Problems solved by technology

Most of the flame retardants for wood and bamboo currently on the market are relatively single in performance, and some wood flame retardants are highly acidic and easy to cause corrosion to other objects, such as condensed ammonium cyanurate wood flame retardants, which are corrosive to metal objects Strong, but subject to consumer complaints
On the other hand, the current protective treatment of wood is mainly realized through multiple treatment processes of various chemicals. Some wood flame retardants will be accompanied by dense smoke when burning, polluting the environment and human health; some wood flame retardants There are serious problems of migration and precipitation, easy to absorb moisture, and some even affect the mechanical properties of wood, etc.; Air pollution caused by indoor environment, such as formaldehyde, TVOC, etc., as well as germs, viruses, etc. brought to the indoor environment due to frequent movement of people and health reasons
[0003] CN108262828A announced the patented technology of "a kind of wood flame retardant and its application". What is claimed is the preparation method of flame retardant for flame retardant plywood, mainly using inorganic salts. Although the oxygen index is greater than 37%, the plywood The fire protection level can only meet the requirements of the national standard C level, and cannot meet the requirements of the flame retardant level B1
[0004] CN109203154A announced the patented technology of "an environmentally friendly wood flame retardant", aiming at the problem that the commonly used flame retardants will produce toxic smoke when they encounter fire, and the flame retardant effect is not good

preparation example Construction

[0040] see figure 1 , the present invention provides a technical solution: a wood and bamboo flame retardant and a preparation method thereof,

[0041] Relevant chemical mechanism of the present invention is:

[0042] (1) Benzomelamine is rich in primary amines. By utilizing the char formation and thermal stability of the benzomelamine structure and the characteristics of nitrogen-phosphorus conjugate synergistic flame retardancy, better char formation rate and flame retardancy can be obtained. The flame retardant, the material containing the flame retardant is more likely to form a dense carbon layer during combustion, thereby isolating the contact between oxygen and the internal material to achieve the flame retardant effect.

[0043] (2) Nitrogen-phosphorus-boron conjugated synergistic flame retardant, the steric hindrance in the structure of the flame retardant is large, which is conducive to improving the flame retardant effect; in addition, benzomelamine also has the ef...

Embodiment 1

[0052] Provided is a multifunctional wood and bamboo flame retardant and a preparation method thereof, comprising the following components in parts by weight: 35 parts of a main agent, 5 parts of a smoke suppressant, 6 parts of an antibacterial and aldehyde removal agent, and a synergistic effect of flame retardant and aldehyde removal 15 parts of agent, 8 parts of char-forming accelerator, and 90 parts of deionized water are mixed.

[0053] The main agent, smoke suppressant, antibacterial formaldehyde removal agent, flame retardant formaldehyde removal synergist, and char formation accelerator are prepared by the following methods:

[0054] 1. Main agent of flame retardant: under the protection of nitrogen, add appropriate amount of benzomelamine and deionized water into the reaction kettle with stirring device, raise the temperature to 90°C and stir to obtain a completely dissolved benzomelamine solution. The molar ratio of benzomelamine to deionized water is 1:25. Then dro...

Embodiment 2

[0060] Provided is a multifunctional wood and bamboo flame retardant and a preparation method thereof, comprising the following components in parts by weight: 40 parts of a main agent, 8 parts of a smoke suppressant, 4 parts of an antibacterial and aldehyde removal agent, and a synergistic effect of flame retardant and aldehyde removal 20 parts of agent, 5 parts of char-forming accelerator, and 100 parts of deionized water are mixed.

[0061] The main agent, smoke suppressant, antibacterial formaldehyde removal agent, flame retardant formaldehyde removal synergist, and char formation accelerator are prepared by the following methods:

Abstract

The invention is applicable to the technical field of flame retardants, and provides a wood and bamboo flame retardant and a preparation method thereof.The wood and bamboo flame retardant has the functions of flame retardance, sterilization, indoor harmful gas purification and the like, and contains phosphorus, nitrogen, silicon, boron, zinc, calcium, magnesium and other elements with the flame retardant effect, and nano titanium dioxide with the indoor air purification function and other substances. The multifunctional flame retardant has the advantages of flame retardance, sterilization and purification of indoor harmful gases such as formaldehyde and TVOC, is small in addition amount, can reduce the influence on the physical and mechanical properties of wood and bamboo to the greatest extent and improve the additional value of the wood and bamboo, and also has the advantages of no halogen, low smoke, low toxicity, molten drop prevention, no corrosive gas and the like. The oxygen index of wood and bamboo treated by the flame retardant is greater than or equal to 36%, the smoke density is less than or equal to 22%, the sterilization rate on staphylococcus aureus is greater than or equal to 90%, the sterilization rate on escherichia coli is greater than or equal to 92%, the formaldehyde removal rate is greater than or equal to 85%, and the TVOC removal rate is greater than or equal to 81%; the preparation method provided by the invention is simple, low in cost, easily available in raw materials and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of flame retardants, in particular to a wood and bamboo flame retardant and a preparation method thereof. Background technique [0002] With the continuous development of my country's economy, the process of urbanization continues to advance, and the trend of urban population densification is increasing. Residential and public buildings are also developing towards high-rise, three-dimensional floors and diversified functions. A large number of building materials, especially wooden decorative materials, are widely used, and the possibility of causing fire is increasing. As one of the main civil engineering disasters in urban buildings, fire seriously threatens the safety of people's lives and properties. In recent years, domestic residential and public buildings, especially high-rise, super high-rise, and long-span structures, have experienced frequent fire accidents, causing a large number of casualties and...
