Problems solved by technology

[0005] This invention is an environmentally friendly nitrile rubber molding mortar. Because nitrile rubber is non-crystalline rubber, the tensile strength is only 3-4.5MPa, and it must be reinforced to have dynamic use value under force. Therefore, it is only suitable for Use in environments with low requirements; the glue solvent is a mixture of ethyl acetate 18-22, 120# gasoline 38-42, and acetone 38-42. From the perspective of the mixture content and each solvent, gasoline does not mix with ethyl acetate in the mixed solvent. Ester and acetone react, only soluble in leather, acetone can dissolve nitrile rubber and fiber, so this mixed solvent plays a major role in dissolving acetone and gasoline, and acetone is a toxic substance, it is only low toxicity, not It is non-toxic; the preparation method of the mucilage plays a vital role in the performance and use of the mucilage. If the dissolution is not complete, the mucilage will easily form agglomeration when stirred directly, and its resistance is large, which will damage the stirring rod and the mixer. If the proportion of glue is too large, the stirring friction will be too large, the local temperature will be too high, and glue particles will easily appear. If the proportion of soaking glue is too small, the stirring friction will be too small, and glue particles will easily appear.

Abstract

The invention discloses a rubber paste material of a rubber roller and a preparation method of the rubber paste material and belongs to the field of rubber preparation. The rubber paste material is prepared from the following specific components in percentage by mass: 45 to 58 percent of raw nitrile butadiene rubber, 30 to 35 percent of carbon black, 1.5 to 2.5 percent of a plasticizer, 1 to 2 percent of a bonding agent, 4 to 7.2 percent of liquid nitrile butadiene, 0.2 to 0.4 percent of an accelerator, 3.5 to 4.5 percent of sulfur, 0.2 to 0.4 percent of stearic acid, 1 to 2 percent of zinc oxide and 0.6 to 1.0 percent of an anti-ageing agent. The preparation method comprises the following preparation steps: mixing master batch; carrying out two-section vulcanization on the master batch; preparing rubber paste; immersing the rubber paste; stirring the rubber paste; diluting the rubber paste to obtain a finished product. The rubber paste material of the rubber roller, provided by the invention, has the characteristics of good flowability and great viscosity at room temperature; a sticky roller core, and the nitrile butadiene rubber or a sticky nitrile butadiene rubber layer are densely molded; in a vulcanization process, crosslinking is carried out, so that the bonding strength between the roller core and the nitrile butadiene rubber is improved and the utilization period of therubber roller is prolonged.

Description

technical field [0001] The invention belongs to the field of rubber preparation, and in particular relates to a rubber roller glue material and a preparation method thereof. Background technique [0002] With the increasingly fierce competition in the rubber roller market, the quality of rubber rollers, especially the requirements for the adhesive strength of rubber roller glue, is constantly increasing. In order to meet the requirements of high line speed units for the use of rubber rollers, the service life of rubber rollers should be extended. [0003] The solvent that needs to be added in the preparation process of the existing rubber roller glue material has a relatively strong pungent smell. When wrapping the film directly on the roller core brushed with adhesive, because the self-adhesiveness of nitrile rubber is poor when laminating and molding, the adhesive on the roller core will not be sticky after drying, so that the film cannot be tightly pasted on the roller. ...
