Problems solved by technology

[0003] At present, most of the water-based wood flame retardants on the market use water-soluble ammonium polyphosphate or ammonium polyphosphate type I with a low degree of polymerization. Therefore, it is widely used in the flame retardant of wood materials, but this kind of low-polymerization flame retardant is easy to migrate and precipitate in a humid environment, producing white flowers, which affects the appearance of wood; at the same time, the precipitation of white flowers also reduces the effective content of flame retardants. Cost, which in turn causes its flame retardant performance to be affected

Embodiment 1

[0029] Put 7500g of 50% mass fraction of amino trimethylene phosphonic acid ATMP aqueous solution into the reactor, add 4250g of 25% mass fraction of ammonia water, mix uniformly and fully react and cool to room temperature to obtain the reaction solution, and mix 350g of ethylene glycol Amine, 250g of sodium hydroxide and 75g of surfactant sodium dodecylbenzenesulfonate were added to the liquid and stirred evenly to obtain 12425g of flame retardant for wood. The flame retardant for wood obtained in this example consists of an aqueous solution containing ATMP, ammonia, ethylenediamine and a surfactant.

Embodiment 2

[0031] Put 7500g of 61% mass fraction of hydroxyethylene diphosphoric acid HEDP aqueous solution into the reactor, add 4500g of 25% mass fraction of ammonia water, mix uniformly and fully react and cool to room temperature to obtain the reaction solution, then add 350g of trimethylamine , 250g of potassium hydroxide and 75g of surfactant sodium dodecylbenzene sulfonate were added to the liquid and stirred evenly to obtain 12675g of fire retardant for wood. The flame retardant for wood obtained in this example is composed of HEDP, ammonia water, trimethylamine, potassium hydroxide and surfactant aqueous solution.

Embodiment 3

[0033] The aminotrimethylene phosphonic acid (ATMP) aqueous solution of the mass fraction 50% of 7500g is put into reactor, the ammoniacal liquor of the mass fraction 25% that adds 4250g wherein mixes evenly and fully reacts and cools to room temperature and obtains reaction solution, then 200g Aniline, 150g catecholamines, 125g aluminum hydroxide, 125g magnesium hydroxide and 75g surfactant sodium dodecylbenzenesulfonate were added to the liquid and stirred evenly to obtain 12425g fire retardant for wood. The fire retardant for wood obtained in this embodiment is composed of amino trimethylene phosphonic acid (ATMP), ammonia water, aniline, catecholamine, aluminum hydroxide, magnesium hydroxide and surfactant aqueous solution.

Abstract

The invention discloses a water-based transparent wood flame retardant for inhibiting white bloom as well as a preparation method and application thereof. The water-based transparent wood flame retardant is mainly prepared from the following raw materials in parts by weight: 15-40 parts of a phosphorus flame retardant solution, 7-15 parts of an ammonia water solution, 2-15 parts of amine, 1-10 parts of hydroxide and 0.5-1.5 parts of a surfactant. According to the water-based transparent flame retardant disclosed by the invention, the interface action between the flame retardant and wood is increased by adding amine substances, the migration resistance between the flame retardant and the wood is improved, and active ingredients in the flame retardant cannot be migrated and separated out, so that the generation of white bloom is inhibited, and the problem that a low-polymerization-degree flame retardant is easy to migrate and separate out in a humid environment is solved; the effect is guaranteed, and the attractiveness of the wood is not affected. In addition, hydroxide is added into the flame retardant, so the problem that the viscosity of a water-based flame retardant is increased when the water-based flame retardant is repeatedly used is solved, energy is saved, and consumption is reduced.

Description

technical field [0001] The invention relates to the field of flame retardants, in particular to a water-based transparent wood flame retardant for suppressing white blooms and a preparation method and application thereof. Background technique [0002] In today's society, with the development of the times, a variety of new building structural materials and decorative materials have been produced. However, due to the unique and excellent characteristics of wood, wood veneer gives people a special and beautiful look and feel, which is the best choice for other decorative materials. Nothing can compare to it. Therefore, wood has always maintained an important position in construction engineering, especially in the field of decoration. At the same time, wood has the advantages of humidity control, noise reduction, and low heat conduction. However, wood is a material composed of cellulose as a matrix, which is extremely flammable. Studies have shown that the temperature of a woo...
