Embodiment 1

[0023] Based on 100kg of product, 12kg of cellulose ether, 10kg of FEVE fluorocarbon resin, 15kg of glass beads, 20kg of pigment, 7kg of ammonium polyphosphate, 6kg of curing agent, 25kg of phenolic propane epoxy resin, 5kg of pentaerythritol, 5kg of expanded graphite, and the rest is solvent . Solvent a is preferably isopropyl acetate, and solvent b is preferably n-butanol. The curing agent is dimethylaniline.

[0024] Step 1: Mix glass beads, pigments, ammonium polyphosphate, curing agent, and solvent a, and after stirring evenly, perform high-speed grinding to a fineness of 15-20 μm to obtain a color paste;

[0025] Step 2: Mix cellulose ether, FEVE fluorocarbon resin, phenolic propane epoxy resin and solvent b, stir evenly, add the color paste prepared in step 1, disperse at high speed for 15-20 minutes, and filter, which is the present invention product.

Abstract

The invention discloses a fire retardant coating, which is characterized by comprising the following materials in percentage by mass: 10-20% of cellulose ether, 10% of FEVE fluorocarbon resin, 15% of glass beads, 15-30% of pigment, 5-10% of ammonium polyphosphate, 3-8% of a curing agent, 10-30% of phenol propane epoxy resin, 4-8% of pentaerythritol, 4-8% of expanded graphite and the balance being a solvent. The product disclosed by the invention is flame-retardant or non-inflammable, so that a protected substrate is kept from direct contact with air, thus delaying firing and combustion speed of an object; and besides the performance of being flame-retardant or non-inflammable, the fire retardant coating additionally has a relatively low heat conductivity coefficient, and can delay transmission of flame temperature to the protected substrate.

Description

technical field [0001] The invention relates to the field of building materials, and is a fireproof coating. Background technique [0002] With the extensive application of organic synthetic materials, their flammability has become increasingly prominent. Flame-retardant organic polymers containing halogens often lead to deterioration of physical properties of materials, shortened service life, and increased prices. The method of coating fireproof paint on its surface for fireproof protection can not only maintain the excellent performance of the original organic synthetic material, but also be economical and applicable. The application of fire retardant coatings on organic synthetic materials also has broad prospects. In addition, ordinary steel loses its structural strength when heated to about 540°C. Concrete structures are also prone to cracking and disintegration under the action of high-temperature flames. Therefore, the fire protection of steel structures and ...
