Description of the embodiments
The present invention will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention provides a technical scheme that: the wear-resistant coating consists of the following raw materials in percentage by mass: 20-25% of polytetrafluoroethylene and 5-10% of phenolic resin.
Polytetrafluoroethylene is widely used in various fields including coating preparation processes, in which polytetrafluoroethylene is used to enhance lubricity and wear resistance of a coating so that it can withstand high stress conditions occurring when a saw blade cuts a hard material, due to its unique properties including high durability, low friction and excellent lubricity.
Phenolic resins, in turn, are thermosetting resins having high strength, toughness and durability, and are often used in a variety of coating applications because of their ability to adhere well to a variety of surfaces and provide excellent chemical resistance, where they serve to enhance the durability and corrosion resistance of the coating, making them better resistant to harsh environmental conditions and the corrosive action of moisture or other corrosive substances.
Thus, by combining the polytetrafluoroethylene with phenolic resin, the addition to the coating preparation results in 1. Improved lubricity and wear resistance, 2. Increased durability, 3. Improved cutting performance.
Abrasion resistance: the lubricity and wear resistance of the coating may be enhanced to withstand the high stress conditions that occur when cutting hard materials with a saw blade.
Durability: the durability and corrosion resistance of the coating are improved, so that the coating can better bear severe environmental conditions and the corrosion action of other corrosive substances.
Cutting performance: improved lubricity and wear resistance, reduced need for frequent maintenance, and improved cutting performance.
3-15% of organic polymer, wherein the organic polymer additive is polyamide imide and graphite, the polyamide imide is 7-15%, and the graphite is 3-7%.
Organic polymers are polymeric compounds formed by covalent bonding of a number of identical or different monomer molecules. They have many excellent properties such as high strength, high toughness, heat resistance, corrosion resistance, etc., and thus are widely used in various fields including coating preparation processes, and thus mainly serve three functions in the coating preparation process, 1. Improvement of durability, 2. Improvement of wear resistance, 3. Improvement of chemical resistance.
However, in the preparation process of the organic polymer in the present invention, two kinds of the organic polymer are classified into polyamideimide and graphite:
the polyamide imide has the characteristics of high strength, flexibility and heat resistance, so that the polyamide imide is an excellent choice in the preparation of the coating, and mainly plays a role in improving the wear resistance and durability of the coating, so that the polyamide imide can ensure the service effect under severe environment and the service life.
And graphite has high conductivity, high hardness and thermal stability, and when the graphite is applied to the wear-resistant coating, the electrical performance of the coating can be improved by adding the graphite with proper mass percent, and the effect of ensuring heat dissipation is achieved.
Illustrating: in the production process of microelectronic products or precision optical elements, a high-speed dicing machine is needed, wherein the high-speed dicing machine, a main shaft, a flange disc and a saw blade are used as an anode, a workbench is used as a cathode, the saw blade rotating at high speed moves towards the workbench along with the movement of the main shaft, when the saw blade contacts the workbench, the anode and the cathode together with current generation are considered to be the peaks of the saw blade in the vertical direction, the purpose that the workpiece can be cut through and the saw blade can not be cut to the workbench is achieved, and the situation that the cutting saw blade requires higher conductivity in the tool setting process is guaranteed, and the current generation is convenient for subsequent confirmation of the position of the saw blade is guaranteed.
10% -15% of molybdenum disulfide, wherein the inorganic compound is molybdenum disulfide, and the compound number of the molybdenum disulfide is Cas1317-33-5.
Molybdenum disulfide is an inorganic material, which has advantages of high strength, high corrosion resistance, and excellent heat resistance. The molybdenum disulfide is used for enhancing the corrosion resistance and the heat resistance of the coating when the coating is manufactured, so that the coating can bear severe environmental conditions and the durability of the saw blade is improved.
The high-temperature-resistant effect is mainly achieved in a high-temperature environment, such as woodworking or metal cutting, better heat resistance is provided for the coating, and molybdenum disulfide is known to be high in corrosion resistance, so that moisture and other corrosive substances can be effectively blocked, the coating is more comfortable to use in a severe or humid environment, and meanwhile, the coating has a low friction coefficient and hardness, and meets the use requirements under the condition of high stress.
Further, the solvent is 4% -15%, the solvent comprises butanol and propylene glycol methyl ether acetate, the butanol is 4% -5%, and the propylene glycol methyl ether acetate is 8% -15%.
The butanol and the propylene glycol methyl ether acetate are both organic solvents, and have high purity and low toxicity, and when the butanol and the propylene glycol methyl ether acetate are added into the coating, the coating performance can be improved, particularly the fluidity and the distribution of the coating can be improved, the coating is easier to apply, potential defects or flaws are reduced, the service life of the coating is prolonged, the high temperature resistance of the coating is improved, the cracking or peeling risk is reduced, the adhesion performance is improved, the combination with the surface is enhanced, the separation risk is reduced, the coating strength is improved, the impact damage or the stress cracking is reduced, and the characteristics of improving the coating strength are achieved.
Butanol can be added into the wear-resistant coating to serve as a corrosion inhibitor in the invention, so that the corrosion speed is slowed down, the service life of the coating is prolonged, and the performance of the coating is improved, but the high concentration is required to be carefully prepared, so that skin irritation and damage can be caused.
Further, the mixed hydrocarbon is 5-10%, the mixed hydrocarbon is C9-10 aromatic hydrocarbon, and the compound number of the C9-10 aromatic hydrocarbon is Cas 64142-95-6.
C9-10 aromatic hydrocarbons are a class of organic solvents with high boiling points and good solubility properties, and in new coatings, these solvents are used to enhance the high temperature resistance of the coating and reduce the risk of cracking or flaking.
The C9-10 aromatic hydrocarbons may provide several key benefits including 1. Improving the durability of the coating, C9-10 aromatic hydrocarbons may improve the high temperature resistance of the coating, the coating may reduce the risk of cracking or flaking under high temperature and stress conditions, 2. Improving the adhesion of the coating, solvents may improve the adhesion of the coating to the surface, enhance bonding forces, reduce the risk of flaking or separation, 3. Improving the strength of the coating, C9-10 aromatic hydrocarbons may improve the strength of the coating by reducing the risk of impact damage or stress cracking, 4. Improving the corrosion resistance of the coating, C9-10 aromatic hydrocarbons may also improve the corrosion resistance, moisture resistance, and chemical resistance of the coating, increasing its durability in harsh environments or compounds.
The mass percentages of all the raw materials include the minimum percentage mass, the maximum percentage mass and any percentage between the minimum percentage mass and the maximum percentage mass, such as 20% -25% of polytetrafluoroethylene, namely including 20%, 25%, 21%, 22%, 23%, 24% and any percentage between 20% and 25%.
