TECHNICAL FIELD The present invention relates to an adhesive type synthetic rubber-based waterproofing material using waste oil and waste rubber, and more particularly to an oil-absorbing synthetic rubber-based waterproofing material which is used as automobile engine oil, industrial gear oil, hydraulic operating oil, Nonwoven fabric, PP woven fabric, HDPE film, PE foam, etc. after mixing the waste rubber powder, asphalt, tackifier, thermoplastic rubber, asphalt modifier and filler mixed with fine powder into a material having flexibility and high tackiness The present invention relates to an adhesive type synthetic rubber-based waterproofing material using waste oil and waste rubber for application as a waterproof sheet according to applications, and a manufacturing method thereof.

Generally, the conventional method of recycling waste oil includes heavy metal components such as cadmium, lead, crospite, and arsenic in waste oil, and it is difficult to burn due to a high viscosity due to its high viscosity. Since the amount of ash is large, incomplete combustion occurs, Most of the fuel oil is recycled by decompression distillation, pyrolysis at high temperature, and other purification methods, and it is impossible to apply it to products having various characteristics.

Also, the conventional method of using the waste rubber is to mix the natural rubber, the synthetic rubber, the waste tire, the EPDM rubber, and the butyl rubber by using a mechanical force mixer to give the elasticity of the rubber, There is a method of manufacturing sound insulating materials, but it is only a passive approach by primary processing.

However, recycling of such waste materials incurs additional costs to meet manufacturing facilities and quality standards. Therefore, the recycling rate is low, and most incinerators are incinerated It is a reality that it is buried and involves environmental problems such as air pollution and soil pollution.

1 is a flowchart showing a procedure of a method for manufacturing an adhesive type synthetic rubber based waterproofing material using waste oil and waste rubber according to the present invention.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

In the present invention, 15 to 25% by weight of waste oil, 5 to 10% by weight of waste rubber powder and 30 to 40% by weight of asphalt are charged and heated by heating to 170 to 190 ° C., The waterproofing material is added to the waterproof material by heating to 160 ° C to 180 ° C to prepare 100% by weight of the waterproofing material , An asphalt sheet, a nonwoven fabric, a PP woven fabric, an HDPE film, a PE foam or the like to form a waterproof sheet having flexibility and high adhesiveness.

Specifically, the adhesive type synthetic rubber based waterproofing material using the waste oil and the waste rubber according to the present invention is charged with 15 wt% to 25 wt% of waste oil, 5 wt% to 10 wt% of waste rubber powder, and 30 wt% to 40 wt% of asphalt The mixture is heated to 170 to 190 ° C and melted. 10% by weight to 20% by weight of the tackifier, 5% to 20% by weight of the asphalt modifier and 15% Followed by mixing.

At this time, it is preferable to use any of the waste oil that has been used as automobile engine oil, industrial gear oil, hydraulic operating oil, etc., which is refined by chemical purification, vacuum distillation, pyrolysis at high temperature, or other purification method.

The above-mentioned waste rubber may be used if it is a rubber product which is used in general industrial industries such as natural rubber, synthetic rubber, tire, butyl rubber, EPDM rubber, etc. and a waste rubber product which can be softened and melted by heating to 170 ° C to 190 ° C In order to shorten the melting time, it is preferable to use an emulsified waste rubber or a fine powder powder pulverized to about 200 to 400 mu m.

The asphalt is a petroleum asphalt which is solid at ordinary temperature among general asphalt products, and it is not problematic to mix by applying heat to 170 ° C to 190 ° C.

As the tackifier, one or more selected from petroleum resin, natural resin, coumarone-indene resin, terpene-phenol resin and polybutene may be used. The tackifier should be used in an amount of 10 wt% to 20 wt%, and if it is used in an amount of 10 wt% or less, the adhesive force with the surface to be adhered is weak and lifting or tackiness is difficult to maintain for a long time. If it is used in an amount exceeding 20% by weight, the viscosity of the product becomes excessively high, resulting in deterioration of workability and hardness of the product, resulting in deterioration of fluidity.

The asphalt modifier includes 5 wt% of styrene-butadiene-styrene (SBS) rubber, styrene-isoprene rubber, styrene-ethylene-butadiene- To 20% by weight.
