Abstract

The invention discloses cement base permeating crystallizing waterproof paint formed by reinforcing straw fibers, and belongs to the technical field of building materials. The cement base permeating crystallizing waterproof paint is compounded from the following raw materials in percentage by weight: 30-60% of silicate cement, 10-25% of modified magnesite cement, 10-25% of fillings, 5-12% of quartz sand, 0.1-0.5% of expanded vermiculite powder, 0.05-0.2% of straw fibers, 0.8-1.5% of a chelating agent, 0.5-2% of a crystallizing precipitant, 1-5% of an ionic equilibrium agent, 0.1-0.3% of an antifoaming agent, 0.1-1% of redispersible latex powder and 0.3-0.6% of a water reducing agent. The cement base permeating crystallizing waterproof paint formed by reinforcing the straw fibers, disclosed by the invention, has double waterproof properties, good permeation resistance, good self-healing and repair capacity, good water pressure resistant capacity and rapid crack repairing capacity, is simple in production technology, low in cost and environment-friendly, and has the same life as that of concrete.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a cement-based permeable crystalline waterproof coating reinforced by straw fibers. Background technique [0002] With the development of the construction industry and the increasing number of underground projects, people have put forward higher and higher requirements for the waterproofing of buildings and the moisture-proof and anti-corrosion materials of underground projects. Building waterproof material is an important part of construction engineering, and its performance directly affects the service life and function of the building. Compared with traditional waterproof materials, cement-based permeable crystalline waterproof coatings have incomparable advantages in many fields, especially waterproof projects such as underground waterproof projects, backwater projects and reservoirs. [0003] Cement-based permeable crystalline waterproof material is a...
