Fouling-resistant energy-saving environment-friendly stone-like coating material and preparation method thereof

Abstract

The invention discloses a fouling-resistant energy-saving environment-friendly stone-like coating material. The fouling-resistant energy-saving environment-friendly stone-like coating material is formed by mixing a basic material component and a powder component according to a proportion of (20 to 30):(70 to 80), wherein the basic material component is prepared from the following raw materials inparts by weight: 45.0 to 75.0 parts of synthetic resin emulsion, 2.5 to 6.5 parts of functional material, 7.0 to 21.0 parts of deionized water, 0.1 to 0.8 part of preservative, 3.0 to 5.0 parts of coalescing agent, 0.5 to 3.0 parts of antifreeze agent, 5.0 to 16.0 parts of 2.5 percent cellulose and 0 to 0.5 part of thickening agent; the powder component is prepared from different proportions of various white sand and colored sand of which the grain diameters are 10 to 180 meshes. The invention also discloses a preparation method of the fouling-resistant energy-saving environment-friendly stone-like coating material. The technical scheme is that the fouling-resistant energy-saving environment-friendly stone-like coating material is characterized by belonging to waterborne products, the VOC(Volatile Organic Compound) content is smaller than 15g/L, and the fouling-resistant energy-saving environment-friendly stone-like coating material is green and environmentally friendly; a vivid decoration effect of natural stones is obtained; excellent heat preservation and energy saving effects are obtained, and the indoor temperature can be reduced by 8 to 10 DEG C; the fouling resistance is very good and can be up to 0 grade, and the fouling resistance grade cannot be achieved by two-grade fouling resistance of a conventional stone-like coating material.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, in particular to a stone-like paint and a preparation method thereof, in particular to a pollution-resistant, energy-saving, environment-friendly stone-like paint and a preparation method thereof. Background technique [0002] In recent years, 1 billion square meters of civil buildings have been put into use (put into use) every year in my country, and the proportion of building energy consumption to the total energy consumption of the whole society has risen from 10% in the 1980s to 27.5% at present. For this reason, the state pays close attention to building energy conservation and has issued a series of relevant regulations on building energy conservation. Since the energy saving of buildings is difficult to achieve the expected indicators such as energy saving of more than 65% only by the wall materials themselves, the building exterior wall coatings with good energy sav...

Problems solved by technology

[0003] In view of this, the industry generally adopts dry-hanging insulation boards on the outer walls of buildings or scrape-coats inorganic insulation mortar and insulation putty with a designed thickness, and then coats ordinary paint to achieve decoration, insulation and energy-saving effects. This can be achieved by Not limited to Chinese patents CN101725311A (perlite fiber composite fireproof heat insulation board), CN2352333Y (composite heat insulation and heat insulation board), CN2825784Y (external wall heat insulation and heat insulation board), CN20138361Y (external wall insulation and decorative flame retardant heat insulation board) , CN102219455A (inorganic light aggregate thermal insulation board and its preparation method) and CN102417327A (integrated solidified inorganic thermal insulation board for building exterior wall and its preparation method) etc., but such decorative effects are monotonous, with drumming and falling off phenomena Frequent occurrences have brought great potential safety hazards; for this reason, people have developed heat-insulating reflective coatings with significant heat-insulating effects and are applied to exterior wall coatings, which can be obtained by not limited to Chinese patent 201410387725.0 (a A reflective heat-insulating coating), 200810200915.1 (hollow glass bead heat-reflective coating), 201410429910.1 (a water-in-water reflective heat-insulating colorful coating), which solve the above problems well; texture, poor decoration

[0004] Although not limited to invention patents 201410230086.7 (imitation stone coating) and 201410328908.5 (imitation stone coating and its preparation method), although the above-mentioned shortcomings are overcome and excellent simulation effects (that is, the decorative effect of imitation stone is extremely realistic), their pollution resistance is poor. And does not have the effect of heat preservation and energy saving

[0005] And not limited to the invention patent 201510737708.X (a kind of heat insulation and fireproof stone-like coating) has achieved a perfect combination of heat preservation, energy saving and decoration, but the flat pollution resistance determined by the properties of conventional simulated stone coatings is still its defect
