Description

486500 A7 B7 V. Explanation of the invention (1) The present invention relates to an electron beam adjustment combining a flame-retardant resin material, a flame-retardant resin magnet material, and a ring magnet formed using the flame-retardant resin magnet material. Device. Today, we use a large variety of synthetic resins suitable for various purposes in our daily lives. For example, in electrical products, a large number of synthetic resin parts are used regardless of the size of the parts. However, since most synthetic resin products are organic, they have high flammability and high heat generation. Therefore, they are prone to cause major fires due to unnecessary heating. Also, for example, in a television receiving device, an electron beam adjusting device mounted on the neck of a color image tube is generally made of synthetic resin. However, the electron beam adjusting device is next to the power generating section with high heat generation. The heat of the power generation unit is liable to cause a fire. In particular, the synthetic resin magnet ring used in the electron beam adjustment device must have a flame retardant property. Therefore, the electron beam adjustment device must have high flame resistance. In recent years, the demand for the inflammability of most of the flammable synthetic resins used in daily life has increased. Therefore, in the design of products, the products are printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the back first) (Notes on the next page)

The flame retardant of the synthetic resin parts used is one of the very important items-〇 There are methods to make the flammable synthetic resin material flame retardant, for example, (1) the use of flame retardants in synthetic resin materials, (2) Synthetic resin materials are mixed with inorganic fillers, (3) blends of synthetic resin materials and flame retardant polymers, (4) copolymers of synthetic resin materials and flame retardant monomers, and the like. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 486500 V. Description of the invention (2 In addition, in order to comply with various regulations on flame resistance (such as the UL specification in the United States), the above methods The flame retardants used, inorganic fillers, flame retardant polymers, and flame retardant monomers are generally halogen-based substances. However, as the safety facilities for fire accidents have become stricter and stricter every year, these years In the future, the requirements for toxicity have increased with each passing day. Now countries in Europe and the United States have tended to stipulate that the use of current halogen-based flame retardants, inorganic fillers, flame-retardant polymers, and flame-resistant monomers is prohibited. In addition, there is also a tendency to stipulate that the use of halogen-based substances in synthetic resins is prohibited. This is because toxic substances are generated when burning halogen-based substances. For example, when burning bromine compounds, di 5-hydroxyquinoline is produced. The fact that this compound has a very bad effect on the environment is a well-known fact. Therefore, the object of the present invention is to provide a method for In addition to the flame retardancy of synthetic resins that use halogen-based substances that can cause environmental pollution, etc., no toxic substances are generated during combustion. Only non-halogen-based substances can be used to achieve flame retardancy and inexpensive flame retardant resin materials. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back first)

In addition, the present invention also provides a resin magnet material having excellent flame retardance formed by using a magnetic material in combination with the above flame-retardant resin material, and using the flame-retardant resin magnet material in, for example, a color device for television The electron beam adjustment device on the neck of the image tube and the projection type television image tube is formed with an electron beam adjustment device with excellent flame resistance. After intensive research and examination by the inventors, it was found that, for example, a large amount is required for the use of flame retardant effects, and good paper sizes such as basic resins cannot be ignored. The Chinese National Standard (CNS) A4 specification (210X297 mm) is applicable. -5 486500 A7 B7 V. Description of the invention (3) Non-halogen-based substances that make it practically unavailable at present, and as a result, a technology of resin materials having the same flame resistance as the currently used vegan-based substances can be obtained. At the same time, if the average particle diameter r of the hydrated metal oxide used can be set to 1 # m < r, the effect will be more easily obtained. In addition, a magnetic material is used in combination with the obtained flame-retardant resin material, and as a result, a resin magnet material having excellent flame resistance and mechanical strength can be obtained. In addition, using the 4-pole, 6-pole conversion magnets, and 2-pole purity adjusting magnets made of the above-mentioned flame-retardant resin magnet material, an electron beam adjusting device having excellent flame-retardant properties can be obtained.

