Abstract
The invention discloses a heatproof high-strength insulating material for a motor. The heatproof high-strength insulating material comprises a BOPET film, aramid fiber paper and an adhesive layer. The two surfaces of the BOPET film are connected with the aramid fiber paper respectively by coating the adhesive layer; an adhesive is a mixed liquid of a high temperature resistant modified polyurethane adhesive, an epoxy adhesive and an organic silicone adhesive; and the adhesive contains inorganic filling materials and glass fibers. According to the invention, a mixed type adhesive is adopted, and at the same time, the inorganic filling materials and the glass fibers are innovatively added into the mixed adhesive so that the heat resistance performance and the mechanical strength of the adhesive layer is further improved, no sizing material overflows, the prepared insulation material is of excellent heat resistance performance, electrical insulating performance and glue-line intensity, the insulation heat resistance is good, and the wearing property is good.
Description
Technical field
The present invention relates to insulating material technical field, particularly relate to a kind of motor heat-resistance high-strength insulating material.
Background technology
Motor adopts polyester film and Nomex paper to cohere and be composited with polyurethane adhesive with insulating material conventionally, this insulating material is combined the excellent heat resistance of Nomex paper effectively with the superior mechanical electric property of poly-vinegar film, expand the scope of application of individual event material, reduced the use cost of insulating material simultaneously.But because the resistance to elevated temperatures of its adhesive for polyurethane using is poor, in temperature, there will be thermal degradation during higher than 200 ℃, thereby easily there is the physical chemistry breakoff phenomenons such as foaming, layering while using in this insulating material in high temperature, limited its scope of application; In addition, the glue-line intensity of this insulating material is lower, is prone to the situations such as glue of overflowing of coming unstuck after use, not only affects serviceability, and pollutes use equipment.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of motor heat-resistance high-strength insulating material, can, when meeting electrical insulation properties, improve heat resistance and the mechanical strength of glue-line, thereby improve the serviceability of insulating material.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of motor heat-resistance high-strength insulating material is provided, comprise: BOPET film, aromatic polyamide paper and adhesive layer, the two sides of described BOPET film is connected with aromatic polyamide paper by coating adhesive adhensive layer respectively; Described adhesive is the mixed liquor of heat resist modification adhesive for polyurethane, epoxy adhesive and the agent of organosilicon gluing; In described adhesive, contain inorganic filler and glass fibre.
In a preferred embodiment of the present invention, in described adhesive, the mixed proportion of heat resist modification adhesive for polyurethane, epoxy adhesive and the agent of organosilicon gluing is 3:2:1.
In a preferred embodiment of the present invention, described inorganic filler is nanometer potter's clay or nano silicon.
In a preferred embodiment of the present invention, the addition of described inorganic filler is 30% of adhesive total weight.
In a preferred embodiment of the present invention, the length of described glass fibre is 20 μ m～0.5mm.
In a preferred embodiment of the present invention, the addition of described glass fibre is 10% of adhesive total weight.
The invention has the beneficial effects as follows: a kind of motor of the present invention heat-resistance high-strength insulating material adopts mixed type adhesive, creatively in mixing adhesive, add inorganic filler and glass simultaneously, heat resistance and the mechanical strength of adhesive layer have further been improved, without sizing material, overflow, prepared insulating material has excellent heat resistance, electrical insulation properties and glue-line intensity, insulation heat resistance is good, and durability is good.
