Self-cleaning energy-saving coating with function of purifying air and preparation method and application of self-cleaning energy-saving coating

Abstract

The invention provides a self-cleaning energy-saving coating with a function of purifying the air. The self-cleaning energy-saving coating is prepared from the following raw materials of: in parts byweight, 10.0-20.0 parts of deionized water, 0.1-0.2 part of an antiseptic, 0.3-0.5 part of a dispersing agent, 1.3-2.0 parts of propylene glycol, 0.3-0.5 part of an anti-settling agent, 10.0-15.0 parts of photocatalytic titanium dioxide, 10.0-20.0 parts of rutile titanium dioxide, 10.0-15.0 parts of calcium carbonate, 5.0-10.0 parts of talc powder, 30.0-45.0 parts of acrylic acid emulsion, 1.0-1.5parts of a film-forming assistant, 0.2-0.6 part of a thickener, 0.2-0.4 part of an antifoaming agent and 0.2-0.5 part of a leveling agent. The invention also relates to a preparation method and application of the self-cleaning energy-saving coating. The self-cleaning energy-saving coating can be applied to coatings of interior walls and exterior walls, has the functions of air purification, selfcleaning and energy saving at the same time, and the product has strong adhesion, good durability and a simple preparation process.

Description

technical field [0001] The invention belongs to the field of materials, in particular to the field of coatings, and mainly relates to a self-cleaning energy-saving coating with air purification function and its preparation method and application, especially suitable for use as a building interior wall or exterior wall coating. Background technique [0002] In the past two decades, due to changes in life and work patterns, modern people spend more and more time indoors, and many people spend almost 90% of their time indoors. However, with the increasing incidence of respiratory diseases, leukemia, cancer and other diseases, people's attention and requirements for indoor air quality are also increasing. People have found that due to the widespread use of new building materials, especially chemically synthesized building materials, high-end furniture and household appliances have entered homes and offices one after another. Indispensable supplies lead to the continuous increas...

AI Technical Summary

Problems solved by technology

Although traditional hydrophobic self-cleaning coatings can effectively reduce the adhesion of dust etc., as Chinese patent application CN106280822A discloses a kind of self-cleaning exterior wall coating, by pure acrylic emulsion, polyorganosiloxane, organosilicon defoamer, mica Powder, calcium carbonate, etc. are stirred, dispersed and ground, and then added with cellulose for reinforcement. Although it can reduce dust adhesion, it cannot solve the problem of oil pollution on the building surface, especially in areas with serious vehicle exhaust and factory exhaust emissions, so it cannot provide long-term protection. purpose of building surfaces

Chinese patent application CN107828288A discloses a formaldehyde-resistant interior wall water paint, which is obtained by stirring acrylic acid emulsion, MCC modified calcium carbonate, formaldehyde-resistant powder, film-forming aids, etc., and solves the problem of formaldehyde-resistant latex paint in the prior art. There are problems such as high gloss, poor hiding power, poor stain resistance of the paint film, and poor persistence of formaldehyde in the decomposition chamber. It provides an effective anti-formaldehyde, and has excellent physical properties such as gloss, hiding power, and stain resistance of the paint film. formaldehyde-resistant interior wall paint

However, it is suitable for indoor decoration. When it is used for outdoor building decoration, it still cannot solve the problem of oil pollution on the building surface, and cannot solve the problem of powdering, cracking and peeling of the external coating, and cannot provide long-term protection. purpose of building surfaces
