Problems solved by technology

[0003] Conventional PU coatings used in traditional car refinish paints need to be sprayed with spray guns and air pumps, and need to be heated and dried in a paint booth. The construction time is long, the cost is high, and the environment is polluted.
Traditional UV coating requires large-scale professional UV curing equipment, which will generate high-intensity UV rays. If it is irradiated to the skin and eyes of the operator during construction, it will cause allergies, cause skin redness and acute conjunctivitis, so these problems need to be further solved

Embodiment 1

[0092] Application of a low-energy UV automotive refinish paint in the process of auto body paint repair

[0093] 1. Supplementing putty:

[0094] If the car body is sunken and damaged, use dry sandpaper 240# to polish the damaged part of the car paint, and fill it with putty. Use dry sandpaper 400# to polish the surface of the interface between the putty surface and the car paint until it is smooth and even.

[0095] 2. Make up trachoma:

[0096] Putty to fill trachoma, sandpaper marks. After drying, sand it with 600# dry sandpaper. Remove surface dust, oil stains. And wipe off moisture.

[0097] 3. Covering:

[0098] Wear protective equipment, remove the dust and oil stains on the surface being sprayed, and wipe off the water. Use a masking film to cover the area to be sprayed to prevent over-spraying.

[0099] 4. Spray primer:

[0100] Spray 1 layer of primer at a distance of 15-20 cm. (Room temperature 25 degrees Celsius, 10 minutes to dry.) After drying, polish i...

Embodiment 2

[0119] A method for using low-energy UV automotive refinish paint in the automotive lamp repair process, characterized in that: comprising the steps:

[0120] (1) Grinding

[0121] Use 320#~600#~1000# water sandpaper to polish the car lights with severe scratches, abrasions and oxidized cracks until the water flowing down is milky white, or use dry sandpaper 240#~400#~600 in sequence #~800# dry grinder to grind until frosted white, and then use 2000# water sandpaper to add water to grind until the surface is smooth and flat;

[0122] (2) cleaning

[0123] Use detergent and water to clean the dust and oil stains on the surface to be sprayed, and wipe off the water, and use a masking film to cover the parts to be sprayed to prevent over-spraying;

[0124] (3) Spraying

[0125] Wipe the surface of the car light with a dust-removing cloth, and spray one or two coats of UV car light repair paint back and forth. The spraying distance is 15-20 cm, and the interval between layers i...

Abstract

The invention provides low-energy UV-curing automotive refinishing paint. The paint comprises the following components in percentages by weight: three-functionality aliphatic polyurethane di-acrylate, ten-functionality aliphatic polyurethane hexaacrylate, trimethylolpropane trimethacrylate, ethoxylated bis phenol A dimethacrylate, 1-hydroxycyclohexyl phenyl ketone, 0-0.5% of 2-hydroxy-2-methylpropiophenone, a polyether siloxane copolymer, ethyl acetate, and 0-10% of xylene; the components are uniformly mixed in order to obtain the low-energy UV-curing automotive refinishing paint, the low-energy UV-curing automotive refinishing paint and liquefied compressed mixed gas are filled into an aerosol tank for uniformly mixing in order to obtain the aerosol low-energy UV-curing automotive refinishing paint. The paint is used for refinishing automobile body paint, repairing car lights, and the like; and the paint is environmentally friendly and nontoxic, heavy metals are not contained, and the paint can be used conveniently.

Description

technical field [0001] The invention relates to the technical field of paint processing, in particular to a low-energy UV automotive repair paint and its application and use method. Background technique [0002] UV curing technology has been industrialized since the 1970s, and has developed rapidly with the popularization of personal electronic products around the world. UV curing technology has some incomparable advantages of other conventional methods, fast curing speed (7-15 seconds), suitable for assembly line production; basically no solvent, in line with environmental protection requirements; low energy consumption; cured coating is different from the current conventional PU High hardness, high wear resistance and chemical resistance that coatings do not have. The global average annual growth rate has remained at about 10% for many years. Mainland China is the largest potential market for UV curing in the world, and it is also the region with the fastest annual growth...
