Embodiment 1

[0018] Composition formula: 70g of natural rubber, 30g of styrene-butadiene rubber, 20g of rosin resin, 3g of stearic acid, 3g of zinc oxide, 4g of accelerator TMTD, and 80ml of xylene.

[0019] The natural rubber and styrene-butadiene rubber were masticated in three stages with an open mill, and the next stage of mastication was carried out after each stage of mastication was stopped for more than 8 hours. The rubber components after mastication are kneaded together, and the rest of the components are added after kneading, and kneaded for 5-10 minutes. The rubber material after banburying is taken out, and the film is parked for 2-4 hours; then it is heated on a heat mixer and cut into pieces. Beat the film and ethyl acetate on a beater for 8-12 hours, and finally filter with a 200-mesh filter. Sealed in a plastic bucket for 30 months and opened after 30 months, the self-adhesive has no solidification and has fluidity.

Embodiment 2

[0021] Get a piece of automobile tire material, wipe off the surface dirt with a damp cloth, and smear the self-adhesive made in embodiment 1 after air-drying. Apply stickers to a clean bicycle inner tube, and leave one corner free of stickers. Then paste the bicycle inner tube material on the car tire material, and press it from the center to the surroundings several times with your hands to discharge the air. After standing for 72 hours, clamp the above-mentioned unbonded corner with a vise and pull it apart forcefully. As a result, the original adhesion face is destroyed.

Abstract

The invention relates to an adhesive sticker for bonding rubber products. The adhesive sticker mainly comprises 100 parts of rubber, 5-20 parts of tackfying resin, 2-5 parts of accelerating agent, 5-10 parts of activating agent and a right amount of solvent. The adhesive sticker does not contain a vulcanized agent, can be stored for long term and can be used for conveniently and firmly bonding the rubber products. The invention also relates to a rubber type non-drying tape containing the adhesive sticker.

Description

technical field [0001] The invention relates to a polymer composition, in particular to a self-adhesive. Background technique [0002] Rubber products often need to be attached with some text or graphic identification, such as manufacturer, product model, registered trademark and so on. And in many cases, it is desirable for these signs to have a striking color. CN1067205 discloses a method for producing patterned molded products, and CN1060430 discloses a method for producing embossed molded products. The logo is attached to the tire by die-casting, and the operation is relatively complicated. Another method is to use decals, where the logo to be transferred is made into a decal and then attached to the rubber product with an adhesive. The adhesive has low initial tack, so a sintering or heat curing step is usually required. In addition, since the adhesive contains a cross-linking agent (curing agent), the adhesive has a limited storage period and becomes invalid after b...
