Thermo-setting acrylic-acid emulsion, its preparing method and paint containing same

Abstract

This invention discloses a thermoset crylic acid latex and its preparation method and a corrosion resistant bottom coat containing such latex and used in the Al fins of the heat converter of air conditioners, in which, said latex includes a crylic acid kind monomers, an ionic vinyl monomers, an ethene monomers, a vinyl silane coupler, a crosslink monomers, a surface active agent and an initiator to be got by seed latex and semi-continuous drop technology. Said bottom coat includes said thermoset crylic acid latex, water-base coating resin, water-base cross-linker, booster solvent, neutralization agent, a water-base adhesive force accelerant, a catalyst and water.

Description

technical field

[0001] The invention relates to the field of coatings, in particular to a thermosetting acrylic emulsion and a preparation method thereof, and a corrosion-resistant primer containing the emulsion and used for aluminum fins of air-conditioning heat exchangers. Background technique

[0002] With global warming, the market demand for various types of air conditioners is increasing; and the situation of energy shortage has prompted the development of air conditioners in the direction of lightweight, miniaturization, and high energy efficiency. One of the effective measures to realize the lightweight, miniaturization and high energy efficiency ratio of the air conditioner is to reduce the thickness of the aluminum fins of the air conditioner heat exchanger, reduce the distance between the aluminum fins, and increase the heat transfer area per unit weight of the heat exchanger . At present, the thickness of aluminum foil used for aluminu...
