What are the design principles of antistatic fluid formulations? Is an antistatic fluid an antistatic agent?

The development direction of antistatic agents is permanent antistatic agents and nanomaterial antistatic agents, such as nano silica and nano zirconium dioxide, when the particle size of silicon dioxide and zirconium dioxide reaches nanometers, this material has electrical conductivity, Nalut has increased investment in this area, and it is expected to be industrialized in three years.

The antistatic fluids in this market can be classified into washable antistatic fluids and ordinary antistatic fluids according to their functions.

Washable antistatic fluids include: Nalute antistatic fluid.

Common antistatic fluids are: Colcoat antistatic fluid, Polyfax antistatic fluid and ACL antistatic fluid.

The main difference between washable antistatic fluid and ordinary antistatic fluid is that it is resistant to washing.

Nalute washable antistatic fluid, rinsed with water, or wiped with a towel without losing its anti-static function.

Ordinary antistatic liquid cannot be washed with water, rinse with water or wipe with a damp rag, it will lose its anti-static function.

Note: The antistatic liquid mentioned here refers to the externally coated antistatic fluid, commonly known as antistatic liquid.

In addition, antistatic fluids are also known as antistatic agents, but they are called differently.

Here's what people have done about antistatic agents for fabrics:

Antistatic studies.

The antistatic properties of the original polyester fabric, antistatic agent FK-311 treatment and washed fabrics are shown in Table 1.

Table 1 Test data of antistatic agent FK-311.

Note: Relative humidity = 40%.

The data in Table 1 show that compared with the original fabric, the antistatic agent FK-311 treatment has significantly lower electrostatic voltage and half-life, and has good antistatic properties, and can still maintain good antistatic properties and good durability after 10 and 20 times of washing. Tests on acrylic, nylon, and wool-polyester fabrics yielded similar results.

Antistatic agent FK-311 is a cationic polymer, which can be targeted by hydrophobic fibers, and the hydrophilic group is on the surface of the fiber to form a hygroscopic and ionic film, which is conducive to the rapid escape of electrostatic charge and achieves the purpose of antistatic.

Answer: What is the working principle of antistatic agent and what are the main components of antistatic agent? Antistatic agents in this market can be classified into wash-resistant antistatic agents and ordinary antistatic agents according to their functions.

Washable antistatic agents include: Nalute antistatic agents.

Common antistatic agents are: Colcoat antistatic agent, Polyflex antistatic agent and ACL antistatic agent.

The main difference between washable antistatic agents and ordinary antistatic agents is whether they are resistant to washing.

Nalut washable antistatic agent, rinsed with water, or wiped with a washing towel, will not lose its anti-static function.

Ordinary antistatic agents cannot be washed with water, and if they are rinsed with water or wiped with a damp cloth, they will lose their antistatic function.

Note: The antistatic agent mentioned here refers to the externally coated antistatic agent, commonly known as antistatic liquid.

Polymer permanent antistatic agent is a new type of antistatic agent researched and developed in recent years, which is a hydrophilic polymer. When it is blended with the polymer matrix, on the one hand, due to the strong movement ability of its molecular chains, it is convenient for protons to move between molecules, and conducts and releases the generated electrostatic charge through ionic conduction. On the other hand, the antistatic ability is manifested by its special dispersion form.

The results show that the polymer permanent antistatic agent is mainly a fine layered or ribbed distribution on the surface of the work-in-progress, constituting a conductive surface, and is almost spherical in the central part, forming the so-called "core shell structure", and using this as a channel to leak electrostatic charge. Because the polymer permanent antistatic agent is to reduce the volume resistivity of the material to achieve the antistatic effect, it does not completely rely on the surface water absorption, so it is less affected by the humidity of the environment.

The distribution of antistatic agents on the surface of plastic products must reach a certain concentration to show the antistatic effect, which is called the critical concentration. The critical concentrations of various antistatic agents vary depending on their composition and usage. The reason for this is that the single-molecule conductive layer formed by relying only on the orientation of hydrophilic groups in the air will not have a significant antistatic effect.

Only when the antistatic agent molecule is more than 10 layers on the surface, it will produce an excellent antistatic effect due to the orientation of the hydrophilic group.

What are the main ingredients of antistatic agents?

The main ingredient of antistatic agent, different brands of antistatic agent is different, some are ordinary antistatic agents, some are polymer antistatic agents.

Antistatic agent is a special additive added to plastic products and other materials or coated on the surface of products to reduce the surface resistance of products.

The main components of antistatic agents depend on what type of antistatic agent they are: permanent antistatic agents are mostly polymer types, polyoxyethylene types and other components. The non-permanent ones are cationic, anionic, amphoteric and non-ionic.

It varies according to the chemical composition. Antistatic agents can be divided into sulfuric acid derivatives, phosphoric acid derivatives, amines, quaternary ammonium salts, imidazoles and ethylene oxide derivatives, etc., according to whether the hydrophilic group in the antistatic agent molecule can be ionized, it is divided into ionic and non-ionic types. According to the type of addition, it is divided into internal type and coating type.

The antistatic agent and the raw material can be mixed evenly with the internal antistatic agent, and the externally coated antistatic agent can be diluted and sprayed directly on the surface of the product according to the needs. Nantong Leishang Chemical specializes in the production of antistatic agents, there are different antistatic agents, internal and external coating permanent non-permanent, transparent are available. Depending on what material you want to use and what different impedance requirements you want to use, the external coating can be done to the 2-4th power, 5-6th power, and the permanent glue adhesive antistatic agent is also available, which does not affect the adhesion.
