Abstract
The invention discloses a processing method for paint for automobile hub renovation. The required paint for the automobile hub renovation is obtained by uniformly mixing all components according to a ratio and then carrying out screw extrusion treatment. According to the processing method for the paint for the automobile hub renovation, the defects of high possibility in caking, high difficulty in spraying and poor environmental protection performance in the prior art are overcome, and the advantages of low possibility in caking, high convenience in spraying and good environmental protection performance are realized.
Description
Technical field
The present invention relates to automobile technical field, particularly, relate to a kind of working method of automotive hub renovation coating.
Background technology
Wheel hub, be in doughnut centered by axle for the cylindrical metal parts of support tire, generally, being exactly the position that wheel center installs axletree, is the important spare part connecting brake drum, wheel disc and semiaxis.
Powder coating is according to its good feature of environmental protection and the fast development in parts industry gradually of excellent corrosion resistance nature, and the application especially on automobile aluminum wheel hub is particularly extensive.
Generally traditional low temperature cured powder coating, add catalyst method by tradition, although solve low-temperature curing, due to powder, reactive behavior is too fast in the curing process, too responsive to temperature, when being applied to the spraying of aluminium wheel, levelling property is bad, does not possess splendid levelling property, the mirror effect requirement of aluminium wheels application cannot be met, the general second-order transition temperature of this type of powder coating is lower in addition, easily lumps, affect spraying application in transport and use procedure.
Realizing in process of the present invention, contriver to find in prior art at least to exist the defects such as the large and feature of environmental protection of easily caking, spraying difficulty is poor.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of working method of automotive hub renovation coating, to realize prevented from caking, to spray convenient and that the feature of environmental protection is good advantage.
For achieving the above object, the technical solution used in the present invention is: a kind of working method of automotive hub renovation coating, comprising:
(1) by each component of following parts by weight proportioning:
Hexanodioic acid: 6 parts;
New pentane diacid: 7 parts;
Cyclohexanedimethanol: 10 parts;
TriMethylolPropane(TMP): 10.5 parts;
