Abstract

The present invention relates to a building material additive with the fanction of automatically regulating humidity, belonging to the separation field of gas or steam. Its composition contains (by weight portion) 10-70 portions of sepiolite family minerals, 2-40 portions of wood fibre, 5-40 portions of compound phosphate, 0.1-10 portions of cellulose, 2-10.5 portions of active carbon, 0-3 portions of inorganic antibacterial agent and 0-3 portions of mildew-resisting agent, and its preparation method includes the following steps: pickling sepiolite family minerals, activating and mixing all the components, making slurry, forming, roasting and breaking, etc. Said invented additive can be added into various building materials, and can effectively improve indoor environment air quality.

Description

technical field [0001] The invention belongs to the field of gas or steam separation, and in particular relates to a humidity-regulating functional material for adjusting indoor humidity by absorbing moisture or releasing moisture. Background technique [0002] As we all know, the relative humidity of the most suitable environment for human survival is between 40% and 70%. [0003] When the relative humidity is lower than 40%, many items such as paint, paint, bamboo, furniture, etc. will delaminate, deform and even crack, and human skin will lose moisture and become dry, and due to dry eyes, nose and oral mucosa, Reduce the resistance of people's respiratory system, people will feel uncomfortable or even get sick; at the same time, the ambient humidity is too low, causing the influenza virus and highly pathogenic Gram-positive bacteria to multiply faster, and spread with dust, which is easy to cause disease and the prevalence of infectious diseases. [0004] And when the r...
