Problems solved by technology

At present, the current status of this material is that it has good water resistance and easy sanding in construction.
The formula mainly includes inorganic fillers and binders. At present, there are mainly the following types: ①When water-soluble cellulose or starch is used as the binder, it is easy to polish after coating, but due to the strong water absorption of the material, the resistance Poor water quality, water can easily enter the coating through capillary action, causing the coating to swell and loosen, causing the coating and the composite coating composed of the bottom or middle layer to deform, foam or even fall off, such as an environmentally friendly coating disclosed in Chinese patent 01138776.9 High-strength water-resistant putty powder and its production process just have the above-mentioned problems; 2. When cement is used as the main body of binder and filler, the coating has strong alkalinity, which destroys the color stability of the pigment in the composite coating, and is not easy to be used in construction. Fine grinding and leveling treatment; ③Using water-based latex or water-soluble polymers as adhesives, although the water resistance is improved, it cannot block the capillary water penetration, and it is difficult to polish and the cost is high. For on April 9th, 2003, publication number is that CN1408794A discloses a kind of plastering paint waterproof putty and just exists this deficiency

Abstract

A multifunctional hydrophobic air-permeable aquatic porous material in the form of paste with high water resistance for building, furniture, etc contains water, cellulose sol, aquatic disperser, high-polymer emulsion and hydrophobic inorganic filler.

Description

technical field [0001] The present invention relates to a porous material, as well as its manufacturing method and application, more specifically to a water-based multifunctional hydrophobic and breathable porous material, its manufacturing method and its application, belonging to building waterproofing, thermal insulation materials and building coatings technology field. Background technique [0002] Traditional water-based air-permeable porous materials are generally composed of inorganic materials such as hydraulic Portland cement, gypsum or air-hardened slaked lime, and are also formulated with water-based organic polymer binders and inorganic filler materials (stone powder, etc.). At present, it has been widely used in construction materials, such as plastering mortar, filling putty for building surface coating, wood putty and other fields. At present, the current situation of this material is that it can not achieve both good water resistance and easy sanding in const...
