Abstract

The invention provides a hot-shrinkable material spraying temperature indicating paint and a preparation method, the temperature indicating paint comprises the following components: organic amino acid, organic benzoic acid, an acrylic acid adhesive agent, a film forming agent, an organic diluent and color powder. The hot-shrinkable material spraying temperature indicating paint is sprayed on the hot-shrinkable material surface, and is dried to form a film, and has the advantages of fast film forming time, smooth surface and good toughness; the roasting temperature can be accurately indicated through variable color, the roasted position and unroasted position can be obviously and effectively indicated; and the roasting time of the hot-shrinkable material can be effectively controlled through color changing time.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a thermo-indicating paint sprayed on heat-shrinkable materials and a preparation method thereof. Background technique [0002] In the usual application of heat shrinkable materials, most of the baking time is determined based on personal experience. This method has different levels of operation, which seriously affects the use of heat shrinkable materials. If the baking is not in place, it will cause incomplete shrinkage of the heat shrinkable material; or excessive baking will cause damage to the heat shrinkable material. Contents of the invention [0003] The invention provides a temperature-indicating paint sprayed on a heat-shrinkable material and a preparation method thereof, which can accurately indicate the baking temperature through discoloration, and after spraying on the surface of the heat-shrinkable material, self-drying film is formed, the film-forming time is fast...
