What are the product features of antistatic agents? What are the types of antistatic agents?

First answer the types of antistatic agents, the antistatic agents in the Chinese market can be divided into internal antistatic agents and external antistatic agents. Here we mainly introduce topical antistatic agents, which are commonly referred to as liquid antistatic agents or antistatic liquids.

Anti-static agents in the Chinese market include: Nalute, ACL, Polyfu and Colcoat, etc., Nalute anti-static agent is a washable anti-static agent, that is, rinsing with water or wiping with a wet towel will not lose the anti-static function. Other anti-static agents are traditional anti-static agents, which are not resistant to washing, and will lose their anti-static function when rinsed with water or wiped with a wet towel.

Features of antistatic agent products.

Antistatic agents are suitable for low-abrasion and smooth surfaces of any material.

The anti-static effect can last for weeks or months.

The use method is simple and diverse, it can be sprayed, rubbed, soaked, painted, etc.

Safe to use, non-toxic, odorless, non-combustible and non-corrosive.

No traces, no pollution, completely biodegradable.

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

Bactericidal formulation. Prevents dust adsorption.

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

It is still effective in dry environments with relative humidity below 20%.

1) Antistatic agent TM (chemical name: trihydroxyethylmethyl quaternary ammonium methyl sulfate): light yellow viscous oil, soluble in water, suitable for polyester and polyamide resin products. The dosage should not exceed 2% (mass fraction, the same below).

2) Antistatic agent SN (chemical name: octadecyldimethyl quaternary ammonium nitrate): brown-red oily viscous, decomposed above 180; Soluble in water, acetone, acetic acid and other solvents. It is mostly used in resins for PVC, polyester and polyethylene products, which can increase the conductivity of the surface of the products and eliminate the accumulation of static electricity after molding the products.

Do not exceed 2% in dosage.

3) ECH antistatic agent: alkyl amide non-ionic surfactant, light yellow waxy solid, melting point of 40 44. It is mainly used for resin for flexible and semi-rigid PVC film or sheet, and is an internal antistatic agent. The dosage is about the same.

It can be divided according to the aging period, or according to the industry, such as plastic antistatic, ink antistatic agent, polyurethane antistatic agent, rubber antistatic agent, etc.

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.
