Abstract

The invention discloses a fireproof building exterior wall panel, which comprises a base layer, a fireproof layer and a wear-resistant decorative layer arranged sequentially from inside to outside; wherein the raw materials of the fireproof layer include: 97-100 parts of modified phenolic resin, melamine 22-25 parts of formaldehyde resin, 9-12 parts of liquid nitrile rubber, 14-17 parts of polyphenylene ether ketone, 0.9-1.2 parts of silane coupling agent, 13-16 parts of jute fiber, 5-8 parts of potassium titanate fiber, 23-26 parts of white carbon black, 21-24 parts of montmorillonite, 15-18 parts of foaming agent, 3-6 parts of foaming aid, 24-26 parts of hydrated zinc borate, 2-3 parts of anti-aging agent. The preparation method of the modified phenolic resin is as follows: react hydroquinone with diphenyl chlorophosphate to obtain the first material; react the first material with lauryl aldehyde to obtain the second material; Ammonium molybdate is reacted to obtain modified phenolic resin.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a fireproof building exterior wall panel. Background technique [0002] At present, the total energy consumption of buildings in my country has exceeded 30% of the total primary energy consumption, ranking first in energy consumption, and the proportion of building energy consumption in my country's energy consumption is still increasing year by year. Building energy conservation has become one of the key areas of energy conservation in the whole society. First, the energy-saving and thermal insulation of building exterior walls is one of the key points of building energy-saving and consumption-reducing. However, the existing building exterior wall panels often have poor fireproof performance and low bonding strength, which are difficult to meet the current needs for building exterior wall panels. Contents of the invention [0003] Based on the technical problems in the backg...
