Abstract
The invention relates to a method for realizing the conglutination of rubber material and metal in the vulcanization process, which is characterized in that in the compounding of the rubber material, organic cobalt salt is used as a adhesion promoter and N, N'-metaphenylene maleimide as a bonding addition agent. The bonding strength of the rubber and the metal of the method is comparable to the 'resorcinol-formaldehyde-silica' system and the compression set of the rubber material is improved.
Description
Technical field
The present invention relates to the Rubber processing industry in the chemical industry field, promptly the cooperation of rubber and complete processing specifically, relate to elastomeric material and metal species skeleton and realize adherent rubber compounding technique in vulcanization of rubber processes.
Background technology
Rubber item particularly is the rubber item of representative with the vibration damping purposes, need mainly be steel plate, spring and so on metal mostly, is strengthened.This based article in use to stand mostly different frequency and amplitude back and forth, torsional deformation, therefore as the rubber of resilient material and the junction between the inflexible metalwork, also be the very easy generation fatigue in bonding place and cause coming unstuck or broken glue.One of them exemplary is exactly the damping products that uses on the rolling stock a--elastic side bearing, along with comprehensively speed-raising and the increase of weight-carrying capacity and the further raising of durable life requirements of locomotive, continued to use originally for many years in order to realize that elastomeric material and metallic framework directly bonding in sulfidation "-first-Bai " coupled system can not satisfy science and technology and industrial growing needs.
So-called "-first-Bai " binding system is by formaldehyde donor (vulkacit H, be called for short HMT) or the bonding enhancement system of ternary formed of methylene radical donor (hexa methoxy methyl melamine is called for short HMMM), monomer Resorcinol or resin type Resorcinol and three components of white carbon black.Its principle mainly is to utilize formaldehyde or methylene radical donor and Resorcinol (monomer or resin) reaction to generate to have high bonding active resorcinol-formaldehyde resin, and white carbon black can produce synergy to this adhesion process, further improves bonding effect.This bonding enhancement system, from the exploitation so far, industrial used 40 surplus year, effect is remarkable.But, its main drawback also clearly, at first, it produce and use in have that generally acknowledged toxicant--formaldehyde discharges, both endangered production environment, be applied in and more endanger passenger masses on the locomotive.Secondly, because "-first-Bai " system utilizes the bonding activity of resorcinol-formaldehyde resin, its rigidity is bigger, is unfavorable for improving the adherent fatigue resistance, the compression set of the elastomeric material that obtains is also bigger than normal, is dissatisfactory as damping products.
Summary of the invention
The shortcoming of bonding enhancement system that the present invention is intended to overcome is traditional "-first-Bai ", provide a kind of and do not utilize "-first-Bai " system, thereby the drawback of formaldehydeless release, can also reduce elastomeric material compression set in sulfidation, realize rubber and metallic substance adherent method.
The present invention is achieved in that and it is characterized in that adopting organic cobalt salt in the cooperation of elastomeric material is adhesionpromoter, adopts N, and N '-metaphenylene maleimide is a bonding agent.
Organic cobalt salt is applied to rail tyre, adhesionpromoter as rubber and brass-plated steel wire cord has also had the history in year surplus in the of 30, it is said and use cobalt salt can improve bond properties between rubber and the Coppered Steel Wire cord, performances such as particularly anti-aging, moisture-proof heat.But be used for the directly bonding of rubber and steel plate for cobalt salt, do not appear in the newspapers.The present inventor is through discovering in a large number, the sulfide modifier auxiliary agent N that organic cobalt salt and rubber are commonly used, N '-metaphenylene maleimide (HVA-2) is also with producing synergistic effect, bond strength height not only, can and "-first-Bai " bonding enhancement system than beautiful, and the compression set of sizing material obviously reduces than using "-first-Bai " bonding enhancement system, and fatigue performance improves, so it is particularly suitable to be used for the vibration isolation rubber goods.
Described organic cobalt salt adhesion promotion agent can be selected from one or more in cobalt naphthenate, cobalt stearate or the new cobalt decanoate; Consumption is 100 weight parts in rubber raw materials, is 1～3 weight part.The very few tackify DeGrain of consumption, consumption is too much, and is unfavorable to cost.From bonding effect, particularly suitable to select new cobalt decanoate for use.
The present invention is mainly used in the locomotive damping products, it is elastic side bearing, pretend to elastomeric material and selected the natural rubber that is used for vibration damping aspect over-all properties the best for use, also use a certain proportion of cis-1,4-polybutadiene rubber again, to improve the low-temperature performance of gained rubber damping spare, enable to adapt to the requirement of locomotive when the northern area of China is travelled.These two kinds of dience rubbers and use than, by weight, be preferably 80: 20.
Described bonding agent N, the N '-consumption of metaphenylene maleimide in rubber size is 100 weight parts in rubber raw materials, is preferably 1～3.5 weight part.
Adopt the locomotive of the inventive method trial-production on probation through relevant department with elastic side bearing, satisfied locomotive driving speed and reached 120km/h, load-carrying is brought up to 80 tons from 60 tons, reaches the composite request of 1,600,000 km actual service lifes work-ing life.The more important thing is that this product does not discharge deleterious formaldehyde composition.
Embodiment
With embodiment the present invention is further described in detail below, but the present invention is in no way limited to these embodiment.In the example below, sizing compound formula is all in weight part.The performance of sizing material all records by corresponding national standards.
Embodiment 1～4 and comparative example 1～3
Press the prescription shown in the table 1 and prepare embodiment 1～4 and comparative example 1～3 seven kind of rubber unvulcanizate with opening rubber mixing machine, natural rubber is sneaked into cis-1,4-polybutadiene rubber more in proportion behind over-mastication, it is mixing then to press blended rubber → promotor → strengthening agent, promoting agent, anti-aging agent → adhesionpromoter, all the other auxiliary agents → sulfury order of addition(of ingredients), then, rubber unvulcanizate is turned refining evenly, compacting is sulfided into test piece, carries out the respective item test, and the result is as shown in table 1.
Wherein comparative example 1 is the blank example that does not add any adhesionpromoter, and comparative example 2 is the examples that adopt the bonding enhancement of tradition "-first-Bai " system, and comparative example 3 is single examples with organic cobalt salt.Cobalt salt in the prescription is that content is 20.5% new cobalt decanoate (U.S. RedAvenueChemical Corp. product), sticking RS series resorcinol and stearic 2: 1 eutectics; Sticking A is a kind of formaldehyde donor, chemical name N, N, N ', N "-five methoxyl methyls-N "-melamine methylol.
By table 1 as seen, embodiment 1～4 according to the invention, its bond strength can and traditional "-first-Bai " bonding enhancement system than beautiful, but be much better than traditional "-first-Bai " bonding enhancement system at the compression set aspect of performance.As for the comparative example 1 that does not adopt any bonding enhancement system or the comparative example 3 that only adopts organic cobalt salt relatively, the advantage of the present invention on bond strength is fairly obvious.
