Problems solved by technology

Conventional flame retardants with a single flame retardant effect often cannot meet the needs. Organic flame retardants have stable molecular group structure, low moisture regain, and migration resistance. The flame-retardant wood produced is not easy to breed mold and has low corrosion to metals. , but the biodegradability is poor, it is not very friendly to the environment, and the cost of raw materials is too high to be accepted by the market; although the cost of inorganic flame retardants is low, they are all made of strong acid and weak base salts or weak acid and weak base salts. The metal pressure tank has strong corrosion, which shortens the service life of the pressure tank. The flame-retardant wood produced is easy to regain moisture and migrate, and it is easy to breed mold, which has strong corrosion on metal components.

preparation example Construction

[0043] The second aspect of the present invention provides a method for preparing a halogen-free multi-effect wood flame retardant, which includes the following steps: according to the proportion, adding the flame retardant component and the anti-moisture agent into the horizontal mixing tank, and adding 30 to 50 Stir at a speed of rpm for 20-40 minutes, then add anti-rust agent, anti-fungal agent, quick-drying agent, and nano-oxide, mix for 80-100 minutes, and discharge to obtain the flame retardant.

[0044] A third aspect of the present invention provides a treatment process for protecting wood with a halogen-free multi-effect wood flame retardant prepared by the present invention, comprising the following steps:

[0045] (1), dry the wood to be treated to make its moisture content ≤ 10%, and treat it with microwave for 20-30 minutes;

[0046] (2), a kind of halogen-free multi-effect wood flame retardant prepared by the present invention and organic solvent are 1: 10~1: 50 ...

Embodiment 1

[0052] Example 1 provides a halogen-free multi-effect wood flame retardant, its preparation raw materials, by weight, include 85 parts of flame retardant components, 2 parts of anti-moisture agent, 2 parts of anti-rust agent, 2 parts of anti-fungal agent , 1.5 parts of quick-drying agent, 3 parts of nano-oxide.

[0053] The flame retardant component is a mixture of ammonium polyphosphate, borax and melamine, and the weight ratio is 10:2:1.

[0054] The ammonium polyphosphate II is type II ammonium polyphosphate modified by γ-aminopropyltriethoxysilane with a degree of polymerization not less than 1000 (purchased from Shandong Changsheng Flame Retardant New Material Co., Ltd., model CS FR APP 231 ), the modification method is as follows:

[0055] S1. Put γ-aminopropyltriethoxysilane (purchased from Hangzhou Jessica Chemical Co., Ltd.), ethanol and distilled water into a three-necked flask at a volume ratio of 2:10:1, and carry out at 45°C. After reacting in a water bath for 1...

Embodiment 2

[0069] Similar to Example 1, a halogen-free multi-effect wood flame retardant and its preparation method are provided, but in the preparation raw materials, by weight, it includes 70 parts of flame retardant components and 2 parts of anti-moisture agent , 2 parts of antirust agent, 2 parts of antifungal agent, 1.5 parts of quick drying agent, 3 parts of nano oxide.

Abstract

The invention discloses a halogen-free multi-effect wood flame retardant and a preparation method thereof. The halogen-free multi-effect wood flame retardant comprises the following preparation raw materials in parts by weight: 70-99 parts of a flame retardant component, 1-3 parts of a moisture resistant agent, 1-3 parts of an anti-rust agent, 1-3 parts of a mildew preventive, 1-2 parts of a quickdrying agent and 1-5 parts of a nano oxide. The flame retardant provided by the invention is low in cost, halogen-free and more environment-friendly, and the flame-retardant wood prepared by the invention has excellent flame retardancy, excellent mildew resistance, excellent rust resistance and excellent quick drying capacity.

Description

technical field [0001] The invention belongs to the field of wood flame retardants, in particular to a halogen-free multi-effect wood flame retardant and a preparation method thereof. Background technique [0002] Wood has the advantages of high strength-to-weight ratio, rich and beautiful texture and tone, excellent environmental characteristics and easy processing. It is widely used in furniture, interior decoration and construction. Wood is a flammable biomass material, and it must be flame-retardantly treated to meet the flame-retardant level of materials for public place decoration required by mandatory national standards. [0003] At present, the flame retardants used for wood on the market can be roughly divided into organic and inorganic according to their categories. Conventional flame retardants with a single flame retardant effect often cannot meet the needs. Organic flame retardants have stable molecular group structure, low moisture regain, and migration resist...
