Abstract

The invention discloses a special self-sinking rubber pipe for aerated oxygenation. The self-sinking rubber pipe comprises the following specific components in parts by weight: 88-102 parts of PVC (Polyvinyl Chloride) resin, 45-65 parts of dioctyl phthalate, 38-54 parts of heavy calcium, 1-3 parts of a calcium-zinc composite stabilizer, 8-16 parts of epoxidized soybean oil, 16-25 parts of superfine iron powder, 5-12 parts of nitrile rubber P83, 0.6-1.5 parts of an antioxidant, 3-6 parts of ACR (Acrylic Ester) resin, 0.1-1 part of an ultraviolet light absorber UV-531 and 0.3-0.8 part of PE (Poly Ethylene) wax. The invention also discloses a manufacturing method of the special self-sinking rubber pipe for the aerated oxygenation. The self-sinking rubber pipe is resistant to strong acid and strong base corrosion, unlikely to age and crack, and long in service life; the use of the self-sinking rubber pipe is not affected under high-temperature or low-temperature conditions.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, and relates to an aeration tube, in particular to a special self-sinking rubber tube for aeration and aeration and a manufacturing method thereof. Background technique [0002] In aquaculture, the oxygen content in the water is often increased by means of an aeration tube. The aeration tube is a kind of pipe made by extruding rubber, plastic and various polymer additives. The visible micropores, when the compressed gas is filled into the tube, due to the pressure, the expansion gas of the tube is discharged from the small holes, because the excluded bubbles are very small and have a large contact area with the water body, which can increase the dissolved oxygen in the water body in a short time. The oxygen tubes currently on the market tend to harden, age and crack due to long-term immersion in water and direct sunlight, and the use cost is relatively high. Contents of the invention [000...
