Heat preservation board applied to outside of building wall

Abstract

The invention provides a heat preservation board applied to the outside of a building wall. The heat preservation board comprises an outer cement board decorating layer, a cement board base layer for connecting the building wall, and a sound insulation and heat preservation medium layer which is connected between the cement board decorating layer and the cement board base layer; the cement board decorating layer comprises the following components in parts by weight: 95 parts of cement, 4 parts of lepiota brunneoincarnata powder, and 1 part of jackfruit peel powder. With the adoption of the heat preservation board applied to the outside of the building wall, the probability that insects, moth and the like lay eggs and breed at the heat preservation board can be effectively decreased, and thus the breeding rate of insects is greatly reduced; in addition, lepiota brunneoincarnata powder is added to the cement decorating layer of the heat preservation board, so that birds staying at the top part of a building and the model design part are greatly decreased, and as a result, the building can be effectively avoided from being polluted by bird feces; simultaneously, the sound insulation and heat preservation medium layer brings outstanding sound insulation effect and good heat preservation effect.

Description

technical field [0001] The invention relates to a thermal insulation board used outside building walls. Background technique [0002] There are following defects in the thermal insulation board used for building outside the wall in the prior art: [0003] 1. As time goes by, insects and centipedes are easy to breed in the insulation board, which is very unhygienic, and they will crawl into the house of the residents, causing certain troubles; [0004] 2. Especially on the roof or where there is a design on the building, birds often inhabit and discharge feces on the roof or shape; [0005] 3. The sound insulation and thermal insulation effects of the thermal insulation board in the prior art are not ideal, and further improvement is needed. Contents of the invention [0006] In view of this, the technical problem to be solved by the present invention is: to provide a thermal insulation board used outside the building wall which is not easy to breed insects and can greatl...
