Description

Antistatic easy-cleaning material and preparation method thereof

Technical Field

The invention belongs to the technical field of materials, and particularly relates to an antistatic easy-to-clean material and a preparation method thereof.

Background

Some plastic products often suffer from dust deposition during use, such as: dust in the air can be suspended in suspension, bacteria can float, the dust can be deposited on the surface, and the air can be dynamically rubbed, so that the dust is electrostatically adsorbed. Not only is the frequent cleaning operation troublesome, but also the service life of the equipment is influenced. The following description will be made by taking a fan blade or an impeller as an example.

Taking an air conditioner outer machine impeller as an example, the impeller with long-term dust accumulation can attenuate the air conditioning cooling efficiency by more than 30%, and when an air conditioner inner machine air duct component is in use, dust is easily attached to the surface of the air conditioner inner machine air duct component and then deposited, so that the air volume and the energy efficiency are influenced, secondary pollution is easily formed, and a lot of bacteria can be bred to harm health.

During the high-speed operation of the fan and the impeller, the blades (impeller blades) and air are in dynamic and static friction with each other, so that dust can adsorb charged ions. About 90% -95% of suspended dust is positively or negatively charged, the like charges repel each other to enhance the stability of the dust in the air, opposite charges attract each other to promote the dust to gather and settle, the rotating fan blades rub against the air to carry charges, and the charged body has the property of attracting light and small objects, so that the dust can be attracted to the fan blades. The literature reports that solid suspended matters with the particle size of less than 75 microns in air, particularly dust with the particle size of more than 0.1-10 microns, have higher dispersity, the finer the particles of the dust are, the longer the floating time in the air is, and the dust also has bacterial corpses, oil stains, water and some flocculent fibers in the air, so that the appearance of the dust suspended in the air is very complicated, and the multi-component dust is more easily enriched and adhered to an impeller or fan blades, and the fan blades or the impeller gradually become very dirty for a long time, and the normal working efficiency of the fan blades and the impeller of a heat dissipation fan in the internal impeller of an electric appliance such as an air conditioner, a dust collector and the like is influenced if the fan blades and the impeller are stained with dust for a long time, so that the fan blades and the impeller which are easy to clean are prevented from dust become.

When the existing unmodified fan blades or impellers run for a long time or stand for a period of time, a lot of dust can be deposited on the impeller or the fan blades, and the fan blade impeller becomes very dirty gradually, so that the appearance of the fan blade impeller is seriously influenced. Moreover, like the internal impeller of the air conditioner, the dust collector and other electric appliances, the impeller of the cooling fan is stained with dust for a long time, so that the normal working efficiency of the impeller can be influenced, for example, the internal impeller of the air conditioner is stained with dust, the wind resistance can be increased seriously, the refrigerating effect of the whole machine is influenced, and in addition, the dust is enriched in the fluorine of the fan blade, the dynamic balance of the rotation of the fan blade can be influenced, and the influence of the local air output of the fan blade and the impeller and other aspects is seriously influenced. The prior technical scheme is that the dust is cleaned by regularly detaching the dust, so that the dust cleaning is troublesome, complicated and time-consuming, especially the cleaning is troublesome, and the dust can be raised to be harmful to human bodies during cleaning. Therefore, the electrostatic adsorption is reduced by the electrostatic force of the antistatic modification, which is of great significance.

1. The detection method of the surface resistivity comprises the following steps:

the surface resistivity is the ratio of the potential gradient parallel to the direction of current flow through the surface of the material to the current per unit width of the surface, expressed in ohms.

The surface resistivity can be directly detected by a surface resistance tester, and the operation method can be referred to the specification. The surface resistivity test instrument for all data measurements was QUICK 499D.

Surface resistivity: this parameter is used for thin film materials of a certain thickness, which is defined as the ratio of the dc voltage drop per unit length over the surface to the current flowing per unit width.

The smaller the value of the surface energy, the better. A smaller surface energy value indicates less dusting. The results are shown in Table 1.
