Problems solved by technology

[0003] Most of the floor coatings currently used in my country still use traditional solvent paints, and a small amount is also reported to be used in water-based epoxy coatings. However, the former contains a large amount of harmful substances that will harm construction personnel and affect the environment. Shanghai and other regions have construction every year Accidents where people were poisoned and injured
As for the latter, although the toxicity of water-based epoxy has improved (water-based, but no VOC value has been announced), due to the large number of coatings, complex formulas, complicated processes and long maintenance time after coating (requiring more than a week), Therefore, it is also greatly restricted in the use of

Abstract

The invention relates to a water-based paint for terrace. The ingredient and the weight percentage of the materials formula of the paint are as follows, 34-46% organosiloxane-acrylate core-shell polymer emulsion, 1.0-2.5% dispersant, 3-8% for titanium pigment, 36-48% stuffing material, 2-5% pigment or color paste, 2-5% film forming addition agent, 0.3-0.6% defoamer proportion, 0.2-15 pH modifying agent, and the rest is water. Compared with the existing technique, the paint of the invention has the advantages that the invention is environment-friendly, energy-saving, safe and reliable, and fast-dried, maintenance time of the invention is short, the repainting work is easy, and the like.

Description

technical field [0001] The invention relates to a water-based liquid film coating suitable for floor coating, in particular to an emulsion polymer with a silicone-modified acrylic core-shell structure and silica lime as the main film-forming substance, and other additives prepared water-based coatings. Background technique [0002] With the rapid development of today's social economy, construction projects emerge in endlessly. Buildings, shopping malls, industrial parks, garages and various places abound. Floor maintenance has become an indispensable construction measure. As a floor coating, civilized, clean, safe and environmentally friendly, reliable and durable have become its performance Mainstream requirements of quality. [0003] Most of the floor coatings currently used in my country still use traditional solvent paints, and a small amount is also reported to be used in water-based epoxy coatings. However, the former contains a large amount of harmful substances tha...
