Example Embodiment

[0024] Example 1

[0025] A method for manufacturing resin felt parts for automobile engine covers. The method includes semi-finished felt blank manufacturing and parts forming and manufacturing. The specific steps are as follows:

[0026] a. Manufacturing of semi-finished felt blanks

[0027] (1) Put 50kg of cloth blooming and 25kg of commercially available ED fiber into the opener to open and mix evenly;

[0028] (2) Transport the uniformly mixed cloth and commercially available ED fibers to the air-laid machine, add 25kg of phenolic resin to the air-laid machine and continue mixing, and the mixed material will be made into a fiber web by the air-laid machine and output through the conveyor belt;

[0029] (3) Feed the fiber web into the high-temperature drying room by the conveyor belt, control the temperature of the high-temperature drying room to 160°C, and treat it at a high temperature for 2 minutes to obtain a semi-finished felt. The felt is cut and weighed according to the size....

Abstract

The invention relates to a manufacturing method of a resin felt part of an automobile engine cover. The manufacturing method comprises a semi-finished felt blank manufacturing step and a felt part molding step, and specifically, comprises mixing Bukaihua, ED fibers and a phenolic resin, preparing the mixture into a fiber mesh by an air laid machine, carrying out high-temperature treatment on the fiber mesh to obtain a semi-finished felt blank, laying a non-woven fabric on the surface of the semi-finished felt blank, putting the semi-finished felt blank with the non-woven fabric into a automobile engine cover molding mold to carry out pressing and cooling treatment, and carrying out trimming to obtain a molded resin felt part of an automobile engine cover. Compared with related products manufactured by the prior art, the resin felt part obtained by the manufacturing method has good safety, is convenient for installation, enables an engine to radiate heat uniformly, avoids machine cover overheating, and has water-proofing and oil-proofing performances.

Description

technical field [0001] The invention relates to a method for manufacturing automobile parts, in particular to a method for manufacturing resin felt parts for automobile engine covers. Background technique [0002] Resin felt parts are made by mixing cotton fiber and phenolic resin at high temperature. They are mainly installed on the engine cover of automobiles, and their main functions are sound insulation and heat insulation. The engine runs at high speed, generates heat, the temperature of the engine room rises sharply, and the engine cover of the front of the car is overheated, which will accelerate the aging of the car paint for a long time, and the paint surface will fade and crack at high temperature. Problems such as smoke from the engine cover on rainy days. Due to the flammability of its material and the location of installation, the safety requirements for this kind of parts are very high. At present, there are not many domestic enterprises that can produce part...
