Abstract

The invention provides a dry powder mortar used for making a waterproof paint, which can solve the problem of difficult long-term immersion and poor connection during usage of the current waterproof paint. The dry powder mortar comprises the following components by ratio: 30-40% of cement, heavy calcium, 40-45% of water-rich sand, 5-7% of glue powder, an antifoaming agent, an antiseptic, a water reducer, cellulose, 10-20% of water and 1-2% of PP fiber. The dry powder mortar can be used for gradually discharging moisture in building concrete, indoor wet and mildew can be avoided, and smooth breathing of the building can be realized; the dry powder mortar has same general character with concrete and a tile glue, strong affinity is generated among the dry powder mortar, the concrete and the tile glue, and phenomena of water leakage and tile shedding can not be generated due to long-term usage; comprehensive cost is low, construction is simple, the dry powder mortar has no strictness to base requirement, so that construction can be carried out when the flattening strength of base is enough and no water is generated.

Description

technical field [0001] The invention relates to waterproof materials for construction, in particular to dry powder mortar for making waterproof coatings. Background technique [0002] Traditional waterproof coatings such as polymer cement waterproof coatings, acrylic waterproof coatings or polyurethane waterproof coatings are generally in the form of flexible films. Traditional waterproof coatings are airtight and water-permeable, so that the moisture in the concrete cannot be gradually discharged. Long-term contact with the film-forming flexible waterproof layer will cause the waterproof layer to thicken. When used in the bathroom or a humid place for a long time, the flexible film will thicken due to long-term seepage If the surface of the traditional flexible waterproof coating is smooth and cannot be tightly combined with the concrete tile adhesive, it will lead to poor bonding between the tile and the base layer, and water channeling will easily occur. In order to preve...
