Abstract

The invention belongs to the technical field of pH sliding conditioning agents in basic dyestuff dying, and in particular relates to a temperature-controlled nanoscale microcapsule water pH sliding conditioning agent which is characterized by comprising the following components by weight parts: 8-16 parts of a microcapsule prepolymer, 5-15 parts of aminophosphonic acid, 25-40 parts of an amide compound, 1.5-2.5 parts of caustic alkali, and 26.5-60.5 parts of distilled water, wherein the microcapsule prepolymer is prepared from C3-5 unsaturated fattyacid, an initiator, isopropyl alcohol and the distilled water by reaction. By adopting the method, the production technology process is shortened, the energy consumption and the waste water discharging are reduced, the safety is high, the cost is low, and the stability is high. The application range of dye types and technology conditions can be widened during dyeing.

Description

technical field [0001] The invention belongs to the technical field of pH sliding regulators in basic dyeing, and in particular relates to a temperature-controlled, nanoscale microcapsule water-based pH sliding regulator. Background technique [0002] In many occasions in industry and life, it is necessary to adjust and effectively control the pH of the water, such as the circulating water of the cooling water system required by the industry, boiler feed water, etc. In order to ensure the safety of the boiler, it is necessary to temper the water and add an appropriate amount of acid and alkali Liquid, so that the pH value of the water in the specified value or set range. The fish farming industry must also adjust the pH of the water to achieve the purpose of fish farming. [0003] There are two types of pH regulators: pH buffer type and pH sliding type. The pH buffer regulator is mainly composed of strong base and weak acid salt, strong acid and weak base salt, weak base a...
