る。"Prior Art and Problems" In recent years, various plastics have been used in many fields, but
As one of the practical physical properties of plastics, it is very important that plastic products are hard to break when subjected to impact, that is, have high impact resistance. As a conventional means for improving the impact resistance of plastics, it is known to blend elastomers such as polyisobutylene, diene rubber, butyl rubber, SBR, natural rubber, etc. during the resin processing process.
この方法ではエラストマーをできるかぎり微細に樹脂中
に分散させることが好ましいが、実際上極めて困難であ
り、採用されているケースは少ない。In this method, it is preferable to disperse the elastomer in the resin as finely as possible, but it is extremely difficult in practice and is rarely used.

ある。On the other hand, plastic products do not just have to be impact resistant; they are required to meet various physical properties, among which are those that hold a certain shape and are difficult to deform even when a small amount of force is applied. This is especially necessary for molded products.

に硬さと剛性を与えることにより所望の値とされる。The physical property related to this is called the flexural modulus. Molding only plastic usually shows an unsatisfactory flexural modulus because it is too soft. In many cases, desired values are achieved by adding inorganic fillers such as mica, talc calcium carbonate, clay, and glass fiber to plastics to impart hardness and rigidity to the plastics.

の向上が求められている。Next, referring to the inherent physical properties of inorganic fillers, particles such as mica, talc, and clay have flake-like or plate-like particles, and plastics containing them are mainly due to the high aspect ratio of the particles. Although it exhibits a high flexural modulus, its impact resistance is not very good, and from the viewpoint of the physical property balance of plastics, these high aspect ratio fillers (
There is a demand for improved impact resistance when blending materials (mica, talc, clay, etc.).

They have found that the problems can be solved all at once, and have completed the present invention.

Solid elastomers such as diene rubber, butyl rubber, and 5BR1 natural rubber cannot be subjected to surface treatment. Also,
Rubber latex is in the form of a suspension, but the rubber latex in water is several μm thick, and considering the size of the inorganic filler, it is impossible to evenly cover the surface of the inorganic filler, and post-drying is required to remove moisture. is also necessary. Further, even if it is actually attempted, a satisfactory improvement in impact resistance cannot be obtained.

It was found that the intended purpose could be achieved by doing so.

い。[In the field of architecture, sealants are fillers for keeping various joints or cracks watertight or airtight, but there are also sealants that have a certain degree of strength and fix parts.6 Elastic sealants are sometimes referred to as elastic sealants or simply sealants.

4) However, for the purpose of use in the present invention, Elasto-7-7- Using only
Utilizes 100% of the bullets possessed by elastomer. Glass I・Mer 1L (IRI-) is a one-component, solvent-free type that does not require the effort of pre-mixing multiple elastomers together before use, and also requires no solvent after surface treatment of the filler. It is suitable because it does not fly away and does not require post-operation.In particular, one-component solvent-free polyurethane is one in which the elastomer curing machine uses a small amount of water as a catalyst, and this small amount of water is absorbed by the air. Water vapor or a few tenths of a percent of water on the surface of the filler is sufficient and particularly preferred.
