Definitions

• the present invention relates to a vinyl chloride resin composition modified to have physical properties useful for shoe soles, electric wire coatings, vibration insulators, power transmission belts, and the like.
• Main materials such as synthetic resin powder, clay, carbonated lime powder, clay, wood powder, etc.
• An object of the present invention is to provide a heterogeneous compound because the substance is conventionally a natural substance.
• Another object of the present invention is to provide an inexpensive, durable, recyclable
• Chloride with poor properties in various applications In the field of resins, the aim is to improve such physical properties and thereby expand the use of vinyl chloride resins.
• the present invention relates to a vinyl chloride resin composition
• a vinyl chloride resin composition comprising 100 parts by weight of a vinyl chloride resin compound (hereinafter simply referred to as "parts"), and homogeneously mixed with 1 to 10 parts of glue and gelatin by dry weight. It imparts various modifying effects such as modification of the abrasion characteristics of the vinyl chloride resin compound, improvement of adhesion to natural products, and improvement of cold resistance.
• a resin compound for shoe soles is used as the vinyl chloride resin compound, a predetermined amount of glue or gelatin is added, and the mixture is homogeneously mixed, the slip characteristics will be affected.
• the resulting molding composition for footwear is obtained.
• a resin compound for covering such as electric wires as a vinyl chloride resin compound, adding a predetermined amount of glue or gelatin, and homogenously mixing, provides a coating with excellent cold resistance.
• the composition composition is obtained. '
• a composition for a belt having non-slip properties can be obtained. Things are done.
• vibration-damping resin composition having excellent vibration damping characteristics can be obtained.
• glue or gelatin refers to the leather industry. It is supplied as a by-product, and as dried chips or pellets, jelly-like ones that are widely and generally commercially available as industrial gelatin can be used.
• jelly gelatin which is commercially available as industrial gelatin, has excellent homogeneity with the chloride chloride resin compound, can be kneaded without special treatment, and is inexpensive. It is also suitable for the purpose of modifying inexpensive vinyl chloride resin compounds.
• the amount may be selected depending on the purpose of the composition and the modification of the vinyl chloride resin compound to be blended. Generally, the modifying effect is seen from 1 part per 100 parts of the vinyl chloride resin compound. You. However, even if more than 10 parts are mixed, the improvement of the reforming effect is not seen, and the physical properties of the chlorinated vinyl resin compound itself and other properties are adversely affected. Therefore, the upper limit is 10 parts. Good.
• the —vinyl chloride resin compound— various commercially available vinyl chloride resin compounds can be used, and usually, a vinyl chloride resin compound is used. Fats are mixed with plasticizers, stabilizers, fillers, pigments, etc.
• the most common composition is a vinyl chloride resin (the degree of polymerization is selected depending on the intended use, but 1600 or more is preferred for shoe soles). It is preferable to include 100 parts, and other appropriate amounts of a foaming agent, a stabilizer, and a colorant.
• the modified resin composition according to the present invention is generally used for dissolving the raw material composition. It is produced by the process of melt-mixing, cooling, and extrusion molding, and after kneading with a mixer temperature of 70 to 120 when mixing butyl chloride resin, plasticizer, glue or gelatin solution or jelly. It is preferable to add and stabilize the mixture by adding a stabilizer and a filler, and to mix them sufficiently in a heated state so that each component can be mixed homogeneously.
• FIG. 1 is a chart showing the slip test results of a modified vinyl chloride resin composition test piece according to the present invention and a vinyl chloride resin composition comparative test piece having no glue or gelatin. It is.
• Vinyl chloride resin (high polymerization 1600 or more) 100 parts
• Plasticizer 80 parts
• Fig. 1 shows the result. From these results, the test piece according to the present invention has a high frictional resistance (maximum 57 kg) and exhibits a holding property, whereas the conventional comparative test piece has a rubbing resistance of about 30 kg. And the frictional resistance does not show any enclosing property. Therefore, it can be seen that the composition for shoe soles according to the present invention has excellent slip properties as a molding composition for footwear.

The results are as follows.
• Test piece Contains 5 parts of industrial gelatin
• the following improvement effect is achieved by uniformly dispersing and mixing the composition in the matrix of gelatin or gelatin.
• the modified compound according to the present invention has improved adhesiveness to cowhide compared to the same synthetic resin material of the related art.
• the modified compound adheres to a synthetic resin shoe sole during a normal use period without a sewing finish. It was confirmed that they did not separate. Therefore, it is excellent as a molding composition for footwear such as shoe soles, and is particularly inexpensive and practical in that the adhesiveness of renewable vinyl chloride resin is improved.
• modified composition according to the present invention has better non-slip properties than the conventional synthetic rubber-based composition, in addition to the sole of the footwear, a belt in which non-slip properties are considered important.
• Composition Useful is
