Abstract

PURPOSE:To provide a rubber compsn. suitable for toothed belts, etc., and excellent in heat resistance and adhesion to rubber-reinforced fiber, by compounding a chloroprene rubber with a vulcanizer, a vulcanizing accelerator, and an org. polysulfide compd. CONSTITUTION:A chloroprene rubber is mixed with ZnO, MgO as a vulcanizer, 2-mercaptoimidazoline, etc. as a vulcanizing accelerator, and, in addn., an org. polysulfide compd. to yield the intended rubber compounding compsn. The best addn. of the org. polysulfide compd. is about 0.5-3pts.wt. based on 100pts.wt. rubber. Org. polysulfide compds. include dipentamethylenethiuram tetrasulfide and 4,4'-dithiobisdimorpholine. Toothed belts using the resulting rubber are provided with improved adhesion of backing rubber 1 and toothed rubber 3 to core 2.

Description

[Detailed Description of the Invention] Uninvented is related to combs and applications τ, corrosion resistance,!
: At the same time, a good rubber compounding with organic and non-marry fiber materials,...Wm is proposed.

Conventionally, many studies have been conducted on the former six-layer rubber compound for applications that require qyiAr technicians.

And, it is effective (I don't know about the rubber vinegar compound on each side.

n + ζ, h Loroglene rubber (CI (,) i juice As its cultivation material, it has 4 properties in heat resistance, onone resistance, weather resistance, oil resistance, chemical resistance, and IL resistance, so it is widely used in the middle of the year) Urorogorencom is a regular R, '1n exile', and in addition to Z n O and A4gO, it is also a power loss!

It is also known that good vulcanization can be obtained by using ZnO and MzO (Akanizaki Saki 4!: Vulcanization accelerator for natural comb, 11/L) in terms of the required properties of the rubber. If this is the case, then thiuram mole sulfide is treated as an equivalent because of its processability.

The first base combination 1'a1, i.e., the vulcanization rate 1 was added to Urolorogoleno, Zr+ 0, MgO was added, and the vulcanization process was made 1 and τ2-mercaptoimitano'% (

However, in this case, the corrosion resistance (FFJf; 9° enclosure, due to the use of sulfur) and the corrosion resistance of rubber (the darkness between raw and adhesive 1) It is a violation of rules.

In order to solve the tax problem, in the 7-compound intoxication, 111 sulfide IFβi busy 11 (112-mercapto imitanoline) and how many units 11 sulfide compound 7. - By using both the fibers and the fibers, we maintained the adhesion resistance at a certain level (without causing deterioration), but improved it only when bonding with the fibers.

This principle is presumed to be 1) Ketsugi no Kaku1). That is, the sulfide compound contains more than 1 sulfur in its molecule due to the 1. 'JF41.' has superior adhesive properties. I think you're a talented kid.

There are vulcanization accelerators such as SBR and N'8R, and f1UI sulfurizing agents, but the purpose of this uninvented product is to cure rubber as mentioned above. The purpose is to make the material more resistant to ridges and to have good adhesion to the curved jaw. Therefore, the number of sulfide compounds in the compound corresponds to chloroprene rubber.

Chloroprene rubber is used as the rubber coating for the rubber-coated silk composition. In addition, vulcanizing agents and filling agents, which are not normally used in this product, are added.11. Softeners, anti-aging agents, processing aids, adhesives, etc. can be added as appropriate.

However, in the uninvented Irogomu Toge Strong Barrel IW, organic fibers such as nylon, polyester, aromatic polyamide, etc., and unsealed fibers such as glass are used one by one.

This is a case of Saikozuke 1, and P-1 and P-2 are polysulfide with polysulfide. It should be noted that the above-mentioned rubber @compound is the steepness of the toothed belt.
