Embodiment Construction

[0013] Below, describe figure 1 The materials and production process of the pressure-resistant rubber tube shown:

[0014] a. The rubber material used in the pressure-resistant rubber hose: the components are proportioned by mass percentage as follows: 45.52% of natural rubber, 19.53% of carbon black, 3.51% of engine oil, 23.44% of filler, 0.39% of paraffin, zinc oxide 1.56%, stearic acid 0.34%, 4010 0.13%, rubber antioxidant RD 0.39%, vulcanization accelerator M 0.16%, rubber accelerator DM 0.16%, rubber accelerator CZ 0.31%, S 0.47%, fiber is 3.91%; wherein the length of the fiber is 1-3mm, and the diameter is 0.015-0.1mm.

[0015] Specifically, the selected fiber has a length of 2 mm and a diameter of 0.04 mm.

[0016] b. After the components of the rubber material are prepared, the rubber is mixed, and then extruded into a pressure-resistant rubber tube at one time. like figure 1 As shown, fibers 2 are distributed in the braid-free rubber hose 1 of the pressure-resista...

Abstract

The invention provides a rubber material and a pressure-resistance rubber hose made of the same. The rubber material comprises the following components by mass percent: 45.52 percent of natural rubber, 19.53 percent of carbon black, 3.51 percent of machine oil, 23.44 percent of filler, 0.39 percent of paraffin, 1.56 percent of zinc oxide, 0.34 percent of stearic acid, 0.13 percent of 4010 (antioxidant), 0.39 percent of rubber antioxidant RD, 0.16 percent of vulcanization accelerator M, 0.16 percent of rubber accelerator DM, 0.31 percent of rubber accelerator CZ, 0.47 percent of S and 3.91 percent of fiber, wherein the length of the fiber is 1-3mm, and the diameter is 0.015-0.1mm. The pressure-resistance rubber hose made of the material is prepared by the following steps of: carrying out rubber mixing by adopting the rubber material and then carrying out one-step extrusion moulding. The fiber is added to the rubber material, and the rubber hose made of the rubber material has good pressure resistance and can replace the traditional braided construction hose. The rubber hose adopts one-step extrusion moulding and has simple production process and few procedures. The fiber is evenly distributed in rubber so that the rubber hose has a compact structure, and the pressure-resistance effect of the rubber hose is better than that of the braided construction hose.

Description

technical field [0001] The invention relates to a rubber material and a pressure-resistant rubber tube using the material. Background technique [0002] Rubber hose and its rubber products are indispensable and important parts of the machinery industry. It is widely used in various sectors of the national economy to transport gaseous, liquid, solid and other substances or various seals, pads (sheets), etc. Rubber hoses are divided into pressure-resistant hoses, low-pressure hoses (working pressure below 0.5mpa) and negative pressure hoses (internal pressure lower than atmospheric pressure) according to their working pressure; according to their cross-sectional structures, they are divided into non-reinforced skeletons. Layered pure rubber hose and reinforced rubber hose with various reinforced skeletons such as (cloth, braided, knitted, circular knitted), etc. Generally, the pressure-resistant hose adopts a structure with a reinforced skeleton, which enhances the compressi...
