Abstract

The invention discloses a tyre rubber vulcanizing technology. An un-vulcanized rubber profile is heated and vulcanized for two times in a vulcanizing machine, and the two-time heating and vulcanizing technology comprises the following steps of: first heating and vulcanizing: introducing high-pressure steam of 1.50 to 1.60MPa, introducing high-pressure medium nitrogen of 2.50 to 3.00MPa after 4 to 5 minutes, and vulcanizing for 8 to 12 minutes by using a charged nitrogen vulcanizing 'pressure maintaining and temperature changing' process; and second heating: introducing the high-pressure steam of 1.50 to 1.60MPa after first heating, introducing the high-pressure medium nitrogen of 2.50 to 3.00MPa after 2 to 4 minutes, vulcanizing for 20 to 30 minutes, exhausting, and finishing vulcanizing. The technology has the advantages of reducing the cost and improving the production efficiency.

Description

A kind of rubber for tire sulfuration process

Technical field

The present invention relates to a kind of rubber vulcanization process, specifically is a kind of rubber for tire sulfuration process that adopts nitrogen as curing medium.

Background technology

One of basic working procedure of producing rubber is the vulcanization of rubber, and traditional vulcanization of rubber technology is in rubber size, to add a certain proportion of sulphur and promoter, and heating is vulcanized then; With linearity, the interchain of original rubber can move freely, when receiving external force; Meeting displacement of strand center and the rubber with solubility characteristic through sulfuration, obtain interchain generation chemical crosslinking and reticulate structure; Make relative motion receive restriction, careless displacement of chain center of gravity and rubber that can only swelling.There is certain defective in this traditional sulfur cross-linking method, like the neat baking process of tire, needs higher energy; Be difficult to control well the precrosslink degree of rubber again, elastomeric material is thinning because of intensification, takes place easily to flow; Cause the inhomogeneities of goods, the waste rubber raw materials.In addition, also there is the long shortcoming of cure time in traditional vulcanization, influences the quantification of its production.

Summary of the invention

Main task of the present invention is to provide a kind of novel rubber for tire sulfuration process, particularly the temperature and the number of times of heating is controlled, and reaches the rubber vulcanization process that improves the production capacity purpose.

In order to solve above technical problem; A kind of rubber for tire sulfuration process of the present invention; Earlier green glue stock, compounding ingredient, filler, vulcanizer are mixed the back and in two rod mills or banbury, begin to take shape the half finished rubber section bar after mixing; It is characterized in that: above-mentioned unvulcanized rubber profile is carried out the sulfuration of heating for twice in vulcanizer; Said twice sulfuration process of heating is: baking for the first time: feed high pressure 1.50-1.60Mpa steam, switch after 4-5 minute and feed high-pressure medium nitrogen 2.50-3.00Mpa, utilize " pressurize alternating temperature " technology sulfuration 8-12 minute of filling the nitrogen sulfuration; After heating for the first time, feed high pressure 1.50-1.60Mpa steam once more, after 2-4 minute, switch feeding high-pressure medium nitrogen 2.50-3.00Mpa once more, to vulcanize 20-30 minute, sulfuration is accomplished in last exhaust.

Advantage of the present invention:

In sulfuration process, general sulfuration divides three phases: induction period, cross-linking reaction stage, network form the stage.

Induction period is sulphur, activator, promoter interaction, and activator solubility in sizing material is increased, and activation promoter makes the bigger intermediate product of reaction a kind of activity of generation between promoter and the sulphur; Further cause rubber molecular chain then and produce crosslinkable rubber macromolecule free radical.

The cross-linking reaction stage: crosslinkable free radical or ion and rubber molecular chain produce reaction, generate cross-bond.

Network forms the stage: the cross-linking reaction in early stage in this stage becomes to accomplishing, and short China, rearrangement and cracking reaction take place the initial cross-bond that forms, and last network tends towards stability the vulcanizate that obtained performance is stable.

In above-mentioned 3 stages of reaction, best in theory sulfuration process is: want induction period to grow big, fast, smooth time of curingprocess rate.Wherein curingprocess rate is fast, assurance be to enhance productivity and reduce cost.

Advantage of the present invention: what the present invention mainly captured is this link of enhancing productivity that reduces cost; Therefore; In the present invention; Adopted twice sulfuration and its cure time and temperature and pressure have been controlled, reached sulfuration process of the present invention and shortened at least 3 minutes than traditional sulfuration process time.

The specific embodiment

Rubber for tire sulfuration process of the present invention is specific as follows:

Earlier green glue stock, compounding ingredient, filler, the vulcanizer of routine mixed the back and in two rod mills or banbury, begin to take shape the half finished rubber section bar after mixing.

Above-mentioned unvulcanized rubber profile is inserted in the vulcanizer model, and unvulcanized rubber profile is made medium at nitrogen, in the steam of HTHP, carries out twice baking.Concrete steps are following: baking for the first time: in capsule, feed high pressure 1.50-1.60Mpa steam; Form the 1.50-1.60MpaMpa high pressure; Switch feeding high-pressure medium nitrogen 2.50-3.00Mpa after 4-5 minute, utilize " pressurize alternating temperature " technology of filling the nitrogen sulfuration to vulcanize 8-12 minute.After heating for the first time, feed high pressure 1.50-1.60Mpa steam once more, after 2-4 minute, switch feeding high-pressure medium nitrogen 2.50-3.00Mpa once more, vulcanize emptying capsule after 20-30 minute, remove tire, accomplish sulfuration.

Adopt this technology to make all-steel radial tyre and can shorten curing cycle, enhance productivity, the sulfuration process of twice heating can reduce cure time 3min than common nitrogen sulfuration process, and every board can be produced more than 1000 tire more in 1 year.
