Abstract

The invention provides an instrument cabinet paint with good heat dissipation, which is characterized in that the product is prepared by the following raw materials by weight: 43-46 parts of E-44 epoxy resins, 16-19 parts of cis butenedioic anhydride, 1-2 parts of N-methylolacrylamide, 10-14 parts of vermiculite powder, 10-12 parts of aluminium nitride powder, 1-2 parts of ethylenebis(stearamide), 2-5 parts of tetrabutylammonium bromide, 1-2 parts of yttrium oxide, 17-19 parts of ethyl acetate, 1-2 parts of aminopropyltriethoxysilane, 9-12 parts of basic lead chromate silicate, 1-2 parts of triethanolamine, 24-28 parts of acrylic resin and 4-5 parts of auxiliary agents. The auxiliary agent provided by the invention can improve optical performance, thereby the paint is uniformly dispersed, and stability of paint is maintained and film forming effect is improved; the paint material of the present invention has the characteristics of fast drying, good decorative effect, easy construction, good yellowing resistance, good adhesion, etc. the formula contains aluminium nitride powder and has good heat radiation performance, and the product is suitable for cabinet with large caloric power.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an instrument cabinet paint with good heat dissipation and a preparation method thereof. Background technique [0002] Electrical, switch, and instrument cabinet (switch cabinet) is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The working environment of switchgear is diverse, and some environments are harsh. It is necessary to coat the surface of the cabinet with a paint layer to resist high temperature, cold, ultraviolet rays, and corrosion. However, the existing paint cannot meet the different requir...
