いる。(Conventional technology) Red phosphorus flame retardants have a high flame retardant effect even when added in small amounts1.
It is widely used as a flame retardant for synthetic resins because it has excellent characteristics not found in other flame retardants, such as having little effect on the physical and electrical properties of synthetic resins and not emitting harmful gases when burned.

た。In order to improve the affinity between red phosphorus and synthetic resin, the surface of red phosphorus particles is coated with a certain type of synthetic resin to improve dispersibility in the paste resin. For safer and more uniform addition of plastic resins, etc., a method is used in which a mask pellet made of a red phosphorus flame retardant and a synthetic resin is prepared in advance, and this is kneaded with a flame-retardant resin. Therefore, although mask pellets contain a high concentration of red phosphorus-based lff1 agent, until now, there have been no special legal restrictions on handling due to red phosphorus.

ている。However, as a result of the Fire Service Act being revised and ignitability tests being imposed on products containing hazardous materials, the conventional red phosphorus flame-retardant master pellets, which are based on highly combustible thermoplastic resins, are regulated as hazardous materials. The situation has become unavoidable.

There is a possibility that its usefulness may not be fully utilized.

用に寄与しようとするものである。(!!!Problem to be solved by Ming) The present invention improves the ignition risk of flame retardant resin compositions containing red phosphorus flame retardants, such as red phosphorus flame retardant master pellets, and allows storage and handling. The purpose of the present invention is to provide a composition that is safe and simple, and in which restrictions on use are eliminated or reduced, thereby contributing to the wide use of red phosphorus flame retardants.

に到達した。(Means for solving the problem) As a result of research on improving the ignitability and combustibility of red phosphorus-based flame-retardant master pellets, the inventors formed a coating layer of powdered inorganic material on the surface of the pellets using a dispersant. The inventors have discovered that by doing so, the ignitability and combustibility are generally reduced, and that there are no restrictions on handling or that the restrictions can be relaxed, and the present invention has been achieved.

リ塩化ビニル樹脂等があげられる。That is, the present invention provides a synthetic resin flame retardant composition containing a red phosphorus flame retardant, which has improved ignitability and is characterized in that a coating layer of a powdery inorganic substance is formed on the surface of the synthetic resin flame retardant composition using a dispersant. This invention relates to a combustion resin composition. Red phosphorus flame retardant master pellets usually contain several tens of percent red phosphorus flame retardant, and all highly flammable resin pellets fall under the category of hazardous materials under the Fire Service Act. Simply mixing these with powdered inorganic substances cannot improve ignitability at all, but
By treating either the resin pellet or the powdered inorganic material with a dispersant of a predetermined type, the powdered inorganic material uniformly adheres to the surface of the resin pellet, forming an ignition-inhibiting coating layer. The adhesion of the powdered inorganic material is stronger than expected, and it hardly peels off, becomes powder, or generates dust during normal handling operations, so the coating layer is extremely stable and has excellent ignitability. Synthetic resins constituting the flame retardant resin composition of the present invention that exhibit effects include polyolefin resins such as polyethylene and polypropylene, PET,
Examples include polyester resins such as PB, polyamide resins, polystyrene resins, AS, ABS, PPO, modified PPO, and polyvinyl chloride resins.

It is often used as a lubricant additive, and when carrying out the present invention, if a powdered inorganic substance of the same type as the flame-retardant resin additive is used, the effect on synthetic resins can be almost ignored. I can do it.

り好都合である。As a dispersant, any agent can be used as long as it can effectively disperse the powdered inorganic substance on the surface of the resin pellet and form a coating layer.
Considering the influence on the physical properties of synthetic resins, lubricants, antistatic agents, dispersants, surfactants, etc., which are commonly used as additives for synthetic resins, are particularly preferred as they exhibit effective dispersion action. It is more convenient to use a dispersant of the same type as the additive used, in order to avoid affecting the physical properties.

発明では、充填材やその他の添加物を含むこともできる
。The content of the red phosphorus flame retardant in the Wt smoked resin composition of the present invention can be arbitrarily adjusted depending on the composition of the raw resin pellet and the amount of attached powdered inorganic material. The flame retardant concentration of the red phosphorus-based W flame master pellets is usually 20 to 40% by weight for practical purposes, but according to the present invention, the resin pellets have extremely high ignitability, and have ignitability in almost the entire range of practical concentrations. It is possible to provide an improved flame retardant resin composition, and with resin pellets that have relatively low ignitability, the effect extends to even higher concentrations.The raw material resin pellets are synthetic resins and red phosphorus flame retardants. Although a two-component formulation is common, fillers and other additives can also be included in the present invention.

。In particular, a three-component formulation containing a filler is effective as a method for obtaining a composition with a high concentration of flame retardant. The amount of the powdered inorganic substance deposited varies depending on the composition of the raw resin pellet and the desired flame retardant content, but it is usually preferably 1 to 30 parts by weight based on 100 parts by weight of the raw resin pellet, and less than 1 part is not effective. It is not enough, and even if it exceeds 30 parts, the effect will not change.

合して用いるのが好都合である。The amount of dispersant used is usually 0.1 to 1 part by weight per 100 parts by weight of the raw resin pellet.0 The dispersant may be in either powder bundle form or liquid form, and powdered ones can be used as powdered inorganic substances. After sufficient mixing, it is convenient to mix it with the raw resin pellet, or in the case of a liquid, spread it on the raw resin pellet and then mix it with a powdered inorganic substance.
又、粉末状無機物の粒子を分散剤で予め表面処理したも
のも同様に用いることができる。Powdered inorganic particles whose surface has been previously treated with a dispersant can also be used in the same manner.

Table 3 Ingredient amounts are by weight % Table 4 (Effects) As shown in the table, the comparative example pellets corresponding to the conventional flame retardant master pellet composition are all classified as dangerous goods, but
According to the present invention, the ignitability of the products coated with a powdered inorganic substance using a dispersant is generally reduced, and the products are no longer considered dangerous.
Or it becomes a Class 2 product with improved ignitability. By adjusting the composition of raw material pellets, it is possible to obtain pellets that do not fall under the category of hazardous materials in any practical concentration range. Whether flame retardant master pellets are designated as dangerous goods, whether they are designated as Class 1, I! ! Whether the two types are classified is an extremely important issue for related industries as there are large differences in handling regulations.The present invention either does not fall under the category of dangerous goods at all, or is a red phosphorus flame retardant master with loose regulations. Pellets can be provided, and the effect in terms of storage and handling as well as safety is extremely significant, and it can contribute to the wide use of red phosphorus flame retardants, which are excellent flame retardants.

ある。Further, in carrying out the present invention, no special equipment is required;
It can be easily carried out using a simple mixing device that is commonly used, and the dispersants and powdered inorganic substances used are already used as additives for synthetic resins, and the effects on the properties of synthetic resins are extremely small. This is also an advantage of the present invention.
