Embodiment 1

[0025] Add 0.05g of film-forming agent (high molecular polymer) of n=2300, 499.45g of deionized water into a three-necked flask with mechanical stirring, thermometer and reflux condenser in 500ml successively, heat to 70°C, stir until dissolved, and cool to room temperature, then add R=CH 3 NHCH 2 -, m=800 0.5 g of hydrophilic silicone oil, mechanically stirred for 20 minutes to obtain the demister of the present invention.

[0026] Through tests, the effective demisting action time of the defogging agent of the present invention is more than three weeks.

Embodiment 2

[0028] In a 500ml three-necked flask with mechanical stirring, thermometer and reflux condenser inserted in sequence, add 0.1g of high molecular polymer with n=3000, 498.9g of deionized water, heat to 70°C, stir until dissolved, cool to room temperature, and then add R =C 4 h 9 O(C 2 h 4 O) z CH 2 (CHCH 2 )O-, m=1000, z=10 1g of hydrophilic silicone oil, mechanically stirred for 20 minutes to obtain the demister of the present invention.

[0029] Through tests, the effective demisting action time of the defogging agent of the present invention is more than three weeks.

Embodiment 3

[0031] In a 500ml three-necked flask with mechanical stirring, thermometer and reflux condenser inserted in sequence, add 0.2g of high molecular polymer with n=1500, 498.8g of deionized water, heat to 70°C, stir until dissolved, cool to room temperature, and then add R =CH 3 NHCH 2 -, m=900 1g of hydrophilic silicone oil, mechanically stirred for 20 minutes to obtain the demister of the present invention.

[0032] Through tests, the effective demisting action time of the defogging agent of the present invention is more than three weeks.

Abstract

The invention relates to a normal-temperature glass fog remover. The fog remover is prepared by mixing and stirring the following raw materials in percentage by weight: 0.05-0.5% of hydrophilic silicone oil, 0.01-0.05% of film forming agent and the balance of diluent. The fog remover provided by the invention is suitable for demisting the front and rear windshields and rearview of an automobile aswell as the lenses of spectacles; the high molecular polymer and hydrophilic silicone oil are nontoxic, and no volatile organic maters are adopted; the fog remover has the characteristics of lastingdemisting effect, environmental friendliness, harmlessness to a driver and passengers in the automobile as well as the wearer of the spectacles, etc.

Description

technical field [0001] The invention belongs to the technical field of defoggers, and in particular relates to a normal temperature type glass defogger. Background technique [0002] In an environment with high humidity and uneven heat and cold inside and outside, a layer of water mist is easily formed on the inner surface of the glass surface, resulting in poor transparency of the glass. A common phenomenon is that on rainy days with high humidity, the windshield of a car often forms a layer of fog on the surface of the glass inside the car, which affects the driver's sight and causes great potential harm to traffic. The various far and near-sighted spectacle lenses and swimming glasses that people wear are also prone to fogging. Once fog exists, it will affect people's sight, thereby affecting safety. [0003] Now cars must enforce national defogging and defrosting system standards. The standard mainly stipulates the air-conditioning system blowing time for automobiles. ...
