2. Description of the Related Art Hitherto, polyester films, press boards, vulcanized fiber boards, and the like have been used as insulating materials for consumer electric appliances, vehicle electric appliances, and the like. These insulating materials are JIS C2318, C23
05 and C2315 indicate quality standards, and each material is selected according to the application. The polyester film has high insulation properties and strength, but has a drawback that it cannot be used near a heating element because of its low heat resistance temperature. On the other hand, the press board is suitable for punching workability because it is a paper base material.
If it is 0 ° C. or lower, it can be used without heat denaturation, but if it is used under higher temperature conditions, it is necessary to add a flame retardant. The vulcanized fiber board is manufactured using a cellulosic plastic,
Although it has good strength and electrical properties, it is not suitable for punching and bending, and requires the addition of a flame retardant when used under high temperature conditions, like a press board.

Hitherto, a combination of chlorinated polyolefin and antimony trioxide has been used as a flame retardant for press boards and vulcanized fiber boards. However, the use of chlorinated polyolefins, which can be a source of dioxin during incineration, has been shunned due to the growing interest in environmental issues in recent years. In addition, antimony has been pointed out as a carcinogen, has been added to the monitoring requirements of the Environment Agency's water quality standards, and its outflow to industrial wastewater during production is being regulated. The Basel Convention on the Movement of Waste, which Japan has ratified, prohibits the transfer of antimony-containing waste outside the country.

[0004] In addition, guanidine sulfamate and methylolated guanidine sulfamate are used as wallpaper flame retardants for wallpaper, but they are poor in water resistance due to water solubility and cause a decrease in electrical insulation. Although aluminum hydroxide and magnesium hydroxide are also used, they release moisture when heated, so they are not suitable for electric insulation. Sulfuric acid, phosphoric acid, and phosphorus pentoxide are also known as flame retardants, but cannot be used for paper substrates because they degrade cellulose.

Japanese Unexamined Patent Publication (Kokai) No. 52-39931 discloses a flame-retardant paper using a mixture of melamine-added ammonium polyphosphate and aluminum hydroxide as a flame retardant, but water is generated from the aluminum hydroxide during heating. Furthermore, the solubility of melamine-added ammonium polyphosphate in water is high, so that it is not suitable for use as insulating paper. JP-A-8-4
No. 9196 and JP-A-8-49197 disclose flame retardant papers using a flame retardant in which ammonium polyphosphate is coated with melamine. However, since ammonium polyphosphate deprives cellulose of water when heated, flame retardant paper is used. However, there is a disadvantage that the strength of the steel is reduced. Under the circumstances described above, a substitute for a flame retardant using a combination of a chlorinated polyolefin and antimony trioxide has been demanded, but no flame retardant has been found to replace this.

The flame retardant of the present invention is melamine phosphate particles, melamine polyphosphate particles and melamine sulfate particles, and commercially available products can be used. For example, melamine phosphate particles include T-7202 (Sanwa Chemical), melamine polyphosphate particles include MPP (Sanwa Chemical), and melamine sulfate particles include Apinone 901. These flame retardants may be used alone or in combination of two or more. These flame retardants are added so that the content (when dried) in the flame retardant insulating paper becomes 10 to 50% by weight, preferably 15 to 30% by weight. If the content is less than 10% by weight, sufficient flame retardancy cannot be obtained,
The V-0 standard of the UL standard cannot be satisfied. Also,
Even if the content is more than 50% by weight, the flame retardant effect reaches a plateau, and it is economically meaningless to mix a flame retardant which is generally expensive compared to papermaking raw materials.

In the present invention, when a higher degree of flame retardancy is required, the content (when dried) in the flame retardant insulating paper is further reduced by impregnation or coating with a glass-based flame retardant. .
You may add so that it may become 5 to 15 weight%, preferably 0.5 to 5 weight%. As the glass flame retardant, sodium borate or sodium silicate is preferable. If the content is less than 0.5% by weight, the effect of further improving the flame retardancy cannot be expected. When the content is more than 15% by weight, the flame retardant effect reaches a plateau. Further, since the glass-based flame retardant tends to have a bad influence on the electric insulation due to the influence of free sodium ions, it is not desirable to add more than 5% by weight.

The method for adding the glass-based flame retardant is not particularly limited, and is applied by a size press method, a gate roll coating method, a gravure roll coating method, or the like. At this time, a surface treatment may be carried out by appropriately blending a paper strength improver such as starch or polyvinyl alcohol, a surface sizing agent, a water-proofing agent, a dye and the like within a range that does not affect the flame retardancy and the insulating property.

According to these standards, the flame retardancy is non-flammable, HB, V-1 (extinguishes flame within 30 seconds after ignition with burner), and V-0 (extinction within 10 seconds after ignition with burner). It was ranked in order. Insulation: A dielectric breakdown test was performed according to JIS-C2111. If the test result is 5 kv / mm or more, the insulation is good.
