Embodiment Construction

[0030] Raw materials: according to the proportioning of the following embodiments, the prescription is carried out: (unit: kilogram)

[0031]

[0032] Preparation:

[0033] 1. Material shape

[0034] 1. The EPDM rubber should be selected from products with high Mooney, medium-high ethylene content, medium-low ethylene and norbornene content. This specific implementation mode uses MG47085 produced by DuPont Copper in the United States;

[0035] 2, paraffin oil should select the product of high flash point, high viscosity, low volatility for use, and this embodiment selects domestic 500# paraffin oil for use;

[0036] 3, anti-aging agent selects quinoline anti-aging agent, what this specific implementation mode selects is anti-aging agent RD, in order to enhance the protective effect, the protective system of RD+MB can be used in combination;

[0037] 4. Other materials can be shaped as usual.

[0038] 2. Preparation

[0039] 1. Rubber mixing

[0040] The rubber material...

Abstract

The invention provides a formula of sizing material of a high temperature-resistant hose of an automotive radiator. The sizing material is prepared by the mixture of ethylene propylene diene rubber, sulfur, dicumyl peroxide, antioxidant, a reinforcing agent and a plasticizer. The invention improves the heat resistance of the hose of the radiator by changing the formula of the sizing material of the hose of the automotive radiator and after being vulcanized and cross-linked, the sizing material can form a carbon-carbon cross link which has higher bond energy than a cross link formed after the sizing material taking sulfur as a vulcanization system is vulcanized, and can also meet the requirement of the working temperature of 150 DEG C (the instant highest temperature can reach 175 DEG C). Simutaneously, the properties of the hose such as tension strength at break, elongation at break, ozone ageing resistance, low-temperature resistance, vibration fatigue resistance, cooling fluid resistance, compression set, etc. can all meet the international requirements of the 150 DEG C level.

Description

technical field [0001] The invention relates to the technical field of automobile radiator hoses, in particular to a high-temperature resistant automobile radiator hose compound formula. Background technique [0002] The car radiator hose is a flexible connection between the car engine and the radiator. Its main function is to transport coolant to ensure the normal and safe operation of the engine. With the development of the automobile industry and the gradual improvement of people's requirements for energy saving and environmental protection of automobiles, automobile engines continue to develop in the direction of light weight and energy saving, which makes the structure of automobile engines more compact, and the space around the engine is narrower, resulting in higher temperatures. As a result, the operating temperature of the radiator hose is getting higher and higher. In the early days, the working temperature of the radiator hose was 100°C, and the formula designed ...
