Abstract
The present invention relates to the protecting and supporting cushion, i.e., one non-metallic liner to replace metal one, for vehicle catalytic converter. The liner is manufactured by using ceramic fiber cotton and phlogopite as main material and through crushing, stoving, mixing, adding supplementary material and latex while stirring, vacuum pumping, drying and forming.
Description
This invention relates to a kind of vehicle catalytic converter liner, especially non-metallic liner.
It is to have the ceramic-fibre and the elastomeric material that the phlogopite sheet with thermal expansion character combines together according to a certain ratio of high temperature durability, performance-oriented bed knife can be provided in wide range of temperatures that this invention relates to.It plays in vehicle catalytic converter and does not add the critical material that lacks.
The vehicle catalytic converter liner generally all uses metallic material to be made in the market, and its carrier is difficult fixing, carrier and housing have certain space, are easy to generate vibration, and leak tightness is poor, noise is big, thereby influences the pollution of catalytic convertor service life and environment.
The objective of the invention is to solve problems such as catalytic convertor in-to-in vibration damping, sealing, heat insulation, noise reduction, thus alternative metals liner fully.
The present invention is achieved in that the ceramic-fibre that will have high temperature durability combines together in proportion with the phlogopite sheet with thermal expansivity; Go out resilient product through specific explained hereafter.At first the ceramic-fibre cotton is put into the hydraulic propeller pulper, concentration of aqueous solution is controlled at 3%, and machine size degradation 15 minutes is transported in the stock tank of hydraulic propeller through stock pump then, and stock tank is transported to through stock pump and mixes fine grinding in the grinding machine,
Make the ceramic-fibre diameter reach 0.5 μ, again through centrifuge dewatering, and then oven dry, the baking temperature is 120 ℃, work-hours is 20 minutes.Oven dry finishes, and fiber is standby.Again phlogopite tablet raw material crushing screening particle diameter is reached 8～40 orders, add the swelling agent chemical treatment again, filtration drying is standby.Then above both standby raw materials being put into mixer by proportioning (40/50 mass parts respectively) mixes, treat to mix fully, add latex agent and auxiliary material again, stirred 10 minutes, be transported to " horizontal belt manufacture paper with pulp machine " through vacuumizing extrusion forming through stock pump then, drying equipment drying again, drying finishes and is cut into required specification product again.
Advantage of the present invention is: substitute used metal gasket 1.; 2. the non-metallic liner bed knife that can provide vehicle catalytic converter to contain the height performance in wide range of temperature makes itself and housing keep positive pressure forever, thereby prolongs the service life of catalytic convertor.3. excellent sealing performance and soundproof effect prevent that effectively gas from leaking from ceramic monolith and body clearance, can improve the noise control of exhaust system simultaneously.4. good heat-proof quality can reduce the catalytic convertor case temperature, prevent peripheral damage parts.
The present invention is further narration in conjunction with the embodiments:
1. earlier the cotton raw material of ceramic-fibre is put into the hydrabrusher size degradation, become dispersed by original bulk cellucotton, be transported to through stock pump again and mix fine grinding in the grinding machine, the diameter of ceramic-fibre cotton is reduced to below 0.5 μ, then through centrifuge dewatering, oven dry, temperature required 120 ℃, the time is 20 minutes, and the oven dry back is standby.2. make its particle diameter reach 8～40 orders phlogopite tablet raw material crushing screening again, the hydrogen peroxide chemical treatment through 10% was soaked 20 minutes, carried out filtration drying, and baking temperature is controlled at about 120 ℃.The half-blank of ceramic-fibre cotton and the half-blank of phlogopite sheet are mixed stirring (their proportionings are 40/50 mass parts respectively),, add latex agent (mass parts 10) again, stirred 30 minutes until stirring.Be transported on the horizontal belt machine of manufacturing paper with pulp into through stock pump then and vacuumize moulding, pressurization 6kpa carries out drying again, and temperature is controlled at 120 ℃, and drying time is 10 minutes, and the back integer is cut out finished product again.
