Abstract

The invention discloses a thermal insulation building exterior wall panel, comprising a base layer, a bonding layer, a thermal insulation layer, a plastering mortar layer, a fireproof layer, a waterproof layer, a latex layer, a decorative coating and a wear-resistant layer sequentially arranged from the inside to the outside; The raw materials of the fireproof layer include by weight: 115-118 parts of modified phenolic resin, 18-21 parts of urea-formaldehyde resin, 15-18 parts of polyvinyl butyral, 20-23 parts of acrylate rubber, 0.9 parts of silane coupling agent ~1.2 parts, nylon fiber 17-20 parts, soybean fiber 12-15 parts, bentonite 21-24 parts, calcined kaolin 25-28 parts, foaming agent 17-20 parts, foaming aid 3-6 parts, microcapsules 16-19 parts of red phosphorus, 2-3 parts of antioxidant. The preparation method of the modified phenolic resin is as follows: after reacting hydroquinone and diphenyl chlorophosphate, lauraldehyde is added for the reaction to obtain the second material; and the second material is reacted with boric acid to obtain the modified phenolic resin.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a thermal insulation 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. At present, building exterior wall panels often have good thermal insulation effect, but poor fireproof performance and low bonding strength, which are difficult to meet the current needs of building exterior wall panels. Contents of the invention [0003] Based on t...
