Abstract

The invention discloses a heat insulation coating for a thick steel plate. The heat insulation coating comprises the following components in percentage by weight: 15%-30% of epoxy resin, 0.1%-2% of 2,4,6-tris-(dimethylaminomethyl) phenol, 0.05%-2% of expoxy resin curing agent, 0.01%-15% of alpha terpene resin, 40%-65% of mixed acid methyl ester, 0.01%-1% of chlorendic acid, 0.01%-1% of zinc oxide and 15%-30% of anti-settling powder. The heat insulation coating provided by the invention can be widely applied to the heat insulation of ship decks, ship bodies, refrigerator cars, refrigeration houses, trains and the like and has the effects of saving energy, power and materials on a large scale.

Description

technical field [0001] The invention relates to a thermal insulation coating for thick steel plates. Background technique [0002] Ship decks, trains, and refrigerated truck shells are all made of metal, which are closed thick steel plate products. Their thermal insulation performance is poor, and they are greatly affected by the external environment temperature. It maintains the proper temperature for its internal cargo, so if you can find a way to improve the insulation performance of its surface, you can save a lot of energy. It is a convenient and effective method to coat the surface with a layer of heat-insulating super-insulation coating to improve the thermal insulation coefficient of the surface. But currently on the market, there is no heat-insulating coating specially applied to this type of thick steel plate both at home and abroad. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and to provi...
