[0025] In parts by mass

[0026]

[0027]

[0028] According to the raw materials in the formula listed in the examples, the film was made into a film for testing and testing. The performance comparison between the heat-resistant rubber hose inner layer rubber reinforced with plant fiber and the rubber hose formula 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 layer glue of the heat-resistant rubber hose reinforced with plant fiber has better heat resistance than the inner layer glue of the single-reinforced hose. Resistance, hot water vapor resistance, cooling liquid resistance, ozone resistance, good compression performance and elasticity at the same time, can also expand the capacity of the compound to reduce costs, and can better meet the long-term heat aging conditions Requirements for hoses used in heating systems and cooling circulation systems.

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 ...
