Waterproof early-strength decoration mortar and preparation method thereof

Abstract

The invention discloses waterproof early-strength decoration mortar. The defect that traditional mortar cannot have both advantages of bright color and excellent waterproof early-strength effect at the same time is solved. According to main points of the technical scheme, the waterproof early-strength decoration mortar comprises the following ingredients (by weight): 20-30 parts of white sulphate aluminium cement, 20-30 parts of white portland cement, 10-15 parts of a silicon-acrylate emulsion, 5-8 parts of a permeable crystalline material, 30-40 parts of mineral sand, 5-20 parts of PP fiber, 10-20 parts of calcium ion powder, 3-6 parts of dispersible latex powder, 1-5 parts of cellulose ether, 1-5 parts of a water reducer and 1-5 parts of an antioxidant. The prepared mortar has excellent waterproofness and high strength, and has a decoration effect. According to the invention, defects of decoration mortar in the market, such as poor waterproofness and low early-strength, are compensated; and the waterproof early-strength decoration mortar with excellent properties is prepared.

Description

technical field [0001] The invention relates to building materials, in particular to a waterproof early-strength decorative mortar and a preparation method thereof. Background technique [0002] Decorative mortar has been widely used in the decoration of interior and exterior walls of buildings instead of paint and ceramic tiles in developed countries. Generally, it is made of polymer materials as the main additive, together with high-quality mineral aggregates, fillers and natural mineral pigments. It is coated with a thickness of about 1.5-2.5mm on the wall, which has excellent texture and three-dimensional decoration. Effect. [0003] At present, the Chinese patent with the authorized notification number CN101857408B among the existing patents discloses a kind of interior wall decorative mortar and its construction method, which is composed of ordinary Portland cement, slaked lime, light aggregate, negative ion additives, heavy aggregate and composite additives.

Problems solved by technology

[0003] At present, the Chinese patent with the authorized notification number CN101857408B among the existing patents discloses a kind of interior wall decorative mortar and its construction method, which is composed of ordinary Portland cement, slaked lime, light aggregate, negative ion additives, heavy aggregate and composite additives. The decorative mortar has outstanding three-dimensional texture and good decorative effect, but this type of decorative mortar generally does not have the performance of waterproof, light weight and high strength; the Chinese patent application publication number CN103224363A discloses a flexible anti-crack Protective mortar and its preparation method are made by mixing ordinary Portland cement, quartz sand, slaked lime, anti-cracking fiber, renewable dispersed latex powder, cellulose ether, plastic expansion agent, and water-repellent agent. This type of ordinary mortar has good Excellent construction performance, softness and compressive strength, but the above-mentioned waterproof ordinary mortar and most of the existing ordinary mortars have a single color and cannot be used as a decorative surface, and the early strength is low, and the weight of ordinary mortar is relatively large , does not conform to the concept of environmental protection and green development in the construction industry
