Problems solved by technology

[0002] The current car stickers can only play a decorative role. When the car is driving at night or in rain, fog, tunnels and other environments, sometimes the environment is very dark and the lights are not eye-catching enough, which may easily cause traffic accidents. There is an internship logo on the rear of the car, but it is not eye-catching at night, and it is not easy to see. In addition, ordinary car stickers are not easy to tear off, and it is inconvenient to clean the car.
In addition, the containers on the container trucks are in international circulation, and the ones used now are generally disposable self-adhesive reflective stickers, which cannot be reused, and the cost of use is high

Embodiment Construction

[0019] A method for preparing a reflective and heat-insulating film for a vehicle roof, comprising the following specific steps:

[0020] (1) Bead planting:

[0021] Coat the acrylic resin adhesive on the PET film, and after drying in an oven at 115°C, adhere the magnetic glass beads to the surface of the adhesive layer, and the depth of the glass beads into the adhesive layer is 1 / 2 of the diameter of the glass beads;

[0022] (2) Preparation of titanium dioxide sol:

[0023] Slowly add 2 parts of deionized water dropwise to 38 parts of absolute ethanol while stirring, and then slowly add 6 parts of diethanolamine dropwise while ultrasonicating, and then slowly add 15 parts of titanic acid dropwise Tetrabutyl ester, after adding dropwise, ultrasonically oscillate for 1 hour, and let it stand for 24 hours to obtain a titanium dioxide sol;

[0024] (3) Coating:

[0025] Use an electrostatic spray device for titanium dioxide coating, place the resin substrate after bead plant...

Abstract

The invention discloses a method for preparing a light-reflecting and heat-insulating film for a vehicle roof. Magnetic glass beads are used as a raw material, certain magnetic performance is given to a product, and replacement and the cleaning of a vehicle body are facilitated. Then an electrostatic spraying method is used to deposit a TiO2 thin film on the surface of a resin film substrate which is subjected to bead planting, a base film which is plated with the TiO2 thin film has good heat insulating property and flexibility and can be bent arbitrarily in a bearable range, and convenience is brought to the use and collection of the product. Then the retro-reflecting coefficient of the product is greatly improved after spraying and aluminum plating, the product has an excellent reflective effect and plays an excellent conspicuous warning role, and a purpose of reducing the temperature in a vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of reflective materials, in particular to a method for preparing a reflective heat-insulating film for a vehicle roof. Background technique [0002] The current car stickers can only play a decorative role. When the car is driving at night or in rain, fog, tunnels and other environments, sometimes the environment is very dark and the lights are not eye-catching enough, which may easily cause traffic accidents. The practice logo is placed on the rear of the car, but it is not eye-catching at night and is not easy to see. In addition, ordinary car stickers are not easy to tear off, and it is inconvenient to clean the car. In addition, the containers on the container trucks are in international circulation, and the ones used now are generally disposable self-adhesive reflective stickers, which cannot be reused and are expensive to use. Contents of the invention [0003] The invention provides a method for ...
