Abstract
The invention provides a waterproofing agent for buildings, which is convenient for construction and has favorable waterproof quality. The technical scheme is as follows: the waterproofing agent is composed of the following components in percentage by weight: 5-15% of stearic acid, 0.5-1.2% of polyvinyl alcohol, 2-3% of ammonia water, 0.6-0.7% of potassium hydroxide, 0.2-0.5% of emulsifier, 15-20% of alunite, 2-5% of naphthalene water reducing agent, 6-8% of carboxylate and the balance of water.
Description
Technical field
The present invention relates to a kind of concrete additive, be specifically related to a kind of building water-proof agent.
Background technology
Concrete member pore, sedimentation gap, crawling are the major causes of its infiltration.Water-resisting agent has the mixed clay mobility of hydrophobic, waterproof, increase and is easy to the functions such as pumping, microdilatancy.But still there is the bad problem that crack easily occurs of maintenance in the water-resisting agent of use at present.
Summary of the invention
The object of the invention has been to provide a kind of easy construction, building water-proof agent that water resistance is good.
To achieve these goals, the present invention is by the following technical solutions:
A kind of building water-proof agent is comprised of the component of following weight percent: stearic acid 5-15%: polyvinyl alcohol 0.5-1.2%, ammoniacal liquor 2-3%, potassium hydroxide 0.6～0.7%, emulsifying agent is 0.2-0.5, alunite 15-20%, naphthalene water reducer 2-5%, carboxylate salt 6-8%, surplus is water.
Preferably, a kind of building water-proof agent is comprised of the component of following weight percent: stearic acid 5%, and polyvinyl alcohol 1.2%, ammoniacal liquor 2%, potassium hydroxide 0.7%, emulsifying agent is 0.2%, alunite 20%, naphthalene water reducer 3.5%, carboxylate salt 8%, surplus is water.
Concrete slump and water-reducing rate after admixture 10% building water-proof agent of the present invention
Visible, at admixture after water-resisting agent of the present invention concrete there is larger diminishing and strong plasticizing function, the slump increases to some extent, and loses less.
Beneficial effect of the present invention:
Hydrophobic of the present invention, resistance to acids and bases, easy construction, water resistance is good, impermeabilisation intensity is high and ageing-resistant performance good.
