Problems solved by technology

[0003] Since most of the ancient buildings have the nature of cultural relics, or because of religious and ethnic customs, the principle of maintaining the original appearance must be followed for flame retardant treatment of these materials. Now there are the following problems in the flame retardant liquid of ancient buildings: First, maintain flame retardant Under the premise, it is difficult to maintain the original appearance. Second, a large amount of toxic and harmful substances are used in flame-retardant materials, and the flame-retardant effect is not ideal.

Embodiment 1

[0024] Example 1 Table 1 Flame Retardant Liquid Formula (Kg)

[0025] components

[0026] According to the weight in Table 1, add formaldehyde into the reaction kettle, adjust the pH value to 7.5 with triethanolamine, add melamine while stirring, raise the temperature to 60°C, and react for 2 hours. When the solution becomes clear and transparent, cool to room temperature and add Water, sodium lignosulfonate, water-soluble ammonium polyphosphate, and o-cresyl glycidyl ether are stirred evenly, and finally the pH value of the solution system is adjusted to 6.5 with triethanolamine, and a colorless, odorless, impurity-free, uniform transparent liquid is obtained.

Abstract

The invention provides a water-based flame retardant liquid for a historic building. The water-based flame retardant liquid comprises the following components: formaldehyde (37% water solution), melamine, sodium lignin sulfonate, water-soluble ammonium polyphosphate and o-methylphenyl glycidyl ether. The flame retardant liquid is capable of keeping the original appearance of the historic building, and is good in flame retardant effect, and few in toxic and harmful substances.

Description

technical field [0001] The invention relates to the field of fire prevention and flame retardant, in particular to a water-based flame retardant liquid for ancient buildings and a preparation method thereof. Background technique [0002] A large number of various ancient buildings left over from various dynasties in history have high spiritual value, cultural value and practical value. However, these ancient buildings are limited by historical conditions, and have been built for a long time, and most of them are wooden buildings, so there are generally a lot of safety hazards. And fire is the enemy of ancient buildings, because fires cause damage to ancient buildings every year. [0003] Since most of the ancient buildings have the nature of cultural relics, or because of religious and ethnic customs, the principle of maintaining the original appearance must be followed for flame retardant treatment of these materials. Now there are the following problems in the flame retar...
