Abstract

The invention discloses an external wall panel with excellent fireproof performance. The external wall panel comprises a base layer, a heat-insulation fireproof layer, a finishing mortar layer, a waterproof layer, a decorative coating and a wear-resistant layer which are arranged sequentially from inside to outside, wherein the heat-insulation fireproof layer is prepared from the raw materials in parts by weight: 27-30 parts of hydroquinone, 11-14 parts of hexachlorocyclotriphosphazene, 18-22 parts of poly (1,6-hexamethylene adipate) diol, 65-70 parts of diphenylmethane diisocyanate, 50-60 parts of ethylene glycol, 0.8-1.2 parts of pentaerythritol, 0.3-0.6 part of dibutyl tin dilaurate, 25-35 parts of foaming agent, 9-12 parts of foaming auxiliaries, 19-22 parts of expanded perlite, 13-16 parts of bentonite, 6-9 parts of diatomite, 5-8 parts of glass fibers, 12-15 parts of cotton fibers, 16-19 parts of magnesium hydroxide and 2-3 parts of anti-aging agent. According to the external wall panel, the high-temperature resistance and fireproof performance are excellent, the water resistance is excellent, the hardness is high, and the compression resistance is good.

Description

technical field [0001] The invention relates to the technical field of wallboards, in particular to an exterior wallboard with excellent fireproof performance. 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. There are mainly three energy-saving methods of the existing building envelope structure, three methods of external wall internal insulation, external wall internal insulation and sandwich insulation. These three insulation methods have their own advantages a...
