Conductive agent for double-component polyurethane paint and PU diluent

Abstract

The invention discloses a conductive agent for a double-component polyurethane paint. The conductive agent is prepared from the following raw materials in parts by weight: 10-20 parts of a phosphorus-containing nonionic surfactant, 10-20 parts of an alcohol ether nonionic compound, 30-60 parts of propylene glycol methyl ether, and 10-30 parts of ethylene glycol monoethyl ether acetate. The invention also discloses a PU diluent adopting the conductive agent for the double-component polyurethane paint. The PU diluent is prepared from the following raw materials in parts by weight: 0-20 parts of the conductive agent for the double-component polyurethane paint, 10-30 parts of xylene, 20-40 parts of acetic ester, 5-20 parts of PMA, and 0-10 parts of ethylene glycol butyl ether. The conductive agent has good miscibility and good conductivity effect; especially after the double-component paint is prepared, the double-component paint has long and stable activation period; the conductive agent does not contain diacetone alcohol, butyl alcohol and ionic surfactants, but contains the nonionic surfactant, thereby not affecting crosslinking; and the conductive agent has remarkable conductive effect due to relatively strong polarity.

Description

technical field [0001] The invention relates to a conductive agent, in particular to a conductive agent and a PU diluent for two-component polyurethane paint. Background technique [0002] Polyurethane coatings, that is, polyurethane paints, contain a considerable amount of urethane bonds in the paint film, and are coatings that contain a considerable amount of urethane bonds in the paint film. [0003] The two-component polyurethane paint is divided into two components, A and B, which are stored separately. The main paint contains hydroxyl groups, and the curing agent generally contains isocyanate groups. When used, the components A and B are mixed and coated to make the isocyanate react with the hydroxyl groups to form polyurethane polymers. thing. Two-component polyurethane (PU) has a wide range of uses, because of its superior chemical resistance, weather resistance, toughness, and excellent decoration, it is widely used in hardware, auto parts, leather, and wood.

Problems solved by technology

[0007] The present invention overcomes the shortcomings in the prior art, and provides a conductive agent and PU diluent for two-component polyurethane paint, which solves the problem of rapid increase in viscosity due to the use of conductive agent during PU paint coating, making the Two-component polyurethane paint can also be painted electrostatically, which saves a lot of paint and costs. It can be more environmentally friendly without alcohol and ketones, overcomes the environmental risks brought by ketones and alcohols, reduces environmental pollution, and has significant economic benefits. and social benefits
