Problems solved by technology

However, xylene can cause loss of appetite, nausea, vomiting and diarrhea, and sometimes cause liver and kidney damage and allergic asthma
[0004] At present, it has been reported in the literature that special paint additives are used to eliminate formaldehyde gas, such as Chinese patent 201210509400.6. In this patent, some precious metals such as zirconia and zirconium phosphate are added to paint additives. Although formaldehyde gas can be effectively absorbed, the cost is relatively high.
Chinese patent 201210457853.9 discloses a coating prepared from the peel extract of citrus plants to remove ammonia and formaldehyde gas in the air, but does not show the removal effect on toluene
However, there is no report about the effect of seaweed extract on decomposing macromolecular groups, sterilizing, and removing harmful substances, such as formaldehyde.

Abstract

The invention provides a preparation method of a building material additive. The method takes use of algae plants as raw materials. Extraction efficiency of algae active substances can be obviously increased by acid-base extraction, enzymolysis treatment, microwave treatment and addition of a corrosion-resistant agent; the building material additive has the functions of decomposing macromolecular groups and removing harmful substances by modifying the active substances via flora fermentation; and the building material additive is suitable for use in the field of building materials to improve air environment by adding the corrosion-resistant agent.

Description

technical field [0001] The invention relates to a preparation method of a building material additive, in particular to a biological extraction method of functional active substances of seaweed plants, which uses seaweed plants as raw materials to prepare building material additives, and is used for degrading toxic and harmful gases in the air, killing air bacteria. Background technique [0002] Surveys in recent years have confirmed that many families have caused indoor pollution due to decoration. There are three main sources of pollution in the home. One is interior decoration materials. Such as particleboard, fiberboard, composite flooring, plywood, paint coatings, etc., contain more than 10 kinds of volatile harmful substances such as formaldehyde, benzene, xylene, and styrene. The second is building materials. For example, granite, marble and some glazed tiles can produce radioactive substances, such as radium, thorium, potassium, radon, etc. Long-term absorption of...
