Abstract

The invention discloses an electric heater aluminum plate used heat sealed paint and it's preparing and coating method. The paint is formed by ternary trichloroacetic resin with carboxyl, n-butyl methacrylate, dioctyl phthalate, butanone and acetic ether; the preparing method is that first preparing for the ternary trichloroacetic resin with carboxyl, adding the raw material into the high speed dispersion machine to stir and dissolve them until the resin dissolves to obtain the hest sealed paint. The coating art is that it uses acetic ether to dilute the heat sealed paint and adds blue paint into it to stir them; it adopts net roller coating method to coat it and solid it.

Description

1. Technical field [0001] The invention relates to a heater aluminum foil material for a refrigerator, a heating floor or a toilet and a manufacturing method thereof, in particular to a heat-sealing paint for a heater aluminum foil and a preparation and coating method thereof. 2. Background technology [0002] With the development of the refrigerator industry and the improvement of people's living standards, the defrosting technology of refrigerators has been further developed. Almost all refrigerators manufactured in foreign countries (such as Japan) use heater aluminum foil to form heating components to replace the old-fashioned external auxiliary resistance belt. Or aluminum foil, heating wire, and aluminum foil sandwich heaters to realize electronic defrosting, and the safety performance is fully guaranteed. The aluminum foil for the heater is coated with a layer of polyvinyl chloride thermoplastic heat-sealing coating on the surface of the light aluminum foil. Form hea...
