The present invention relates to a glass fiber treatment agent composition for polyolefin. BACKGROUND ART Conventionally, methods have been used to improve the mechanical properties, dimensional stability, and heat resistance of molded products by filling various thermoplastic resins with glass fibers. However, if the adhesion of the glass fiber to the resin is insufficient, a satisfactory reinforcing effect cannot be obtained. Therefore, in order to improve the adhesion with the resin, the surface of the glass fiber used is treated with an organic silane compound. However, when reinforcing polyolefin resin using glass fiber whose surface has been treated with such a compound, sufficient adhesion cannot be observed at the interface between the glass fiber and polyolefin resin because polyolefin resin is chemically inert. , a satisfactory reinforcing effect cannot be obtained. As a result of various studies by the present inventors on methods to solve this problem, we found that when polyolefin resin is filled with glass fibers treated with a composition containing a maleimide compound and an organic peroxide silane compound,
It has been found that an extremely good reinforcing effect can be obtained. The maleimide compound used in the present invention is 2,
2′-sulfonyldiphenyl (bismaleimide),
4,4'-oxydiphenyl (bismaleimide),
4,4'-methylene diphenyl (bismaleimide)
and phenylene monomaleimide. Further, the organic peroxide silane compound used in the present invention is vinyltriestershaributylperoxysilane and the like. The amount of the maleimide compound in the treatment agent composition attached to the glass fibers is 0.001 to 0.5% by weight, preferably
The amount of organic peroxide silane compound deposited is in the range of 0.01 to 0.1% by weight, preferably 0.001 to 0.5% by weight, preferably 0.01 to 0.1% by weight. Known methods for producing the glass fiber treatment agent and methods for applying the glass fiber treatment agent are sufficient. There is no problem even if a film forming agent, softener, and antistatic agent are added and used. The present invention will be specifically explained below with reference to Examples, but the present invention is not limited only to the following Examples. Example 1 The glass fiber treatment compositions of sample numbers 1, 2, and 3 of the examples shown in Table-1 and samples 1, 2, and 3 of the comparative examples were applied to glass fibers by a known method,
After drying, it was cut into 6 mm lengths. 20 parts by weight of the cut glass fibers and 80 parts by weight of an isotactic polypropylene resin having a melt index of 6 according to ASTM-D-1238 were mixed in a V-type blender and pelletized at 200 DEG C. in an extruder. This pellet was molded into a predetermined test piece using a screw injection molding machine at an injection pressure of 1000 Kg/cm 2 , a cylinder temperature of 240°C, a mold temperature of 50°C, and a cycle of 50 seconds. The tensile strength of this test piece was determined by ASTM-D-
790, flexural modulus is ASTM-D-638, impact strength (notched isot) is ASTM-D-256, heat distortion temperature is ASTM-D-648 (18.6Kg/ cm2 load)
Measured according to. The results are shown in Table-1.

[Table] From the results in Table 1, it was found that polyolefin resin molded products using glass fibers surface-treated with a maleimide compound and an organic peroxide silane compound shown in sample numbers 1, 2, or 3 of the examples of the present invention as reinforcing materials. The mechanical properties are better than those of glass fibers surface-treated with conventionally used organic silane compounds such as aminosilane, epoxysilane compounds, and peroxysilane shown in sample numbers 1, 2, and 3 of comparative examples. I understand. Example 2 Glass fiber treatment compositions of sample numbers 1 and 2 of examples and sample numbers 1, 2, 3, and 4 of comparative examples shown in Table 2 were applied to glass fibers by a known method, and dried. It was then cut to a length of 6 mm. The cut glass fibers were made into pellets under the same conditions as in Example 1, and the mechanical properties were measured after molding. Table the results.
Shown in 2.

[Table] From the results of Table 2, sample number 1 of the example of the present invention
Or, the mechanical properties of the Loliolefin resin molded product using the glass fiber surface-treated with the maleimide compound and organic peroxide silane compound shown in 2 as a reinforcing material are the same as those shown in Example 1. It can be seen that the results are better than those of glass fibers surface-treated with organic silane compounds.
