Example Embodiment

[0024] The embodiment of the formula for the inner layer glue of the heat-resistant hose reinforced with plant fibers in the present invention:

[0025] In parts by mass

[0026]

[0027]

[0028] According to the raw materials in the formula listed in the implementation, the film is made into a film for testing. The performance comparison of the heat-resistant rubber tube reinforced with plant fiber and the rubber tube reinforced with single carbon black is as follows:

[0029]

[0030]

[0031] From the data in the above table, it can be concluded that the inner rubber of the heat-resistant hose reinforced with plant fibers has better heat resistance than the inner rubber of a single reinforcing system hose. Resistance, heat resistance, water vapor resistance, coolant resistance, ozone resistance, at the same time compression performance and elasticity are also very good, can also expand the capacity of the compound to reduce costs, and can better meet the conditions of long-term h...

Abstract

The invention relates to heat-resistant hose lining reinforced by plant fiber. The heat-resistant hose lining is prepared from crude ethylene propylene diene rubber, light active zinc oxide, polyethylene glycol, stearic acid, antioxidant MB (2-Mercaptobenzimidazole), antioxidant DD, fast extruding furnace carbon black N550, half reinforcement carbon black N774, soybean protein processed by using a vinylsilane coupling agent, a plasticizer DOTP (Dioctylterephthalate), a coupling agent Si-69, an accelerator M (2- Mercaptobenzimidazole), an accelerator TMTD (Tetramethyl Thiuram Disulfide), an accelerator BZ (Zinc Dibutyl Dithiocaarbamate), an accelerator CZ (N-cyclohex-yl-2-benzothiazole) and insoluble sulfur. Compared with the single reinforcement system hose lining, the formula of the heat-resistant hose reinforced by the plant fiber has the advantages of better heat resistance, hot water vapor resistance, liquid coolant resistance, ozone resistance, compressibility and elasticity; in addition, the cost can be reduced by enlarging the capacity of gross rubber; therefore, the requirements of heating system and cooling circulation system hoses which are utilized under a heat aging condition for a long time can be better met.

Description

technical field [0001] The invention relates to an inner layer glue of a rubber hose, in particular to a heat-resistant rubber hose inner layer glue reinforced with plant fibers. Background technique [0002] Soybean is one of the important crops in the world today. Soybean resources in northern China are very rich. Soybean contains a lot of soybean protein, and soybean protein contains a lot of plant fiber. By using the good water solubility and reactivity of soybean protein, it can be Modify it to improve its practical value. Modified soybean protein is widely used in food industry, wood adhesives, adding modified plastics and rubber, etc. Besides soybeans, rice, wheat and many vegetables contain a lot of plant fiber. Because soybeans have a large yield, relatively low price and relatively simple production process, they are suitable for industrial development. [0003] Soybean protein fiber belongs to the category of regenerated plant protein fiber. It uses oil-pressed ...
