Problems solved by technology

The problem with ultrasonic welding of rubber V-belts is that they cannot be welded in groups, but can only be welded individually, resulting in low production efficiency.
And because it is a welded connection, the joint strength has different degrees of loss

Abstract

The invention relates to polyester film base rubber matrix used in belt drive unit that is made up from natural rubber 60-80 portions, tetraphene rubber 1500 20-40 portions, carbon white 10-20 portions, half active black 15-30 portions, high abrasion resistant carbon black 30-50 portions, zinc oxide 2-8 portions, stearic acid 1-3 portions, anti-aging agent A 0.5-2 portins, anti-aging D 0.5-2 portions, adhesive RS 2-5 portions, adhesive A 1-3 portions, sulfur 1-4 portions, accelerant TT 0.01-0.05 portion, accelerant M 0.2-0.6 portion, accelerant DM 1-3 portions, and 203 tie resin 2-5 portions. The advantage of the invention is that it could adhere strongly because of the stickiness of the rubber on the surface of the film base. The improvement would sharply increase the working efficiency.

Description

technical field [0001] The invention relates to a rubber adhesive for bonding polyester (PET) sheet bases used in belt transmission devices. Background technique [0002] Polyester (PET) film base is a film base made of high-viscosity polyethylene terephthalate stretched multiple times in one direction. After dipping treatment, it is used in rubber V-belt products instead of rubber V-belts. Line layer skeleton. However, since the chemical properties of the polyester (PET) film base itself are not very active and its rigidity is too strong, it is very difficult to connect the film base. The currently commonly used process is to first cut the film base according to the size of the V-belt, and then weld it into a ring with an ultrasonic welding machine one by one, and then make a raw rubber strip made of mixed rubber on the molding machine. Combined into a V-belt core and then wrapped with cloth by a cloth wrapping machine, it is assembled on a vulcanizing machine for vulcani...
