Problems solved by technology

[0003] At present, the market is flooded with a large amount of rigid waterproof slurry. Due to the large amount of cement in the powder, this type of product is likely to cause cracking and powdering on the surface of the mortar when it dries and forms a film. The cracking is particularly serious, even pulverized and peeled off, and the waterproof effect is lost; and because the liquid material contains a large amount of water, the surface strength and the actual strength after drying are slowly improved, which affects the subsequent construction process and delays the construction period

Abstract

The invention relates to the field of building waterproofing, and discloses modified-fiber-modified waterproofing slurry and a preparation method thereof. The waterproofing slurry is prepared from thefollowing components by weight: a powder material comprising 50-70 parts of Portland cement, 20-35 parts of quartz sand, 5-13 parts of quartz powder, 2-3 parts of metakaolin, 0.1-0.3 part of a dry powder water reducer, 0.1 to 0.3 part of a dry powder defoamer, 0.01 to 0.05 part of cellulose ether, 0.1 to 0.3 part of an organosilicon water repellent, 0.3 to 0.5 part of zinc stearate and 0.1 to 0.3part of glass fiber reinforced modified fiber, and a liquid material comprising 50-70 parts of water, 30-50 parts of emulsion, 0.1-0.3 part of an antifoaming agent, 0.1-0.3 part of a bactericide, 0.1- 0.3 part of a water reducing agent and 0.3 - 0.5 part of an antifreeze; wherein the ratio of liquid material: powder material is 1: (2.5 - 3). The modified-fiber-modified waterproofing slurry has ultra-high flexural and compressive strength, and due to the presence of the modified fiber, powder and residue falling and water-repellent layer peeling off caused by an external force can be effectively prevented.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a waterproof slurry modified by polymerized modified fibers and a preparation method thereof. Background technique [0002] Waterproof slurry is a two-component waterproof material specially used for building waterproofing. It is composed of a powder part and a liquid part in a certain proportion. Among them, the powder is composed of cement fine sand and unique active substances, while the liquid It is usually made of a fusion of polymers and additives. After the two groups of materials are mixed, they are painted on the cement base surface to achieve waterproof effect. [0003] At present, the market is flooded with a large amount of rigid waterproof slurry. Due to the large amount of cement in the powder, this type of product is likely to cause cracking and powdering on the surface of the mortar when it dries and forms a film. Cracking is particularly serious, even pulve...
