Description

Technical Field

[0001] The invention relates to a solubilizer capable of improving the alkali resistance of an industrial cleaning active agent and a preparation method thereof, belonging to the technical field of research on the alkali resistance of cleaning active agents. Background Art

[0002] Industrial and consumer cleaning detergents typically increase their alkalinity to boost the saponification rate of oils and fats during the cleaning process, thereby improving their oil removal efficiency and cleanliness. However, most surfactants used in industrial cleaning contain large amounts of ethylene oxide and propylene oxide polymers, and most of these surfactant structures cannot dissolve and disperse well in alkaline systems. This often results in poor alkaline resistance and prone to precipitation and delamination at higher alkalinity levels, making effective cleaning solutions impossible to implement.

[0003] To address the poor alkaline resistance of industrial and consumer cleaning detergents, a two-component to multi-component solution has been adopted. This involves using an alkaline inorganic component as either Agent A or Agent B, while an alkaline-resistant active emulsifier, primarily as Agent B or Agent A, is added proportionally during the production process. While this solution is gradually gaining popularity in the cleaning market, many customers require a single-component solution, leading the cleaning industry to seek superior solubilizers to address this issue.

[0004] Currently, the mainstream method at home and abroad is to improve the solubility of non-alkali-resistant surfactants in high-alkali solutions by synthesizing special structural materials in compound cleaning agents. However, the synthesis of such solubilizing agents has the disadvantages of complex process, high energy consumption, and high cost. CN109504549 A discloses the preparation and application of an environmentally friendly alkali-resistant low-foaming solubilizing agent, and CN 112724050 A discloses a phosphorus-free alkali-resistant solubilizing agent and its preparation and application. However, both of these solubilizing agents are synthesized under high temperature and high pressure conditions to achieve certain solubilizing properties. The synthesis process is complicated and requires continuous nitrogen replenishment. Summary of the Invention

[0005] To address the technical problem of existing alkali-resistant solubilizers for industrial and consumer cleaning detergents requiring synthesis under high-temperature, high-pressure conditions, the present invention provides a solubilizer and preparation method for improving the alkali resistance of industrial cleaning agents. This invention utilizes low-temperature modification and a simple compounding reaction to produce a highly effective solubilizer, effectively increasing the solubility of cleaning agents in alkaline environments.
