Description of the Related Art In the case of producing a resin containing an additive such as glass powder, the dispersibility of the additive in the resin is improved or the dispersibility of the additive in the resin is improved by pulverizing the additive into fine particles. Improvement of resin characteristics by addition has been improved. The additive crushing step includes, for example, wet crushing or dry crushing. In the case of wet crushing, a step of drying the glass before adding it to the resin was necessary. Further, in the case of dry pulverization, it was difficult to reduce the particle size to, for example, the submicron order.

分散しない等の問題が生じていた。The additive powder dried after wet pulverization or the additive powder dry-pulverized is liable to agglomerate, and the agglomeration of the additive causes the addition during the molding of the resin. This caused a decrease in dispersibility of the agent. That is, when producing a temporary molded body such as a masterbatch or a compound pellet mixed with an additive, the additive is not sufficiently dispersed in the temporary molded body due to the aggregation of the additive as described above. There was a problem.

して害の少ないものとなり得る。According to such a manufacturing method, since the additive is dispersed in the liquid resin, the liquid resin is mixed with the molding resin without being dried, and the mixture is molded. Aggregation is less likely to occur, and the dispersion of the additives in the resin molded product is significantly improved. Therefore, the purpose of improving the resin properties by the addition of the additive can be effectively expressed, and conversely, the resin properties such as the strength and color of the resin change due to the aggregation of the additives, It also becomes less likely to decrease. Furthermore, since a highly volatile organic solvent is not used to disperse the additive, it may be less harmful to the human body or the environment.

If it is less than 0.5 μm, it may be difficult to manufacture or handle, and if it exceeds 1000 μm, various resin properties such as changes in strength and color of the molded resin may be deteriorated. The average particle size of the additive can be preferably 1 to 70 μm. For the measurement of the average particle diameter, for example, a laser diffraction type particle size meter can be used. In this case, in the measurement by the laser diffraction type granulometer, there is no significant difference between the diffraction behavior by the agglomerated particles of the incident laser light and the diffraction behavior by the isolated primary particles. It is not possible to distinguish between the particle size of existing particles and the particle size of secondary particles aggregated. Therefore, the average particle diameter measured by the method is a value that reflects the average particle diameter of the secondary particles including the isolated primary particles that have not caused aggregation in a broad sense.
