Environment-friendly fire retardant coating for evanescent mode

Abstract

The invention discloses an environment-friendly fire retardant coating for an evanescent mode. The coating is characterized by comprising the following raw materials by weight: 30-40 parts of aqueous mixed resin, 8-10 parts of acrylic acid, 3-5 parts of titanium dioxide, 2-4 parts of tricresyl phosphate, 3-5 parts of wood fiber, 0.4-0.6 part of antimony oxide, 3-5 parts of chlorinated paraffin, 2-4 parts of slaked lime, 0.5-0.8 part of maleic anhydride, 2-3 parts of a charring agent, and 15-20 parts of MADE high-boiling-point environment-friendly solvent. The fire retardant coating employs acrylic acid, antimony oxide and slaked lime to reach high foaming efficiency and uniform foaming; the delicate product coating can resist high temperature baking to play the fire prevention and heat insulation effect; the aqueous mixed resin and MADE high-boiling-point solvent environment-friendly hybrid formulation is employed, so that the product is non-toxic and low-odor and protects the environment and human security, and the coating has excellent weather resistance, chemical corrosion resistance and long service life.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an environment-friendly fireproof coating used for lost foam. Background technique [0002] Fire-resistant coatings are applied to the surface of combustible substrates to change the combustion characteristics of the material surface and retard the rapid spread of fire; or applied to building components to improve the fire-resistant limit of the special coatings, called fire-resistant coatings. Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. There are many types of fire retardant coatings, but according to the use of fire retardant coatings and the coating thickness of fire retardant coatings, they are generally divided into decorative coatings and steel structure fire retardant coati...

Problems solved by technology

Ordinary fire retardant coatings have poor texture

Due to the special structure of the lost foam working surface and the special working environment, it is difficult for ordinary fireproof coatings to meet the requirements during work.
