AI Technical Summary

Problems solved by technology

Among them, metal powder has a high density, and a large volume fraction is required to form a conductive path. The surface layer is easily oxidized, which will reduce or even lose conductivity, and has poor corrosion resistance, which affects other properties of the coating. Therefore, the application of metal powder as a conductive filler is subject to certain restrictions. Restrictions; antistatic agents have poor temperature resistance, water resistance, oil resistance, corrosion resistance, durability, and unstable antistatic performance; early antistatic coatings generally use carbon-based materials as conductive fillers. With the development of science and technology, gradually appeared New conductive fillers such as semiconductor metal oxides and nano-conductive powders are used in electrostatic coatings. These materials are light in color and easy to color, which enriches the color system of antistatic coatings. However, when these materials are used alone, they are added in large amounts , the dispersion stability is poor, which will affect the performance of the coating and its coating

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antistatic latex paint. Background technique [0002] Static electricity is an objective natural phenomenon, which can be produced in many ways, such as contact and friction. The action of the human body or the contact, separation, friction or induction with other objects can generate thousands of volts or even tens of thousands of volts of static electricity. With the continuous improvement of people's living standards, the utilization rate of household appliances is increasing day by day. Because household appliances are limited by various factors such as placement location and volume, it is impossible to install anti-static devices with good anti-static effects on household appliances, but because People are often in contact with household appliances, so that household appliances are often charged with static electricity. Static electricity can inadvertently break down el...
