Problems solved by technology

The radiation measurements of the materials prepared by this invention are all lower than the environmental protection requirements. The environmental protection requirements radiation value is less than 0.1ucV, the measured value reaches 0.03ucV, and the negative ion emission reaches more than 9000 / cubic centimeter, which meets some requirements, but there is still this negative ion release. The duration is short, and the problems of low tensile strength and low elongation of the coating itself are worthy of further solution and optimization

Abstract

The invention belongs to the technical field of water-based coatings, and discloses a polymer water-based coating and a preparation method thereof. The composition of the coating includes: a fullerene activator, a hexacyclic stone, a water-based polyurethane resin, and a polyvinyl alcohol material. The preparation method includes the following steps: taking the hexacyclic stone and pulverizing it to obtain micropowder, and mixing the fullerene activator with the hexacyclic stone micropowder. , carry out plasma treatment to obtain plasma treatment material, take plasma treatment material and add water, ultrasonically disperse, react in hydration kettle, filter, take filter residue and grind, add polyvinyl alcohol material and mix evenly, vacuum concentration to obtain concentrated material, take concentrated material Add water-based polyurethane resin and additives and mix evenly. The water-based paint disclosed in the invention has good tensile strength and elongation, and can increase the duration of releasing negative ions.

Description

technical field [0001] The invention relates to the technical field of waterborne coatings, in particular to a polymer waterborne coating and a preparation method thereof. Background technique [0002] Negative ions: Simply put, it refers to negatively charged oxygen ions, which are colorless and odorless. The molecular formula of negative air ions is O 2 -(H 2 O) n , or OH-(H 2 O) n , or CO 4 -(H 2 O) n . Negative ions can not only promote the human body to synthesize and store vitamins, but also strengthen and activate the human body's physiological activities. Therefore, it is also called "air vitamin". It is believed that, like food vitamins, it has a very important impact on the life activities of the human body and other organisms. , For example, after a thunderstorm, the negative ions in the air increase, and people feel comfortable. In an air-conditioned room, because the negative ions in the air almost disappear after a series of air-conditioning purificat...
