Problems solved by technology

[0003] At present, it is difficult for many domestic rubber product manufacturers to quickly spray out the paraffin from the inside of the rubber, forming a thick layer of paraffin on the surface of the rubber, and some even increase the amount of paraffin greatly. purpose, some even have difficulty spraying out paraffin for a long time
[0004] Nowadays, there are many kinds of paraffin wax in our country, which may also lead to rubber technicians not choosing the type of paraffin wax or its combination well, resulting in the paraffin wax not being able to flow freely and quickly from the inside of the rubber.

Abstract

The invention provides a quick wax spray rubber composition. The composition is characterized by comprising the following components in parts by weight: 100 parts of rubber, 4-6 parts of organic active agent, 0.5-1.5 parts of inorganic active agent, 2-4 parts of anti-aging agent, 5-8 parts of paraffin, 2-3 parts of processing aid, 20-80 parts of reinforcing agent, 5-15 parts of plasticizer, 1.8-2.5 parts of accelerator and 1.5-2 parts of vulcanizing agent. The invention also provides a preparation method of the quick wax spray rubber composition. The method is characterized by comprising the following steps of: making rubber and parking; sulphurating; and finally, parking. In the invention, a paraffin layer can be quickly adhered on the surface of the rubber within a short time, and the paraffin can even be quickly sprayed out of the interior of a rubber product in a slightly dynamic state so as to better prevent aging by ozone, clear up friction abnormal sound on the surface of the rubber, keep a self-lubricating function and reduce the friction coefficient, and moreover, the anti-aging agent cannot be taken out of the surface so as to avoid blushing and over quick aging.

Description

technical field [0001] The invention relates to a formula of rapid wax spraying of a rubber composition and a processing technology thereof. Background technique [0002] Many foreign rubber products, such as shock absorbing products, stabilizer bar bushings, rubber pads and other products, have a thick protective paraffin layer on the surface. Lubricating function, reducing the coefficient of friction, and does not take the anti-aging agent out of the surface to cause blooming and premature aging. [0003] At present, it is difficult for many domestic rubber product manufacturers to quickly spray out the paraffin from the inside of the rubber, forming a thick layer of paraffin on the surface of the rubber, and some even increase the amount of paraffin greatly. For some purposes, it is even difficult to spray out paraffin for a long time. [0004] Nowadays, there are many kinds of paraffin wax in our country, which may also cause rubber technicians to choose the type of pa...
