Abstract

The invention provides a composite material for interior wall thermal insulation and crack withstanding used for fencing construction of buildings, which comprises thermal insulation putty and elastic putty. The invention also provides the construction method of the thermal insulation composite coating.

Description

technical field [0001] The invention relates to building materials, in particular to a composite coating which is effectively combined with two kinds of materials and is suitable for meeting the thermal insulation requirements of building envelopes and has the function of thermal insulation and anti-cracking. Background technique [0002] With the economic development of society, energy-saving buildings and related materials are becoming more and more popular. Therefore, the thermal insulation problem of buildings has attracted people's attention day by day. However, some insulation materials currently on the market generally have the following problems. For example, there is a contradiction between the strength and thermal conductivity of the insulation material. When the strength meets the requirements, the thermal conductivity is high; when the thermal conductivity meets the requirements, the strength is low. Or, tortoise cracks generally appear on the surface of the wal...
