Abstract

The invention discloses a stainless steel PCM (Pre-Coated Metal Steel) plate and a production process thereof and relates to the technical field of metal plates for household electric appliance shells. According to the technical scheme, the stainless steel PCM plate is characterized by comprising a metal substrate, wherein a chemical treatment layer, a prime coat layer, a finish coat layer and a PE (Polyethylene) membrane layer are sequentially arranged on one side of the metal substrate; a back coat layer is arranged on the other side of the metal substrate; a finish coat comprises the following components in parts by weight: 40-50 parts of an aqueous polyester resin, 20-30 parts of an amino resin, 3-5 parts of triethanolamine, 25-35 parts of butyl acetate, 6-10 parts of cellulose acetatebutyrate, 10-15 parts of butyl cellosolve, 1-2 parts of a leveling agent, 2-3 parts of an organic silicon hand feeling agent and 1-2 parts of a matte agent. As the finish coat with the hand feeling agent and the matte agent is smeared on the metal substrate, the coldness and the metal feeling of the metal substrate can be degraded, the tough feeling of the PCM plate can be gentle, and the appearance attractiveness of the PCM plate can be improved.

Description

technical field [0001] The invention relates to the technical field of metal plates used for housings of household appliances, more specifically, it relates to a stainless steel PCM plate and a production process thereof. Background technique [0002] Stainless steel PCM plate, also known as PCM color steel plate, is a steel plate with an organic coating, which can be used for the decoration of household appliances such as refrigerator door panels, side panels, back panels, washing machine cabinets, water heater tubs, and microwave oven casings. . In the prior art, the patent application document with application number 201810904754.8 discloses a water-based PCM steel plate and its manufacturing process. The water-based PCM steel plate of the present invention includes a metal substrate, and the surface of the metal substrate is coated with a water-based paint layer. The water-based PCM steel plate manufacturing process of the present invention comprises the following step...
