Problems solved by technology

Looking at the current commercially available car waxes from the perspective of the demand side, their performance still needs to be strengthened and improved. The function is that when coated on the surface of the car paint, it can fill up the unevenness on the paint to achieve the purpose of brightness and protection. Although some products use nanotechnology and cause a water drop effect with a contact angle of about 106 degrees, the water drop is fluid not as good as expected

Abstract

The invention provides a composition used for material surface treatment, and a material with hydrophobic surface and a hydrophobic film which are prepared with the composition. The material surface treatment composition comprises wax, silicon oil, hydrocarbon mixture oil from C6 to C30, nano powder and resin; making use of the nano-powder of the composition, the modified material surface can be endowed with the property of low detention resistance against water caused by low surface energy and coarseness.

Description

technical field [0001] The invention provides a material surface treatment composition, and further, the invention also provides a material surface hydrophobic film containing the material surface treatment composition. Background technique [0002] Surface treatment science is an important subject in material science. Through surface treatment, the surface properties of materials can be changed, making it applicable to other fields. Surface treatment can be divided into permanent and temporary surface treatment. A representative example of permanent surface treatment is electroplating, which deposits a metal or alloy film on the surface of a material through an electrochemical method to produce a long-term property change on the surface of the material. However, this type of processing requires specific equipment to be carried out, and it is not easy for ordinary people to operate. [0003] Temporary surface treatment refers to the formation of a film on the surface of th...
