Waterproof heat insulation dry powder coating

Abstract

The invention discloses a waterproof heat insulation dry powder coating, and belongs to the field of building materials. The coating contains the following raw materials in part by weight: 42 go 55 parts of white cement, 38 to 45 parts of quartz powder, 5 to 10 parts of re-dispersible latex power, 3 to 6 parts of silicon ash, 4 to 8 parts of hollow fiber, 0.3 to 0.6 part of water reducing agent, 0.2 to 0.5 part of cellulose ether, 0.5 to 1 part of coupling agent and 3 to 5 parts of talcpowder. The dry powder coating is easy to pack, store and transport, and has long storage life and good waterproof performance, heat insulation and cracking resistance; the white cement, the quartz powder, the re-dispersible latex power and the silicon ash are used together to generate a strong bonding force; the hollow fiber not only can improve the strength of a coating and prevent cracks, but also can reflect light and heat and reduce heat conducting speed; and the talcpowder and the silicon ash havegood radiation cooling effect, and are cooperated with the hollow fiber so that the heat insulation performance of the hollow fiber can be greatly improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a dry powder waterproof and thermal insulation coating. Background technique [0002] With the development of social economy, the increasingly prominent energy issues make energy saving the focus of the whole society. In my country, building energy consumption accounts for about 1 / 3 of the national energy consumption, and it is a veritable "big household" of energy consumption. If waterproof and thermal insulation coatings can be used in the construction of exterior walls and roofs, it will undoubtedly be an important way to reduce building energy consumption. However, most of the domestic waterproof coatings used for roofs and exterior walls have single functions and poor comprehensive performance, which cannot meet the requirements of building energy conservation. In fact, exterior wall paint is related to the face of a building and is used in a large amount. It ...
