Problems solved by technology

[0002] Existing construction machinery vibrator rubber hoses are prone to cracks after being exposed to the sun and under harsh environmental conditions. The original rubber hoses were made of natural rubber, styrene-butadiene rubber and regenerated rubber, but they used clay as a filler. The surface of the hose is rough, hard at room temperature, and has a large specific gravity, so it is easy to break

Abstract

The invention discloses a rubber hose. The hose comprises raw materials and additives. Raw materials comprise chlorinated polyethylene, natural rubber and regenerated rubber. Additives comprise a filling agent, a reinforcing agent, a sun-screening agent, a plasticizing agent and an accessory agent, wherein the filling agent is calcium carbonate, the reinforcing agent is carbon black, the sun-screening agent is paraffin, and the plasticizing agent is phosphoric acid fat alcohol ester, adipate or epoxidized soybean oil. The hose has the advantages that the chlorinated polyethylene, the natural rubber and the regenerated rubber are used, the hose is cold resistant and age resistant, the cold resistance of the hose is increased if the natural rubber amount is increased, and the hose is high in tension intensity and free from cracks.

Description

technical field [0001] The invention relates to a rubber hose. Background technique [0002] Existing construction machinery vibrator rubber hoses are prone to cracks after being exposed to the sun and under harsh environmental conditions. The original rubber hoses were made of natural rubber, styrene-butadiene rubber and regenerated rubber, but they used clay as a filler. The surface of the hose is rough, hard at room temperature, and has a large specific gravity, so it is easy to break. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a rubber hose. [0004] The technical scheme adopted in the present invention: [0005] A rubber hose, including raw materials and additives, the raw materials include chlorinated polyethylene, natural rubber and recycled rubber; the additives include fillers, reinforcing agents, sunscreen agents, plasticizers a...
