Problems solved by technology

However, most of the magnesium-based flame retardants and magnesium-based flame retardants in the prior art are organic flame retardants, and the preparation cost is high. Especially when used in public environments or industries, the dosage is large, which leads to increased costs and increases the cost of industrial and public environments. construction cost

preparation example Construction

[0047] A preparation method of magnesium-based flame retardant, said method comprising the following steps:

[0048] 1) Preparation of magnesium-based suspension:

[0049] (a) Take an appropriate amount of magnesium oxide and an organosilane coupling agent into the reaction tank, add a sodium silicate solution into the reaction tank and heat and stir to obtain a magnesium-based suspension;

[0050] (b) filtering the magnesium-based suspension to remove impurities to obtain a pure magnesium-based suspension;

[0051] 2) Preparation of inorganic flame retardant:

[0052] (c) After the diatomite and hydrated silica are pulverized by a ball mill, soaked in water to remove impurities, dehydrated and dried, and then ground into a powder mixture;

[0053] (d) adding an acidic solution to the powder mixture, stirring for 2.5 hours, filtering, removing the precipitate, retaining the acidic solution, adjusting the pH value to 6-6.5, and obtaining a weakly acidic mixed liquid;

Abstract

The invention discloses a formula of a magnesium-based flame retardant. The formula comprises the following components in parts by weight: 5-8 parts of magnesium oxide and 3-5 parts of an organic silane coupling agent; 15-25 parts of hydrated silica, 20-28 parts of diatomite, 5-10 parts of aluminum hydroxide particles, 6-11 parts of silicon dioxide particles and 45-55 parts of sodium silicate. The magnesium-based flame retardant is prepared by preparing the magnesium-based suspension and the inorganic flame retardant and finally mixing the components, and the magnesium-based suspension and the inorganic flame retardant are mixed so that the flame retardant not only has the advantages of low smoke, low toxicity, no halogen, good stability, low price and the like of the inorganic flame retardant, but also has the advantages of high thermal stability, corrosive gas is not easily generated during combustion, and the flame retardant is suitable for production of plastics such as polypropylene with higher processing temperature.

Description

technical field [0001] The invention belongs to the technical field of flame retardant preparation, and in particular relates to a magnesium-based flame retardant formula and a preparation method. Background technique [0002] Flame retardant, a functional additive that imparts flame retardancy to flammable polymers, is mainly designed for the flame retardant of polymer materials; there are many types of flame retardants, which are divided into additive flame retardants and reaction type flame retardant. Additive flame retardants are added to polymers by mechanical mixing to make polymers flame retardant. At present, additive flame retardants mainly include organic flame retardants and inorganic flame retardants. Halogenated flame retardants (organic flame retardants) chlorides and organic bromides) and non-halogenated. Organic is some flame retardants represented by bromine, phosphorus nitrogen, nitrogen and red phosphorus and compounds, and inorganic is mainly antimony t...
