Description
Technical field
The utility model belongs to the rubber roll technical field, is specifically related to a kind of paper grade (stock) polyurethane rubber roller.
Background technology
In recent years, along with paper industry develops to high speed, maximization direction, original ordinary rubber rubber roll is subjected to stern challenge, the more and more requirement of the large-scale paper machine of incompatibility in the tolerance of linear pressure.For this reason, polyurethane progressively enters people's the visual field, polyurethane rubber is compared with General Purpose Rubber, has remarkable performance, it has high strength, high-wearing feature, broad hardness range, and it outstanding still has elastomeric characteristics under high rigidity, is exactly to give birth to for papermaking rubber roller seemingly, these characteristics of polyurethane are doomed that it can be used widely in paper industry.But, along with range of application enlarges, the deep of Application Areas also exposed some weakness that are difficult to overcome of polyurethane, and polyurethane is high polar polymer, has the group of these the very easily hydrolysis of ester group, amido, hydroxyl and isocyanate group, alcoholysis, aminolysis in strand.We know polyurethane owing to have excellent rerum natura, the excellent rerum natura of it these is the optimal selection of the large-scale squeezing rubber roll of high line pressure in the papermaking rubber roller, but large-scale pressure roller are all having water, work in the environment of papermaking chemical product liquid, and the weakness of polyurethane is also just in time at this, technical staff author is in order to allow polyurethane keep stable in this environment, do one's utmost to seek the whole bag of tricks and improve its performance to adapt to above-mentioned working environment, such as covering by the end group envelope, the anti-hydrolysis compound of grafting, add hydrolysis-resisting agent, this enough makes polyurethane adapt to the basic demand of squeezing rubber roll in the change of the performance of rubber own, but this but produces little effect to the bonding of polyurethane and roll body.Because the matrix of polyurethane adhesive is steel (comprising carbon steel, cast iron etc.), steel run into water, even few moisture content will oxidation, get rusty, the steel degraded that the metal oxide that produces then can catalyze polyurethane of getting rusty, can separate out more moisture content, so just form a chain reaction, caused destructive consequence at last: come unstuck.
In fact, the hydrolysis of polyurethane is a necessary process, as rubber roll, the life-span of glue-line is 3-5 only also, the hydrolysis of polyurethane glue-line is a progressively process of development in this 3-5, after improved polyurethane generation hydrolysis, its intensity is still greater than General Purpose Rubber, the degree of its degraded is still at tolerance interval, but bonding early damage has shortened the life-span of glue-line greatly, this is only the key and the essence place of problem, is to improve polyurethane rubber roller life-span effective means so improve bonding situation.
Polyurethane and roll body bond failure process are: polyurethane skin layer hydrolysis → hydrolytic process arrives get rusty → the quicken hydrolysis → come unstuck of bonding plane → roll body to the inner developing water process of separating.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to design the technical scheme of the polyurethane rubber roller that a kind of long service life is provided.
Described a kind of paper grade (stock) polyurethane rubber roller, comprise that roll body and coating are arranged on the polyurethane rubber layer on the roll body, it is characterized in that between described roll body and the polyurethane rubber layer adhesive linkage being set, adhesive linkage is bonding to be arranged on the roll body, and the polyurethane rubber layer is bonding to be arranged on the adhesive linkage.
Described a kind of paper grade (stock) polyurethane rubber roller is characterized in that the hardness of the hardness of described adhesive linkage greater than the polyurethane rubber layer.
Described a kind of paper grade (stock) polyurethane rubber roller is characterized in that described thickness of adhibited layer is 3-4mm.
Described a kind of paper grade (stock) polyurethane rubber roller is characterized in that described adhesive linkage is for to be made of polar rubber, epoxy polymer, oligomer and crosslinking agent.
Above-mentioned a kind of paper grade (stock) polyurethane rubber roller, between roll body and polyurethane rubber layer, adhesive linkage is set, this adhesive linkage is made up of the multiple polymers co-crosslinking, this adhesive linkage hardness exceeds 5SHD hardness than layer of polyurethane, approach hard material, the adhesive strength of itself and iron core is high, and this layer compound hydrolysis is ageing-resistant.It is bonding that this composite material and polyurethane can reach sufficient two-phase by means such as coupling, crosslinked, diffusions again mutually.When the polyurethane hydrolysis arrived this interface, hydrolysis can be to in-house development.Clad can has just had assurance to roller core bonding.Thereby avoided because the degumming phenomenon that the polyurethane hydrolysis occurs has good serviceability, and prolonged the service life of polyurethane rubber roller greatly.
