Description

Repairing agent and preparation method and use method thereof
Technical Field
The invention relates to a non-stick cooker repairing agent, in particular to a repairing agent capable of increasing or repairing the non-stick performance of cookers, and a preparation method and a use method thereof.
Background
Non-stick cookware has been widely used in modern life and is characterized by a non-stick characteristic because the cookware surface has a special coating. The coating compound has the advantages of high temperature resistance, low temperature resistance, self-lubricating property, chemical stability and the like, so that the non-stick cooker is different from common cooking tools. However, the longer the non-stick cookware is used, the more the non-stick performance decreases, and even the non-stick performance is lost. The prior art generally provides improvements in the preparation of utensils to achieve the non-stick characteristics of non-stick cookware, and does not provide a corresponding repair when there is a problem with the non-stick characteristics of the utensils. The invention provides a repairing agent, which is used for forming a non-stick coating on the surface of a cooker so that the cooker has non-stick performance again, thereby reducing the preparation cost and the use cost of a user. In addition, the repairing agent of the invention can make the cooker regain the non-stick property in a short time, and is more convenient to use.
The prior art CN101955697A discloses a ceramic non-stick coating with an antibacterial effect, and particularly discloses that the coating is prepared from A, B, C three components in a weight ratio of 2: 0.5-2: 0.1-2, wherein: the component A comprises: mixing the following components in percentage by mass: dispersing 50-100% of silica sol, 0-50% of temperature-resistant pigment, 0-20% of extender pigment, 0-2% of dispersing aid and 0-2% of leveling aid, and then grinding for more than 2 hours to obtain a component A; and B component: mixing 0.4-1.5% of acetic acid and the balance of at least one silane by mass; and C, component C: dispersing and dissolving 1-10% of alcohol-soluble acrylic resin, 0-30% of non-stick auxiliary agent and 1-50% of antibacterial material in 50-95% of isopropanol by mass to obtain a component C, wherein the addition amount of the antibacterial material is 1-25% of the total mass of solid components in A, B, C three components. The coating has various components, complex manufacturing process and higher production cost.
In addition, prior art CN102634278A discloses a high temperature resistant ceramic coating for non-stick cookware and a preparation method thereof, wherein the coating is prepared by mixing component a and component B at a weight ratio of 2.0-2.2:1.0-1.2, the component a is prepared from silica sol, alumina sol, zirconia sol, mica powder, iron oxide black, high temperature alumina, isopropanol, deionized water, cellulose carboxymethyl acetate butyrate, and fluorosilicone oil, and the component B is prepared from methyltriethoxysilane, ニ methyldimethoxysilane, phenyltriethoxysilane, isopropanol, and ethanol; the preparation method comprises the steps of mixing the component A and the component B of the coating according to the weight ratio of 2.0-2.2:1.0-1.2, and carrying out sealed stirring and curing for at least 3 hours at 35 ℃ and under the condition of 200rpm at 150 ℃ to obtain the coating, wherein the coating mainly utilizes the high-temperature resistance stability of-Si-O-bonds, so that the excellent high-temperature performance of the coating is ensured. However, because of the use of inorganic components such as iron oxide black and high temperature alumina, the coating uniformity is difficult to control, and the coating is easy to fall off.
The prior art CN97100857 discloses a non-stick coating with low fluorine release, the dry solid composition of which comprises fluorocarbon polymer less than 40% of the total weight, inorganic powder filler more than 10% of the total weight and part of binder. The coating can maintain low-density fluorine release level and reduce food contamination. However, the coating uses a fluorocarbon polymer such as polytetrafluoroethylene, which is a non-stick cookware that generally cannot be cooked at higher temperatures because the ptfe tends to be unstable above 260 c and begins to decompose and produce substances harmful to humans when the temperature is raised to about 310 c and above. In recent years, people pay more attention to the health effect of fluorine-containing substances released by non-stick cookware coatings, so that more healthy and environment-friendly non-stick cookware coatings are urgently needed.

Detailed Description
The invention is further illustrated below with reference to specific examples. It is to be understood, however, that these examples are illustrative only and are not to be construed as limiting the scope of the present invention. The experimental procedures, in which specific conditions are not noted in the following examples, are generally carried out under conventional conditions or conditions recommended by the manufacturers. All percentages and parts are by weight unless otherwise indicated.

In the technical scheme of the invention, the air conditioner is provided with a fan,
the silicone oil used in the present invention is a silicone oil having a non-stick effect, which is used to provide a repair agent with higher non-stick properties, good smooth touch, water repellency, and durability of a repair coating. The silicone oil used in the present invention is selected from commercially available polydimethyl silicone oil, phenyl silicone oil, methylphenyl silicone oil and fluorine modified silicone oil. Silicone oils increase in molecular weight and viscosity with the number of chain segments n, so silicone oils can have a variety of viscosities, from 0.65 centistokes up to millions of centistokes. The invention can adjust the preparation process of the silicone oil according to the viscosity requirement of the silicone oil. If silicone oil with low viscosity is to be prepared, acid clay is used as a catalyst and telomerization is carried out at the temperature of 180 ℃, or sulfuric acid is used as a catalyst and telomerization is carried out at the low temperature; an alkaline catalyst can be used if a high viscosity silicone oil is produced. According to the invention, silicone oil with the viscosity of 50-5000 centistokes is preferably used, the weight percentage of the silicone oil in the repairing agent is 10-50%, if the weight percentage is less than 10%, the durability of the repairing coating is poor, and exceeds 50%, and the difficulty of emulsification with water is increased.
The non-stick silicone oil used in the invention can react with the surface of the cooker to form a long-term non-stick coating, and the non-stick coating still exists even after being cleaned by using a cleaning agent.
The specific working principle is shown in fig. 1:
under the condition of heating, hydroxyl of silicon oil in the repairing agent can be condensed with hydroxyl on the surface of the ceramic coating, so that the repairing agent is tightly combined with the surface of the cooker, and the non-stick property of the surface of the coating can be repaired.
The surfactant is a substance which is added in a small amount and can cause the interface state of a solution system to change obviously. The molecular structure of the surfactant has amphipathy: one end is a hydrophilic group and the other end is a hydrophobic group. The surfactant is divided into ionic surfactant, non-ionic surfactant, zwitterionic surfactant, compound surfactant and the like. The surfactant used in the present invention may be soybean lecithin, which is a zwitterionic surfactant, and polyglycerin fatty acid ester, polysorbate, glyceryl monostearate or glyceryl monooleate, which is a nonionic surfactant. The surfactant in the repairing agent can be mixed with the silicone oil and the deionized water by stirring to generate an emulsification effect, so that the silicone oil and the deionized water can be prevented from being separated, and the silicone oil is prevented from floating on the surface of the repairing agent.
The thickener is used for increasing the viscosity of the repairing agent and preventing the silicon oil from being separated from water. The thickening agent of the present invention is water soluble and may be selected from the group consisting of methylcellulose, ethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylmethylcellulose, sodium alginate, gelatin, agar, carrageenan, gum arabic, or peach gum. The content of the thickening agent has a remarkable influence on the stability of the repairing agent, and the thickening agent accounts for 0.2-10% of the weight percentage of the repairing agent, and preferably 1-5%.
The preservative can prevent the repairing agent from being rotten and increase the storage time of the repairing agent. The preservative can be selected from calcium propionate, sodium propionate, potassium sorbate or sodium benzoate, and the content of the preservative in the repairing agent is 0.1-2% by weight.
