Abstract

The invention relates to biodegradable odorless emulsion paint and a preparation method thereof. The odorless emulsion paint comprises the following components in parts by weight: 100 to 400 parts of biodegradable water-borne resin with a core-shell structure, 5 to 100 parts of nano-anatase titanium dioxide, and 5 to 15 parts of nano-anionic adjuvant. The biodegradable odorless emulsion paint can be applied to a wood material, the paint film has the characteristics of light smell, low VOC (volatile organic compounds), good covering performance, excellent adhesive force, scrub resistance and the like, and the old paint film can be biodegraded; and the emulsion paint has the advantages of low cost, good construction property, excellent environment-friendly performance, and is a product which perfectly integrates decoration, function and environmental friendliness.

Description

technical field [0001] The invention relates to an odor-cleaning paint, in particular to a biodegradable odor-cleaning latex paint and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the pursuit of individuality in home decoration is becoming more and more. Every few years, the interior home is redecorated by DIY to change the environment and mood. It is a simple and easy choice to paint the wall again. When repainting, the original paint film is often shoveled off. Because the shoveled paint film is often acrylic as a film-forming substance, it does not have Biodegradable, will keep polluting the environment for a long time. Although biodegradation technology has many applications in people's daily life, such as disposable tableware, shopping bags, etc., it is mainly plastic products, and plastics are modified by easily biodegradable starch, such as Chinese patent application CN200510090456. 2 (publication num...
