Patent Application
20230193434
The present application relates to the technical field of quickly water-soluble solid metal materials, and in particular to a quickly water-soluble solid metal material and a preparation method thereof.
The cleaning materials, currently available on the market, are chemically-synthesized products basically, such as laundry powder, laundry detergent, and laundry beads, which are all based on petroleum-based polymer compounds. The current detergent surface active materials are made of polyethylene glycol—Polyoxyethylene. And there is another type of the detergent surface active material that is made of polyols, such as glycerol, pentaerythritol, and sorbitol. The residue of washing products, remaining on clothes after each washing, has a great impact on human health, such as irritation to the skin and damage to internal organs. Moreover, after discharging of the washing wastewater, the chemicals in the detergent cannot be effectively degraded by bacteria in nature, causing secondary pollution to the environment.
Magnesium metal is a silver-white light metal, which is stored in large quantities in alkaline earth and seawater (the content is about 0.4%), is light in weight and chemically active, and can react with water to generate hydrogen. Magnesium element is widely distributed in nature and is also one of the essential elements of the human body (the total magnesium content of a normal adult body is about 25 g, 60% to 65% of which exist in bones and teeth, and 27% are distributed in soft tissues). Magnesium is a necessary substance in the human body in terms of the metabolism of calcium, vitamin C, phosphorus, sodium, potassium, etc., and plays an important part in the normal functioning of neuromuscular functions and blood glucose conversion. Therefore, magnesium is one of the essential elements of the human body. If it is introduced into washing products, it will be bound to reduce the harm of washing products to the human body.
The technical problem solved by the present application is to provide a quickly water-soluble solid metal material and a preparation method thereof. The solid metal material provided by the present application has a fast dissolving speed in water and a good washing effect, and is harmless to the human body as well as the environment.
In view of this, a portable, environmentally-friendly solid washing material can be produced by using magnesium, which is convenient for everyone to carry during the trip. Specifically, the present application provides a quickly water-soluble solid metal material for washing, comprising:
Optionally, the washing product further comprises: 3-8 PBW of aluminum, 0.1-5 PBW of copper, 0.3-0.5 PBW of calcium, 0.1-1.0 PBW of iron, 0.1-0.2 PBW of zinc, and 0.5-0.8 PBW of sodium.

The present application also provides a method for preparing the quickly water-soluble solid metal material, comprising the following steps:
According to the proportion of ingredients, the raw materials are mixed and melted, then cast, then drawn and formed, and finally heated and punched out to form a spherical shape to obtain a quickly water-soluble solid metal material.
The present application provides a quickly water-soluble solid metal material, which comprises magnesium, gadolinium, yttrium, praseodymium, neodymium, platinum, hafnium, nickel, potassium and manganese in specific proportions. After the quickly water-soluble solid metal material provided by the present application dissolves in water, the pH can be around 10, which can dissolve the grease adhered to the clothes by the human body, kill the mold.
