Description

Technical Field

[0001] The invention relates to the technical field of fine chemicals, and relates to an automobile wax spray aerosol, an automobile wax spray product, a preparation method and an application. Background Art

[0002] Thanks to the growing number of cars, the market for car maintenance products has been further expanded. As cars are exposed to the outdoor environment for a long time and are affected by ultraviolet rays, acid rain, sand and gravel, salt corrosion, shellac, bird droppings, exhaust oil pollution, etc., the car paint will age prematurely, turn yellow, and accumulate dirt. In addition, the oxidation of the car paint surface will gradually cause the car paint to age and turn yellow, fall off and rust. Unprofessional maintenance and abuse of products may also cause scratches, damage, corrosion and aging of the paint surface. Car paint maintenance can effectively prevent car aging. Paint maintenance products have also emerged in an endless stream with the development of the market. The more common paint maintenance products include crystal plating liquid, car solid wax, rapid coating agent, etc., and car polishing and waxing are the main ways to maintain the car paint surface.

[0003] The traditional waxing process of automobile solid wax is time-consuming, generally requiring 2 to 3 hours of construction time. The surface of the car paint needs to be thoroughly cleaned and dried before construction. After the paint surface treatment is completed, a sponge should be dipped in solid car wax and evenly applied to the surface of the car paint in circles. Wait for a few minutes for the car wax to dry thoroughly, and then wipe the excess car wax with a delicate and soft towel until the car paint is bright and a layer of wax film is evenly formed. Some unskilled novice technicians are prone to improper construction and coating, which can easily cause excessive car wax coating, resulting in waste and difficulty in wiping after drying, leaving a layer of white marks on the car paint. Although the construction of rapid coating agents is relatively convenient, rapid coating agents only perform simple hydrophobic treatment on the car paint, and do not have a good car paint protection effect. There are even cases of corrosion and whitening caused by spraying on plated parts and rubber strips. Many rapid coating liquids are unevenly dispersed, resulting in uneven film formation after spraying. If accidentally sprayed on the glass, it will cause wiper beating, glass fogging and other undesirable phenomena, and the brightness of the film formed by the rapid coating agent is poor.
