preparation example Construction

[0032] The invention provides a method for preparing a hydrophilic anti-fog film with wear resistance and frost resistance, comprising the following steps:

[0033] (1) Prepare a reactant solution with a certain concentration;

[0034] (2) Spin coating and dry.

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with specific embodiments.

[0036] Step 1: Prepare a certain concentration of reactant solution

[0037] In one embodiment, this step can be specifically carried out as follows: First, put the glass slide in a beaker and pass through acetone, absolute ethanol, and deionized water for 15 minutes of ultrasonication. After the ultrasonication is completed, put it in a 60°C oven for drying, and cool it for later use. Prepare 0.1-2 mg / mL cellulose solution, 1-10 mg / mL iron ion solution and 250-2000 mg / mL polyacrylic acid solution, ...

Embodiment 1

[0046] In this embodiment, a hydrophilic anti-fog film with wear resistance and frost resistance is prepared according to the following steps:

[0047] Step 1. Prepare a certain concentration of reactant solution

[0048] Put the glass slice in a beaker and pass it through acetone, absolute ethanol, and deionized water for 15 min in order to sonicate. After the sonication, put it in a 60 ℃ oven to dry, and cool it for later use. Prepare 0.2 mg / mL cellulose solution, 1.2 mg / mL iron ion solution and 250 mg / mL polyacrylic acid solution, mix them in a volume ratio of 1:2:1, mix them evenly with a mixer, and let stand spare;

[0049] Step 2. Spin coating and drying

[0050] The cleaned glass sheet was treated with oxygen plasma for 2.0 min, and then the mixed solution prepared in step 1 was spin-coated on the glass sheet at a spin-coating speed of 1000 r / min for 5 s, and then placed at 90 °C Dry in an oven for 3 h.

Embodiment 2

[0052] In this embodiment, a hydrophilic anti-fog film with wear resistance and frost resistance is prepared according to the following steps:

[0053] Step 1. Prepare a certain concentration of reactant solution

[0054] Put the glass slice in a beaker and pass it through acetone, absolute ethanol, and deionized water for 15 min in order to sonicate. After the sonication, put it in a 60 ℃ oven to dry, and cool it for later use. Prepare cellulose solution of 1.0 mg / mL, iron ion solution of 2.5 mg / mL and polyacrylic acid solution of 500 mg / mL, and mix them in a volume ratio of 1:2:1, mix them evenly with a mixer, and let stand spare;

[0055] Step 2. Spin coating and drying

[0056] The cleaned glass sheet was treated with oxygen plasma for 3.0 min, and then the mixed solution prepared in step 1 was spin-coated on the glass sheet at a spin-coating speed of 700 r / min and a spin-coating time of 20 s, and then placed at 100 Dry in an oven at ℃ for 4 h.

Abstract

The invention discloses a preparation method of a hydrophilic anti-fog film with wear resistance and frost resistance. The method comprises the following steps of: (1) preparing a cellulose solution,a metal iron ion cross-linking agent and a polyacrylic acid solution with certain concentrations; and (2) mixing and oscillating a certain volume of the three solutions, spin-coating the three solutions on a cleaned glass sheet by using a spin coater, taking out the glass sheet after spin-coating is finished, and drying the glass sheet to obtain the glass with the anti-fog performance. According to the method, the hydrophilic anti-fog film with wear resistance and frost resistance is prepared by adopting a simple spin-coating method, and the method has the advantages of a simple process, easiness in operation, controllable reaction conditions, wide sources of raw materials and the like, does not pollute the environment, has an excellent anti-fog effect and good mechanical properties, and does not influence the light transmittance of the glass.

Description

technical field [0001] The invention relates to a preparation method for constructing a hydrophilic anti-fog film with wear-resistant and frost-resistant properties on the surface of glass. Background technique [0002] Glass is very common in people's daily life and production, such as car windshields, rearview mirrors, bathroom mirrors, windows and solar panels, etc., and has a wide range of uses. However, under certain temperature and humidity conditions, water vapor will condense together to form tiny water droplets, which is prone to fogging on the glass surface. Due to the existence of small water droplets, it will cause light refraction and reflection. In some cases, fogging will have a certain impact on people's life and production. For example, it will affect the sight of car drivers, making it impossible to see objects in front of them through the glass, which poses a great traffic safety hazard. [0003] There are two main anti-fog methods currently being studied...
