Abstract

The invention discloses waste polystyrene foamed plastic modified coating which comprises the following ingredients in parts by weight: 100-150 parts of fluorosilicon resin, 50-60 parts of modified waste polystyrene foamed plastics, 50-60 parts of anion powder, 30-40 parts of light calcium carbonate, 30-40 parts of modified CNTs (carbon nano tubes), 30-40 parts of nano-silver, 30-40 parts of calcium hydroxide, 20-30 parts of titanium dioxide, 15-30 parts of coal ash, 15-25 parts of nano-SiO2, 3-5 parts of a surfactant, 1-2 parts of a silane coupling agent and 1-2 parts of a flatting agent. Dueto the application of the modified waste polystyrene foamed plastics in the coating, so that on one hand, the recycling of resources is achieved; on the other hand, the characteristics of the modified waste polystyrene foamed plastics of being hard in texture and good in transmission of light can be utilized, and the flexibility of the plastics is enhanced after the plastics are modified.

Description

technical field [0001] The invention relates to the technical field of latex paint for interior walls, in particular to a preparation of waste polystyrene foam modified paint and a preparation method thereof. Background technique [0002] Interior wall latex paint is a kind of paint with polymer emulsion as film former, and it is a kind of water-based paint formulated with synthetic resin emulsion as raw material by adding pigments, fillers and various additives. The main function of interior wall latex paint is to decorate and protect the building surface, so that the interior surface of the building is neat and beautiful, so as to achieve the purpose of beautifying the interior of the building, and at the same time, it can protect the interior wall of the building and prolong its service life. [0003] Polystyrene foam (PSF) has the characteristics of heat insulation, sound insulation, shockproof, waterproof, acid and alkali resistance, and has the advantages of light weig...
