Problems solved by technology

[0003] Existing thermal insulation exterior walls are mostly constructed on-site. Usually, mortar, benzene boards, hanging nets, thin plastering, etc. are applied on the exterior walls once. The strength is poor, so that the aging period of the outer wall is very different, which makes the thermal insulation and decoration function of the outer wall decline, and affects the service life

Abstract

The invention discloses an outer wall decorative wallboard made of heat preservation energy-saving composite materials. The outer wall decorative wallboard comprises a decorative layer, a heat insulating and preserving layer a and a heat insulating and preserving layer b. The heat insulating and preserving layer a is arranged between the decorative layer and the heat insulating and preserving layer b. The decorative layer, the heat insulating and preserving layer a and the heat insulating and preserving layer b are integrated through polymide glue in a bonding mode. The outer wall decorative wallboard made of the heat preservation energy-saving composite materials is friendly to the environment, nonpoisonous, ageing resistant, and good in toughness and energy conservation and heat preservation performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation and energy saving composite exterior wall decorative wallboard and a preparation method thereof. Background technique [0002] Building insulation is a measure to reduce the heat emitted from the building indoors to the outside, and plays an important role in creating a suitable indoor thermal environment and saving energy. Building thermal insulation mainly takes measures from the building envelope structure, and at the same time, measures to reduce the indoor heat of the building to the outside play an important role in creating a suitable indoor thermal environment and saving energy. [0003] Existing thermal insulation exterior walls are mostly constructed on-site. Usually, mortar, benzene boards, hanging nets, thin plastering, etc. are applied on the exterior walls once. The difference in strength makes the aging period of the outer wall very different...
