Description

Antistatic non-dusting material and preparation method thereof

Technical Field

The invention belongs to the technical field of materials, and particularly relates to an antistatic non-dusting 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 the outer machine impeller of air conditioner as an example, the impeller of long-term deposition can make the air conditioning efficiency decay more than 30%, and air conditioner inner machine wind channel part is in the use, and the dust is attached to and then the deposit easily on its surface, influences amount of wind, efficiency, and forms secondary pollution easily, can breed a lot of bacteria and endanger health, consequently, improves the material surface property for the difficult ash that is stained with in surface becomes very meaningful.

During the high-speed operation of the fan and the impeller, the blade (impeller blade) interacts with air to generate dynamic and static friction, so that dust adsorbs 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.

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 regularly removed and cleaned, the operation is inconvenient and time-consuming, particularly, the cleaning is troublesome, and the dust can be raised during cleaning and is harmful to human bodies. Therefore, the important significance is that the surface characteristics of the plastic are modified by the antistatic agent, and the adhesion of dust and the plastic interface is reduced.

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 QUI CK 499D.

When the measuring instrument is used, the measuring instrument is placed on the surface of a measured object, and the test key is pressed, so that the surface resistivity of the measured object is displayed, and the surface resistivity is automatically measured by adopting an ASTM standard D-257 parallel electrode sensing method and using a high-precision OP-AMP integrated amplifier.

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 resistivity, the better. A smaller value of the surface resistivity indicates a stronger antistatic ability and less susceptibility to dusting.

The results are shown in Table 1.

2. The detection method of the surface energy comprises the following steps:

surface energy is a measure of the breakdown of chemical bonds between molecules when creating a surface of a substance. First, after detecting the contact angle of the surface of the object to be measured using the contact angle detecting instrument, the surface energy may be calculated using the YGG equation, the harmonic equation, or the geometric equation. The smaller the surface energy value is, the better the surface energy value is, the less the interface is adhered with organic matters and water, and the better the dustproof effect is. A smaller surface energy value indicates less dusting. The results are shown in Table 1.

3. The detection method for preventing dust staining comprises the following steps:

the fans prepared according to the proportion and the embodiment examples are respectively placed into a communicated air duct system, standard dust simulating real dust of the atmosphere is periodically added into the air duct system, and 20g of the standard dust is added into the air duct system every 2 hours. The fan is operated for a period of time and then stopped for a period of time, which is considered to be one cycle. And in each period, blowing the soot for 10 minutes, standing for 10 minutes, wherein the soot blowing speed is 1-2 m/s. The cycle lasts 2 days. And after the experiment is finished, counting the sum of the dust adhering amount of each sample to be tested. Repeated for multiple times and statistically analyzed. And calculating the dust-proof effect, wherein the dust-proof effect refers to the dust-proof quantity reduction ratio of the modified fan blade relative to the original fan blade (namely the comparative example) under the condition of changing the material formula. The larger the anti-dusting effect value, the better. The results are shown in Table 1.

In Table 1, "Ω/□" refers to the sheet resistance.

It can be seen from the data in tables 1 to 3 that the surface resistivity and surface energy can be reduced and the effect of non-dusting is improved by adding antistatic agent, wollastonite, zirconium aluminate, sodium dodecyl sulfate, ethylene glycol ester, stearate and acetone.

The inventors further adjusted the addition ratio of the fluorine-modified thermoplastic resin base particles in addition to example 1, and the addition ratio of the fluorine-modified thermoplastic resin base particles was 5%, 6.49%, 10%, 18%, 19%, 45%, 46%, 60%, and 76.9%, respectively, with reference to the mass percentage of the first thermoplastic resin base particles. Research results show that under the condition that the mixture ratios of other components are the same, the fluorine modified thermoplastic plastic master batch has a better non-dusting effect when the addition amount is 5-80.8%.

Fig. 4 and 5 are comparative results of the dust staining of the comparative examples and examples. Both fig. 4 and fig. 5 show the results of tests performed in the same system for testing non-dusting. The dust amount and the dust concentration in the system are large, dust is added into the system periodically, a dust adhering picture on the surface of the material in a period of time is tested (the test is the effect of combining the static dust deposition dynamically), and the specific operation steps are the same as those of the dust adhering prevention detection method. As can be seen from fig. 4, the comparative example is more dusty, while example 8 is less dusty, even not dusty in a shorter time. As can be seen from fig. 5, the comparative example is more dusty, whereas example 1 is less dusty, even not dusty in a shorter time.
