Building biological coating

Abstract

The invention discloses a building biological coating, which is characterized by including the following substances by weight: 14-19 parts of high density polyethylene HDPE, 9-14 parts of conch shell powder, 3-6 parts of biao clam shell powder, 2-3 parts of razor clam shell powder, 2-8 parts of ethylene-acrylate, 3-5 parts of high density polyethylene, 4-6 parts of talcum powder, 6-7 parts of liquid paraffin, 16-19 parts of platanus acerifolia sawdust, 3-9 parts of Syzygium jambos sawdust, 2-9 parts of Davidia involucrata sawdust, 6-9 parts of kapok sawdust, 1-3 parts of a film-forming assistant, 3-8 parts of stearic acid, 15-20 parts of isocyanate, 21-26 parts of urea formaldehyde resin, and 3-7 parts of azodicarbonamide. The building biological coating provided by the invention has the characteristics of small coefficient of thermal conductivity and large bearing strength.

Description

technical field [0001] The invention relates to a kind of architectural biological coating. Background technique [0002] At present, countries around the world are paying more and more attention to protecting the environment, and have developed many recycling technologies to apply industrial waste to construction, which means environmental protection, energy saving, and economic benefits, as well as enriching the building material market. Waste polystyrene foam (CEPS) has stable chemical properties and is not easy to corrode, which has caused great pollution to the environment. At the same time, it is a lightweight material with good thermal insulation properties. The lightweight aggregate concrete made of it as the lightweight aggregate of concrete has low density, low thermal conductivity, sound insulation, and low cost. It has been widely used abroad, especially in the United States and Canada. In addition to building villas and commercial buildings, the use of EPS lig...

Problems solved by technology

In China, this aspect started relatively late. Although there is some research on EPS lightweight aggregate concrete, they are all in the research and exploration stage, have not been popularized and applied, and there is no clear reference to regulations.
