Abstract

One or two fusion device shell body materials.Mainly solve that present ordinary epoxy resin material one side physical property is weaker (such as shock strength), and another aspect specific gravity is larger, it is more difficult to the problem of meeting the requirement of one or two fusion devices.It is characterized in that, by weight percentage, component and content are as follows: PET41% ~ 61%；Red phosphorus combustion inhibitor 3% ~ 6%；Glass fibre 15% ~ 21%；Mica 20% ~ 30%；Remaining is processing aid and stabilizer.The present invention provides one or two fusion device shell body materials, has specific gravity smaller using one or two fusion device shells made of the material, the good feature of physical property.

Description

One or two fusion device shell body materials

Technical field

The present invention relates to High-Voltage Electrical Appliances manufacture Material Fields, and in particular to one or two fusion device shell body materials.

Background technique

National grid is detected as ensureing to make " safe and reliable, fusion efficient " as technical goal using demand as guide, For the pole-mounted circuit breaker in distribution network construction transformation, spirit is exchanged according to Overall Design Standards, functional module independent, equipment The thinking of activation, the preferential telesignalling dithering for solving to face in Distribution Automation Construction, the compatibility of a second interface and scalability, Terminal increase newly line loss acquisition function the problems such as, propose pole-mounted circuit breaker should be arranged high-precision, wide scope voltage sensor and Current sensor meets the functions such as fault detection, measurement, metering and calculates the requirement of line loss.It requires to break on column to meet this Road device will configure electronic type phase current sensor, zero sequence current sensor and voltage sensor.

The vacuum circuit breaker of China's prior art has " common box type " structure, and common box type structure is by the three-phase of breaker It is placed in closed cabinet, some fills SF6 gas, some injection molding epoxy resin in case.Since SF6 gas is with greenhouse effects One of gas, therefore fill the structure pollution environment of SF6 gas；When being molded epoxy resin, present ordinary epoxy resin material Expect that one side physical property is weaker (such as shock strength), another aspect specific gravity is larger, it is more difficult to meet one or two fusion devices It is required that.

Summary of the invention

In order to overcome the shortcomings of that background technique, the present invention provide one or two fusion device shell body materials, mainly solve Present ordinary epoxy resin material one side physical property is weaker (such as shock strength), and another aspect specific gravity is larger, it is more difficult to The problem of meeting the requirement of one or two fusion devices.

The technical scheme adopted by the invention is that:

One or two fusion device shell body materials, by weight percentage, component and content are as follows:

PET 41% ~61% ；

Red phosphorus combustion inhibitor 3% ~ 6%；

Glass fibre 15% ~ 21%；

Mica 20% ~ 30%；

Remaining is processing aid and stabilizer.

The processing aid is erucyl amide, stearic one or two kinds of.

The stabilizer is one of irgasfos 168, antioxidant 1076 or two kinds.

By weight percentage, the mica content is 25%, and the content of the glass fibre is 18%, the red phosphorus flame-retardant The content of agent is 5%, and the content of the PET is 51.3%, remaining is processing aid and stabilizer.

The beneficial effects of the present invention are: the present invention provides one or two fusion device shell body materials, it is made of the material One or two fusion device shells have specific gravity it is smaller, the good feature of physical property.

Specific embodiment

The invention will be further described below: one or two fusion device shell body materials, by weight percentage, group Point and content are as follows:

PET 41% ~61% ；

Red phosphorus combustion inhibitor 3% ~ 6%；

Glass fibre 15% ~ 21%；

Mica 20% ~ 30%；

Remaining is processing aid and stabilizer.

The processing aid is erucyl amide, stearic one or two kinds of.

The stabilizer is one of irgasfos 168, antioxidant 1076 or two kinds.

Embodiment 1:

Its component and content are as follows: the mica content is 25%, and the content of the glass fibre is 18%, the red phosphorus combustion inhibitor Content is 5%, and the content of the PET is 51.3%, and the content of irgasfos 168 is 0.35% and the content of erucyl amide is 0.35%.

Physical property: tensile strength 85MPa, fracture deformation > 2%, 135 MPa of bending strength, 7822 MPa of bending modulus, 27 KJ/M2 of shock strength, specific gravity 1.68.

For low-temperature treatment (- 45 degree) after 24 hours, bending strength is 137 MPa, and bending modulus is 9300 MPa, shock strength For 17 KJ/M2.

Conventional epoxy properties of sample this compared with: bending strength be 130 Mpa, bending modulus 9923MPa, shock strength 7.96 KJ/M2, specific gravity 1.83.

For low-temperature treatment (- 45 degree) after 24 hours, bending strength is 129 Mpa, bending modulus 10560MPa, shock strength For 8.02 KJ/M2.

It can be seen that finished product made from the material, physical property has significant advantage, especially at low temperatures can On the other hand guarantee using effect well, stress is hardly damaged, and, specific gravity is also light by nearly 10%.

Embodiment 2:

Its component and content are as follows: the mica content is 20%, and the content of the glass fibre is 15%, the red phosphorus combustion inhibitor Content is 3%, and the content of the PET is 61%, remaining is irgasfos 168 and erucyl amide.

Physical property: tensile strength 83MPa, fracture deformation > 2%, 130 MPa of bending strength, 7890 MPa of bending modulus, 24 KJ/M2 of shock strength, specific gravity 1.682.

For low-temperature treatment (- 45 degree) after 24 hours, bending strength is 134 MPa, and bending modulus is 9357 MPa, shock strength For 15 KJ/M2.

Embodiment 3:

Its component and content are as follows: the mica content is 30%, and the content of the glass fibre is 21%, the red phosphorus combustion inhibitor Content is 6%, and the content of the PET is 41%, remaining is irgasfos 168 and erucyl amide.

Physical property: 82.5 MPa of tensile strength, fracture deformation > 2%, 131 MPa of bending strength, bending modulus 7886 MPa, 22 KJ/M2 of shock strength, specific gravity 1.683.
