Embodiment Construction

[0014] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.

[0015] An environmentally friendly halogen-free flame retardant for wood flame retardancy, its components are proportioned by mass percentage: ammonium polyphosphate 44%, boron-containing compound 10%, silica sol 25%, aluminum chloride 6%, magnesium chloride 6% %, sodium molybdate 5%, diethanolamine 3%, pentaerythritol 1%. Wherein, the boron-containing compound is a mixture of boric acid and borax at a mass ratio of 1:1; the silicon dioxide content of the silica sol is 20-40 wt%.

[0016] Preparation method: Weigh each component according to the mass percentage content, add to a blender and mix well, and after drying, pulverizing and drying, the present invention is obtained.

[0017] The process of carrying out flame-retardant treatment of wood by using an environmentally friendly halogen-free flame retardant for wood flame-retardant o...

Abstract

The invention discloses an environment-friendly halogen-free timber flame retardant and applications thereof. The flame retardant is composed of the following components in percentage by weight: 20 to 50% of polyammonium phosphate, 5 to 10% of boron-containing compound, 10 to 40% of silica sol, 3 to 10% of aluminum chloride, 3 to 10% of magnesium chloride, 3 to 8% of sodium molybdate, 0.5 to 3% of diethanolamine, and 0.1 to 1% of pentaerythritol. Compared with the prior art, the environment-friendly halogen-free timber flame retardant has the advantages of no toxicity, low smoke and good flame retardant effect. The oxygen index of timber processed by the provided flame retardant can reach 60% or more, and the smoke density is 25% or less.

Description

technical field [0001] The invention relates to the technical field of flame retardants, in particular to an environment-friendly halogen-free flame retardant for wood flame retardant and its application. Background technique [0002] With the improvement of social living standards, the quantity and quality of construction, interior decoration, furniture, and office appliances are constantly being updated and increased. These interior decoration, furniture, office appliances and other materials are mainly made of wood. However, wood is easy to burn. Once a fire occurs, it is difficult to control the fire, which often causes huge loss of life and property. In order to reduce the fire hazard of wood, it must be treated with flame retardants to obtain flame retardant wood before use. However, the existing wood flame retardants generally have disadvantages such as poor flame retardancy, difficulty in impregnating, and affecting mechanical properties. Contents of the invention...
