Description
Technical field
The invention belongs to mortar concrete waterproofing agent technical field, be specifically related to a kind of mortar concrete waterproofing agent.
Background technology
Waterproofing work is occupied very important status in construction work, in construction work practice, because waterproofing work design is unreasonable, selection is incorrect, the coarse quality accident causing of constructing is of common occurrence, gently causes roofing and node seepage, whitewashes and come off; Heavy cause that underground works is not had by water logging, even building collapsing, suffers a loss national wealth, and jeopardizes people's life safety.Therefore, waterproofing work must obtain high-quality enforcement and guarantee.
The quality of water-proof material is that can waterproofing work obtain high-quality enforcement and ensure one of the most key link.Through development for many years, water-proof material can be divided into waterproof roll, waterproof paint, waterproof gasket cement, water-resisting agent etc. at present.Wherein, the construction of waterproof roll is comparatively loaded down with trivial details, waterproof paint and seal gum product are expensive again, only has water-resisting agent because forming organic whole with mortar and concrete layer, and then form one-piece construction with buildings, and its low cost, working procedure is significantly simplified, and is the development trend of future architecture waterproofing industry.But regrettably, although current water-resisting agent market product specification is many, product is price confusion not only, also there is very large defect in quality, has greatly affected result of use.As added soap in some water-resisting agent product, this can make the strength degradation approximately 25% of mortar and concrete layer; As the people such as Tang Ming (" Liaoning building materials " 2002 (1)) make waterproof layer intensity at least reduce by 26% problem for common soap water-resisting agent, take the method that adds water reducer to reduce water consumption to gain in strength, although reached effect, but in fact the workability of water reducer and mortar concrete has strict control, this method is inadvisable in engineering application.Also in some water-resisting agent product because of added small molecules silicoorganic compound (Guo Qingzhong. the research and development of organic silicon-fluorine buildings waterproof dust-proof material. the post-doctor of Zhongshan University academic dissertation .2007), not only make formed waterproof layer alkaline resistance properties very poor, cause the waterproof layer life-span shorter, also significantly delay the open hour of constructing simultaneously, the waterproof layer forming sometimes reach two days all unhardened.The and for example disclosed technical scheme of Chinese patent CN103073214A, only simply to have added the materials such as inorganic silicon compound, swelling agent, inorganic aluminate class to bring into play to fill closely knit effect, the use range of these products is limited, waterproof and anti-permeability performance are poor, the poor durability of waterproof layer, easy to crack.In addition, external giant as watt gram, the organosilicon water-proof emulsion of the preparation such as Degussa, although functional, price is high, is unfavorable for promoting.
Thereby construction waterproof layer intensity that existing water-resisting agent product exists is low, the open hour are long, water resistance is poor, the life-span is short, price is high, production and complicated construction technique etc., becomes water-resisting agent and be badly in need of the bottleneck problem solving in promoting.
