Fireproof flame-retardant paint composition

Abstract

The invention discloses a fireproof flame-retardant paint composition which is prepared from the following components in parts by weight: 30-50 parts of alkyd resin, 10-30 parts of polyurethane paint, 5-15 parts of methyl isobutyl ketone, 5-10 parts of chlorinated paraffin, 3-8 parts of thickener, 5-10 parts of ethanol aether acetate, 1-3 parts of cyclohexanone and 10-15 parts of coal tar. The paint composition is modified by an epoxy resin. The epoxy resin contains the hydroxy group, and the epoxy group and ether group with medium molecular weight above have polarity, so the paint composition has very high adhesive force, optimal alkali resistance, favorable acid resistance, small film-forming contractility (within 1%), favorable stability and favorable insulativity, and thus, is called chemical alloy. After adopting the epoxy resin, the adhesive force of the paint is greatly improved from Grade 3 to Grade 1-2, and the paint film has high corrosion resistance, high impact resistance and high hardness.

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 ...
