Abstract
A kind of waterproofing agent, is made up of as following weight percent each component：Carboxylic styrene butadiene latex 15-30%, waterproofing agent of organosilicon 5-20%, silica 2-15%, barium hydroxide 5-10%, dodecyl sodium sulfate 0.2-1%, defoamer 1-3% and deionized water 20-45%.Beneficial effects of the present invention are：Penetration is strong, and hydrophobicity is good, environmentally friendly, and the waterproof layer of formation has lotus leaf water droplet effect, does not influence facade, and active material to penetrate into inside concrete and form the hole that a large amount of insoluble crystal block concrete, plays the effect of permanent waterproof.
Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of crystal type architectural waterproof material.
Background technology
The characteristics of waterproof material has low temperature flexibility, self-healing property and adhesive property good, can normal temperature construction, speed of application is fast and meets environmental requirement.Especially without Hot-melt construction, remove the sorrow of fire from.Waterproof material resistance to low temperature is good, it is adaptable to waterproof of the industry with the roofing of civil building, basement, interior, municipal works, cistern, swimming pool, subway and tunnel, moistureproof and sealing.It is particularly suited for needing the military installations of cold construction and the water-tight corrosion-proof engineering such as oil depot, chemical plant, textile mills, grain depot of naked light should not be employed.
Concrete is a kind of composite porous, it is internal containing substantial amounts of hole and micro-crack, some corrosive mediums (such as villaumite, sulfate) can be in the presence of water as these defects enter inside concrete, these materials can corrode reinforcing bar, badly influence durability and the life-span of concrete structure.
The emphasis that concrete protection considers is exactly water resistance, is broadly divided into flexible water and rigid waterproofing.Flexible water refers to carry out outsourcing waterproof to structure with waterproof roll or water-repellent paint, so as to realize building waterproof.Rigid waterproofing refers to that building structure waterproof is realized by concrete body waterproof, that is, improve the impermeability of concrete, blocks the hole of concrete, prevents moisture from entering inside concrete.The anti-permeability performance by adding waterproofing agent raising concrete main at present, common waterproofing agent mainly has chloride salt, stearic acid salt, waterproofing agent of organic silicon etc..Wherein the impervious effect of chloride salt is fine, but Chloride Attack reinforcing bar, reduce building service life.Stearic acid salt is poor with the impervious effect of organic silicon waterproofing agent, does not reach seepage resistance demand.Organic silicon waterproofing agent has the advantages that penetrating power is strong, hydrophobicity is good but impermeability is poor.
The good and bad jumbled together in current waterproof material market, and especially cement-based penetrant waterproof material is even more uneven, it is impossible to ensure waterproof effect, causes the complaint of a large number of users.So solving the problem of waterproofing industry in the urgent need to a kind of novel concrete base osmotic crystalline waterproof material at present, good economic benefit and social benefit is brought.
The Chinese invention patent of Application No. 201110191320.6 discloses a kind of capillary crystalline waterproofing agent, the invention product only to concrete serve raising density and it is impervious the characteristics of, harm of the sulfate ion to concrete, and product can not be eliminated for milky white liquid is not colorless and transparent.And capillary crystalline waterproof agent prepared by the present invention is colourless transparent liquid, inorganic substances barium hydroxide penetrates into inside concrete reaction generation Barium sulfate crystals and blocks concrete pore, the sulfate ion in concrete is reduced while generation Barium sulfate crystals, infringement of the sulfate to concrete is reduced.
The content of the invention
Technical problem solved by the invention is to provide a kind of waterproofing agent and preparation method thereof, is used by directly brushing, for the waterproof protective treatment of concrete.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of waterproofing agent, is made up of as following weight percent each component：Carboxylic styrene butadiene latex 15-30%, waterproofing agent of organosilicon 5-20%, silica 2-15%, barium hydroxide 5-10%, dodecyl sodium sulfate 0.2-1%, defoamer 1-3% and deionized water 20-45%.
The waterproofing agent of organosilicon is water white transparency methane-siliconic acid sodium solution, and methane-siliconic acid sodium content is 20-40%.
Preferably, a kind of waterproofing agent, is made up of as following weight percent each component：Carboxylic styrene butadiene latex 25%, waterproofing agent of organosilicon 15%, silica 1 0%, barium hydroxide 8%, dodecyl sodium sulfate 0.5%, defoamer 2% and deionized water 39.5%.
The waterproofing agent of organosilicon is water white transparency methane-siliconic acid sodium solution, and methane-siliconic acid sodium content is 35%.
The present invention also provides a kind of preparation method of waterproofing agent is：
By weight successively by water, carboxylic styrene butadiene latex, waterproofing agent of organosilicon, silica, dodecyl sodium sulfate, barium hydroxide addition reactor, it is then heated to reaction temperature, stirring, is cooled to after room temperature after being filtered to remove impurity, that is, obtain waterproofing agent of the invention.
The reaction temperature is 60 DEG C~70 DEG C, and mixing time is 30min~60min.
