Abstract

The invention discloses high-temperature resistant alkyd paint, which is prepared by using a high-temperature resistant alkyd resin, a 582-2 amino resin and a drier. The alkyd resin produced by the invention is light-colored, never becomes yellow, has excellent flexibility, is low in reaction temperature and short in production period, and is capable of reducing reaction time by 2 hours and saving 10 percent of energy. The high-temperature resistant alkyd paint prepared by using the alkyd resin never becomes yellow and never bubbles after being used for a long time under a 200 DEG C high-temperature environment, has an impact strength more than 50Kg / cm, has an insulating heat resistance level of B-level (130 DEG C), and can be widely applied to soaking and insulating electrical equipment and coils, such as small and medium size motor coils, transformers, rectifiers, and the like.

Description

technical field [0001] The invention relates to the technical field of heat-resistant paint, in particular to a high-temperature-resistant alkyd paint. Background technique [0002] The existing alkyd resins for amino alkyd quick-drying dipping paints are mostly prepared from soybean oil supplemented with other raw materials. This resin is usually formulated with butyl-etherified melamine-formaldehyde resins and other raw materials to form paints, but this This kind of coating will turn yellow and become brittle when it is baked and dried at high temperature and used in a long-term high temperature environment, which will affect the insulation, oil resistance and arc resistance. [0003] Also have the alkyd resin that adopts coconut oil to prepare, although it has good weather resistance, the characteristics of not yellowing when baking, the impact resistance of paint film is not good. Contents of the invention [0004] The technical problem to be solved by the present in...
