Abstract

The invention discloses a separating pad, a rubber compound and a preparation method thereof, and belongs to the technical field of metal processing accessories. The preparation method of the rubber compound comprises the following steps: S1, adding raw silicone rubber, white carbon black, hydroxyl silicone oil and vinyl trimethoxy silane into an internal mixer, and mixing to obtain a mixture, wherein the rubber compound comprises the following components in parts by weight: 900-1000 parts of the raw silicone rubber, 400 to 500 parts of the white carbon black, 40-60 parts of the hydroxyl silicone oil, and 1 to 5 parts of the vinyl trimethoxy silane; and s2, heating the mixture to 100-110 DEG C, transferring the mixture into a kneading machine, introducing nitrogen, and mixing at 170-190 DEG C to obtain the rubber compound. The invention also provides the separating pad, which comprises a support frame and a wrapping layer, the wrapping layer is prepared by extrusion molding of the rubber compound, and the wrapping layer wraps the outer surface of the support frame. The separating pad is not easy to deform and damage, and does not wear the surface of a stacked object.

Description

technical field [0001] The invention relates to the technical field of metal processing accessories, in particular to a spacer, a rubber compound and a preparation method thereof. Background technique [0002] Most profiles, building materials, stones, plates, etc. often need to be stacked during the production process or storage process or transportation process, but the stacking of such materials needs to correspond from top to bottom, with appropriate intervals and appropriate quantities. stack more, [0003] To ensure the surface quality of such materials. Spacers are placed between these materials to play the role of spacers. Traditionally used spacers are generally felt spacers, asbestos fiber cloth spacers impregnated with fluorine rubber emulsion, wooden spacers, and high-density foam spacers. However, this type of traditional spacer is easy to wear and has a high frequency of replacement, which increases the production, storage, and transportation costs of profile...
