Abstract

The invention discloses a preparation method of fireproof flame-retardant wood; hydrotalcite is acidified, and ball milling is carried out on the acidified hydrotalcite and graphite to form graphene-loaded modified hydrotalcite, and thus the specific surface area of hydrotalcite is increased; the modified hydrotalcite and nano-silica are added in the process of preparing titanium dioxide by usingtetrabutyl titanate as a precursor to form a compound, and the tetrabutyl titanate grows in the compound in situ during calcination, so that the components are uniformly dispersed so as to easily improve the loading effect, and the prepared flame retardant has the more excellent flame retardant effect.

Description

technical field [0001] The invention relates to the technical field of wood treatment, in particular to a method for preparing fire-resistant and flame-retardant wood. Background technique [0002] With the rapid development of the economy, people's demand for various building materials is increasing. As one of the four major building materials, wood is the only renewable green and environmentally friendly material. And because of the excellent natural characteristics of wood, it is deeply favored by people. However, wood products are flammable and are the source and propagation medium of many fires. It not only brings potential danger to people's daily life, but also limits the application of wood in many fields. Therefore, it is necessary to carry out flame-retardant treatment on flammable wood in order to improve and enhance some of its material properties, so that it can be fully, rationally and efficiently utilized, which is to meet the requirements of economic devel...
