Embodiment Construction

[0034] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention.

[0035] The invention discloses a preparation formula of a synthetic rubber hose for the inlet and outlet of an intercooler that satisfies the National VI emission standard. Calcium oxide 6-11 parts, tackifier 2-5 parts, odorless DCP 1-2 parts, high wear-resistant carbon black 38-60 parts, plasticizer 3-5 parts, barium sulfate 8-12 parts. The working principle and advantages of the present invention are: according to this formula, the fluororubber (FKM) with high adhesive properties) and silicone rubber (VMQ) have a good adhesive effect, and under the hot air aging state of 220°C*168H , the bonding strength of fluororubber (FKM)) and silicone rubber (VMQ) is still > 0.5KN / m, which meets...

Abstract

The invention discloses a preparation formula of a synthetic rubber tube for gas inlet and outlet of an intercooler meeting the national sixth emission standard. The formula comprises the following components in parts by weight: 100-120 parts of fluororubber, 6-8 parts of active magnesium oxide, 6-11 parts of calcium hydroxide, 2-5 parts of a tackifier, 1-2 parts of odorless DCP, 38-60 parts of high-wear-resistance carbon black, 3-5 parts of a plasticizer and 8-12 parts of barium sulfate. Meanwhile, the invention discloses a preparation method and preparation equipment of the formula; and the obtained fluororubber (FKM) with the high bonding characteristic has a good bonding effect with the silicone rubber (VMQ), and the bonding strength of the fluororubber (FKM) and the silicone rubber (VMQ) is still more than 0.5 KN / m in a 220 DEG C * 168H hot air aging state, so that the technical standard of T7 high-end commercial vehicles is met. According to the invention, the bonding capacity of the fluororubber (FKM) and the silicone rubber (VMQ) is improved, and thus the purpose of reducing the risk of failure in the use process of the product is achieved. The method is suitable for the technical field of rubber production processes.

Description

technical field [0001] The invention belongs to the technical field of rubber production technology, and specifically relates to a preparation formula, a preparation method and special preparation equipment for a synthetic rubber hose for intercooler air inlet and outlet meeting the National VI emission standard. Background technique [0002] At present, ordinary silica gel or fluorosilicone can meet the requirements of long-term temperature resistance of 200 ° C, but cannot meet the requirements of oil and gas resistance. Under long-term working conditions, the structure made of pure silicone or fluorosilicone will leak oil, resulting in product failure. In order to meet the problems of long-term high temperature resistance and oil gas penetration resistance, the industry generally adopts a process structure in which the inner layer is made of fluorine rubber (FKM) and the middle layer is made of silica gel (VMQ). However, due to the properties of fluorine rubber (FKM) and...
