Abstract
The invention belongs to the field of automobile spare parts, and particularly relates to a polyethylene material spraying method and application of the polyethylene material spraying method. The polyethylene material spraying method comprises the first step of grinding, the second step of primer spraying, the third step of varnish spraying and the fourth step of colored paint spraying. The invention further provides the application of using the polyethylene material spraying method for surface spraying of a polyethylene material of a hollow structure. According to the polyethylene material spraying method and the application of the polyethylene material spraying method, after grinding, primer spraying, varnish spraying and colored paint spraying are sequentially carried out the polyethylene material to be sprayed, the colored paint and varnish paint film cross test in the China National Standard GB / T 9286-1998 is adopted for the obtained product, and according to the results of the test, the surface adhesive force of the coating meets the requirements; and meanwhile, the surface of the product is flat and smooth after painting, and good in texture. The technical defect that in the prior art, the spraying effect of a hollow blow molding polyethylene automobile protection bar is poor is overcome.
Description
technical field [0001] The invention belongs to the field of auto parts, in particular to a polyethylene material spraying method and application thereof. Background technique [0002] The front and rear ends of the car are usually equipped with a bumper, which not only has a decorative function, but more importantly: the bumper can also absorb and ease external impact, protect the body, and protect the safety of the body and occupants. Now there are usually polyethylene hollow blow molding car bumpers and traditional acrylonitrile-butadiene-styrene copolymer hollow blow molding car bumpers on the market. Compared with the traditional acrylonitrile-butadiene-styrene copolymer hollow blow molding protective bumper, polyethylene hollow blow molding has the following advantages: 1. The density of polyethylene material is 0.94g / cm 3 , the density of acrylonitrile-butadiene-styrene copolymer is 1.05g / cm 3 , under the same volume, the quality of the former product is lighter; 2....
