Abstract

PURPOSE:To obtain an inorganic powder such as magnetic or metal one, provided with organic nature with the surface hydrophobicized, by modifying the surface with a specific organophosphorus compound treatment. CONSTITUTION:The objective inorganic powder surface-modified with an treatment consisting of an organophosphorus compound of formula [R and R' are each (substituted) 1-30C alkyl, alkenyl, aryl, alkoxy, alkenoxy, or aryloxy], e.g., dibutyl phosphate. For said R or R', 4-18C alkyl will be preferable, if alkenyl or mercapto is selected, improved mechanical properties of the resin filled with said powder will also result. Enhanced fluidity and dispersibility in the processing of the above composite resin will lead, for example, to the viscosity drop in a polyvinyl chloride paste, improved impact resistance of the resin composition, etc.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel inorganic powder whose surface has been modified with an organic phosphorus compound treatment agent in order to make the surface of the inorganic powder hydrophobic and impart organic properties. The body is plastic,
The purpose of this project is to develop materials that are useful for fillers such as rubber, magnetic powders used in magnetizable plastics, and metal powders commonly used as materials for radio wave shields.

With the advancement of conventional resin composite technology and the filling of inorganic powder into resins, various drawbacks have been pointed out, such as a decrease in impact resistance and a significant decrease in melt fluidity.

In order to improve these drawbacks, many attempts have been made to hydrophobize the surface of inorganic powders and at the same time impart organic reactivity to them, and silane-based or titanate-based processing agents are commercially available as reactive camping agents.

However, these commercially available horning agents are largely limited by the hydroxyl groups on the surface of inorganic materials, and are effective against silica and silicates, but are insufficient against carbonates, sulfates, phosphates, metal oxides, and metal powders. There is a drawback that the effect is not visible.

In addition, the inorganic powder modified with an organic phosphorus compound described in JP-A No. 57-168954 uses a phosphoric acid ester compound and a phosphonic acid compound as a treatment agent, but none of them are monopolized. Because it is an ester, there is only one organic group in the molecule, so depending on the target inorganic powder, hydrophobization may not necessarily be sufficient.Also, the two 10H groups may cause powder cohesion during powder processing. In addition, the free -oH groups remaining on the powder surface are not a satisfactory treatment agent because they do not have a negative effect on the resin.As an application field for 53IJ, an inorganic powder, ferrite is added to the tonki paulownia material. Composite technology using various metals and resins has been used for a long time, but as technology advances, the modification of the surface of the inorganic powder used in these has recently become a major issue.

There are two methods for modifying the surface of these inorganic powders: wet processing and dry processing. First, to explain the wet processing method, the inorganic powder is suspended in a slurry of at least the same volume of an organic solvent, such as an alcohol or an aromatic solvent such as benzene, toluene, or xylene, and then mixed with strong stirring. c, 1 to soM weight % based on powder weight, preferably 0.5
A solution of ~20% by weight of the treatment liquid in the same solvent is added. After sufficient mixing, the mixture is heated and stirred to such an extent that the solvent is refluxed, and the cake-like powder that is precipitated and separated from the internal liquid is taken out and the solvent is thoroughly removed in an evaporator.
