Drum rubber coating manufacturers analyze the adhesive that cannot be overlooked in drum rubber coating

In the process of drum rubberization, the rubber plate is wear-resistant and resistant to aging, with a high friction coefficient, and exhibits good adaptability to harsh working environments. The adhesive firmly bonds the wear-resistant rubber plate to the metal surface of the drum. If the rubber plate becomes delaminated or detaches during use, even the best rubber plate will be scrapped, and may even cause significant damage to the drum. Therefore, focusing solely on the rubber plate in drum rubberization is insufficient; the adhesive should also not be overlooked.
The working environment of drums is generally harsh, where impacts from materials and vibrations from belts, as well as corrosion, oxidation, and aging, all have a significant impact on the quality of the drum's rubber coating. The adhesive used for drum rubber coating must meet these conditions to be truly effective.
Cold vulcanization roller rubber coating boasts simplicity in materials and the convenience of on-site construction. Apart from these features, cold vulcanization roller rubber coating surpasses ordinary cold vulcanization roller rubber coating in terms of bonding strength, bonding efficiency, and application effect, gradually becoming the preferred choice for on-site roller rubber coating among various enterprises. The biggest difference between cold vulcanization roller rubber coating and ordinary cold vulcanization rubber coating lies in the bonding agent.
Adhesive force
The cold vulcanization adhesive CV2000 is suitable for bonding rubber, metal, leather, and fabric, with a bonding strength that exceeds the German DIN industrial standard and is comparable to the strength of hot vulcanization.
Environmental adaptability
Resistant to water, oil, acid, alkali, and aging, it maintains its bonding strength basically unchanged after working in outdoor environments for several years.
Characteristics of adhesive layer
The cured adhesive layer is flexible, moderately hard, resistant to bending, has high tear resistance, and exhibits a certain degree of elongation at break. The flexible adhesive layer can effectively cope with various stresses encountered during the rotation of the roller, reducing damage caused by impact and vibration, and the roller's curved surface has excellent passability.
The applicable operating temperature range is -40 to 120℃. It is safe and flame-retardant, and suitable for both above-ground and underground use.

Bonding characteristics
The cold vulcanized glue CV2000 and the semi-vulcanized layer of the CV wear-resistant rubber plate can undergo a vulcanization reaction, integrating together to form a bonding effect similar to that of hot vulcanization. Through vulcanization crosslinking, the entire bonding surface develops stronger adhesive force and enhanced structural integrity.
The curing speed is fast. In a dry environment at room temperature, the glue dries completely within 5-15 minutes after application, and reaches 70% bonding strength after 8 hours of pasting.
Apply two coats of cold vulcanization glue CV2000 onto the roller surface. Apply the second coat after the first coat is completely dry. When the second coat is semi-dry (test with the back of your finger, slightly sticky but not adhering to the back of your finger), proceed with bonding and fitting. Immediately after fitting, a sufficiently strong adhesive force can be obtained. For the semi-vulcanized layer of the wear-resistant rubber plate, only one coat of cold vulcanization glue CV2000 is required.
