Problems solved by technology

[0002] Gray rubber tubes belong to light-colored rubber products. Due to the lack of reinforcing effect of carbon black, the physical properties of rubber are often low, and the aging resistance effect is not ideal. It is far inferior to black rubber products in terms of ozone resistance and UV resistance.
If the gray rubber tube is used outdoors, especially under sunlight, the outer rubber will crack and become dark in a short time, which will affect the service life and appearance

Abstract

The invention discloses an ozone-resistant ultraviolet-resistant gray rubber tube outer adhesive and a preparation method thereof. The adhesive comprises the following raw materials: rubber-plastic alloy rubber, chlorinated polyethylene rubber, zinc oxide, stearic acid, an anti-aging agent, microcrystalline wax 9332F3, an RD136 resin, carbon black N660 and white carbon black 25-30. The adhesive is prepared by a processing technology and a mixing technology. The gray rubber tube outer adhesive prepared by the invention is obvious in physical properties and aging-resistant and ultraviolet-resistant effects. According to the detection within 72 hours under the conditions of the ultraviolet light intensity of 0.8J / m<2> and the temperature of 70 DEG C, the phenomena of color change and cracks are avoided; and moreover, according to an experiment of exposing the finished tube in the sun for 2-3 months, the tube does not have any abnormal change.
