English name :piperidinium piperidine-1-carbodithioate
English alias: piperidinium pentamethylenedithiocarbamate;
Piperidine -1-carbodithioic acid - piperidine (1:1)
CAS no. : 98-77-1
Molecular formula: C11H22N2S2
Molecular weight: 246.4358
Physical and chemical properties: yellow white crystalline powder.
Relative density 1.15-1.20, melting point 160 ℃.
Soluble in water, benzene and tetrahedral carbon, slightly soluble in ethanol and acetone.
Manufacturing method: the product can be prepared by reaction of hexahydropyridine with carbon disulfide at low temperature.
Purpose: use as a super accelerator for natural rubber, synthetic rubber and latex, especially suitable for latex.
Due to its fast curing and vulcanizates flatness is poor, appropriate is used at low temperature (115 ℃), sulfide.
Rubber Accelerator PPD is mainly used for self - sulfur glue, self - sulfur glue, quick - curing glue, leaching products and latex products.
It can also be used as plasticizer and anti - coke agent of G type aerobutyl rubber.
Rubber Accelerator PPD needs to be mixed with catalpa, why not use fatty acid, also can use a small amount of injectant M or light magnesium oxide activation.
It can be used with accelerant M when speed is required.
If Rubber Accelerator PPD is necessary to slow down the thinning speed, it can be added to the thinning delay agent, anti-aging agent MB or lead oxide to inhibit.
The general dosage is 0.25~2.0 and 3.0~1.0 respectively.
(1) Rubber Accelerator PPD is easy to decompose when it is stored or exposed to sunlight and water vapor for a long time, and iron can also accelerate its decomposition. Therefore, it should be stored in a dry and light-free environment and cannot be stored in an iron container.
(2) when it is used in sulfur flavine, it is easy to be burnt in the parking process. Usually, two kinds of mother smelting glue are prepared in advance, which contain sulfur yellow and aini, respectively. Before use, they are mixed and used up within 8h.
