic polyamide paper of adhesive by laminated polyester film two sides or single face and forms.
Described laminated polyester film by PETG through casting sheet and biaxially oriented making; Adhesive is a polyether polyols with reduced unsaturation.
The soft composite molding part of polyester film aromatic polyamide paper preparation technology is: on the equipment complex of special use, on the polyester film two sides or single face be coated with adhesive bonding aromatic polyamide paper, three layers or two layers of soft composite molding part making through heat treatment.
Advantage of the present utility model is:
Have excellent mechanical performance, dielectric property and good thermal endurance, tear strength, suction lacquer ability, be reliable heat-resisting F level motor, electrical apparatus insulation material, be particularly useful for the extraordinary position of extraordinary F level motor, electrical equipment and do slot liner, turn-to-turn insulation and liner insulation; In addition, because dielectric loss of the present utility model is low, be applicable to various abominable operational environments.
