Abstract

The invention relates to a fireproof coating, a wood hanging plate and a preparation method thereof, and the fireproof coating is mainly prepared from the following raw materials in parts by weight: 18-22 parts of amino resin; 4-6 parts of ethylene glycol butyl ether; 0.05-0.2 part of alcohol ester-12; 0.05-0.2 part of benzyl alcohol; 0.1-0.2 part of a waterborne polyurethane dispersion body; 1-3 parts of an ethylene-ethylene acetic acid copolymer; 3-7 parts of polysiloxane; 5-8 parts of phosphorus-nitrogen phosphate; 4-8 parts of guanidine phosphate; 8-12 parts of pentaerythritol; and 20-40 parts of water. Meanwhile, the invention further discloses the fireproof coating prepared under the action of stirring twice and ultrasound. Through mutual cooperation of the raw materials and under the action of the preparation method and process parameters, the prepared fireproof coating has better dispersion uniformity and flowability, can be coated on the surface of a wooden hanging plate at one time, greatly simplifies the construction period, realizes industrial production, and can ensure that the coating has higher fireproof performance.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a fireproof coating, a wooden hanging board and a preparation method thereof. Background technique [0002] Wooden hanging boards are wooden finished decorative hanging boards, which are widely used in villas, multi-storey or high-rise apartment buildings, office buildings and entertainment places for wall installation and decoration. Performance is also an important indicator for evaluating the overall quality of wood siding. [0003] At present, fire-resistant coatings used to coat wooden sidings are research hotspots at home and abroad. Fire-resistant coatings not only need to have a good flame-retardant effect, but also be suitable for industrial coating processes. Some fire retardant coatings have good flame retardant effects, but they need to be painted by hand many times, and they cannot be applied to wooden hanging boards by coating machines.
