の強化材に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to reinforcing materials for synthetic resins, and in particular, it is made by mixing glass flakes and short glass fibers, so it is possible to use very high quality glass reinforced synthetic resins. The present invention relates to a synthetic resin reinforcement material that can be obtained.
［従来の技術］

製品に実用化されている。[Prior Art] Glass flakes and chopped strands have been put to practical use in various products as reinforcing materials for various synthetic resins such as thermoplastic resins and thermosetting resins.

、ミルドガラスファイバも使用されている。Glass flakes are mainly effective in improving the dimensional stability of molded products, and chopped strands are effective in improving the strength of molded products. Therefore, by using both in combination, molded products with excellent dimensional stability and mechanical properties can be obtained (Japanese Patent Publication No. 60-17223). In addition to glass flakes and chopped strands, milled glass fibers are also used as reinforcing materials for synthetic resins.

When a user uses these together, for example, when using glass flakes and chopped strands together to ensure both dimensional stability and mechanical properties of the molded product, each must be used in the kneading process with the synthetic resin. It is necessary to feed the extruder from a separate feeder.

It is characterized by being combined.
以下に本発明の詳細な説明する。The present invention will be explained in detail below.

である。On the other hand, examples of short glass fibers include chopped strands and/or milled glass fibers. There is no particular restriction on the form of the chopped strands, but if the cut length is too long, bridges will easily form in the hopper and feedability will deteriorate, so the cut length is generally 6 m.
The thickness is preferably 0.5 to 3 mm, particularly preferably 0.5 to 3 mm. The diameter of the chopped strand is preferably about 6 to 15 μm. Furthermore, as the milled glass fiber, commonly available strands or waste fibers of strands pulverized using a suitable pulverizer can be used. Although the fiber length is not necessarily constant, the fiber length of commercially available products is about 10 to 500 μm. In the present invention,
Among these, especially fiber length 20 to 300μm, fiber diameter 4
~20 μm, preferably about 6 to 13 μm is suitable.

のが好適である。There is no particular restriction on the mixing ratio of the small glass bodies made of such glass flakes and short glass fibers such as chopped strands and/or milled glass fibers, and it may vary depending on the purpose of use, the required quality of the molded product to be manufactured, etc. It will be decided as appropriate. Generally, the mixing ratio (weight ratio) of glass flakes and short glass fibers is 1=99 to 99:1, especially 20
It is preferable to mix the two in a ratio of: 80 to 80: 20.

、ノボラックエポキシタイプが好適である。Examples of the adhesive include polyvinyl acetate, polyacrylate, polyurethane, epoxy resin, and copolymers or modified products thereof. Among these, the polyurethane type may be either an aromatic or aliphatic isocyanate type, a polyester type, or a polyether type. As the epoxy type, bisphenol A type and novolac epoxy type are suitable.
これらの接着剤の使用量は、小ガラス体の重量に対して
０．１〜５重量％とするのが好ましい。The amount of these adhesives used is preferably 0.1 to 5% by weight based on the weight of the small glass body.

。If the amount of adhesive used is less than 0.1% by weight, a good bond of small glass bodies may not be obtained, and the mixture may separate, resulting in a non-uniform mixing state. Also, the amount of adhesive used is 5
If it exceeds % by weight, problems such as coloring of the molded product and inhibition of the fluidity of the resin during molding may occur.

If the particle size exceeds 6 mm, the feedability (easiness of feeding) to resin product molding equipment etc. will deteriorate, and conversely, if the particle size exceeds 6 mm,
If it is less than m, it becomes difficult to maintain a good uniform mixing state.

発明においては、このような不具合が防止される。In other words, if glass flakes, chopped strands, etc. are simply mixed, a uniform mixed state cannot be maintained due to the difference in their bulk specific gravity (generally, glass flakes have a lower bulk specific gravity than chopped strands). However, in the present invention, such problems can be prevented.
