Detailed Description
For the purpose of illustrating the technical content, the constructional features, the achieved objects and the effects of the invention in detail, reference will be made to the following detailed description of the embodiments in conjunction with the accompanying drawings.
The application discloses an acid and alkali resistant super wear resistant wringing roller which is applied to acid washing or alkali washing processes of galvanized steel sheet and other production equipment. In the production process of galvanized steel sheets, research and development personnel find that the service life of the deviation rectifying wringing roller at the No. 5-6 (or No. 6-7) position of the pickling process is short, and the service cycle is usually only 10-15 days. Through analysis, the squeezing roller in the process not only squeezes acid liquor on the surface of the steel plate to be dry, but also does not lead the acid liquor to be brought into the next procedure, so that the conductivity of a cleaning section does not exceed the standard, but also ensures that the surfaces of the steel plate and the rubber roller do not slide relatively in the extrusion process of the steel plate, so that the static friction force is increased, the abrasion is reduced, and simultaneously the correction function of the steel plate is borne, and the primer bonding and breaking force of the common rubber roller is insufficient, so that the primer is easy to separate from the iron core.
Therefore, the application provides an acid and alkali resistant super wear-resistant drying roll, which comprises an iron core 1, an adhesive bonding agent layer 2, a primer 3 and a surface adhesive 4, wherein the adhesive bonding agent layer and the primer are sequentially coated outside the iron core, and the surface adhesive is combined outside the primer layer, and is shown in the figure 1.
Wherein the base rubber 3 is mainly nitrile rubber, and 15-30% of tackifying resin is added. The tackifying resin can be selected from heat-reactive phenolic resin. The base glue has the bonding breaking force of 8-11Mpa, and under the parameter condition, the base glue can provide better anti-fatigue and high-strength bonding force, so that the base glue and the iron core are not easy to separate, and the service life of the drying roller is prolonged. The adhesive breaking force represents the adhesive strength between rubber and metal, unit Mpa, and is calculated by the formula
The surface adhesive material needs to meet the requirements that the acid resistance coefficient is more than or equal to 90 percent, the alkali resistance coefficient is more than or equal to 95 percent, and the Akron abrasion coefficient of the reaction abrasion resistance is less than or equal to 0.05M 3 1.61Km. In order to avoid the slippage when the surface glue is contacted with the steel plate, 15-20% of super wear-resistant material is also added into the surface glue. In one embodiment, the super abrasive material is selected from ceramic powder or tetrafluoroethylene powder. In order to uniformly disperse the super wear-resistant material in the surface glue, the super wear-resistant material in a particle or powder form can be also selected and added in the surface glue, and the particle size of the super wear-resistant material is 10-1000 microns. The super wear-resistant material is added into the surface glue, so that the friction coefficient between the surface glue and the steel plate can be increased, the relative sliding between the steel plate and the surface of the rubber roller in the extrusion process is reduced, the abrasion is reduced, the service life of the squeezing roller is prolonged, and the acid liquor squeezing effect on the surface of the steel plate can be ensured.
The surface rubber comprises an elastomer and an additive, wherein the elastomer is selected from natural rubber latex, synthetic rubber solution or a combination thereof. The additives include fillers, elastomers, curing agents, processing oils, antioxidants, plasticizers, resins, flame retardants, extender oils, lubricants, or any combination thereof.

The primer is 1/4 of the total thickness of the rubber coating, and vulcanization treatment is carried out after the rubber coating is finished, so that the acid-base resistant super-wear-resistant drying roll is obtained.
