Abstract

The invention relates to the field of super-hydrophobic materials, in particular to a multi-functional-group purine compound, a super-hydrophobic material for car paint and a preparation method thereof. By using the multi-functional-group purine compound to modify a nano material, adhesiveness of a super-hydrophobic nano material during application can be improved greatly; the compound has purinegroups, so that durability of the super-hydrophobic material can be improved; silicyl of the compound is in condensation with hydroxyl of a nano material under catalysis of acid or alkali to form a hydrophobic material, so that according to the above property, the compound can be used to modify a nano oxide material to obtain the super-hydrophobic material, and adhesiveness and durability of the super-hydrophobic material are improved. In addition, hydroxyl can also be formed after silicyl is hydrolyzed, and silicyl can also be in condensation with hydroxyl of a substrate material face, so that firmness of the compound adhered on glass is further improved.

Description

technical field [0001] The invention relates to the field of superhydrophobic materials, in particular to a multifunctional purine compound and a superhydrophobic material for car paint and a preparation method thereof. Background technique [0002] According to incomplete statistics, the number of locomotives in the world has reached more than one billion by 2017, and it is still increasing at a rate of 3%-5% every year. my country's car ownership is also close to 200 million, and it is still increasing at an annual rate of 10%. While cars bring convenience to life, the problems of water resource consumption and environmental pollution caused by car washing are becoming increasingly serious. Therefore, the no-cleaning self-cleaning of the car paint surface has become a problem of increasing concern. [0003] Superhydrophobic means that the contact angle between the surface of the material and water is >150°. This material has good hydrophobicity, and can realize variou...
