Description
Technical field:
The invention belongs to building material technical fields, and in particular to a kind of self-cure type concrete waterproofer and its preparation and make
Use method.
Background technique:
Currently, buildings waterproof is still the important technological problems in architectural engineering.China's concrete yield is huge, in order to improve
Its durability under conditions of use, the waterproof performance of concrete itself is always all by extensive concern.It is now commonly used to mention
The method of high concrete waterproof performance includes surface setting waterproof coating and self waterproofing etc..Using waterproofing agent is added, coagulation is improved
The method of itself native renitency water penetration ability is easy to operate, but engineering reliability, especially bad under the conditions of long-age.
This is mainly attributed to the appearance and expansion of concrete surface and internal microcrack.A kind of self-cure type concrete waterproofer is researched and developed, is led to
Repeatable alleviation, the intelligent mode crammed with microcosmic reparation concrete microcrack are crossed, the waterproof in the concrete life period is improved
Effect is an effective technological approaches.Entitled " the permeable crystallization type delivered such as big of the interim Huang of concrete magazine the 08th in 2010
The anti-permeability performance and its mechanism of crack self-healing concrete " in a text with regard to SJ penetrant crystalline composite material to distress in concrete self-healing
The influence for closing performance is studied, but is the self-healing mechanism of permeable crystallization type material and the invention patent involved in paper
It is different.The opinion of entitled " a kind of performance study of new water repellent " that fore-telling of the 08th phase Shen Er of marine traffic engineering magazine in 2015 etc. is delivered
The influence using the waterproofing agent of carboxylic acid, inorganic salts, potassium hydroxide and emulsifier preparation to concrete performance is had studied in text, but is discussed
Waterproofing agent described in text belongs to solvay-type, using the anti-capillary effect of holes as the mechanism of action.The 07th phase of door and window magazine in 2017
SAP is had studied to mixed in entitled " mechanical property and volume stability Journal of Sex Research of SAP self union concrete " text of vast and boundless Yi Fabiao
The influence of solidifying soil strength development rule and volume stability, but SAP is only discussed in paper to the Self-curing effect of concrete, do not have
Relate to the content that intelligence crams aspect." concrete waterproofer " of the Patent No. 201710396085.3 of Sichuan Province Yang little Ying
Patent is prepared using being illite powder, flyash, alum, white lime and calcium superphosphate as primary raw material, and building attic is suitable for
Waterproof and building kitchen and bath waterproof and tunnel etc. are often by the engineering of pressure water action and structures, without additional
Water-proofing treatment.A kind of only expansive waterproof agent, to autogenous healing problem without reference to.The patent of the Zhang Songbo of Guangxi province
Number it is related to a kind of permanent seal cooling concrete waterproofer for a kind of 201611084873.0 " permanent seal cooling concrete waterproofer " patent, it is former
Material includes waste glass powder, boron magnesium ore ground-slag, aluminum aluminum sulfate, polytetrafluoroethylene powder, ferric sulfate, triethanolamine.The permanent seal cooling coagulation
Native waterproofing agent significantly improves the impervious water-proof function of concrete, and seepage-resistant grade has enhancing up to P25 or more, and cracking resistance is resistance to
Acid-base property, the good effects such as anti-permeability strength height and resistance to ag(e)ing.This also belongs to a kind of scope of expansive waterproof agent.Jiangsu Province
A kind of " preparation method of selfreparing anti-crack concrete waterproofing agent " patent of the Patent No. 201611030249.2 of Yan Bowen
The preparation method for only describing a kind of selfreparing anti-crack concrete waterproofing agent, first prepares organic siliconresin, after then calcining
Egg shell reacted with water after, then react to obtain calcium gluconate with gluconic acid, by reducing the hydrated reaction heat of concrete, subtract
Few inside concrete heating, to reduce the crack of the mechanism blocking concrete of crack and penetrant crystalline, then carries out hydrophobisation
To reach waterproof purpose, this also belongs to compensation contraction, penetrant crystalline scope.In short, existing research achievement and paper are mostly
Using single or synthesis expansion, compensation are shunk and the mechanism of penetrant crystalline, and repeatable alleviation, intelligence are crammed and repaired with microcosmic
The research of multiple self-cure type waterproofing agent almost without.With the increasingly raising that modern architecture requires concrete durability, coagulation
Soil structure institute application environment it is increasingly complicated, there is an urgent need to research and develop new concrete waterproofing agent, with solve whole concrete structure and
The life cycle waterproofness technical problem of product.
Summary of the invention:
The purpose of the present invention is deficiencies in view of the above technical problems, provide a kind of self-cure type concrete waterproofer.
To achieve the above object, the invention adopts the following technical scheme:
A kind of self-cure type concrete waterproofer, including raw material and its weight percent are as follows: polycarboxylic acids powder 8~15%, it is unburned
Rubber powder 15.0 can be dispersed in straw powder 28~50%, fatty alcohol 1.0~1.5%, SHP-50 hydrophober 15.0~20.0%, 5044N
~20.0%, soluble polyvinyl alcohol 5.0~10.0%, polyacrylamide 1.0~1.5%, SAP particle 5.0~7.5%.
The unburned straw powder partial size is 80 mesh.
The SAP grain diameter is 120 mesh.
The preparation method of the self-cure type concrete waterproofer, comprising the following steps:
(1) according to the ratio, fatty alcohol is taken, the fatty alcohol solution that concentration is 15~20% is configured to；
(2) fatty alcohol solution is mixed in unburned straw powder, is mixed uniform, form homogeneous mixture；
(3) after drying to constant weight, according to the ratio, polycarboxylic acids powder, SHP-50 hydrophober, 5044N can be divided for homogeneous mixture
In homogeneous mixture after dissipating rubber powder, soluble polyvinyl alcohol, polyacrylamide and the incorporation drying of SAP particle, dry-mixed 5~
Uniform solid mixture, as self-cure type concrete waterproofer is made in 10min.
The application method of the self-cure type concrete waterproofer is as follows:
The self-cure type concrete waterproofer prepared is taken, in concrete mixing, adds cementitious material total weight thereto
1.0~3.0% self-cure type concrete waterproofer, stirs evenly.
The present invention also provides according to concrete mix, the method for adjustment and self-cure type of each raw material weight percentage
The moderate dosage of concrete waterproofer.
Beneficial effects of the present invention:
The present invention is to mix the waterproofing agent in concrete in one kind, during concrete hydrating, passes through unburned stalk
Powder absorption system improves concrete hole structure, and in concrete water-permeating, microcrack expansion, intelligence is coped with, and pore is crammed, and hinders
Disconnected penetrating passage, and it is sustained moisture, promote the further aquation of capillary hole wall cementitious material after infiltration, heal microcrack.It is one
Kind is crammed with repeatable alleviation, intelligence and the self-cure type waterproofing agent of microcosmic reparation concrete microcrack.
