A kind of indoor paint with sound absorption function and preparation method thereof
Technical field
The present invention relates to coating technology Material Field, particularly relate to a kind of indoor paint with sound absorption function and preparation method thereof.
Background technology
Paint finishing can bond very well with body material in body surface and form the material of complete and tough and tensile protective membrane, is called coating.Coating and paint are identical concepts.Paint is people's custom titles used for a long time, after introducing China, just utilizes in building trade always.The effect of coating may be summarized to be three aspects: provide protection, decoration function, specific function effect.The general composition of coating: comprise filmogen, color stuffing, solvent, auxiliary agent.
Building coating has decoration functions, defencive function and livability and improves function.Proportion shared by various function is not quite similar because application target is different.Decoration functions is the function of beautifying the appearance value improving it by buildings.Mainly comprise the design design of plane color, pattern and gloss aspect and the design design of three-dimensional pattern.But to match with the size and shape of the moulding of buildings itself and base material itself, just can fully play out.
Defencive function refers to architecture protection thing not by the impact of environment and the function of destruction.The content that different types of protected body requires defencive function is also different.As just very large in the indoor index difference with reaching required by outdoor application.Some buildingss to mildew-resistant, fire prevention, heat insulating, corrosion-resistant etc. have particular requirement.
Livability improves function mainly for indoor application, contributes to the function improving living environment exactly, as effect and classification, the antisweat etc. of sound-proofing, sound absorbing coating.
Coating act as decoration and protection, protects by the surface being coated with jewelry, prevents the erosion of the light, oxygen, chemical substance, solvent etc. from the external world, improve the work-ing life of coated thing; Paint finishing material surface, changes its color, decorative pattern, gloss, texture etc., improves the aesthetic value of object.
Organosilicon crylic acid latex is that the organosilane monomer containing unsaturated link(age) and acrylic monomer are added suitable auxiliary agent, the emulsion be polymerized by the coated polymerization technique of nucleocapsid.Combine organosilicon fire-resistant, weathering resistance, chemical-resistant, high tint retention, snappiness, the tack of the low not v ulnerability of hydrophobic, surface energy and acrylic resin.A kind of high durable, high water-fast, resistant to pollution environment-friendly type building emulsion and coating.
The invention provides a kind of indoor paint with sound absorption function, there is excellent illumination aging resisting, anti-microbial property.
