Problems solved by technology

[0017] (1) It is necessary to use water or organic substances as solvents, which have adverse effects on electronic products;
[0018] (2) There is waste water, waste liquid and waste gas, and post-treatment is required;
[0019] (3) The controllability of the coating thickness is poor, and it is difficult to control it to the nanometer level
[0020] In addition, the current organic coatings obtained by plasma deposition, such as fluorocarbon coatings, parylene coatings, etc., usually have a hardness of HB-2H, which is easy to cause damage under touch and scratch conditions, reducing the service life

Abstract

The invention provides a preparation method for a high-insulation hard nanometer protection coating of a composite structure, belonging to the field of plasma technology. According to the method, a reaction cavity is vacuumized and inert gas is introduced to allow a substrate to move, so organosilicon monomers with low dipole moment and high chemical inertia are screened out; the free volume and compactness of a coating are regulated and controlled through multifunctionality monomers, so the coating is allowed to have insulating properties and excellent protection performance and wear resistance at the same time; and an organosilicon coating is deposited on the coating with high insulating properties, and surface hard treatment is carried out so as to form a hard coating with a compact structure. The high-insulation hard nanometer protection coating provided by the invention has more excellent protection performance, insulating properties and wear resistance compared with conventionalcoatings such as parylene under the condition of same thickness. The preparation method provided by the invention overcomes the problems of poor wear resistance, too great thickness, low production efficiency and the like of conventional parylene coatings; and through hard treatment, a composite wear-resistant silica structure is increased in the coating, and the hardness and wear resistance of the coating are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of plasma chemical vapor deposition, and in particular relates to a preparation method of a nano protective coating. Background technique [0002] Anti-mold, anti-humidity, and anti-salt mist (referred to as three antis) are important problems that need to be solved during the storage, transportation and use of electronic devices. Mold, salt spray and humidity often cause electronic devices to fail due to short circuits. In addition, since many electronic products in daily life are easily touched and scratched during use, they are damaged. Therefore, for the protective coating used in the electronics industry, in addition to having excellent "three-proof" performance, it must also have good insulation and good wear resistance. [0003] At present, the use of protective coatings to protect electronic products is an effective way to improve the service life of electronic products. There are generally two me...
