Which is the best antistatic agent? Advantages and disadvantages of anionic antistatic agents

If you want to know which antistatic agent is better, you must first find out what antistatic agents are on the market, and the antistatic agent mentioned here mainly refers to the external antistatic agent, or liquid antistatic liquid, that is, antistatic liquid. In the Chinese market, the manufacturers of externally coated antistatic agents are: Nalut antistatic agent, Baolifu antistatic agent, ACL antistatic agent and Colcoat antistatic agent.

The antistatic agents of these manufacturers are good, and the effects are not bad, so if you want to buy antistatic agents, you should find these manufacturers.

NAIR antistatic agent is a wash-resistant antistatic agent, that is, rinsing with water or wiping with a damp towel will not lose its antistatic function. The antistatic agent of other manufacturers is a traditional antistatic agent, which is not resistant to washing, and will lose its antistatic function when rinsed with water or wiped with a wet towel.

Let's take a look at some of the properties of common 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.

It is a substance that can reduce the surface resistance and volume resistance of materials or products, moderately improve conductivity, and prevent the accumulation of static electricity.

Commonly used polar groups (i.e., hydrophilic groups) are: carboxylic acid, sulfonic acid, sulfuric acid, phosphoric acid anions, amine salts, quaternary ammonium cations, and -oh, -o- and other groups, commonly used non-polar groups (i.e., lipophilic groups or hydrophobic groups) are: alkyl groups, alkyl aryl groups, etc.

Externally coated antistatic agent, surfactant, mixed antistatic agent, polymer permanent antistatic agent, cationic antistatic agent, anionic antistatic agent, non-ionic antistatic agent, antistatic agent is used in two ways: coating method and blending method. The coating method has the advantages of quick effect, low material consumption, and low heat resistance requirements for antistatic agents, but the antistatic effect cannot be lasted, and the antistatic agent coating will disappear after washing and rubbing. The blending method has the advantages of washing resistance, friction resistance, long-lasting antistatic effect, and simple use.

e.Water-soluble products, drying time is the same as water.

f.Bactericidal formulation.

g.Prevents dust adsorption.

h.Long-term storage does not expire (no expiration date).

i.It is still effective in dry environments with a relative humidity of less than 15%.

1. The mechanism of action of externally coated antistatic agents.

When this type of antistatic agent is added to water, the hydrophilic group in the antistatic agent molecule is inserted into the water, and the lipophilic group extends to the air. When the polymer material is impregnated with this solution, the lipophilic group in the antistatic agent molecule is adsorbed on the surface of the material. After impregnation, drying, on the surface of the polymer material after removing the water, the hydrophilic groups in the antistatic agent molecules are arranged towards the air side, which is easy to absorb environmental moisture, or combines with the moisture in the air through hydrogen bonding to form a monomolecular conductive layer, so that the generated electrostatic charge quickly leaks and achieves the purpose of antistatic.

2. Mechanism of action of surfactant internal mixed antistatic agent.

In the process of polymer material molding, if it contains a sufficient concentration of antistatic agent, when the mixture is in a molten state, the antistatic agent molecule forms the most dense orientation arrangement at the interface between resin and air or resin and metal (machinery or mold), in which the lipophilic group extends to the inside of the resin, and the hydrophilic group extends to the outside of the resin. After the resin is cured, the hydrophilic groups on the molecules of the antistatic agent are arranged towards the air side to form a single molecular conductive layer. In processing and use, stretching, friction and washing will lead to the defect of the molecular layer of the antistatic agent on the surface of the material, and the antistatic performance will also decline.

However, unlike the externally coated antistatic agent, after a period of time, the antistatic agent molecules inside the material will continue to migrate to the surface, so that the defective part can be restored, and the antistatic effect is re-displayed. Because the above two types of antistatic agents are by absorbing environmental moisture and reducing the surface resistivity of the material to achieve the purpose of antistatic, they are more dependent on environmental humidity. Obviously, the higher the ambient humidity, the stronger the water absorption of the antistatic agent molecules, and the more significant the antistatic properties.

3. The mechanism of action of polymer permanent antistatic agent.

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. Studies have shown that:

The polymer permanent antistatic agent is mainly a fine layered or rib-like distribution on the surface of the work-in-progress, constituting a conductive surface layer, and is almost spherical in the central part, forming the so-called "core shell structure", and uses 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.
