Abstract

The invention provides an urban greenway inorganic silicate coating which is prepared by mixing the following components in parts by weight: 27.9-30.4 parts of water, 0.3-0.5 part of ethyl hydroxyethyl cellulose, 0.6-0.8 part of a dispersing agent, 0.2-0.4 part of a wetting agent, 0.4-0.6 part of a defoaming agent, 0.4-0.6 part of a dispersion stabilizer, 6-10 parts of rutile titanium dioxide, 16-20 parts of modified composite silicate toughening powder and 4-8 parts of barium sulfate, wherein the modified composite silicate toughening powder can be subjected to bonding reaction with hydroxylfunctional groups of the nano inorganic silicon modified silicate solution, 2-4 parts of acrylic emulsion, 0.1-0.2 part of a coalescing agent, 30-32 parts of a nano inorganic silicon modified silicatesolution, 0.2-0.4 part of a thickening leveling agent and 1-3 parts of inorganic pigment color paste. The coating solves the problems of poor wear resistance, easy fading, poor water and air permeability and long construction period of the traditional organic coating in the field of urban greenway coating.

Description

technical field [0001] The invention relates to the technical field of architectural decoration functional coatings, in particular to an inorganic silicate coating for urban greenways and a preparation method thereof. Background technique [0002] The concept of "sponge city" was first proposed in the "2012 Low Carbon City and Regional Development Science and Technology Forum". Next, give priority to more use of natural power to drain water, and build a sponge city with natural accumulation, natural infiltration, and natural purification. The urban greenway is a green open space that can be entered by pedestrians and cyclists, has a good natural landscape, and mainly has leisure functions, which can fully reflect the humanistic atmosphere of the city. How to incorporate urban greenway construction into sponge city management has always been an important task. [0003] At present, the traditional process is to lay large-grain sand concrete on the road surface, and then appl...
