Detailed Description
The following describes embodiments of the present invention in detail. The following examples are illustrative only and are not to be construed as limiting the invention. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products commercially available.
In one aspect of the invention, the invention provides an anti-friction fire-setting coating. According to the embodiment of the invention, based on the total mass of the anti-friction fire-retardant coating, the anti-friction fire-retardant coating comprises the following components in percentage by mass: 40% -10% of TH resin; 10% -40% of a toughening agent; 3% -5% of functional filler; 10% -20% of common filler; 0.08 to 0.1 percent of curing agent; and the balance of the first solvent. The inventor finds that the coating with the composition and the proportion is coated on the surface of metal, particularly the surface of alloy containing aluminum, magnesium and the like which are easy to ignite, the adhesion is ideal, and the formed coating can effectively prevent the metal from generating friction sparks when the metals collide with each other and has good anti-corrosion and anti-explosion functions. Moreover, the coating can be effectively coated on the surface of light-weight metal for a new energy automobile to form a coating with good friction and fire prevention, corrosion prevention and explosion prevention performances, so that the safety of the new energy automobile is effectively improved.
According to the embodiment of the invention, the preparation method of the anti-friction fire-retardant coating is not particularly limited, and the skilled person can flexibly select the anti-friction fire-retardant coating according to the actual needs. In some embodiments of the present invention, the above-described coating components may be mixed in proportion and then adjusted to have a suitable viscosity by the first solvent, suitable for forming a coating layer by painting or spraying.
According to an embodiment of the present invention, the TH resin used may contain a modified tung oil, an epoxy resin and a second solvent. The modified tung oil is obtained by opening double bonds in natural plant tung oil (the tung oil structure belongs to an alkene compound and has three double bonds) and maleic anhydride through chemical reaction, and the obtained modified tung oil has better weather resistance and adhesive force. The epoxy resin may be E44(6061) and the second solvent may be xylene. According to some embodiments of the present invention, the modified tung oil, the epoxy resin and the second solvent may be present in a mass ratio of 2:1: 2. Therefore, the materials and the proportion can be used for cooperating with other components in the coating, so that the obtained coating has good anti-friction and anti-fire functions and good anti-corrosion and anti-explosion functions.
According to embodiments of the present invention, the toughening agent employed may be chlorosulfonated polyethylene. In some embodiments of the present invention, chlorosulfonated polyethylene that may be employed includes, but is not limited to, type 40 chlorosulfonated polyethylene. In some embodiments of the present invention, the toughening agent may be dissolved in xylene and provided as a solution, including, for example, but not limited to, formulation of type 40 chlorosulfonated polyethylene into a 20% xylene solution for future use. The toughening agent can effectively improve the impact resistance of a coating formed by the coating, so that the coating has good mechanical property, and the toughening agent can effectively cooperate with other components in the coating, so that the coating formed by the coating has ideal service performance.
According to an embodiment of the present invention, the functional filler used may be at least one of a solid lubricant filler, a flame retardant filler, an elastic filler, and a phase change filler. By adopting the functional filler, the mutual comprehensive effect of the functional filler can ensure that the heat generated by kinetic energy is reduced when a coating formed by the coating is impacted, so that the temperature of the coating is not higher than 600 ℃, the combustible gas under the environment is not ignited when impacting is performed (the ignition temperature of the combustible gas is 650 ℃), and the explosion-proof purpose is effectively achieved.
According to an embodiment of the present invention, the solid lubricating filler may be at least one of silicon carbide and molybdenum disulfide. In some preferred embodiments of the invention, the solid lubricating filler has a particle size of less than 330 mesh. By adopting the solid lubricating filler, when metals mutually impact, sliding friction is changed into rolling friction, so that the generation of friction kinetic energy is reduced as much as possible, and further, the temperature of the metals is not too high to ignite combustible gas in the environment. In some embodiments of the invention, the solid lubricating filler is added in an amount of 0.1-0.2% by mass based on the total mass of the coating.
According to an embodiment of the present invention, the flame retardant filler may be a composite phosphorus-based flame retardant or a water-soluble crystalline flame retardant.
