AI Technical Summary

Problems solved by technology

Because organic flame retardants can produce toxic gases and dense smoke in a fire, the visibility of the fire site is low, causing difficulties for firefighting and rescue, and even poisoning, and the price is relatively expensive, which greatly limits the application. Among them, brominated flame retardants Agents have the possibility of producing dioxins, and should be used as little as possible

Embodiment 1

[0060] Embodiment 1, a kind of B-P-Zn-Sb-Si series density board flame retardant antifungal composition, raw material components are as follows, are mass parts:

[0061] Sodium borate (Na 2 B 4 o 7 10H 2 O): 60 kg; ammonium polyphosphate ((NH 4 PO 3 ) n ): 50 kg, zinc borate (2ZnO 3B 2 o 3 3.5H 2 O): 40 kg, antimony trioxide (Sb 2 o 3 ): 38 kg, 40% ethanol solution of organic silicon quaternary ammonium salt: 30 kg, wherein the content of organic silicon quaternary ammonium salt is 12 kg.

[0062] Preparation method, the steps are as follows:

[0063] Dry sodium borate at 60-70°C for 6 hours, then mix it with 40% ethanol solution of organosilicon quaternary ammonium salt, stir for 20 minutes to make it evenly mixed, let it stand for 12 hours, then add ammonium polyphosphate, zinc borate and Antimony trioxide, stirred for 30 minutes, that is.

Embodiment 2

[0064] Embodiment 2: application example

[0065] Utilize the density board flame retardant antimold composition of embodiment 1 to prepare flame retardant antimold density board 1A, 1B, 1C, the steps are as follows:

[0066] 200 kg of density board flame retardant and antifungal agent compositions prepared in Example 1 were respectively added to qualified fibers obtained by washing and grinding with 3100 kg, 3800 kg and 4800 kg of dry wood, and stirred for 30 min to make the fibers and flame retardant After the antifungal agent is mixed evenly, it is sent to the glue spraying system, and then it is paved, hot pressed at 200°C, cut off, and cooled to obtain three kinds of flame-retardant and anti-mold density boards 1A, 1B, and 1C. MDF production process can refer to "Pan Shuqing Zhou Yushen high-density fiberboard continuous flat pressing production line process design [J] Wood Processing Machinery 2003. (4). 1-8". This process needs to add a flame retardant and antifungal a...

Embodiment 3

[0073] Embodiment 3, B-P-Zn-Sb-Si series density board flame retardant antifungal agent composition

[0074] As described in Example 1, the difference is that the raw material components are as follows:

[0075] Sodium borate (Na 2 B 4 o 7 10H 2 O): 70 kg;

[0076] Ammonium polyphosphate ((NH 4 PO 3 ) n ): 40 kg;

[0077] Zinc borate (2ZnO·3B 2 o 3 3.5H 2 O): 34 kg;

[0078] Antimony trioxide (Sb 2 o 3 ): 40 kg;

[0079] 40% ethanol solution of organic silicon quaternary ammonium salt: 40 kg, that is, 16 kg of pure organic silicon quaternary ammonium salt.

[0080] The preparation method is the same as in Example 1.

Abstract

The invention relates to a B-P-Zn-Sb-Si series density board flame-retardant mildew-proof agent and a preparation method and application thereof. The density board flame-retardant mildew-proof agent comprises the following raw material ingredients in parts by mass: 30-80 parts of sodium borate, 30-70 parts of ammonium polyphosphate, 20-40 parts of zinc borate, 20-40 parts of diantimony trioxide and 6-20 parts of organic silicon quaternary ammonium salt. The additive amount of the B-P-Zn-Sb-Si series density board flame-retardant mildew-proof agent composition provided by the invention is 4-6%of the absolute dry wood mass of raw materials of a density board when the B-P-Zn-Sb-Si series density board flame-retardant mildew-proof agent composition is applied; and the manufactured flame-retardant mildew-proof density board has the advantages of even oxygen index for combustion which exceeds 39.0%, capability of reaching the B1-level standard for the combustibility of construction and decoration materials and according with the requirements of the fire law.

Description

technical field [0001] The invention relates to a flame-retardant and mildew-proof material for density boards, in particular to a flame-retardant and mildew-proof agent composition for density boards containing B-P-Zn-Sb-Si elements and a preparation and application method thereof, belonging to the technical field of chemical materials. Background technique [0002] With the rapid development of the national economy, people's living standards have been greatly improved, and the per capita housing area is getting larger and larger. At present, the per capita housing construction area of ​​our residents has exceeded 30 square meters per person. The unprecedented prosperity of the interior decoration industry has led to a large consumption of various materials. In 2009, my country's wood consumption reached 330 million cubic meters, becoming the second largest wood consumer in the world after the United States. my country's forest resources are scarce, and the timber is serio...
