Preparation method of coaster capable of heat discoloration

Abstract

The invention provides a preparation method of a coaster capable of heat discoloration. The method comprises the six steps of mixing and stirring, grinding, printing, pasting, airing and cutting. By setting the achromic point of toner a as 45 DEG C, setting the achromic point of toner b as 40 DEG C and setting the achromic point of toner c as 35 DEG C, precise coloration is conducted on the watertemperature in a feeder placed on the coaster in the 36-43 DEG C range, so that parents can precisely feed an infant, and then the situations are avoided that the infant is scalded, and low temperature of milk causes gastrointestinal discomfort for the infant after drinking.

Description

technical field [0001] The invention relates to the production technology of a coaster, in particular to a temperature-sensitive coaster capable of realizing different color changes according to temperature changes, and belongs to the technical field of kitchen utensils. Background technique [0002] We know that when parents feed their babies, the temperature of the brewed milk needs to be precisely controlled at 36°C to 43°C. If the temperature is higher than 43°C, it will easily cause scalding to the baby, and if the temperature is lower than 36°C, it will cause gastrointestinal discomfort to the baby. The traditional milk temperature control has the following disadvantages: 1) relying on personal experience to test the temperature, it is impossible to accurately control the feeding at an appropriate temperature; 2) using a temperature measuring instrument to penetrate into the milk powder may easily cause the milk to be contaminated by bacteria; 3) using a belt There are...

Problems solved by technology

The traditional milk temperature control has the following disadvantages: 1) relying on personal experience to test the temperature, it is impossible to accurately control the feeding at an appropriate temperature; 2) using a temperature measuring instrument to penetrate into the milk powder may easily cause the milk to be contaminated by bacteria; 3) using a belt There are baby bottles with electronic temperature measuring instruments, but they are expensive, not easy to rinse, and easy to damage; 4) Due to the complicated technology and high production cost, the general temperature measuring coaster only indicates that the temperature is too high and the temperature is suitable for drinking, and there is no specific temperature. Precisely set the temperature range of 36-43 ℃ for the baby's drinking habits

[0003] After searching, it is found that Chinese patent 201210502139.7 has disclosed a patent application for a temperature-sensitive coaster, and this prior art has the following defects: 1) It only introduces a coaster printed with temperature-sensitive ink, without fully disclosing the technical solution, Those skilled in the art can read the published patent, and the temperature-sensitive coaster can not accurately predict the water temperature range in the cup; 2) The temperature-sensitive ink is directly printed on the cork, and all or most of the ink will penetrate into the cork , there is a defect that the color of the coaster cannot be displayed or the color is not clear
