に、ガラス繊維を配合することは広く知られている。More specifically, in 100 parts by weight of an olefin resin, 5 to 1 glass fibers having a vinyl acetate resin, gamma-methacryloxypropyltrimethoxysilane, and vinyltristarshaributylperoxysilane in the surface layer are added.
The present invention relates to a reinforced olefin resin composition with improved flexural strength, flexural modulus, rigidity and heat distortion temperature, which is formed by blending 00 parts by weight and 5 to 150 parts by weight of an inorganic filler. Conventionally, olefin resins have been widely used in various applications because they are lightweight, inexpensive, and have excellent properties such as chemical stability. However, on the other hand, olefin resins generally have a low degree of bending strength, bending modulus, rigidity, and heat deformation temperature, so they have the disadvantage that their fields of use are inevitably limited. As one method for improving these drawbacks, it is widely known to blend glass fibers into olefin resins.

を配合することもよく知られている。However, in this method, the olefin resin and glass fibers have poor adhesion at the contact interface, so the olefin resin and glass fibers are merely mechanically mixed, and the method is based on mere mechanical bonding. Even if a reinforcing effect can be achieved, the effect of improving bending strength, bending modulus, rigidity, heat distortion temperature, etc. is not sufficient. In order to improve the adhesion between this olefin resin and glass fibers, glass fibers are treated with various chemical treatment agents, such as organic silane compounds such as vinyl silanes, acrylic silanes, amino silanes, and epoxy silanes. It is also well known that it is blended into olefin resins. However, since most olefin resins are nonpolar and chemically stable, this method hardly produces any chemical bonds between the chemical treatment agent and the olefin resin, so the improvement effect is not satisfactory. It's not a kimono. Furthermore, as another method for improving the drawbacks of these olefin resins, it is well known to incorporate inorganic fillers such as talc and calcium carbonate.

It is not possible to improve the stiffness and heat distortion temperature to a practically satisfactory degree. From this point of view, the present inventors conducted various studies to improve the bending strength, flexural modulus, rigidity, and heat distortion temperature of olefin resins. An olefin resin composition containing glass fiber and an inorganic filler having biltrimethoxysilane and vinyltriester sharybutylperoxysilane in the surface layer has excellent bending strength, bending modulus, rigidity, and heat distortion temperature. The inventors have discovered that this can be significantly improved and have arrived at the present invention.

．． 5% by weight, preferably 0.3-0.4% by weight, 0.05-0.05% by weight of vinyl triester shary butyl peroxysilane
A mixture of 0.5% by weight, preferably 0.2 to 0.3% by weight, and the balance consisting of water or an organic solvent such as toluene, is applied to glass fibers and dried to adhere. In carrying out the present invention, it is best to use the mixture as an aqueous solution. Here, the vinyl acetate resin refers to a vinyl acetate homopolymer and a vinyl acetate copolymer. These vinyl acetate resins are applied in the form of an aqueous emulsion or aqueous solution together with gamma-methacryloxypropyltrimethoxysilane and vinyltriestershaributylperoxysilane at the time of glass fiber binding. The coating amount is 0.2 to 10 (:
Fbl is preferably 0.5 to 2 (Fb is sufficient. The content of vinyl acetate resin, gamma-methacryloxypropyltrimethoxysilane, and vinyl tristar shary butylperoxysilane is 3 to 3% each of the total amount of the mixed liquid.
If the amount is less than 0.05% by weight, 0.05% by weight or less, and 0.05% by weight or less, sufficient adhesion to the glass fiber surface layer is not achieved. The adhesion between the glass fiber having tristarshaributylperoxysilane in its surface layer (hereinafter referred to as treated glass fiber) and the olefin resin is poor, and the improvement effect of the present invention is not fully exhibited.
