Problems solved by technology

However, this design is not beautiful enough, bulky, and for the manufacturer, it increases the cost of design and molds, and it is easy to lose waterproofness due to structural damage, such as cracks or missing blocks.
[0003] However, the existing waterproof coatings can only be applied to construction, home furnishing and other fields, and it is difficult to apply to electronic products such as mobile phones and PCs. Moreover, the existing coatings have certain toxic effects and are not environmentally friendly.

Embodiment 1

[0025] First, add paraffin wax to absolute ethanol, heat to 50°C and stir until the wax is completely dissolved to form a paraffin wax solution; then add deionized water to the paraffin wax solution and quickly mix until uniform to prepare hydrophobic paraffin wax.

[0026] Then, 550g of acrylic resin, 200g of lotus leaf hydrophobic agent, 20g of dispersant (BYK5040) and 30g of defoamer (YH-203) were stirred with a high-speed disperser at a speed of 500r / min at room temperature. for 10 min; then add 100 g of nano-hydrophobic silica and stir for 1 h at a speed of 2000 r / min. Finally, 100 g of hydrophobic paraffin was added and stirred at 2500 r / min for 2 hours to obtain the finished product.

Embodiment 2

[0028] First, add paraffin wax to absolute ethanol, heat to 45°C and stir until the wax is completely dissolved to form a paraffin wax solution; then add deionized water to the paraffin wax solution and quickly mix until uniform to prepare hydrophobic paraffin wax.

[0029] Then, 500g of acrylic resin, 180g of lotus leaf hydrophobic agent, 10g of dispersant (BYK5027) and 10g of defoamer (YH-203) were stirred with a high-speed disperser at a speed of 500r / min at room temperature. for 10 minutes; then add 150g of nano-hydrophobic silicon dioxide and stir for 1 hour at a speed of 2000r / min; finally add 150g of hydrophobic paraffin and stir for 2 hours at 2500r / min to obtain the finished product.

Embodiment 3

[0031] First, add paraffin to absolute ethanol, heat to 55°C and stir until the wax is completely dissolved to form a paraffin solution; then add deionized water to the paraffin solution and quickly mix until uniform to prepare hydrophobic paraffin.

[0032] Then, 400g of acrylic resin, 300g of lotus leaf hydrophobic agent, 20g of dispersant (BYK5027) and 20g of defoamer (YH-203) were stirred with a high-speed disperser at a speed of 500r / min at room temperature. for 10 minutes; then add 140g of nano-hydrophobic silicon dioxide and stir for 1 hour at a speed of 2000r / min; finally add 120g of hydrophobic paraffin and stir for 2 hours at 2500r / min to obtain the finished product.

Abstract

The invention provides a waterproof coating, which includes a film-forming agent, a hydrophobic agent, hydrophobic nano silicon dioxide and hydrophobic paraffin. The waterproof paint provided by the present invention is a colorless and transparent coating material with waterproof function, which can be directly coated on the circuit board or shell of the mobile phone to achieve waterproof and dustproof effects. The preparation process is simple and the operation is simple and convenient, which reduces the production cost of mobile phone production. Since the coating is directly coated on the circuit board, it has excellent waterproof performance without changing the original structural design of the mobile phone.

Description

technical field [0001] The invention relates to the field of waterproofing, in particular to a waterproof coating. Background technique [0002] With the development of society, the advancement of science and technology, and the gradual expansion of the mobile phone market, the performance requirements of consumers for mobile phones are also constantly improving. While mobile phones are becoming more functional and intelligent, they are beginning to pursue humanization, such as waterproofing. Due to the continuous development of functionalization and intelligence on mobile phones, consumers can play with mobile phones anytime and anywhere. They use mobile phones when driving, walking, eating, working, and even when going to the toilet and bathing. However, when taking a shower or going to the toilet, the mobile phone is accidentally dropped into the toilet or sink, so that the mobile phone will enter the water, causing the mobile phone to be short-circuited and broken.
