Description
Technical field
The present invention relates to automobile exhaust pipe covering material technical field, particularly a kind of automobile preprocessor and blast pipe every
The soft coating member production technology of heat.
Background technology
As national Air Pollution prevention and control measure is carried out, the progressively reinforcement of energy-saving and emission-reduction measure, automobile is assembled with
Exhaust emissions post-processing purifying system, the harmful gas discharged after automobile engine burning is reacted by the combustion decomposition of cleaning system
Body, realize the purified treatment of motor vehicle exhaust emission.But whether exhaust emissions post-processing purifying system works and is and residing temperature
Degree state has direct correlation, after the delivery temperature by purifying processor carrier reaches the initiation temperature of carrier, tail gas row
Put post processing cleaning treatment system the harmful substance in vehicle exhaust could to be burnt and be decomposed, play exhaust emissions purification and make
With.
Existing automobile exhaust pipe insulation is substantially all to be protected for local, to prevent the high temperature of blast pipe from baking bad vapour
The part that the chance high temperature arranged on chassis is easily damaged or deformed, it is less demanding to the heat insulating ability of blast pipe, therefore be all first
Plate-like cotton pad is made with flameproof fabric and heat insulation foam, blast pipe is then wrapped, is fixed with clip.Basic practice is first to be vented
Tube outside bag one layer of heat preservation material, then wraps insulation material, then seam welds are arrived with thin stainless steel plate or stainless steel tube
Together and it is weldingly fixed on blast pipe.
The U of Chinese utility model patent CN 205330782 disclose a kind of insulated lorry blast pipe, including row to be wrapped
Tracheae, using blast pipe to be wrapped to rely on, one layer of heat preservation cotton pad is enclosed with outside blast pipe, one layer is wrapped up again outside insulation cotton pad
The length of the length length and insulation cotton pad of stainless steel mesh grid, wherein stainless steel mesh grid, the flange at blast pipe both ends are used
Snap ring hoop is fixed.
The content of the invention
The technical problem to be solved in the invention is to provide the soft coating member of a kind of automobile preprocessor and exhaust insulation
Production technology.
In order to solve the above technical problems, the automobile preprocessor and exhaust insulation of the present invention produce work with soft coating member
Skill, comprise the following steps,
Cut shaping：Basalt fibre felt is cut shaping as requested；
Aluminium foil is laminating：The basalt fibre felt surface glue coating of shaping will be cut, then having been coated with aluminium foil is laminating
On the basalt fibre felt of glue, flattened with roller；
Solidification：The basalt fibre felt of pressing is placed and dries 15min ± 3min in an oven, carries out curing process；
Deburring：Product is taken out in baking oven, is repaiied except redundance woollen.
Further, the solidification temperature of basalt fibre felt is 100 DEG C ± 5 DEG C in the step solidification.
Further, step burn-in test is also included after the step solidification.
Further, the laminating middle basalt fibre felt one side or double spread that will cut shaping of the step aluminium foil
Glue, then aluminium foil is laminating on the basalt fibre felt of glue is had been coated with, flattened with roller.
Further, the laminating middle use vapour-pressure type roller of the step aluminium foil flattens basalt fibre felt.
After the above method, basalt fibre felt of the invention draws high intensity height, and humidity resistance is good；It is in addition, of the invention
Basalt fibre felt thermal diffusion coefficient it is small, thermal insulation is good.
Embodiment
The automobile preprocessor and the soft coating member production technology of exhaust insulation of the present invention, comprises the following steps,
Cut shaping：Basalt fibre felt is cut shaping according to drawing requirement；
Aluminium foil is laminating：The basalt fibre felt single or double glue coating of shaping will be cut as requested, then aluminium
Paper tinsel is laminating on the basalt fibre felt of glue is had been coated with, and is flattened with vapour-pressure type roller；
Solidification：The basalt fibre felt of pressing is placed into 100 DEG C of ± 5 DEG C of baking 15min ± 3min in an oven, consolidate
Change is handled；
Deburring：Product is taken out in baking oven, is repaiied except redundance woollen.
Further, step burn-in test is also included after the step solidification.
By experimental test：
1st, before and after heatproof degradation, three kinds of tensile strength of material, basalt fibre felt>Alumina silicate felt>Chopped Strand Mat；
2nd, after thermal cycling test, substantially there is lamination in Chopped Strand Mat, and humidity resistance is poor；Basalt fibre felt and silicic acid
Aluminium felt is without significant change；
3rd, after 650 DEG C of high temperature, Chopped Strand Mat is substantially shunk, and alumina silicate felt is bent, basalt fibre felt slight bending；
4th, thermal diffusion coefficient, basalt fibre felt ＜ alumina silicate felt ＜ Chopped Strand Mats；
5th, thermal insulation, basalt fibre felt>Alumina silicate felt>Chopped Strand Mat.
Although the foregoing describing the embodiment of the present invention, those skilled in the art should be appreciated that this
Be merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the present invention principle and essence,
Protection scope of the present invention is only limited by the claims that follow.
