Embodiment 1

[0025] A method for manufacturing a resin felt part for an automobile engine cover, the method comprises the manufacture of a semi-finished felt blank and the molding of the part, and the specific steps are as follows:

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

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

[0028] (2) The uniformly mixed cloth flower and commercially available ED fibers are transported to the air-laid machine, and 25kg of phenolic resin is added thereto to continue mixing, and the mixed material is made into a fiber web through the air-laid machine and is output by a conveyor belt;

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

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...
