Problems solved by technology

[0007] However, the coating system synthetic resin composition disclosed in the above-mentioned documents has many performances represented by printing performance which are worse than PVC wallpaper. Cloth), will make the performance worse, so that it can not be used, there are problems of complicated preparation process and reduced economic benefits
And when using the wallpaper made of wood flour described in the above documents, there is almost no foamability, and there is a disadvantage that it cannot be used as a foam wallpaper.

Embodiment

[0049] With 35% by weight of EVA50% aqueous solution as binding agent; 20% by weight of calcium carbonate as inorganic filler; 10% by weight of modified starch as organic filler, described modified starch is to adopt cornflour and Octenyl Succinic Anhydride (Octenyl Succinic Anhydride; OSA) reaction, and then with Al 3+ Carry out secondary reaction, thus the method for removing the hydrophilicity of starch is prepared; 8% by weight of bisphenol epoxy resin emulsion as plasticizer, described bisphenol epoxy resin emulsion is 70% aqueous solution, ring Oxygen equivalent of 300; 5% by weight of glycerin as a wetting agent; 4% by weight of isobutane as a foaming agent in capsule form; 5% by weight of titanium oxide as a colorant; 12% by weight of diluent Water; 0.5% by weight of silicon defoamer as other additives; and 0.5% by weight of urethane associative tackifier etc. were put into a mixer and stirred at normal temperature to prepare an environmentally friendly coating composi...

Abstract

The invention relates to an environment-friendly coating composition for a building interior material. The environment-friendly coating composition comprises an adhesive, a filler, a plasticizer, water and other additives. The environment-friendly coating composition is characterized in that, polyester is used as the adhesive, modified starch is used as an organic filler, and an epoxy resin emulsion is used as the plasticizer. The environment-friendly coating composition is advantageous in that, biodegradable polyester is used as the adhesive, thereby improving biodegradation rate, the epoxy resin emulsion is used as the plasticizer, thereby preventing generation of volatile organic compound, and use of an organic solvent, since the hyrophobic modified starch is used as the organic filler, reducing the condition of tacky coated composition and improving drying speed, thereby improving operation efficiency, and the water is used as the solvent, and therefore a water-based paint composition is provided.

Description

technical field [0001] The present invention relates to an environment-friendly coating composition for building interior decoration materials, more particularly, relates to a kind of environment-friendly coating for building interior decoration materials containing binder, filler, plasticizer, water and other additives Compositions, especially, the environmentally friendly coating composition uses biodegradable polyester as a binder, hydrophobic modified starch as an organic filler, and epoxy resin emulsion as a plasticizer. Background technique [0002] Recently, with the upsurge of health concerns, there has been an increased demand for materials used for building interiors to be environmentally friendly and harmless to the human body. Interior materials used in construction are, for example, wallpaper, vertical shutters, blinds, curtains, plasterboard, moulding, MDF, OSB, partitions, panels, ceilings, lamp shades, staircase materials, solid wood, etc. [0003] In order ...
