Background
With innovations and advances in technology, household dish washers are becoming more and more popular, becoming the main household appliances in people's daily lives, and becoming a necessity in more and more household daily lives. The dishwasher also needs cleaning and maintenance in the daily use process so as to prolong the service life of the dishwasher and ensure the cleaning effect of the dishwasher. Along with the extension of the service time of the dish washer, the scale accumulated in the dish washer equipment and other dirt are more and more, so that the cleaning effect of the dish washer equipment is hindered, particularly, the scale accumulated on the spray arm is influenced, the flow speed of water flow is influenced, and the cleaning effect is directly influenced.
Currently, most household dish washers are generally divided into a pre-washing stage, a main washing stage, a rinsing stage and a drying stage in a washing process, and the washing time and the water temperature of each stage are different: normal temperature water is used in the pre-washing stage, and the washing time is generally within 15 minutes; the washing water temperature in the main washing stage is higher than 50 ℃ or above, and the washing time is generally more than 30 minutes. If the cleaning agent is added before washing, the cleaning agent can only be washed at a low temperature for a short time in the pre-washing stage, and then can be discharged along with the drainage of the pre-washing stage, so that the cleaning effect is greatly reduced. Thus, the addition of the cleaning agent during the main wash phase enables an optimal cleaning of the dishwasher tank dirt to be obtained. The patent CN209789796U realizes the automatic release of the dish washer detergent in the main washing stage by adopting the wax sealed bottle to store the detergent, when the washing water temperature is higher than 50 ℃, the wax at the bottle mouth of the wax sealed bottle can be dissolved to enable the detergent to be automatically released and participate in the washing in the main washing stage, but the wax sealed bottle cannot be reused after being used up, is a secondary throwing type consumable, can cause a great amount of plastic waste and does not meet the requirements of economy and environmental protection.
Therefore, there is a great need to develop a dishwasher detergent that can be directionally released in a main washing stage to improve washing effect and a method of preparing the same.

The dishwasher detergents prepared in examples 1 to 5 and comparative examples 1 to 4 were tested for scale and oil removal under the same conditions, and the specific test methods were as follows:
1. scale preparation: and respectively placing sodium carbonate, magnesium sulfate and calcium chloride in a beaker, placing 4 transparent glass sheets 15 cm-20 cm in a dish washer, starting an ultra-fast washing mode, and repeating the washing for 10 times for standby.
2. 20 g of greasy dirt (according to the dirt preparation method in the appendix of GB 9985) is placed at the bottom of the dish-washing machine, and then 20 g of detergent is squeezed into a special detergent tank of the dish-washing machine, and an ultra-fast washing mode is started for washing. The glass sheets were then scored. Residual oil and calcium scale on the glass sheet was evaluated by visual inspection: the dirt is completely cleaned and recorded as 5 minutes; the number of dirt points is less than 4, and the total area of dirt is less than or equal to 4mm < 2 >, which is marked as 4 minutes; the number of dirt points is less than 10, and the total area of dirt is less than or equal to 4mm < 2 >, which is marked as 3 minutes; the number of dirt points is more than 10, and the total area of dirt is less than or equal to 50mm < 2 >, which is recorded as 2 minutes; the total area of dirt > 50mm2 was recorded as 0 minutes.
The results are shown in Table 2.
Table 2 comparison of the scale and stain removal capacities of the dishwasher cleaners of examples 1 to 5 and comparative examples 1 to 4
As can be seen from tables 1 and 2, the dishwashing detergent according to examples 1 to 5 has a content of 70% at a temperature of less than 50 ℃ and a detergency of 4 minutes or more, and can substantially clean scale and oil scale in a dishwasher body, and the detergency of methanesulfonic acid is superior to that of sulfamic acid and citric acid. Although the detergent of comparative example 4 retains 80%, its main detergency acidic component was not added, and its soil removing ability was evaluated as 0.
In summary, the invention combines the modified urea solution and the xanthan gum to ensure that the cleaning agent has proper viscosity, is pasty at normal temperature and is not easy to dissolve in normal temperature water, and the viscosity is reduced and is fast mutually dissolved with water under the action of water temperature in the main washing stage, thereby realizing the directional release of the cleaning agent.
