Abstract
The invention discloses a calendar bowl with a rubber coating composite. The calendar bowl comprises a bowl shaft and a bowl sleeve. The bowl sleeve comprises a bowl sleeve lining ring and a rubber coating layer. The two ends of the bowl shaft are provided with bearings. A coupler is arranged on the outer side of the bearing, located on one side, of the bowl shaft. The rubber coating layer comprises the rubber coating composite and an adhesion agent. The rubber coating composite comprises, by weight, PET, EVA, a bulking agent, an anti-oxidant and polysiloxane. The adhesion agent comprises, by weight, a curing agent, an accelerant, a needle-like reinforcing filler and m-benzol unsaturated resin. The bowl shaft and the bowl sleeve can be machined independently. The defect that an existing calendar bowl is prone to looseness is overcome. The surface of the bowl sleeve is coated with the rubber coating composite and the adhesion agent, so that the bowl sleeve has the advantages of being resistant to press, abrasion, aging caused by high temperature, aging caused by dampness and acid-base corrosion and is long in service life. A waste calendar can be reused. The degree of finish, the degree of flatness, the density and the like of paper can be improved, and the calendar bowl is suitable for producing high-grade paper.
