本発明は、新規なゴムアスファルトの製造方法に関し、

ファルトの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a novel method for producing rubber asphalt,
More specifically, the present invention relates to a new method for producing rubber asphalt using recycled butyl rubber.

つつ溶解することが行われて来た。(Prior art) Conventionally, in order to produce rubber asphalt using butyl recycled rubber, the rubber was masticated with a mixing roll and then added to molten asphalt, and the mixture was dissolved by continuous heating and stirring for an extremely long time, or by kneading. Conventionally, a master patch of rubber and asphalt is prepared in advance using a roll or a pressure kneader, and the master patch is added to molten asphalt and dissolved while stirring.

なり作業上好ましくない。(Problems to be Solved by the Invention) However, butyl recycled rubber is difficult to dissolve in asphalt, and in some cases it takes a very long time to completely dissolve the rubber and obtain a uniform rubber asphalt.
It may take more than time. In addition, the method of making a masterbatch using rubber and asphalt can shorten the time required for dissolution to some extent, but the masterbatch becomes sticky and stringy, making it extremely difficult to handle, which is undesirable in terms of work.
（問題点を解決するための手段）
本発明は、これらの欠点を解消し、かつ取扱いが簡便で
容易にゴムアスファルトを製造することができる方法を
提供することを目的としてなされたものである。(Means for Solving the Problems) The present invention has been made for the purpose of solving these drawbacks and providing a method for producing rubber asphalt that is simple and easy to handle.

投入し、撹拌しながら溶解するものである。That is, for 100 parts by weight of butyl recycled rubber, a mixture of 7 or more hydrocarbon compounds that are soluble in asphalt and have a melting point of 60 to /λo'c.
After adding 0 to 700 parts by weight and mixing uniformly, the rubber mixture is chipped into molten asphalt and dissolved while stirring.

た耐老化性を有するので、それの再生ゴムも安価なうえ
、すぐｎた性能を有しているので多用されている。Butyl recycled rubber is usually produced by collecting automobile tubes, washing them, pulverizing them in a crusher, rolling them through a grinder, and treating them in a desulfurizer at a temperature of about 2°C for 5 hours. After that, it is kneaded in a Banbury mixer and then kneaded with rolls several times. As is known, butyl rubber has a very low degree of unsaturation and therefore has excellent aging resistance, and recycled rubber thereof is also inexpensive and has excellent performance, so it is widely used.

れる。The hydrocarbon compound used in the invention is one that is soluble in asphalt and has a melting point of 60 to 20'C.
, preferably 70 to 700°C, such as fatty acids, fatty acid esters, fatty acid anhydrides, other fatty acid derivatives, and some natural resins and synthetic resins.

えない。The blending ratio of the butyl recycled rubber and the hydrocarbon compound is 1 part by weight of the butyl recycled rubber and 1 part by weight of the butyl recycled rubber.
0 to 100 parts by weight, preferably 35 to AO parts by weight. To mix these, you can first masticate them with a kneading roll that has been cooled by passing water through them, then add the hydrocarbon compound and mix. Alternatively, you can mix the rubber with the hydrocarbon compound and knead it by rolling it from the beginning. There is no problem.
このようにして得られたゴム混合物は、ゴムの粒子と粒
子の間に炭化水素化合物が充分入り込んだ状態になって
いると推定されるが、炭化水素化合物の配合量が７０重
量部以下であると、ゴムの粒子間に入り込む炭化水素化
合物の量が不足し、このようなゴム混合物を溶融アスフ
ァルトに加えて溶解しても、均一なゴムアスファルトを
得るには時間がながくかかり過ぎる。一方炭化水素化合
物の配合量が１００重量部を超えると、ゴムに対する添
加量が過剰となり、かえって良好なゴム混合物が得られ
ない。It is estimated that the rubber mixture thus obtained is in a state where the hydrocarbon compound is sufficiently entrapped between the rubber particles, but the amount of the hydrocarbon compound blended is 70 parts by weight or less. This results in an insufficient amount of hydrocarbon compounds intercalating between the rubber particles, and even if such a rubber mixture is added to molten asphalt and dissolved, it takes too long to obtain a uniform rubber asphalt. On the other hand, if the amount of the hydrocarbon compound exceeds 100 parts by weight, the amount added to the rubber will be excessive and a good rubber mixture will not be obtained.
前記の適正な配合がなされたゴム混合物をｌコｏ゛Ｃ以
上の溶融アスファルト中に投入し撹拌すると、先づゴム
の粒子と粒子の間に介在する炭化水素化合物が、ただち
に溶融して液状となり同時にアスファルトに溶解する。When the above-mentioned properly formulated rubber mixture is poured into molten asphalt with a temperature of 1 °C or higher and stirred, the hydrocarbon compounds interposed between the rubber particles immediately melt and become liquid. At the same time, it dissolves in asphalt.
それ故、ゴム粒子間に介在する炭化水素化合物がアスフ
ァルトと置きかわりゴムの溶解が非常に促進される結果
になる。つまり、ゴム粒子とアスファルトとの接触が迅
速に行なわ汎、ゴムの溶解がきわめて容易になるもので
ある。Therefore, the hydrocarbon compound interposed between the rubber particles replaces the asphalt, resulting in greatly accelerated dissolution of the rubber. In other words, the rubber particles come into contact with the asphalt quickly, and the rubber becomes extremely easy to dissolve.
融点がＡ Ｏ’Ｏ以下の炭化水素化合物を配合した場合

昇するのでペタつきが生じ、ロール表面から素材を剥が

０°Ｃ以上のものでは、アスファルトに溶解しにクク、
特に低温のアスファルトに対しては溶解しにくり、従っ
てゴムの溶解を非常に遅らせる結果となる。If a hydrocarbon compound with a melting point of A O'O or lower is blended, the temperature of the material will inevitably rise during roll kneading, causing stickiness and making it difficult to peel off the material from the roll surface, resulting in poor workability. . Also, the melting point is /2
If it is above 0°C, it will dissolve in asphalt,
In particular, it is difficult to dissolve in asphalt at low temperatures, resulting in a very slow dissolution of the rubber.
