Building energy conservation wallboard

Abstract

The invention discloses a building energy conservation wallboard. The building energy conservation wallboard comprises a polyurethane foamed board, and a silicon dioxide aerogel interlayer is fixed at each of two surfaces of the polyurethane foamed board. The polyurethane foamed board is fixed with the silicon dioxide aerogel interlayers at the two surfaces thereof through adhesive bonding or bolts. The building energy conservation wallboard uses polyurethane foamed board and silicon dioxide aerogel compounded material, and each of the polyurethane foamed board and silicon dioxide aerogel has a good heat insulation effect; straw is mixed in the polyurethane foamed board, and the heat insulating property is further improved; the polyurethane foamed board and straw are low in cost, and the cost of the energy conservation board can be lowered; the silicon dioxide aerogel has fire and explosion protection performance; the silicon dioxide aerogel is fixed at two sides of the polyurethane foamed board, and accordingly the fireproof performance of the energy conservation board is improved.

Description

technical field [0001] The invention relates to an energy-saving thermal insulation board, in particular to a building energy-saving wall board. 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 and disadvantages...
