Abstract
The invention provides putty powder and high elastic fiber putty for wall crack resistance, and relates to the field of building materials. The putty powder comprises 8 to 10 parts by weight of water-soluble flexible putty rubber powder; 1 to 2 parts by weight of polypropylene short fiber; 350 to 450 parts by weight of cement; and 540 to 700 parts by weight of calcium powder. The high elastic fiber putty comprises liquid slurry and the putty powder; the liquid slurry comprises 70 to 130 parts of an acrylic emulsion; 70 to 130 parts of aqueous polyurethane resin; and 4 to 6 parts of an auxiliary agent. The putty powder and the high elastic fiber putty have high flexibility, high adhesion, strong elongation and high film forming property, and can effectively solve the risk of wall cracking.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a putty powder and high-elastic fiber putty used for wall crack resistance. Background technique [0002] Putty (filling mud) is a kind of decorative material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. It is applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated, and to lay a good foundation for obtaining a uniform and smooth paint surface. It is generally composed of base materials, fillers, water and additives composition. [0003] At present, the putty on the market has the biological problems of insufficient extensibility and film-forming property, and cannot effectively prevent the wall from cracking. Contents of the invention [0004] The object of the present invention is to provide a kind of putty powder and high-elastic fiber put...
