Description

A kind of cement based penetration crystallization type water proofing paint
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of cement based penetration crystallization type water proofing paint.
Background technology
Used as a kind of material that current construction material application amount is maximum, concrete can be configured to varying strength, different performance And various buildings of different shapes, it is widely used in various engineering fields, and with preferable durability, normal Under the conditions of the use of 150-200 years is entirely possible.And crack expert professor Wang Tiemeng show that this is tied after summarizing relevant information By：In domestic and international reinforced concrete work, cracking rate reaches l5%~70%；The crack of outer wall of underground structure armored concrete More it is up to 80%~90%.According to 70 investigation results of dam of China, there is crack person to account for 100%.Seepage and solution is accounted for 87.5%, some concrete structures of China, the average life span of such as concrete dam is only about 30-50 years.Building cracks it is a large amount of Occur, have a strong impact on normal life and produce.
The prevention and reparation of building cracks, are always the problem of academia and engineering circles extensive concern.Cement-based penetrant knot Crystal formation waterproof material is then a kind of good Concrete crack repair material.
The content of the invention
It is an object of the invention to propose a kind of cement based penetration crystallization type water proofing paint, the coating is enabled to possess excellent The performances such as different impermeability pressure.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of cement based penetration crystallization type water proofing paint, including：
Organic waterproof agent 0.2-0.8%
Inorganic water-proof agent 0.5-1.5%
Complexing agent 0.1-0.5%
Active silicon additive 1-5%
Silicon ash 1-5%
Calcium hydroxide 1-5%,
Cement 50-70%
Superfine quartz sand 10-30%
Water reducer 0.5-1.5%.
Organic waterproof agent of the present invention is aliphatic acid waterproofing agent.
Inorganic water-proof agent of the present invention is inorganic aluminate water-proof agent.
Superfine quartz sand of the present invention, its particle diameter distribution is between 0.075mm-0.6mm.
Cement based penetration crystallization type water proofing paint of the present invention, properties meet GB GB18445-2001 《Cementitious capillary waterproofing material》In requirement to II type cement based penetration crystallization type water proofing paints.
The coating of the invention, to a mortar specimen of impermeability pressure 0.4MPa, in coating consumption in 0.8kg/m2 When, osmotic pressure ratio is 200%, has been reached in GB to being applied to the requirement of the I type coating of concrete sample；Coating consumption 1.0kg/m2When, reach in GB to being applied to the requirement of the II type coating of concrete sample；The mortar specimen for destroying coating still has There is preferably primary and secondary anti-molten ability.
Coating of the present invention can both improve the anti-permeability performance of matrix, be also remarkably improved matrix resisting carbonization and Resistance to chemical attack；
Active component is 28d, cement in curing age in coating of the invention：Sand：Water=1：3：Oozing in 06 matrix Saturating depth is located up to more than 15mm, and main penetrant crystalline product is C-S-H gels and a small amount of CaSiO3·nH2O.Penetration In Coating Crystallized product can reach part, and the porosity of matrix is decreased obviously, and more than 100nm is big, and hole number is significantly reduced.
Specific embodiment
Technical scheme is further illustrated below by specific embodiment.
