Manufacture method of fan blade of automobile engine

Abstract

The invention discloses a manufacture method of a fan blade of an automobile engine. Raw materials comprise the following components in parts by weight: 1 to 2 parts of an ultraviolet light absorber,75 to 85 parts of polypropylene, 8 to 12 parts of ethylene-octylene copolymer elastomer POE, 5 to 10 parts of polyamide, 1 to 3 parts of fine silicon dioxide, 3 to 5 parts of an organosilicon coupler,20 to 25 parts of alkali-free short glass fiber, 1 to 2 parts of a beta nucleating agent, 1 to 5 parts of an antioxidant, and 1 to 3 parts of dilauryl thiodipropionate. The method adopts polyamide plastic which has the advantages of good toughness and not easiness in bending, and low carbon alloy steel has low cold shortness tendency, notch and aging sensitivity, and good capability for resistingcorrosion of air oxide and rainwater, so that the strength and abrasion performance of the fan blade are improved, and the blade is light and thin, and has excellent strength.

Description

technical field [0001] The invention relates to the technical field of manufacturing automobile parts, in particular to a method for manufacturing fan blades of automobile engines. Background technique [0002] At present, engineers and technicians from all over the world put their professional products in the first place to meet the research and development of energy-saving and environmental protection. During the use of automobile cooling fan blades, many problems occur, such as loud noise, easy damage, and even fan blade breakage. Problem, therefore, in order to solve the above problem, the present invention discloses a car cooling fan blade, which adopts polyamide plastic, which has the advantages of light weight, good toughness, and is not easy to break, etc., while low-carbon alloy steel has a lower tendency to be cold and brittle, notch and Sensitivity to aging, and good corrosion resistance to air oxides and rainwater, thus improving the strength and wear resistance ...
