preparation example Construction

[0037] The preparation method for preparing the above-mentioned wood structure flame retardant coating, the steps are as follows:

[0038] A water phase preparation: take materials according to the weight ratio of each component, mix water, additives and titanium dioxide evenly, then add water-based film-forming matrix, intumescent flame retardant and graphene-like substances, and stir evenly;

[0039] B flame retardant powder additive preparation: according to the weight ratio of each component, methoxy acrylic resin, P-N composite flame retardant, inorganic filler, aluminum hydroxide and antimony halide are mixed and stirred evenly;

[0040] C Finished product preparation: Mix component A and component B according to the weight ratio, and sieve and discharge after grinding.

[0041] Among them, when stirring in the preparation of component A, keep the rotation speed at 1000-1200r / min; when stirring in the preparation of component B, keep the rotation speed at 800-1000r / min; ...

Embodiment 1

[0042] Embodiment 1: A kind of wooden structure flame retardant coating, comprises the following components in parts by weight: 100 parts of aqueous film-forming substrates, 200 parts of intumescent flame retardants, 20 parts of rutile titanium dioxide, 0.03 parts of graphene, additives 1 part, 200 parts of water, 50 parts of flame retardant powder additive.

Abstract

The invention discloses a wood structure flame-retardant coating and a preparation method thereof. The wood structure flame-retardant coating is prepared from the following components in parts by weight: 100 parts of a water-based film-forming matrix, 200 to 250 parts of an intumescent flame retardant, 20 to 30 parts of titanium dioxide, 0.01 to 5 parts of a graphene substance, 1 to 2 parts of an auxiliary agent, 200 to 250 parts of water and 50 to 80 parts of a flame-retardant powder additive, wherein the flame-retardant powder additive comprises methoxy acrylic resin, a P-N composite flame retardant, an inorganic filler, aluminum hydroxide and antimony halide. Titanium dioxide is attached to the surface of a carbon layer after being combusted, the strength of a carbonized layer is improved, heat conduction is isolated, the P-N composite flame retardant has a good phosphorus-nitrogen synergistic effect, the flame retardant effect is good, the P-N composite flame retardant can expand in a fire disaster, a uniform and compact carbonaceous foam layer is formed, oxygen is isolated, and the P-N composite flame retardant has good heat insulation performance due to the fact that the texture of the P-N composite flame retardant is loose. The rate of transferring heat to a protected base material can be delayed, and an efficient fireproof and heat-insulating protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a wood structure flame retardant coating and a preparation method thereof. Background technique [0002] As a building material, wood has the characteristics of light weight, high strength, beautiful appearance, and good processing performance, and has been favored by people since ancient times. Compared with the reinforced concrete or brick-and-tiled houses that are widely used now, wooden houses have the following advantages: (1) wood is a natural and healthy material, and wood materials are renewable, recyclable, and environmentally friendly; (2) Wooden structure has good resistance to instantaneous impact and periodic fatigue damage; (3) the use of wooden structure houses can protect the land; (4) the construction of wooden structure buildings has short construction period, convenient maintenance, flexible layout and shape, and maintenance and maintenance. ...
