Description
Technical Field
The invention relates to the technical field of glazing care agents, in particular to glazing care emulsion and a preparation method thereof.
Background
Some surfaces of articles in the household environment, such as floors, table tops, leather and the like, are often worn and lose gloss after being used for a period of time, and wooden products, leather and the like are cracked and dry. The glazing care agent can form a protective layer on the surface of an article, and has the functions of brightening, smoothing, nourishing and the like.
At present, the glazing care agent on the market mainly comprises a solid type, a solvent type and an emulsion type.
(1) The solid type polishing care agent mainly comprises solid wax, solvent and silicone oil, and when the product is used, the surface needs to be polished and polished, the operation is complex and difficult, and the common household use is inconvenient.
(2) The solvent type glazing care agent is divided into an essential oil type glazing care agent and an acrylic resin type glazing care agent. The essential oil type glazing care agent is an anhydrous formula, and the main components are vegetable oil or vegetable essential oil and a solvent. Unsaturated bonds such as ester groups and the like exist in vegetable oil generally, and unless the vegetable oil can be absorbed by the surface quickly, the vegetable oil is smeared on the surface and contacts air and water for a long time, and reactions such as hydrolysis, polymerization and the like can occur, so that stickiness is caused, and the use experience is directly influenced. In addition, the products need to use a large amount of plant extracts, are high in price and are not environment-friendly. ② the main component of the acrylic resin type glazing care agent is acrylic resin, and leveling agent and plasticizer are also required to be contained. When in use, the product is poured on a floor and dragged by a flat mop to leave any liquid, and the liquid can be solidified into a tough and transparent polymer film after the moisture is volatilized. Before use, the dirt is usually removed by a cleaning agent, and then waxing is carried out, and the polishing can be finished after repeated polishing. Before re-waxing, the original wax substances are removed by using solvents such as kerosene and the like or amine-containing de-waxing water before re-waxing, so that re-waxing can be realized, the operation is complex and difficult, the solvents are harmful, flammable and explosive, and the common household is inconvenient to use.
(3) Emulsion type glazing care agents are classified into aerosol can type and normal pressure type according to the packaging form. The aerosol tank type emulsion polishing nursing agent mainly adopts polishing components, emulsifier, propellant, water and corrosion inhibitor, the product has unstable storage performance and is easy to separate, and the propellant is generally flammable and explosive solvent or liquefied petroleum gas, so that the aerosol tank type emulsion polishing nursing agent is neither safe nor economical. Secondly, the normal pressure emulsion type glazing care agent is mainly prepared by taking the above-mentioned components, the emulsifier and the water as main raw materials, and has the advantages of easy spreading, convenient operation and use, good glazing effect, economy and environmental protection.
However, the stability of emulsion type products is a technical problem, in order to obtain better stability, the existing polishing care emulsion generally uses wax or emulsifier with higher melting point (namely, the emulsion is solid at normal temperature), the viscosity of the emulsion is higher, heating and homogenizing are needed in production, the process is complex, the cost is higher, and meanwhile, the better polishing effect can be obtained by repeatedly polishing in the using process.
Patent document CN101220245A reports that a floor polish care agent prepared from solid wax, surfactant and water improves the convenience of use of the product, but the use of solid wax and solid emulsifier requires heating in the process of production, which increases energy consumption, increases the requirements of production equipment, increases product cost, and in addition, alkylphenol ethoxylate (4) used in the raw material has poor biodegradability. Patent document CN103990377A describes an air purifying wax, which uses a nanometer deodorant to achieve the air evolution effect, but the process needs heating and has no sterilization effect. CN106189874A describes a floor care and glazing composition and a preparation method thereof, which adopts span 60 or 85 and tween 60 or 85 to emulsify liquid paraffin to obtain a glazing effect and a product with low cost, but does not solve the problems of heating and no sterilization effect in the process. CN101067070A describes a low-cost floor care and polishing composition, which uses liquid paraffin as a polishing component, tween as an emulsifier, and adds a mildew inhibitor and water, the preparation process still needs heating, and the stability of the emulsion is poor.

Detailed Description
In order to more fully understand the technical contents of the present invention, the technical solutions of the present invention will be further described and illustrated with reference to specific embodiments.
The glossing care emulsions of examples 1-5 and comparative examples 1-8 were prepared using the ingredients shown in tables 1 and 2 in the following weight ratios:
adding the liquid glazing agent into a batching pot according to the mass percent of the components, adding the emulsifier during the shearing and stirring process, and uniformly stirring; opening homogenizing under the condition of shearing and stirring, slowly adding 1/4 of the total amount of the deionized water, and homogenizing for 10-20 minutes after water is added; closing the homogenizer, adding the chelating agent and the balance of deionized water, and shearing and stirring uniformly; adding bactericide, preservative and essence in sequence, and shearing and stirring for 5 minutes to obtain the glazing care emulsion, wherein the emulsion temperature is 15-40 ℃ in the whole preparation process.
Table 1: the glossing care emulsions of examples 1-5 were formulated with ingredients
Table 2: composition ratio of glazing care emulsion of comparative examples 1-8
Note: the HLB value refers to the hydrophilic and lipophilic values of the surfactant, and is often used as a guide parameter for the proportioning setting of the emulsifier in the emulsion. The surfactant has both hydrophilicity and lipophilicity, wherein the larger the HLB value, the stronger the hydrophilicity of the surfactant is represented, and the smaller the HLB value, the stronger the lipophilicity of the surfactant is represented.
Calculation formula of HLB value in formula:
HLB＝HLBA*A％+HLBB*B％+HLBc*C％
in the formula: HLBARefers to the theoretical HLB value, HLB, of emulsifier ABRefers to the theoretical HLB value, HLB, of emulsifier BcRefers to the theoretical HLB value of emulsifier C.
The A% value emulsifier A accounts for the mass percent of the total emulsifier, the B% value emulsifier B accounts for the mass percent of the total emulsifier, and the C% value emulsifier C accounts for the mass percent of the total emulsifier.
For example: the HLB value of polyglycerol-2 isostearate in example 1 was 7, and the HLB value of isomeric pentadecyl ether (4) was 10.5. The triethanolamine oleate has an HLB value of 12. Thus, the formula HLB value is 7 × 1.4%/(1.4% + 2% + 0.1%) +10.5 × 2%/(1.4% + 2% + 0.1%) +12 × 0.1%/(1.4% + 2% + 0.1%) -9.14.
The theoretical HLB of the emulsified mineral oil is 8-12, so the emulsifier ratio can be set in this range. The HLB value is only a reference value, which is used as a reference for experimental design.
