Embodiment Construction

[0024] The content of the present invention will be described in detail below through specific examples. Following is the consumption of each component in embodiment 1~3

[0025] Unit:kg

[0026]

[0027] According to the raw material in the formula listed in the embodiment, the film is made into a film for testing and detection, and the performance comparison of each embodiment is as follows:

[0028]

[0029] From the data in the above table, it can be concluded that the rubber fixing block composition used for the limit of automobile hoses has better original performance, better resistance to hot air aging, excellent low-temperature brittleness, and excellent cooling resistance, which can meet the requirements of different conditions in winter. It is used in the low temperature environment of the region, and the performance of wear resistance and flex crack resistance is also very good, which improves the service life of the product. The rubber fixing block composit...

Abstract

The invention relates to a rubber fixing block composition used for automobile hose limiting. The rubber fixing block consists of the following components in parts by weight: 60-80 parts of butadiene styrene rubber, 80-100 parts of ethylene propylene diene monomer rubber reclaimed rubber, 2-5 parts of zinc oxide, 1-2.0 parts of stearic acid, 2-3 parts of coumarone, 1-2.0 parts of 2,2,4-trimethyl-1,2-dihydroquinoline, 0.2-1 part of N,N-di(beta-naphthyl)ursol, 50-70 parts of carbon black N550, 50-70 parts of high wear-resistant N330, 30-50 parts of light calcium, 40-60 parts of naphthenic oil, 0.2-0.5 part of 1,3-melaniline, 1-2.0 part of 2,2'-disulfbenzothiazole, 0.5-1.0 part of tetrakis(diethyldithiocarbamato-S,S')tellurium and 0.5-1.0 part of sulphur. The rubber fixing block composition has the characteristics of good heat resistance, low temperature resistance, abrasion resistance, weather resistance, ozone resistance, cracking resistance and the like.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a rubber fixing block composition used for limiting automobile hoses. Background technique [0002] With the rapid development of the automobile industry, the structure of the internal parts of the automobile is becoming more and more complex, and the connection problems between the various parts appear. The connection between the rubber hose and other systems is connected by a clamp. With the continuous upgrading of automobile engine performance and the gradual application of turbocharging technology, the temperature requirements and pressure inside the automobile hose are also increasing. Usually, the connection of the hose clamp is manually selected by manually selecting the end position of the hose. Installation, accompanied by the starting operation of the engine, the reciprocating movement of temperature and pressure, resulting in the displacement of the clamp and th...
