Embodiment 1

[0013] Add phosphoric acid into the reactor, heat and stir, add oxides, and when the test solution is transparent, obtain inorganic phosphate at 80 degrees Celsius. 51 grams of amino acid sodium phosphate resin, 36 grams of inorganic phosphate, 5 grams of tricresyl sulfate, 4 grams of glyceryl stearate, and 4 grams of polyurethane film-forming agent were filtered with a standard sieve, and then uniformly mixed.

Embodiment 2

[0015] Add phosphoric acid into the reactor, heat and stir, add oxide, when the test solution is transparent, prepare inorganic phosphate at 80°C. 50 grams of amino acid sodium phosphate resin, 38 grams of inorganic phosphate, 4 grams of tricresyl sulfate, 4 grams of glyceryl stearate, and 4 grams of polyurethane film-forming agent were filtered with a standard sieve, and then uniformly mixed.

Embodiment 3

[0017] Add phosphoric acid into the reactor, heat and stir, add oxides, and when the test solution is transparent, obtain inorganic phosphate at 80 degrees Celsius. 49 grams of amino acid sodium phosphate resin, 38 grams of inorganic phosphate, 5 grams of tricresyl sulfate, 4 grams of glyceryl stearate, and 4 grams of polyurethane film-forming agent were filtered with a standard sieve, and then uniformly mixed.

Abstract

The invention discloses a transparent fireproof coating which comprises the following components in percentage by mass: 40-55% of amino acid sodium phosphate resin, 30-38% of inorganic phosphate, 4-6% of thickening agent, 3-5% of dispersing agent and 3-5% of film forming agent. According to the transparent fireproof coating disclosed by the invention, the amino acid sodium phosphate resin and the inorganic phosphate are used as base materials, the amino acid sodium phosphate resin also serves as a foaming agent and a charring agent, and the inorganic phosphate also serves as a catalytic dehydrating agent; and by adding the dispersing agent and the film forming agent, the dispersity and film forming property of the system are improved. The coating disclosed by the invention is transparent liquid and can be self-dried at normal temperature; and the coating has good flame resistance and thermal insulation as well as an obvious fireproof effect.

Description

[0001] technical field [0002] The invention relates to a paint with fireproof function, in particular to a transparent fireproof paint. Background technique [0003] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. Generally speaking, fire retardant coatings can be divided into non-expandable and intumescent types. The first is to form a glaze-like protective layer when exposed to fire, which prevents oxygen from contacting the substrate and prevents heat from radiating and conducting to the substrate. Fireproof, but due to its decorative and fireproof defects, it is not suitable for combustible substrates. [0004] The latter expands and foams when exposed to fire, forming a dense cellular foam layer. The foam layer has low thermal conductivity, which delays the burning ...
