Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a hardening coating and a preparation method and application thereof.
Background
With the continuous improvement of the living standard of people, most kitchens are provided with smoke exhaust hoods, the kitchen can enable the air with the smoke to be exhausted out of the kitchen through the smoke exhaust pipelines, the odor of people choking in the kitchen can be reduced, and the smoke exhaust ventilator can exhaust the smoke to reduce the smoke inhaled by the human body, so that the kitchen is beneficial to the health of the human body.
In the using process of the smoke exhaust ventilator, the generated smoke is taken away through the negative pressure generated by the high-speed rotation of the impeller. Resulting in a large amount of grease being stored in the filter screen and the inner cavity of the range hood and eventually flowing into the oil collector-cup. When the old oil in the oil cup is accumulated to a certain amount, the old oil is detached for cleaning. Old oil at the bottom of the oil cup can be coagulated into a relatively intractable precipitate, and the old oil can be cleaned by a cleaning agent with strong alkalinity, which is time-consuming and labor-consuming. Alkaline cleaners can also cause some damage to the skin of a person. There is a great deal of resin oil cups in the industry at present, so that development of an oil cup with hydrophobic and oleophobic properties is very necessary.
CN111849315a discloses a salt mist resistant powder coating and a preparation method thereof, wherein the raw materials comprise the following components in parts by weight: 40-55 parts of polyester resin, 15-25 parts of epoxy resin, 6-15 parts of methyl phenol type phenolic resin, 3-7 parts of curing agent, 1-1.8 parts of flatting agent, 5-10 parts of brightening agent, 0.5-1.2 parts of defoaming agent and 0.4-0.8 part of benzoin. The powder coating is applied to the equipment of the equipment, especially the equipment in the severe environment, such as: the coating of the kitchen ventilator and the ware has very excellent salt fog resistance, the protective coating generates strong corrosion and damage, the ware is prevented from being corroded, but the water and oil repellency is poor, and the use effect in an oil cup is poor.
CN109762449a discloses a high-gloss self-cleaning powder coating and a preparation method thereof. The coating comprises the following components in parts by mass: 30-50 parts of hydroxyl-terminated polyester resin, 3-15 parts of fluorocarbon resin, 15-75 parts of curing agent, 1-10 parts of modified nano silicon dioxide, 0-2 parts of pigment, 10-40 parts of filler and 0-15 parts of auxiliary agent, and the powder coating has excellent hydrophobic property, good weather resistance, high gloss, strong adhesive force and strong impact resistance, can be used for coating surfaces of outdoor equipment, guardrails, billboards and the like and surfaces of indoor equipment, smoke exhaust ventilator and the like, but has poor hardness, so that the application of the coating is limited.
CN108192498A discloses an underwater super-oleophobic self-cleaning UV-curing metal coating, a coating and a preparation method thereof, and application in the fields of smoke exhaust ventilator, non-stick pan, ship antifouling and the like. The coating has super-hydrophilic and super-oleophilic properties in air, has a contact angle of 0 DEG for water and oil in the air and a contact angle of more than 150 DEG for oil drops in the water, and can be applied to the fields of ship antifouling, smoke exhaust ventilator, non-stick pan and the like, but has poor hardness, so that the application of the coating is limited.
The paint in the prior art has the problems of poor hydrophobic performance, poor oleophobic performance, low hardness and the like, and the performances of the paint are not balanced. Therefore, developing a coating with good hydrophobic performance, good oleophobic performance, high hardness and scratch resistance to meet the application requirements of the coating is a problem to be solved in the field.
