[0028] Also provided is the preparation method of the drying brightener, comprising the following steps:
[0029] 1) Add deionized water into the batching pot, and add isothiazolinone at the same time.
[0030] 2) Add citric acid and stir until dissolved.
[0031] 3) Add component A, stir until dissolved, and the solution becomes milky white at this time.
[0032] 4) Add component B, stir until dissolved, and the solution turns from milky white to translucent.
[0033] 5) Add sodium polyacrylate and stir until dissolved.
[0034] 6) Add isopropanol, stir until dissolved, and the final solution is a stable translucent color.
[0035] In the present invention, isomeric decanol polyoxyethylene ether (component A) and polyethylene oxide phosphoryl dipotassium salt (component B) should be added in sequence, and component B should be added after component A is fully dissolved and dispersed , the two cannot be added at the same time, if added at the same time, the transparency of...
Embodiment 1
[0037] The drying brightener of this embodiment includes the following components in mass percentage, 2% of isomeric decanol polyoxyethylene ether, 2% of polyethylene oxide phosphoryl dipotassium salt, 1.5% of sodium polyacrylate, and 1% of isopropanol. %, 1% citric acid, 0.1% isothiazolinone, and the balance of water.

Abstract
The invention discloses a melamine drying brightening agent. The melamine drying brightening agent comprises, by mass, 2-8% of isomeric alcohol ethoxylate, 2-8% of polyethylene oxide phosphoryl potassium salt, 1-5% of sodium polyacrylate, 1-5% of isopropanol, 0-4% of citric acid, 0.1-0.5% of isothiazolinone and balance water. The invention further discloses a preparation method of the melamine drier brightening agent. Isomeric alcohol ethoxylate and polyethylene oxide phosphoryl potassium salt are used, different from traditional surfactants, the structures of isomeric alcohol ethoxylate and polyethylene oxide phosphoryl potassium salt are improved, the moistening function is given full play of under the compound function of the two surfactants, hard water is softened, the moistening function of the surfactants is enhanced, and spots on melamine tableware are further removed so that the wettability of melamine can be high, the surface tension is effectively reduced, and water drying isquick. A polyacrylic acid dispersing agent is also added to effectively restrain water marks; the anti-foaming surfactants are added, so that the whole formula is low in foam. Through optimized proportioning, the whole product is stable, high in water drying speed, free of residual marks, low in foam and good in effect.
Description
technical field [0001] The invention relates to the technical field of tableware drier, in particular to a melamine drier brightener and a preparation method thereof. Background technique [0002] Commercial dishwashers are widely used. Using a dishwasher to wash tableware can greatly reduce tedious manual labor. A good drying brightener is the key to the use of dishwashers. Among them, melamine tableware is used more and more and has become the mainstream. Compared with traditional porcelain tableware, melamine tableware has the disadvantages of fast heat dissipation and slow water drying. Drier requirements are higher. However, because of its low cost and unbreakable properties, more and more restaurants use melamine tableware, so the drier for melamine tableware has a wide application prospect. [0003] Among the existing drying brighteners, the effect on ceramic tableware is good, but in recent years, melamine tableware has the characteristics of corrosion resistance, ...
