Abstract
The invention relates to fluidal media conveying pipelines, in particular to a high temperature-resistive pipeline for conveying an antifreezing fluid by using an automobile. The high temperature-resistive pipeline for conveying the antifreezing fluid comprises a one-layer structure, i.e. an SEP rubber material layer (1); or a three-layer structure, i.e. the SEP rubber material layer (1), a reinforcing layer (2) and an external rubber layer, wherein the external rubber layer is compounded on the reinforcing layer (2) and the external rubber layer is made from ethylene acrylate rubber (AEM) (3), an ethylene-vinyl acetate copolymer (EVM) (4), acrylate rubber (HT-ACM) (5) or silicon rubber (VQM) (6); or a four-layer structure, i.e. the SEP rubber material layer (1), the reinforcing layer (2), the external rubber layer and an aluminum-coated glassfiber corrugated pipe sheath (7), wherein the reinforcing layer (2) is made from AR (aramid) fiber, composite glass fiber or metal wires and the external rubber layer is made from the VQM silicon rubber (6). The high temperature-resistive pipeline for conveying the antifreezing fluid can be used for automobiles and motorcycles and can also be used in fields, such as ships, high-speed railways, general machinery and the like.
Description
Technical field
The present invention relates to a kind of flowing medium delivery line, particularly a kind of high temperature resistant pipeline that is used for automobile conveying antifreeze liquid.
Background technique
The design of automobile at present develops to high performance, and topology layout is compacter, and engine compartment temperature significantly improves, and surrounding enviroment are comparatively abominable, and the continuous serviceability temperature that is higher than 170 ℃ is comparatively usual.
The automobile that current use peroxide cure ethylene propylene diene rubber EPDM makes carries the pipeline of antifreeze liquid only can satisfy 150 ℃ of temperature, can not satisfy the needs of higher temperature, though the automobile that adopts silicone rubber VQM to make carries the pipeline of antifreeze liquid can satisfy the needs of high temperature, anti-steam, boiling water and acid resistant alkali aspect are relatively poor.The pipeline of therefore existing cooling system can not adapt to the demand of engine compartment long term high temperature state working environment, carries the antifreeze liquid pipeline thereby demand designing a kind of resistant to elevated temperatures automobile urgently.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of adaptation engine compartment long term high temperature state working environment in order to overcome above technical deficiency, and weatherability is stronger, elasticity and ductility are better, is used for the high temperature resistant pipeline that automobile is carried antifreeze liquid.
The object of the present invention is achieved like this:
The present invention carries the high temperature resistant pipeline of antifreeze liquid, comprises one deck SEP rubber material layer.
Purpose of the present invention can be achieved like this equally:
Carry the high temperature resistant pipeline of antifreeze liquid, be characterized in that design has enhancement layer on SEP rubber material layer, glue-line is AEM ethylene acrylic fat rubber, EVM vinyl-vinyl acetate copolymer or HT-ACM acrylate rubber outside being compounded with on enhancement layer.
Purpose of the present invention equally also can be achieved like this:
Carry the high temperature resistant pipeline of antifreeze liquid, glue-line is a VQM silicone rubber outside being characterized in being compounded with on enhancement layer.
Purpose of the present invention also can be achieved like this:
Carry the high temperature resistant pipeline of antifreeze liquid, be characterized in that outside covering one deck on glue-line AEM ethylene acrylic fat rubber, EVM vinyl-vinyl acetate copolymer, HT-ACM acrylate rubber, the VQM silicone rubber covers aluminium glass bellows sheath.
Purpose of the present invention also can also realize like this:
Carry the high temperature resistant pipeline of antifreeze liquid, be characterized in that enhancement layer comprises AR aramid fibre, composite glass fiber or metal wire layer structure.
Beneficial effect of the present invention:
SEP rubber is a kind ofly with organosilicon ethylene propylene diene rubber EPDM to be carried out modification, makes the weathering resistance of EPDM and the new material that low-temperature characteristics significantly improves.This material is a kind of novel elastomer material between silicone rubber VQM and ethylene propylene diene rubber EPDM performance, it combines the advantage of two kinds of materials, overcome the shortcoming that both exist, have excellent anti-steam, boiling water and acid resistant alkali, tear-resistant, surmount the combination properties such as weatherability of silicone rubber VQM.
Adopt SEP rubber to be used for the high temperature resistant pipeline that automobile is carried antifreeze liquid, under 175 ℃ of temperature conditions, continue the 1000h air oven aging test and no abnormal, the pipeline that has fundamentally solved existing cooling system can not adapt to engine compartment long term high temperature state working environment, the technical barrier of cooling heat dissipation difference, particularly solved the thermal radiation of automobile cooling system, guarantee car engine function safe and highly efficient operation under the condition of high temperature, also satisfy the needs of novel cooling mediums such as adding ethylene glycol, water and brake fluid fully.
The invention provides a kind of high temperature resistant pipeline of carrying antifreeze liquid, not only be used for automobile, motorcycle, also can be used for fields such as boats and ships, high ferro and universal machine.
