Problems solved by technology

Conventional crystal plating liquid generally has the problem of long curing time
[0003] In addition, the conventional crystal plating solution can only protect the car paint, but has no reflective effect at night. If you want the vehicle to have a reflective effect at night, you must attach reflective strips, and reflective strips can only be attached to specific positions such as corners. Usually only a few centimeters, the small area is not eye-catching at night

Embodiment 1

[0025] At room temperature, add 35 g of dimethyl polysilazane (molecular weight is about 1000) and glass microspheres (white, uncoated, 300 mesh, refractive index 1.93) 15 g to a beaker with 39 g of toluene in a fume hood , 3 g of γ-(methacryloyloxy)propyltrimethoxysilane, and 8 g of polymethylsiloxane were stirred at 200 r / min for 20 minutes to obtain a reflective crystal plating liquid for vehicles.

Embodiment 2

[0027] At room temperature, in a fume hood, add 15 g of perhydropolysilazane (molecular weight is about 6000) and glass beads (white, uncoated, 800 mesh, refractive index 1.93 ) 5g, N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane 0.3g, heptadecafluorodecyltriethoxysilane 0.5g, stirred at 200r / min for 20 minutes to obtain a Crystal plating solution for reflective vehicles.

Embodiment 3

[0029] At room temperature, in a fume hood, add 50 g of methylhydropolysilazane (molecular weight about 1500) and glass beads (white, uncoated, 1500 mesh, refractive index 2.20) to a beaker with 21 g of cyclohexane in a fume hood. 25g, (N-perfluorooctylsulfonyl)-aminopropyltriethoxysilane 1g, tridecafluorooctyltriethoxysilane 3g, stirred at 200r / min for 20 minutes to obtain a reflective car With plating solution.

Abstract

The invention relates to a reflective crystal plating liquid for vehicles and a preparation method thereof, belonging to the technical field of vehicle maintenance. Based on the overall mass of the crystal plating liquid as 100%, the components and their mass percentages are as follows: polysilazane 1%-60%; glass microspheres 1%-30%; silane coupling agent 0.1%-5 %; Hydrophobic agent 0.1%-10%, the balance is an organic solvent; the glass microspheres added in the crystal plating liquid can not only play a conventional reflective effect, in addition, because the main component of the glass microspheres is silicon dioxide, it is different from the The composition of crystal plating after solidification is basically the same, so it can also play the role of crystal nucleus, inducing other components in the crystal plating liquid to solidify rapidly around it, so that the glass beads and other components in the crystal plating liquid are closely combined, and the curing speed can be improved. More than 20%.

Description

technical field [0001] The invention relates to a reflective crystal plating liquid for vehicles and a preparation method thereof, belonging to the technical field of vehicle maintenance. Background technique [0002] Crystal plating can form a bright and hydrophobic high-hardness inorganic film on the surface of the car, achieving multiple functions such as self-cleaning, anti-scratch, and anti-aging and corrosion of car paint. It has become the latest paint beauty method to replace coating and waxing. The main film-forming component of the crystal plating solution is polysilazane polymer compound, which is oxidized in the air and gradually forms a silicon dioxide layer. At the same time, adding a hydrophobic agent can improve the hydrophobic performance of the crystal-coated film, making it difficult for sewage to adhere and play a role in self-cleaning. Adding a coupling agent can make the crystal plating film and the car paint tightly combined and not easy to fall off. ...