Since the nonflammable resin material of the present invention uses only non-halogen based materials as the flame retardant, the resin constituent material itself uses only non-halogen based materials, so the possibility of generating toxic materials during combustion is extremely low. In addition, the size of the paper in the resin material applies the Chinese National Standard (CNS) A4 specification (210X297 mm). -9-(Please read the precautions on the back before ordering page 486500 A7 B7. 5. Description of the invention (7) Using magnetic materials, it can become a resin magnet material with flame resistance. At the same time, it can be a resin magnet material with strong mechanical strength. In addition, because the electron beam adjustment device using this flame resistant resin magnet material also has high flame resistance, Therefore, for example, when the device is installed on the neck of a TV color image tube, the high temperature generated by heating the adjacent power generation section can also prevent the occurrence of fire accidents. Moreover, the hydrated metal oxide contained in this flame-retardant resin material When the average particle diameter r is set to 1 wm < r < 5, a better flame retardance is obtained. If r 値 is smaller than this necessary range, the specific surface area is increased and the kneading property with the synthetic resin is reduced, making injection molding When the resin fluidity is deteriorated, the productivity will be adversely affected, and when r exceeds this necessary range, the surface activity will be hindered and the decomposition of the hydrated metal oxide will be impossible. It is not possible to impart flame retardancy to the consumer ’s cooperative organization of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back and then the page). If antimony trioxide and hydrated metal oxides can be used at the same time, multiplication can be obtained Specifically, when heated to 270 ° C, the reaction of hydrated metal oxides is first performed, and the water (H2O) generated after decomposition can prevent combustion. Then, when the temperature rises to 4 50 ° At C ~ 4 60 ° C, the reaction of hydrated metal oxides will end, and antimony trioxide will begin to melt at the same time, and this melt will diffuse to the surface of the resin. Because it has the effect of blocking air, it can prevent combustion Therefore, it can exhibit the flame retardancy when the temperature range in accordance with the UL standard is 270 ° C to 700 ° C. The present invention will be described in detail with examples and drawings below. The flame-retardant resin magnet material can be used as the magnetic ring material of the electron beam adjustment device 1 installed in the color image tube A neck 2 of the television receiver as shown in Fig. 1. • 10 486500 A7 ___ B7_ 5 、 Explanation (8) (Please read first Note on the back again, as shown in Figure 2, the electron beam adjustment device is a combination of 4-pole conversion magnets 3a, 3b, and 6-pole conversion magnets 4a, 4b, and 2-pole purity adjustment magnets 5a, 5b. These magnetic ring materials are flame-resistant resin magnet materials. As for the above-mentioned flame-resistant resin magnet materials, it refers to the materials used in combination with (D) magnetic materials in flame-resistant resin materials, and also flame-resistant resin materials. (A) Non-halogen resin composition, (B) Hydrated metal oxide and (C) Antimony trioxide as materials. (A) Non-primary resin composition mainly uses polyamine resin. The reason is Polyamine resin has excellent heat resistance and hardenability. (B) The hydrated metal oxide is mainly aluminum hydroxide or magnesium hydroxide. The average particle diameter r of the hydrated metal oxide used is preferably 1 / zm < r < 5 // m. The reason is that if r is less than 1, it will increase the specific surface area printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs and reduce the kneadability with the resin. As a result, the fluidity of the resin during injection molding will be worsened, which will affect the Productive. When r is 5 # m or more, the surface activity is inhibited, and as a result, the decomposition of the hydrated metal oxide cannot be sufficiently performed, and the flame retardancy of the resin material cannot be imparted. In addition, (C) antimony trioxide can be used alone, or (C ') zinc borate substituted for (C) antimony trioxide alone, or (C〃) antimony trioxide and zinc borate can be used instead of (C) trioxide. antimony.

When (B) hydrated metal oxide and (C) antimony trioxide are used, the weight unit (XI) of (B) hydrated metal oxide is preferably 5 for 100 weight units of (A) non-halogen-based resin composition.

Description of the invention (9) S4 0 weight unit It is more preferable to use 20 weight units and 40 weight units, and (C) the antimony trioxide weight unit X2 is preferably 0 weight units < X2 < 40 weight units, and 10 weight units and 0 weight units more good. The reason is that if the amount of antimony trioxide used exceeds 30, it is an excessive amount, which is liable to cause glow. When antimony trioxide is less than 10 weight units, it is difficult to exert its flame retardancy effect. When (B) a hydrated metal oxide and (C /) zinc borate are used, for (A) 100 weight units of a non-halogen-based resin composition, the weight unit (B) of the hydrated metal oxide X 1 is preferably 5 weight units ^ X 1 S4 0 weight units, and 30 weight units Sxi ^ 4 0 weight units are more preferred, and (C >) zinc borate weight unit X3 is preferably 0 weight units < X3S2 0 weight units It is better to use 10 weight units and 0 weight units. The reason is that if the amount of zinc borate used exceeds 20 weight units, an excessive amount is liable to cause glow, and when it is less than 10 weight units, it is difficult to exert its effect. When (B) hydrated metal oxide, (C #) antimony trioxide and zinc borate are used, (A) 100 weight unit of non-halogen resin composition, (B) weight unit of hydrated metal oxide It is preferably 5 weight units, 0 weight units, and 20 weight units, SxiS 40 weight units. Also, the weight units of (C ') antimony trioxide and zinc borate are preferably the weight portion of antimony trioxide, X2 series 2 0. Weight unit < X2 < 40 weight unit, zinc borate weight unit X3 is 0 weight unit < 10 weight unit, and the total weight of antimony trioxide weight unit X2 and zinc borate weight unit X3 is 2 0 weight units < (X2 + X3 (Please read the precautions on the back before-page order

Description of the invention (10)) < 40 weight units is better. The reason is that when (B) hydrated metal oxide and (C ") antimony trioxide and zinc borate are used, if the amount of zinc borate is excessive, it is easy to increase the glow and fire. (D) Magnetic materials are mainly pure magnetic ferromagnetic powders or aluminum-iron-nickel-cobalt magnetic alloy magnetic powders. For resin materials made of non-halogen-based resin composition, one or both of hydrated metal oxide, antimony trioxide, or zinc borate, 50 to 8 0 v ο 1% of the magnetic powder (D) has a higher content of magnetic powder It is preferably 50% ~ 20vo 1%. The reason is that if the magnetic powder is more than 50vo 1% and the resin content is small, the fluidity during kneading and molding will be deteriorated, which will reduce productivity, and when the magnetic powder is less than 20vo1%, it will be bonded to a magnet. In this case, the magnetic force is small, so it cannot sufficiently function as a conversion magnet or a magnet for purity adjustment. The flame-retardant resin magnet material of the embodiment and the method for manufacturing the same will be described below.
