Description

Technical Field

[0001] The invention relates to the technical field of wall surface anti-yellowing and anti-yellowing agents, in particular to a wall surface anti-yellowing and anti-yellowing agent and a production method thereof. Background Art

[0002] The wall anti-yellowing agent is a highly efficient and environmentally friendly wall repair material, specifically developed to address issues such as wall yellowing, mildew, and oxidative discoloration. This product utilizes core ingredients such as alkaline neutralizers, redox agents, and organosiloxanes to effectively decompose residual yellowing substances in the wall, adjust the pH value, and form a hydrophobic protective layer on the surface to prevent water vapor penetration and secondary yellowing. The addition of tea tree essential oil provides natural antibacterial and mildew-proof properties, making it suitable for a variety of substrates such as latex paint and putty layers. This anti-yellowing agent boasts strong permeability, long-lasting action, and convenient construction, making it suitable for a variety of scenarios, including homes, offices, and businesses. The water-based, environmentally friendly formula does not affect the aesthetics of the wall after drying. It is suitable for use in humid, high-alkali environments prone to yellowing, helping to restore the whiteness of walls to their new, pristine whiteness and extending the life of decorative elements.

[0003] The wall anti-yellowing and yellowing-eliminating agents in the prior art can eliminate the yellowing of the wall during use, effectively solving the problem of difficult-to-clean anti-yellowing. However, a suitable environment is required during use to effectively use the anti-yellowing agents. For example, in an environment with a relative humidity greater than 85%, the active ingredients of the water-based anti-yellowing agents will hydrolyze and become ineffective prematurely, and the reaction rate will drop by 50% below 5°C. Above 35°C, excessive oxidation may occur, leading to fading of the wall. Therefore, different weather changes in winter in northern my country and summer in southern China will result in different usage effects, so traditional anti-yellowing agents cannot be used efficiently. At the same time, traditional anti-yellowing agents also have a pungent odor during use, which requires operators to take multiple layers of protection during use to solve the pungent odor problem. Summary of the Invention

[0004] (1) Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a wall anti-yellowing and yellowing-eliminating agent and a production method thereof, which solves the problem that traditional yellowing-eliminating agents cannot exert their efficient use effects; at the same time, traditional yellowing-eliminating agents also have a pungent odor when used, resulting in operators needing multiple layers of protection during use to solve the problem of the pungent odor.

[0010] A method for producing a wall anti-yellowing and anti-yellowing agent comprises the following specific steps: Step 1: Premixing the water-based solution: Heat deionized water to 1% HCl, add the alkaline neutralizer and stir until completely dissolved, and adjust the pH of the system to between 7-8. Step 2: Oxidation system construction: Slowly add the redox agent and maintain a stirring rate of 300 rpm to prevent local high concentrations from triggering side reactions; Step 3: Introduction of ethylene glycol compounds: Ethylene glycol, penetrant, dispersant, organosiloxane, and tea tree essential oil are pre-emulsified and added to the system. Ultrasonic treatment at 20kHz / 5min is performed to improve dispersion uniformity. Step 4: Rheological properties control: Adjust the viscosity to 2000-3000 mPa·s by adding 0.2%-0.5% polyurethane thickener; Step 5: Post-processing: The prepared raw materials will be cooled naturally at a constant temperature, screened through a 500-mesh vibrating screen, and stored by filling and sealing.

[0011] Preferably, the deionized water in step 1 is heated to 35-40°C.

This can effectively improve the use efficiency in a relatively humid environment and prevent the use from being affected.

[0015] 3. The present invention adds ethylene glycol compounds as freezing inhibitors during the raw material preparation process, which can enable the anti-yellowing agent to maintain effective molecular activity in a 0°C environment, avoid incomplete oxidation reaction residues caused by low temperature, and effectively solve the problem of improving usage efficiency in a low-temperature environment and preventing usage from being affected.

[0016] 4. The present invention adds sodium percarbonate microcapsules. By adding sodium percarbonate microcapsules during the raw material preparation process, the start time of the oxidation reaction can be delayed to 15 minutes, thereby avoiding excessive oxidation caused by high temperature accelerated reaction, and effectively improving the use efficiency in a high temperature environment and preventing the use from being affected. This beneficial effect can be combined with beneficial effect 3 to achieve the preparation and use of raw materials in different environments. Different oxidizing agents can be selected according to different situations, which can give full play to the use effect of the oxidizing agent, reduce the defects of the traditional oxidizing agent, and reduce the limitations.
