Fire retardant coating composition

Abstract

The invention discloses a fire retardant coating composition. The fire retardant coating composition comprises the following components by weight percentage: 40-50 parts of alkide resin, 10-20 parts of epoxy resin, 5-15 parts of silicon dioxide particles, 5-15 parts of chlorcosane, 3-5 parts of a thickener, 5-10 parts of butyl glycidyl ether, and 1-3 parts of cyclohexanone, and 10-20 parts of acetylsalicylic acid. The epoxy resin is used for modification. Since the epoxy resin contains hydroxyl radicals, the polarity of epoxy radicals and ether radicals with intermediate molecular weight is high, the adhesion force is very strong, the basicity resistance is optimal, the acid resistance is better, the film forming contractility is not greater than 1 percent, and the stability and the insulation performance are very high, so that the fire retardant coating composition is called chemical alloy. After adopting the epoxy resin, the adhesion force of a coating is greatly improved from a level 3 to levels 1-2, the corrosion resistance and impact force resistance are strong, and the strengthening hardness is good.

Description

technical field [0001] The invention relates to the field of coatings, in particular, the invention relates to a fireproof and flame retardant coating composition. Background technique [0002] At present, all kinds of fireproof coatings, whether solvent-based or water-based, have a common defect: poor water resistance, and can only be used indoors, rarely used outdoors, because the paint film will bulge when exposed to moisture or water (snow and rain). Bubbles, the paint film will be damaged over time, affecting the protection life, and what is more serious is a fire, because the failure or loss of fire-resistant fire-retardant materials in the paint film will affect the rescue. The defects of the existing fireproof coatings are: poor water resistance, can only be used in indoor occasions, not fireproof, poor adhesion, and poor strength resistance. The main reason is that most of the flame retardants and carbon-forming skeleton agents in the formula are water-soluble and ...
