Abstract

The invention discloses an expandable type building fireproof coating and a preparation method thereof. The preparation method comprises the following steps: weighting unsaturated polyester resin andthen adding into a stirring reaction kettle; adding styrene, methyl ethyl ketone peroxide, cobalt naphthenate and liquid paraffin into the reaction kettle in turn while stirring, and then reacting while stirring for 20-40min; weighting expandable graphite, ammonium polyphosphate, pentaerythritol and melamine and then adding into a grinding mill for grinding; weighting filler and then adding into the grinding mill for grinding; pouring the filler and the mixture of ammonium polyphosphate, pentaerythritol and melamine into the stirring reaction kettle, and quickly stirring and mixing for 30-60min; adding auxiliaries and solvent, and then stirring and mixing again. According to the invention, different modified resins are stirred and mixed at different ratios, so that the fireproof time of the coating is prolonged, and meanwhile, the fireproof coating has anti-ultraviolet, antibacterial, sterilizing and anticorrosion effects, and the service life of the coating is prolonged.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to an intumescent building fireproof coating and a preparation method thereof. Background technique [0002] In terms of fire prevention mechanism, fire retardant coatings are generally divided into two types: intumescent and non-intumescent. Non-intumescent fire retardant coatings rely on their own high flame retardancy or non-combustibility to achieve the purpose of flame retardant and fire prevention. To achieve a good fire prevention effect, it must be coated very thickly, and a large amount of halogen, nitrogen, phosphorus and other flame retardants are added to produce Lots of toxic gas. Intumescent fireproof coating means that the coating film expands when heated to form a honeycomb carbonized layer, which isolates the heat of the flame and reduces or slows down the transfer to the substrate. A series of physical and chemical reactions that occur during fire prev...
