It is called a fine powder and is classified into ASTMD-14457 type 3), or it is concentrated and stabilized by adding a surfactant to the latex.
- An aqueous dispersion to be produced (usually called a PTFE disperse ion) is used (for example, Japanese Patent Publication No. Hei 16-181, Japanese Unexamined Patent Publication No. — No. 5 514, Japanese Unexamined Patent Publication No. 61-26, 132, Japanese Unexamined Patent Publication No. 63-27981, Japanese Unexamined Patent Publication No. 6 1 — 1 2 7 7 5 9

- the fine powder is a powder obtained by aggregating PTFE fine particles having an average particle diameter of 0.05 to 1.0 m obtained by emulsion polymerization.
- the version is a state in which the fine particles are dispersed in water, and each of them basically contains a unit of the PTFE fine particles.
- the anti-drip function is based on the fact that the PTFE fine particles that have been emulsion-polymerized have the property of easily fibrillating.
- the PTFE fine particles when the thermoplastic resin is mixed with the fine powder or the dispersion in a molten state, the PTFE fine particles are fibrillated by the shearing force of the mixing. Then, the fibrils are dispersed in the thermoplastic resin. The fibril remains dispersed in the final molded article of thermoplastic resin. As a result, dripping during combustion is prevented.
- the flammable thermoplastic resin powder, pellet or liquid must be mixed with the PTFE before melting and mixing. It is necessary to mix it with fine powder and the above-mentioned disposable. However, the above-mentioned fine powder is easily fibrillated even at room temperature, so that the powder fluidity is poor, and there is a problem in workability when mixing. .
- the disperse ion can be easily mixed with each other if the flammable thermoplastic resin is an aqueous dispersion, but if the resin is a powder or a pellet. After the mixing, a step of removing unnecessary water and surfactant from the dispersion is required.
- the melt viscosity often increases due to excessive fibrillation.
- the load on the kneader may become too large. Due to excessive fibrillation, it may not be necessary to disperse the PTFE in the thermoplastic resin uniformly from each other. In such a case, the strand extruded from the kneading machine is cut off in the middle, and the kneading workability is significantly reduced.
- Flame retardants that make flame-retardant thermoplastics flame-retardant are essential, but the use of flame retardants generally tends to reduce the physical properties of the resin, leading to economic problems. The cost is also high.
- the PTFE fine particles are relatively expensive, but the added amount is small, so that the dispersibility of the fine particles in the resin is improved. It would be possible to reduce costs without reducing overall flame retardancy, even if the amount of flame retardants used was reduced to some extent.
- ASTMD-1 457 uses PTFE-based fine particles having a specific structure as an additive. Proposals have been made to solve the above issues at and.

- the fine particles described in the above-mentioned WO94 / 14775 and Japanese Patent Laid-Open Publication No. Hei 1-24748 are more flammable than conventional PTFE. Although the workability and dispersibility in the addition to the thermoplastic resin have been greatly improved, they still leave some unsatisfactory points.
- the fine particles described in WO94 / 14775 are added to a flammable thermoplastic resin to form a flame-retardant composition, they are introduced as a shell. In addition, the adverse effects of PVDF can be brought about. In a conventional flame retardant composition to which PTFE is added, dispersed PTFE is dried.
- PVDF has effects other than the anti-slip property, such as improving the mold releasability from the mold when molded and the friction characteristics of the molded product.
- PVDF loses such effects.
- PVDF can chemically change and cause unnecessary coloring.
- the fine particles described in Japanese Patent Application Laid-Open Nos. H 1-224748 and H5-279579 do not significantly improve workability and dispersibility. At the same time, it is inadequate with respect to the essential anti-drip properties.
